* Mac OS X: fixed hanging threads

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