File size: 39475 byte(s)
* Windows: disabled the previous thread fix on non-Mac systems, as it
  caused hanging threads on Windows

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

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

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

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
106 changing sample rate or block size, the number of channels was
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

154
155 * Bug fixes:
156 - Fixed crash which may occur when MIDI key + transpose is out of range
157 - minor valgrind fixes
158 - fixed crash which occured when changing an already deployed sampler
159 channel to a different engine type
160 - fixed crash when deleting a sampler channel or changing engine
161 type while an instrument load was in progress
162 - bugfix: playing a note while changing the instrument could cause
163 a crash, or give "Handing back unknown region" error messages
164 - bugfix: calling SET VOICES (which Fantasia does on start and
165 refresh) could cause instruments to be unloaded
166 - Mac OS X: fixed name collision of enum in EffectControl and
167 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
168 - Mac OS X: fixed hanging threads
169 - Windows: disabled the previous thread fix on non-Mac systems, as
170 it caused hanging threads on Windows
171
172 Version 1.0.0 (31 July 2009)
173
174 * packaging changes:
175 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
176 causing e.g. the libgig test to fail when
177 "./configure --disable-jack-driver" was used
178 (patch by Alexis Ballier)
179 - fixed compilation with gcc 4.3
180 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
181 - fixed configure so it detects x86_64 (#107)
182 - fixes for building with newer MinGW versions
183 - fix for building with bison 2.4 (#111)
184 - fixed building with libgig installed in a non-standard directory
185 - minor fix in configure for mmsystem.h detection on MinGW
186 - Windows: look for editor plugins and Fantasia using base
187 directory of liblinuxsampler dll (look in the same directory and one
188 directory above)
189 - configure script fix: removed unconditional use of SSE
190 - fixed building with sqlite installed in a non-standard directory
191 - when cross-compiling, don't try to create instruments.db
192 - fix for new mingw-w64 version, which has usleep
193
194 * general changes:
195 - bugfix: on some POSIX systems instrument editor plugins refused to
196 load as we used a non-portable Linux specific struct field
197 (fixes bug #70, patch by Ronald Baljeu)
198 - fixed endless loop which occured when loading an instrument editor
199 plugin DLL on Windows systems failed
200 - fixed memory leaks that occurred when liblinuxsampler was unloaded
201 - optimized the SynchronizedConfig class so it doesn't wait
202 unnecessarily long after an update
203 - added support for notifying instrument editors on note-on / note-off
204 events (e.g. to highlight the pressed keys on the virtual keyboard
205 of gigedit)
206 - added support for triggering notes by instrument editors (see above)
207 - be verbose on DLL load errors (on Linux)
208 - fixed di-harmonic triangle LFO implementation (this LFO implementation
209 is only used by very few systems, most pick the int math
210 implementation, which is usually faster)
211 - fixes for audio drivers with varying buffer sizes
212 - experimental support for running LinuxSampler as a DSSI, LV2 and
213 VST plugin
214 - notification events for stream/voice count statistics are now sent
215 only when there are actual changes
216 - added memory ordering constraints to improve stability on
217 multi-core and multi-cpu systems
218 - maximum voices and disk streams can now be altered at runtime
219 - fixed CPU feature detection on x86_64 (maybe fixes #108)
220 - automatic stacktrace mechanism is now turned off by default and can
221 be switched on by command line option "--stacktrace" (the automatic
222 stacktrace mechanism seems to be broken on most systems at the moment)
223 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
224 a pointer to the launched InstrumentEditor object
225 - added optional 3rd party user data parameter for following
226 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
227 InstrumentEditor::Launch(),
228 InstrumentManager::LaunchInstrumentEditor()
229 - theoretical fix: made SynchronizedConfig follow C++0x memory
230 model more strictly
231 - fixes for using large audio device buffers
232 - Windows: add the installation directory to the DLL search path
233 when loading an editor plugin (solves problems with VST and
234 gigedit on systems with other GTK versions installed)
235
236 * audio driver:
237 - removed the nonsense audio channel constraint (which was hard coded to
238 max. 100 audio channels) for most audio drivers
239 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
240 opposed to the LSCP specs
241 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
242 reflected the wrong value
243 - fixed a memory management bug in ASIO driver
244 - Makefile fix: JACK_CFLAGS wasn't used
245 - JACK: use jack_client_open instead of the deprecated
246 jack_client_new
247 - added (experimental) CoreAudio driver
248 - applied old fixes to the ASIO driver that were included in the
249 previous binary release but accidentally never committed to CVS
250 (fixes #117)
251 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
252 win64)
253 - VST: added support for sample rate and buffer size changes
254 - VST: close editor (Fantasia) when the VST is removed
255 - VST: avoid opening Fantasia more than once for each VST instance
256 - VST: export main function as "main" on Linux too (fix for
257 energyXT)
258 - VST: changed number of output channels from one stereo to 16
259 stereo
260 - added channel routing, fxsends and midi maps to the settings
261 stored in the plugin state
262 - performance optimization of AudioChannel::MixTo() and
263 AudioChannel::CopyTo() methods using GCC vector exensions
264 (if available)
265 - ASIO fixes: avoid initializing the device twice, avoid throwing
266 exception when getting parameters from a disconnected device
267
268 * MIDI driver:
269 - added JACK MIDI driver
270 - dispatch bank select as ordinary CC as well, the user might seriously
271 want to (mis)use it for some purpose ("fixed" in all current MIDI
272 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
273 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
274 CoreMidi or AU
275 - fixed mingw-w64 compilation error in MME driver
276 - made program change handling in MIDI thread real-time safe by
277 moving the logic to a non-RT thread
278 - fixed minor memory leak in ALSA driver
279
280 * instruments database:
281 - avoid time consuming samples scanning when adding instruments
282 to the instruments database
283 - added support for handling lost files in the instruments database
284 - Implemented option for adding instruments in separate directories
285 in the instruments database
286 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
287 - work-around for missing fnmatch function on Windows to make
288 instrument database compilable
289 - added instrument database support on Windows
290 works with both standalone mode and VST plugin.
291 the instruments DB file is located in
292 %USERPROFILE%\.linuxsampler\instruments.db which allows different
293 databases for each windows user
294 if no DB is present it automatically creates the .linuxsampler subdir
295 and then creates an empty DB
296 - fixed recursive import, which was broken on Windows
297
298 * Gigasampler format engine:
299 - fixed a memory leak that could happen when a channel was deleted
300 while notes were playing
301 - made it possible to load an instrument even if the audio thread
302 isn't running
303 - added partial support for the "Controller Triggered" MIDI rule,
304 enough for piano gigs with pedal noise samples
305 - minor fix: only mark FX sends as being modified if really the
306 respective FX send MIDI controller was used
307 - added support for GM global device volume SysEx message
308 (can be selected at compile time to either apply globally to the
309 whole sampler [default] or only to the sampler channels that are
310 connected to the respective MIDI input port the SysEx message arrived
311 on)
312 - bugfix: notes triggered at position 0 in the audio buffer were
313 sometimes wrongly killed in the same buffer, causing no sound to
314 be played
315 - added support for chromatic / drumkit mode Roland GS Sysex message
316 which is usally used to switch a part between chromatic sounds and
317 drumkit sounds (as opposed to their common default setting of MIDI
318 part 10 being a drumkit part and all other ones chromatic parts), in
319 LS however one can switch between the first 16 MIDI instrument maps
320 defined for the sampler
321 - made it possible to create multiple sample channels even if the
322 audio thread isn't running
323 - fixed crash when removing channel with active voices (#116)
324 - bugfix: on sample reference changes (instrument editor), only
325 un-cache the respective sample if it's really not used by any
326 sampler engine anymore
327 - re-cache samples in case they were changed by an instrument editor,
328 e.g. when a sample was added while playing (#82)
329 - fixed hanging notes which occured when note-off event had the exact
330 same time stamp as the voice's note-on event and occured both in the
331 same audio fragment cycle (fixes bug #112)
332 - added support for the "fine tune" and "pitch bend range"
333 instrument-level gig parameters
334 - fixed minor artifacts in pitch bend handling
335 - added support for GS Reset SysEx message
336 - allow gig files to use unlimited downward pitch shifting
337 - added a limit check for upward pitch shifting
338 - bugfix: sometimes, when playing a note twice fast, the second
339 note was silent
340 - fixed crash happening when a pitch bend event arrived at the
341 same time a new instrument was loading
342
343 * LSCP server:
344 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
345 react on MIDI data arriving on certain sampler channels (so far only
346 Note-On and Note-Off events are sent via this LSCP event)
347 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
348 react on MIDI data arriving on certain MIDI input devices (so far only
349 Note-On and Note-Off events are sent via this LSCP event)
350 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
351 SET DB_INSTRUMENT FILE_PATH
352 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
353 frontends to send MIDI messages to specific sampler channel
354 - added two additional fields to GET FILE INSTRUMENT INFO command -
355 KEY_BINDINGS and KEYSWITCH_BINDINGS
356 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
357 was incorrect
358 - Optimized the retrieval of the MIDI instrument mappings
359 - added new LSCP command "SET VOICES" to globally alter the maximum
360 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
361 be triggered respectively
362 - added new LSCP command "SET STREAMS" to globally alter the maximum
363 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
364 which will be triggered respectively
365 - bugfix: retry if "select" returns EINTR (this fixes a crash when
366 a gigedit file dialog is opened)
367 - close all connections when LSCPServer is deleted
368 - hard close of all sockets on exit
369 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
370 driver
371
372 * Bug fixes:
373 - fixed a crash which occurs when removing a sampler channel waiting
374 to start instrument loading after another channel
375 - fixed a crash which occurs when removing a sampler channel with
376 instrument loading in progress (bug #113)
377 - fixed termination caused by uncaught exception when adding MIDI
378 instrument with PERSISTENT load mode
379 - fixed possible iterator invalidations when resetting the sampler
380 - fixed memory leaks when issuing the following LSCP commands:
381 GET AUDIO_OUTPUT_DRIVER INFO
382 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
383 GET MIDI_INPUT_DRIVER INFO
384 GET MIDI_INPUT_DRIVER_PARAMETER INFO
385 - fixed possible compilation error when sqlite is not present
386 - fixed orphaned pointers when setting maximum voices limit (bug #118)
387 - fixed crash when changing the audio output device of a sampler
388 channel with loaded instrument and start playing notes
389 - fixed endless loop in Engine::SuspendAll() (bug #120)
390 - fixed a low-level atomic load function that was broken on 64-bit
391 PowerPC, which probably could cause crashes on that platform
392 - fixed a memory management error which could cause a crash when a
393 plugin was unloaded
394 - bugfix: two private structs had the same name, which could cause
395 problems if the linker chose the wrong constructor
396 - fixed low-level ConditionServer usage bug that caused lockups on
397 Windows
398
399
400 Version 0.5.1 (6 December 2007)
401
402 * packaging changes:
403 - added autoconf checks for pthread library
404 - added autoconf check for pthread bug found on certain NPTL-enabled
405 glibc versions (see Gentoo bug report #194076)
406 - added autoconf checks for MS Windows
407
408 * general changes:
409 - bugfix: the thread used by an editor plugin didn't die when the
410 editor closed
411 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
412 out all the space. operator--() did not apply size_mask after
413 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
414 order to avoid problems with the _NonVolatileReader functions.
415 - bugfix: Stream.h: added a missing divide by BytesPerSample in
416 GetWriteSpace(). Since this function is currently only used in
417 the stream's qsort() compare function, it didn't trigger any
418 bugs.
419 - Resampler.h, Synthesizer.h: cubic interpolation now works in
420 24bit mode too. Faster method to read 24bit words on little
421 endian machines (x86): replaced 3 byte reads + shifts with a 1
422 unaligned 32bit read and shift
423 - experimental support for MS Windows (MIDI input via MME, AUDIO
424 output via ASIO)
425 - made handling of SIGINT signal (Ctrl-C) a bit more robust
426 - support for monitoring the total number of active disk streams
427 (new LSCP commands: GET TOTAL_STREAM_COUNT,
428 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
429
430 * AUDIO driver:
431 - added Windows ASIO low latency audio driver
432
433 * MIDI driver:
434 - added MME Windows MIDI driver
435
436 * LSCP server:
437 - added support for Windows style path / filenames, however with
438 forward slash path separators instead of backslash
439 (i.e. "C:/foo/bar.gig")
440 - allow naughty liblscp to send non-string device parameters within
441 apostrophes as well
442 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
443 "LIST FILE INSTRUMENTS <file>" and
444 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
445 about an arbitrary instrument file on the system where the sampler is
446 running on
447
448 Version 0.5.0 (15 October 2007)
449
450 * packaging changes:
451 - config.h is not going to be installed along with liblinuxsampler's
452 API header files anymore
453 - only the API relevant header (and source) files will be exported to
454 the Doxygen API documentation (explicitly listed in Doxyfile.in)
455 - added completely new XCode project files for Mac OSX which is now
456 capable to execute our autoconf environment, thus no need anymore
457 to maintain the compile time configuration file (osx/version.h) for
458 OSX manually (patch by Toshi Nagata)
459 - fixed buggy boolean --enable-foo / --disable-foo configure script
460 parameters
461 - global.h now only covers global definitions that are needed for the
462 C++ API header files, all implementation internal global definitions
463 are now in global_private.h
464 - atomic.h is not exposed to the C++ API anymore
465 - no need to include config.h anymore for using LS's API header files
466 - fixed warnings in API doc generation
467
468 * general changes:
469 - replaced the old, confusing MIDI program change mechanism by a
470 flexible MIDI instrument mapper which allows to map arbitrary
471 (MIDI bank, MIDI program) pairs with arbitrary
472 (engine type, instrument file, file index) triplets which will be
473 loaded on the respective channel when such MIDI program change
474 messages arrive, beside that, each entry allows to define a life-time
475 strategy for the instrument, so the user can define whether the
476 instrument should i.e. be permanently loaded (to be able to switch
477 quickly among sounds) or i.e. loaded just on demand when the
478 respective program change arrives (to safe RAM space), as well as a
479 global volume factor for each entry, so the user can adjust the volume
480 dynamic of his mapped instrument collection without having to modify
481 the instrument files, also one can manage arbitrary amount of such
482 MIDI instrument maps and assign each sampler channel individually
483 a certain map, so that i.e. separation of normal instruments and
484 drumkits is possible
485 - new notification events for tracking changes to audio/MIDI devices,
486 MIDI instrument maps, MIDI instruments, FX sends, global volume.
487 - sampler was limited to load max. 200 instruments in the background
488 due to a constant size RingBuffer FIFO which is now replaced by a
489 dynamic (unlimited) size std::list FIFO
490 - added FX sends, these allow to route audio signals to arbitrary audio
491 output channels for being processed by external effect processors
492 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
493 controllers
494 - global (sampler wide) volume can now be controlled at runtime
495 - Implemented new, improved notification system
496 - fixed compilation errors regarding OSX
497 (patch by Toshi Nagata)
498 - implemented instruments database
499 - added support for escape sequences to the instruments database
500 - added highly experimental support for on-the-fly instrument editing
501 within the sampler's process (by using instrument editor plugins),
502 you'll notice the new "Registered instrument editors:" message on
503 startup, added a new LSCP command:
504 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
505 to spawn a matching instrument editor for the instrument on the
506 given sampler channel, the plugin path can be overridden at compile
507 time with ./configure --enable-plugin-dir=/some/dir
508 - added experimental code for synchronizing instrument editors hosted
509 in the sampler's process to safely edit instruments while playing
510 without a crash (hopefully) by either suspending single regions
511 wherever possible or if unavoidable whole engine(s)
512 - fixed several issues in fundamental "Thread" class: set scheduling
513 policy and priority on thread level, set a minimum stack size for
514 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
515 threads simply inherited properties of starting thread instead of
516 setting their own policy and priority
517 - minor fix in our automatic stack trace mechanism on crashes, the
518 main process did not wait for the stack trace process to finish
519 its output
520 - fixed some minor memory leaks
521 - reenabled assembly features support, at the moment only for
522 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
523 - minor assembly fix in x86 features detection (don't use the PIC
524 register, to avoid relocations in the text segment at runtime)
525 - POSIX callback functions of Thread.h are hidden
526
527 * MIDI driver:
528 - dispatch bank select (MSB and LSB) messages
529
530 * audio driver:
531 - the ALSA audio output driver parameters now reflect the correct
532 parameter value ranges for the respective selected sound card
533 (patch by Till Wimmer, a bit fixed and extended)
534
535 * Gigasampler format engine:
536 - if a filter is used and EG2 finishes before EG1, let the voice
537 die when EG2 has finished (this fixes a problem with clicks and
538 voice starvation for some gigs)
539 - playback is no longer disabled during instrument loading
540 - all notes playing on a channel that changes its instrument keep
541 playing with the old instrument until they get a note off
542 command
543 - EG fix: a release value of zero could cause noises or crash
544 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
545 - EG fine tuning: when attack is zero the EG starts at a level
546 above max sustain level, which means that there is a decay phase
547 even if sustain is 100%
548 - more EG fixes: the level could sometimes go below zero and cause
549 noises or crashes
550 - minor fix of EGDecay (patch by Toshi Nagata)
551 - fixed compiler error when --enable-override-filter-type was
552 supplied to the configure script (fixes #46)
553 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
554 instead of a fix value
555 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
556 127 (solo mode) only kill voices if the respective mode really
557 changed
558
559 * LSCP server:
560 - fixed compile time error for old Bison versions
561 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
562 - parser now supports extended ASCII character set
563 (up to ASCII code 255, i.e. includes now umlauts and accents)
564 - filename arguments in LSCP commands now allow to use escape
565 sequences, that is directly literal as one of: \', \", \\, \n, \r,
566 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
567 code value like \xf2) (fixes bug #24)
568 - the following LSCP commands now also support escape sequences for at
569 least one of their text-based parameters (i.e. name, description):
570 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
571 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
572 "SET DB_INSTRUMENT_DIRECTORY NAME",
573 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
574 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
575 "FIND DB_INSTRUMENT_DIRECTORIES"
576 - returns verbose syntax errors (line and column where syntax error
577 occured, the unexpected character and the actually expected, possible
578 character(s), the latter only if less than 5 possibilities)
579 - made sure that LSCP syntax is not affected by gigedit locale
580 settings
581 - bugfix regarding strings parameter lists: all comma separated lists
582 of strings were treated as being one string containing commas
583 (fixes #57)
584
585 * Bug fixes:
586 - fixed crash occurring on certain LSCP scripts (Bug 39)
587 - another thread safety fix for lscp "load engine" and "set
588 channel audio output device"
589 - fixed a crash which occurs when reassigning the same engine
590 on a sampler channel with connected MIDI device
591 - fixed a crash which occurs when changing the number of ports of a MIDI
592 device connected to a sampler channel to number less then or equal
593 to the index of the port to which the sampler channel is connected.
594 - The previous bindings were not been disconnected when altering
595 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
596 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
597 - The active stream/voice count statistic was incorrect.
598 - notification events were not been sent for some sampler
599 channel changes
600 - added default min and max values to restrict the number of allowed
601 audio output channels and MIDI input ports
602 - the connection to the PCM interface is now closed when destroying
603 an audio output device
604 - files with slash in their path or filename could not be loaded
605
606 * test cases:
607 - updated and fixed (haven't been touched in a while)
608
609 Version 0.4.0 (24 November 2006)
610
611 * packaging changes:
612 - changed deprecated copyright attribute to license; added ldconfig
613 to post-(un)install steps; added devel package for liblinuxsampler;
614 to linuxsampler.spec (RPM)
615 - install necessary development header files for allowing 3rd party
616 applications to link against liblinuxsampler
617 - liblinuxsampler's API documentation can be generated with 'make docs'
618 (Doxygen required)
619 - added benchmark to automatically detect the best triangle LFO
620 implementation (currently either an integer math solution or a
621 di-harmonic approximation), automatic detection can be overriden
622 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
623 configure script argument though (mandatory for cross-compilation)
624 - do not automatically pick optimized gcc flags if the user already
625 provided some on his own (as CXXFLAGS)
626 - added compile time option to disable processing of All-Notes-Off MIDI
627 messages
628 - added compile time options to allow disabling the various audio and
629 MIDI drivers
630 - fixed automatic GCC CPU switch detection on PPC
631 (patch by Ebrahim Mayat)
632
633 * Gigasampler format engine:
634 - extensive synthesis optimization
635 (reimplementation of EGs and LFO(s), removed synthesis parameter
636 prerendering and the synthesis parameter matrix in general, splitting
637 each audio fragment into subfragments now where each subfragment uses
638 constant pitch and filter coefficients. The volume coefficient is
639 linearly interpolated inside a subfragment, unless
640 --disable-interpolate-volume is set.)
641 - fine tuning of the EG modulation parameters
642 - improved filter cutoff calculation by adding support for the
643 following gig parameters: Cutoff freq (used when no cutoff
644 controller is defined), Control invert, Minimum cutoff, Velocity
645 curve and Velocity range. The keyboard tracking now scales
646 cutoff frequency instead of resonance.
647 - added support for gig parameter Resonance.
648 - fixed bug in sysex handling (patch by Juan Linietsky)
649 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
650 which can be overridden with --enable-global-attenuation
651 - EG fixes: made the length of "attack hold" stage more
652 accurate. Release stage can now start before attack stage
653 ends. Cancel release didn't work when sustain was zero. Attack
654 time now has a minimal value to prevent clicks.
655 - fixed pitch changes larger than one octave
656 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
657 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
658 all modes can be altered via standard GM messages, that is CC5 for
659 altering portamento time, CC65 for enabling / disabling portamento
660 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
661 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
662 parameter) and crossfade
663 - added support for the "attenuation controller threshold" gig
664 parameter
665 - added smoothing of volume changes caused by control change
666 messages
667 - sample loop parameters are now taken from the DimensionRegion
668 instead of the wave chunk
669 - fixed keyswitching for v3 gigs with a number of keyswitch splits
670 not equal to a power of two
671 - reimplementation of the filter algorithm. The new filter is more
672 accurate and supports all gig filter types, including bandreject
673 and lowpass turbo.
674 - real support for 24 bit samples - samples are not truncated to
675 16 bits anymore
676 - support for aftertouch (channel pressure, not polyphonic
677 aftertouch)
678 - LFO1 behaviour fixed (dampening from max volume instead of
679 amplifying from 0)
680
681 * LSCP server:
682 - fixed application exit on broken pipe error (fixes bug #20)
683 - fixed the notification messages delay due to lack of
684 network activity (fixes bug #26)
685 - fixed parser bug which occured on space(s) within device parameters
686 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
687
688 * audio driver:
689 - added aRts audio output driver (by no means RT safe)
690
691 * MIDI driver:
692 - fixed legacy sysex code which caused dispatching of MIDI SysEx
693 messages several times instead of once
694 - API extension for MIDI drivers which already supply exact time stamps
695 for events (i.e. for offline rendering based MIDI drivers)
696 - added checks for bad MIDI data
697
698 * linuxsampler application:
699 - show available sampler engine types on startup
700
701 * general changes:
702 - support for muting sampler channels and solo mode of the same, two new
703 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
704 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
705 introduced for this, the behavior is the same like on a mixer console
706 (patch by Grigor Iliev, a bit adjusted). Also added configure option
707 --enable-process-muted-channels which can be used to enable the
708 processing of muted channels.
709 - support for sostenuto pedal
710 - support for monitoring the total number of active voices
711 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
712 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
713 - fixed some memory management errors
714 - fixed some concurrency problems that could lead to crashes when
715 LSCP commands were executed
716 - fixed crash when instrument loading failed previously on the same
717 sampler channel (fixes bug #36)
718
719 Version 0.3.3 (15 July 2005)
720
721 * packaging changes:
722 - fixed compilation with gcc 4.0
723
724 * Gigasampler format engine:
725 - LFO preprocessing was performed even though the respective LFO was
726 disabled by the instrument patch (minor efficiency fix)
727 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
728 for volume ramp downs in the same fragment (needed for current voice
729 stealing implementation) then simply inform the user with a warning
730 about possible click sounds and reduce the volume ramp down
731 appropriately instead of cancelling the audio device connection
732
733 Version 0.3.2 (24 June 2005)
734
735 * packaging changes:
736 - updated autotools build files to compile on OS X
737 (conditional compilation of CoreMIDI and MidiShare drivers)
738 - hand-crafted assembly optimization code can be disabled with
739 './configure --disable-asm' (definitely not recommended)
740 - fixed 'make dist' rule to include all necessary files
741 - require automake (>= 1.5) for 'make -f Makefile.cvs'
742 (due to 'dist-bzip2' automake option)
743
744 * Gigasampler format engine:
745 - support for the gig parameters for "release velocity response" curves
746 - fine tuning of the EGADSR envelope
747 - volume of release triggered samples now depends on note-on velocity,
748 note length and gig parameter "release trigger decay" instead of
749 note-off velocity.
750 - revised voice stealing
751 (fixes crash and endless loop caused by voice stealing)
752 - don't reset scale tuning on instrument or audio output device change
753 - handle key group conflicts right at the beginning of each fragment
754 instead of when the respective voice is actually launched
755 (fixes undefined behavior if stolen voices belonged to a key group -
756 this case was followed by a "killed voice survived" error message)
757 - fixed minor issue with null/silence samples
758 (those stole voices even though they don't need a voice at all which
759 resulted in "voice stealing didn't work out" messages)
760 - don't reset volume, pan, pitch and MIDI controller values on
761 instrument or audio output device change
762
763 * LSCP server:
764 - fixed some crashes (patch by Grigor Iliev, fixes #19)
765 - fixed LSCP event "CHANNEL_INFO" notification
766 (e.g. did not notify on volume changes or MIDI program change events)
767
768 * linuxsampler application:
769 - added command line parameters --lscp-addr and --lscp-port to override
770 default IP address and port of LSCP server
771
772 Version 0.3.1 (24 May 2005)
773
774 * initial release
