# Line 1  Line 1 
1  Version CVS HEAD (?)  Version SVN trunk (?)
2    
3      * general changes:
4        - Fixed compiler error in Pool.h.
5        - Require C++11 compiler support.
6        - Autoconf: Added m4/ax_cxx_compile_stdcxx.m4 macro which is used
7          for checking in configure for C++11 support (as mandatory
8          requirement) and automatically adds compiler argument if required
9          (e.g. -std=C++11).
10        - RTMath: Implemented floating point comparison methods
11          fEqual32(float,float) and fEqual64(double,double) which take the
12          expected floating point tolerances into account.
13    
14      * Real-time instrument scripts:
15        - Added method ScriptVM::setExitResultEnabled() which allows to
16          explicitly enable the built-in exit() function to optionally accept
17          one function argument; the value of the passed exit() function
18          argument will then become available by calling
19          VMExecContext::exitResult() after script execution.
20        - 64 bit support for NKSP integer scripts variables (declare $foo).
21        - Variable names, function names and preprocessor condition names must start
22          with a regular character (a-z or A-Z); starting them with a digit or
23          underscore is not allowed.
24        - NKSP parser fix: equal comparison operator "=" and not equal comparison
25          operator "#" must only accept integer operands.
26        - NKSP language: Implemented support for standard units like Hertz, seconds,
27          Bel including support for metric unit prefixes; so one can now e.g.
28          conveniently use numbers in scripts like "5us" meaning "5 microseconds",
29          or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
30          "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
31        - NKSP language: Introduced "final" operator "!" which is specifically
32          intended for synthesis parameter values to denote that the synthesis
33          parameter value is intended to be the "final" value for that synthesis
34          parameter that should explicitly be used by the engine and thus causing
35          the sampler engine to ignore all other modulation sources for the same
36          synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
37          variable or formula with this new "!" operator the expression is marked as
38          being "final".
39        - NKSP script editor API: Added support for detecting standard unit tokens
40          and their potential metric prefix token.
41        - NKSP language: Added support for NKSP real number literals and
42          arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
43        - NKSP language: Added support for NKSP real number (floating point) script
44          variables (declare ~foo).
45        - NKSP language: Added support for NKSP real number (floating point) array
46          script variables (declare ?foo[]).
47        - Built-in script function "message()" accepts now real number argument as
48          well.
49        - Added built-in script function "real_to_int()" and its short hand form
50          "int()" for casting from real number to integer in NKSP scripts.
51        - Added built-in script function "int_to_real()" and its short hand form
52          "real()" for casting from integer to real number in NKSP scripts.
53        - Allow built-in exit() function to potentially accept real number type
54          argument as well.
55    
56      * test cases:
57        - Fixed compiler errors in test cases.
58        - Updated README for how to compile & run test cases.
59        - Updated test case
60          MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
61          expected behaviour of the Mutex class implementation (recursive
62          mutex type).
63        - Added test cases for NKSP core language aspects and core built-in
64          functions.
65        - Fixed thread tests segfaulting on Linux.
66        - NKSP: Added real number test cases for built-in functions exit(),
67          int_to_real(), real(), real_to_int() and int(), as well as for the
68          plus, minus and negate language operators.
69    
70    Version 2.1.1 (27 Jul 2019)
71    
72      * Real-time instrument scripts:
73        - Fixed behavior of built-in NKSP functions change_sustain(),
74          change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
75          and change_cutoff_release().
76    
77      * general changes:
78        - Only play release trigger samples on sustain pedal up if this behaviour
79          was explicitly requested by the instrument (otherwise only on note-off).
80        - Fixed compiler warnings.
81        - Fixed compilation error when cross-compiling to Mac.
82        - FX Sends: Provide more useful error messages on routing problems
83          (see bug #169).
84        - LSCP doc: Be more clear describing the two distinct approaches
85          of using external vs. internal effects (see bug #169).
86        - "optional" class: Fixed comparison operators.
87    
88      * Gigasampler/GigaStudio format engine:
89        - Format extension: If requested by instrument then don't play release
90          trigger sample on note-off events.
91    
92      * SFZ format engine:
93        - Fixed memory leak when releasing samples
94          (fixes bug #307, patch by Jacek Roszkowski)
95        - Fixed potential crash when a sample is shared by more than one region
96          (fixes bug #308, patch by Jacek Roszkowski).
97        - Opcode 'sample': Added support for built-in sample '*silence'
98          (fixes bug #310, patch by Jacek Roszkowski).
99    
100    Version 2.1.0 (25 Nov 2017)
101    
102      * SFZ format engine:
103        - added support for <global>, <master> and #define (patch by Alby M)
104        - Removed code duplication in SFZ file loading code.
105        - Added support for sfz extension opcode 'script' which may be used to
106          load real-time instrument script file (NKSP script language).
107        - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
108        - Fixed unintended volume fade-in of voices under certain conditions.
109        - sfz parser: allow missing space between header and opcode
110    
111      * Gigasampler/GigaStudio format engine:
112        - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
113          cutoff settings.
114        - Got rid of resembling an ancient GSt misbehavior which did not pitch at
115          all if an up-pitch of more than 40 semi tones was requested (I don't
116          think there is any stock gig sound that requires this behavior to
117          resemble its original sound).
118        - Added support for controlling whether the individual EGADSR stages may
119          be aborted (as LinuxSampler extension to the original GigaStudio 4
120          format).
121    
122      * general changes:
123        - fixed printf type errors (mostly in debug messages)
124        - use unique_ptr instead of auto_ptr when building with C++11
125        - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
126          allowing to sort data efficiently in real-time safe manner.
127        - RTList class: added methods for moving/inserting elements to arbitrary
128          position within a list.
129        - RTList class: added method fromPtr() for creating an Iterator object from
130          a raw element pointer.
131        - Attempt to partly fix resetting engine channels vs. resetting engine, an
132          overall cleanup of the Reset*(), ConnectAudioDevice(),
133          DisconnectAudioDevice() API methods would still be desirable though,
134          because the current situation is still inconsistent and error prone.
135        - Active voices are now internally grouped to "Note" objects, instead of
136          being directly assigned to a keyboard key. This allows more fine graded
137          processing of voices, which is i.e. required for certain instrument
138          script features.
139        - Fix: Release trigger voices were not spawned on sustain pedal up
140          (CC #64) events.
141        - Fix: Release trigger voices can now also distinguish correctly between
142          note-off and sustain pedal up events.
143        - All engines: Increased ramp speed of volume smoother and pan smoother
144          (while slow rate of crossfade smoother is preserved) to allow quick
145          volume and pan changes by instrument scripts for instance.
146        - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
147          properly and thus were ignored for certain uses.
148        - Added new C++ API method
149          VirtualMidiDevice::SendChannelPressureToSampler().
150        - windows, 32-bit: fixed potential crashes by making sure the stack in
151          sub threads is 16-byte aligned
152        - fixed numerous compiler warnings
153        - Fixed invalid (note-on) event ID being assigned to new Note objects.
154        - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
155          fixes potential undefined behavior.
156        - Fixed Note object leak when triggering notes on keys which did not
157          have a valid sample mapped (fixes bug #252).
158        - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
159        - linuxsampler binary fix: option --create-instruments-db ignored
160          subsequent optional argument due to glibc's implementation oddity
161          which expects a "=" sign, but no space between them.
162    
163      * packaging changes:
164        - removed unnecessary dependency to libuuid
165          (originated by libgig's usage of it)
166        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
167          auto detect whether it (sh/c)ould output its messages in color.
168        - Debian: Fixed packaging error about invalid "Source-Version"
169          substitution variable.
170        - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
171        - Debian: Added build dependency to libsqlite3-dev for building
172          linuxsampler with instruments DB support.
173    
174      * Real-time instrument scripts:
175        - Implemented scheduler for delayed MIDI events and for suspended scripts.
176        - Built-in script function "wait()": implemented support for function's
177          "duration-us" argument, thus scripts using this function are now
178          correctly resumed after the requested amount of microseconds.
179        - Built-in script function "play_note()": implemented support for
180          function's "duration-us" argument, thus notes triggered with this
181          argument are now correctly released after the requested amount of
182          microseconds.
183        - Fix: script events were not cleared when engine channel was reset,
184          potentially causing undefined behavior.
185        - Fixed crash which happened when trying to reference an undeclared
186          variable.
187        - Built-in script function "play_note()": Added support for passing
188          special value -1 for "duration-us" argument, which will cause the
189          triggered note to be released once the original note was released.
190        - Instrument script classes now exported with the liblinuxsampler C++ API.
191        - Added new API method ScriptVM::syntaxHighlighting() which provides
192          a convenient syntax highlighting backend for external instrument
193          script editor applications.
194        - Added new C++ API class "ScriptVMFactory".
195        - Extended parser issues to provide not only first line and first
196          column, but also last line and last column of issue (thus marking
197          the precise span of the issue within the source code).
198        - Reload script automatically after being modified by an instrument
199          editor.
200        - NKSP language grammar correction: allow empty event handler bodies
201          like "on note end on".
202        - Implemented built-in script function "change_vol()".
203        - Implemented built-in script function "change_tune()".
204        - Implemented built-in script function "change_pan()".
205        - Implemented built-in script function "change_cutoff()".
206        - Implemented built-in script function "change_reso()".
207        - Implemented built-in script function "event_status()".
208        - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
209          "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
210          "event_status()" function.
211        - NKSP language: Added support for bitwise operators ".or.", ".and."
212          and ".not.".
213        - NKSP language scanner: Fixed IDs matching to require at least one
214          character (i.e. when matching function names or variable names).
215        - NKSP language scanner: disabled unusued rules.
216        - Fixed behavior of play_note() and note_off() functions which must
217          be distinguished engine internally from "real" MIDI note on/off
218          events in order to avoid misbehaviors like hanging notes.
219        - Implemented built-in script variable "$KSP_TIMER".
220        - Implemented built-in script variable "$NKSP_REAL_TIMER".
221        - Implemented built-in script variable "$NKSP_PERF_TIMER".
222        - Implemented built-in script variable "$ENGINE_UPTIME".
223        - Implemented built-in script function "inc()".
224        - Implemented built-in script function "dec()".
225        - NKSP language fix: division expressions were evaluated too often.
226        - NKSP language fix: string concatenation operator was right
227          associative instead of left (to right).
228        - NKSP language correction: allow empty statements in entire language
229          (i.e. "if end if").
230        - Implemented built-in script function "stop_wait()".
231        - Implemented built-in script variable "$NI_CALLBACK_ID".
232        - Implemented built-in script variable "$NI_CALLBACK_TYPE".
233        - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
234        - Added support for read-only built-in variables (respectively
235          handled by the script parser).
236        - Added built-in script constant "$NI_CB_TYPE_INIT".
237        - Added built-in script constant "$NI_CB_TYPE_NOTE".
238        - Added built-in script constant "$NI_CB_TYPE_RELEASE".
239        - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
240        - NKSP Language: Added support for user defined script functions.
241        - Implemented built-in script function "change_attack()".
242        - Implemented built-in script function "change_decay()".
243        - Implemented built-in script function "change_release()".
244        - Fixed all change_*() built-in script functions to apply their
245          synthesis parameter changes immediately in case the respective note
246          was triggered at the same time, instead of scheduling the parameter
247          change, especially because it would cause some parameter types's
248          changes either to be ramped (i.e. change_vol()) or other types even
249          to have not effect at all (i.e. change_attack()).
250        - Implemented built-in script function "sh_left()".
251        - Implemented built-in script function "sh_right()".
252        - Implemented built-in script function "min()".
253        - Implemented built-in script function "max()".
254        - NKSP Fix: "init" event handler was not always executed when a script
255          was loaded.
256        - NKSP built-in wait() script function: abort script execution if
257          a negative or zero wait time was passed as argument (since this is
258          a common indication of a bug either of the script or even of the
259          engine, which could lead to RT instability or even worse).
260        - ScriptVM: Implemented automatic suspension of RT safety
261          threatening scripts.
262        - Provide more user friendly error messages on syntax errors.
263        - Fixed NKSP parser warning "Not a statement" when assigning an
264          initializer list to an array variable.
265        - Implemented built-in script array variable "%ALL_EVENTS".
266        - Implemented built-in script function "in_range()".
267        - Implemented built-in script function "change_amp_lfo_depth()".
268        - Implemented built-in script function "change_amp_lfo_freq()".
269        - Implemented built-in script function "change_pitch_lfo_depth()".
270        - Implemented built-in script function "change_pitch_lfo_freq()".
271        - Implemented built-in script function "change_vol_time()".
272        - Implemented built-in script function "change_tune_time()".
273        - Implemented built-in script function "fade_in()".
274        - Implemented built-in script function "fade_out()".
275        - Fixed acceptance of wrong data type of parameters passed to built-in
276          script functions "change_vol()", "change_tune()", "change_pan()",
277          "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
278          "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
279          "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
280        - Added built-in script function "get_event_par()" and implemented some
281          of its possible parameter selections.
282        - Added built-in script function "set_event_par()" and implemented some
283          of its possible parameter selections.
284        - Fixed a bunch of scheduler time related bugs.
285        - Fixed polyphonic variables not being reset to zero after usage.
286        - Built-in "ignore_event()" function: argument is now optional, like with
287          built-in function "ignore_controller()".
288        - Implemented built-in script function "change_velo()".
289        - Implemented built-in script function "change_note()".
290        - Adjusted behavior of "change_vol()" and "change_tune()" to a more
291          intuitive behavior if used in combination with "change_vol_time()" or
292          "change_tune_time()" respectively: now tuning/volume changes are only
293          assigned (without delay) immediately to a new note if the respective
294          timing function has not been called before, otherwise the volume/tuning
295          changes are automatically faded (before, only the event's time stamp was
296          relevant).
297         - Implemented built-in script function "array_equal()".
298         - Implemented built-in script function "search()".
299         - Implemented built-in script function "sort()".
300         - NKSP Fix: Never suspend "init" event handlers.
301         - Implemented built-in script function "same_region()" (currently only
302           available for gig format engine).
303         - Added built-in script constant "$NKSP_LINEAR".
304         - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
305         - Implemented built-in script function "change_vol_curve()".
306         - Implemented built-in script function "change_tune_curve()".
307         - built-in "play_note()" function now supports a sample playback start
308           offset with argument 3, where special value -1 means to use the regular
309           sample offset as defined by the instrument file.
310         - Built-in array variable %KEY_DOWN[] is now a read-only variable.
311         - Built-in variable $EVENT_NOTE is now a read-only variable.
312         - Built-in variable $EVENT_VELOCITY is now a read-only variable.
313         - built-in "play_note()" function now accepts -2 for its fourth argument
314           (note duration) which means the life time of the note shall be sticked
315           to the requested note number of argument 1.
316         - Fix: built-in "play_note()" function now returns 0 as result value if
317           -1 was passed for its fourth argument (note duration) and the respective
318           parent note is already gone.
319        - Implemented built-in script function "change_play_pos()".
320        - NKSP language: Added support for user declared const array variables.
321        - NKSP language: Raise parser warning if array variable is accessed with
322          an index that exceeds the array's size.
323        - NKSP language fix: Unknown characters were not handled correctly.
324        - NKSP language: Added support for "synchronized .. end synchronized"
325          code blocks.
326        - Implemented built-in script function "abort()" which allows to abort
327          another script handler by passing its callback ID.
328        - Fixed potential memory access bug and potential undefined behavior of
329          "init" event handlers.
330        - Print a time stamp along to each call of built-in function "message()".
331        - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
332          to retrieve all code blocks filtered out by the preprocessor.
333        - Added built-in script function "fork()".
334        - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
335        - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
336        - Fixed potential crash when accessing dynamic built-in array variables.
337        - Added built-in script function "callback_status()".
338        - Added built-in constant $CALLBACK_STATUS_TERMINATED.
339        - Added built-in constant $CALLBACK_STATUS_QUEUE.
340        - Added built-in constant $CALLBACK_STATUS_RUNNING.
341        - Removed max. value limitation of built-in functions "change_attack()",
342          "change_decay()" and "change_release()" to i.e. allow passing 2000000
343          for doubling the respective time.
344        - NKSP script editor syntax highlighting API: Fixed app termination due
345          to a lexer start condition stack underrun.
346        - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
347          USE_CODE_IF_NOT() preprocessor statements.
348        - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
349          can be set to disable all subsequent built-in "message()" function calls
350          on preprocessor level.
351        - Implemented built-in script function "change_sustain()".
352        - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
353          to avoid the editor app to crash on ill-formed text input.
354        - Added built-in script function "change_pan_time()".
355        - Added built-in script function "change_pan_curve()".
356        - Added built-in script function "change_cutoff_attack()".
357        - Added built-in script function "change_cutoff_decay()".
358        - Added built-in script function "change_cutoff_sustain()".
359        - Added built-in script function "change_cutoff_release()".
360        - Added built-in script function "change_cutoff_lfo_depth()".
361        - Added built-in script function "change_cutoff_lfo_freq()".
362    
363      * Instruments DB:
364        - Fixed memory access bug of general DB access code which lead to
365          undefined behavior.
366        - Cleanup of instruments DB file creation and opening code.

411          in order to get rid of warnings from automake 1.14
412    
413      * general changes:
414        - Refactoring: moved the independent code from
415          the Gigasampler format engine to base classes
416        - command line option '--profile' is currently disabled, since the
417          respective profiling code is currently broken
418        - Introduced support for optional environment variable
419          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
420          where the sampler shall look for instrument editor plugins
421          (patch by Luis Garrido, slightly modified).
422        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
423        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
424        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
425          note (in this implementation of the sampler its simply hard routed to
426          the 1st effect send of the sampler channel, no matter what the actual
427          effect type is)
428        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
429          note (in this implementation of the sampler its simply hard routed to
430          the 2nd effect send of the sampler channel, no matter what the actual
431          effect type is)
432        - implemented support for internal LADSPA effects
433        - raised limit of program change queue from 100 to 512
434          (as suggested by Alex Stone)
435        - implemented sine LFO, pulse LFO and saw LFO
436        - experimental support for per voice equalization
437        - added command line option --exec-after-init
438        - Introduced new C++ API method:
439          EngineChannel::InstrumentFileName(int index)
440          allowing to retrieve the whole list of files used for the loaded
441          instrument on an engine channel (a.k.a. part). Some GigaStudio
442          instruments for example are splitted over several files like
443          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
444        - Added new C++ API method Sampler::GetGlobalMaxVoices().
445        - Added new C++ API method Sampler::GetGlobalMaxStreams().
446        - Added new C++ API method Sampler::SetGlobalMaxVoices().
447        - Added new C++ API method Sampler::SetGlobalMaxStreams().
448        - Various "const" and "restrict" optimizations.
449        - all engines: add pan CC value to instrument pan parameter before
450          applying panning, instead of using two separate pan functions in
451          series (#182)
452        - added a lock guard class for exception safe mutex handling and
453          used it everywhere appropriate
454        - Immediately apply scale tuning changes to active voices.
455        - Exposed scale tuning to C++ API (along to the already existing standard
456          SysEx way).
457        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
458          and broken for ppc64. (Seq_cst loads and stores are actually not
459          used in LS, so the bug wasn't noticable.)
460        - lsatomic.h: added ARMv7 support
461        - Added support for multiple MIDI input ports per sampler channel (and
462          added various new C++ methods for this new feature / design change, old
463          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
464          as deprecated but are still there and should provide full behavior
465          backward compatibility).
466        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
467          unsafe and caused compilation error with clang 2.x).
468        - Bugfix: only process the latest MIDI program change event.
469        - Introducing the LSCP shell, which provides convenient control of the
470          sampler from the command line by providing LSCP aware features.
471        - VirtualMidiDevice: Added support for program change.
472        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
473        - VirtualMidiDevice: Added support for pitch bend.
474        - Aftertouch: extended API to explicitly handle channel pressure and
475          polyphonic key pressure events (so far polyphonic pressure was not
476          supported at all, and channel pressure was rerouted as CC128 but not
477          used so far).
478        - Added initial support for real-time instrument scripts. The script VM
479          code is shared by all sampler engine implemementations, however only the
480          gig file format currently provides support for storing instrument scripts
481          (as LinuxSampler extension to the original GigaStudio 4 format).
482    
483      * Gigasampler format engine:
484        - implemented the "round robin keyboard" dimension
485        - fixed round robin and random dimensions for cases when number of
486          dimension zones is not a power of two
487        - made round robin use a counter for each region instead of each
488          key
489        - bugfix: pitch LFO controller "internal+aftertouch" was broken
490        - bugfix: filter keyboard tracking was broken
491        - filter performance fix (an unnecessary copy was made of the
492          filter parameters in each sub fragment)
493        - handle special case when pan parameter in gig file has max or
494          min value
495        - Exclusive Groups: don't ever stop voices of the same note,
496          doesn't sound naturally with a drumkit
497        - fixed EG1 modulation when attack or release is zero
498        - Fixed support for 'aftertouch' attenuation controller.
499        - Fixed crash that happened with velocity split sounds under certain
500          conditions (see also previous commit on libgig).

509        - added support for trigger=first, trigger=legato and sw_previous
510        - allow non-numerical key values ("C#4" for example)

512        - fixed error when unloading instrument with same sample used by
513          multiple regions

521        - fine-tuned the default velocity curve
522        - added support for transpose
523        - fixed crash when using sw_down/up
524        - improved logic for sw_lokey/hikey/up/down/last
525        - added more v1 aliases to parser
526        - reduced memory usage for sfz data
527        - RT-safeness: avoid malloc in audio thread

536        - use loop markers from sample file if loop_start and loop_end are
537          not set in sfz file

682          incorrectly set to two. This caused silence in Cubase 5.
683        - save engine type (gig, sfz or sf2) in plugin state
684        - VST: when opening Fantasia, look for both 32 and 64 bit Java on

698        - LV2: use the new lv2 package if present
699        - VST: try to open Fantasia automatically on Linux and Mac too (on
700          Linux, the Fantasia jar should be placed in <prefix>/share/java)
701        - VST: fixed crashes on Linux Ardour and EnergyXT
702        - DSSI bugfix: it wasn't possible to change engine type. The MIDI
703          port and audio channel routing for DSSI plugins are now visible.
704        - LV2: use urid and atom extensions instead of deprecated uri-map
705          and event
706        - LV2: lv2 package 1.0 is now required to build the LV2 plugin
707        - LV2: changed number of output channels to 16 stereo, just like
708          the VST and AU plugins
709        - LV2: fixed save/restore of SFZ state (patch by David Robillard)
710        - LV2: made LV2 plugin buildable on Windows and Mac

712          sampler's internal MIDI instrument mapping system
713    
714      * Instrument editor interface:
715        - Changed instrument editor plugin interface, providing additional
716          informations like the EngineChannel for which the instrument editor was
717          spawned for. This allows the instrument editors to interact more actively
718          with the sampler.
719    
720      * MIDI driver:
721        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
722          the ALSA sequencer client name

724          there is no reason for this limit
725        - MME: fixed memory handling bug found with cppcheck
726        - MME: removed compiler warning
727        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
728          which allows to retrieve the list of CoreMIDI clients / ports and to connect
729          to them a la JACK, via the usual sampler APIs
730        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
731          the driver will automatically connect to other CoreMIDI clients' ports
732          (e.g. external MIDI devices being attached to the Mac)
733        - added support for MIDI note on velocity filter
734        - CoreMIDI: fixed memory deallocation error
735        - Fixed variable underflow in VirtualMidiDevice, which caused graphical
736          virtual keyboards in frontends / instrument editors being stuck.
737        - Bugfix in VirtualMidiDevice: process note on with velocity 0 as note off.
738        - Implemented missing handling of MIDI "running status".
739        - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
740        - MME bugfix: driver wasn't closed properly
741        - CoreMIDI: automatically connect to all input sources by default (driver
742          parameter "AUTO_BIND").
743        - CoreMIDI: fixed auto bind feature to CoreMIDI ports that go online
744        - CoreMIDI: fixed minor memory leak
745    
746      * audio driver:
747        - ASIO driver fixes for newer gcc versions (fix from PortAudio)
748        - JACK audio: react on sample rate changes.

751          RT context.
752        - ASIO driver: removed compiler warnings
753        - CoreAudio: fixed minor error handling bug
754        - ASIO driver: be more verbose when no ASIO card could be found (fixes #203)
755        - JACK audio: return the JACK server's current sample rate as default value
756          for audio device parameter "SAMPLERATE" (fixes #166).
757    
758      * LSCP server:
759        - added support for sending MIDI CC messages via LSCP command
760          "SEND CHANNEL MIDI_DATA CC <sampler-chan> <ctrl> <val>"

803        - Show all possible next symbols immediately right to the current command
804          line while typing (no double tab required for this feature, as it would
805          be the case in other shells).
806        - Added support for moving cursor left/right with arrow keys.
807        - Added support for built-in LSCP reference documentation, which will
808          automatically show the relevant LSCP reference section on screen as soon
809          as one specific LSCP command was detected while typing on the command

828          or no argument).
829        - Implemented built-in script function "set_controller()".
830        - Added extended script VM for the Gigasampler/GigaStudio format sampler
831          engine, which extends the general instrument script VM with Giga format
832          specific variables and functions.
833        - Giga format scripts: added built-in script int constant variables
834          $GIG_DIM_CHANNEL, $GIG_DIM_LAYER, $GIG_DIM_VELOCITY, $GIG_DIM_AFTERTOUCH,

859          handler to "release" event handler.
860        - Fixed crash when using built-in script function "by_marks()".

864        - minor valgrind fixes
865        - fixed crash which occurred when changing an already deployed sampler
866          channel to a different engine type
867        - fixed crash when deleting a sampler channel or changing engine
868          type while an instrument load was in progress
869        - bugfix: playing a note while changing the instrument could cause
870          a crash, or give "Handing back unknown region" error messages
871        - bugfix: calling SET VOICES (which Fantasia does on start and
872          refresh) could cause instruments to be unloaded
873        - Mac OS X: fixed name collision of enum in EffectControl and
874          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
875        - Mac OS X: fixed hanging threads
876        - Windows: disabled the previous thread fix on non-Mac systems, as
877          it caused hanging threads on Windows
878        - Fixed possible crashes due to corrupted MIDI/audio device list
879          after MIDI/audio device creation failure
880        - When creating MIDI instrument map entries with "PERSISTENT" type, the
881          instruments were uselessly precached with zero samples, however it still
882          took the full preloading time and on 1st program change the respective
883          instrument was completely reloaded again.
884        - fixed handling of rapid bank select and program change messages
885          sent to the same sampler channel (patch from the Open Octave
886          project, slightly adjusted)
887        - fixed crash when trying to create an effect instance with controls
888          which min and/or max values depend on the sample rate
889        - fixed bug #162
890        - bugfix: LADSPA_PATH was not evaluated correctly when containing
891          multiple paths (#165)
892        - thread safety fixes for the instrument loading thread
893        - bugfix: instrument loading crashed for sfz and sf2 in Ardour

897        - Mac OS X: fixed crash when unloading plugin on 10.7 and later
898        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
899          introduced in previous fix)
900        - fixed crash when a channel received a program change while
901          playing a note in a key group
902        - fixed erroneous error message piping in VoiceBase.h
903          (labelled "Disk stream not available in time")
904        - Update effects on sample rate & period size changes (to avoid
905          crashes and noise on such transitions).
906        - ignore missing LADSPA paths without ignoring valid LADSPA paths
907          (fixes #208)
908        - Fixed bug in LSCP grammar definition which caused a statement like
909          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
910          practically irrelevant, however it caused problems with the new LSCP
911          shell's auto completion feature).
912        - Fixed MIDI program change messages being ignored if quickly executed
913          after each other (fixes #231).
914    
915    Version 1.0.0 (31 July 2009)
916    
917      * packaging changes:
918        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
919          causing e.g. the libgig test to fail when
920          "./configure --disable-jack-driver" was used
921          (patch by Alexis Ballier)
922        - fixed compilation with gcc 4.3
923        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
924        - fixed configure so it detects x86_64 (#107)
925        - fixes for building with newer MinGW versions
926        - fix for building with bison 2.4 (#111)
927        - fixed building with libgig installed in a non-standard directory
928        - minor fix in configure for mmsystem.h detection on MinGW
929        - Windows: look for editor plugins and Fantasia using base
930          directory of liblinuxsampler dll (look in the same directory and one
931          directory above)
932        - configure script fix: removed unconditional use of SSE
933        - fixed building with sqlite installed in a non-standard directory
934        - when cross-compiling, don't try to create instruments.db
935        - fix for new mingw-w64 version, which has usleep
936    
937      * general changes:
938        - bugfix: on some POSIX systems instrument editor plugins refused to
939          load as we used a non-portable Linux specific struct field
940          (fixes bug #70, patch by Ronald Baljeu)
941        - fixed endless loop which occured when loading an instrument editor
942          plugin DLL on Windows systems failed
943        - fixed memory leaks that occurred when liblinuxsampler was unloaded
944        - optimized the SynchronizedConfig class so it doesn't wait
945          unnecessarily long after an update
946        - added support for notifying instrument editors on note-on / note-off
947          events (e.g. to highlight the pressed keys on the virtual keyboard
948          of gigedit)
949        - added support for triggering notes by instrument editors (see above)
950        - be verbose on DLL load errors (on Linux)
951        - fixed di-harmonic triangle LFO implementation (this LFO implementation
952          is only used by very few systems, most pick the int math
953          implementation, which is usually faster)
954        - fixes for audio drivers with varying buffer sizes
955        - experimental support for running LinuxSampler as a DSSI, LV2 and
956          VST plugin
957        - notification events for stream/voice count statistics are now sent
958          only when there are actual changes
959        - added memory ordering constraints to improve stability on
960          multi-core and multi-cpu systems
961        - maximum voices and disk streams can now be altered at runtime
962        - fixed CPU feature detection on x86_64 (maybe fixes #108)
963        - automatic stacktrace mechanism is now turned off by default and can
964          be switched on by command line option "--stacktrace" (the automatic
965          stacktrace mechanism seems to be broken on most systems at the moment)
966        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
967          a pointer to the launched InstrumentEditor object
968        - added optional 3rd party user data parameter for following
969          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
970          InstrumentEditor::Launch(),
971          InstrumentManager::LaunchInstrumentEditor()
972        - theoretical fix: made SynchronizedConfig follow C++0x memory
973          model more strictly
974        - fixes for using large audio device buffers
975        - Windows: add the installation directory to the DLL search path
976          when loading an editor plugin (solves problems with VST and
977          gigedit on systems with other GTK versions installed)
978        - updated linuxsampler man page
979    
980      * audio driver:
981        - removed the nonsense audio channel constraint (which was hard coded to
982          max. 100 audio channels) for most audio drivers
983        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
984          opposed to the LSCP specs
985        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
986          reflected the wrong value
987        - fixed a memory management bug in ASIO driver
988        - Makefile fix: JACK_CFLAGS wasn't used
989        - JACK: use jack_client_open instead of the deprecated
990          jack_client_new
991        - added (experimental) CoreAudio driver
992        - applied old fixes to the ASIO driver that were included in the
993          previous binary release but accidentally never committed to CVS
994          (fixes #117)
995        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
996          win64)
997        - VST: added support for sample rate and buffer size changes
998        - VST: close editor (Fantasia) when the VST is removed
999        - VST: avoid opening Fantasia more than once for each VST instance
1000        - VST: export main function as "main" on Linux too (fix for
1001          energyXT)
1002        - VST: changed number of output channels from one stereo to 16
1003          stereo
1004        - added channel routing, fxsends and midi maps to the settings
1005          stored in the plugin state
1006        - performance optimization of AudioChannel::MixTo() and
1007          AudioChannel::CopyTo() methods using GCC vector exensions
1008          (if available)
1009        - ASIO fixes: avoid initializing the device twice, avoid throwing
1010          exception when getting parameters from a disconnected device
1011    
1012      * MIDI driver:
1013        - added JACK MIDI driver
1014        - dispatch bank select as ordinary CC as well, the user might seriously
1015          want to (mis)use it for some purpose ("fixed" in all current MIDI
1016          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
1017        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
1018          CoreMidi or AU
1019        - fixed mingw-w64 compilation error in MME driver
1020        - made program change handling in MIDI thread real-time safe by
1021          moving the logic to a non-RT thread
1022        - fixed minor memory leak in ALSA driver
1023    
1024      * instruments database:
1025        - avoid time consuming samples scanning when adding instruments
1026          to the instruments database
1027        - added support for handling lost files in the instruments database
1028        - Implemented option for adding instruments in separate directories
1029          in the instruments database
1030          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
1031        - work-around for missing fnmatch function on Windows to make
1032          instrument database compilable
1033        - added instrument database support on Windows
1034          works with both standalone mode and VST plugin.
1035          the instruments DB file is located in
1036          %USERPROFILE%\.linuxsampler\instruments.db which allows different
1037          databases for each windows user
1038          if no DB is present it automatically creates the .linuxsampler subdir
1039          and then creates an empty DB
1040        - fixed recursive import, which was broken on Windows
1041    
1042      * Gigasampler format engine:
1043        - fixed a memory leak that could happen when a channel was deleted
1044          while notes were playing
1045        - made it possible to load an instrument even if the audio thread
1046          isn't running
1047        - added partial support for the "Controller Triggered" MIDI rule,
1048          enough for piano gigs with pedal noise samples
1049        - minor fix: only mark FX sends as being modified if really the
1050          respective FX send MIDI controller was used
1051        - added support for GM global device volume SysEx message
1052          (can be selected at compile time to either apply globally to the
1053          whole sampler [default] or only to the sampler channels that are
1054          connected to the respective MIDI input port the SysEx message arrived
1055          on)
1056        - bugfix: notes triggered at position 0 in the audio buffer were
1057          sometimes wrongly killed in the same buffer, causing no sound to
1058          be played
1059        - added support for chromatic / drumkit mode Roland GS Sysex message
1060          which is usally used to switch a part between chromatic sounds and
1061          drumkit sounds (as opposed to their common default setting of MIDI
1062          part 10 being a drumkit part and all other ones chromatic parts), in
1063          LS however one can switch between the first 16 MIDI instrument maps
1064          defined for the sampler
1065        - made it possible to create multiple sample channels even if the
1066          audio thread isn't running
1067        - fixed crash when removing channel with active voices (#116)
1068        - bugfix: on sample reference changes (instrument editor), only
1069          un-cache the respective sample if it's really not used by any
1070          sampler engine anymore
1071        - re-cache samples in case they were changed by an instrument editor,
1072          e.g. when a sample was added while playing (#82)
1073        - fixed hanging notes which occured when note-off event had the exact
1074          same time stamp as the voice's note-on event and occured both in the
1075          same audio fragment cycle (fixes bug #112)
1076        - added support for the "fine tune" and "pitch bend range"
1077          instrument-level gig parameters
1078        - fixed minor artifacts in pitch bend handling
1079        - added support for GS Reset SysEx message
1080        - allow gig files to use unlimited downward pitch shifting
1081        - added a limit check for upward pitch shifting
1082        - bugfix: sometimes, when playing a note twice fast, the second
1083          note was silent
1084        - fixed crash happening when a pitch bend event arrived at the
1085          same time a new instrument was loading
1086    
1087      * LSCP server:
1088        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1089          react on MIDI data arriving on certain sampler channels (so far only
1090          Note-On and Note-Off events are sent via this LSCP event)
1091        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1092          react on MIDI data arriving on certain MIDI input devices (so far only
1093          Note-On and Note-Off events are sent via this LSCP event)
1094        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1095          SET DB_INSTRUMENT FILE_PATH
1096        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1097          frontends to send MIDI messages to specific sampler channel
1098        - added two additional fields to GET FILE INSTRUMENT INFO command -
1099          KEY_BINDINGS and KEYSWITCH_BINDINGS
1100        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1101          was incorrect
1102        - Optimized the retrieval of the MIDI instrument mappings
1103        - added new LSCP command "SET VOICES" to globally alter the maximum
1104          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1105          be triggered respectively
1106        - added new LSCP command "SET STREAMS" to globally alter the maximum
1107          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1108          which will be triggered respectively
1109        - bugfix: retry if "select" returns EINTR (this fixes a crash when
1110          a gigedit file dialog is opened)
1111        - close all connections when LSCPServer is deleted
1112        - hard close of all sockets on exit
1113        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1114          driver
1115    
1116      * Bug fixes:
1117        - fixed a crash which occurs when removing a sampler channel waiting
1118          to start instrument loading after another channel
1119        - fixed a crash which occurs when removing a sampler channel with
1120          instrument loading in progress (bug #113)
1121        - fixed termination caused by uncaught exception when adding MIDI
1122          instrument with PERSISTENT load mode
1123        - fixed possible iterator invalidations when resetting the sampler
1124        - fixed memory leaks when issuing the following LSCP commands:
1125          GET AUDIO_OUTPUT_DRIVER INFO
1126          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1127          GET MIDI_INPUT_DRIVER INFO
1128          GET MIDI_INPUT_DRIVER_PARAMETER INFO
1129        - fixed possible compilation error when sqlite is not present
1130        - fixed orphaned pointers when setting maximum voices limit (bug #118)
1131        - fixed crash when changing the audio output device of a sampler
1132          channel with loaded instrument and start playing notes
1133        - fixed endless loop in Engine::SuspendAll() (bug #120)
1134        - fixed a low-level atomic load function that was broken on 64-bit
1135          PowerPC, which probably could cause crashes on that platform
1136        - fixed a memory management error which could cause a crash when a
1137          plugin was unloaded
1138        - bugfix: two private structs had the same name, which could cause
1139          problems if the linker chose the wrong constructor
1140        - fixed low-level ConditionServer usage bug that caused lockups on
1141          Windows
1142    
1143    
1144    Version 0.5.1 (6 December 2007)
1145    
1146      * packaging changes:
1147        - added autoconf checks for pthread library
1148        - added autoconf check for pthread bug found on certain NPTL-enabled
1149          glibc versions (see Gentoo bug report #194076)
1150        - added autoconf checks for MS Windows
1151    
1152      * general changes:
1153        - bugfix: the thread used by an editor plugin didn't die when the
1154          editor closed
1155        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1156          out all the space. operator--() did not apply size_mask after
1157          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1158          order to avoid problems with the _NonVolatileReader functions.
1159        - bugfix: Stream.h: added a missing divide by BytesPerSample in
1160          GetWriteSpace(). Since this function is currently only used in
1161          the stream's qsort() compare function, it didn't trigger any
1162          bugs.
1163        - Resampler.h, Synthesizer.h: cubic interpolation now works in
1164          24bit mode too. Faster method to read 24bit words on little
1165          endian machines (x86): replaced 3 byte reads + shifts with a 1
1166          unaligned 32bit read and shift
1167        - experimental support for MS Windows (MIDI input via MME, AUDIO
1168          output via ASIO)
1169        - made handling of SIGINT signal (Ctrl-C) a bit more robust
1170        - support for monitoring the total number of active disk streams
1171          (new LSCP commands: GET TOTAL_STREAM_COUNT,
1172          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1173    
1174      * AUDIO driver:
1175        - added Windows ASIO low latency audio driver
1176    
1177      * MIDI driver:
1178        - added MME Windows MIDI driver
1179    
1180      * LSCP server:
1181        - added support for Windows style path / filenames, however with
1182          forward slash path separators instead of backslash
1183          (i.e. "C:/foo/bar.gig")
1184        - allow naughty liblscp to send non-string device parameters within
1185          apostrophes as well
1186        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1187          "LIST FILE INSTRUMENTS <file>" and
1188          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1189          about an arbitrary instrument file on the system where the sampler is
1190          running on
1191    
1192    Version 0.5.0 (15 October 2007)
1193    
1194      * packaging changes:
1195        - config.h is not going to be installed along with liblinuxsampler's
1196          API header files anymore
1197        - only the API relevant header (and source) files will be exported to
1198          the Doxygen API documentation (explicitly listed in Doxyfile.in)
1199        - added completely new XCode project files for Mac OSX which is now
1200          capable to execute our autoconf environment, thus no need anymore
1201          to maintain the compile time configuration file (osx/version.h) for
1202          OSX manually (patch by Toshi Nagata)
1203        - fixed buggy boolean --enable-foo / --disable-foo configure script
1204          parameters
1205        - global.h now only covers global definitions that are needed for the
1206          C++ API header files, all implementation internal global definitions
1207          are now in global_private.h
1208        - atomic.h is not exposed to the C++ API anymore
1209        - no need to include config.h anymore for using LS's API header files
1210        - fixed warnings in API doc generation
1211    
1212      * general changes:
1213        - replaced the old, confusing MIDI program change mechanism by a
1214          flexible MIDI instrument mapper which allows to map arbitrary
1215          (MIDI bank, MIDI program) pairs with arbitrary
1216          (engine type, instrument file, file index) triplets which will be
1217          loaded on the respective channel when such MIDI program change
1218          messages arrive, beside that, each entry allows to define a life-time
1219          strategy for the instrument, so the user can define whether the
1220          instrument should i.e. be permanently loaded (to be able to switch
1221          quickly among sounds) or i.e. loaded just on demand when the
1222          respective program change arrives (to safe RAM space), as well as a
1223          global volume factor for each entry, so the user can adjust the volume
1224          dynamic of his mapped instrument collection without having to modify
1225          the instrument files, also one can manage arbitrary amount of such
1226          MIDI instrument maps and assign each sampler channel individually
1227          a certain map, so that i.e. separation of normal instruments and
1228          drumkits is possible
1229        - new notification events for tracking changes to audio/MIDI devices,
1230          MIDI instrument maps, MIDI instruments, FX sends, global volume.
1231        - sampler was limited to load max. 200 instruments in the background
1232          due to a constant size RingBuffer FIFO which is now replaced by a
1233          dynamic (unlimited) size std::list FIFO
1234        - added FX sends, these allow to route audio signals to arbitrary audio
1235          output channels for being processed by external effect processors
1236          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1237          controllers
1238        - global (sampler wide) volume can now be controlled at runtime
1239        - Implemented new, improved notification system
1240        - fixed compilation errors regarding OSX
1241          (patch by Toshi Nagata)
1242        - implemented instruments database
1243        - added support for escape sequences to the instruments database
1244        - added highly experimental support for on-the-fly instrument editing
1245          within the sampler's process (by using instrument editor plugins),
1246          you'll notice the new "Registered instrument editors:" message on
1247          startup, added a new LSCP command:
1248          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1249          to spawn a matching instrument editor for the instrument on the
1250          given sampler channel, the plugin path can be overridden at compile
1251          time with ./configure --enable-plugin-dir=/some/dir
1252        - added experimental code for synchronizing instrument editors hosted
1253          in the sampler's process to safely edit instruments while playing
1254          without a crash (hopefully) by either suspending single regions
1255          wherever possible or if unavoidable whole engine(s)
1256        - fixed several issues in fundamental "Thread" class: set scheduling
1257          policy and priority on thread level, set a minimum stack size for
1258          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1259          threads simply inherited properties of starting thread instead of
1260          setting their own policy and priority
1261        - minor fix in our automatic stack trace mechanism on crashes, the
1262          main process did not wait for the stack trace process to finish
1263          its output
1264        - fixed some minor memory leaks
1265        - reenabled assembly features support, at the moment only for
1266          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1267        - minor assembly fix in x86 features detection (don't use the PIC
1268          register, to avoid relocations in the text segment at runtime)
1269        - POSIX callback functions of Thread.h are hidden
1270    
1271      * MIDI driver:
1272        - dispatch bank select (MSB and LSB) messages
1273    
1274      * audio driver:
1275        - the ALSA audio output driver parameters now reflect the correct
1276          parameter value ranges for the respective selected sound card
1277          (patch by Till Wimmer, a bit fixed and extended)
1278    
1279      * Gigasampler format engine:
1280        - if a filter is used and EG2 finishes before EG1, let the voice
1281          die when EG2 has finished (this fixes a problem with clicks and
1282          voice starvation for some gigs)
1283        - playback is no longer disabled during instrument loading
1284        - all notes playing on a channel that changes its instrument keep
1285          playing with the old instrument until they get a note off
1286          command
1287        - EG fix: a release value of zero could cause noises or crash
1288        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1289        - EG fine tuning: when attack is zero the EG starts at a level
1290          above max sustain level, which means that there is a decay phase
1291          even if sustain is 100%
1292        - more EG fixes: the level could sometimes go below zero and cause
1293          noises or crashes
1294        - minor fix of EGDecay (patch by Toshi Nagata)
1295        - fixed compiler error when --enable-override-filter-type was
1296          supplied to the configure script (fixes #46)
1297        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1298          instead of a fix value
1299        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1300          127 (solo mode) only kill voices if the respective mode really
1301          changed
1302    
1303      * LSCP server:
1304        - fixed compile time error for old Bison versions
1305          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1306        - parser now supports extended ASCII character set
1307          (up to ASCII code 255, i.e. includes now umlauts and accents)
1308        - filename arguments in LSCP commands now allow to use escape
1309          sequences, that is directly literal as one of: \', \", \\, \n, \r,
1310          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1311          code value like \xf2) (fixes bug #24)
1312        - the following LSCP commands now also support escape sequences for at
1313          least one of their text-based parameters (i.e. name, description):
1314          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1315          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1316          "SET DB_INSTRUMENT_DIRECTORY NAME",
1317          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1318          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1319          "FIND DB_INSTRUMENT_DIRECTORIES"
1320        - returns verbose syntax errors (line and column where syntax error
1321          occured, the unexpected character and the actually expected, possible
1322          character(s), the latter only if less than 5 possibilities)
1323        - made sure that LSCP syntax is not affected by gigedit locale
1324          settings
1325        - bugfix regarding strings parameter lists: all comma separated lists
1326          of strings were treated as being one string containing commas
1327          (fixes #57)
1328    
1329      * Bug fixes:
1330        - fixed crash occurring on certain LSCP scripts (Bug 39)
1331        - another thread safety fix for lscp "load engine" and "set
1332          channel audio output device"
1333        - fixed a crash which occurs when reassigning the same engine
1334          on a sampler channel with connected MIDI device
1335        - fixed a crash which occurs when changing the number of ports of a MIDI
1336          device connected to a sampler channel to number less then or equal
1337          to the index of the port to which the sampler channel is connected.
1338        - The previous bindings were not been disconnected when altering
1339          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1340          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1341        - The active stream/voice count statistic was incorrect.
1342        - notification events were not been sent for some sampler
1343          channel changes
1344        - added default min and max values to restrict the number of allowed
1345          audio output channels and MIDI input ports
1346        - the connection to the PCM interface is now closed when destroying
1347          an audio output device
1348        - files with slash in their path or filename could not be loaded
1349    
1350      * test cases:
1351        - updated and fixed (haven't been touched in a while)
1352    
1353    Version 0.4.0 (24 November 2006)
