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 the 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
18 - Mac OS X: made it possible to specify plugin installation dir to
19 configure
20 - Mac OS X: Makefile fix for the install-strip target
21
22 * general changes:
23 - Refactoring: moved the independent code from
24 the Gigasampler format engine to base classes
25 - command line option '--profile' is currently disabled, since the
26 respective profiling code is currently broken
27 - Introduced support for optional environment variable
28 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
29 where the sampler shall look for instrument editor plugins
30 (patch by Luis Garrido, slightly modified).
31 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
32 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
33 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
34 note (in this implementation of the sampler its simply hard routed to
35 the 1st effect send of the sampler channel, no matter what the actual
36 effect type is)
37 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
38 note (in this implementation of the sampler its simply hard routed to
39 the 2nd effect send of the sampler channel, no matter what the actual
40 effect type is)
41 - implemented support for internal LADSPA effects
42 - raised limit of program change queue from 100 to 512
43 (as suggested by Alex Stone)
44

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

180
181 * Bug fixes:
182 - Fixed crash which may occur when MIDI key + transpose is out of range
183 - minor valgrind fixes
184 - fixed crash which occurred when changing an already deployed sampler
185 channel to a different engine type
186 - fixed crash when deleting a sampler channel or changing engine
187 type while an instrument load was in progress
188 - bugfix: playing a note while changing the instrument could cause
189 a crash, or give "Handing back unknown region" error messages
190 - bugfix: calling SET VOICES (which Fantasia does on start and
191 refresh) could cause instruments to be unloaded
192 - Mac OS X: fixed name collision of enum in EffectControl and

198 after MIDI/audio device creation failure
199
200 Version 1.0.0 (31 July 2009)
201
202 * packaging changes:
203 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
204 causing e.g. the libgig test to fail when
205 "./configure --disable-jack-driver" was used
206 (patch by Alexis Ballier)
207 - fixed compilation with gcc 4.3
208 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
209 - fixed configure so it detects x86_64 (#107)
210 - fixes for building with newer MinGW versions
211 - fix for building with bison 2.4 (#111)
212 - fixed building with libgig installed in a non-standard directory
213 - minor fix in configure for mmsystem.h detection on MinGW
214 - Windows: look for editor plugins and Fantasia using base
215 directory of liblinuxsampler dll (look in the same directory and one
216 directory above)
217 - configure script fix: removed unconditional use of SSE
218 - fixed building with sqlite installed in a non-standard directory
219 - when cross-compiling, don't try to create instruments.db
220 - fix for new mingw-w64 version, which has usleep
221
222 * general changes:
223 - bugfix: on some POSIX systems instrument editor plugins refused to
224 load as we used a non-portable Linux specific struct field
225 (fixes bug #70, patch by Ronald Baljeu)
226 - fixed endless loop which occured when loading an instrument editor
227 plugin DLL on Windows systems failed
228 - fixed memory leaks that occurred when liblinuxsampler was unloaded
229 - optimized the SynchronizedConfig class so it doesn't wait
230 unnecessarily long after an update
231 - added support for notifying instrument editors on note-on / note-off
232 events (e.g. to highlight the pressed keys on the virtual keyboard
233 of gigedit)
234 - added support for triggering notes by instrument editors (see above)
235 - be verbose on DLL load errors (on Linux)
236 - fixed di-harmonic triangle LFO implementation (this LFO implementation
237 is only used by very few systems, most pick the int math
238 implementation, which is usually faster)
239 - fixes for audio drivers with varying buffer sizes
240 - experimental support for running LinuxSampler as a DSSI, LV2 and
241 VST plugin
242 - notification events for stream/voice count statistics are now sent
243 only when there are actual changes
244 - added memory ordering constraints to improve stability on
245 multi-core and multi-cpu systems
246 - maximum voices and disk streams can now be altered at runtime
247 - fixed CPU feature detection on x86_64 (maybe fixes #108)
248 - automatic stacktrace mechanism is now turned off by default and can
249 be switched on by command line option "--stacktrace" (the automatic
250 stacktrace mechanism seems to be broken on most systems at the moment)
251 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
252 a pointer to the launched InstrumentEditor object
253 - added optional 3rd party user data parameter for following
254 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
255 InstrumentEditor::Launch(),
256 InstrumentManager::LaunchInstrumentEditor()
257 - theoretical fix: made SynchronizedConfig follow C++0x memory
258 model more strictly
259 - fixes for using large audio device buffers
260 - Windows: add the installation directory to the DLL search path
261 when loading an editor plugin (solves problems with VST and
262 gigedit on systems with other GTK versions installed)
263
264 * audio driver:
265 - removed the nonsense audio channel constraint (which was hard coded to
266 max. 100 audio channels) for most audio drivers
267 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
268 opposed to the LSCP specs
269 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
270 reflected the wrong value
271 - fixed a memory management bug in ASIO driver
272 - Makefile fix: JACK_CFLAGS wasn't used
273 - JACK: use jack_client_open instead of the deprecated
274 jack_client_new
275 - added (experimental) CoreAudio driver
276 - applied old fixes to the ASIO driver that were included in the
277 previous binary release but accidentally never committed to CVS
278 (fixes #117)
279 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
280 win64)
281 - VST: added support for sample rate and buffer size changes
282 - VST: close editor (Fantasia) when the VST is removed
283 - VST: avoid opening Fantasia more than once for each VST instance
284 - VST: export main function as "main" on Linux too (fix for
285 energyXT)
286 - VST: changed number of output channels from one stereo to 16
287 stereo
288 - added channel routing, fxsends and midi maps to the settings
289 stored in the plugin state
290 - performance optimization of AudioChannel::MixTo() and
291 AudioChannel::CopyTo() methods using GCC vector exensions
292 (if available)
293 - ASIO fixes: avoid initializing the device twice, avoid throwing
294 exception when getting parameters from a disconnected device
295
296 * MIDI driver:
297 - added JACK MIDI driver
298 - dispatch bank select as ordinary CC as well, the user might seriously
299 want to (mis)use it for some purpose ("fixed" in all current MIDI
300 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
301 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
302 CoreMidi or AU
303 - fixed mingw-w64 compilation error in MME driver
304 - made program change handling in MIDI thread real-time safe by
305 moving the logic to a non-RT thread
306 - fixed minor memory leak in ALSA driver
307
308 * instruments database:
309 - avoid time consuming samples scanning when adding instruments
310 to the instruments database
311 - added support for handling lost files in the instruments database
312 - Implemented option for adding instruments in separate directories
313 in the instruments database
314 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
315 - work-around for missing fnmatch function on Windows to make
316 instrument database compilable
317 - added instrument database support on Windows
318 works with both standalone mode and VST plugin.
319 the instruments DB file is located in
320 %USERPROFILE%\.linuxsampler\instruments.db which allows different
321 databases for each windows user
322 if no DB is present it automatically creates the .linuxsampler subdir
323 and then creates an empty DB
324 - fixed recursive import, which was broken on Windows
325
326 * Gigasampler format engine:
327 - fixed a memory leak that could happen when a channel was deleted
328 while notes were playing
329 - made it possible to load an instrument even if the audio thread
330 isn't running
331 - added partial support for the "Controller Triggered" MIDI rule,
332 enough for piano gigs with pedal noise samples
333 - minor fix: only mark FX sends as being modified if really the
334 respective FX send MIDI controller was used
335 - added support for GM global device volume SysEx message
336 (can be selected at compile time to either apply globally to the
337 whole sampler [default] or only to the sampler channels that are
338 connected to the respective MIDI input port the SysEx message arrived
339 on)
340 - bugfix: notes triggered at position 0 in the audio buffer were
341 sometimes wrongly killed in the same buffer, causing no sound to
342 be played
343 - added support for chromatic / drumkit mode Roland GS Sysex message
344 which is usally used to switch a part between chromatic sounds and
345 drumkit sounds (as opposed to their common default setting of MIDI
346 part 10 being a drumkit part and all other ones chromatic parts), in
347 LS however one can switch between the first 16 MIDI instrument maps
348 defined for the sampler
349 - made it possible to create multiple sample channels even if the
350 audio thread isn't running
351 - fixed crash when removing channel with active voices (#116)
352 - bugfix: on sample reference changes (instrument editor), only
353 un-cache the respective sample if it's really not used by any
354 sampler engine anymore
355 - re-cache samples in case they were changed by an instrument editor,
356 e.g. when a sample was added while playing (#82)
357 - fixed hanging notes which occured when note-off event had the exact
358 same time stamp as the voice's note-on event and occured both in the
359 same audio fragment cycle (fixes bug #112)
360 - added support for the "fine tune" and "pitch bend range"
361 instrument-level gig parameters
362 - fixed minor artifacts in pitch bend handling
363 - added support for GS Reset SysEx message
364 - allow gig files to use unlimited downward pitch shifting
365 - added a limit check for upward pitch shifting
366 - bugfix: sometimes, when playing a note twice fast, the second
367 note was silent
368 - fixed crash happening when a pitch bend event arrived at the
369 same time a new instrument was loading
370
371 * LSCP server:
372 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
373 react on MIDI data arriving on certain sampler channels (so far only
374 Note-On and Note-Off events are sent via this LSCP event)
375 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
376 react on MIDI data arriving on certain MIDI input devices (so far only
377 Note-On and Note-Off events are sent via this LSCP event)
378 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
379 SET DB_INSTRUMENT FILE_PATH
380 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
381 frontends to send MIDI messages to specific sampler channel
382 - added two additional fields to GET FILE INSTRUMENT INFO command -
383 KEY_BINDINGS and KEYSWITCH_BINDINGS
384 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
385 was incorrect
386 - Optimized the retrieval of the MIDI instrument mappings
387 - added new LSCP command "SET VOICES" to globally alter the maximum
388 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
389 be triggered respectively
390 - added new LSCP command "SET STREAMS" to globally alter the maximum
391 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
392 which will be triggered respectively
393 - bugfix: retry if "select" returns EINTR (this fixes a crash when
394 a gigedit file dialog is opened)
395 - close all connections when LSCPServer is deleted
396 - hard close of all sockets on exit
397 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
398 driver
399
400 * Bug fixes:
401 - fixed a crash which occurs when removing a sampler channel waiting
402 to start instrument loading after another channel
403 - fixed a crash which occurs when removing a sampler channel with
404 instrument loading in progress (bug #113)
405 - fixed termination caused by uncaught exception when adding MIDI
406 instrument with PERSISTENT load mode
407 - fixed possible iterator invalidations when resetting the sampler
408 - fixed memory leaks when issuing the following LSCP commands:
409 GET AUDIO_OUTPUT_DRIVER INFO
410 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
411 GET MIDI_INPUT_DRIVER INFO
412 GET MIDI_INPUT_DRIVER_PARAMETER INFO
413 - fixed possible compilation error when sqlite is not present
414 - fixed orphaned pointers when setting maximum voices limit (bug #118)
415 - fixed crash when changing the audio output device of a sampler
416 channel with loaded instrument and start playing notes
417 - fixed endless loop in Engine::SuspendAll() (bug #120)
418 - fixed a low-level atomic load function that was broken on 64-bit
419 PowerPC, which probably could cause crashes on that platform
420 - fixed a memory management error which could cause a crash when a
421 plugin was unloaded
422 - bugfix: two private structs had the same name, which could cause
423 problems if the linker chose the wrong constructor
424 - fixed low-level ConditionServer usage bug that caused lockups on
425 Windows
426
427
428 Version 0.5.1 (6 December 2007)
429
430 * packaging changes:
431 - added autoconf checks for pthread library
432 - added autoconf check for pthread bug found on certain NPTL-enabled
433 glibc versions (see Gentoo bug report #194076)
434 - added autoconf checks for MS Windows
435
436 * general changes:
437 - bugfix: the thread used by an editor plugin didn't die when the
438 editor closed
439 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
440 out all the space. operator--() did not apply size_mask after
441 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
442 order to avoid problems with the _NonVolatileReader functions.
443 - bugfix: Stream.h: added a missing divide by BytesPerSample in
444 GetWriteSpace(). Since this function is currently only used in
445 the stream's qsort() compare function, it didn't trigger any
446 bugs.
447 - Resampler.h, Synthesizer.h: cubic interpolation now works in
448 24bit mode too. Faster method to read 24bit words on little
449 endian machines (x86): replaced 3 byte reads + shifts with a 1
450 unaligned 32bit read and shift
451 - experimental support for MS Windows (MIDI input via MME, AUDIO
452 output via ASIO)
453 - made handling of SIGINT signal (Ctrl-C) a bit more robust
454 - support for monitoring the total number of active disk streams
455 (new LSCP commands: GET TOTAL_STREAM_COUNT,
456 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
457
458 * AUDIO driver:
459 - added Windows ASIO low latency audio driver
460
461 * MIDI driver:
462 - added MME Windows MIDI driver
463
464 * LSCP server:
465 - added support for Windows style path / filenames, however with
466 forward slash path separators instead of backslash
467 (i.e. "C:/foo/bar.gig")
468 - allow naughty liblscp to send non-string device parameters within
469 apostrophes as well
470 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
471 "LIST FILE INSTRUMENTS <file>" and
472 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
473 about an arbitrary instrument file on the system where the sampler is
474 running on
475
476 Version 0.5.0 (15 October 2007)
477
478 * packaging changes:
479 - config.h is not going to be installed along with liblinuxsampler's
480 API header files anymore
481 - only the API relevant header (and source) files will be exported to
482 the Doxygen API documentation (explicitly listed in Doxyfile.in)
483 - added completely new XCode project files for Mac OSX which is now
484 capable to execute our autoconf environment, thus no need anymore
485 to maintain the compile time configuration file (osx/version.h) for
486 OSX manually (patch by Toshi Nagata)
487 - fixed buggy boolean --enable-foo / --disable-foo configure script
488 parameters
489 - global.h now only covers global definitions that are needed for the
490 C++ API header files, all implementation internal global definitions
491 are now in global_private.h
492 - atomic.h is not exposed to the C++ API anymore
493 - no need to include config.h anymore for using LS's API header files
494 - fixed warnings in API doc generation
495
496 * general changes:
497 - replaced the old, confusing MIDI program change mechanism by a
498 flexible MIDI instrument mapper which allows to map arbitrary
499 (MIDI bank, MIDI program) pairs with arbitrary
500 (engine type, instrument file, file index) triplets which will be
501 loaded on the respective channel when such MIDI program change
502 messages arrive, beside that, each entry allows to define a life-time
503 strategy for the instrument, so the user can define whether the
504 instrument should i.e. be permanently loaded (to be able to switch
505 quickly among sounds) or i.e. loaded just on demand when the
506 respective program change arrives (to safe RAM space), as well as a
507 global volume factor for each entry, so the user can adjust the volume
508 dynamic of his mapped instrument collection without having to modify
509 the instrument files, also one can manage arbitrary amount of such
510 MIDI instrument maps and assign each sampler channel individually
511 a certain map, so that i.e. separation of normal instruments and
512 drumkits is possible
513 - new notification events for tracking changes to audio/MIDI devices,
514 MIDI instrument maps, MIDI instruments, FX sends, global volume.
515 - sampler was limited to load max. 200 instruments in the background
516 due to a constant size RingBuffer FIFO which is now replaced by a
517 dynamic (unlimited) size std::list FIFO
518 - added FX sends, these allow to route audio signals to arbitrary audio
519 output channels for being processed by external effect processors
520 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
521 controllers
522 - global (sampler wide) volume can now be controlled at runtime
523 - Implemented new, improved notification system
524 - fixed compilation errors regarding OSX
525 (patch by Toshi Nagata)
526 - implemented instruments database
527 - added support for escape sequences to the instruments database
528 - added highly experimental support for on-the-fly instrument editing
529 within the sampler's process (by using instrument editor plugins),
530 you'll notice the new "Registered instrument editors:" message on
531 startup, added a new LSCP command:
532 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
533 to spawn a matching instrument editor for the instrument on the
534 given sampler channel, the plugin path can be overridden at compile
535 time with ./configure --enable-plugin-dir=/some/dir
536 - added experimental code for synchronizing instrument editors hosted
537 in the sampler's process to safely edit instruments while playing
538 without a crash (hopefully) by either suspending single regions
539 wherever possible or if unavoidable whole engine(s)
540 - fixed several issues in fundamental "Thread" class: set scheduling
541 policy and priority on thread level, set a minimum stack size for
542 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
543 threads simply inherited properties of starting thread instead of
544 setting their own policy and priority
545 - minor fix in our automatic stack trace mechanism on crashes, the
546 main process did not wait for the stack trace process to finish
547 its output
548 - fixed some minor memory leaks
549 - reenabled assembly features support, at the moment only for
550 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
551 - minor assembly fix in x86 features detection (don't use the PIC
552 register, to avoid relocations in the text segment at runtime)
553 - POSIX callback functions of Thread.h are hidden
554
555 * MIDI driver:
556 - dispatch bank select (MSB and LSB) messages
557
558 * audio driver:
559 - the ALSA audio output driver parameters now reflect the correct
560 parameter value ranges for the respective selected sound card
561 (patch by Till Wimmer, a bit fixed and extended)
562
563 * Gigasampler format engine:
564 - if a filter is used and EG2 finishes before EG1, let the voice
565 die when EG2 has finished (this fixes a problem with clicks and
566 voice starvation for some gigs)
567 - playback is no longer disabled during instrument loading
568 - all notes playing on a channel that changes its instrument keep
569 playing with the old instrument until they get a note off
570 command
571 - EG fix: a release value of zero could cause noises or crash
572 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
573 - EG fine tuning: when attack is zero the EG starts at a level
574 above max sustain level, which means that there is a decay phase
575 even if sustain is 100%
576 - more EG fixes: the level could sometimes go below zero and cause
577 noises or crashes
578 - minor fix of EGDecay (patch by Toshi Nagata)
579 - fixed compiler error when --enable-override-filter-type was
580 supplied to the configure script (fixes #46)
581 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
582 instead of a fix value
583 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
584 127 (solo mode) only kill voices if the respective mode really
585 changed
586
587 * LSCP server:
588 - fixed compile time error for old Bison versions
589 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
590 - parser now supports extended ASCII character set
591 (up to ASCII code 255, i.e. includes now umlauts and accents)
592 - filename arguments in LSCP commands now allow to use escape
593 sequences, that is directly literal as one of: \', \", \\, \n, \r,
594 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
595 code value like \xf2) (fixes bug #24)
596 - the following LSCP commands now also support escape sequences for at
597 least one of their text-based parameters (i.e. name, description):
598 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
599 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
600 "SET DB_INSTRUMENT_DIRECTORY NAME",
601 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
602 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
603 "FIND DB_INSTRUMENT_DIRECTORIES"
604 - returns verbose syntax errors (line and column where syntax error
605 occured, the unexpected character and the actually expected, possible
606 character(s), the latter only if less than 5 possibilities)
607 - made sure that LSCP syntax is not affected by gigedit locale
608 settings
609 - bugfix regarding strings parameter lists: all comma separated lists
610 of strings were treated as being one string containing commas
611 (fixes #57)
612
613 * Bug fixes:
614 - fixed crash occurring on certain LSCP scripts (Bug 39)
615 - another thread safety fix for lscp "load engine" and "set
616 channel audio output device"
617 - fixed a crash which occurs when reassigning the same engine
618 on a sampler channel with connected MIDI device
619 - fixed a crash which occurs when changing the number of ports of a MIDI
620 device connected to a sampler channel to number less then or equal
621 to the index of the port to which the sampler channel is connected.
622 - The previous bindings were not been disconnected when altering
623 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
624 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
625 - The active stream/voice count statistic was incorrect.
626 - notification events were not been sent for some sampler
627 channel changes
628 - added default min and max values to restrict the number of allowed
629 audio output channels and MIDI input ports
630 - the connection to the PCM interface is now closed when destroying
631 an audio output device
632 - files with slash in their path or filename could not be loaded
633
634 * test cases:
635 - updated and fixed (haven't been touched in a while)
636
637 Version 0.4.0 (24 November 2006)
638
639 * packaging changes:
640 - changed deprecated copyright attribute to license; added ldconfig
641 to post-(un)install steps; added devel package for liblinuxsampler;
642 to linuxsampler.spec (RPM)
643 - install necessary development header files for allowing 3rd party
644 applications to link against liblinuxsampler
645 - liblinuxsampler's API documentation can be generated with 'make docs'
646 (Doxygen required)
647 - added benchmark to automatically detect the best triangle LFO
648 implementation (currently either an integer math solution or a
649 di-harmonic approximation), automatic detection can be overriden
650 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
651 configure script argument though (mandatory for cross-compilation)
652 - do not automatically pick optimized gcc flags if the user already
653 provided some on his own (as CXXFLAGS)
654 - added compile time option to disable processing of All-Notes-Off MIDI
655 messages
656 - added compile time options to allow disabling the various audio and
657 MIDI drivers
658 - fixed automatic GCC CPU switch detection on PPC
659 (patch by Ebrahim Mayat)
660
661 * Gigasampler format engine:
662 - extensive synthesis optimization
663 (reimplementation of EGs and LFO(s), removed synthesis parameter
664 prerendering and the synthesis parameter matrix in general, splitting
665 each audio fragment into subfragments now where each subfragment uses
666 constant pitch and filter coefficients. The volume coefficient is
667 linearly interpolated inside a subfragment, unless
668 --disable-interpolate-volume is set.)
669 - fine tuning of the EG modulation parameters
670 - improved filter cutoff calculation by adding support for the
671 following gig parameters: Cutoff freq (used when no cutoff
672 controller is defined), Control invert, Minimum cutoff, Velocity
673 curve and Velocity range. The keyboard tracking now scales
674 cutoff frequency instead of resonance.
675 - added support for gig parameter Resonance.
676 - fixed bug in sysex handling (patch by Juan Linietsky)
677 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
678 which can be overridden with --enable-global-attenuation
679 - EG fixes: made the length of "attack hold" stage more
680 accurate. Release stage can now start before attack stage
681 ends. Cancel release didn't work when sustain was zero. Attack
682 time now has a minimal value to prevent clicks.
683 - fixed pitch changes larger than one octave
684 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
685 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
686 all modes can be altered via standard GM messages, that is CC5 for
687 altering portamento time, CC65 for enabling / disabling portamento
688 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
689 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
690 parameter) and crossfade
691 - added support for the "attenuation controller threshold" gig
692 parameter
693 - added smoothing of volume changes caused by control change
694 messages
695 - sample loop parameters are now taken from the DimensionRegion
696 instead of the wave chunk
697 - fixed keyswitching for v3 gigs with a number of keyswitch splits
698 not equal to a power of two
699 - reimplementation of the filter algorithm. The new filter is more
700 accurate and supports all gig filter types, including bandreject
701 and lowpass turbo.
702 - real support for 24 bit samples - samples are not truncated to
703 16 bits anymore
704 - support for aftertouch (channel pressure, not polyphonic
705 aftertouch)
706 - LFO1 behaviour fixed (dampening from max volume instead of
707 amplifying from 0)
708
709 * LSCP server:
710 - fixed application exit on broken pipe error (fixes bug #20)
711 - fixed the notification messages delay due to lack of
712 network activity (fixes bug #26)
713 - fixed parser bug which occured on space(s) within device parameters
714 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
715
716 * audio driver:
717 - added aRts audio output driver (by no means RT safe)
718
719 * MIDI driver:
720 - fixed legacy sysex code which caused dispatching of MIDI SysEx
721 messages several times instead of once
722 - API extension for MIDI drivers which already supply exact time stamps
723 for events (i.e. for offline rendering based MIDI drivers)
724 - added checks for bad MIDI data
725
726 * linuxsampler application:
727 - show available sampler engine types on startup
728
729 * general changes:
730 - support for muting sampler channels and solo mode of the same, two new
731 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
732 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
733 introduced for this, the behavior is the same like on a mixer console
734 (patch by Grigor Iliev, a bit adjusted). Also added configure option
735 --enable-process-muted-channels which can be used to enable the
736 processing of muted channels.
737 - support for sostenuto pedal
738 - support for monitoring the total number of active voices
739 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
740 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
741 - fixed some memory management errors
742 - fixed some concurrency problems that could lead to crashes when
743 LSCP commands were executed
744 - fixed crash when instrument loading failed previously on the same
745 sampler channel (fixes bug #36)
746
747 Version 0.3.3 (15 July 2005)
748
749 * packaging changes:
750 - fixed compilation with gcc 4.0
751
752 * Gigasampler format engine:
753 - LFO preprocessing was performed even though the respective LFO was
754 disabled by the instrument patch (minor efficiency fix)
755 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
756 for volume ramp downs in the same fragment (needed for current voice
757 stealing implementation) then simply inform the user with a warning
758 about possible click sounds and reduce the volume ramp down
759 appropriately instead of cancelling the audio device connection
760
761 Version 0.3.2 (24 June 2005)
762
763 * packaging changes:
764 - updated autotools build files to compile on OS X
765 (conditional compilation of CoreMIDI and MidiShare drivers)
766 - hand-crafted assembly optimization code can be disabled with
767 './configure --disable-asm' (definitely not recommended)
768 - fixed 'make dist' rule to include all necessary files
769 - require automake (>= 1.5) for 'make -f Makefile.cvs'
770 (due to 'dist-bzip2' automake option)
771
772 * Gigasampler format engine:
773 - support for the gig parameters for "release velocity response" curves
774 - fine tuning of the EGADSR envelope
775 - volume of release triggered samples now depends on note-on velocity,
776 note length and gig parameter "release trigger decay" instead of
777 note-off velocity.
778 - revised voice stealing
779 (fixes crash and endless loop caused by voice stealing)
780 - don't reset scale tuning on instrument or audio output device change
781 - handle key group conflicts right at the beginning of each fragment
782 instead of when the respective voice is actually launched
783 (fixes undefined behavior if stolen voices belonged to a key group -
784 this case was followed by a "killed voice survived" error message)
785 - fixed minor issue with null/silence samples
786 (those stole voices even though they don't need a voice at all which
787 resulted in "voice stealing didn't work out" messages)
788 - don't reset volume, pan, pitch and MIDI controller values on
789 instrument or audio output device change
790
791 * LSCP server:
792 - fixed some crashes (patch by Grigor Iliev, fixes #19)
793 - fixed LSCP event "CHANNEL_INFO" notification
794 (e.g. did not notify on volume changes or MIDI program change events)
795
796 * linuxsampler application:
797 - added command line parameters --lscp-addr and --lscp-port to override
798 default IP address and port of LSCP server
799
800 Version 0.3.1 (24 May 2005)
801
802 * initial release
