* AU: changed number of output channels from one stereo to 16 stereo
* VST: made it possible to build the VST plugin for Mac
* AU: link AU plugin dynamically if --disable-shared isn't specified
* minor Makefile fix for building lscpparser when build and source
  directories are separate

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

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

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.

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)

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