* Fixed possible crashes due to corrupted MIDI/audio device list
  after MIDI/audio device creation failure

1 Version CVS HEAD (?)
3 * plugin changes:
4 - LV2 Persist + Files support (patch by David Robillard)
6 * packaging changes:
7 - fixed building with newer MinGW-w64
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 - minor Makefile fix for building lscpparser when build and source
17 directories are separate
19 * general changes:
20 - Refactoring: moved the independent code from
21 the Gigasampler format engine to base classes
22 - command line option '--profile' is currently disabled, since the
23 respective profiling code is currently broken
24 - Introduced support for optional environment variable
25 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
26 where the sampler shall look for instrument editor plugins
27 (patch by Luis Garrido, slightly modified).
28 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
29 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
30 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
31 note (in this implementation of the sampler its simply hard routed to
32 the 1st effect send of the sampler channel, no matter what the actual
33 effect type is)
34 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
35 note (in this implementation of the sampler its simply hard routed to
36 the 2nd effect send of the sampler channel, no matter what the actual
37 effect type is)
38 - implemented support for internal LADSPA effects
39 - raised limit of program change queue from 100 to 512
40 (as suggested by Alex Stone)
42 * Gigasampler format engine:
43 - implemented the "round robin keyboard" dimension
44 - fixed round robin and random dimensions for cases when number of
45 dimension zones is not a power of two
46 - made round robin use a counter for each region instead of each
47 key
49 * SFZ format engine:
50 - Initial implementation (not usable yet)
51 - added support for v2 multiple stage envelope generators

55 - added support for trigger=first, trigger=legato and sw_previous
56 - allow non-numerical key values ("C#4" for example)
57 - "key" opcode now sets pitch_keycenter too
58 - fixed error when unloading instrument with same sample used by

83 not set in sfz file
84 - implemeted filters. Filter types: lowpass, bandpass, bandreject
85 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
86 cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
87 cutoff_cc, cutoff_chanaft.
88 - bugfix: zero ampeg_sustain didn't work
89 - added support for velocity effect on amplifier envelope time
90 (ampeg_vel2attack, ampeg_vel2decay, ampeg_vel2sustain and
91 ampeg_vel2release)
93 * SoundFont format engine:
94 - Initial implementation (not usable yet)
95 - RT-safeness: avoid malloc in audio thread

104 * Host plugins:
105 - AU bugfix: failed to destroy its audio/MIDI devices
106 - Listen to all interfaces on Mac OS X (INADDR_ANY)
107 - VST bugfix: If the host called resume() before and after
108 changing sample rate or block size, the number of channels was
109 incorrectly set to two. This caused silence in Cubase 5.
110 - save engine type (gig, sfz or sf2) in plugin state
111 - VST: when opening Fantasia, look for both 32 and 64 bit Java on
112 64 bit Windows

117 specified
119 * MIDI driver:
120 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
121 the ALSA sequencer client name
122 - removed limit of maximum amount of MIDI ports per MIDI device, since
123 there is no reason for this limit
125 * audio driver:
126 - ASIO driver fixes for newer gcc versions (fix from PortAudio)

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