NKSP: Added standard units support for numbers and final "!" operator:

* NKSP strictness: Variable names, function names and preprocessor condition
  names must start with a regular character (a-z or A-Z); starting them with
  a digit or underscore is no longer allowed.

* NKSP parser fix: equal comparison operator "=" and not equal comparison
  operator "#" must only accept integer operands.

* NKSP language: Implemented support for standard units like Hertz, seconds,
  Bel including support for metric unit prefixes; so one can now e.g.
  conveniently use numbers in scripts like "5us" meaning "5 microseconds",
  or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
  "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).

* NKSP language: Introduced "final" operator "!" which is specifically
  intended for synthesis parameter values to denote that the synthesis
  parameter value is intended to be the "final" value for that synthesis
  parameter that should explicitly be used by the engine and thus causing
  the sampler engine to ignore all other modulation sources for the same
  synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
  variable or formula with this new "!" operator the expression is marked as
  being "final".

* Bumped version (2.1.1.svn4).

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

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

220     - Implemented built-in script function "change_decay()".
221     - Implemented built-in script function "change_release()".
222 schoenebeck 2962 - Fixed all change_*() built-in script functions to apply their
223     synthesis parameter changes immediately in case the respective note
224     was triggered at the same time, instead of scheduling the parameter
225     change, especially because it would cause some parameter types's
226     changes either to be ramped (i.e. change_vol()) or other types even
227     to have not effect at all (i.e. change_attack()).
228 schoenebeck 2965 - Implemented built-in script function "sh_left()".
229     - Implemented built-in script function "sh_right()".
230 schoenebeck 2970 - Implemented built-in script function "min()".
231     - Implemented built-in script function "max()".
232 schoenebeck 2972 - NKSP Fix: "init" event handler was not always executed when a script
233     was loaded.
234     - NKSP built-in wait() script function: abort script execution if
235     a negative or zero wait time was passed as argument (since this is
236     a common indication of a bug either of the script or even of the
237     engine, which could lead to RT instability or even worse).
238 schoenebeck 2974 - ScriptVM: Implemented automatic suspension of RT safety
239     threatening scripts.
240 schoenebeck 3008 - Provide more user friendly error messages on syntax errors.
241 schoenebeck 3013 - Fixed NKSP parser warning "Not a statement" when assigning an
242     initializer list to an array variable.
243 schoenebeck 3073 - Implemented built-in script array variable "%ALL_EVENTS".
244 schoenebeck 3076 - Implemented built-in script function "in_range()".
245 schoenebeck 3118 - Implemented built-in script function "change_amp_lfo_depth()".
246     - Implemented built-in script function "change_amp_lfo_freq()".
247     - Implemented built-in script function "change_pitch_lfo_depth()".
248     - Implemented built-in script function "change_pitch_lfo_freq()".
249 schoenebeck 3188 - Implemented built-in script function "change_vol_time()".
250     - Implemented built-in script function "change_tune_time()".
251     - Implemented built-in script function "fade_in()".
252     - Implemented built-in script function "fade_out()".
253     - Fixed acceptance of wrong data type of parameters passed to built-in
254     script functions "change_vol()", "change_tune()", "change_pan()",
255     "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
256     "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
257     "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
258 schoenebeck 3193 - Added built-in script function "get_event_par()" and implemented some
259     of its possible parameter selections.
260     - Added built-in script function "set_event_par()" and implemented some
261     of its possible parameter selections.
262 schoenebeck 3205 - Fixed a bunch of scheduler time related bugs.
263 schoenebeck 3207 - Fixed polyphonic variables not being reset to zero after usage.
264 schoenebeck 3212 - Built-in "ignore_event()" function: argument is now optional, like with
265     built-in function "ignore_controller()".
266 schoenebeck 3214 - Implemented built-in script function "change_velo()".
267     - Implemented built-in script function "change_note()".
268 schoenebeck 3218 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
269     intuitive behavior if used in combination with "change_vol_time()" or
270     "change_tune_time()" respectively: now tuning/volume changes are only
271     assigned (without delay) immediately to a new note if the respective
272     timing function has not been called before, otherwise the volume/tuning
273     changes are automatically faded (before, only the event's time stamp was
274     relevant).
275 schoenebeck 3221 - Implemented built-in script function "array_equal()".
276     - Implemented built-in script function "search()".
277     - Implemented built-in script function "sort()".
278     - NKSP Fix: Never suspend "init" event handlers.
279 schoenebeck 3228 - Implemented built-in script function "same_region()" (currently only
280     available for gig format engine).
281 schoenebeck 3246 - Added built-in script constant "$NKSP_LINEAR".
282     - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
283     - Implemented built-in script function "change_vol_curve()".
284     - Implemented built-in script function "change_tune_curve()".
285 schoenebeck 3251 - built-in "play_note()" function now supports a sample playback start
286     offset with argument 3, where special value -1 means to use the regular
287     sample offset as defined by the instrument file.
288 schoenebeck 3253 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
289     - Built-in variable $EVENT_NOTE is now a read-only variable.
290     - Built-in variable $EVENT_VELOCITY is now a read-only variable.
291     - built-in "play_note()" function now accepts -2 for its fourth argument
292     (note duration) which means the life time of the note shall be sticked
293     to the requested note number of argument 1.
294     - Fix: built-in "play_note()" function now returns 0 as result value if
295     -1 was passed for its fourth argument (note duration) and the respective
296     parent note is already gone.
297 schoenebeck 3255 - Implemented built-in script function "change_play_pos()".
298 schoenebeck 3257 - NKSP language: Added support for user declared const array variables.

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

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

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

857     after MIDI/audio device creation failure
858 schoenebeck 2275 - When creating MIDI instrument map entries with "PERSISTENT" type, the

884 schoenebeck 2509 - ignore missing LADSPA paths without ignoring valid LADSPA paths
885     (fixes #208)
886 schoenebeck 2523 - Fixed bug in LSCP grammar definition which caused a statement like
887     "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
888     practically irrelevant, however it caused problems with the new LSCP
889     shell's auto completion feature).
890 schoenebeck 2672 - Fixed MIDI program change messages being ignored if quickly executed
891     after each other (fixes #231).

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

970 persson 1888 - applied old fixes to the ASIO driver that were included in the
971     previous binary release but accidentally never committed to CVS
972     (fixes #117)
973 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
974     win64)

1010     instrument database compilable
1011 schoenebeck 1930 - added instrument database support on Windows
1012     works with both standalone mode and VST plugin.
1013     the instruments DB file is located in
1014     %USERPROFILE%\.linuxsampler\instruments.db which allows different
1015     databases for each windows user
1016     if no DB is present it automatically creates the .linuxsampler subdir
1017     and then creates an empty DB
1018 persson 1943 - fixed recursive import, which was broken on Windows
1019 iliev 1603
1020 persson 1644 * Gigasampler format engine:

1024     isn't running
1025 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
1026     enough for piano gigs with pedal noise samples
1027 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
1028     respective FX send MIDI controller was used
1029 schoenebeck 1724 - added support for GM global device volume SysEx message
1030 schoenebeck 1762 (can be selected at compile time to either apply globally to the
1031     whole sampler [default] or only to the sampler channels that are
1032     connected to the respective MIDI input port the SysEx message arrived
1033     on)
1034 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
1035     sometimes wrongly killed in the same buffer, causing no sound to
1036     be played
1037 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
1038     which is usally used to switch a part between chromatic sounds and
1039     drumkit sounds (as opposed to their common default setting of MIDI
1040     part 10 being a drumkit part and all other ones chromatic parts), in
1041     LS however one can switch between the first 16 MIDI instrument maps
1042     defined for the sampler
1043 persson 1764 - made it possible to create multiple sample channels even if the
1044     audio thread isn't running

1047     un-cache the respective sample if it's really not used by any
1048     sampler engine anymore
1049     - re-cache samples in case they were changed by an instrument editor,
1050     e.g. when a sample was added while playing (#82)
1051 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
1052     same time stamp as the voice's note-on event and occured both in the
1053     same audio fragment cycle (fixes bug #112)
1054 persson 1858 - added support for the "fine tune" and "pitch bend range"
1055     instrument-level gig parameters
1056     - fixed minor artifacts in pitch bend handling
1057 schoenebeck 1860 - added support for GS Reset SysEx message
1058 persson 1862 - allow gig files to use unlimited downward pitch shifting
1059     - added a limit check for upward pitch shifting
1060 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
1061     note was silent
1062 persson 1923 - fixed crash happening when a pitch bend event arrived at the
1063     same time a new instrument was loading
1064 persson 1644
1065 schoenebeck 1687 * LSCP server:
1066     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1067     react on MIDI data arriving on certain sampler channels (so far only
1068     Note-On and Note-Off events are sent via this LSCP event)
1069 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1070     react on MIDI data arriving on certain MIDI input devices (so far only
1071     Note-On and Note-Off events are sent via this LSCP event)
1072 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1073     SET DB_INSTRUMENT FILE_PATH
1074 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1075     frontends to send MIDI messages to specific sampler channel
1076     - added two additional fields to GET FILE INSTRUMENT INFO command -
1077     KEY_BINDINGS and KEYSWITCH_BINDINGS
1078 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1079     was incorrect
1080 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
1081 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
1082     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1083     be triggered respectively
1084     - added new LSCP command "SET STREAMS" to globally alter the maximum
1085     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1086     which will be triggered respectively
1087 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1088     a gigedit file dialog is opened)
1089 iliev 1848 - close all connections when LSCPServer is deleted
1090 iliev 1882 - hard close of all sockets on exit
1091 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1092     driver
1093 schoenebeck 1687
1094 iliev 1761 * Bug fixes:
1095     - fixed a crash which occurs when removing a sampler channel waiting
1096     to start instrument loading after another channel
1097 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
1098     instrument loading in progress (bug #113)
1099 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
1100     instrument with PERSISTENT load mode
1101 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
1102     - fixed memory leaks when issuing the following LSCP commands:
1103     GET AUDIO_OUTPUT_DRIVER INFO
1104     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1105     GET MIDI_INPUT_DRIVER INFO
1106     GET MIDI_INPUT_DRIVER_PARAMETER INFO

1108 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1109 iliev 1847 - fixed crash when changing the audio output device of a sampler
1110     channel with loaded instrument and start playing notes
1111 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
1112 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
1113     PowerPC, which probably could cause crashes on that platform
1114 persson 1889 - fixed a memory management error which could cause a crash when a
1115     plugin was unloaded
1116 persson 1896 - bugfix: two private structs had the same name, which could cause
1117     problems if the linker chose the wrong constructor
1118 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
1119     Windows

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