1 Version CVS HEAD (?)
2
3 * plugin changes:
4 - LV2 Persist + Files support (patch by David Robillard)
5
6 * packaging changes:
7 - fixed building with newer MinGW-w64
8 - Mac OS X: support the new dir for Core Audio SDK
9 - Mac OS X: fixed building outside source directory
10 - made sure all source files for hostplugins are included when
11 doing "make dist"
12 - removed empty directories left from the cvs to svn migration
13 - fixed compilation with gcc 4.6.1
14 - another "make dist" fix, for LV2 plugin
15 - made --enable-pthread-testcancel default on Mac OS X
16
17 * general changes:
18 - Refactoring: moved the independent code from
19 the Gigasampler format engine to base classes
20 - command line option '--profile' is currently disabled, since the
21 respective profiling code is currently broken
22 - Introduced support for optional environment variable
23 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
24 where the sampler shall look for instrument editor plugins
25 (patch by Luis Garrido, slightly modified).
26 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
27 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
28 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
29 note (in this implementation of the sampler its simply hard routed to
30 the 1st effect send of the sampler channel, no matter what the actual
31 effect type is)
32 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
33 note (in this implementation of the sampler its simply hard routed to
34 the 2nd effect send of the sampler channel, no matter what the actual
35 effect type is)
36 - implemented support for internal LADSPA effects
37 - raised limit of program change queue from 100 to 512
38 (as suggested by Alex Stone)
39
40 * Gigasampler format engine:
41 - implemented the "round robin keyboard" dimension
42 - fixed round robin and random dimensions for cases when number of
43 dimension zones is not a power of two
44 - made round robin use a counter for each region instead of each
45 key
46
47 * SFZ format engine:
48 - Initial implementation (not usable yet)
49 - added support for v2 multiple stage envelope generators

51 one from the gig engine
52 - fixed memory leak and memory handling errors
53 - added support for trigger=first, trigger=legato and sw_previous
54 - allow non-numerical key values ("C#4" for example)
55 - "key" opcode now sets pitch_keycenter too
56 - fixed error when unloading instrument with same sample used by
57 multiple regions
58 - added some opcode aliases, like loopmode for loop_mode, to be
59 more compatible

81 not set in sfz file
82 - implemeted filters. Filter types: lowpass, bandpass, bandreject
83 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
84 cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
85 cutoff_cc, cutoff_chanaft.
86 - bugfix: zero ampeg_sustain didn't work
87 - added support for velocity effect on amplifier envelope time
88 (ampeg_vel2attack, ampeg_vel2decay, ampeg_vel2sustain and

90
91 * SoundFont format engine:
92 - Initial implementation (not usable yet)
93 - RT-safeness: avoid malloc in audio thread

102 * Host plugins:
103 - AU bugfix: failed to destroy its audio/MIDI devices
104 - Listen to all interfaces on Mac OS X (INADDR_ANY)
105 - VST bugfix: If the host called resume() before and after

107 incorrectly set to two. This caused silence in Cubase 5.
108 - save engine type (gig, sfz or sf2) in plugin state
109 - VST: when opening Fantasia, look for both 32 and 64 bit Java on
110 64 bit Windows

112 * MIDI driver:
113 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
114 the ALSA sequencer client name

156 "SUBSCRIBE SEND_EFFECT_CHAIN_INFO"
157
158 * Bug fixes:
159 - Fixed crash which may occur when MIDI key + transpose is out of range
160 - minor valgrind fixes
161 - fixed crash which occured when changing an already deployed sampler
162 channel to a different engine type
163 - fixed crash when deleting a sampler channel or changing engine
164 type while an instrument load was in progress
165 - bugfix: playing a note while changing the instrument could cause
166 a crash, or give "Handing back unknown region" error messages
167 - bugfix: calling SET VOICES (which Fantasia does on start and
168 refresh) could cause instruments to be unloaded
169 - Mac OS X: fixed name collision of enum in EffectControl and
170 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
171 - Mac OS X: fixed hanging threads
172 - Windows: disabled the previous thread fix on non-Mac systems, as
173 it caused hanging threads on Windows
174
175 Version 1.0.0 (31 July 2009)
176
177 * packaging changes:
178 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
179 causing e.g. the libgig test to fail when
180 "./configure --disable-jack-driver" was used
181 (patch by Alexis Ballier)
182 - fixed compilation with gcc 4.3
183 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
184 - fixed configure so it detects x86_64 (#107)
185 - fixes for building with newer MinGW versions
186 - fix for building with bison 2.4 (#111)
187 - fixed building with libgig installed in a non-standard directory
188 - minor fix in configure for mmsystem.h detection on MinGW
189 - Windows: look for editor plugins and Fantasia using base
190 directory of liblinuxsampler dll (look in the same directory and one
191 directory above)
192 - configure script fix: removed unconditional use of SSE
193 - fixed building with sqlite installed in a non-standard directory
194 - when cross-compiling, don't try to create instruments.db
195 - fix for new mingw-w64 version, which has usleep
196
197 * general changes:
198 - bugfix: on some POSIX systems instrument editor plugins refused to
199 load as we used a non-portable Linux specific struct field
200 (fixes bug #70, patch by Ronald Baljeu)
201 - fixed endless loop which occured when loading an instrument editor
202 plugin DLL on Windows systems failed
203 - fixed memory leaks that occurred when liblinuxsampler was unloaded
204 - optimized the SynchronizedConfig class so it doesn't wait
205 unnecessarily long after an update
206 - added support for notifying instrument editors on note-on / note-off
207 events (e.g. to highlight the pressed keys on the virtual keyboard
208 of gigedit)
209 - added support for triggering notes by instrument editors (see above)
210 - be verbose on DLL load errors (on Linux)
211 - fixed di-harmonic triangle LFO implementation (this LFO implementation
212 is only used by very few systems, most pick the int math
213 implementation, which is usually faster)
214 - fixes for audio drivers with varying buffer sizes
215 - experimental support for running LinuxSampler as a DSSI, LV2 and
216 VST plugin
217 - notification events for stream/voice count statistics are now sent
218 only when there are actual changes
219 - added memory ordering constraints to improve stability on
220 multi-core and multi-cpu systems
221 - maximum voices and disk streams can now be altered at runtime
222 - fixed CPU feature detection on x86_64 (maybe fixes #108)
223 - automatic stacktrace mechanism is now turned off by default and can
224 be switched on by command line option "--stacktrace" (the automatic
225 stacktrace mechanism seems to be broken on most systems at the moment)
226 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
227 a pointer to the launched InstrumentEditor object
228 - added optional 3rd party user data parameter for following
229 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
230 InstrumentEditor::Launch(),
231 InstrumentManager::LaunchInstrumentEditor()
232 - theoretical fix: made SynchronizedConfig follow C++0x memory
233 model more strictly
234 - fixes for using large audio device buffers
235 - Windows: add the installation directory to the DLL search path
236 when loading an editor plugin (solves problems with VST and
237 gigedit on systems with other GTK versions installed)
238
239 * audio driver:
240 - removed the nonsense audio channel constraint (which was hard coded to
241 max. 100 audio channels) for most audio drivers
242 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
243 opposed to the LSCP specs
244 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
245 reflected the wrong value
246 - fixed a memory management bug in ASIO driver
247 - Makefile fix: JACK_CFLAGS wasn't used
248 - JACK: use jack_client_open instead of the deprecated
249 jack_client_new
250 - added (experimental) CoreAudio driver
251 - applied old fixes to the ASIO driver that were included in the
252 previous binary release but accidentally never committed to CVS
253 (fixes #117)
254 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
255 win64)
256 - VST: added support for sample rate and buffer size changes
257 - VST: close editor (Fantasia) when the VST is removed
258 - VST: avoid opening Fantasia more than once for each VST instance
259 - VST: export main function as "main" on Linux too (fix for
260 energyXT)
261 - VST: changed number of output channels from one stereo to 16
262 stereo
263 - added channel routing, fxsends and midi maps to the settings
264 stored in the plugin state
265 - performance optimization of AudioChannel::MixTo() and
266 AudioChannel::CopyTo() methods using GCC vector exensions
267 (if available)
268 - ASIO fixes: avoid initializing the device twice, avoid throwing
269 exception when getting parameters from a disconnected device
270
271 * MIDI driver:
272 - added JACK MIDI driver
273 - dispatch bank select as ordinary CC as well, the user might seriously
274 want to (mis)use it for some purpose ("fixed" in all current MIDI
275 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
276 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
277 CoreMidi or AU
278 - fixed mingw-w64 compilation error in MME driver
279 - made program change handling in MIDI thread real-time safe by
280 moving the logic to a non-RT thread
281 - fixed minor memory leak in ALSA driver
282
283 * instruments database:
284 - avoid time consuming samples scanning when adding instruments
285 to the instruments database
286 - added support for handling lost files in the instruments database
287 - Implemented option for adding instruments in separate directories
288 in the instruments database
289 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
290 - work-around for missing fnmatch function on Windows to make
291 instrument database compilable
292 - added instrument database support on Windows
293 works with both standalone mode and VST plugin.
294 the instruments DB file is located in
295 %USERPROFILE%\.linuxsampler\instruments.db which allows different
296 databases for each windows user
297 if no DB is present it automatically creates the .linuxsampler subdir
298 and then creates an empty DB
299 - fixed recursive import, which was broken on Windows
300
301 * Gigasampler format engine:
302 - fixed a memory leak that could happen when a channel was deleted
303 while notes were playing
304 - made it possible to load an instrument even if the audio thread
305 isn't running
306 - added partial support for the "Controller Triggered" MIDI rule,
307 enough for piano gigs with pedal noise samples
308 - minor fix: only mark FX sends as being modified if really the
309 respective FX send MIDI controller was used
310 - added support for GM global device volume SysEx message
311 (can be selected at compile time to either apply globally to the
312 whole sampler [default] or only to the sampler channels that are
313 connected to the respective MIDI input port the SysEx message arrived
314 on)
315 - bugfix: notes triggered at position 0 in the audio buffer were
316 sometimes wrongly killed in the same buffer, causing no sound to
317 be played
318 - added support for chromatic / drumkit mode Roland GS Sysex message
319 which is usally used to switch a part between chromatic sounds and
320 drumkit sounds (as opposed to their common default setting of MIDI
321 part 10 being a drumkit part and all other ones chromatic parts), in
322 LS however one can switch between the first 16 MIDI instrument maps
323 defined for the sampler
324 - made it possible to create multiple sample channels even if the
325 audio thread isn't running
326 - fixed crash when removing channel with active voices (#116)
327 - bugfix: on sample reference changes (instrument editor), only
328 un-cache the respective sample if it's really not used by any
329 sampler engine anymore
330 - re-cache samples in case they were changed by an instrument editor,
331 e.g. when a sample was added while playing (#82)
332 - fixed hanging notes which occured when note-off event had the exact
333 same time stamp as the voice's note-on event and occured both in the
334 same audio fragment cycle (fixes bug #112)
335 - added support for the "fine tune" and "pitch bend range"
336 instrument-level gig parameters
337 - fixed minor artifacts in pitch bend handling
338 - added support for GS Reset SysEx message
339 - allow gig files to use unlimited downward pitch shifting
340 - added a limit check for upward pitch shifting
341 - bugfix: sometimes, when playing a note twice fast, the second
342 note was silent
343 - fixed crash happening when a pitch bend event arrived at the
344 same time a new instrument was loading
345
346 * LSCP server:
347 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
348 react on MIDI data arriving on certain sampler channels (so far only
349 Note-On and Note-Off events are sent via this LSCP event)
350 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
351 react on MIDI data arriving on certain MIDI input devices (so far only
352 Note-On and Note-Off events are sent via this LSCP event)
353 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
354 SET DB_INSTRUMENT FILE_PATH
355 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
356 frontends to send MIDI messages to specific sampler channel
357 - added two additional fields to GET FILE INSTRUMENT INFO command -
358 KEY_BINDINGS and KEYSWITCH_BINDINGS
359 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
360 was incorrect
361 - Optimized the retrieval of the MIDI instrument mappings
362 - added new LSCP command "SET VOICES" to globally alter the maximum
363 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
364 be triggered respectively
365 - added new LSCP command "SET STREAMS" to globally alter the maximum
366 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
367 which will be triggered respectively
368 - bugfix: retry if "select" returns EINTR (this fixes a crash when
369 a gigedit file dialog is opened)
370 - close all connections when LSCPServer is deleted
371 - hard close of all sockets on exit
372 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
373 driver
374
375 * Bug fixes:
376 - fixed a crash which occurs when removing a sampler channel waiting
377 to start instrument loading after another channel
378 - fixed a crash which occurs when removing a sampler channel with
379 instrument loading in progress (bug #113)
380 - fixed termination caused by uncaught exception when adding MIDI
381 instrument with PERSISTENT load mode
382 - fixed possible iterator invalidations when resetting the sampler
383 - fixed memory leaks when issuing the following LSCP commands:
384 GET AUDIO_OUTPUT_DRIVER INFO
385 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
386 GET MIDI_INPUT_DRIVER INFO
387 GET MIDI_INPUT_DRIVER_PARAMETER INFO
388 - fixed possible compilation error when sqlite is not present
389 - fixed orphaned pointers when setting maximum voices limit (bug #118)
390 - fixed crash when changing the audio output device of a sampler
391 channel with loaded instrument and start playing notes
392 - fixed endless loop in Engine::SuspendAll() (bug #120)
393 - fixed a low-level atomic load function that was broken on 64-bit
394 PowerPC, which probably could cause crashes on that platform
395 - fixed a memory management error which could cause a crash when a
396 plugin was unloaded
397 - bugfix: two private structs had the same name, which could cause
398 problems if the linker chose the wrong constructor
399 - fixed low-level ConditionServer usage bug that caused lockups on
400 Windows
401
402
403 Version 0.5.1 (6 December 2007)
404
405 * packaging changes:
406 - added autoconf checks for pthread library
407 - added autoconf check for pthread bug found on certain NPTL-enabled
408 glibc versions (see Gentoo bug report #194076)
409 - added autoconf checks for MS Windows
410
411 * general changes:
412 - bugfix: the thread used by an editor plugin didn't die when the
413 editor closed
414 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
415 out all the space. operator--() did not apply size_mask after
416 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
417 order to avoid problems with the _NonVolatileReader functions.
418 - bugfix: Stream.h: added a missing divide by BytesPerSample in
419 GetWriteSpace(). Since this function is currently only used in
420 the stream's qsort() compare function, it didn't trigger any
421 bugs.
422 - Resampler.h, Synthesizer.h: cubic interpolation now works in
423 24bit mode too. Faster method to read 24bit words on little
424 endian machines (x86): replaced 3 byte reads + shifts with a 1
425 unaligned 32bit read and shift
426 - experimental support for MS Windows (MIDI input via MME, AUDIO
427 output via ASIO)
428 - made handling of SIGINT signal (Ctrl-C) a bit more robust
429 - support for monitoring the total number of active disk streams
430 (new LSCP commands: GET TOTAL_STREAM_COUNT,
431 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
432
433 * AUDIO driver:
434 - added Windows ASIO low latency audio driver
435
436 * MIDI driver:
437 - added MME Windows MIDI driver
438
439 * LSCP server:
440 - added support for Windows style path / filenames, however with
441 forward slash path separators instead of backslash
442 (i.e. "C:/foo/bar.gig")
443 - allow naughty liblscp to send non-string device parameters within
444 apostrophes as well
445 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
446 "LIST FILE INSTRUMENTS <file>" and
447 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
448 about an arbitrary instrument file on the system where the sampler is
449 running on
450
451 Version 0.5.0 (15 October 2007)
452
453 * packaging changes:
454 - config.h is not going to be installed along with liblinuxsampler's
455 API header files anymore
456 - only the API relevant header (and source) files will be exported to
457 the Doxygen API documentation (explicitly listed in Doxyfile.in)
458 - added completely new XCode project files for Mac OSX which is now
459 capable to execute our autoconf environment, thus no need anymore
460 to maintain the compile time configuration file (osx/version.h) for
461 OSX manually (patch by Toshi Nagata)
462 - fixed buggy boolean --enable-foo / --disable-foo configure script
463 parameters
464 - global.h now only covers global definitions that are needed for the
465 C++ API header files, all implementation internal global definitions
466 are now in global_private.h
467 - atomic.h is not exposed to the C++ API anymore
468 - no need to include config.h anymore for using LS's API header files
469 - fixed warnings in API doc generation
470
471 * general changes:
472 - replaced the old, confusing MIDI program change mechanism by a
473 flexible MIDI instrument mapper which allows to map arbitrary
474 (MIDI bank, MIDI program) pairs with arbitrary
475 (engine type, instrument file, file index) triplets which will be
476 loaded on the respective channel when such MIDI program change
477 messages arrive, beside that, each entry allows to define a life-time
478 strategy for the instrument, so the user can define whether the
479 instrument should i.e. be permanently loaded (to be able to switch
480 quickly among sounds) or i.e. loaded just on demand when the
481 respective program change arrives (to safe RAM space), as well as a
482 global volume factor for each entry, so the user can adjust the volume
483 dynamic of his mapped instrument collection without having to modify
484 the instrument files, also one can manage arbitrary amount of such
485 MIDI instrument maps and assign each sampler channel individually
486 a certain map, so that i.e. separation of normal instruments and
487 drumkits is possible
488 - new notification events for tracking changes to audio/MIDI devices,
489 MIDI instrument maps, MIDI instruments, FX sends, global volume.
490 - sampler was limited to load max. 200 instruments in the background
491 due to a constant size RingBuffer FIFO which is now replaced by a
492 dynamic (unlimited) size std::list FIFO
493 - added FX sends, these allow to route audio signals to arbitrary audio
494 output channels for being processed by external effect processors
495 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
496 controllers
497 - global (sampler wide) volume can now be controlled at runtime
498 - Implemented new, improved notification system
499 - fixed compilation errors regarding OSX
500 (patch by Toshi Nagata)
501 - implemented instruments database
502 - added support for escape sequences to the instruments database
503 - added highly experimental support for on-the-fly instrument editing
504 within the sampler's process (by using instrument editor plugins),
505 you'll notice the new "Registered instrument editors:" message on
506 startup, added a new LSCP command:
507 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
508 to spawn a matching instrument editor for the instrument on the
509 given sampler channel, the plugin path can be overridden at compile
510 time with ./configure --enable-plugin-dir=/some/dir
511 - added experimental code for synchronizing instrument editors hosted
512 in the sampler's process to safely edit instruments while playing
513 without a crash (hopefully) by either suspending single regions
514 wherever possible or if unavoidable whole engine(s)
515 - fixed several issues in fundamental "Thread" class: set scheduling
516 policy and priority on thread level, set a minimum stack size for
517 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
518 threads simply inherited properties of starting thread instead of
519 setting their own policy and priority
520 - minor fix in our automatic stack trace mechanism on crashes, the
521 main process did not wait for the stack trace process to finish
522 its output
523 - fixed some minor memory leaks
524 - reenabled assembly features support, at the moment only for
525 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
526 - minor assembly fix in x86 features detection (don't use the PIC
527 register, to avoid relocations in the text segment at runtime)
528 - POSIX callback functions of Thread.h are hidden
529
530 * MIDI driver:
531 - dispatch bank select (MSB and LSB) messages
532
533 * audio driver:
534 - the ALSA audio output driver parameters now reflect the correct
535 parameter value ranges for the respective selected sound card
536 (patch by Till Wimmer, a bit fixed and extended)
537
538 * Gigasampler format engine:
539 - if a filter is used and EG2 finishes before EG1, let the voice
540 die when EG2 has finished (this fixes a problem with clicks and
541 voice starvation for some gigs)
542 - playback is no longer disabled during instrument loading
543 - all notes playing on a channel that changes its instrument keep
544 playing with the old instrument until they get a note off
545 command
546 - EG fix: a release value of zero could cause noises or crash
547 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
548 - EG fine tuning: when attack is zero the EG starts at a level
549 above max sustain level, which means that there is a decay phase
550 even if sustain is 100%
551 - more EG fixes: the level could sometimes go below zero and cause
552 noises or crashes
553 - minor fix of EGDecay (patch by Toshi Nagata)
554 - fixed compiler error when --enable-override-filter-type was
555 supplied to the configure script (fixes #46)
556 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
557 instead of a fix value
558 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
559 127 (solo mode) only kill voices if the respective mode really
560 changed
561
562 * LSCP server:
563 - fixed compile time error for old Bison versions
564 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
565 - parser now supports extended ASCII character set
566 (up to ASCII code 255, i.e. includes now umlauts and accents)
567 - filename arguments in LSCP commands now allow to use escape
568 sequences, that is directly literal as one of: \', \", \\, \n, \r,
569 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
570 code value like \xf2) (fixes bug #24)
571 - the following LSCP commands now also support escape sequences for at
572 least one of their text-based parameters (i.e. name, description):
573 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
574 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
575 "SET DB_INSTRUMENT_DIRECTORY NAME",
576 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
577 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
578 "FIND DB_INSTRUMENT_DIRECTORIES"
579 - returns verbose syntax errors (line and column where syntax error
580 occured, the unexpected character and the actually expected, possible
581 character(s), the latter only if less than 5 possibilities)
582 - made sure that LSCP syntax is not affected by gigedit locale
583 settings
584 - bugfix regarding strings parameter lists: all comma separated lists
585 of strings were treated as being one string containing commas
586 (fixes #57)
587
588 * Bug fixes:
589 - fixed crash occurring on certain LSCP scripts (Bug 39)
590 - another thread safety fix for lscp "load engine" and "set
591 channel audio output device"
592 - fixed a crash which occurs when reassigning the same engine
593 on a sampler channel with connected MIDI device
594 - fixed a crash which occurs when changing the number of ports of a MIDI
595 device connected to a sampler channel to number less then or equal
596 to the index of the port to which the sampler channel is connected.
597 - The previous bindings were not been disconnected when altering
598 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
599 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
600 - The active stream/voice count statistic was incorrect.
601 - notification events were not been sent for some sampler
602 channel changes
603 - added default min and max values to restrict the number of allowed
604 audio output channels and MIDI input ports
605 - the connection to the PCM interface is now closed when destroying
606 an audio output device
607 - files with slash in their path or filename could not be loaded
608
609 * test cases:
610 - updated and fixed (haven't been touched in a while)
611
612 Version 0.4.0 (24 November 2006)
613
614 * packaging changes:
615 - changed deprecated copyright attribute to license; added ldconfig
616 to post-(un)install steps; added devel package for liblinuxsampler;
617 to linuxsampler.spec (RPM)
618 - install necessary development header files for allowing 3rd party
619 applications to link against liblinuxsampler
620 - liblinuxsampler's API documentation can be generated with 'make docs'
621 (Doxygen required)
622 - added benchmark to automatically detect the best triangle LFO
623 implementation (currently either an integer math solution or a
624 di-harmonic approximation), automatic detection can be overriden
625 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
626 configure script argument though (mandatory for cross-compilation)
627 - do not automatically pick optimized gcc flags if the user already
628 provided some on his own (as CXXFLAGS)
629 - added compile time option to disable processing of All-Notes-Off MIDI
630 messages
631 - added compile time options to allow disabling the various audio and
632 MIDI drivers
633 - fixed automatic GCC CPU switch detection on PPC
634 (patch by Ebrahim Mayat)
635
636 * Gigasampler format engine:
637 - extensive synthesis optimization
638 (reimplementation of EGs and LFO(s), removed synthesis parameter
639 prerendering and the synthesis parameter matrix in general, splitting
640 each audio fragment into subfragments now where each subfragment uses
641 constant pitch and filter coefficients. The volume coefficient is
642 linearly interpolated inside a subfragment, unless
643 --disable-interpolate-volume is set.)
644 - fine tuning of the EG modulation parameters
645 - improved filter cutoff calculation by adding support for the
646 following gig parameters: Cutoff freq (used when no cutoff
647 controller is defined), Control invert, Minimum cutoff, Velocity
648 curve and Velocity range. The keyboard tracking now scales
649 cutoff frequency instead of resonance.
650 - added support for gig parameter Resonance.
651 - fixed bug in sysex handling (patch by Juan Linietsky)
652 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
653 which can be overridden with --enable-global-attenuation
654 - EG fixes: made the length of "attack hold" stage more
655 accurate. Release stage can now start before attack stage
656 ends. Cancel release didn't work when sustain was zero. Attack
657 time now has a minimal value to prevent clicks.
658 - fixed pitch changes larger than one octave
659 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
660 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
661 all modes can be altered via standard GM messages, that is CC5 for
662 altering portamento time, CC65 for enabling / disabling portamento
663 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
664 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
665 parameter) and crossfade
666 - added support for the "attenuation controller threshold" gig
667 parameter
668 - added smoothing of volume changes caused by control change
669 messages
670 - sample loop parameters are now taken from the DimensionRegion
671 instead of the wave chunk
672 - fixed keyswitching for v3 gigs with a number of keyswitch splits
673 not equal to a power of two
674 - reimplementation of the filter algorithm. The new filter is more
675 accurate and supports all gig filter types, including bandreject
676 and lowpass turbo.
677 - real support for 24 bit samples - samples are not truncated to
678 16 bits anymore
679 - support for aftertouch (channel pressure, not polyphonic
680 aftertouch)
681 - LFO1 behaviour fixed (dampening from max volume instead of
682 amplifying from 0)
683
684 * LSCP server:
685 - fixed application exit on broken pipe error (fixes bug #20)
686 - fixed the notification messages delay due to lack of
687 network activity (fixes bug #26)
688 - fixed parser bug which occured on space(s) within device parameters
689 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
690
691 * audio driver:
692 - added aRts audio output driver (by no means RT safe)
693
694 * MIDI driver:
695 - fixed legacy sysex code which caused dispatching of MIDI SysEx
696 messages several times instead of once
697 - API extension for MIDI drivers which already supply exact time stamps
698 for events (i.e. for offline rendering based MIDI drivers)
699 - added checks for bad MIDI data
700
701 * linuxsampler application:
702 - show available sampler engine types on startup
703
704 * general changes:
705 - support for muting sampler channels and solo mode of the same, two new
706 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
707 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
708 introduced for this, the behavior is the same like on a mixer console
709 (patch by Grigor Iliev, a bit adjusted). Also added configure option
710 --enable-process-muted-channels which can be used to enable the
711 processing of muted channels.
712 - support for sostenuto pedal
713 - support for monitoring the total number of active voices
714 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
715 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
716 - fixed some memory management errors
717 - fixed some concurrency problems that could lead to crashes when
718 LSCP commands were executed
719 - fixed crash when instrument loading failed previously on the same
720 sampler channel (fixes bug #36)
721
722 Version 0.3.3 (15 July 2005)
723
724 * packaging changes:
725 - fixed compilation with gcc 4.0
726
727 * Gigasampler format engine:
728 - LFO preprocessing was performed even though the respective LFO was
729 disabled by the instrument patch (minor efficiency fix)
730 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
731 for volume ramp downs in the same fragment (needed for current voice
732 stealing implementation) then simply inform the user with a warning
733 about possible click sounds and reduce the volume ramp down
734 appropriately instead of cancelling the audio device connection
735
736 Version 0.3.2 (24 June 2005)
737
738 * packaging changes:
739 - updated autotools build files to compile on OS X
740 (conditional compilation of CoreMIDI and MidiShare drivers)
741 - hand-crafted assembly optimization code can be disabled with
742 './configure --disable-asm' (definitely not recommended)
743 - fixed 'make dist' rule to include all necessary files
744 - require automake (>= 1.5) for 'make -f Makefile.cvs'
745 (due to 'dist-bzip2' automake option)
746
747 * Gigasampler format engine:
748 - support for the gig parameters for "release velocity response" curves
749 - fine tuning of the EGADSR envelope
750 - volume of release triggered samples now depends on note-on velocity,
751 note length and gig parameter "release trigger decay" instead of
752 note-off velocity.
753 - revised voice stealing
754 (fixes crash and endless loop caused by voice stealing)
755 - don't reset scale tuning on instrument or audio output device change
756 - handle key group conflicts right at the beginning of each fragment
757 instead of when the respective voice is actually launched
758 (fixes undefined behavior if stolen voices belonged to a key group -
759 this case was followed by a "killed voice survived" error message)
760 - fixed minor issue with null/silence samples
761 (those stole voices even though they don't need a voice at all which
762 resulted in "voice stealing didn't work out" messages)
763 - don't reset volume, pan, pitch and MIDI controller values on
764 instrument or audio output device change
765
766 * LSCP server:
767 - fixed some crashes (patch by Grigor Iliev, fixes #19)
768 - fixed LSCP event "CHANNEL_INFO" notification
769 (e.g. did not notify on volume changes or MIDI program change events)
770
771 * linuxsampler application:
772 - added command line parameters --lscp-addr and --lscp-port to override
773 default IP address and port of LSCP server
774
775 Version 0.3.1 (24 May 2005)
776
777 * initial release
