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 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
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)

115 * Host plugins:
116 - AU bugfix: failed to destroy its audio/MIDI devices
117 - Listen to all interfaces on Mac OS X (INADDR_ANY)
118 - VST bugfix: If the host called resume() before and after
119 changing sample rate or block size, the number of channels was
120 incorrectly set to two. This caused silence in Cubase 5.
121 - save engine type (gig, sfz or sf2) in plugin state
122 - VST: when opening Fantasia, look for both 32 and 64 bit Java on
123 64 bit Windows
124 - AU: changed number of output channels from one stereo to 16

126 - VST: made it possible to build the VST plugin for Mac
127 - AU: link AU plugin dynamically if --disable-shared isn't
128 specified
130 * MIDI driver:
131 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
132 the ALSA sequencer client name

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