* plugin changes:
    - LV2 Persist + Files support (patch by David Robillard)

1 Version CVS HEAD (?)
3 * plugin changes:
4 - LV2 Persist + Files support (patch by David Robillard)
6 * packaging changes:
7 - fixed building with newer MinGW-w64
9 * general changes:
10 - Refactoring: moved the independent code from
11 the Gigasampler format engine to base classes
12 - command line option '--profile' is currently disabled, since the
13 respective profiling code is currently broken
14 - Introduced support for optional environment variable
15 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
16 where the sampler shall look for instrument editor plugins
17 (patch by Luis Garrido, slightly modified).
18 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
19 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
20 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
21 note (in this implementation of the sampler its simply hard routed to
22 the 1st effect send of the sampler channel, no matter what the actual
23 effect type is)
24 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
25 note (in this implementation of the sampler its simply hard routed to
26 the 2nd effect send of the sampler channel, no matter what the actual
27 effect type is)
28 - implemented support for internal LADSPA effects
29 - raised limit of program change queue from 100 to 512
30 (as suggested by Alex Stone)
32 * Gigasampler format engine:
33 - implemented the "round robin keyboard" dimension
34 - fixed round robin and random dimensions for cases when number of
35 dimension zones is not a power of two
36 - made round robin use a counter for each region instead of each
37 key
39 * SFZ format engine:
40 - Initial implementation (not usable yet)
41 - added support for v2 multiple stage envelope generators
42 - added a fine-tuned v1 envelope generator instead of using the
43 one from the gig engine
44 - fixed memory leak and memory handling errors
45 - added support for trigger=first, trigger=legato and sw_previous
46 - allow non-numerical key values ("C#4" for example)
47 - "key" opcode now sets pitch_keycenter too
48 - fixed error when unloading instrument with same sample used by
49 multiple regions
50 - added some opcode aliases, like loopmode for loop_mode, to be
51 more compatible
52 - added support for trigger=release and rt_decay
53 - added support for off_mode=normal
54 - added support for random, seq_position, seq_length and volume
55 - added v1 LFO opcodes to parser (no support in engine yet)
56 - added support for amp_veltrack and amp_velcurve_N
57 - fine-tuned the default velocity curve
58 - added support for transpose
59 - fixed crash when using sw_down/up
60 - improved logic for sw_lokey/hikey/up/down/last
61 - added more v1 aliases to parser
62 - reduced memory usage for sfz data
63 - RT-safeness: avoid malloc in audio thread
64 - fixed a bug that could cause voice stealing to fail

69 - added support for loop_mode=one_shot
70 - fixed playback of 16 bit wav files on big endian CPUs
71 - added support for Ogg Vorbis sample files
72 - use loop markers from sample file if loop_start and loop_end are
73 not set in sfz file
75 * SoundFont format engine:
76 - Initial implementation (not usable yet)
77 - RT-safeness: avoid malloc in audio thread
78 - fixed a bug that could cause voice stealing to fail
80 * Host plugins:
81 - AU bugfix: failed to destroy its audio/MIDI devices
82 - Listen to all interfaces on Mac OS X (INADDR_ANY)
83 - VST bugfix: If the host called resume() before and after
84 changing sample rate or block size, the number of channels was
85 incorrectly set to two. This caused silence in Cubase 5.
86 - save engine type (gig, sfz or sf2) in plugin state
87 - VST: when opening Fantasia, look for both 32 and 64 bit Java on
88 64 bit Windows
90 * MIDI driver:
91 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
92 the ALSA sequencer client name
93 - removed limit of maximum amount of MIDI ports per MIDI device, since
94 there is no reason for this limit

116 - added LSCP command
117 "REMOVE SEND_EFFECT_CHAIN <audio-device> <effect-chain>"
118 - added LSCP command
119 "GET SEND_EFFECT_CHAIN INFO <audio-device> <effect-chain>"

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