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

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

527        - fine-tuned the default velocity curve
528        - added support for transpose
529        - fixed crash when using sw_down/up
530        - improved logic for sw_lokey/hikey/up/down/last
531        - added more v1 aliases to parser
532        - reduced memory usage for sfz data
533        - RT-safeness: avoid malloc in audio thread

542        - use loop markers from sample file if loop_start and loop_end are
543          not set in sfz file
544        - implemeted filters. Filter types: lowpass, bandpass, bandreject

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

699          the plugin was loaded a second time (#174)
700        - plugin bugfix: instrument loading hang when the plugin was
701          loaded a second time (this time it's for Linux and Mac, previous
702          similar fix was for Windows)
703        - thread safety fixes for the instrument loading thread
704        - LV2: use the new lv2 package if present
705        - VST: try to open Fantasia automatically on Linux and Mac too (on
706          Linux, the Fantasia jar should be placed in <prefix>/share/java)
707        - VST: fixed crashes on Linux Ardour and EnergyXT
708        - DSSI bugfix: it wasn't possible to change engine type. The MIDI
709          port and audio channel routing for DSSI plugins are now visible.
710        - LV2: use urid and atom extensions instead of deprecated uri-map
711          and event
712        - LV2: lv2 package 1.0 is now required to build the LV2 plugin
713        - LV2: changed number of output channels to 16 stereo, just like
714          the VST and AU plugins
715        - LV2: fixed save/restore of SFZ state (patch by David Robillard)
716        - LV2: made LV2 plugin buildable on Windows and Mac
717        - VST: implemented retrieval and switching of programs using the
718          sampler's internal MIDI instrument mapping system
719    
720      * Instrument editor interface:
721        - Changed instrument editor plugin interface, providing additional
722          informations like the EngineChannel for which the instrument editor was
723          spawned for. This allows the instrument editors to interact more actively
724          with the sampler.
725    
726      * MIDI driver:
727        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
728          the ALSA sequencer client name

730          there is no reason for this limit
731        - MME: fixed memory handling bug found with cppcheck
732        - MME: removed compiler warning
733        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
734          which allows to retrieve the list of CoreMIDI clients / ports and to connect
735          to them a la JACK, via the usual sampler APIs
736        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
737          the driver will automatically connect to other CoreMIDI clients' ports
738          (e.g. external MIDI devices being attached to the Mac)
739        - added support for MIDI note on velocity filter
740        - CoreMIDI: fixed memory deallocation error
741        - Fixed variable underflow in VirtualMidiDevice, which caused graphical
742          virtual keyboards in frontends / instrument editors being stuck.
743        - Bugfix in VirtualMidiDevice: process note on with velocity 0 as note off.
744        - Implemented missing handling of MIDI "running status".
745        - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
746        - MME bugfix: driver wasn't closed properly
747        - CoreMIDI: automatically connect to all input sources by default (driver
748          parameter "AUTO_BIND").
749        - CoreMIDI: fixed auto bind feature to CoreMIDI ports that go online
750        - CoreMIDI: fixed minor memory leak
751    
752      * audio driver:
753        - ASIO driver fixes for newer gcc versions (fix from PortAudio)
754        - JACK audio: react on sample rate changes.

757          RT context.
758        - ASIO driver: removed compiler warnings
759        - CoreAudio: fixed minor error handling bug
760        - ASIO driver: be more verbose when no ASIO card could be found (fixes #203)
761        - JACK audio: return the JACK server's current sample rate as default value
762          for audio device parameter "SAMPLERATE" (fixes #166).
763    
764      * LSCP server:
765        - added support for sending MIDI CC messages via LSCP command
766          "SEND CHANNEL MIDI_DATA CC <sampler-chan> <ctrl> <val>"

800        - provide comprehensive error messages on LSCP syntax errors
801          (suggesting expected next non-terminal symbols)
802        - Fixed client connection not being closed after network errors.
803    
804      * LSCP shell:
805        - Added support for auto correction of obvious and trivial syntax mistakes.

807        - Show currently available auto completion while typing.
808        - Added support for browsing command history with up / down keys.
809        - Show all possible next symbols immediately right to the current command
810          line while typing (no double tab required for this feature, as it would
811          be the case in other shells).
812        - Added support for moving cursor left/right with arrow keys.
813        - Added support for built-in LSCP reference documentation, which will
814          automatically show the relevant LSCP reference section on screen as soon
815          as one specific LSCP command was detected while typing on the command
816          line.
817

834          or no argument).
835        - Implemented built-in script function "set_controller()".
836        - Added extended script VM for the Gigasampler/GigaStudio format sampler
837          engine, which extends the general instrument script VM with Giga format
838          specific variables and functions.
839        - Giga format scripts: added built-in script int constant variables
840          $GIG_DIM_CHANNEL, $GIG_DIM_LAYER, $GIG_DIM_VELOCITY, $GIG_DIM_AFTERTOUCH,

870        - minor valgrind fixes
871        - fixed crash which occurred when changing an already deployed sampler
872          channel to a different engine type
873        - fixed crash when deleting a sampler channel or changing engine
874          type while an instrument load was in progress
875        - bugfix: playing a note while changing the instrument could cause
876          a crash, or give "Handing back unknown region" error messages
877        - bugfix: calling SET VOICES (which Fantasia does on start and
878          refresh) could cause instruments to be unloaded
879        - Mac OS X: fixed name collision of enum in EffectControl and
880          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
881        - Mac OS X: fixed hanging threads
882        - Windows: disabled the previous thread fix on non-Mac systems, as
883          it caused hanging threads on Windows
884        - Fixed possible crashes due to corrupted MIDI/audio device list
885          after MIDI/audio device creation failure
886        - When creating MIDI instrument map entries with "PERSISTENT" type, the
887          instruments were uselessly precached with zero samples, however it still
888          took the full preloading time and on 1st program change the respective
889          instrument was completely reloaded again.
890        - fixed handling of rapid bank select and program change messages
891          sent to the same sampler channel (patch from the Open Octave
892          project, slightly adjusted)
893        - fixed crash when trying to create an effect instance with controls
894          which min and/or max values depend on the sample rate

896        - bugfix: LADSPA_PATH was not evaluated correctly when containing
897          multiple paths (#165)
898        - thread safety fixes for the instrument loading thread
899        - bugfix: instrument loading crashed for sfz and sf2 in Ardour
900          (#176)

902        - sfz/sf2 engine: fixed crash when using small audio fragment size
903        - Mac OS X: fixed crash when unloading plugin on 10.7 and later
904        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
905          introduced in previous fix)
906        - fixed crash when a channel received a program change while
907          playing a note in a key group
908        - fixed erroneous error message piping in VoiceBase.h
909          (labelled "Disk stream not available in time")
910        - Update effects on sample rate & period size changes (to avoid
911          crashes and noise on such transitions).
912        - ignore missing LADSPA paths without ignoring valid LADSPA paths
913          (fixes #208)
914        - Fixed bug in LSCP grammar definition which caused a statement like
915          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
916          practically irrelevant, however it caused problems with the new LSCP
917          shell's auto completion feature).
918        - Fixed MIDI program change messages being ignored if quickly executed
919          after each other (fixes #231).
920    
921    Version 1.0.0 (31 July 2009)
922    
923      * packaging changes:
924        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
925          causing e.g. the libgig test to fail when
926          "./configure --disable-jack-driver" was used
927          (patch by Alexis Ballier)
928        - fixed compilation with gcc 4.3
929        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
930        - fixed configure so it detects x86_64 (#107)
931        - fixes for building with newer MinGW versions
932        - fix for building with bison 2.4 (#111)
933        - fixed building with libgig installed in a non-standard directory
934        - minor fix in configure for mmsystem.h detection on MinGW
935        - Windows: look for editor plugins and Fantasia using base
936          directory of liblinuxsampler dll (look in the same directory and one
937          directory above)
938        - configure script fix: removed unconditional use of SSE
939        - fixed building with sqlite installed in a non-standard directory
940        - when cross-compiling, don't try to create instruments.db
941        - fix for new mingw-w64 version, which has usleep
942    
943      * general changes:
944        - bugfix: on some POSIX systems instrument editor plugins refused to
945          load as we used a non-portable Linux specific struct field
946          (fixes bug #70, patch by Ronald Baljeu)
947        - fixed endless loop which occured when loading an instrument editor
948          plugin DLL on Windows systems failed
949        - fixed memory leaks that occurred when liblinuxsampler was unloaded
950        - optimized the SynchronizedConfig class so it doesn't wait
951          unnecessarily long after an update
952        - added support for notifying instrument editors on note-on / note-off
953          events (e.g. to highlight the pressed keys on the virtual keyboard
954          of gigedit)
955        - added support for triggering notes by instrument editors (see above)
956        - be verbose on DLL load errors (on Linux)
957        - fixed di-harmonic triangle LFO implementation (this LFO implementation
958          is only used by very few systems, most pick the int math
959          implementation, which is usually faster)
960        - fixes for audio drivers with varying buffer sizes
961        - experimental support for running LinuxSampler as a DSSI, LV2 and
962          VST plugin
963        - notification events for stream/voice count statistics are now sent
964          only when there are actual changes
965        - added memory ordering constraints to improve stability on
966          multi-core and multi-cpu systems
967        - maximum voices and disk streams can now be altered at runtime
968        - fixed CPU feature detection on x86_64 (maybe fixes #108)
969        - automatic stacktrace mechanism is now turned off by default and can
970          be switched on by command line option "--stacktrace" (the automatic
971          stacktrace mechanism seems to be broken on most systems at the moment)
972        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
973          a pointer to the launched InstrumentEditor object
974        - added optional 3rd party user data parameter for following
975          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
976          InstrumentEditor::Launch(),
977          InstrumentManager::LaunchInstrumentEditor()
978        - theoretical fix: made SynchronizedConfig follow C++0x memory
979          model more strictly
980        - fixes for using large audio device buffers
981        - Windows: add the installation directory to the DLL search path
982          when loading an editor plugin (solves problems with VST and
983          gigedit on systems with other GTK versions installed)
984        - updated linuxsampler man page
985    
986      * audio driver:
987        - removed the nonsense audio channel constraint (which was hard coded to
988          max. 100 audio channels) for most audio drivers
989        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
990          opposed to the LSCP specs
991        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
992          reflected the wrong value
993        - fixed a memory management bug in ASIO driver
994        - Makefile fix: JACK_CFLAGS wasn't used
995        - JACK: use jack_client_open instead of the deprecated
996          jack_client_new
997        - added (experimental) CoreAudio driver
998        - applied old fixes to the ASIO driver that were included in the
999          previous binary release but accidentally never committed to CVS
1000          (fixes #117)
1001        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
1002          win64)
1003        - VST: added support for sample rate and buffer size changes
1004        - VST: close editor (Fantasia) when the VST is removed
1005        - VST: avoid opening Fantasia more than once for each VST instance
1006        - VST: export main function as "main" on Linux too (fix for
1007          energyXT)
1008        - VST: changed number of output channels from one stereo to 16
1009          stereo
1010        - added channel routing, fxsends and midi maps to the settings
1011          stored in the plugin state
1012        - performance optimization of AudioChannel::MixTo() and
1013          AudioChannel::CopyTo() methods using GCC vector exensions
1014          (if available)
1015        - ASIO fixes: avoid initializing the device twice, avoid throwing
1016          exception when getting parameters from a disconnected device
1017    
1018      * MIDI driver:
1019        - added JACK MIDI driver
1020        - dispatch bank select as ordinary CC as well, the user might seriously
1021          want to (mis)use it for some purpose ("fixed" in all current MIDI
1022          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
1023        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
1024          CoreMidi or AU
1025        - fixed mingw-w64 compilation error in MME driver
1026        - made program change handling in MIDI thread real-time safe by
1027          moving the logic to a non-RT thread
1028        - fixed minor memory leak in ALSA driver
1029    
1030      * instruments database:
1031        - avoid time consuming samples scanning when adding instruments
1032          to the instruments database
1033        - added support for handling lost files in the instruments database
1034        - Implemented option for adding instruments in separate directories
1035          in the instruments database
1036          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
1037        - work-around for missing fnmatch function on Windows to make
1038          instrument database compilable
1039        - added instrument database support on Windows
1040          works with both standalone mode and VST plugin.
1041          the instruments DB file is located in
1042          %USERPROFILE%\.linuxsampler\instruments.db which allows different
1043          databases for each windows user
1044          if no DB is present it automatically creates the .linuxsampler subdir
1045          and then creates an empty DB
1046        - fixed recursive import, which was broken on Windows
1047    
1048      * Gigasampler format engine:
1049        - fixed a memory leak that could happen when a channel was deleted
1050          while notes were playing
1051        - made it possible to load an instrument even if the audio thread
1052          isn't running
1053        - added partial support for the "Controller Triggered" MIDI rule,
1054          enough for piano gigs with pedal noise samples
1055        - minor fix: only mark FX sends as being modified if really the
1056          respective FX send MIDI controller was used
1057        - added support for GM global device volume SysEx message
1058          (can be selected at compile time to either apply globally to the
1059          whole sampler [default] or only to the sampler channels that are
1060          connected to the respective MIDI input port the SysEx message arrived
1061          on)
1062        - bugfix: notes triggered at position 0 in the audio buffer were
1063          sometimes wrongly killed in the same buffer, causing no sound to
1064          be played
1065        - added support for chromatic / drumkit mode Roland GS Sysex message
1066          which is usally used to switch a part between chromatic sounds and
1067          drumkit sounds (as opposed to their common default setting of MIDI
1068          part 10 being a drumkit part and all other ones chromatic parts), in
1069          LS however one can switch between the first 16 MIDI instrument maps
1070          defined for the sampler
1071        - made it possible to create multiple sample channels even if the
1072          audio thread isn't running
1073        - fixed crash when removing channel with active voices (#116)
1074        - bugfix: on sample reference changes (instrument editor), only
1075          un-cache the respective sample if it's really not used by any
1076          sampler engine anymore
1077        - re-cache samples in case they were changed by an instrument editor,
1078          e.g. when a sample was added while playing (#82)
1079        - fixed hanging notes which occured when note-off event had the exact
1080          same time stamp as the voice's note-on event and occured both in the
1081          same audio fragment cycle (fixes bug #112)
1082        - added support for the "fine tune" and "pitch bend range"
1083          instrument-level gig parameters
1084        - fixed minor artifacts in pitch bend handling
1085        - added support for GS Reset SysEx message
1086        - allow gig files to use unlimited downward pitch shifting
1087        - added a limit check for upward pitch shifting
1088        - bugfix: sometimes, when playing a note twice fast, the second
1089          note was silent
1090        - fixed crash happening when a pitch bend event arrived at the
1091          same time a new instrument was loading
1092    
1093      * LSCP server:
1094        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1095          react on MIDI data arriving on certain sampler channels (so far only
1096          Note-On and Note-Off events are sent via this LSCP event)
1097        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1098          react on MIDI data arriving on certain MIDI input devices (so far only
1099          Note-On and Note-Off events are sent via this LSCP event)
1100        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1101          SET DB_INSTRUMENT FILE_PATH
1102        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1103          frontends to send MIDI messages to specific sampler channel
1104        - added two additional fields to GET FILE INSTRUMENT INFO command -
1105          KEY_BINDINGS and KEYSWITCH_BINDINGS
1106        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1107          was incorrect
1108        - Optimized the retrieval of the MIDI instrument mappings
1109        - added new LSCP command "SET VOICES" to globally alter the maximum
1110          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1111          be triggered respectively
1112        - added new LSCP command "SET STREAMS" to globally alter the maximum
1113          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1114          which will be triggered respectively
1115        - bugfix: retry if "select" returns EINTR (this fixes a crash when
1116          a gigedit file dialog is opened)
1117        - close all connections when LSCPServer is deleted
1118        - hard close of all sockets on exit
1119        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1120          driver
1121    
1122      * Bug fixes:
1123        - fixed a crash which occurs when removing a sampler channel waiting
1124          to start instrument loading after another channel
1125        - fixed a crash which occurs when removing a sampler channel with
1126          instrument loading in progress (bug #113)
1127        - fixed termination caused by uncaught exception when adding MIDI
1128          instrument with PERSISTENT load mode
1129        - fixed possible iterator invalidations when resetting the sampler
1130        - fixed memory leaks when issuing the following LSCP commands:
1131          GET AUDIO_OUTPUT_DRIVER INFO
1132          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1133          GET MIDI_INPUT_DRIVER INFO
1134          GET MIDI_INPUT_DRIVER_PARAMETER INFO
1135        - fixed possible compilation error when sqlite is not present
1136        - fixed orphaned pointers when setting maximum voices limit (bug #118)
1137        - fixed crash when changing the audio output device of a sampler
1138          channel with loaded instrument and start playing notes
1139        - fixed endless loop in Engine::SuspendAll() (bug #120)
1140        - fixed a low-level atomic load function that was broken on 64-bit
1141          PowerPC, which probably could cause crashes on that platform
1142        - fixed a memory management error which could cause a crash when a
1143          plugin was unloaded
1144        - bugfix: two private structs had the same name, which could cause
1145          problems if the linker chose the wrong constructor
1146        - fixed low-level ConditionServer usage bug that caused lockups on
1147          Windows

1166                GetWriteSpace(). Since this function is currently only used in
1167          the stream's qsort() compare function, it didn't trigger any
1168          bugs.
1169        - Resampler.h, Synthesizer.h: cubic interpolation now works in
1170          24bit mode too. Faster method to read 24bit words on little

1172          unaligned 32bit read and shift
1173        - experimental support for MS Windows (MIDI input via MME, AUDIO
1174          output via ASIO)
