* sfz engine: implemented opcode volume_smoothccN

1 Version CVS HEAD (?)
2
3 * plugin changes:
4 - LV2 Persist + Files support (patch by David Robillard)
5
6 * packaging changes:
7 - fixed building with newer MinGW-w64
8 - Mac OS X: support the new dir for Core Audio SDK
9 - Mac OS X: fixed building outside source directory
10 - made sure all source files for hostplugins are included when
11 doing "make dist"
12 - removed empty directories left from the cvs to svn migration
13 - fixed compilation with gcc 4.6.1
14 - another "make dist" fix, for 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)

159 * MIDI driver:
160 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
161 the ALSA sequencer client name
162 - removed limit of maximum amount of MIDI ports per MIDI device, since
163 there is no reason for this limit

207 - minor valgrind fixes
208 - fixed crash which occurred when changing an already deployed sampler
209 channel to a different engine type
210 - fixed crash when deleting a sampler channel or changing engine
211 type while an instrument load was in progress
212 - bugfix: playing a note while changing the instrument could cause
213 a crash, or give "Handing back unknown region" error messages
214 - bugfix: calling SET VOICES (which Fantasia does on start and
215 refresh) could cause instruments to be unloaded
216 - Mac OS X: fixed name collision of enum in EffectControl and

223
224 Version 1.0.0 (31 July 2009)
225
226 * packaging changes:
227 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
228 causing e.g. the libgig test to fail when
229 "./configure --disable-jack-driver" was used
230 (patch by Alexis Ballier)
231 - fixed compilation with gcc 4.3
232 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
233 - fixed configure so it detects x86_64 (#107)
234 - fixes for building with newer MinGW versions
235 - fix for building with bison 2.4 (#111)
236 - fixed building with libgig installed in a non-standard directory
237 - minor fix in configure for mmsystem.h detection on MinGW
238 - Windows: look for editor plugins and Fantasia using base
239 directory of liblinuxsampler dll (look in the same directory and one
240 directory above)
241 - configure script fix: removed unconditional use of SSE
242 - fixed building with sqlite installed in a non-standard directory
243 - when cross-compiling, don't try to create instruments.db
244 - fix for new mingw-w64 version, which has usleep
245
246 * general changes:
247 - bugfix: on some POSIX systems instrument editor plugins refused to
248 load as we used a non-portable Linux specific struct field
249 (fixes bug #70, patch by Ronald Baljeu)
250 - fixed endless loop which occured when loading an instrument editor
251 plugin DLL on Windows systems failed
252 - fixed memory leaks that occurred when liblinuxsampler was unloaded
253 - optimized the SynchronizedConfig class so it doesn't wait
254 unnecessarily long after an update
255 - added support for notifying instrument editors on note-on / note-off
256 events (e.g. to highlight the pressed keys on the virtual keyboard
257 of gigedit)
258 - added support for triggering notes by instrument editors (see above)
259 - be verbose on DLL load errors (on Linux)
260 - fixed di-harmonic triangle LFO implementation (this LFO implementation
261 is only used by very few systems, most pick the int math
262 implementation, which is usually faster)
263 - fixes for audio drivers with varying buffer sizes
264 - experimental support for running LinuxSampler as a DSSI, LV2 and
265 VST plugin
266 - notification events for stream/voice count statistics are now sent
267 only when there are actual changes
268 - added memory ordering constraints to improve stability on
269 multi-core and multi-cpu systems
270 - maximum voices and disk streams can now be altered at runtime
271 - fixed CPU feature detection on x86_64 (maybe fixes #108)
272 - automatic stacktrace mechanism is now turned off by default and can
273 be switched on by command line option "--stacktrace" (the automatic
274 stacktrace mechanism seems to be broken on most systems at the moment)
275 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
276 a pointer to the launched InstrumentEditor object
277 - added optional 3rd party user data parameter for following
278 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
279 InstrumentEditor::Launch(),
280 InstrumentManager::LaunchInstrumentEditor()
281 - theoretical fix: made SynchronizedConfig follow C++0x memory
282 model more strictly
283 - fixes for using large audio device buffers
284 - Windows: add the installation directory to the DLL search path
285 when loading an editor plugin (solves problems with VST and
286 gigedit on systems with other GTK versions installed)
287
288 * audio driver:
289 - removed the nonsense audio channel constraint (which was hard coded to
290 max. 100 audio channels) for most audio drivers
291 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
292 opposed to the LSCP specs
293 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
294 reflected the wrong value
295 - fixed a memory management bug in ASIO driver
296 - Makefile fix: JACK_CFLAGS wasn't used
297 - JACK: use jack_client_open instead of the deprecated
298 jack_client_new
299 - added (experimental) CoreAudio driver
300 - applied old fixes to the ASIO driver that were included in the
301 previous binary release but accidentally never committed to CVS
302 (fixes #117)
303 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
304 win64)
305 - VST: added support for sample rate and buffer size changes
306 - VST: close editor (Fantasia) when the VST is removed
307 - VST: avoid opening Fantasia more than once for each VST instance
308 - VST: export main function as "main" on Linux too (fix for
309 energyXT)
310 - VST: changed number of output channels from one stereo to 16
311 stereo
312 - added channel routing, fxsends and midi maps to the settings
313 stored in the plugin state
314 - performance optimization of AudioChannel::MixTo() and
315 AudioChannel::CopyTo() methods using GCC vector exensions
316 (if available)
317 - ASIO fixes: avoid initializing the device twice, avoid throwing
318 exception when getting parameters from a disconnected device
319
320 * MIDI driver:
321 - added JACK MIDI driver
322 - dispatch bank select as ordinary CC as well, the user might seriously
323 want to (mis)use it for some purpose ("fixed" in all current MIDI
324 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
325 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
326 CoreMidi or AU
327 - fixed mingw-w64 compilation error in MME driver
328 - made program change handling in MIDI thread real-time safe by
329 moving the logic to a non-RT thread
330 - fixed minor memory leak in ALSA driver
331
332 * instruments database:
333 - avoid time consuming samples scanning when adding instruments
334 to the instruments database
335 - added support for handling lost files in the instruments database
336 - Implemented option for adding instruments in separate directories
337 in the instruments database
338 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
339 - work-around for missing fnmatch function on Windows to make
340 instrument database compilable
341 - added instrument database support on Windows
342 works with both standalone mode and VST plugin.
343 the instruments DB file is located in
344 %USERPROFILE%\.linuxsampler\instruments.db which allows different
345 databases for each windows user
346 if no DB is present it automatically creates the .linuxsampler subdir
347 and then creates an empty DB
348 - fixed recursive import, which was broken on Windows
349
350 * Gigasampler format engine:
351 - fixed a memory leak that could happen when a channel was deleted
352 while notes were playing
353 - made it possible to load an instrument even if the audio thread
354 isn't running
355 - added partial support for the "Controller Triggered" MIDI rule,
356 enough for piano gigs with pedal noise samples
357 - minor fix: only mark FX sends as being modified if really the
358 respective FX send MIDI controller was used
359 - added support for GM global device volume SysEx message
360 (can be selected at compile time to either apply globally to the
361 whole sampler [default] or only to the sampler channels that are
362 connected to the respective MIDI input port the SysEx message arrived
363 on)
364 - bugfix: notes triggered at position 0 in the audio buffer were
365 sometimes wrongly killed in the same buffer, causing no sound to
366 be played
367 - added support for chromatic / drumkit mode Roland GS Sysex message
368 which is usally used to switch a part between chromatic sounds and
369 drumkit sounds (as opposed to their common default setting of MIDI
370 part 10 being a drumkit part and all other ones chromatic parts), in
371 LS however one can switch between the first 16 MIDI instrument maps
372 defined for the sampler
373 - made it possible to create multiple sample channels even if the
374 audio thread isn't running
375 - fixed crash when removing channel with active voices (#116)
376 - bugfix: on sample reference changes (instrument editor), only
377 un-cache the respective sample if it's really not used by any
378 sampler engine anymore
379 - re-cache samples in case they were changed by an instrument editor,
380 e.g. when a sample was added while playing (#82)
381 - fixed hanging notes which occured when note-off event had the exact
382 same time stamp as the voice's note-on event and occured both in the
383 same audio fragment cycle (fixes bug #112)
384 - added support for the "fine tune" and "pitch bend range"
385 instrument-level gig parameters
386 - fixed minor artifacts in pitch bend handling
387 - added support for GS Reset SysEx message
388 - allow gig files to use unlimited downward pitch shifting
389 - added a limit check for upward pitch shifting
390 - bugfix: sometimes, when playing a note twice fast, the second
391 note was silent
392 - fixed crash happening when a pitch bend event arrived at the
393 same time a new instrument was loading
394
395 * LSCP server:
396 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
397 react on MIDI data arriving on certain sampler channels (so far only
398 Note-On and Note-Off events are sent via this LSCP event)
399 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
400 react on MIDI data arriving on certain MIDI input devices (so far only
401 Note-On and Note-Off events are sent via this LSCP event)
402 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
403 SET DB_INSTRUMENT FILE_PATH
404 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
405 frontends to send MIDI messages to specific sampler channel
406 - added two additional fields to GET FILE INSTRUMENT INFO command -
407 KEY_BINDINGS and KEYSWITCH_BINDINGS
408 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
409 was incorrect
410 - Optimized the retrieval of the MIDI instrument mappings
411 - added new LSCP command "SET VOICES" to globally alter the maximum
412 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
413 be triggered respectively
414 - added new LSCP command "SET STREAMS" to globally alter the maximum
415 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
416 which will be triggered respectively
417 - bugfix: retry if "select" returns EINTR (this fixes a crash when
418 a gigedit file dialog is opened)
419 - close all connections when LSCPServer is deleted
420 - hard close of all sockets on exit
421 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
422 driver
423
424 * Bug fixes:
425 - fixed a crash which occurs when removing a sampler channel waiting
426 to start instrument loading after another channel
427 - fixed a crash which occurs when removing a sampler channel with
428 instrument loading in progress (bug #113)
429 - fixed termination caused by uncaught exception when adding MIDI
430 instrument with PERSISTENT load mode
431 - fixed possible iterator invalidations when resetting the sampler
432 - fixed memory leaks when issuing the following LSCP commands:
433 GET AUDIO_OUTPUT_DRIVER INFO
434 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
435 GET MIDI_INPUT_DRIVER INFO
436 GET MIDI_INPUT_DRIVER_PARAMETER INFO
437 - fixed possible compilation error when sqlite is not present
438 - fixed orphaned pointers when setting maximum voices limit (bug #118)
439 - fixed crash when changing the audio output device of a sampler
440 channel with loaded instrument and start playing notes
441 - fixed endless loop in Engine::SuspendAll() (bug #120)
442 - fixed a low-level atomic load function that was broken on 64-bit
443 PowerPC, which probably could cause crashes on that platform
444 - fixed a memory management error which could cause a crash when a
445 plugin was unloaded
446 - bugfix: two private structs had the same name, which could cause
447 problems if the linker chose the wrong constructor
448 - fixed low-level ConditionServer usage bug that caused lockups on
449 Windows
450
451
452 Version 0.5.1 (6 December 2007)
453
454 * packaging changes:
455 - added autoconf checks for pthread library
456 - added autoconf check for pthread bug found on certain NPTL-enabled
457 glibc versions (see Gentoo bug report #194076)
458 - added autoconf checks for MS Windows
459
460 * general changes:
461 - bugfix: the thread used by an editor plugin didn't die when the
462 editor closed
463 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
464 out all the space. operator--() did not apply size_mask after
465 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
466 order to avoid problems with the _NonVolatileReader functions.
467 - bugfix: Stream.h: added a missing divide by BytesPerSample in
468 GetWriteSpace(). Since this function is currently only used in
469 the stream's qsort() compare function, it didn't trigger any
470 bugs.
471 - Resampler.h, Synthesizer.h: cubic interpolation now works in
472 24bit mode too. Faster method to read 24bit words on little
473 endian machines (x86): replaced 3 byte reads + shifts with a 1
474 unaligned 32bit read and shift
475 - experimental support for MS Windows (MIDI input via MME, AUDIO
476 output via ASIO)
477 - made handling of SIGINT signal (Ctrl-C) a bit more robust
478 - support for monitoring the total number of active disk streams
479 (new LSCP commands: GET TOTAL_STREAM_COUNT,
480 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
481
482 * AUDIO driver:
483 - added Windows ASIO low latency audio driver
484
485 * MIDI driver:
486 - added MME Windows MIDI driver
487
488 * LSCP server:
489 - added support for Windows style path / filenames, however with
490 forward slash path separators instead of backslash
491 (i.e. "C:/foo/bar.gig")
492 - allow naughty liblscp to send non-string device parameters within
493 apostrophes as well
494 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
495 "LIST FILE INSTRUMENTS <file>" and
496 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
497 about an arbitrary instrument file on the system where the sampler is
498 running on
499
500 Version 0.5.0 (15 October 2007)
501
502 * packaging changes:
503 - config.h is not going to be installed along with liblinuxsampler's
504 API header files anymore
505 - only the API relevant header (and source) files will be exported to
506 the Doxygen API documentation (explicitly listed in Doxyfile.in)
507 - added completely new XCode project files for Mac OSX which is now
508 capable to execute our autoconf environment, thus no need anymore
509 to maintain the compile time configuration file (osx/version.h) for
510 OSX manually (patch by Toshi Nagata)
511 - fixed buggy boolean --enable-foo / --disable-foo configure script
512 parameters
513 - global.h now only covers global definitions that are needed for the
514 C++ API header files, all implementation internal global definitions
515 are now in global_private.h
516 - atomic.h is not exposed to the C++ API anymore
517 - no need to include config.h anymore for using LS's API header files
518 - fixed warnings in API doc generation
519
520 * general changes:
521 - replaced the old, confusing MIDI program change mechanism by a
522 flexible MIDI instrument mapper which allows to map arbitrary
523 (MIDI bank, MIDI program) pairs with arbitrary
524 (engine type, instrument file, file index) triplets which will be
525 loaded on the respective channel when such MIDI program change
526 messages arrive, beside that, each entry allows to define a life-time
527 strategy for the instrument, so the user can define whether the
528 instrument should i.e. be permanently loaded (to be able to switch
529 quickly among sounds) or i.e. loaded just on demand when the
530 respective program change arrives (to safe RAM space), as well as a
531 global volume factor for each entry, so the user can adjust the volume
532 dynamic of his mapped instrument collection without having to modify
533 the instrument files, also one can manage arbitrary amount of such
534 MIDI instrument maps and assign each sampler channel individually
535 a certain map, so that i.e. separation of normal instruments and
536 drumkits is possible
537 - new notification events for tracking changes to audio/MIDI devices,
538 MIDI instrument maps, MIDI instruments, FX sends, global volume.
539 - sampler was limited to load max. 200 instruments in the background
540 due to a constant size RingBuffer FIFO which is now replaced by a
541 dynamic (unlimited) size std::list FIFO
542 - added FX sends, these allow to route audio signals to arbitrary audio
543 output channels for being processed by external effect processors
544 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
545 controllers
546 - global (sampler wide) volume can now be controlled at runtime
547 - Implemented new, improved notification system
548 - fixed compilation errors regarding OSX
549 (patch by Toshi Nagata)
550 - implemented instruments database
551 - added support for escape sequences to the instruments database
552 - added highly experimental support for on-the-fly instrument editing
553 within the sampler's process (by using instrument editor plugins),
554 you'll notice the new "Registered instrument editors:" message on
555 startup, added a new LSCP command:
556 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
557 to spawn a matching instrument editor for the instrument on the
558 given sampler channel, the plugin path can be overridden at compile
559 time with ./configure --enable-plugin-dir=/some/dir
560 - added experimental code for synchronizing instrument editors hosted
561 in the sampler's process to safely edit instruments while playing
562 without a crash (hopefully) by either suspending single regions
563 wherever possible or if unavoidable whole engine(s)
564 - fixed several issues in fundamental "Thread" class: set scheduling
565 policy and priority on thread level, set a minimum stack size for
566 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
567 threads simply inherited properties of starting thread instead of
568 setting their own policy and priority
569 - minor fix in our automatic stack trace mechanism on crashes, the
570 main process did not wait for the stack trace process to finish
571 its output
572 - fixed some minor memory leaks
573 - reenabled assembly features support, at the moment only for
574 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
575 - minor assembly fix in x86 features detection (don't use the PIC
576 register, to avoid relocations in the text segment at runtime)
577 - POSIX callback functions of Thread.h are hidden
578
579 * MIDI driver:
580 - dispatch bank select (MSB and LSB) messages
581
582 * audio driver:
583 - the ALSA audio output driver parameters now reflect the correct
584 parameter value ranges for the respective selected sound card
585 (patch by Till Wimmer, a bit fixed and extended)
586
587 * Gigasampler format engine:
588 - if a filter is used and EG2 finishes before EG1, let the voice
589 die when EG2 has finished (this fixes a problem with clicks and
590 voice starvation for some gigs)
591 - playback is no longer disabled during instrument loading
592 - all notes playing on a channel that changes its instrument keep
593 playing with the old instrument until they get a note off
594 command
595 - EG fix: a release value of zero could cause noises or crash
596 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
597 - EG fine tuning: when attack is zero the EG starts at a level
598 above max sustain level, which means that there is a decay phase
599 even if sustain is 100%
600 - more EG fixes: the level could sometimes go below zero and cause
601 noises or crashes
602 - minor fix of EGDecay (patch by Toshi Nagata)
603 - fixed compiler error when --enable-override-filter-type was
604 supplied to the configure script (fixes #46)
605 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
606 instead of a fix value
607 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
608 127 (solo mode) only kill voices if the respective mode really
609 changed
610
611 * LSCP server:
612 - fixed compile time error for old Bison versions
613 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
614 - parser now supports extended ASCII character set
615 (up to ASCII code 255, i.e. includes now umlauts and accents)
616 - filename arguments in LSCP commands now allow to use escape
617 sequences, that is directly literal as one of: \', \", \\, \n, \r,
618 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
619 code value like \xf2) (fixes bug #24)
620 - the following LSCP commands now also support escape sequences for at
621 least one of their text-based parameters (i.e. name, description):
622 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
623 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
624 "SET DB_INSTRUMENT_DIRECTORY NAME",
625 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
626 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
627 "FIND DB_INSTRUMENT_DIRECTORIES"
628 - returns verbose syntax errors (line and column where syntax error
629 occured, the unexpected character and the actually expected, possible
630 character(s), the latter only if less than 5 possibilities)
631 - made sure that LSCP syntax is not affected by gigedit locale
632 settings
633 - bugfix regarding strings parameter lists: all comma separated lists
634 of strings were treated as being one string containing commas
635 (fixes #57)
636
637 * Bug fixes:
638 - fixed crash occurring on certain LSCP scripts (Bug 39)
639 - another thread safety fix for lscp "load engine" and "set
640 channel audio output device"
641 - fixed a crash which occurs when reassigning the same engine
642 on a sampler channel with connected MIDI device
643 - fixed a crash which occurs when changing the number of ports of a MIDI
644 device connected to a sampler channel to number less then or equal
645 to the index of the port to which the sampler channel is connected.
646 - The previous bindings were not been disconnected when altering
647 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
648 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
649 - The active stream/voice count statistic was incorrect.
650 - notification events were not been sent for some sampler
651 channel changes
652 - added default min and max values to restrict the number of allowed
653 audio output channels and MIDI input ports
654 - the connection to the PCM interface is now closed when destroying
655 an audio output device
656 - files with slash in their path or filename could not be loaded
657
658 * test cases:
659 - updated and fixed (haven't been touched in a while)
660
661 Version 0.4.0 (24 November 2006)
662
663 * packaging changes:
664 - changed deprecated copyright attribute to license; added ldconfig
665 to post-(un)install steps; added devel package for liblinuxsampler;
666 to linuxsampler.spec (RPM)
667 - install necessary development header files for allowing 3rd party
668 applications to link against liblinuxsampler
669 - liblinuxsampler's API documentation can be generated with 'make docs'
670 (Doxygen required)
671 - added benchmark to automatically detect the best triangle LFO
672 implementation (currently either an integer math solution or a
673 di-harmonic approximation), automatic detection can be overriden
674 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
675 configure script argument though (mandatory for cross-compilation)
676 - do not automatically pick optimized gcc flags if the user already
677 provided some on his own (as CXXFLAGS)
678 - added compile time option to disable processing of All-Notes-Off MIDI
679 messages
680 - added compile time options to allow disabling the various audio and
681 MIDI drivers
682 - fixed automatic GCC CPU switch detection on PPC
683 (patch by Ebrahim Mayat)
684
685 * Gigasampler format engine:
686 - extensive synthesis optimization
687 (reimplementation of EGs and LFO(s), removed synthesis parameter
688 prerendering and the synthesis parameter matrix in general, splitting
689 each audio fragment into subfragments now where each subfragment uses
690 constant pitch and filter coefficients. The volume coefficient is
691 linearly interpolated inside a subfragment, unless
692 --disable-interpolate-volume is set.)
693 - fine tuning of the EG modulation parameters
694 - improved filter cutoff calculation by adding support for the
695 following gig parameters: Cutoff freq (used when no cutoff
696 controller is defined), Control invert, Minimum cutoff, Velocity
697 curve and Velocity range. The keyboard tracking now scales
698 cutoff frequency instead of resonance.
699 - added support for gig parameter Resonance.
700 - fixed bug in sysex handling (patch by Juan Linietsky)
701 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
702 which can be overridden with --enable-global-attenuation
703 - EG fixes: made the length of "attack hold" stage more
704 accurate. Release stage can now start before attack stage
705 ends. Cancel release didn't work when sustain was zero. Attack
706 time now has a minimal value to prevent clicks.
707 - fixed pitch changes larger than one octave
708 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
709 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
710 all modes can be altered via standard GM messages, that is CC5 for
711 altering portamento time, CC65 for enabling / disabling portamento
712 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
713 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
714 parameter) and crossfade
715 - added support for the "attenuation controller threshold" gig
716 parameter
717 - added smoothing of volume changes caused by control change
718 messages
719 - sample loop parameters are now taken from the DimensionRegion
720 instead of the wave chunk
721 - fixed keyswitching for v3 gigs with a number of keyswitch splits
722 not equal to a power of two
723 - reimplementation of the filter algorithm. The new filter is more
724 accurate and supports all gig filter types, including bandreject
725 and lowpass turbo.
726 - real support for 24 bit samples - samples are not truncated to
727 16 bits anymore
728 - support for aftertouch (channel pressure, not polyphonic
729 aftertouch)
730 - LFO1 behaviour fixed (dampening from max volume instead of
731 amplifying from 0)
732
733 * LSCP server:
734 - fixed application exit on broken pipe error (fixes bug #20)
735 - fixed the notification messages delay due to lack of
736 network activity (fixes bug #26)
737 - fixed parser bug which occured on space(s) within device parameters
738 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
739
740 * audio driver:
741 - added aRts audio output driver (by no means RT safe)
742
743 * MIDI driver:
744 - fixed legacy sysex code which caused dispatching of MIDI SysEx
745 messages several times instead of once
746 - API extension for MIDI drivers which already supply exact time stamps
747 for events (i.e. for offline rendering based MIDI drivers)
748 - added checks for bad MIDI data
749
750 * linuxsampler application:
751 - show available sampler engine types on startup
752
753 * general changes:
754 - support for muting sampler channels and solo mode of the same, two new
755 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
756 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
757 introduced for this, the behavior is the same like on a mixer console
758 (patch by Grigor Iliev, a bit adjusted). Also added configure option
759 --enable-process-muted-channels which can be used to enable the
760 processing of muted channels.
761 - support for sostenuto pedal
762 - support for monitoring the total number of active voices
763 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
764 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
765 - fixed some memory management errors
766 - fixed some concurrency problems that could lead to crashes when
767 LSCP commands were executed
768 - fixed crash when instrument loading failed previously on the same
769 sampler channel (fixes bug #36)
770
771 Version 0.3.3 (15 July 2005)
772
773 * packaging changes:
774 - fixed compilation with gcc 4.0
775
776 * Gigasampler format engine:
777 - LFO preprocessing was performed even though the respective LFO was
778 disabled by the instrument patch (minor efficiency fix)
779 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
780 for volume ramp downs in the same fragment (needed for current voice
781 stealing implementation) then simply inform the user with a warning
782 about possible click sounds and reduce the volume ramp down
783 appropriately instead of cancelling the audio device connection
784
785 Version 0.3.2 (24 June 2005)
786
787 * packaging changes:
788 - updated autotools build files to compile on OS X
789 (conditional compilation of CoreMIDI and MidiShare drivers)
790 - hand-crafted assembly optimization code can be disabled with
791 './configure --disable-asm' (definitely not recommended)
792 - fixed 'make dist' rule to include all necessary files
793 - require automake (>= 1.5) for 'make -f Makefile.cvs'
794 (due to 'dist-bzip2' automake option)
795
796 * Gigasampler format engine:
797 - support for the gig parameters for "release velocity response" curves
798 - fine tuning of the EGADSR envelope
799 - volume of release triggered samples now depends on note-on velocity,
800 note length and gig parameter "release trigger decay" instead of
801 note-off velocity.
802 - revised voice stealing
803 (fixes crash and endless loop caused by voice stealing)
804 - don't reset scale tuning on instrument or audio output device change
805 - handle key group conflicts right at the beginning of each fragment
806 instead of when the respective voice is actually launched
807 (fixes undefined behavior if stolen voices belonged to a key group -
808 this case was followed by a "killed voice survived" error message)
809 - fixed minor issue with null/silence samples
810 (those stole voices even though they don't need a voice at all which
811 resulted in "voice stealing didn't work out" messages)
812 - don't reset volume, pan, pitch and MIDI controller values on
813 instrument or audio output device change
814
815 * LSCP server:
816 - fixed some crashes (patch by Grigor Iliev, fixes #19)
817 - fixed LSCP event "CHANNEL_INFO" notification
818 (e.g. did not notify on volume changes or MIDI program change events)
819
820 * linuxsampler application:
821 - added command line parameters --lscp-addr and --lscp-port to override
822 default IP address and port of LSCP server
823
824 Version 0.3.1 (24 May 2005)
825
826 * initial release
