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

123 * Host plugins:
124 - AU bugfix: failed to destroy its audio/MIDI devices
125 - Listen to all interfaces on Mac OS X (INADDR_ANY)
126 - VST bugfix: If the host called resume() before and after

138 * MIDI driver:
139 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
140 the ALSA sequencer client name
141 - removed limit of maximum amount of MIDI ports per MIDI device, since
142 there is no reason for this limit

180 - added LSCP commands "SUBSCRIBE EFFECT_INSTANCE_COUNT",
181 "SUBSCRIBE EFFECT_INSTANCE_INFO", "SUBSCRIBE SEND_EFFECT_CHAIN_COUNT",
182 "SUBSCRIBE SEND_EFFECT_CHAIN_INFO"
183
184 * Bug fixes:
185 - Fixed crash which may occur when MIDI key + transpose is out of range
186 - minor valgrind fixes
187 - fixed crash which occurred when changing an already deployed sampler
188 channel to a different engine type
189 - fixed crash when deleting a sampler channel or changing engine
190 type while an instrument load was in progress
191 - bugfix: playing a note while changing the instrument could cause
192 a crash, or give "Handing back unknown region" error messages
193 - bugfix: calling SET VOICES (which Fantasia does on start and
194 refresh) could cause instruments to be unloaded
195 - Mac OS X: fixed name collision of enum in EffectControl and

201 after MIDI/audio device creation failure
202
203 Version 1.0.0 (31 July 2009)
204
205 * packaging changes:
206 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
207 causing e.g. the libgig test to fail when
208 "./configure --disable-jack-driver" was used
209 (patch by Alexis Ballier)
210 - fixed compilation with gcc 4.3
211 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
212 - fixed configure so it detects x86_64 (#107)
213 - fixes for building with newer MinGW versions
214 - fix for building with bison 2.4 (#111)
215 - fixed building with libgig installed in a non-standard directory
216 - minor fix in configure for mmsystem.h detection on MinGW
217 - Windows: look for editor plugins and Fantasia using base
218 directory of liblinuxsampler dll (look in the same directory and one
219 directory above)
220 - configure script fix: removed unconditional use of SSE
221 - fixed building with sqlite installed in a non-standard directory
222 - when cross-compiling, don't try to create instruments.db
223 - fix for new mingw-w64 version, which has usleep
224
225 * general changes:
226 - bugfix: on some POSIX systems instrument editor plugins refused to
227 load as we used a non-portable Linux specific struct field
228 (fixes bug #70, patch by Ronald Baljeu)
229 - fixed endless loop which occured when loading an instrument editor
230 plugin DLL on Windows systems failed
231 - fixed memory leaks that occurred when liblinuxsampler was unloaded
232 - optimized the SynchronizedConfig class so it doesn't wait
233 unnecessarily long after an update
234 - added support for notifying instrument editors on note-on / note-off
235 events (e.g. to highlight the pressed keys on the virtual keyboard
236 of gigedit)
237 - added support for triggering notes by instrument editors (see above)
238 - be verbose on DLL load errors (on Linux)
239 - fixed di-harmonic triangle LFO implementation (this LFO implementation
240 is only used by very few systems, most pick the int math
241 implementation, which is usually faster)
242 - fixes for audio drivers with varying buffer sizes
243 - experimental support for running LinuxSampler as a DSSI, LV2 and
244 VST plugin
245 - notification events for stream/voice count statistics are now sent
246 only when there are actual changes
247 - added memory ordering constraints to improve stability on
248 multi-core and multi-cpu systems
249 - maximum voices and disk streams can now be altered at runtime
250 - fixed CPU feature detection on x86_64 (maybe fixes #108)
251 - automatic stacktrace mechanism is now turned off by default and can
252 be switched on by command line option "--stacktrace" (the automatic
253 stacktrace mechanism seems to be broken on most systems at the moment)
254 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
255 a pointer to the launched InstrumentEditor object
256 - added optional 3rd party user data parameter for following
257 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
258 InstrumentEditor::Launch(),
259 InstrumentManager::LaunchInstrumentEditor()
260 - theoretical fix: made SynchronizedConfig follow C++0x memory
261 model more strictly
262 - fixes for using large audio device buffers
263 - Windows: add the installation directory to the DLL search path
264 when loading an editor plugin (solves problems with VST and
265 gigedit on systems with other GTK versions installed)
266
267 * audio driver:
268 - removed the nonsense audio channel constraint (which was hard coded to
269 max. 100 audio channels) for most audio drivers
270 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
271 opposed to the LSCP specs
272 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
273 reflected the wrong value
274 - fixed a memory management bug in ASIO driver
275 - Makefile fix: JACK_CFLAGS wasn't used
276 - JACK: use jack_client_open instead of the deprecated
277 jack_client_new
278 - added (experimental) CoreAudio driver
279 - applied old fixes to the ASIO driver that were included in the
280 previous binary release but accidentally never committed to CVS
281 (fixes #117)
282 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
283 win64)
284 - VST: added support for sample rate and buffer size changes
285 - VST: close editor (Fantasia) when the VST is removed
286 - VST: avoid opening Fantasia more than once for each VST instance
287 - VST: export main function as "main" on Linux too (fix for
288 energyXT)
289 - VST: changed number of output channels from one stereo to 16
290 stereo
291 - added channel routing, fxsends and midi maps to the settings
292 stored in the plugin state
293 - performance optimization of AudioChannel::MixTo() and
294 AudioChannel::CopyTo() methods using GCC vector exensions
295 (if available)
296 - ASIO fixes: avoid initializing the device twice, avoid throwing
297 exception when getting parameters from a disconnected device
298
299 * MIDI driver:
300 - added JACK MIDI driver
301 - dispatch bank select as ordinary CC as well, the user might seriously
302 want to (mis)use it for some purpose ("fixed" in all current MIDI
303 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
304 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
305 CoreMidi or AU
306 - fixed mingw-w64 compilation error in MME driver
307 - made program change handling in MIDI thread real-time safe by
308 moving the logic to a non-RT thread
309 - fixed minor memory leak in ALSA driver
310
311 * instruments database:
312 - avoid time consuming samples scanning when adding instruments
313 to the instruments database
314 - added support for handling lost files in the instruments database
315 - Implemented option for adding instruments in separate directories
316 in the instruments database
317 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
318 - work-around for missing fnmatch function on Windows to make
319 instrument database compilable
320 - added instrument database support on Windows
321 works with both standalone mode and VST plugin.
322 the instruments DB file is located in
323 %USERPROFILE%\.linuxsampler\instruments.db which allows different
324 databases for each windows user
325 if no DB is present it automatically creates the .linuxsampler subdir
326 and then creates an empty DB
327 - fixed recursive import, which was broken on Windows
328
329 * Gigasampler format engine:
330 - fixed a memory leak that could happen when a channel was deleted
331 while notes were playing
332 - made it possible to load an instrument even if the audio thread
333 isn't running
334 - added partial support for the "Controller Triggered" MIDI rule,
335 enough for piano gigs with pedal noise samples
336 - minor fix: only mark FX sends as being modified if really the
337 respective FX send MIDI controller was used
338 - added support for GM global device volume SysEx message
339 (can be selected at compile time to either apply globally to the
340 whole sampler [default] or only to the sampler channels that are
341 connected to the respective MIDI input port the SysEx message arrived
342 on)
343 - bugfix: notes triggered at position 0 in the audio buffer were
344 sometimes wrongly killed in the same buffer, causing no sound to
345 be played
346 - added support for chromatic / drumkit mode Roland GS Sysex message
347 which is usally used to switch a part between chromatic sounds and
348 drumkit sounds (as opposed to their common default setting of MIDI
349 part 10 being a drumkit part and all other ones chromatic parts), in
350 LS however one can switch between the first 16 MIDI instrument maps
351 defined for the sampler
352 - made it possible to create multiple sample channels even if the
353 audio thread isn't running
354 - fixed crash when removing channel with active voices (#116)
355 - bugfix: on sample reference changes (instrument editor), only
356 un-cache the respective sample if it's really not used by any
357 sampler engine anymore
358 - re-cache samples in case they were changed by an instrument editor,
359 e.g. when a sample was added while playing (#82)
360 - fixed hanging notes which occured when note-off event had the exact
361 same time stamp as the voice's note-on event and occured both in the
362 same audio fragment cycle (fixes bug #112)
363 - added support for the "fine tune" and "pitch bend range"
364 instrument-level gig parameters
365 - fixed minor artifacts in pitch bend handling
366 - added support for GS Reset SysEx message
367 - allow gig files to use unlimited downward pitch shifting
368 - added a limit check for upward pitch shifting
369 - bugfix: sometimes, when playing a note twice fast, the second
370 note was silent
371 - fixed crash happening when a pitch bend event arrived at the
372 same time a new instrument was loading
373
374 * LSCP server:
375 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
376 react on MIDI data arriving on certain sampler channels (so far only
377 Note-On and Note-Off events are sent via this LSCP event)
378 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
379 react on MIDI data arriving on certain MIDI input devices (so far only
380 Note-On and Note-Off events are sent via this LSCP event)
381 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
382 SET DB_INSTRUMENT FILE_PATH
383 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
384 frontends to send MIDI messages to specific sampler channel
385 - added two additional fields to GET FILE INSTRUMENT INFO command -
386 KEY_BINDINGS and KEYSWITCH_BINDINGS
387 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
388 was incorrect
389 - Optimized the retrieval of the MIDI instrument mappings
390 - added new LSCP command "SET VOICES" to globally alter the maximum
391 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
392 be triggered respectively
393 - added new LSCP command "SET STREAMS" to globally alter the maximum
394 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
395 which will be triggered respectively
396 - bugfix: retry if "select" returns EINTR (this fixes a crash when
397 a gigedit file dialog is opened)
398 - close all connections when LSCPServer is deleted
399 - hard close of all sockets on exit
400 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
401 driver
402
403 * Bug fixes:
404 - fixed a crash which occurs when removing a sampler channel waiting
405 to start instrument loading after another channel
406 - fixed a crash which occurs when removing a sampler channel with
407 instrument loading in progress (bug #113)
408 - fixed termination caused by uncaught exception when adding MIDI
409 instrument with PERSISTENT load mode
410 - fixed possible iterator invalidations when resetting the sampler
411 - fixed memory leaks when issuing the following LSCP commands:
412 GET AUDIO_OUTPUT_DRIVER INFO
413 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
414 GET MIDI_INPUT_DRIVER INFO
415 GET MIDI_INPUT_DRIVER_PARAMETER INFO
416 - fixed possible compilation error when sqlite is not present
417 - fixed orphaned pointers when setting maximum voices limit (bug #118)
418 - fixed crash when changing the audio output device of a sampler
419 channel with loaded instrument and start playing notes
420 - fixed endless loop in Engine::SuspendAll() (bug #120)
421 - fixed a low-level atomic load function that was broken on 64-bit
422 PowerPC, which probably could cause crashes on that platform
423 - fixed a memory management error which could cause a crash when a
424 plugin was unloaded
425 - bugfix: two private structs had the same name, which could cause
426 problems if the linker chose the wrong constructor
427 - fixed low-level ConditionServer usage bug that caused lockups on
428 Windows
429
430
431 Version 0.5.1 (6 December 2007)
432
433 * packaging changes:
434 - added autoconf checks for pthread library
435 - added autoconf check for pthread bug found on certain NPTL-enabled
436 glibc versions (see Gentoo bug report #194076)
437 - added autoconf checks for MS Windows
438
439 * general changes:
440 - bugfix: the thread used by an editor plugin didn't die when the
441 editor closed
442 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
443 out all the space. operator--() did not apply size_mask after
444 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
445 order to avoid problems with the _NonVolatileReader functions.
446 - bugfix: Stream.h: added a missing divide by BytesPerSample in
447 GetWriteSpace(). Since this function is currently only used in
448 the stream's qsort() compare function, it didn't trigger any
449 bugs.
450 - Resampler.h, Synthesizer.h: cubic interpolation now works in
451 24bit mode too. Faster method to read 24bit words on little
452 endian machines (x86): replaced 3 byte reads + shifts with a 1
453 unaligned 32bit read and shift
454 - experimental support for MS Windows (MIDI input via MME, AUDIO
455 output via ASIO)
456 - made handling of SIGINT signal (Ctrl-C) a bit more robust
457 - support for monitoring the total number of active disk streams
458 (new LSCP commands: GET TOTAL_STREAM_COUNT,
459 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
460
461 * AUDIO driver:
462 - added Windows ASIO low latency audio driver
463
464 * MIDI driver:
465 - added MME Windows MIDI driver
466
467 * LSCP server:
468 - added support for Windows style path / filenames, however with
469 forward slash path separators instead of backslash
470 (i.e. "C:/foo/bar.gig")
471 - allow naughty liblscp to send non-string device parameters within
472 apostrophes as well
473 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
474 "LIST FILE INSTRUMENTS <file>" and
475 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
476 about an arbitrary instrument file on the system where the sampler is
477 running on
478
479 Version 0.5.0 (15 October 2007)
480
481 * packaging changes:
482 - config.h is not going to be installed along with liblinuxsampler's
483 API header files anymore
484 - only the API relevant header (and source) files will be exported to
485 the Doxygen API documentation (explicitly listed in Doxyfile.in)
486 - added completely new XCode project files for Mac OSX which is now
487 capable to execute our autoconf environment, thus no need anymore
488 to maintain the compile time configuration file (osx/version.h) for
489 OSX manually (patch by Toshi Nagata)
490 - fixed buggy boolean --enable-foo / --disable-foo configure script
491 parameters
492 - global.h now only covers global definitions that are needed for the
493 C++ API header files, all implementation internal global definitions
494 are now in global_private.h
495 - atomic.h is not exposed to the C++ API anymore
496 - no need to include config.h anymore for using LS's API header files
497 - fixed warnings in API doc generation
498
499 * general changes:
500 - replaced the old, confusing MIDI program change mechanism by a
501 flexible MIDI instrument mapper which allows to map arbitrary
502 (MIDI bank, MIDI program) pairs with arbitrary
503 (engine type, instrument file, file index) triplets which will be
504 loaded on the respective channel when such MIDI program change
505 messages arrive, beside that, each entry allows to define a life-time
506 strategy for the instrument, so the user can define whether the
507 instrument should i.e. be permanently loaded (to be able to switch
508 quickly among sounds) or i.e. loaded just on demand when the
509 respective program change arrives (to safe RAM space), as well as a
510 global volume factor for each entry, so the user can adjust the volume
511 dynamic of his mapped instrument collection without having to modify
512 the instrument files, also one can manage arbitrary amount of such
513 MIDI instrument maps and assign each sampler channel individually
514 a certain map, so that i.e. separation of normal instruments and
515 drumkits is possible
516 - new notification events for tracking changes to audio/MIDI devices,
517 MIDI instrument maps, MIDI instruments, FX sends, global volume.
518 - sampler was limited to load max. 200 instruments in the background
519 due to a constant size RingBuffer FIFO which is now replaced by a
520 dynamic (unlimited) size std::list FIFO
521 - added FX sends, these allow to route audio signals to arbitrary audio
522 output channels for being processed by external effect processors
523 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
524 controllers
525 - global (sampler wide) volume can now be controlled at runtime
526 - Implemented new, improved notification system
527 - fixed compilation errors regarding OSX
528 (patch by Toshi Nagata)
529 - implemented instruments database
530 - added support for escape sequences to the instruments database
531 - added highly experimental support for on-the-fly instrument editing
532 within the sampler's process (by using instrument editor plugins),
533 you'll notice the new "Registered instrument editors:" message on
534 startup, added a new LSCP command:
535 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
536 to spawn a matching instrument editor for the instrument on the
537 given sampler channel, the plugin path can be overridden at compile
538 time with ./configure --enable-plugin-dir=/some/dir
539 - added experimental code for synchronizing instrument editors hosted
540 in the sampler's process to safely edit instruments while playing
541 without a crash (hopefully) by either suspending single regions
542 wherever possible or if unavoidable whole engine(s)
543 - fixed several issues in fundamental "Thread" class: set scheduling
544 policy and priority on thread level, set a minimum stack size for
545 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
546 threads simply inherited properties of starting thread instead of
547 setting their own policy and priority
548 - minor fix in our automatic stack trace mechanism on crashes, the
549 main process did not wait for the stack trace process to finish
550 its output
551 - fixed some minor memory leaks
552 - reenabled assembly features support, at the moment only for
553 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
554 - minor assembly fix in x86 features detection (don't use the PIC
555 register, to avoid relocations in the text segment at runtime)
556 - POSIX callback functions of Thread.h are hidden
557
558 * MIDI driver:
559 - dispatch bank select (MSB and LSB) messages
560
561 * audio driver:
562 - the ALSA audio output driver parameters now reflect the correct
563 parameter value ranges for the respective selected sound card
564 (patch by Till Wimmer, a bit fixed and extended)
565
566 * Gigasampler format engine:
567 - if a filter is used and EG2 finishes before EG1, let the voice
568 die when EG2 has finished (this fixes a problem with clicks and
569 voice starvation for some gigs)
570 - playback is no longer disabled during instrument loading
571 - all notes playing on a channel that changes its instrument keep
572 playing with the old instrument until they get a note off
573 command
574 - EG fix: a release value of zero could cause noises or crash
575 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
576 - EG fine tuning: when attack is zero the EG starts at a level
577 above max sustain level, which means that there is a decay phase
578 even if sustain is 100%
579 - more EG fixes: the level could sometimes go below zero and cause
580 noises or crashes
581 - minor fix of EGDecay (patch by Toshi Nagata)
582 - fixed compiler error when --enable-override-filter-type was
583 supplied to the configure script (fixes #46)
584 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
585 instead of a fix value
586 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
587 127 (solo mode) only kill voices if the respective mode really
588 changed
589
590 * LSCP server:
591 - fixed compile time error for old Bison versions
592 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
593 - parser now supports extended ASCII character set
594 (up to ASCII code 255, i.e. includes now umlauts and accents)
595 - filename arguments in LSCP commands now allow to use escape
596 sequences, that is directly literal as one of: \', \", \\, \n, \r,
597 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
598 code value like \xf2) (fixes bug #24)
599 - the following LSCP commands now also support escape sequences for at
600 least one of their text-based parameters (i.e. name, description):
601 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
602 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
603 "SET DB_INSTRUMENT_DIRECTORY NAME",
604 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
605 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
606 "FIND DB_INSTRUMENT_DIRECTORIES"
607 - returns verbose syntax errors (line and column where syntax error
608 occured, the unexpected character and the actually expected, possible
609 character(s), the latter only if less than 5 possibilities)
610 - made sure that LSCP syntax is not affected by gigedit locale
611 settings
612 - bugfix regarding strings parameter lists: all comma separated lists
613 of strings were treated as being one string containing commas
614 (fixes #57)
615
616 * Bug fixes:
617 - fixed crash occurring on certain LSCP scripts (Bug 39)
618 - another thread safety fix for lscp "load engine" and "set
619 channel audio output device"
620 - fixed a crash which occurs when reassigning the same engine
621 on a sampler channel with connected MIDI device
622 - fixed a crash which occurs when changing the number of ports of a MIDI
623 device connected to a sampler channel to number less then or equal
624 to the index of the port to which the sampler channel is connected.
625 - The previous bindings were not been disconnected when altering
626 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
627 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
628 - The active stream/voice count statistic was incorrect.
629 - notification events were not been sent for some sampler
630 channel changes
631 - added default min and max values to restrict the number of allowed
632 audio output channels and MIDI input ports
633 - the connection to the PCM interface is now closed when destroying
634 an audio output device
635 - files with slash in their path or filename could not be loaded
636
637 * test cases:
638 - updated and fixed (haven't been touched in a while)
639
640 Version 0.4.0 (24 November 2006)
641
642 * packaging changes:
643 - changed deprecated copyright attribute to license; added ldconfig
644 to post-(un)install steps; added devel package for liblinuxsampler;
645 to linuxsampler.spec (RPM)
646 - install necessary development header files for allowing 3rd party
647 applications to link against liblinuxsampler
648 - liblinuxsampler's API documentation can be generated with 'make docs'
649 (Doxygen required)
650 - added benchmark to automatically detect the best triangle LFO
651 implementation (currently either an integer math solution or a
652 di-harmonic approximation), automatic detection can be overriden
653 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
654 configure script argument though (mandatory for cross-compilation)
655 - do not automatically pick optimized gcc flags if the user already
656 provided some on his own (as CXXFLAGS)
657 - added compile time option to disable processing of All-Notes-Off MIDI
658 messages
659 - added compile time options to allow disabling the various audio and
660 MIDI drivers
661 - fixed automatic GCC CPU switch detection on PPC
662 (patch by Ebrahim Mayat)
663
664 * Gigasampler format engine:
665 - extensive synthesis optimization
666 (reimplementation of EGs and LFO(s), removed synthesis parameter
667 prerendering and the synthesis parameter matrix in general, splitting
668 each audio fragment into subfragments now where each subfragment uses
669 constant pitch and filter coefficients. The volume coefficient is
670 linearly interpolated inside a subfragment, unless
671 --disable-interpolate-volume is set.)
672 - fine tuning of the EG modulation parameters
673 - improved filter cutoff calculation by adding support for the
674 following gig parameters: Cutoff freq (used when no cutoff
675 controller is defined), Control invert, Minimum cutoff, Velocity
676 curve and Velocity range. The keyboard tracking now scales
677 cutoff frequency instead of resonance.
678 - added support for gig parameter Resonance.
679 - fixed bug in sysex handling (patch by Juan Linietsky)
680 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
681 which can be overridden with --enable-global-attenuation
682 - EG fixes: made the length of "attack hold" stage more
683 accurate. Release stage can now start before attack stage
684 ends. Cancel release didn't work when sustain was zero. Attack
685 time now has a minimal value to prevent clicks.
686 - fixed pitch changes larger than one octave
687 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
688 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
689 all modes can be altered via standard GM messages, that is CC5 for
690 altering portamento time, CC65 for enabling / disabling portamento
691 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
692 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
693 parameter) and crossfade
694 - added support for the "attenuation controller threshold" gig
695 parameter
696 - added smoothing of volume changes caused by control change
697 messages
698 - sample loop parameters are now taken from the DimensionRegion
699 instead of the wave chunk
700 - fixed keyswitching for v3 gigs with a number of keyswitch splits
701 not equal to a power of two
702 - reimplementation of the filter algorithm. The new filter is more
703 accurate and supports all gig filter types, including bandreject
704 and lowpass turbo.
705 - real support for 24 bit samples - samples are not truncated to
706 16 bits anymore
707 - support for aftertouch (channel pressure, not polyphonic
708 aftertouch)
709 - LFO1 behaviour fixed (dampening from max volume instead of
710 amplifying from 0)
711
712 * LSCP server:
713 - fixed application exit on broken pipe error (fixes bug #20)
714 - fixed the notification messages delay due to lack of
715 network activity (fixes bug #26)
716 - fixed parser bug which occured on space(s) within device parameters
717 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
718
719 * audio driver:
720 - added aRts audio output driver (by no means RT safe)
721
722 * MIDI driver:
723 - fixed legacy sysex code which caused dispatching of MIDI SysEx
724 messages several times instead of once
725 - API extension for MIDI drivers which already supply exact time stamps
726 for events (i.e. for offline rendering based MIDI drivers)
727 - added checks for bad MIDI data
728
729 * linuxsampler application:
730 - show available sampler engine types on startup
731
732 * general changes:
733 - support for muting sampler channels and solo mode of the same, two new
734 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
735 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
736 introduced for this, the behavior is the same like on a mixer console
737 (patch by Grigor Iliev, a bit adjusted). Also added configure option
738 --enable-process-muted-channels which can be used to enable the
739 processing of muted channels.
740 - support for sostenuto pedal
741 - support for monitoring the total number of active voices
742 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
743 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
744 - fixed some memory management errors
745 - fixed some concurrency problems that could lead to crashes when
746 LSCP commands were executed
747 - fixed crash when instrument loading failed previously on the same
748 sampler channel (fixes bug #36)
749
750 Version 0.3.3 (15 July 2005)
751
752 * packaging changes:
753 - fixed compilation with gcc 4.0
754
755 * Gigasampler format engine:
756 - LFO preprocessing was performed even though the respective LFO was
757 disabled by the instrument patch (minor efficiency fix)
758 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
759 for volume ramp downs in the same fragment (needed for current voice
760 stealing implementation) then simply inform the user with a warning
761 about possible click sounds and reduce the volume ramp down
762 appropriately instead of cancelling the audio device connection
763
764 Version 0.3.2 (24 June 2005)
765
766 * packaging changes:
767 - updated autotools build files to compile on OS X
768 (conditional compilation of CoreMIDI and MidiShare drivers)
769 - hand-crafted assembly optimization code can be disabled with
770 './configure --disable-asm' (definitely not recommended)
771 - fixed 'make dist' rule to include all necessary files
772 - require automake (>= 1.5) for 'make -f Makefile.cvs'
773 (due to 'dist-bzip2' automake option)
774
775 * Gigasampler format engine:
776 - support for the gig parameters for "release velocity response" curves
777 - fine tuning of the EGADSR envelope
778 - volume of release triggered samples now depends on note-on velocity,
779 note length and gig parameter "release trigger decay" instead of
780 note-off velocity.
781 - revised voice stealing
782 (fixes crash and endless loop caused by voice stealing)
783 - don't reset scale tuning on instrument or audio output device change
784 - handle key group conflicts right at the beginning of each fragment
785 instead of when the respective voice is actually launched
786 (fixes undefined behavior if stolen voices belonged to a key group -
787 this case was followed by a "killed voice survived" error message)
788 - fixed minor issue with null/silence samples
789 (those stole voices even though they don't need a voice at all which
790 resulted in "voice stealing didn't work out" messages)
791 - don't reset volume, pan, pitch and MIDI controller values on
792 instrument or audio output device change
793
794 * LSCP server:
795 - fixed some crashes (patch by Grigor Iliev, fixes #19)
796 - fixed LSCP event "CHANNEL_INFO" notification
797 (e.g. did not notify on volume changes or MIDI program change events)
798
799 * linuxsampler application:
800 - added command line parameters --lscp-addr and --lscp-port to override
801 default IP address and port of LSCP server
802
803 Version 0.3.1 (24 May 2005)
804
805 * initial release
