* fixed handling of rapid bank select and program change messages sent
  to the same sampler channel (patch from the Open Octave project,
  slightly adjusted)

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)
44 - implemented sine LFO, pulse LFO and saw LFO

253 channel to a different engine type
254 - fixed crash when deleting a sampler channel or changing engine
255 type while an instrument load was in progress
256 - bugfix: playing a note while changing the instrument could cause
257 a crash, or give "Handing back unknown region" error messages
258 - bugfix: calling SET VOICES (which Fantasia does on start and
259 refresh) could cause instruments to be unloaded
260 - Mac OS X: fixed name collision of enum in EffectControl and
261 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
262 - Mac OS X: fixed hanging threads
263 - Windows: disabled the previous thread fix on non-Mac systems, as
264 it caused hanging threads on Windows
265 - Fixed possible crashes due to corrupted MIDI/audio device list
266 after MIDI/audio device creation failure
267 - When creating MIDI instrument map entries with "PERSISTENT" type, the
268 instruments were uselessly precached with zero samples, however it still
269 took the full preloading time and on 1st program change the respective
270 instrument was completely reloaded again.
271 - fixed handling of rapid bank select and program change messages
272 sent to the same sampler channel (patch from the Open Octave
273 project, slightly adjusted)
274
275 Version 1.0.0 (31 July 2009)
276
277 * packaging changes:
278 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
279 causing e.g. the libgig test to fail when
280 "./configure --disable-jack-driver" was used
281 (patch by Alexis Ballier)
282 - fixed compilation with gcc 4.3
283 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)

285 - fixes for building with newer MinGW versions
286 - fix for building with bison 2.4 (#111)
287 - fixed building with libgig installed in a non-standard directory
288 - minor fix in configure for mmsystem.h detection on MinGW
289 - Windows: look for editor plugins and Fantasia using base
290 directory of liblinuxsampler dll (look in the same directory and one
291 directory above)
292 - configure script fix: removed unconditional use of SSE
293 - fixed building with sqlite installed in a non-standard directory
294 - when cross-compiling, don't try to create instruments.db
295 - fix for new mingw-w64 version, which has usleep
296
297 * general changes:
298 - bugfix: on some POSIX systems instrument editor plugins refused to
299 load as we used a non-portable Linux specific struct field
300 (fixes bug #70, patch by Ronald Baljeu)
301 - fixed endless loop which occured when loading an instrument editor
302 plugin DLL on Windows systems failed
303 - fixed memory leaks that occurred when liblinuxsampler was unloaded
304 - optimized the SynchronizedConfig class so it doesn't wait
305 unnecessarily long after an update
306 - added support for notifying instrument editors on note-on / note-off
307 events (e.g. to highlight the pressed keys on the virtual keyboard
308 of gigedit)
309 - added support for triggering notes by instrument editors (see above)
310 - be verbose on DLL load errors (on Linux)
311 - fixed di-harmonic triangle LFO implementation (this LFO implementation
312 is only used by very few systems, most pick the int math
313 implementation, which is usually faster)
314 - fixes for audio drivers with varying buffer sizes
315 - experimental support for running LinuxSampler as a DSSI, LV2 and
316 VST plugin
317 - notification events for stream/voice count statistics are now sent
318 only when there are actual changes
319 - added memory ordering constraints to improve stability on
320 multi-core and multi-cpu systems
321 - maximum voices and disk streams can now be altered at runtime
322 - fixed CPU feature detection on x86_64 (maybe fixes #108)
323 - automatic stacktrace mechanism is now turned off by default and can
324 be switched on by command line option "--stacktrace" (the automatic
325 stacktrace mechanism seems to be broken on most systems at the moment)
326 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
327 a pointer to the launched InstrumentEditor object
328 - added optional 3rd party user data parameter for following
329 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
330 InstrumentEditor::Launch(),
331 InstrumentManager::LaunchInstrumentEditor()
332 - theoretical fix: made SynchronizedConfig follow C++0x memory
333 model more strictly
334 - fixes for using large audio device buffers
335 - Windows: add the installation directory to the DLL search path
336 when loading an editor plugin (solves problems with VST and
337 gigedit on systems with other GTK versions installed)
338
339 * audio driver:
340 - removed the nonsense audio channel constraint (which was hard coded to
341 max. 100 audio channels) for most audio drivers
342 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
343 opposed to the LSCP specs
344 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
345 reflected the wrong value
346 - fixed a memory management bug in ASIO driver
347 - Makefile fix: JACK_CFLAGS wasn't used
348 - JACK: use jack_client_open instead of the deprecated
349 jack_client_new
350 - added (experimental) CoreAudio driver
351 - applied old fixes to the ASIO driver that were included in the
352 previous binary release but accidentally never committed to CVS
353 (fixes #117)
354 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
355 win64)
356 - VST: added support for sample rate and buffer size changes
357 - VST: close editor (Fantasia) when the VST is removed
358 - VST: avoid opening Fantasia more than once for each VST instance
359 - VST: export main function as "main" on Linux too (fix for
360 energyXT)
361 - VST: changed number of output channels from one stereo to 16
362 stereo
363 - added channel routing, fxsends and midi maps to the settings
364 stored in the plugin state
365 - performance optimization of AudioChannel::MixTo() and
366 AudioChannel::CopyTo() methods using GCC vector exensions
367 (if available)
368 - ASIO fixes: avoid initializing the device twice, avoid throwing
369 exception when getting parameters from a disconnected device
370
371 * MIDI driver:
372 - added JACK MIDI driver
373 - dispatch bank select as ordinary CC as well, the user might seriously
374 want to (mis)use it for some purpose ("fixed" in all current MIDI
375 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
376 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
377 CoreMidi or AU
378 - fixed mingw-w64 compilation error in MME driver
379 - made program change handling in MIDI thread real-time safe by
380 moving the logic to a non-RT thread
381 - fixed minor memory leak in ALSA driver
382
383 * instruments database:
384 - avoid time consuming samples scanning when adding instruments
385 to the instruments database

387 - Implemented option for adding instruments in separate directories
388 in the instruments database
389 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
390 - work-around for missing fnmatch function on Windows to make
391 instrument database compilable
392 - added instrument database support on Windows
393 works with both standalone mode and VST plugin.
394 the instruments DB file is located in
395 %USERPROFILE%\.linuxsampler\instruments.db which allows different
396 databases for each windows user
397 if no DB is present it automatically creates the .linuxsampler subdir
398 and then creates an empty DB
399 - fixed recursive import, which was broken on Windows
400
401 * Gigasampler format engine:
402 - fixed a memory leak that could happen when a channel was deleted
403 while notes were playing
404 - made it possible to load an instrument even if the audio thread
405 isn't running
406 - added partial support for the "Controller Triggered" MIDI rule,
407 enough for piano gigs with pedal noise samples
408 - minor fix: only mark FX sends as being modified if really the
409 respective FX send MIDI controller was used
410 - added support for GM global device volume SysEx message
411 (can be selected at compile time to either apply globally to the
412 whole sampler [default] or only to the sampler channels that are
413 connected to the respective MIDI input port the SysEx message arrived
414 on)
415 - bugfix: notes triggered at position 0 in the audio buffer were
416 sometimes wrongly killed in the same buffer, causing no sound to
417 be played
418 - added support for chromatic / drumkit mode Roland GS Sysex message
419 which is usally used to switch a part between chromatic sounds and
420 drumkit sounds (as opposed to their common default setting of MIDI
421 part 10 being a drumkit part and all other ones chromatic parts), in
422 LS however one can switch between the first 16 MIDI instrument maps
423 defined for the sampler
424 - made it possible to create multiple sample channels even if the
425 audio thread isn't running
426 - fixed crash when removing channel with active voices (#116)
427 - bugfix: on sample reference changes (instrument editor), only
428 un-cache the respective sample if it's really not used by any
429 sampler engine anymore
430 - re-cache samples in case they were changed by an instrument editor,
431 e.g. when a sample was added while playing (#82)
432 - fixed hanging notes which occured when note-off event had the exact
433 same time stamp as the voice's note-on event and occured both in the
434 same audio fragment cycle (fixes bug #112)
435 - added support for the "fine tune" and "pitch bend range"
436 instrument-level gig parameters
437 - fixed minor artifacts in pitch bend handling
438 - added support for GS Reset SysEx message
439 - allow gig files to use unlimited downward pitch shifting
440 - added a limit check for upward pitch shifting
441 - bugfix: sometimes, when playing a note twice fast, the second
442 note was silent
443 - fixed crash happening when a pitch bend event arrived at the
444 same time a new instrument was loading
445
446 * LSCP server:
447 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
448 react on MIDI data arriving on certain sampler channels (so far only
449 Note-On and Note-Off events are sent via this LSCP event)
450 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
451 react on MIDI data arriving on certain MIDI input devices (so far only
452 Note-On and Note-Off events are sent via this LSCP event)
453 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
454 SET DB_INSTRUMENT FILE_PATH
455 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
456 frontends to send MIDI messages to specific sampler channel
457 - added two additional fields to GET FILE INSTRUMENT INFO command -
458 KEY_BINDINGS and KEYSWITCH_BINDINGS
459 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
460 was incorrect
461 - Optimized the retrieval of the MIDI instrument mappings
462 - added new LSCP command "SET VOICES" to globally alter the maximum
463 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
464 be triggered respectively
465 - added new LSCP command "SET STREAMS" to globally alter the maximum
466 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
467 which will be triggered respectively
468 - bugfix: retry if "select" returns EINTR (this fixes a crash when
469 a gigedit file dialog is opened)
470 - close all connections when LSCPServer is deleted
471 - hard close of all sockets on exit
472 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
473 driver
474
475 * Bug fixes:
476 - fixed a crash which occurs when removing a sampler channel waiting
477 to start instrument loading after another channel
478 - fixed a crash which occurs when removing a sampler channel with
479 instrument loading in progress (bug #113)
480 - fixed termination caused by uncaught exception when adding MIDI
481 instrument with PERSISTENT load mode
482 - fixed possible iterator invalidations when resetting the sampler
483 - fixed memory leaks when issuing the following LSCP commands:
484 GET AUDIO_OUTPUT_DRIVER INFO
485 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
486 GET MIDI_INPUT_DRIVER INFO
487 GET MIDI_INPUT_DRIVER_PARAMETER INFO
488 - fixed possible compilation error when sqlite is not present
489 - fixed orphaned pointers when setting maximum voices limit (bug #118)
490 - fixed crash when changing the audio output device of a sampler
491 channel with loaded instrument and start playing notes
492 - fixed endless loop in Engine::SuspendAll() (bug #120)
493 - fixed a low-level atomic load function that was broken on 64-bit
494 PowerPC, which probably could cause crashes on that platform
495 - fixed a memory management error which could cause a crash when a
496 plugin was unloaded
497 - bugfix: two private structs had the same name, which could cause
498 problems if the linker chose the wrong constructor

501
502
503 Version 0.5.1 (6 December 2007)
504
505 * packaging changes:
506 - added autoconf checks for pthread library
507 - added autoconf check for pthread bug found on certain NPTL-enabled
508 glibc versions (see Gentoo bug report #194076)
509 - added autoconf checks for MS Windows
510
511 * general changes:
512 - bugfix: the thread used by an editor plugin didn't die when the
513 editor closed
514 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
515 out all the space. operator--() did not apply size_mask after
516 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
517 order to avoid problems with the _NonVolatileReader functions.
518 - bugfix: Stream.h: added a missing divide by BytesPerSample in
519 GetWriteSpace(). Since this function is currently only used in
520 the stream's qsort() compare function, it didn't trigger any
521 bugs.
522 - Resampler.h, Synthesizer.h: cubic interpolation now works in
523 24bit mode too. Faster method to read 24bit words on little
524 endian machines (x86): replaced 3 byte reads + shifts with a 1
525 unaligned 32bit read and shift
526 - experimental support for MS Windows (MIDI input via MME, AUDIO
527 output via ASIO)
528 - made handling of SIGINT signal (Ctrl-C) a bit more robust
529 - support for monitoring the total number of active disk streams
530 (new LSCP commands: GET TOTAL_STREAM_COUNT,
531 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
532
533 * AUDIO driver:
534 - added Windows ASIO low latency audio driver
535
536 * MIDI driver:
537 - added MME Windows MIDI driver
538
539 * LSCP server:
540 - added support for Windows style path / filenames, however with
541 forward slash path separators instead of backslash
542 (i.e. "C:/foo/bar.gig")
543 - allow naughty liblscp to send non-string device parameters within
544 apostrophes as well
545 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
546 "LIST FILE INSTRUMENTS <file>" and
547 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
548 about an arbitrary instrument file on the system where the sampler is
549 running on
550
551 Version 0.5.0 (15 October 2007)
552
553 * packaging changes:
554 - config.h is not going to be installed along with liblinuxsampler's
555 API header files anymore
556 - only the API relevant header (and source) files will be exported to
557 the Doxygen API documentation (explicitly listed in Doxyfile.in)
558 - added completely new XCode project files for Mac OSX which is now
559 capable to execute our autoconf environment, thus no need anymore
560 to maintain the compile time configuration file (osx/version.h) for
561 OSX manually (patch by Toshi Nagata)
562 - fixed buggy boolean --enable-foo / --disable-foo configure script
563 parameters
564 - global.h now only covers global definitions that are needed for the
565 C++ API header files, all implementation internal global definitions
566 are now in global_private.h
567 - atomic.h is not exposed to the C++ API anymore
568 - no need to include config.h anymore for using LS's API header files
569 - fixed warnings in API doc generation
570
571 * general changes:
572 - replaced the old, confusing MIDI program change mechanism by a
573 flexible MIDI instrument mapper which allows to map arbitrary
574 (MIDI bank, MIDI program) pairs with arbitrary
575 (engine type, instrument file, file index) triplets which will be
576 loaded on the respective channel when such MIDI program change
577 messages arrive, beside that, each entry allows to define a life-time
578 strategy for the instrument, so the user can define whether the
579 instrument should i.e. be permanently loaded (to be able to switch
580 quickly among sounds) or i.e. loaded just on demand when the
581 respective program change arrives (to safe RAM space), as well as a
582 global volume factor for each entry, so the user can adjust the volume
583 dynamic of his mapped instrument collection without having to modify
584 the instrument files, also one can manage arbitrary amount of such
585 MIDI instrument maps and assign each sampler channel individually
586 a certain map, so that i.e. separation of normal instruments and
587 drumkits is possible
588 - new notification events for tracking changes to audio/MIDI devices,
589 MIDI instrument maps, MIDI instruments, FX sends, global volume.
590 - sampler was limited to load max. 200 instruments in the background
591 due to a constant size RingBuffer FIFO which is now replaced by a
592 dynamic (unlimited) size std::list FIFO
593 - added FX sends, these allow to route audio signals to arbitrary audio
594 output channels for being processed by external effect processors
595 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
596 controllers
597 - global (sampler wide) volume can now be controlled at runtime
598 - Implemented new, improved notification system
599 - fixed compilation errors regarding OSX
600 (patch by Toshi Nagata)
601 - implemented instruments database
602 - added support for escape sequences to the instruments database
603 - added highly experimental support for on-the-fly instrument editing
604 within the sampler's process (by using instrument editor plugins),
605 you'll notice the new "Registered instrument editors:" message on
606 startup, added a new LSCP command:
607 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
608 to spawn a matching instrument editor for the instrument on the
609 given sampler channel, the plugin path can be overridden at compile
610 time with ./configure --enable-plugin-dir=/some/dir
611 - added experimental code for synchronizing instrument editors hosted
612 in the sampler's process to safely edit instruments while playing
613 without a crash (hopefully) by either suspending single regions
614 wherever possible or if unavoidable whole engine(s)
615 - fixed several issues in fundamental "Thread" class: set scheduling
616 policy and priority on thread level, set a minimum stack size for
617 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
618 threads simply inherited properties of starting thread instead of
619 setting their own policy and priority
620 - minor fix in our automatic stack trace mechanism on crashes, the
621 main process did not wait for the stack trace process to finish
622 its output
623 - fixed some minor memory leaks
624 - reenabled assembly features support, at the moment only for
625 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
626 - minor assembly fix in x86 features detection (don't use the PIC
627 register, to avoid relocations in the text segment at runtime)
628 - POSIX callback functions of Thread.h are hidden
629
630 * MIDI driver:
631 - dispatch bank select (MSB and LSB) messages
632
633 * audio driver:
634 - the ALSA audio output driver parameters now reflect the correct
635 parameter value ranges for the respective selected sound card
636 (patch by Till Wimmer, a bit fixed and extended)
637
638 * Gigasampler format engine:
639 - if a filter is used and EG2 finishes before EG1, let the voice
640 die when EG2 has finished (this fixes a problem with clicks and
641 voice starvation for some gigs)
642 - playback is no longer disabled during instrument loading
643 - all notes playing on a channel that changes its instrument keep
644 playing with the old instrument until they get a note off
645 command
646 - EG fix: a release value of zero could cause noises or crash
647 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
648 - EG fine tuning: when attack is zero the EG starts at a level
649 above max sustain level, which means that there is a decay phase
650 even if sustain is 100%
651 - more EG fixes: the level could sometimes go below zero and cause
652 noises or crashes
653 - minor fix of EGDecay (patch by Toshi Nagata)
654 - fixed compiler error when --enable-override-filter-type was
655 supplied to the configure script (fixes #46)
656 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
657 instead of a fix value
658 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
659 127 (solo mode) only kill voices if the respective mode really
660 changed
661
662 * LSCP server:
663 - fixed compile time error for old Bison versions
664 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
665 - parser now supports extended ASCII character set
666 (up to ASCII code 255, i.e. includes now umlauts and accents)
667 - filename arguments in LSCP commands now allow to use escape
668 sequences, that is directly literal as one of: \', \", \\, \n, \r,
669 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
670 code value like \xf2) (fixes bug #24)
671 - the following LSCP commands now also support escape sequences for at
672 least one of their text-based parameters (i.e. name, description):
673 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
674 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
675 "SET DB_INSTRUMENT_DIRECTORY NAME",
676 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
677 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
678 "FIND DB_INSTRUMENT_DIRECTORIES"
679 - returns verbose syntax errors (line and column where syntax error
680 occured, the unexpected character and the actually expected, possible
681 character(s), the latter only if less than 5 possibilities)
682 - made sure that LSCP syntax is not affected by gigedit locale
683 settings
684 - bugfix regarding strings parameter lists: all comma separated lists
685 of strings were treated as being one string containing commas
686 (fixes #57)
687
688 * Bug fixes:
689 - fixed crash occurring on certain LSCP scripts (Bug 39)
690 - another thread safety fix for lscp "load engine" and "set
691 channel audio output device"
692 - fixed a crash which occurs when reassigning the same engine
693 on a sampler channel with connected MIDI device
694 - fixed a crash which occurs when changing the number of ports of a MIDI
695 device connected to a sampler channel to number less then or equal
696 to the index of the port to which the sampler channel is connected.
697 - The previous bindings were not been disconnected when altering
698 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
699 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
700 - The active stream/voice count statistic was incorrect.
701 - notification events were not been sent for some sampler
702 channel changes
703 - added default min and max values to restrict the number of allowed
704 audio output channels and MIDI input ports
705 - the connection to the PCM interface is now closed when destroying
706 an audio output device
707 - files with slash in their path or filename could not be loaded
708
709 * test cases:
710 - updated and fixed (haven't been touched in a while)
711
712 Version 0.4.0 (24 November 2006)
713
714 * packaging changes:
715 - changed deprecated copyright attribute to license; added ldconfig
716 to post-(un)install steps; added devel package for liblinuxsampler;
717 to linuxsampler.spec (RPM)
718 - install necessary development header files for allowing 3rd party
719 applications to link against liblinuxsampler
720 - liblinuxsampler's API documentation can be generated with 'make docs'
721 (Doxygen required)
722 - added benchmark to automatically detect the best triangle LFO
723 implementation (currently either an integer math solution or a
724 di-harmonic approximation), automatic detection can be overriden
725 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
726 configure script argument though (mandatory for cross-compilation)
727 - do not automatically pick optimized gcc flags if the user already
728 provided some on his own (as CXXFLAGS)
729 - added compile time option to disable processing of All-Notes-Off MIDI
730 messages
731 - added compile time options to allow disabling the various audio and
732 MIDI drivers
733 - fixed automatic GCC CPU switch detection on PPC
734 (patch by Ebrahim Mayat)
735
736 * Gigasampler format engine:
737 - extensive synthesis optimization
738 (reimplementation of EGs and LFO(s), removed synthesis parameter
739 prerendering and the synthesis parameter matrix in general, splitting
740 each audio fragment into subfragments now where each subfragment uses
741 constant pitch and filter coefficients. The volume coefficient is
742 linearly interpolated inside a subfragment, unless
743 --disable-interpolate-volume is set.)
744 - fine tuning of the EG modulation parameters
745 - improved filter cutoff calculation by adding support for the
746 following gig parameters: Cutoff freq (used when no cutoff
747 controller is defined), Control invert, Minimum cutoff, Velocity
748 curve and Velocity range. The keyboard tracking now scales
749 cutoff frequency instead of resonance.
750 - added support for gig parameter Resonance.
751 - fixed bug in sysex handling (patch by Juan Linietsky)
752 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
753 which can be overridden with --enable-global-attenuation
754 - EG fixes: made the length of "attack hold" stage more
755 accurate. Release stage can now start before attack stage
756 ends. Cancel release didn't work when sustain was zero. Attack
757 time now has a minimal value to prevent clicks.
758 - fixed pitch changes larger than one octave
759 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
760 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
761 all modes can be altered via standard GM messages, that is CC5 for
762 altering portamento time, CC65 for enabling / disabling portamento
763 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
764 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
765 parameter) and crossfade
766 - added support for the "attenuation controller threshold" gig
767 parameter
768 - added smoothing of volume changes caused by control change
769 messages
770 - sample loop parameters are now taken from the DimensionRegion
771 instead of the wave chunk
772 - fixed keyswitching for v3 gigs with a number of keyswitch splits
773 not equal to a power of two
774 - reimplementation of the filter algorithm. The new filter is more
775 accurate and supports all gig filter types, including bandreject
776 and lowpass turbo.
777 - real support for 24 bit samples - samples are not truncated to
778 16 bits anymore
779 - support for aftertouch (channel pressure, not polyphonic
780 aftertouch)
781 - LFO1 behaviour fixed (dampening from max volume instead of
782 amplifying from 0)
783
784 * LSCP server:
785 - fixed application exit on broken pipe error (fixes bug #20)
786 - fixed the notification messages delay due to lack of
787 network activity (fixes bug #26)
788 - fixed parser bug which occured on space(s) within device parameters
789 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
790
791 * audio driver:
792 - added aRts audio output driver (by no means RT safe)
793
794 * MIDI driver:
795 - fixed legacy sysex code which caused dispatching of MIDI SysEx
796 messages several times instead of once
797 - API extension for MIDI drivers which already supply exact time stamps
798 for events (i.e. for offline rendering based MIDI drivers)
799 - added checks for bad MIDI data
800
801 * linuxsampler application:
802 - show available sampler engine types on startup
803
804 * general changes:
805 - support for muting sampler channels and solo mode of the same, two new
806 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
807 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
808 introduced for this, the behavior is the same like on a mixer console
809 (patch by Grigor Iliev, a bit adjusted). Also added configure option
810 --enable-process-muted-channels which can be used to enable the
811 processing of muted channels.
812 - support for sostenuto pedal
813 - support for monitoring the total number of active voices
814 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
815 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
816 - fixed some memory management errors
817 - fixed some concurrency problems that could lead to crashes when
818 LSCP commands were executed
819 - fixed crash when instrument loading failed previously on the same
820 sampler channel (fixes bug #36)
821
822 Version 0.3.3 (15 July 2005)
823
824 * packaging changes:
825 - fixed compilation with gcc 4.0
826
827 * Gigasampler format engine:
828 - LFO preprocessing was performed even though the respective LFO was
829 disabled by the instrument patch (minor efficiency fix)
830 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
831 for volume ramp downs in the same fragment (needed for current voice
832 stealing implementation) then simply inform the user with a warning
833 about possible click sounds and reduce the volume ramp down
834 appropriately instead of cancelling the audio device connection
835
836 Version 0.3.2 (24 June 2005)
837
838 * packaging changes:
839 - updated autotools build files to compile on OS X
840 (conditional compilation of CoreMIDI and MidiShare drivers)
841 - hand-crafted assembly optimization code can be disabled with
842 './configure --disable-asm' (definitely not recommended)
843 - fixed 'make dist' rule to include all necessary files
844 - require automake (>= 1.5) for 'make -f Makefile.cvs'
845 (due to 'dist-bzip2' automake option)
846
847 * Gigasampler format engine:
848 - support for the gig parameters for "release velocity response" curves
849 - fine tuning of the EGADSR envelope
850 - volume of release triggered samples now depends on note-on velocity,
851 note length and gig parameter "release trigger decay" instead of
852 note-off velocity.
853 - revised voice stealing
854 (fixes crash and endless loop caused by voice stealing)
855 - don't reset scale tuning on instrument or audio output device change
856 - handle key group conflicts right at the beginning of each fragment
857 instead of when the respective voice is actually launched
858 (fixes undefined behavior if stolen voices belonged to a key group -
859 this case was followed by a "killed voice survived" error message)
860 - fixed minor issue with null/silence samples
861 (those stole voices even though they don't need a voice at all which
862 resulted in "voice stealing didn't work out" messages)
863 - don't reset volume, pan, pitch and MIDI controller values on
864 instrument or audio output device change
865
866 * LSCP server:
867 - fixed some crashes (patch by Grigor Iliev, fixes #19)
868 - fixed LSCP event "CHANNEL_INFO" notification
869 (e.g. did not notify on volume changes or MIDI program change events)
870
871 * linuxsampler application:
872 - added command line parameters --lscp-addr and --lscp-port to override
873 default IP address and port of LSCP server
874
875 Version 0.3.1 (24 May 2005)
876
877 * initial release
