* sfz engine: implemented opcode end

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)
41 - implemented support for internal LADSPA effects
42 - raised limit of program change queue from 100 to 512
43 (as suggested by Alex Stone)

160 stereo
161 - VST: made it possible to build the VST plugin for Mac
162 - AU: link AU plugin dynamically if --disable-shared isn't
163 specified
164
165 * MIDI driver:
166 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
167 the ALSA sequencer client name
168 - removed limit of maximum amount of MIDI ports per MIDI device, since
169 there is no reason for this limit
170

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

228 after MIDI/audio device creation failure
229
230 Version 1.0.0 (31 July 2009)
231
232 * packaging changes:
233 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
234 causing e.g. the libgig test to fail when
235 "./configure --disable-jack-driver" was used
236 (patch by Alexis Ballier)
237 - fixed compilation with gcc 4.3
238 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
239 - fixed configure so it detects x86_64 (#107)
240 - fixes for building with newer MinGW versions
241 - fix for building with bison 2.4 (#111)
242 - fixed building with libgig installed in a non-standard directory
243 - minor fix in configure for mmsystem.h detection on MinGW
244 - Windows: look for editor plugins and Fantasia using base
245 directory of liblinuxsampler dll (look in the same directory and one
246 directory above)
247 - configure script fix: removed unconditional use of SSE
248 - fixed building with sqlite installed in a non-standard directory
249 - when cross-compiling, don't try to create instruments.db
250 - fix for new mingw-w64 version, which has usleep
251
252 * general changes:
253 - bugfix: on some POSIX systems instrument editor plugins refused to
254 load as we used a non-portable Linux specific struct field
255 (fixes bug #70, patch by Ronald Baljeu)
256 - fixed endless loop which occured when loading an instrument editor
257 plugin DLL on Windows systems failed
258 - fixed memory leaks that occurred when liblinuxsampler was unloaded
259 - optimized the SynchronizedConfig class so it doesn't wait
260 unnecessarily long after an update
261 - added support for notifying instrument editors on note-on / note-off
262 events (e.g. to highlight the pressed keys on the virtual keyboard
263 of gigedit)
264 - added support for triggering notes by instrument editors (see above)
265 - be verbose on DLL load errors (on Linux)
266 - fixed di-harmonic triangle LFO implementation (this LFO implementation
267 is only used by very few systems, most pick the int math
268 implementation, which is usually faster)
269 - fixes for audio drivers with varying buffer sizes
270 - experimental support for running LinuxSampler as a DSSI, LV2 and
271 VST plugin
272 - notification events for stream/voice count statistics are now sent
273 only when there are actual changes
274 - added memory ordering constraints to improve stability on
275 multi-core and multi-cpu systems
276 - maximum voices and disk streams can now be altered at runtime
277 - fixed CPU feature detection on x86_64 (maybe fixes #108)
278 - automatic stacktrace mechanism is now turned off by default and can
279 be switched on by command line option "--stacktrace" (the automatic
280 stacktrace mechanism seems to be broken on most systems at the moment)
281 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
282 a pointer to the launched InstrumentEditor object
283 - added optional 3rd party user data parameter for following
284 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
285 InstrumentEditor::Launch(),
286 InstrumentManager::LaunchInstrumentEditor()
287 - theoretical fix: made SynchronizedConfig follow C++0x memory
288 model more strictly
289 - fixes for using large audio device buffers
290 - Windows: add the installation directory to the DLL search path
291 when loading an editor plugin (solves problems with VST and
292 gigedit on systems with other GTK versions installed)
293
294 * audio driver:
295 - removed the nonsense audio channel constraint (which was hard coded to
296 max. 100 audio channels) for most audio drivers
297 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
298 opposed to the LSCP specs
299 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
300 reflected the wrong value
301 - fixed a memory management bug in ASIO driver
302 - Makefile fix: JACK_CFLAGS wasn't used
303 - JACK: use jack_client_open instead of the deprecated
304 jack_client_new
305 - added (experimental) CoreAudio driver
306 - applied old fixes to the ASIO driver that were included in the
307 previous binary release but accidentally never committed to CVS
308 (fixes #117)
309 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
310 win64)
311 - VST: added support for sample rate and buffer size changes
312 - VST: close editor (Fantasia) when the VST is removed
313 - VST: avoid opening Fantasia more than once for each VST instance
314 - VST: export main function as "main" on Linux too (fix for
315 energyXT)
316 - VST: changed number of output channels from one stereo to 16
317 stereo
318 - added channel routing, fxsends and midi maps to the settings
319 stored in the plugin state
320 - performance optimization of AudioChannel::MixTo() and
321 AudioChannel::CopyTo() methods using GCC vector exensions
322 (if available)
323 - ASIO fixes: avoid initializing the device twice, avoid throwing
324 exception when getting parameters from a disconnected device
325
326 * MIDI driver:
327 - added JACK MIDI driver
328 - dispatch bank select as ordinary CC as well, the user might seriously
329 want to (mis)use it for some purpose ("fixed" in all current MIDI
330 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
331 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
332 CoreMidi or AU
333 - fixed mingw-w64 compilation error in MME driver
334 - made program change handling in MIDI thread real-time safe by
335 moving the logic to a non-RT thread
336 - fixed minor memory leak in ALSA driver
337
338 * instruments database:
339 - avoid time consuming samples scanning when adding instruments
340 to the instruments database
341 - added support for handling lost files in the instruments database
342 - Implemented option for adding instruments in separate directories
343 in the instruments database
344 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
345 - work-around for missing fnmatch function on Windows to make
346 instrument database compilable
347 - added instrument database support on Windows
348 works with both standalone mode and VST plugin.
349 the instruments DB file is located in
350 %USERPROFILE%\.linuxsampler\instruments.db which allows different
351 databases for each windows user
352 if no DB is present it automatically creates the .linuxsampler subdir
353 and then creates an empty DB
354 - fixed recursive import, which was broken on Windows
355
356 * Gigasampler format engine:
357 - fixed a memory leak that could happen when a channel was deleted
358 while notes were playing
359 - made it possible to load an instrument even if the audio thread
360 isn't running
361 - added partial support for the "Controller Triggered" MIDI rule,
362 enough for piano gigs with pedal noise samples
363 - minor fix: only mark FX sends as being modified if really the
364 respective FX send MIDI controller was used
365 - added support for GM global device volume SysEx message
366 (can be selected at compile time to either apply globally to the
367 whole sampler [default] or only to the sampler channels that are
368 connected to the respective MIDI input port the SysEx message arrived
369 on)
370 - bugfix: notes triggered at position 0 in the audio buffer were
371 sometimes wrongly killed in the same buffer, causing no sound to
372 be played
373 - added support for chromatic / drumkit mode Roland GS Sysex message
374 which is usally used to switch a part between chromatic sounds and
375 drumkit sounds (as opposed to their common default setting of MIDI
376 part 10 being a drumkit part and all other ones chromatic parts), in
377 LS however one can switch between the first 16 MIDI instrument maps
378 defined for the sampler
379 - made it possible to create multiple sample channels even if the
380 audio thread isn't running
381 - fixed crash when removing channel with active voices (#116)
382 - bugfix: on sample reference changes (instrument editor), only
383 un-cache the respective sample if it's really not used by any
384 sampler engine anymore
385 - re-cache samples in case they were changed by an instrument editor,
386 e.g. when a sample was added while playing (#82)
387 - fixed hanging notes which occured when note-off event had the exact
388 same time stamp as the voice's note-on event and occured both in the
389 same audio fragment cycle (fixes bug #112)
390 - added support for the "fine tune" and "pitch bend range"
391 instrument-level gig parameters
392 - fixed minor artifacts in pitch bend handling
393 - added support for GS Reset SysEx message
394 - allow gig files to use unlimited downward pitch shifting
395 - added a limit check for upward pitch shifting
396 - bugfix: sometimes, when playing a note twice fast, the second
397 note was silent
398 - fixed crash happening when a pitch bend event arrived at the
399 same time a new instrument was loading
400
401 * LSCP server:
402 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
403 react on MIDI data arriving on certain sampler channels (so far only
404 Note-On and Note-Off events are sent via this LSCP event)
405 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
406 react on MIDI data arriving on certain MIDI input devices (so far only
407 Note-On and Note-Off events are sent via this LSCP event)
408 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
409 SET DB_INSTRUMENT FILE_PATH
410 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
411 frontends to send MIDI messages to specific sampler channel
412 - added two additional fields to GET FILE INSTRUMENT INFO command -
413 KEY_BINDINGS and KEYSWITCH_BINDINGS
414 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
415 was incorrect
416 - Optimized the retrieval of the MIDI instrument mappings
417 - added new LSCP command "SET VOICES" to globally alter the maximum
418 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
419 be triggered respectively
420 - added new LSCP command "SET STREAMS" to globally alter the maximum
421 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
422 which will be triggered respectively
423 - bugfix: retry if "select" returns EINTR (this fixes a crash when
424 a gigedit file dialog is opened)
425 - close all connections when LSCPServer is deleted
426 - hard close of all sockets on exit
427 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
428 driver
429
430 * Bug fixes:
431 - fixed a crash which occurs when removing a sampler channel waiting
432 to start instrument loading after another channel
433 - fixed a crash which occurs when removing a sampler channel with
434 instrument loading in progress (bug #113)
435 - fixed termination caused by uncaught exception when adding MIDI
436 instrument with PERSISTENT load mode
437 - fixed possible iterator invalidations when resetting the sampler
438 - fixed memory leaks when issuing the following LSCP commands:
439 GET AUDIO_OUTPUT_DRIVER INFO
440 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
441 GET MIDI_INPUT_DRIVER INFO
442 GET MIDI_INPUT_DRIVER_PARAMETER INFO
443 - fixed possible compilation error when sqlite is not present
444 - fixed orphaned pointers when setting maximum voices limit (bug #118)
445 - fixed crash when changing the audio output device of a sampler
446 channel with loaded instrument and start playing notes
447 - fixed endless loop in Engine::SuspendAll() (bug #120)
448 - fixed a low-level atomic load function that was broken on 64-bit
449 PowerPC, which probably could cause crashes on that platform
450 - fixed a memory management error which could cause a crash when a
451 plugin was unloaded
452 - bugfix: two private structs had the same name, which could cause
453 problems if the linker chose the wrong constructor
454 - fixed low-level ConditionServer usage bug that caused lockups on
455 Windows
456
457
458 Version 0.5.1 (6 December 2007)
459
460 * packaging changes:
461 - added autoconf checks for pthread library
462 - added autoconf check for pthread bug found on certain NPTL-enabled
463 glibc versions (see Gentoo bug report #194076)
464 - added autoconf checks for MS Windows
465
466 * general changes:
467 - bugfix: the thread used by an editor plugin didn't die when the
468 editor closed
469 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
470 out all the space. operator--() did not apply size_mask after
471 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
472 order to avoid problems with the _NonVolatileReader functions.
473 - bugfix: Stream.h: added a missing divide by BytesPerSample in
474 GetWriteSpace(). Since this function is currently only used in
475 the stream's qsort() compare function, it didn't trigger any
476 bugs.
477 - Resampler.h, Synthesizer.h: cubic interpolation now works in
478 24bit mode too. Faster method to read 24bit words on little
479 endian machines (x86): replaced 3 byte reads + shifts with a 1
480 unaligned 32bit read and shift
481 - experimental support for MS Windows (MIDI input via MME, AUDIO
482 output via ASIO)
483 - made handling of SIGINT signal (Ctrl-C) a bit more robust
484 - support for monitoring the total number of active disk streams
485 (new LSCP commands: GET TOTAL_STREAM_COUNT,
486 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
487
488 * AUDIO driver:
489 - added Windows ASIO low latency audio driver
490
491 * MIDI driver:
492 - added MME Windows MIDI driver
493
494 * LSCP server:
495 - added support for Windows style path / filenames, however with
496 forward slash path separators instead of backslash
497 (i.e. "C:/foo/bar.gig")
498 - allow naughty liblscp to send non-string device parameters within
499 apostrophes as well
500 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
501 "LIST FILE INSTRUMENTS <file>" and
502 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
503 about an arbitrary instrument file on the system where the sampler is
504 running on
505
506 Version 0.5.0 (15 October 2007)
507
508 * packaging changes:
509 - config.h is not going to be installed along with liblinuxsampler's
510 API header files anymore
511 - only the API relevant header (and source) files will be exported to
512 the Doxygen API documentation (explicitly listed in Doxyfile.in)
513 - added completely new XCode project files for Mac OSX which is now
514 capable to execute our autoconf environment, thus no need anymore
515 to maintain the compile time configuration file (osx/version.h) for
516 OSX manually (patch by Toshi Nagata)
517 - fixed buggy boolean --enable-foo / --disable-foo configure script
518 parameters
519 - global.h now only covers global definitions that are needed for the
520 C++ API header files, all implementation internal global definitions
521 are now in global_private.h
522 - atomic.h is not exposed to the C++ API anymore
523 - no need to include config.h anymore for using LS's API header files
524 - fixed warnings in API doc generation
525
526 * general changes:
527 - replaced the old, confusing MIDI program change mechanism by a
528 flexible MIDI instrument mapper which allows to map arbitrary
529 (MIDI bank, MIDI program) pairs with arbitrary
530 (engine type, instrument file, file index) triplets which will be
531 loaded on the respective channel when such MIDI program change
532 messages arrive, beside that, each entry allows to define a life-time
533 strategy for the instrument, so the user can define whether the
534 instrument should i.e. be permanently loaded (to be able to switch
535 quickly among sounds) or i.e. loaded just on demand when the
536 respective program change arrives (to safe RAM space), as well as a
537 global volume factor for each entry, so the user can adjust the volume
538 dynamic of his mapped instrument collection without having to modify
539 the instrument files, also one can manage arbitrary amount of such
540 MIDI instrument maps and assign each sampler channel individually
541 a certain map, so that i.e. separation of normal instruments and
542 drumkits is possible
543 - new notification events for tracking changes to audio/MIDI devices,
544 MIDI instrument maps, MIDI instruments, FX sends, global volume.
545 - sampler was limited to load max. 200 instruments in the background
546 due to a constant size RingBuffer FIFO which is now replaced by a
547 dynamic (unlimited) size std::list FIFO
548 - added FX sends, these allow to route audio signals to arbitrary audio
549 output channels for being processed by external effect processors
550 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
551 controllers
552 - global (sampler wide) volume can now be controlled at runtime
553 - Implemented new, improved notification system
554 - fixed compilation errors regarding OSX
555 (patch by Toshi Nagata)
556 - implemented instruments database
557 - added support for escape sequences to the instruments database
558 - added highly experimental support for on-the-fly instrument editing
559 within the sampler's process (by using instrument editor plugins),
560 you'll notice the new "Registered instrument editors:" message on
561 startup, added a new LSCP command:
562 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
563 to spawn a matching instrument editor for the instrument on the
564 given sampler channel, the plugin path can be overridden at compile
565 time with ./configure --enable-plugin-dir=/some/dir
566 - added experimental code for synchronizing instrument editors hosted
567 in the sampler's process to safely edit instruments while playing
568 without a crash (hopefully) by either suspending single regions
569 wherever possible or if unavoidable whole engine(s)
570 - fixed several issues in fundamental "Thread" class: set scheduling
571 policy and priority on thread level, set a minimum stack size for
572 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
573 threads simply inherited properties of starting thread instead of
574 setting their own policy and priority
575 - minor fix in our automatic stack trace mechanism on crashes, the
576 main process did not wait for the stack trace process to finish
577 its output
578 - fixed some minor memory leaks
579 - reenabled assembly features support, at the moment only for
580 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
581 - minor assembly fix in x86 features detection (don't use the PIC
582 register, to avoid relocations in the text segment at runtime)
583 - POSIX callback functions of Thread.h are hidden
584
585 * MIDI driver:
586 - dispatch bank select (MSB and LSB) messages
587
588 * audio driver:
589 - the ALSA audio output driver parameters now reflect the correct
590 parameter value ranges for the respective selected sound card
591 (patch by Till Wimmer, a bit fixed and extended)
592
593 * Gigasampler format engine:
594 - if a filter is used and EG2 finishes before EG1, let the voice
595 die when EG2 has finished (this fixes a problem with clicks and
596 voice starvation for some gigs)
597 - playback is no longer disabled during instrument loading
598 - all notes playing on a channel that changes its instrument keep
599 playing with the old instrument until they get a note off
600 command
601 - EG fix: a release value of zero could cause noises or crash
602 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
603 - EG fine tuning: when attack is zero the EG starts at a level
604 above max sustain level, which means that there is a decay phase
605 even if sustain is 100%
606 - more EG fixes: the level could sometimes go below zero and cause
607 noises or crashes
608 - minor fix of EGDecay (patch by Toshi Nagata)
609 - fixed compiler error when --enable-override-filter-type was
610 supplied to the configure script (fixes #46)
611 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
612 instead of a fix value
613 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
614 127 (solo mode) only kill voices if the respective mode really
615 changed
616
617 * LSCP server:
618 - fixed compile time error for old Bison versions
619 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
620 - parser now supports extended ASCII character set
621 (up to ASCII code 255, i.e. includes now umlauts and accents)
622 - filename arguments in LSCP commands now allow to use escape
623 sequences, that is directly literal as one of: \', \", \\, \n, \r,
624 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
625 code value like \xf2) (fixes bug #24)
626 - the following LSCP commands now also support escape sequences for at
627 least one of their text-based parameters (i.e. name, description):
628 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
629 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
630 "SET DB_INSTRUMENT_DIRECTORY NAME",
631 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
632 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
633 "FIND DB_INSTRUMENT_DIRECTORIES"
634 - returns verbose syntax errors (line and column where syntax error
635 occured, the unexpected character and the actually expected, possible
636 character(s), the latter only if less than 5 possibilities)
637 - made sure that LSCP syntax is not affected by gigedit locale
638 settings
639 - bugfix regarding strings parameter lists: all comma separated lists
640 of strings were treated as being one string containing commas
641 (fixes #57)
642
643 * Bug fixes:
644 - fixed crash occurring on certain LSCP scripts (Bug 39)
645 - another thread safety fix for lscp "load engine" and "set
646 channel audio output device"
647 - fixed a crash which occurs when reassigning the same engine
648 on a sampler channel with connected MIDI device
649 - fixed a crash which occurs when changing the number of ports of a MIDI
650 device connected to a sampler channel to number less then or equal
651 to the index of the port to which the sampler channel is connected.
652 - The previous bindings were not been disconnected when altering
653 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
654 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
655 - The active stream/voice count statistic was incorrect.
656 - notification events were not been sent for some sampler
657 channel changes
658 - added default min and max values to restrict the number of allowed
659 audio output channels and MIDI input ports
660 - the connection to the PCM interface is now closed when destroying
661 an audio output device
662 - files with slash in their path or filename could not be loaded
663
664 * test cases:
665 - updated and fixed (haven't been touched in a while)
666
667 Version 0.4.0 (24 November 2006)
668
669 * packaging changes:
670 - changed deprecated copyright attribute to license; added ldconfig
671 to post-(un)install steps; added devel package for liblinuxsampler;
672 to linuxsampler.spec (RPM)
673 - install necessary development header files for allowing 3rd party
674 applications to link against liblinuxsampler
675 - liblinuxsampler's API documentation can be generated with 'make docs'
676 (Doxygen required)
677 - added benchmark to automatically detect the best triangle LFO
678 implementation (currently either an integer math solution or a
679 di-harmonic approximation), automatic detection can be overriden
680 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
681 configure script argument though (mandatory for cross-compilation)
682 - do not automatically pick optimized gcc flags if the user already
683 provided some on his own (as CXXFLAGS)
684 - added compile time option to disable processing of All-Notes-Off MIDI
685 messages
686 - added compile time options to allow disabling the various audio and
687 MIDI drivers
688 - fixed automatic GCC CPU switch detection on PPC
689 (patch by Ebrahim Mayat)
690
691 * Gigasampler format engine:
692 - extensive synthesis optimization
693 (reimplementation of EGs and LFO(s), removed synthesis parameter
694 prerendering and the synthesis parameter matrix in general, splitting
695 each audio fragment into subfragments now where each subfragment uses
696 constant pitch and filter coefficients. The volume coefficient is
697 linearly interpolated inside a subfragment, unless
698 --disable-interpolate-volume is set.)
699 - fine tuning of the EG modulation parameters
700 - improved filter cutoff calculation by adding support for the
701 following gig parameters: Cutoff freq (used when no cutoff
702 controller is defined), Control invert, Minimum cutoff, Velocity
703 curve and Velocity range. The keyboard tracking now scales
704 cutoff frequency instead of resonance.
705 - added support for gig parameter Resonance.
706 - fixed bug in sysex handling (patch by Juan Linietsky)
707 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
708 which can be overridden with --enable-global-attenuation
709 - EG fixes: made the length of "attack hold" stage more
710 accurate. Release stage can now start before attack stage
711 ends. Cancel release didn't work when sustain was zero. Attack
712 time now has a minimal value to prevent clicks.
713 - fixed pitch changes larger than one octave
714 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
715 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
716 all modes can be altered via standard GM messages, that is CC5 for
717 altering portamento time, CC65 for enabling / disabling portamento
718 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
719 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
720 parameter) and crossfade
721 - added support for the "attenuation controller threshold" gig
722 parameter
723 - added smoothing of volume changes caused by control change
724 messages
725 - sample loop parameters are now taken from the DimensionRegion
726 instead of the wave chunk
727 - fixed keyswitching for v3 gigs with a number of keyswitch splits
728 not equal to a power of two
729 - reimplementation of the filter algorithm. The new filter is more
730 accurate and supports all gig filter types, including bandreject
731 and lowpass turbo.
732 - real support for 24 bit samples - samples are not truncated to
733 16 bits anymore
734 - support for aftertouch (channel pressure, not polyphonic
735 aftertouch)
736 - LFO1 behaviour fixed (dampening from max volume instead of
737 amplifying from 0)
738
739 * LSCP server:
740 - fixed application exit on broken pipe error (fixes bug #20)
741 - fixed the notification messages delay due to lack of
742 network activity (fixes bug #26)
743 - fixed parser bug which occured on space(s) within device parameters
744 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
745
746 * audio driver:
747 - added aRts audio output driver (by no means RT safe)
748
749 * MIDI driver:
750 - fixed legacy sysex code which caused dispatching of MIDI SysEx
751 messages several times instead of once
752 - API extension for MIDI drivers which already supply exact time stamps
753 for events (i.e. for offline rendering based MIDI drivers)
754 - added checks for bad MIDI data
755
756 * linuxsampler application:
757 - show available sampler engine types on startup
758
759 * general changes:
760 - support for muting sampler channels and solo mode of the same, two new
761 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
762 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
763 introduced for this, the behavior is the same like on a mixer console
764 (patch by Grigor Iliev, a bit adjusted). Also added configure option
765 --enable-process-muted-channels which can be used to enable the
766 processing of muted channels.
767 - support for sostenuto pedal
768 - support for monitoring the total number of active voices
769 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
770 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
771 - fixed some memory management errors
772 - fixed some concurrency problems that could lead to crashes when
773 LSCP commands were executed
774 - fixed crash when instrument loading failed previously on the same
775 sampler channel (fixes bug #36)
776
777 Version 0.3.3 (15 July 2005)
778
779 * packaging changes:
780 - fixed compilation with gcc 4.0
781
782 * Gigasampler format engine:
783 - LFO preprocessing was performed even though the respective LFO was
784 disabled by the instrument patch (minor efficiency fix)
785 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
786 for volume ramp downs in the same fragment (needed for current voice
787 stealing implementation) then simply inform the user with a warning
788 about possible click sounds and reduce the volume ramp down
789 appropriately instead of cancelling the audio device connection
790
791 Version 0.3.2 (24 June 2005)
792
793 * packaging changes:
794 - updated autotools build files to compile on OS X
795 (conditional compilation of CoreMIDI and MidiShare drivers)
796 - hand-crafted assembly optimization code can be disabled with
797 './configure --disable-asm' (definitely not recommended)
798 - fixed 'make dist' rule to include all necessary files
799 - require automake (>= 1.5) for 'make -f Makefile.cvs'
800 (due to 'dist-bzip2' automake option)
801
802 * Gigasampler format engine:
803 - support for the gig parameters for "release velocity response" curves
804 - fine tuning of the EGADSR envelope
805 - volume of release triggered samples now depends on note-on velocity,
806 note length and gig parameter "release trigger decay" instead of
807 note-off velocity.
808 - revised voice stealing
809 (fixes crash and endless loop caused by voice stealing)
810 - don't reset scale tuning on instrument or audio output device change
811 - handle key group conflicts right at the beginning of each fragment
812 instead of when the respective voice is actually launched
813 (fixes undefined behavior if stolen voices belonged to a key group -
814 this case was followed by a "killed voice survived" error message)
815 - fixed minor issue with null/silence samples
816 (those stole voices even though they don't need a voice at all which
817 resulted in "voice stealing didn't work out" messages)
818 - don't reset volume, pan, pitch and MIDI controller values on
819 instrument or audio output device change
820
821 * LSCP server:
822 - fixed some crashes (patch by Grigor Iliev, fixes #19)
823 - fixed LSCP event "CHANNEL_INFO" notification
824 (e.g. did not notify on volume changes or MIDI program change events)
825
826 * linuxsampler application:
827 - added command line parameters --lscp-addr and --lscp-port to override
828 default IP address and port of LSCP server
829
830 Version 0.3.1 (24 May 2005)
831
832 * initial release
