* sfz engine: use loop markers from sample file if loop_start and
  loop_end are not set in sfz file

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 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
16 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
17 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
18 note (in this implementation of the sampler its simply hard routed to
19 the 1st effect send of the sampler channel, no matter what the actual
20 effect type is)
21 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
22 note (in this implementation of the sampler its simply hard routed to
23 the 2nd effect send of the sampler channel, no matter what the actual
24 effect type is)
25 - implemented support for internal LADSPA effects
26 - raised limit of program change queue from 100 to 512
27 (as suggested by Alex Stone)
28
29 * Gigasampler format engine:
30 - implemented the "round robin keyboard" dimension
31 - fixed round robin and random dimensions for cases when number of
32 dimension zones is not a power of two
33 - made round robin use a counter for each region instead of each
34 key
35
36 * SFZ format engine:
37 - Initial implementation (not usable yet)
38 - added support for v2 multiple stage envelope generators
39 - added a fine-tuned v1 envelope generator instead of using the
40 one from the gig engine
41 - fixed memory leak and memory handling errors
42 - added support for trigger=first, trigger=legato and sw_previous
43 - allow non-numerical key values ("C#4" for example)
44 - "key" opcode now sets pitch_keycenter too
45 - fixed error when unloading instrument with same sample used by
46 multiple regions
47 - added some opcode aliases, like loopmode for loop_mode, to be
48 more compatible
49 - added support for trigger=release and rt_decay
50 - added support for off_mode=normal
51 - added support for random, seq_position, seq_length and volume
52 - added v1 LFO opcodes to parser (no support in engine yet)
53 - added support for amp_veltrack and amp_velcurve_N
54 - fine-tuned the default velocity curve
55 - added support for transpose
56 - fixed crash when using sw_down/up
57 - improved logic for sw_lokey/hikey/up/down/last
58 - added more v1 aliases to parser
59 - reduced memory usage for sfz data
60 - RT-safeness: avoid malloc in audio thread
61 - fixed a bug that could cause voice stealing to fail
62 - optimized sample lookup
63 - improved support for exclusive groups (group, off_by and
64 off_mode)
65 - added support for controller triggered regions (on_locc/on_hicc)
66 - added support for loop_mode=one_shot
67 - fixed playback of 16 bit wav files on big endian CPUs
68 - added support for Ogg Vorbis sample files
69 - use loop markers from sample file if loop_start and loop_end are
70 not set in sfz file
71
72 * SoundFont format engine:
73 - Initial implementation (not usable yet)
74 - RT-safeness: avoid malloc in audio thread
75 - fixed a bug that could cause voice stealing to fail
76
77 * Host plugins:
78 - AU bugfix: failed to destroy its audio/MIDI devices
79 - Listen to all interfaces on Mac OS X (INADDR_ANY)
80 - VST bugfix: If the host called resume() before and after
81 changing sample rate or block size, the number of channels was
82 incorrectly set to two. This caused silence in Cubase 5.
83 - save engine type (gig, sfz or sf2) in plugin state
84 - VST: when opening Fantasia, look for both 32 and 64 bit Java on
85 64 bit Windows
86
87 * MIDI driver:
88 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
89 the ALSA sequencer client name

130 - fixed crash which occured when changing an already deployed sampler
131 channel to a different engine type
132 - fixed crash when deleting a sampler channel or changing engine
133 type while an instrument load was in progress
134 - bugfix: playing a note while changing the instrument could cause
135 a crash, or give "Handing back unknown region" error messages
136 - bugfix: calling SET VOICES (which Fantasia does on start and
137 refresh) could cause instruments to be unloaded
138
139 Version 1.0.0 (31 July 2009)
140
141 * packaging changes:
142 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
143 causing e.g. the libgig test to fail when
144 "./configure --disable-jack-driver" was used
145 (patch by Alexis Ballier)
146 - fixed compilation with gcc 4.3
147 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
148 - fixed configure so it detects x86_64 (#107)
149 - fixes for building with newer MinGW versions
150 - fix for building with bison 2.4 (#111)
151 - fixed building with libgig installed in a non-standard directory
152 - minor fix in configure for mmsystem.h detection on MinGW
153 - Windows: look for editor plugins and Fantasia using base
154 directory of liblinuxsampler dll (look in the same directory and one
155 directory above)
156 - configure script fix: removed unconditional use of SSE
157 - fixed building with sqlite installed in a non-standard directory
158 - when cross-compiling, don't try to create instruments.db
159 - fix for new mingw-w64 version, which has usleep
160
161 * general changes:
162 - bugfix: on some POSIX systems instrument editor plugins refused to
163 load as we used a non-portable Linux specific struct field
164 (fixes bug #70, patch by Ronald Baljeu)
165 - fixed endless loop which occured when loading an instrument editor
166 plugin DLL on Windows systems failed
167 - fixed memory leaks that occurred when liblinuxsampler was unloaded
168 - optimized the SynchronizedConfig class so it doesn't wait
169 unnecessarily long after an update
170 - added support for notifying instrument editors on note-on / note-off
171 events (e.g. to highlight the pressed keys on the virtual keyboard
172 of gigedit)
173 - added support for triggering notes by instrument editors (see above)
174 - be verbose on DLL load errors (on Linux)
175 - fixed di-harmonic triangle LFO implementation (this LFO implementation
176 is only used by very few systems, most pick the int math
177 implementation, which is usually faster)
178 - fixes for audio drivers with varying buffer sizes
179 - experimental support for running LinuxSampler as a DSSI, LV2 and
180 VST plugin
181 - notification events for stream/voice count statistics are now sent
182 only when there are actual changes
183 - added memory ordering constraints to improve stability on
184 multi-core and multi-cpu systems
185 - maximum voices and disk streams can now be altered at runtime
186 - fixed CPU feature detection on x86_64 (maybe fixes #108)
187 - automatic stacktrace mechanism is now turned off by default and can
188 be switched on by command line option "--stacktrace" (the automatic
189 stacktrace mechanism seems to be broken on most systems at the moment)
190 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
191 a pointer to the launched InstrumentEditor object
192 - added optional 3rd party user data parameter for following
193 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
194 InstrumentEditor::Launch(),
195 InstrumentManager::LaunchInstrumentEditor()
196 - theoretical fix: made SynchronizedConfig follow C++0x memory
197 model more strictly
198 - fixes for using large audio device buffers
199 - Windows: add the installation directory to the DLL search path
200 when loading an editor plugin (solves problems with VST and
201 gigedit on systems with other GTK versions installed)
202
203 * audio driver:
204 - removed the nonsense audio channel constraint (which was hard coded to
205 max. 100 audio channels) for most audio drivers
206 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
207 opposed to the LSCP specs
208 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
209 reflected the wrong value
210 - fixed a memory management bug in ASIO driver
211 - Makefile fix: JACK_CFLAGS wasn't used
212 - JACK: use jack_client_open instead of the deprecated
213 jack_client_new
214 - added (experimental) CoreAudio driver
215 - applied old fixes to the ASIO driver that were included in the
216 previous binary release but accidentally never committed to CVS
217 (fixes #117)
218 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
219 win64)
220 - VST: added support for sample rate and buffer size changes
221 - VST: close editor (Fantasia) when the VST is removed
222 - VST: avoid opening Fantasia more than once for each VST instance
223 - VST: export main function as "main" on Linux too (fix for
224 energyXT)
225 - VST: changed number of output channels from one stereo to 16
226 stereo
227 - added channel routing, fxsends and midi maps to the settings
228 stored in the plugin state
229 - performance optimization of AudioChannel::MixTo() and
230 AudioChannel::CopyTo() methods using GCC vector exensions
231 (if available)
232 - ASIO fixes: avoid initializing the device twice, avoid throwing
233 exception when getting parameters from a disconnected device
234
235 * MIDI driver:
236 - added JACK MIDI driver
237 - dispatch bank select as ordinary CC as well, the user might seriously
238 want to (mis)use it for some purpose ("fixed" in all current MIDI
239 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
240 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
241 CoreMidi or AU
242 - fixed mingw-w64 compilation error in MME driver
243 - made program change handling in MIDI thread real-time safe by
244 moving the logic to a non-RT thread
245 - fixed minor memory leak in ALSA driver
246
247 * instruments database:
248 - avoid time consuming samples scanning when adding instruments
249 to the instruments database
250 - added support for handling lost files in the instruments database
251 - Implemented option for adding instruments in separate directories
252 in the instruments database
253 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
254 - work-around for missing fnmatch function on Windows to make
255 instrument database compilable
256 - added instrument database support on Windows
257 works with both standalone mode and VST plugin.
258 the instruments DB file is located in
259 %USERPROFILE%\.linuxsampler\instruments.db which allows different
260 databases for each windows user
261 if no DB is present it automatically creates the .linuxsampler subdir
262 and then creates an empty DB
263 - fixed recursive import, which was broken on Windows
264
265 * Gigasampler format engine:
266 - fixed a memory leak that could happen when a channel was deleted
267 while notes were playing
268 - made it possible to load an instrument even if the audio thread
269 isn't running
270 - added partial support for the "Controller Triggered" MIDI rule,
271 enough for piano gigs with pedal noise samples
272 - minor fix: only mark FX sends as being modified if really the
273 respective FX send MIDI controller was used
274 - added support for GM global device volume SysEx message
275 (can be selected at compile time to either apply globally to the
276 whole sampler [default] or only to the sampler channels that are
277 connected to the respective MIDI input port the SysEx message arrived
278 on)
279 - bugfix: notes triggered at position 0 in the audio buffer were
280 sometimes wrongly killed in the same buffer, causing no sound to
281 be played
282 - added support for chromatic / drumkit mode Roland GS Sysex message
283 which is usally used to switch a part between chromatic sounds and
284 drumkit sounds (as opposed to their common default setting of MIDI
285 part 10 being a drumkit part and all other ones chromatic parts), in
286 LS however one can switch between the first 16 MIDI instrument maps
287 defined for the sampler
288 - made it possible to create multiple sample channels even if the
289 audio thread isn't running
290 - fixed crash when removing channel with active voices (#116)
291 - bugfix: on sample reference changes (instrument editor), only
292 un-cache the respective sample if it's really not used by any
293 sampler engine anymore
294 - re-cache samples in case they were changed by an instrument editor,
295 e.g. when a sample was added while playing (#82)
296 - fixed hanging notes which occured when note-off event had the exact
297 same time stamp as the voice's note-on event and occured both in the
298 same audio fragment cycle (fixes bug #112)
299 - added support for the "fine tune" and "pitch bend range"
300 instrument-level gig parameters
301 - fixed minor artifacts in pitch bend handling
302 - added support for GS Reset SysEx message
303 - allow gig files to use unlimited downward pitch shifting
304 - added a limit check for upward pitch shifting
305 - bugfix: sometimes, when playing a note twice fast, the second
306 note was silent
307 - fixed crash happening when a pitch bend event arrived at the
308 same time a new instrument was loading
309
310 * LSCP server:
311 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
312 react on MIDI data arriving on certain sampler channels (so far only
313 Note-On and Note-Off events are sent via this LSCP event)
314 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
315 react on MIDI data arriving on certain MIDI input devices (so far only
316 Note-On and Note-Off events are sent via this LSCP event)
317 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
318 SET DB_INSTRUMENT FILE_PATH
319 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
320 frontends to send MIDI messages to specific sampler channel
321 - added two additional fields to GET FILE INSTRUMENT INFO command -
322 KEY_BINDINGS and KEYSWITCH_BINDINGS
323 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
324 was incorrect
325 - Optimized the retrieval of the MIDI instrument mappings
326 - added new LSCP command "SET VOICES" to globally alter the maximum
327 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
328 be triggered respectively
329 - added new LSCP command "SET STREAMS" to globally alter the maximum
330 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
331 which will be triggered respectively
332 - bugfix: retry if "select" returns EINTR (this fixes a crash when
333 a gigedit file dialog is opened)
334 - close all connections when LSCPServer is deleted
335 - hard close of all sockets on exit
336 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
337 driver
338
339 * Bug fixes:
340 - fixed a crash which occurs when removing a sampler channel waiting
341 to start instrument loading after another channel
342 - fixed a crash which occurs when removing a sampler channel with
343 instrument loading in progress (bug #113)
344 - fixed termination caused by uncaught exception when adding MIDI
345 instrument with PERSISTENT load mode
346 - fixed possible iterator invalidations when resetting the sampler
347 - fixed memory leaks when issuing the following LSCP commands:
348 GET AUDIO_OUTPUT_DRIVER INFO
349 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
350 GET MIDI_INPUT_DRIVER INFO
351 GET MIDI_INPUT_DRIVER_PARAMETER INFO
352 - fixed possible compilation error when sqlite is not present
353 - fixed orphaned pointers when setting maximum voices limit (bug #118)
354 - fixed crash when changing the audio output device of a sampler
355 channel with loaded instrument and start playing notes
356 - fixed endless loop in Engine::SuspendAll() (bug #120)
357 - fixed a low-level atomic load function that was broken on 64-bit
358 PowerPC, which probably could cause crashes on that platform
359 - fixed a memory management error which could cause a crash when a
360 plugin was unloaded
361 - bugfix: two private structs had the same name, which could cause
362 problems if the linker chose the wrong constructor
363 - fixed low-level ConditionServer usage bug that caused lockups on
364 Windows
365
366
367 Version 0.5.1 (6 December 2007)
368
369 * packaging changes:
370 - added autoconf checks for pthread library
371 - added autoconf check for pthread bug found on certain NPTL-enabled
372 glibc versions (see Gentoo bug report #194076)
373 - added autoconf checks for MS Windows
374
375 * general changes:
376 - bugfix: the thread used by an editor plugin didn't die when the
377 editor closed
378 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
379 out all the space. operator--() did not apply size_mask after
380 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
381 order to avoid problems with the _NonVolatileReader functions.
382 - bugfix: Stream.h: added a missing divide by BytesPerSample in
383 GetWriteSpace(). Since this function is currently only used in
384 the stream's qsort() compare function, it didn't trigger any
385 bugs.
386 - Resampler.h, Synthesizer.h: cubic interpolation now works in
387 24bit mode too. Faster method to read 24bit words on little
388 endian machines (x86): replaced 3 byte reads + shifts with a 1
389 unaligned 32bit read and shift
390 - experimental support for MS Windows (MIDI input via MME, AUDIO
391 output via ASIO)
392 - made handling of SIGINT signal (Ctrl-C) a bit more robust
393 - support for monitoring the total number of active disk streams
394 (new LSCP commands: GET TOTAL_STREAM_COUNT,
395 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
396
397 * AUDIO driver:
398 - added Windows ASIO low latency audio driver
399
400 * MIDI driver:
401 - added MME Windows MIDI driver
402
403 * LSCP server:
404 - added support for Windows style path / filenames, however with
405 forward slash path separators instead of backslash
406 (i.e. "C:/foo/bar.gig")
407 - allow naughty liblscp to send non-string device parameters within
408 apostrophes as well
409 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
410 "LIST FILE INSTRUMENTS <file>" and
411 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
412 about an arbitrary instrument file on the system where the sampler is
413 running on
414
415 Version 0.5.0 (15 October 2007)
416
417 * packaging changes:
418 - config.h is not going to be installed along with liblinuxsampler's
419 API header files anymore
420 - only the API relevant header (and source) files will be exported to
421 the Doxygen API documentation (explicitly listed in Doxyfile.in)
422 - added completely new XCode project files for Mac OSX which is now
423 capable to execute our autoconf environment, thus no need anymore
424 to maintain the compile time configuration file (osx/version.h) for
425 OSX manually (patch by Toshi Nagata)
426 - fixed buggy boolean --enable-foo / --disable-foo configure script
427 parameters
428 - global.h now only covers global definitions that are needed for the
429 C++ API header files, all implementation internal global definitions
430 are now in global_private.h
431 - atomic.h is not exposed to the C++ API anymore
432 - no need to include config.h anymore for using LS's API header files
433 - fixed warnings in API doc generation
434
435 * general changes:
436 - replaced the old, confusing MIDI program change mechanism by a
437 flexible MIDI instrument mapper which allows to map arbitrary
438 (MIDI bank, MIDI program) pairs with arbitrary
439 (engine type, instrument file, file index) triplets which will be
440 loaded on the respective channel when such MIDI program change
441 messages arrive, beside that, each entry allows to define a life-time
442 strategy for the instrument, so the user can define whether the
443 instrument should i.e. be permanently loaded (to be able to switch
444 quickly among sounds) or i.e. loaded just on demand when the
445 respective program change arrives (to safe RAM space), as well as a
446 global volume factor for each entry, so the user can adjust the volume
447 dynamic of his mapped instrument collection without having to modify
448 the instrument files, also one can manage arbitrary amount of such
449 MIDI instrument maps and assign each sampler channel individually
450 a certain map, so that i.e. separation of normal instruments and
451 drumkits is possible
452 - new notification events for tracking changes to audio/MIDI devices,
453 MIDI instrument maps, MIDI instruments, FX sends, global volume.
454 - sampler was limited to load max. 200 instruments in the background
455 due to a constant size RingBuffer FIFO which is now replaced by a
456 dynamic (unlimited) size std::list FIFO
457 - added FX sends, these allow to route audio signals to arbitrary audio
458 output channels for being processed by external effect processors
459 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
460 controllers
461 - global (sampler wide) volume can now be controlled at runtime
462 - Implemented new, improved notification system
463 - fixed compilation errors regarding OSX
464 (patch by Toshi Nagata)
465 - implemented instruments database
466 - added support for escape sequences to the instruments database
467 - added highly experimental support for on-the-fly instrument editing
468 within the sampler's process (by using instrument editor plugins),
469 you'll notice the new "Registered instrument editors:" message on
470 startup, added a new LSCP command:
471 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
472 to spawn a matching instrument editor for the instrument on the
473 given sampler channel, the plugin path can be overridden at compile
474 time with ./configure --enable-plugin-dir=/some/dir
475 - added experimental code for synchronizing instrument editors hosted
476 in the sampler's process to safely edit instruments while playing
477 without a crash (hopefully) by either suspending single regions
478 wherever possible or if unavoidable whole engine(s)
479 - fixed several issues in fundamental "Thread" class: set scheduling
480 policy and priority on thread level, set a minimum stack size for
481 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
482 threads simply inherited properties of starting thread instead of
483 setting their own policy and priority
484 - minor fix in our automatic stack trace mechanism on crashes, the
485 main process did not wait for the stack trace process to finish
486 its output
487 - fixed some minor memory leaks
488 - reenabled assembly features support, at the moment only for
489 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
490 - minor assembly fix in x86 features detection (don't use the PIC
491 register, to avoid relocations in the text segment at runtime)
492 - POSIX callback functions of Thread.h are hidden
493
494 * MIDI driver:
495 - dispatch bank select (MSB and LSB) messages
496
497 * audio driver:
498 - the ALSA audio output driver parameters now reflect the correct
499 parameter value ranges for the respective selected sound card
500 (patch by Till Wimmer, a bit fixed and extended)
501
502 * Gigasampler format engine:
503 - if a filter is used and EG2 finishes before EG1, let the voice
504 die when EG2 has finished (this fixes a problem with clicks and
505 voice starvation for some gigs)
506 - playback is no longer disabled during instrument loading
507 - all notes playing on a channel that changes its instrument keep
508 playing with the old instrument until they get a note off
509 command
510 - EG fix: a release value of zero could cause noises or crash
511 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
512 - EG fine tuning: when attack is zero the EG starts at a level
513 above max sustain level, which means that there is a decay phase
514 even if sustain is 100%
515 - more EG fixes: the level could sometimes go below zero and cause
516 noises or crashes
517 - minor fix of EGDecay (patch by Toshi Nagata)
518 - fixed compiler error when --enable-override-filter-type was
519 supplied to the configure script (fixes #46)
520 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
521 instead of a fix value
522 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
523 127 (solo mode) only kill voices if the respective mode really
524 changed
525
526 * LSCP server:
527 - fixed compile time error for old Bison versions
528 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
529 - parser now supports extended ASCII character set
530 (up to ASCII code 255, i.e. includes now umlauts and accents)
531 - filename arguments in LSCP commands now allow to use escape
532 sequences, that is directly literal as one of: \', \", \\, \n, \r,
533 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
534 code value like \xf2) (fixes bug #24)
535 - the following LSCP commands now also support escape sequences for at
536 least one of their text-based parameters (i.e. name, description):
537 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
538 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
539 "SET DB_INSTRUMENT_DIRECTORY NAME",
540 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
541 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
542 "FIND DB_INSTRUMENT_DIRECTORIES"
543 - returns verbose syntax errors (line and column where syntax error
544 occured, the unexpected character and the actually expected, possible
545 character(s), the latter only if less than 5 possibilities)
546 - made sure that LSCP syntax is not affected by gigedit locale
547 settings
548 - bugfix regarding strings parameter lists: all comma separated lists
549 of strings were treated as being one string containing commas
550 (fixes #57)
551
552 * Bug fixes:
553 - fixed crash occurring on certain LSCP scripts (Bug 39)
554 - another thread safety fix for lscp "load engine" and "set
555 channel audio output device"
556 - fixed a crash which occurs when reassigning the same engine
557 on a sampler channel with connected MIDI device
558 - fixed a crash which occurs when changing the number of ports of a MIDI
559 device connected to a sampler channel to number less then or equal
560 to the index of the port to which the sampler channel is connected.
561 - The previous bindings were not been disconnected when altering
562 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
563 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
564 - The active stream/voice count statistic was incorrect.
565 - notification events were not been sent for some sampler
566 channel changes
567 - added default min and max values to restrict the number of allowed
568 audio output channels and MIDI input ports
569 - the connection to the PCM interface is now closed when destroying
570 an audio output device
571 - files with slash in their path or filename could not be loaded
572
573 * test cases:
574 - updated and fixed (haven't been touched in a while)
575
576 Version 0.4.0 (24 November 2006)
577
578 * packaging changes:
579 - changed deprecated copyright attribute to license; added ldconfig
580 to post-(un)install steps; added devel package for liblinuxsampler;
581 to linuxsampler.spec (RPM)
582 - install necessary development header files for allowing 3rd party
583 applications to link against liblinuxsampler
584 - liblinuxsampler's API documentation can be generated with 'make docs'
585 (Doxygen required)
586 - added benchmark to automatically detect the best triangle LFO
587 implementation (currently either an integer math solution or a
588 di-harmonic approximation), automatic detection can be overriden
589 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
590 configure script argument though (mandatory for cross-compilation)
591 - do not automatically pick optimized gcc flags if the user already
592 provided some on his own (as CXXFLAGS)
593 - added compile time option to disable processing of All-Notes-Off MIDI
594 messages
595 - added compile time options to allow disabling the various audio and
596 MIDI drivers
597 - fixed automatic GCC CPU switch detection on PPC
598 (patch by Ebrahim Mayat)
599
600 * Gigasampler format engine:
601 - extensive synthesis optimization
602 (reimplementation of EGs and LFO(s), removed synthesis parameter
603 prerendering and the synthesis parameter matrix in general, splitting
604 each audio fragment into subfragments now where each subfragment uses
605 constant pitch and filter coefficients. The volume coefficient is
606 linearly interpolated inside a subfragment, unless
607 --disable-interpolate-volume is set.)
608 - fine tuning of the EG modulation parameters
609 - improved filter cutoff calculation by adding support for the
610 following gig parameters: Cutoff freq (used when no cutoff
611 controller is defined), Control invert, Minimum cutoff, Velocity
612 curve and Velocity range. The keyboard tracking now scales
613 cutoff frequency instead of resonance.
614 - added support for gig parameter Resonance.
615 - fixed bug in sysex handling (patch by Juan Linietsky)
616 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
617 which can be overridden with --enable-global-attenuation
618 - EG fixes: made the length of "attack hold" stage more
619 accurate. Release stage can now start before attack stage
620 ends. Cancel release didn't work when sustain was zero. Attack
621 time now has a minimal value to prevent clicks.
622 - fixed pitch changes larger than one octave
623 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
624 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
625 all modes can be altered via standard GM messages, that is CC5 for
626 altering portamento time, CC65 for enabling / disabling portamento
627 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
628 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
629 parameter) and crossfade
630 - added support for the "attenuation controller threshold" gig
631 parameter
632 - added smoothing of volume changes caused by control change
633 messages
634 - sample loop parameters are now taken from the DimensionRegion
635 instead of the wave chunk
636 - fixed keyswitching for v3 gigs with a number of keyswitch splits
637 not equal to a power of two
638 - reimplementation of the filter algorithm. The new filter is more
639 accurate and supports all gig filter types, including bandreject
640 and lowpass turbo.
641 - real support for 24 bit samples - samples are not truncated to
642 16 bits anymore
643 - support for aftertouch (channel pressure, not polyphonic
644 aftertouch)
645 - LFO1 behaviour fixed (dampening from max volume instead of
646 amplifying from 0)
647
648 * LSCP server:
649 - fixed application exit on broken pipe error (fixes bug #20)
650 - fixed the notification messages delay due to lack of
651 network activity (fixes bug #26)
652 - fixed parser bug which occured on space(s) within device parameters
653 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
654
655 * audio driver:
656 - added aRts audio output driver (by no means RT safe)
657
658 * MIDI driver:
659 - fixed legacy sysex code which caused dispatching of MIDI SysEx
660 messages several times instead of once
661 - API extension for MIDI drivers which already supply exact time stamps
662 for events (i.e. for offline rendering based MIDI drivers)
663 - added checks for bad MIDI data
664
665 * linuxsampler application:
666 - show available sampler engine types on startup
667
668 * general changes:
669 - support for muting sampler channels and solo mode of the same, two new
670 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
671 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
672 introduced for this, the behavior is the same like on a mixer console
673 (patch by Grigor Iliev, a bit adjusted). Also added configure option
674 --enable-process-muted-channels which can be used to enable the
675 processing of muted channels.
676 - support for sostenuto pedal
677 - support for monitoring the total number of active voices
678 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
679 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
680 - fixed some memory management errors
681 - fixed some concurrency problems that could lead to crashes when
682 LSCP commands were executed
683 - fixed crash when instrument loading failed previously on the same
684 sampler channel (fixes bug #36)
685
686 Version 0.3.3 (15 July 2005)
687
688 * packaging changes:
689 - fixed compilation with gcc 4.0
690
691 * Gigasampler format engine:
692 - LFO preprocessing was performed even though the respective LFO was
693 disabled by the instrument patch (minor efficiency fix)
694 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
695 for volume ramp downs in the same fragment (needed for current voice
696 stealing implementation) then simply inform the user with a warning
697 about possible click sounds and reduce the volume ramp down
698 appropriately instead of cancelling the audio device connection
699
700 Version 0.3.2 (24 June 2005)
701
702 * packaging changes:
703 - updated autotools build files to compile on OS X
704 (conditional compilation of CoreMIDI and MidiShare drivers)
705 - hand-crafted assembly optimization code can be disabled with
706 './configure --disable-asm' (definitely not recommended)
707 - fixed 'make dist' rule to include all necessary files
708 - require automake (>= 1.5) for 'make -f Makefile.cvs'
709 (due to 'dist-bzip2' automake option)
710
711 * Gigasampler format engine:
712 - support for the gig parameters for "release velocity response" curves
713 - fine tuning of the EGADSR envelope
714 - volume of release triggered samples now depends on note-on velocity,
715 note length and gig parameter "release trigger decay" instead of
716 note-off velocity.
717 - revised voice stealing
718 (fixes crash and endless loop caused by voice stealing)
719 - don't reset scale tuning on instrument or audio output device change
720 - handle key group conflicts right at the beginning of each fragment
721 instead of when the respective voice is actually launched
722 (fixes undefined behavior if stolen voices belonged to a key group -
723 this case was followed by a "killed voice survived" error message)
724 - fixed minor issue with null/silence samples
725 (those stole voices even though they don't need a voice at all which
726 resulted in "voice stealing didn't work out" messages)
727 - don't reset volume, pan, pitch and MIDI controller values on
728 instrument or audio output device change
729
730 * LSCP server:
731 - fixed some crashes (patch by Grigor Iliev, fixes #19)
732 - fixed LSCP event "CHANNEL_INFO" notification
733 (e.g. did not notify on volume changes or MIDI program change events)
734
735 * linuxsampler application:
736 - added command line parameters --lscp-addr and --lscp-port to override
737 default IP address and port of LSCP server
738
739 Version 0.3.1 (24 May 2005)
740
741 * initial release
