* sfz/sf2 engines: RT-safeness: avoid malloc in audio thread
* sfz/sf2 engines: fixed a bug that could cause voice stealing to fail

1 Version CVS HEAD (?)
2
3 * packaging changes:
4 - fixed building with newer MinGW-w64
5
6 * general changes:
7 - Refactoring: moved the independent code from
8 the Gigasampler format engine to base classes
9 - command line option '--profile' is currently disabled, since the
10 respective profiling code is currently broken
11 - Introduced support for optional environment variable
12 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
13 where the sampler shall look for instrument editor plugins
14 (patch by Luis Garrido, slightly modified).
15
16 * Gigasampler format engine:
17 - implemented the "round robin keyboard" dimension
18 - fixed round robin and random dimensions for cases when number of
19 dimension zones is not a power of two
20 - made round robin use a counter for each region instead of each
21 key
22
23 * SFZ format engine:
24 - Initial implementation (not usable yet)
25 - added support for v2 multiple stage envelope generators
26 - added a fine-tuned v1 envelope generator instead of using the
27 one from the gig engine
28 - fixed memory leak and memory handling errors
29 - added support for trigger=first, trigger=legato and sw_previous
30 - allow non-numerical key values ("C#4" for example)
31 - "key" opcode now sets pitch_keycenter too
32 - fixed error when unloading instrument with same sample used by
33 multiple regions
34 - added some opcode aliases, like loopmode for loop_mode, to be
35 more compatible
36 - added support for trigger=release and rt_decay
37 - added support for off_mode=normal
38 - added support for random, seq_position, seq_length and volume
39 - added v1 LFO opcodes to parser (no support in engine yet)
40 - added support for amp_veltrack and amp_velcurve_N
41 - fine-tuned the default velocity curve
42 - added support for transpose
43 - fixed crash when using sw_down/up
44 - improved logic for sw_lokey/hikey/up/down/last
45 - added more v1 aliases to parser
46 - reduced memory usage for sfz data
47 - RT-safeness: avoid malloc in audio thread
48 - fixed a bug that could cause voice stealing to fail
49
50 * SoundFont format engine:
51 - Initial implementation (not usable yet)
52 - RT-safeness: avoid malloc in audio thread
53 - fixed a bug that could cause voice stealing to fail
54
55 * Host plugins:
56 - AU bugfix: failed to destroy its audio/MIDI devices
57 - Listen to all interfaces on Mac OS X (INADDR_ANY)
58 - VST bugfix: If the host called resume() before and after
59 changing sample rate or block size, the number of channels was
60 incorrectly set to two. This caused silence in Cubase 5.
61
62 * MIDI driver:
63 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
64 the ALSA sequencer client name
65
66 * LSCP server:

72
73 Version 1.0.0 (31 July 2009)
74
75 * packaging changes:
76 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
77 causing e.g. the libgig test to fail when
78 "./configure --disable-jack-driver" was used
79 (patch by Alexis Ballier)
80 - fixed compilation with gcc 4.3
81 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
82 - fixed configure so it detects x86_64 (#107)
83 - fixes for building with newer MinGW versions
84 - fix for building with bison 2.4 (#111)
85 - fixed building with libgig installed in a non-standard directory
86 - minor fix in configure for mmsystem.h detection on MinGW
87 - Windows: look for editor plugins and Fantasia using base
88 directory of liblinuxsampler dll (look in the same directory and one
89 directory above)
90 - configure script fix: removed unconditional use of SSE
91 - fixed building with sqlite installed in a non-standard directory
92 - when cross-compiling, don't try to create instruments.db
93 - fix for new mingw-w64 version, which has usleep
94
95 * general changes:
96 - bugfix: on some POSIX systems instrument editor plugins refused to
97 load as we used a non-portable Linux specific struct field
98 (fixes bug #70, patch by Ronald Baljeu)
99 - fixed endless loop which occured when loading an instrument editor
100 plugin DLL on Windows systems failed
101 - fixed memory leaks that occurred when liblinuxsampler was unloaded
102 - optimized the SynchronizedConfig class so it doesn't wait
103 unnecessarily long after an update
104 - added support for notifying instrument editors on note-on / note-off
105 events (e.g. to highlight the pressed keys on the virtual keyboard
106 of gigedit)
107 - added support for triggering notes by instrument editors (see above)
108 - be verbose on DLL load errors (on Linux)
109 - fixed di-harmonic triangle LFO implementation (this LFO implementation
110 is only used by very few systems, most pick the int math
111 implementation, which is usually faster)
112 - fixes for audio drivers with varying buffer sizes
113 - experimental support for running LinuxSampler as a DSSI, LV2 and
114 VST plugin
115 - notification events for stream/voice count statistics are now sent
116 only when there are actual changes
117 - added memory ordering constraints to improve stability on
118 multi-core and multi-cpu systems
119 - maximum voices and disk streams can now be altered at runtime
120 - fixed CPU feature detection on x86_64 (maybe fixes #108)
121 - automatic stacktrace mechanism is now turned off by default and can
122 be switched on by command line option "--stacktrace" (the automatic
123 stacktrace mechanism seems to be broken on most systems at the moment)
124 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
125 a pointer to the launched InstrumentEditor object
126 - added optional 3rd party user data parameter for following
127 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
128 InstrumentEditor::Launch(),
129 InstrumentManager::LaunchInstrumentEditor()
130 - theoretical fix: made SynchronizedConfig follow C++0x memory
131 model more strictly
132 - fixes for using large audio device buffers
133 - Windows: add the installation directory to the DLL search path
134 when loading an editor plugin (solves problems with VST and
135 gigedit on systems with other GTK versions installed)
136
137 * audio driver:
138 - removed the nonsense audio channel constraint (which was hard coded to
139 max. 100 audio channels) for most audio drivers
140 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
141 opposed to the LSCP specs
142 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
143 reflected the wrong value
144 - fixed a memory management bug in ASIO driver
145 - Makefile fix: JACK_CFLAGS wasn't used
146 - JACK: use jack_client_open instead of the deprecated
147 jack_client_new
148 - added (experimental) CoreAudio driver
149 - applied old fixes to the ASIO driver that were included in the
150 previous binary release but accidentally never committed to CVS
151 (fixes #117)
152 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
153 win64)
154 - VST: added support for sample rate and buffer size changes
155 - VST: close editor (Fantasia) when the VST is removed
156 - VST: avoid opening Fantasia more than once for each VST instance
157 - VST: export main function as "main" on Linux too (fix for
158 energyXT)
159 - VST: changed number of output channels from one stereo to 16
160 stereo
161 - added channel routing, fxsends and midi maps to the settings
162 stored in the plugin state
163 - performance optimization of AudioChannel::MixTo() and
164 AudioChannel::CopyTo() methods using GCC vector exensions
165 (if available)
166 - ASIO fixes: avoid initializing the device twice, avoid throwing
167 exception when getting parameters from a disconnected device
168
169 * MIDI driver:
170 - added JACK MIDI driver
171 - dispatch bank select as ordinary CC as well, the user might seriously
172 want to (mis)use it for some purpose ("fixed" in all current MIDI
173 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
174 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
175 CoreMidi or AU
176 - fixed mingw-w64 compilation error in MME driver
177 - made program change handling in MIDI thread real-time safe by
178 moving the logic to a non-RT thread
179 - fixed minor memory leak in ALSA driver
180
181 * instruments database:
182 - avoid time consuming samples scanning when adding instruments
183 to the instruments database
184 - added support for handling lost files in the instruments database
185 - Implemented option for adding instruments in separate directories
186 in the instruments database
187 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
188 - work-around for missing fnmatch function on Windows to make
189 instrument database compilable
190 - added instrument database support on Windows
191 works with both standalone mode and VST plugin.
192 the instruments DB file is located in
193 %USERPROFILE%\.linuxsampler\instruments.db which allows different
194 databases for each windows user
195 if no DB is present it automatically creates the .linuxsampler subdir
196 and then creates an empty DB
197 - fixed recursive import, which was broken on Windows
198
199 * Gigasampler format engine:
200 - fixed a memory leak that could happen when a channel was deleted
201 while notes were playing
202 - made it possible to load an instrument even if the audio thread
203 isn't running
204 - added partial support for the "Controller Triggered" MIDI rule,
205 enough for piano gigs with pedal noise samples
206 - minor fix: only mark FX sends as being modified if really the
207 respective FX send MIDI controller was used
208 - added support for GM global device volume SysEx message
209 (can be selected at compile time to either apply globally to the
210 whole sampler [default] or only to the sampler channels that are
211 connected to the respective MIDI input port the SysEx message arrived
212 on)
213 - bugfix: notes triggered at position 0 in the audio buffer were
214 sometimes wrongly killed in the same buffer, causing no sound to
215 be played
216 - added support for chromatic / drumkit mode Roland GS Sysex message
217 which is usally used to switch a part between chromatic sounds and
218 drumkit sounds (as opposed to their common default setting of MIDI
219 part 10 being a drumkit part and all other ones chromatic parts), in
220 LS however one can switch between the first 16 MIDI instrument maps
221 defined for the sampler
222 - made it possible to create multiple sample channels even if the
223 audio thread isn't running
224 - fixed crash when removing channel with active voices (#116)
225 - bugfix: on sample reference changes (instrument editor), only
226 un-cache the respective sample if it's really not used by any
227 sampler engine anymore
228 - re-cache samples in case they were changed by an instrument editor,
229 e.g. when a sample was added while playing (#82)
230 - fixed hanging notes which occured when note-off event had the exact
231 same time stamp as the voice's note-on event and occured both in the
232 same audio fragment cycle (fixes bug #112)
233 - added support for the "fine tune" and "pitch bend range"
234 instrument-level gig parameters
235 - fixed minor artifacts in pitch bend handling
236 - added support for GS Reset SysEx message
237 - allow gig files to use unlimited downward pitch shifting
238 - added a limit check for upward pitch shifting
239 - bugfix: sometimes, when playing a note twice fast, the second
240 note was silent
241 - fixed crash happening when a pitch bend event arrived at the
242 same time a new instrument was loading
243
244 * LSCP server:
245 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
246 react on MIDI data arriving on certain sampler channels (so far only
247 Note-On and Note-Off events are sent via this LSCP event)
248 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
249 react on MIDI data arriving on certain MIDI input devices (so far only
250 Note-On and Note-Off events are sent via this LSCP event)
251 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
252 SET DB_INSTRUMENT FILE_PATH
253 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
254 frontends to send MIDI messages to specific sampler channel
255 - added two additional fields to GET FILE INSTRUMENT INFO command -
256 KEY_BINDINGS and KEYSWITCH_BINDINGS
257 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
258 was incorrect
259 - Optimized the retrieval of the MIDI instrument mappings
260 - added new LSCP command "SET VOICES" to globally alter the maximum
261 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
262 be triggered respectively
263 - added new LSCP command "SET STREAMS" to globally alter the maximum
264 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
265 which will be triggered respectively
266 - bugfix: retry if "select" returns EINTR (this fixes a crash when
267 a gigedit file dialog is opened)
268 - close all connections when LSCPServer is deleted
269 - hard close of all sockets on exit
270 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
271 driver
272
273 * Bug fixes:
274 - fixed a crash which occurs when removing a sampler channel waiting
275 to start instrument loading after another channel
276 - fixed a crash which occurs when removing a sampler channel with
277 instrument loading in progress (bug #113)
278 - fixed termination caused by uncaught exception when adding MIDI
279 instrument with PERSISTENT load mode
280 - fixed possible iterator invalidations when resetting the sampler
281 - fixed memory leaks when issuing the following LSCP commands:
282 GET AUDIO_OUTPUT_DRIVER INFO
283 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
284 GET MIDI_INPUT_DRIVER INFO
285 GET MIDI_INPUT_DRIVER_PARAMETER INFO
286 - fixed possible compilation error when sqlite is not present
287 - fixed orphaned pointers when setting maximum voices limit (bug #118)
288 - fixed crash when changing the audio output device of a sampler
289 channel with loaded instrument and start playing notes
290 - fixed endless loop in Engine::SuspendAll() (bug #120)
291 - fixed a low-level atomic load function that was broken on 64-bit
292 PowerPC, which probably could cause crashes on that platform
293 - fixed a memory management error which could cause a crash when a
294 plugin was unloaded
295 - bugfix: two private structs had the same name, which could cause
296 problems if the linker chose the wrong constructor
297 - fixed low-level ConditionServer usage bug that caused lockups on
298 Windows
299
300
301 Version 0.5.1 (6 December 2007)
302
303 * packaging changes:
304 - added autoconf checks for pthread library
305 - added autoconf check for pthread bug found on certain NPTL-enabled
306 glibc versions (see Gentoo bug report #194076)
307 - added autoconf checks for MS Windows
308
309 * general changes:
310 - bugfix: the thread used by an editor plugin didn't die when the
311 editor closed
312 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
313 out all the space. operator--() did not apply size_mask after
314 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
315 order to avoid problems with the _NonVolatileReader functions.
316 - bugfix: Stream.h: added a missing divide by BytesPerSample in
317 GetWriteSpace(). Since this function is currently only used in
318 the stream's qsort() compare function, it didn't trigger any
319 bugs.
320 - Resampler.h, Synthesizer.h: cubic interpolation now works in
321 24bit mode too. Faster method to read 24bit words on little
322 endian machines (x86): replaced 3 byte reads + shifts with a 1
323 unaligned 32bit read and shift
324 - experimental support for MS Windows (MIDI input via MME, AUDIO
325 output via ASIO)
326 - made handling of SIGINT signal (Ctrl-C) a bit more robust
327 - support for monitoring the total number of active disk streams
328 (new LSCP commands: GET TOTAL_STREAM_COUNT,
329 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
330
331 * AUDIO driver:
332 - added Windows ASIO low latency audio driver
333
334 * MIDI driver:
335 - added MME Windows MIDI driver
336
337 * LSCP server:
338 - added support for Windows style path / filenames, however with
339 forward slash path separators instead of backslash
340 (i.e. "C:/foo/bar.gig")
341 - allow naughty liblscp to send non-string device parameters within
342 apostrophes as well
343 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
344 "LIST FILE INSTRUMENTS <file>" and
345 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
346 about an arbitrary instrument file on the system where the sampler is
347 running on
348
349 Version 0.5.0 (15 October 2007)
350
351 * packaging changes:
352 - config.h is not going to be installed along with liblinuxsampler's
353 API header files anymore
354 - only the API relevant header (and source) files will be exported to
355 the Doxygen API documentation (explicitly listed in Doxyfile.in)
356 - added completely new XCode project files for Mac OSX which is now
357 capable to execute our autoconf environment, thus no need anymore
358 to maintain the compile time configuration file (osx/version.h) for
359 OSX manually (patch by Toshi Nagata)
360 - fixed buggy boolean --enable-foo / --disable-foo configure script
361 parameters
362 - global.h now only covers global definitions that are needed for the
363 C++ API header files, all implementation internal global definitions
364 are now in global_private.h
365 - atomic.h is not exposed to the C++ API anymore
366 - no need to include config.h anymore for using LS's API header files
367 - fixed warnings in API doc generation
368
369 * general changes:
370 - replaced the old, confusing MIDI program change mechanism by a
371 flexible MIDI instrument mapper which allows to map arbitrary
372 (MIDI bank, MIDI program) pairs with arbitrary
373 (engine type, instrument file, file index) triplets which will be
374 loaded on the respective channel when such MIDI program change
375 messages arrive, beside that, each entry allows to define a life-time
376 strategy for the instrument, so the user can define whether the
377 instrument should i.e. be permanently loaded (to be able to switch
378 quickly among sounds) or i.e. loaded just on demand when the
379 respective program change arrives (to safe RAM space), as well as a
380 global volume factor for each entry, so the user can adjust the volume
381 dynamic of his mapped instrument collection without having to modify
382 the instrument files, also one can manage arbitrary amount of such
383 MIDI instrument maps and assign each sampler channel individually
384 a certain map, so that i.e. separation of normal instruments and
385 drumkits is possible
386 - new notification events for tracking changes to audio/MIDI devices,
387 MIDI instrument maps, MIDI instruments, FX sends, global volume.
388 - sampler was limited to load max. 200 instruments in the background
389 due to a constant size RingBuffer FIFO which is now replaced by a
390 dynamic (unlimited) size std::list FIFO
391 - added FX sends, these allow to route audio signals to arbitrary audio
392 output channels for being processed by external effect processors
393 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
394 controllers
395 - global (sampler wide) volume can now be controlled at runtime
396 - Implemented new, improved notification system
397 - fixed compilation errors regarding OSX
398 (patch by Toshi Nagata)
399 - implemented instruments database
400 - added support for escape sequences to the instruments database
401 - added highly experimental support for on-the-fly instrument editing
402 within the sampler's process (by using instrument editor plugins),
403 you'll notice the new "Registered instrument editors:" message on
404 startup, added a new LSCP command:
405 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
406 to spawn a matching instrument editor for the instrument on the
407 given sampler channel, the plugin path can be overridden at compile
408 time with ./configure --enable-plugin-dir=/some/dir
409 - added experimental code for synchronizing instrument editors hosted
410 in the sampler's process to safely edit instruments while playing
411 without a crash (hopefully) by either suspending single regions
412 wherever possible or if unavoidable whole engine(s)
413 - fixed several issues in fundamental "Thread" class: set scheduling
414 policy and priority on thread level, set a minimum stack size for
415 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
416 threads simply inherited properties of starting thread instead of
417 setting their own policy and priority
418 - minor fix in our automatic stack trace mechanism on crashes, the
419 main process did not wait for the stack trace process to finish
420 its output
421 - fixed some minor memory leaks
422 - reenabled assembly features support, at the moment only for
423 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
424 - minor assembly fix in x86 features detection (don't use the PIC
425 register, to avoid relocations in the text segment at runtime)
426 - POSIX callback functions of Thread.h are hidden
427
428 * MIDI driver:
429 - dispatch bank select (MSB and LSB) messages
430
431 * audio driver:
432 - the ALSA audio output driver parameters now reflect the correct
433 parameter value ranges for the respective selected sound card
434 (patch by Till Wimmer, a bit fixed and extended)
435
436 * Gigasampler format engine:
437 - if a filter is used and EG2 finishes before EG1, let the voice
438 die when EG2 has finished (this fixes a problem with clicks and
439 voice starvation for some gigs)
440 - playback is no longer disabled during instrument loading
441 - all notes playing on a channel that changes its instrument keep
442 playing with the old instrument until they get a note off
443 command
444 - EG fix: a release value of zero could cause noises or crash
445 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
446 - EG fine tuning: when attack is zero the EG starts at a level
447 above max sustain level, which means that there is a decay phase
448 even if sustain is 100%
449 - more EG fixes: the level could sometimes go below zero and cause
450 noises or crashes
451 - minor fix of EGDecay (patch by Toshi Nagata)
452 - fixed compiler error when --enable-override-filter-type was
453 supplied to the configure script (fixes #46)
454 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
455 instead of a fix value
456 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
457 127 (solo mode) only kill voices if the respective mode really
458 changed
459
460 * LSCP server:
461 - fixed compile time error for old Bison versions
462 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
463 - parser now supports extended ASCII character set
464 (up to ASCII code 255, i.e. includes now umlauts and accents)
465 - filename arguments in LSCP commands now allow to use escape
466 sequences, that is directly literal as one of: \', \", \\, \n, \r,
467 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
468 code value like \xf2) (fixes bug #24)
469 - the following LSCP commands now also support escape sequences for at
470 least one of their text-based parameters (i.e. name, description):
471 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
472 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
473 "SET DB_INSTRUMENT_DIRECTORY NAME",
474 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
475 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
476 "FIND DB_INSTRUMENT_DIRECTORIES"
477 - returns verbose syntax errors (line and column where syntax error
478 occured, the unexpected character and the actually expected, possible
479 character(s), the latter only if less than 5 possibilities)
480 - made sure that LSCP syntax is not affected by gigedit locale
481 settings
482 - bugfix regarding strings parameter lists: all comma separated lists
483 of strings were treated as being one string containing commas
484 (fixes #57)
485
486 * Bug fixes:
487 - fixed crash occurring on certain LSCP scripts (Bug 39)
488 - another thread safety fix for lscp "load engine" and "set
489 channel audio output device"
490 - fixed a crash which occurs when reassigning the same engine
491 on a sampler channel with connected MIDI device
492 - fixed a crash which occurs when changing the number of ports of a MIDI
493 device connected to a sampler channel to number less then or equal
494 to the index of the port to which the sampler channel is connected.
495 - The previous bindings were not been disconnected when altering
496 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
497 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
498 - The active stream/voice count statistic was incorrect.
499 - notification events were not been sent for some sampler
500 channel changes
501 - added default min and max values to restrict the number of allowed
502 audio output channels and MIDI input ports
503 - the connection to the PCM interface is now closed when destroying
504 an audio output device
505 - files with slash in their path or filename could not be loaded
506
507 * test cases:
508 - updated and fixed (haven't been touched in a while)
509
510 Version 0.4.0 (24 November 2006)
511
512 * packaging changes:
513 - changed deprecated copyright attribute to license; added ldconfig
514 to post-(un)install steps; added devel package for liblinuxsampler;
515 to linuxsampler.spec (RPM)
516 - install necessary development header files for allowing 3rd party
517 applications to link against liblinuxsampler
518 - liblinuxsampler's API documentation can be generated with 'make docs'
519 (Doxygen required)
520 - added benchmark to automatically detect the best triangle LFO
521 implementation (currently either an integer math solution or a
522 di-harmonic approximation), automatic detection can be overriden
523 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
524 configure script argument though (mandatory for cross-compilation)
525 - do not automatically pick optimized gcc flags if the user already
526 provided some on his own (as CXXFLAGS)
527 - added compile time option to disable processing of All-Notes-Off MIDI
528 messages
529 - added compile time options to allow disabling the various audio and
530 MIDI drivers
531 - fixed automatic GCC CPU switch detection on PPC
532 (patch by Ebrahim Mayat)
533
534 * Gigasampler format engine:
535 - extensive synthesis optimization
536 (reimplementation of EGs and LFO(s), removed synthesis parameter
537 prerendering and the synthesis parameter matrix in general, splitting
538 each audio fragment into subfragments now where each subfragment uses
539 constant pitch and filter coefficients. The volume coefficient is
540 linearly interpolated inside a subfragment, unless
541 --disable-interpolate-volume is set.)
542 - fine tuning of the EG modulation parameters
543 - improved filter cutoff calculation by adding support for the
544 following gig parameters: Cutoff freq (used when no cutoff
545 controller is defined), Control invert, Minimum cutoff, Velocity
546 curve and Velocity range. The keyboard tracking now scales
547 cutoff frequency instead of resonance.
548 - added support for gig parameter Resonance.
549 - fixed bug in sysex handling (patch by Juan Linietsky)
550 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
551 which can be overridden with --enable-global-attenuation
552 - EG fixes: made the length of "attack hold" stage more
553 accurate. Release stage can now start before attack stage
554 ends. Cancel release didn't work when sustain was zero. Attack
555 time now has a minimal value to prevent clicks.
556 - fixed pitch changes larger than one octave
557 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
558 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
559 all modes can be altered via standard GM messages, that is CC5 for
560 altering portamento time, CC65 for enabling / disabling portamento
561 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
562 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
563 parameter) and crossfade
564 - added support for the "attenuation controller threshold" gig
565 parameter
566 - added smoothing of volume changes caused by control change
567 messages
568 - sample loop parameters are now taken from the DimensionRegion
569 instead of the wave chunk
570 - fixed keyswitching for v3 gigs with a number of keyswitch splits
571 not equal to a power of two
572 - reimplementation of the filter algorithm. The new filter is more
573 accurate and supports all gig filter types, including bandreject
574 and lowpass turbo.
575 - real support for 24 bit samples - samples are not truncated to
576 16 bits anymore
577 - support for aftertouch (channel pressure, not polyphonic
578 aftertouch)
579 - LFO1 behaviour fixed (dampening from max volume instead of
580 amplifying from 0)
581
582 * LSCP server:
583 - fixed application exit on broken pipe error (fixes bug #20)
584 - fixed the notification messages delay due to lack of
585 network activity (fixes bug #26)
586 - fixed parser bug which occured on space(s) within device parameters
587 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
588
589 * audio driver:
590 - added aRts audio output driver (by no means RT safe)
591
592 * MIDI driver:
593 - fixed legacy sysex code which caused dispatching of MIDI SysEx
594 messages several times instead of once
595 - API extension for MIDI drivers which already supply exact time stamps
596 for events (i.e. for offline rendering based MIDI drivers)
597 - added checks for bad MIDI data
598
599 * linuxsampler application:
600 - show available sampler engine types on startup
601
602 * general changes:
603 - support for muting sampler channels and solo mode of the same, two new
604 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
605 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
606 introduced for this, the behavior is the same like on a mixer console
607 (patch by Grigor Iliev, a bit adjusted). Also added configure option
608 --enable-process-muted-channels which can be used to enable the
609 processing of muted channels.
610 - support for sostenuto pedal
611 - support for monitoring the total number of active voices
612 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
613 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
614 - fixed some memory management errors
615 - fixed some concurrency problems that could lead to crashes when
616 LSCP commands were executed
617 - fixed crash when instrument loading failed previously on the same
618 sampler channel (fixes bug #36)
619
620 Version 0.3.3 (15 July 2005)
621
622 * packaging changes:
623 - fixed compilation with gcc 4.0
624
625 * Gigasampler format engine:
626 - LFO preprocessing was performed even though the respective LFO was
627 disabled by the instrument patch (minor efficiency fix)
628 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
629 for volume ramp downs in the same fragment (needed for current voice
630 stealing implementation) then simply inform the user with a warning
631 about possible click sounds and reduce the volume ramp down
632 appropriately instead of cancelling the audio device connection
633
634 Version 0.3.2 (24 June 2005)
635
636 * packaging changes:
637 - updated autotools build files to compile on OS X
638 (conditional compilation of CoreMIDI and MidiShare drivers)
639 - hand-crafted assembly optimization code can be disabled with
640 './configure --disable-asm' (definitely not recommended)
641 - fixed 'make dist' rule to include all necessary files
642 - require automake (>= 1.5) for 'make -f Makefile.cvs'
643 (due to 'dist-bzip2' automake option)
644
645 * Gigasampler format engine:
646 - support for the gig parameters for "release velocity response" curves
647 - fine tuning of the EGADSR envelope
648 - volume of release triggered samples now depends on note-on velocity,
649 note length and gig parameter "release trigger decay" instead of
650 note-off velocity.
651 - revised voice stealing
652 (fixes crash and endless loop caused by voice stealing)
653 - don't reset scale tuning on instrument or audio output device change
654 - handle key group conflicts right at the beginning of each fragment
655 instead of when the respective voice is actually launched
656 (fixes undefined behavior if stolen voices belonged to a key group -
657 this case was followed by a "killed voice survived" error message)
658 - fixed minor issue with null/silence samples
659 (those stole voices even though they don't need a voice at all which
660 resulted in "voice stealing didn't work out" messages)
661 - don't reset volume, pan, pitch and MIDI controller values on
662 instrument or audio output device change
663
664 * LSCP server:
665 - fixed some crashes (patch by Grigor Iliev, fixes #19)
666 - fixed LSCP event "CHANNEL_INFO" notification
667 (e.g. did not notify on volume changes or MIDI program change events)
668
669 * linuxsampler application:
670 - added command line parameters --lscp-addr and --lscp-port to override
671 default IP address and port of LSCP server
672
673 Version 0.3.1 (24 May 2005)
674
675 * initial release
