* NKSP script editor API: Added support for detecting standard unit tokens
  and their potential metric prefix token.

1 schoenebeck 3548 Version SVN trunk (?)
2    
3     * general changes:
4     - Fixed compiler error in Pool.h.
5 schoenebeck 3557 - 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 schoenebeck 3550
11 schoenebeck 3551 * Real-time instrument scripts:
12     - Added method ScriptVM::setExitResultEnabled() which allows to
13     explicitly enable the built-in exit() function to optionally accept
14     one function argument; the value of the passed exit() function
15     argument will then become available by calling
16     VMExecContext::exitResult() after script execution.
17 schoenebeck 3557 - 64 bit support for NKSP integer scripts variables (declare $foo).
18 schoenebeck 3561 - Variable names, function names and preprocessor condition names must start
19     with a regular character (a-z or A-Z); starting them with a digit or
20     underscore is not allowed.
21     - NKSP parser fix: equal comparison operator "=" and not equal comparison
22     operator "#" must only accept integer operands.
23     - NKSP language: Implemented support for standard units like Hertz, seconds,
24     Bel including support for metric unit prefixes; so one can now e.g.
25     conveniently use numbers in scripts like "5us" meaning "5 microseconds",
26     or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
27     "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
28     - NKSP language: Introduced "final" operator "!" which is specifically
29     intended for synthesis parameter values to denote that the synthesis
30     parameter value is intended to be the "final" value for that synthesis
31     parameter that should explicitly be used by the engine and thus causing
32     the sampler engine to ignore all other modulation sources for the same
33     synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
34     variable or formula with this new "!" operator the expression is marked as
35     being "final".
36 schoenebeck 3562 - NKSP script editor API: Added support for detecting standard unit tokens
37     and their potential metric prefix token.
38 schoenebeck 3551
39 schoenebeck 3550 * test cases:
40 schoenebeck 3548 - Fixed compiler errors in test cases.
41     - Updated README for how to compile & run test cases.
42     - Updated test case
43     MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
44     expected behaviour of the Mutex class implementation (recursive
45     mutex type).
46 schoenebeck 3551 - Added test cases for NKSP core language aspects and core built-in
47     functions.
48 schoenebeck 3552 - Fixed thread tests segfaulting on Linux.
49 schoenebeck 3548
50 schoenebeck 3537 Version 2.1.1 (27 Jul 2019)
51 schoenebeck 3381
52     * Real-time instrument scripts:
53     - Fixed behavior of built-in NKSP functions change_sustain(),
54     change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
55     and change_cutoff_release().
56    
57 schoenebeck 3444 * general changes:
58     - Only play release trigger samples on sustain pedal up if this behaviour
59     was explicitly requested by the instrument (otherwise only on note-off).
60 persson 3455 - Fixed compiler warnings.
61     - Fixed compilation error when cross-compiling to Mac.
62 schoenebeck 3501 - FX Sends: Provide more useful error messages on routing problems
63     (see bug #169).
64     - LSCP doc: Be more clear describing the two distinct approaches
65     of using external vs. internal effects (see bug #169).
66 schoenebeck 3514 - "optional" class: Fixed comparison operators.
67 schoenebeck 3444
68 schoenebeck 3448 * Gigasampler/GigaStudio format engine:
69     - Format extension: If requested by instrument then don't play release
70     trigger sample on note-off events.
71    
72 schoenebeck 3487 * SFZ format engine:
73     - Fixed memory leak when releasing samples
74     (fixes bug #307, patch by Jacek Roszkowski)
75 schoenebeck 3492 - Fixed potential crash when a sample is shared by more than one region
76     (fixes bug #308, patch by Jacek Roszkowski).
77 schoenebeck 3497 - Opcode 'sample': Added support for built-in sample '*silence'
78     (fixes bug #310, patch by Jacek Roszkowski).
79 schoenebeck 3487
80 schoenebeck 3372 Version 2.1.0 (25 Nov 2017)
81 persson 2837
82 persson 2856 * SFZ format engine:
83     - added support for <global>, <master> and #define (patch by Alby M)
84 schoenebeck 3082 - Removed code duplication in SFZ file loading code.
85     - Added support for sfz extension opcode 'script' which may be used to
86     load real-time instrument script file (NKSP script language).
87 schoenebeck 3095 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
88 schoenebeck 3100 - Fixed unintended volume fade-in of voices under certain conditions.
89 persson 3291 - sfz parser: allow missing space between header and opcode
90 persson 2856
91 schoenebeck 3188 * Gigasampler/GigaStudio format engine:
92 schoenebeck 3072 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
93     cutoff settings.
94 schoenebeck 3302 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
95     all if an up-pitch of more than 40 semi tones was requested (I don't
96     think there is any stock gig sound that requires this behavior to
97     resemble its original sound).
98 schoenebeck 3328 - Added support for controlling whether the individual EGADSR stages may
99     be aborted (as LinuxSampler extension to the original GigaStudio 4
100     format).
101 schoenebeck 3072
102 persson 2837 * general changes:
103     - fixed printf type errors (mostly in debug messages)
104 persson 2840 - use unique_ptr instead of auto_ptr when building with C++11
105 schoenebeck 2871 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
106     allowing to sort data efficiently in real-time safe manner.
107     - RTList class: added methods for moving/inserting elements to arbitrary
108     position within a list.
109     - RTList class: added method fromPtr() for creating an Iterator object from
110     a raw element pointer.
111     - Attempt to partly fix resetting engine channels vs. resetting engine, an
112     overall cleanup of the Reset*(), ConnectAudioDevice(),
113     DisconnectAudioDevice() API methods would still be desirable though,
114     because the current situation is still inconsistent and error prone.
115 schoenebeck 2879 - Active voices are now internally grouped to "Note" objects, instead of
116     being directly assigned to a keyboard key. This allows more fine graded
117     processing of voices, which is i.e. required for certain instrument
118     script features.
119 schoenebeck 2927 - Fix: Release trigger voices were not spawned on sustain pedal up
120     (CC #64) events.
121     - Fix: Release trigger voices can now also distinguish correctly between
122     note-off and sustain pedal up events.
123 schoenebeck 2963 - All engines: Increased ramp speed of volume smoother and pan smoother
124     (while slow rate of crossfade smoother is preserved) to allow quick
125     volume and pan changes by instrument scripts for instance.
126 schoenebeck 3015 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
127     properly and thus were ignored for certain uses.
128 schoenebeck 3018 - Added new C++ API method
129     VirtualMidiDevice::SendChannelPressureToSampler().
130 persson 3020 - windows, 32-bit: fixed potential crashes by making sure the stack in
131     sub threads is 16-byte aligned
132 schoenebeck 3054 - fixed numerous compiler warnings
133 schoenebeck 3205 - Fixed invalid (note-on) event ID being assigned to new Note objects.
134 schoenebeck 3290 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
135     fixes potential undefined behavior.
136 schoenebeck 3306 - Fixed Note object leak when triggering notes on keys which did not
137     have a valid sample mapped (fixes bug #252).
138     - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
139 schoenebeck 3354 - linuxsampler binary fix: option --create-instruments-db ignored
140     subsequent optional argument due to glibc's implementation oddity
141     which expects a "=" sign, but no space between them.
142 persson 2837
143 schoenebeck 2866 * packaging changes:
144     - removed unnecessary dependency to libuuid
145     (originated by libgig's usage of it)
146 schoenebeck 2884 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
147     auto detect whether it (sh/c)ould output its messages in color.
148 schoenebeck 3352 - Debian: Fixed packaging error about invalid "Source-Version"
149     substitution variable.
150     - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
151 schoenebeck 3354 - Debian: Added build dependency to libsqlite3-dev for building
152     linuxsampler with instruments DB support.
153 schoenebeck 2866
154 schoenebeck 2871 * Real-time instrument scripts:
155     - Implemented scheduler for delayed MIDI events and for suspended scripts.
156     - Built-in script function "wait()": implemented support for function's
157     "duration-us" argument, thus scripts using this function are now
158     correctly resumed after the requested amount of microseconds.
159     - Built-in script function "play_note()": implemented support for
160     function's "duration-us" argument, thus notes triggered with this
161     argument are now correctly released after the requested amount of
162     microseconds.
163     - Fix: script events were not cleared when engine channel was reset,
164     potentially causing undefined behavior.
165     - Fixed crash which happened when trying to reference an undeclared
166     variable.
167 schoenebeck 2879 - Built-in script function "play_note()": Added support for passing
168     special value -1 for "duration-us" argument, which will cause the
169     triggered note to be released once the original note was released.
170 schoenebeck 2885 - Instrument script classes now exported with the liblinuxsampler C++ API.
171     - Added new API method ScriptVM::syntaxHighlighting() which provides
172     a convenient syntax highlighting backend for external instrument
173     script editor applications.
174 schoenebeck 2889 - Added new C++ API class "ScriptVMFactory".
175     - Extended parser issues to provide not only first line and first
176     column, but also last line and last column of issue (thus marking
177     the precise span of the issue within the source code).
178 schoenebeck 2902 - Reload script automatically after being modified by an instrument
179     editor.
180 schoenebeck 2911 - NKSP language grammar correction: allow empty event handler bodies
181     like "on note end on".

186     - Implemented built-in script function "change_reso()".
187     - Implemented built-in script function "event_status()".
188     - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
189     "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
190     "event_status()" function.
191     - NKSP language: Added support for bitwise operators ".or.", ".and."
192     and ".not.".
193     - NKSP language scanner: Fixed IDs matching to require at least one
194     character (i.e. when matching function names or variable names).
195     - NKSP language scanner: disabled unusued rules.
196 schoenebeck 2938 - Fixed behavior of play_note() and note_off() functions which must
197     be distinguished engine internally from "real" MIDI note on/off
198     events in order to avoid misbehaviors like hanging notes.
199 schoenebeck 2942 - Implemented built-in script variable "$KSP_TIMER".
200     - Implemented built-in script variable "$NKSP_REAL_TIMER".
201     - Implemented built-in script variable "$NKSP_PERF_TIMER".
202     - Implemented built-in script variable "$ENGINE_UPTIME".
203 schoenebeck 2945 - Implemented built-in script function "inc()".
204     - Implemented built-in script function "dec()".
205     - NKSP language fix: division expressions were evaluated too often.
206     - NKSP language fix: string concatenation operator was right
207     associative instead of left (to right).
208 schoenebeck 2947 - NKSP language correction: allow empty statements in entire language
209     (i.e. "if end if").
210 schoenebeck 2948 - Implemented built-in script function "stop_wait()".
211     - Implemented built-in script variable "$NI_CALLBACK_ID".
212     - Implemented built-in script variable "$NI_CALLBACK_TYPE".
213     - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
214     - Added support for read-only built-in variables (respectively
215     handled by the script parser).
216     - Added built-in script constant "$NI_CB_TYPE_INIT".
217     - Added built-in script constant "$NI_CB_TYPE_NOTE".
218     - Added built-in script constant "$NI_CB_TYPE_RELEASE".
219     - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".

222     - Implemented built-in script function "change_decay()".
223     - Implemented built-in script function "change_release()".
224 schoenebeck 2962 - Fixed all change_*() built-in script functions to apply their
225     synthesis parameter changes immediately in case the respective note
226     was triggered at the same time, instead of scheduling the parameter
227     change, especially because it would cause some parameter types's
228     changes either to be ramped (i.e. change_vol()) or other types even
229     to have not effect at all (i.e. change_attack()).
230 schoenebeck 2965 - Implemented built-in script function "sh_left()".
231     - Implemented built-in script function "sh_right()".
232 schoenebeck 2970 - Implemented built-in script function "min()".
233     - Implemented built-in script function "max()".
234 schoenebeck 2972 - NKSP Fix: "init" event handler was not always executed when a script
235     was loaded.
236     - NKSP built-in wait() script function: abort script execution if
237     a negative or zero wait time was passed as argument (since this is
238     a common indication of a bug either of the script or even of the
239     engine, which could lead to RT instability or even worse).
240 schoenebeck 2974 - ScriptVM: Implemented automatic suspension of RT safety
241     threatening scripts.
242 schoenebeck 3008 - Provide more user friendly error messages on syntax errors.
243 schoenebeck 3013 - Fixed NKSP parser warning "Not a statement" when assigning an
244     initializer list to an array variable.
245 schoenebeck 3073 - Implemented built-in script array variable "%ALL_EVENTS".
246 schoenebeck 3076 - Implemented built-in script function "in_range()".

250     - Implemented built-in script function "change_pitch_lfo_freq()".
251 schoenebeck 3188 - Implemented built-in script function "change_vol_time()".
252     - Implemented built-in script function "change_tune_time()".
253     - Implemented built-in script function "fade_in()".
254     - Implemented built-in script function "fade_out()".
255     - Fixed acceptance of wrong data type of parameters passed to built-in
256     script functions "change_vol()", "change_tune()", "change_pan()",
257     "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
258     "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
259     "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
260 schoenebeck 3193 - Added built-in script function "get_event_par()" and implemented some
261     of its possible parameter selections.
262     - Added built-in script function "set_event_par()" and implemented some
263     of its possible parameter selections.
264 schoenebeck 3205 - Fixed a bunch of scheduler time related bugs.
265 schoenebeck 3207 - Fixed polyphonic variables not being reset to zero after usage.
266 schoenebeck 3212 - Built-in "ignore_event()" function: argument is now optional, like with
267     built-in function "ignore_controller()".
268 schoenebeck 3214 - Implemented built-in script function "change_velo()".
269     - Implemented built-in script function "change_note()".
270 schoenebeck 3218 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
271     intuitive behavior if used in combination with "change_vol_time()" or
272     "change_tune_time()" respectively: now tuning/volume changes are only
273     assigned (without delay) immediately to a new note if the respective
274     timing function has not been called before, otherwise the volume/tuning
275     changes are automatically faded (before, only the event's time stamp was
276     relevant).
277 schoenebeck 3221 - Implemented built-in script function "array_equal()".
278     - Implemented built-in script function "search()".
279     - Implemented built-in script function "sort()".
280     - NKSP Fix: Never suspend "init" event handlers.
281 schoenebeck 3228 - Implemented built-in script function "same_region()" (currently only
282     available for gig format engine).
283 schoenebeck 3246 - Added built-in script constant "$NKSP_LINEAR".
284     - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
285     - Implemented built-in script function "change_vol_curve()".
286     - Implemented built-in script function "change_tune_curve()".
287 schoenebeck 3251 - built-in "play_note()" function now supports a sample playback start
288     offset with argument 3, where special value -1 means to use the regular
289     sample offset as defined by the instrument file.
290 schoenebeck 3253 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
291     - Built-in variable $EVENT_NOTE is now a read-only variable.
292     - Built-in variable $EVENT_VELOCITY is now a read-only variable.
293     - built-in "play_note()" function now accepts -2 for its fourth argument
294     (note duration) which means the life time of the note shall be sticked
295     to the requested note number of argument 1.
296     - Fix: built-in "play_note()" function now returns 0 as result value if
297     -1 was passed for its fourth argument (note duration) and the respective
298     parent note is already gone.
299 schoenebeck 3255 - Implemented built-in script function "change_play_pos()".
300 schoenebeck 3257 - NKSP language: Added support for user declared const array variables.
301     - NKSP language: Raise parser warning if array variable is accessed with
302     an index that exceeds the array's size.

307     another script handler by passing its callback ID.
308 schoenebeck 3283 - Fixed potential memory access bug and potential undefined behavior of
309     "init" event handlers.
310 schoenebeck 3285 - Print a time stamp along to each call of built-in function "message()".
311     - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
312     to retrieve all code blocks filtered out by the preprocessor.
313 schoenebeck 3293 - Added built-in script function "fork()".
314     - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
315     - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
316     - Fixed potential crash when accessing dynamic built-in array variables.
317 schoenebeck 3296 - Added built-in script function "callback_status()".
318     - Added built-in constant $CALLBACK_STATUS_TERMINATED.
319     - Added built-in constant $CALLBACK_STATUS_QUEUE.
320     - Added built-in constant $CALLBACK_STATUS_RUNNING.
321 schoenebeck 3303 - Removed max. value limitation of built-in functions "change_attack()",
322     "change_decay()" and "change_release()" to i.e. allow passing 2000000
323     for doubling the respective time.
324 schoenebeck 3308 - NKSP script editor syntax highlighting API: Fixed app termination due
325     to a lexer start condition stack underrun.
326     - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
327     USE_CODE_IF_NOT() preprocessor statements.
328 schoenebeck 3311 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
329     can be set to disable all subsequent built-in "message()" function calls
330     on preprocessor level.
331 schoenebeck 3316 - Implemented built-in script function "change_sustain()".
332 schoenebeck 3332 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
333     to avoid the editor app to crash on ill-formed text input.
334 schoenebeck 3335 - Added built-in script function "change_pan_time()".
335     - Added built-in script function "change_pan_curve()".

350     - Added support for scanning Sound Font (.sf2) files.
351 schoenebeck 3101 - Fixed undefined DB transaction behavior.

392 persson 2382
393 persson 2086 * general changes:
394 iliev 2012 - Refactoring: moved the independent code from
395     the Gigasampler format engine to base classes
396 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
397     respective profiling code is currently broken
398 schoenebeck 2053 - Introduced support for optional environment variable
399     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
400     where the sampler shall look for instrument editor plugins
401     (patch by Luis Garrido, slightly modified).
402 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
403     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
404     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
405     note (in this implementation of the sampler its simply hard routed to
406     the 1st effect send of the sampler channel, no matter what the actual
407     effect type is)
408     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
409     note (in this implementation of the sampler its simply hard routed to
410     the 2nd effect send of the sampler channel, no matter what the actual
411     effect type is)
412 schoenebeck 2124 - implemented support for internal LADSPA effects
413 schoenebeck 2140 - raised limit of program change queue from 100 to 512
414     (as suggested by Alex Stone)
415 iliev 2223 - implemented sine LFO, pulse LFO and saw LFO
416 iliev 2296 - experimental support for per voice equalization
417 iliev 2306 - added command line option --exec-after-init
418 schoenebeck 2330 - Introduced new C++ API method:
419     EngineChannel::InstrumentFileName(int index)
420     allowing to retrieve the whole list of files used for the loaded
421     instrument on an engine channel (a.k.a. part). Some GigaStudio
422     instruments for example are splitted over several files like
423     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
424 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().
425     - Added new C++ API method Sampler::GetGlobalMaxStreams().
426     - Added new C++ API method Sampler::SetGlobalMaxVoices().
427     - Added new C++ API method Sampler::SetGlobalMaxStreams().
428 schoenebeck 2377 - Various "const" and "restrict" optimizations.
429 persson 2382 - all engines: add pan CC value to instrument pan parameter before
430     applying panning, instead of using two separate pan functions in
431     series (#182)
432 persson 2427 - added a lock guard class for exception safe mutex handling and
433     used it everywhere appropriate
434 schoenebeck 2448 - Immediately apply scale tuning changes to active voices.
435     - Exposed scale tuning to C++ API (along to the already existing standard
436     SysEx way).
437 persson 2452 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
438     and broken for ppc64. (Seq_cst loads and stores are actually not
439     used in LS, so the bug wasn't noticable.)
440     - lsatomic.h: added ARMv7 support
441 schoenebeck 2500 - Added support for multiple MIDI input ports per sampler channel (and
442     added various new C++ methods for this new feature / design change, old
443     C++ API methods for managing SamplerChannel's MIDI inputs are now marked
444     as deprecated but are still there and should provide full behavior
445     backward compatibility).
446     - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
447     unsafe and caused compilation error with clang 2.x).
448 schoenebeck 2506 - Bugfix: only process the latest MIDI program change event.
449 schoenebeck 2515 - Introducing the LSCP shell, which provides convenient control of the
450     sampler from the command line by providing LSCP aware features.
451 schoenebeck 2521 - VirtualMidiDevice: Added support for program change.
452     - VirtualMidiDevice: Added support for bank select (MSB & LSB).
453     - VirtualMidiDevice: Added support for pitch bend.
454 schoenebeck 2559 - Aftertouch: extended API to explicitly handle channel pressure and
455     polyphonic key pressure events (so far polyphonic pressure was not
456     supported at all, and channel pressure was rerouted as CC128 but not
457     used so far).
458 schoenebeck 2594 - Added initial support for real-time instrument scripts. The script VM
459     code is shared by all sampler engine implemementations, however only the
460     gig file format currently provides support for storing instrument scripts
461     (as LinuxSampler extension to the original GigaStudio 4 format).
462 iliev 2012
463 persson 2043 * Gigasampler format engine:
464     - implemented the "round robin keyboard" dimension
465     - fixed round robin and random dimensions for cases when number of

472     filter parameters in each sub fragment)
473     - handle special case when pan parameter in gig file has max or
474     min value
475 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,
476     doesn't sound naturally with a drumkit

662     incorrectly set to two. This caused silence in Cubase 5.
663 persson 2165 - save engine type (gig, sfz or sf2) in plugin state
664     - VST: when opening Fantasia, look for both 32 and 64 bit Java on

696     informations like the EngineChannel for which the instrument editor was
697     spawned for. This allows the instrument editors to interact more actively
698     with the sampler.
699    
700 schoenebeck 1993 * MIDI driver:

887     (fixes #208)
888 schoenebeck 2523 - Fixed bug in LSCP grammar definition which caused a statement like
889     "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
890     practically irrelevant, however it caused problems with the new LSCP
891     shell's auto completion feature).
892 schoenebeck 2672 - Fixed MIDI program change messages being ignored if quickly executed
893     after each other (fixes #231).

945     stacktrace mechanism seems to be broken on most systems at the moment)
946 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
947     a pointer to the launched InstrumentEditor object
948 schoenebeck 1876 - added optional 3rd party user data parameter for following

1012     instrument database compilable
1013 schoenebeck 1930 - added instrument database support on Windows
1014     works with both standalone mode and VST plugin.
1015     the instruments DB file is located in
1016     %USERPROFILE%\.linuxsampler\instruments.db which allows different

1021 iliev 1603
1022 persson 1644 * Gigasampler format engine:

1026     isn't running
1027 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
1028     enough for piano gigs with pedal noise samples

1034     connected to the respective MIDI input port the SysEx message arrived
1035     on)
1036 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
1037     sometimes wrongly killed in the same buffer, causing no sound to
1038     be played
1039 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
1040     which is usally used to switch a part between chromatic sounds and
1041     drumkit sounds (as opposed to their common default setting of MIDI
1042     part 10 being a drumkit part and all other ones chromatic parts), in
1043     LS however one can switch between the first 16 MIDI instrument maps
1044     defined for the sampler
1045 persson 1764 - made it possible to create multiple sample channels even if the

1049     un-cache the respective sample if it's really not used by any
1050     sampler engine anymore
1051     - re-cache samples in case they were changed by an instrument editor,
1052     e.g. when a sample was added while playing (#82)
1053 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
1054     same time stamp as the voice's note-on event and occured both in the
1055     same audio fragment cycle (fixes bug #112)
1056 persson 1858 - added support for the "fine tune" and "pitch bend range"
1057     instrument-level gig parameters
1058     - fixed minor artifacts in pitch bend handling
1059 schoenebeck 1860 - added support for GS Reset SysEx message
1060 persson 1862 - allow gig files to use unlimited downward pitch shifting
1061     - added a limit check for upward pitch shifting
1062 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
1063     note was silent
1064 persson 1923 - fixed crash happening when a pitch bend event arrived at the
1065     same time a new instrument was loading
1066 persson 1644
1067 schoenebeck 1687 * LSCP server:
1068     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1069     react on MIDI data arriving on certain sampler channels (so far only
1070     Note-On and Note-Off events are sent via this LSCP event)
1071 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1072     react on MIDI data arriving on certain MIDI input devices (so far only
1073     Note-On and Note-Off events are sent via this LSCP event)
1074 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1075     SET DB_INSTRUMENT FILE_PATH
1076 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1077     frontends to send MIDI messages to specific sampler channel
1078     - added two additional fields to GET FILE INSTRUMENT INFO command -
1079     KEY_BINDINGS and KEYSWITCH_BINDINGS
1080 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1081     was incorrect
1082 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
1083 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
1084     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1085     be triggered respectively
1086     - added new LSCP command "SET STREAMS" to globally alter the maximum
1087     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1088     which will be triggered respectively
1089 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1090     a gigedit file dialog is opened)
1091 iliev 1848 - close all connections when LSCPServer is deleted
1092 iliev 1882 - hard close of all sockets on exit
1093 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1094     driver
1095 schoenebeck 1687
1096 iliev 1761 * Bug fixes:
1097     - fixed a crash which occurs when removing a sampler channel waiting
1098     to start instrument loading after another channel
1099 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
1100     instrument loading in progress (bug #113)
1101 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
1102     instrument with PERSISTENT load mode
1103 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
1104     - fixed memory leaks when issuing the following LSCP commands:
1105     GET AUDIO_OUTPUT_DRIVER INFO
1106     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1107     GET MIDI_INPUT_DRIVER INFO
1108     GET MIDI_INPUT_DRIVER_PARAMETER INFO

1110 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1111 iliev 1847 - fixed crash when changing the audio output device of a sampler
1112     channel with loaded instrument and start playing notes
1113 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
1114 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
1115     PowerPC, which probably could cause crashes on that platform
1116 persson 1889 - fixed a memory management error which could cause a crash when a
1117     plugin was unloaded
1118 persson 1896 - bugfix: two private structs had the same name, which could cause
1119     problems if the linker chose the wrong constructor
1120 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
1121     Windows
1122 iliev 1761
1123    
1124 schoenebeck 1560 Version 0.5.1 (6 December 2007)
1125 schoenebeck 1454
1126     * packaging changes:
1127     - added autoconf checks for pthread library
1128     - added autoconf check for pthread bug found on certain NPTL-enabled
1129     glibc versions (see Gentoo bug report #194076)
1130 senoner 1502 - added autoconf checks for MS Windows
1131 schoenebeck 1454
1132 persson 1455 * general changes:
1133     - bugfix: the thread used by an editor plugin didn't die when the
1134     editor closed
1135 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1136     out all the space. operator--() did not apply size_mask after
1137     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1138     order to avoid problems with the _NonVolatileReader functions.
1139     - bugfix: Stream.h: added a missing divide by BytesPerSample in
1140     GetWriteSpace(). Since this function is currently only used in
1141     the stream's qsort() compare function, it didn't trigger any
1142     bugs.
1143     - Resampler.h, Synthesizer.h: cubic interpolation now works in
1144     24bit mode too. Faster method to read 24bit words on little
1145     endian machines (x86): replaced 3 byte reads + shifts with a 1
1146     unaligned 32bit read and shift
1147     - experimental support for MS Windows (MIDI input via MME, AUDIO
1148     output via ASIO)
1149     - made handling of SIGINT signal (Ctrl-C) a bit more robust
1150 iliev 1541 - support for monitoring the total number of active disk streams
1151     (new LSCP commands: GET TOTAL_STREAM_COUNT,
1152     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1153 persson 1455
1154 senoner 1500 * AUDIO driver:
1155 persson 1534 - added Windows ASIO low latency audio driver
1156 senoner 1500
1157 senoner 1485 * MIDI driver:
1158 schoenebeck 1495 - added MME Windows MIDI driver
1159 senoner 1485
1160 schoenebeck 1471 * LSCP server:
1161     - added support for Windows style path / filenames, however with
1162     forward slash path separators instead of backslash
1163     (i.e. "C:/foo/bar.gig")
1164 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
1165     apostrophes as well
1166 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1167     "LIST FILE INSTRUMENTS <file>" and
1168     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1169     about an arbitrary instrument file on the system where the sampler is
1170     running on
1171 schoenebeck 1471
1172 schoenebeck 1424 Version 0.5.0 (15 October 2007)
1173 schoenebeck 947
1174 schoenebeck 1065 * packaging changes:
1175 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
1176     API header files anymore
1177 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
1178     the Doxygen API documentation (explicitly listed in Doxyfile.in)
1179 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
1180     capable to execute our autoconf environment, thus no need anymore
1181     to maintain the compile time configuration file (osx/version.h) for
1182     OSX manually (patch by Toshi Nagata)
1183 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
1184     parameters
1185 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
1186     C++ API header files, all implementation internal global definitions
1187     are now in global_private.h
1188     - atomic.h is not exposed to the C++ API anymore
1189     - no need to include config.h anymore for using LS's API header files
1190     - fixed warnings in API doc generation
1191 schoenebeck 1065
1192 schoenebeck 947 * general changes:
1193     - replaced the old, confusing MIDI program change mechanism by a
1194     flexible MIDI instrument mapper which allows to map arbitrary
1195 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
1196 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
1197     loaded on the respective channel when such MIDI program change
1198     messages arrive, beside that, each entry allows to define a life-time
1199     strategy for the instrument, so the user can define whether the
1200     instrument should i.e. be permanently loaded (to be able to switch
1201     quickly among sounds) or i.e. loaded just on demand when the
1202     respective program change arrives (to safe RAM space), as well as a
1203     global volume factor for each entry, so the user can adjust the volume
1204     dynamic of his mapped instrument collection without having to modify
1205 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
1206     MIDI instrument maps and assign each sampler channel individually
1207     a certain map, so that i.e. separation of normal instruments and
1208     drumkits is possible
1209 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
1210     MIDI instrument maps, MIDI instruments, FX sends, global volume.
1211 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
1212     due to a constant size RingBuffer FIFO which is now replaced by a
1213     dynamic (unlimited) size std::list FIFO
1214 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
1215     output channels for being processed by external effect processors
1216     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1217     controllers
1218 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
1219 iliev 1130 - Implemented new, improved notification system
1220 schoenebeck 1149 - fixed compilation errors regarding OSX
1221     (patch by Toshi Nagata)
1222 iliev 1161 - implemented instruments database
1223 iliev 1345 - added support for escape sequences to the instruments database
1224 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
1225     within the sampler's process (by using instrument editor plugins),
1226     you'll notice the new "Registered instrument editors:" message on
1227 schoenebeck 1407 startup, added a new LSCP command:
1228     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1229 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
1230     given sampler channel, the plugin path can be overridden at compile
1231     time with ./configure --enable-plugin-dir=/some/dir
1232 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
1233     in the sampler's process to safely edit instruments while playing
1234     without a crash (hopefully) by either suspending single regions
1235     wherever possible or if unavoidable whole engine(s)
1236 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
1237     policy and priority on thread level, set a minimum stack size for
1238     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1239     threads simply inherited properties of starting thread instead of
1240     setting their own policy and priority
1241 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
1242     main process did not wait for the stack trace process to finish
1243     its output
1244 persson 1248 - fixed some minor memory leaks
1245 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1246     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1247 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1248     register, to avoid relocations in the text segment at runtime)
1249 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1250 schoenebeck 947
1251     * MIDI driver:
1252     - dispatch bank select (MSB and LSB) messages
1253    
1254 schoenebeck 1049 * audio driver:
1255     - the ALSA audio output driver parameters now reflect the correct
1256     parameter value ranges for the respective selected sound card
1257     (patch by Till Wimmer, a bit fixed and extended)
1258    
1259 persson 951 * Gigasampler format engine:
1260     - if a filter is used and EG2 finishes before EG1, let the voice
1261     die when EG2 has finished (this fixes a problem with clicks and
1262     voice starvation for some gigs)
1263 persson 1038 - playback is no longer disabled during instrument loading
1264     - all notes playing on a channel that changes its instrument keep
1265     playing with the old instrument until they get a note off
1266     command
1267 persson 1039 - EG fix: a release value of zero could cause noises or crash
1268 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1269 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1270     above max sustain level, which means that there is a decay phase
1271     even if sustain is 100%
1272 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1273     noises or crashes
1274 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1275 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1276     supplied to the configure script (fixes #46)
1277 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1278     instead of a fix value
1279 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1280     127 (solo mode) only kill voices if the respective mode really
1281     changed
1282 persson 951
1283 schoenebeck 1244 * LSCP server:
1284     - fixed compile time error for old Bison versions
1285     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1286 schoenebeck 1245 - parser now supports extended ASCII character set
1287     (up to ASCII code 255, i.e. includes now umlauts and accents)
1288     - filename arguments in LSCP commands now allow to use escape
1289     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1290     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1291     code value like \xf2) (fixes bug #24)
1292 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1293     least one of their text-based parameters (i.e. name, description):
1294     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1295     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1296     "SET DB_INSTRUMENT_DIRECTORY NAME",
1297     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1298     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1299     "FIND DB_INSTRUMENT_DIRECTORIES"
1300 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1301     occured, the unexpected character and the actually expected, possible
1302     character(s), the latter only if less than 5 possibilities)
1303 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1304     settings
1305 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1306     of strings were treated as being one string containing commas
1307     (fixes #57)
1308 schoenebeck 1244
1309 iliev 959 * Bug fixes:
1310     - fixed crash occurring on certain LSCP scripts (Bug 39)
1311 persson 1038 - another thread safety fix for lscp "load engine" and "set
1312     channel audio output device"
1313 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1314     on a sampler channel with connected MIDI device
1315 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1316     device connected to a sampler channel to number less then or equal
1317     to the index of the port to which the sampler channel is connected.
1318 iliev 1296 - The previous bindings were not been disconnected when altering
1319     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1320     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1321 iliev 1297 - The active stream/voice count statistic was incorrect.
1322 iliev 1298 - notification events were not been sent for some sampler
1323     channel changes
1324 iliev 1305 - added default min and max values to restrict the number of allowed
1325     audio output channels and MIDI input ports
1326 iliev 1306 - the connection to the PCM interface is now closed when destroying
1327     an audio output device
1328 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1329 iliev 959
1330 schoenebeck 1221 * test cases:
1331     - updated and fixed (haven't been touched in a while)
1332    
1333 schoenebeck 937 Version 0.4.0 (24 November 2006)
1334 persson 696
1335 schoenebeck 697 * packaging changes:
1336 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1337     to post-(un)install steps; added devel package for liblinuxsampler;
1338     to linuxsampler.spec (RPM)
1339 schoenebeck 697 - install necessary development header files for allowing 3rd party
1340     applications to link against liblinuxsampler
1341     - liblinuxsampler's API documentation can be generated with 'make docs'
1342     (Doxygen required)
1343 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1344     implementation (currently either an integer math solution or a
1345     di-harmonic approximation), automatic detection can be overriden
1346     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1347     configure script argument though (mandatory for cross-compilation)
1348 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1349     provided some on his own (as CXXFLAGS)
1350 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1351     messages
1352 schoenebeck 852 - added compile time options to allow disabling the various audio and
1353     MIDI drivers
1354 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1355     (patch by Ebrahim Mayat)
1356 schoenebeck 697
1357 persson 696 * Gigasampler format engine:
1358 schoenebeck 738 - extensive synthesis optimization
1359     (reimplementation of EGs and LFO(s), removed synthesis parameter
1360     prerendering and the synthesis parameter matrix in general, splitting
1361     each audio fragment into subfragments now where each subfragment uses
1362 persson 830 constant pitch and filter coefficients. The volume coefficient is
1363     linearly interpolated inside a subfragment, unless
1364     --disable-interpolate-volume is set.)
1365 persson 696 - fine tuning of the EG modulation parameters
1366 persson 729 - improved filter cutoff calculation by adding support for the
1367     following gig parameters: Cutoff freq (used when no cutoff
1368     controller is defined), Control invert, Minimum cutoff, Velocity
1369 persson 791 curve and Velocity range. The keyboard tracking now scales
1370     cutoff frequency instead of resonance.
1371 persson 877 - added support for gig parameter Resonance.
1372 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1373 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1374     which can be overridden with --enable-global-attenuation
1375 persson 783 - EG fixes: made the length of "attack hold" stage more
1376     accurate. Release stage can now start before attack stage
1377 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1378     time now has a minimal value to prevent clicks.
1379 persson 799 - fixed pitch changes larger than one octave
1380 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1381     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1382     all modes can be altered via standard GM messages, that is CC5 for
1383     altering portamento time, CC65 for enabling / disabling portamento
1384     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1385 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1386     parameter) and crossfade
1387 persson 831 - added support for the "attenuation controller threshold" gig
1388     parameter
1389 persson 832 - added smoothing of volume changes caused by control change
1390     messages
1391 persson 865 - sample loop parameters are now taken from the DimensionRegion
1392     instead of the wave chunk
1393     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1394     not equal to a power of two
1395 persson 877 - reimplementation of the filter algorithm. The new filter is more
1396     accurate and supports all gig filter types, including bandreject
1397     and lowpass turbo.
1398 persson 903 - real support for 24 bit samples - samples are not truncated to
1399     16 bits anymore
1400     - support for aftertouch (channel pressure, not polyphonic
1401     aftertouch)
1402 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1403     amplifying from 0)
1404 persson 696
1405 schoenebeck 711 * LSCP server:
1406     - fixed application exit on broken pipe error (fixes bug #20)
1407 iliev 793 - fixed the notification messages delay due to lack of
1408     network activity (fixes bug #26)
1409 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1410     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1411 schoenebeck 711
1412 schoenebeck 838 * audio driver:
1413     - added aRts audio output driver (by no means RT safe)
1414    
1415 schoenebeck 775 * MIDI driver:
1416     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1417     messages several times instead of once
1418 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1419     for events (i.e. for offline rendering based MIDI drivers)
1420 persson 922 - added checks for bad MIDI data
1421 schoenebeck 775
1422 schoenebeck 900 * linuxsampler application:
1423     - show available sampler engine types on startup
1424    
1425 schoenebeck 705 * general changes:
1426     - support for muting sampler channels and solo mode of the same, two new
1427     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1428     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1429     introduced for this, the behavior is the same like on a mixer console
1430 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1431     --enable-process-muted-channels which can be used to enable the
1432     processing of muted channels.
1433 iliev 777 - support for sostenuto pedal
1434 iliev 779 - support for monitoring the total number of active voices
1435 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1436     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1437 persson 835 - fixed some memory management errors
1438 persson 841 - fixed some concurrency problems that could lead to crashes when
1439     LSCP commands were executed
1440 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1441     sampler channel (fixes bug #36)
1442 schoenebeck 705
1443 schoenebeck 692 Version 0.3.3 (15 July 2005)
1444 schoenebeck 686
1445     * packaging changes:
1446     - fixed compilation with gcc 4.0
1447    
1448 schoenebeck 687 * Gigasampler format engine:
1449     - LFO preprocessing was performed even though the respective LFO was
1450     disabled by the instrument patch (minor efficiency fix)
1451 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1452     for volume ramp downs in the same fragment (needed for current voice
1453     stealing implementation) then simply inform the user with a warning
1454     about possible click sounds and reduce the volume ramp down
1455     appropriately instead of cancelling the audio device connection
1456 schoenebeck 687
1457 schoenebeck 677 Version 0.3.2 (24 June 2005)
1458 schoenebeck 609
1459     * packaging changes:
1460     - updated autotools build files to compile on OS X
1461     (conditional compilation of CoreMIDI and MidiShare drivers)
1462 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1463     './configure --disable-asm' (definitely not recommended)
1464 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1465     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1466     (due to 'dist-bzip2' automake option)
1467 schoenebeck 649
1468     * Gigasampler format engine:
1469     - support for the gig parameters for "release velocity response" curves
1470     - fine tuning of the EGADSR envelope
1471     - volume of release triggered samples now depends on note-on velocity,
1472     note length and gig parameter "release trigger decay" instead of
1473     note-off velocity.
1474 schoenebeck 663 - revised voice stealing
1475     (fixes crash and endless loop caused by voice stealing)
1476 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1477 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1478     instead of when the respective voice is actually launched
1479     (fixes undefined behavior if stolen voices belonged to a key group -
1480     this case was followed by a "killed voice survived" error message)
1481 schoenebeck 669 - fixed minor issue with null/silence samples
1482     (those stole voices even though they don't need a voice at all which
1483     resulted in "voice stealing didn't work out" messages)
1484 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1485     instrument or audio output device change
1486 schoenebeck 654
1487 schoenebeck 620 * LSCP server:
1488 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1489 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1490 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1491 schoenebeck 609
1492 schoenebeck 668 * linuxsampler application:
1493     - added command line parameters --lscp-addr and --lscp-port to override
1494     default IP address and port of LSCP server
1495    
1496 schoenebeck 579 Version 0.3.1 (24 May 2005)
1497    
1498     * initial release
