File size: 40291 byte(s)
* sf2 engine: fine-tuned amplitude EG (by switching from gig to sfz EG)
* sfz engine: added support for EG hold (ampeg_hold)
* Mac OS X: made it possible to specify plugin installation dir to

1 Version CVS HEAD (?)
3 * plugin changes:
4 - LV2 Persist + Files support (patch by David Robillard)
6 * packaging changes:
7 - fixed building with newer MinGW-w64
8 - Mac OS X: support the new dir for Core Audio SDK
9 - Mac OS X: fixed building outside source directory
10 - made sure all source files for hostplugins are included when
11 doing "make dist"
12 - removed empty directories left from the cvs to svn migration
13 - fixed compilation with gcc 4.6.1
14 - another "make dist" fix, for the LV2 plugin
15 - made --enable-pthread-testcancel default on Mac OS X
16 - minor Makefile fix for building lscpparser when build and source
17 directories are separate
18 - Mac OS X: made it possible to specify plugin installation dir to
19 configure
21 * general changes:
22 - Refactoring: moved the independent code from
23 the Gigasampler format engine to base classes
24 - command line option '--profile' is currently disabled, since the
25 respective profiling code is currently broken
26 - Introduced support for optional environment variable
27 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
28 where the sampler shall look for instrument editor plugins
29 (patch by Luis Garrido, slightly modified).
30 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
31 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
32 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
33 note (in this implementation of the sampler its simply hard routed to
34 the 1st effect send of the sampler channel, no matter what the actual
35 effect type is)
36 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
37 note (in this implementation of the sampler its simply hard routed to
38 the 2nd effect send of the sampler channel, no matter what the actual
39 effect type is)
40 - implemented support for internal LADSPA effects
41 - raised limit of program change queue from 100 to 512
42 (as suggested by Alex Stone)
44 * Gigasampler format engine:
45 - implemented the "round robin keyboard" dimension

58 - allow non-numerical key values ("C#4" for example)
59 - "key" opcode now sets pitch_keycenter too
60 - fixed error when unloading instrument with same sample used by
61 multiple regions

87 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
88 cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
89 cutoff_cc, cutoff_chanaft.
90 - bugfix: zero ampeg_sustain didn't work
91 - added support for velocity effect on amplifier envelope time
92 (ampeg_vel2attack, ampeg_vel2decay, ampeg_vel2sustain and
93 ampeg_vel2release)

108 * Host plugins:
109 - AU bugfix: failed to destroy its audio/MIDI devices
110 - Listen to all interfaces on Mac OS X (INADDR_ANY)
111 - VST bugfix: If the host called resume() before and after
112 changing sample rate or block size, the number of channels was
113 incorrectly set to two. This caused silence in Cubase 5.
114 - save engine type (gig, sfz or sf2) in plugin state

121 specified
123 * MIDI driver:
124 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
125 the ALSA sequencer client name
126 - removed limit of maximum amount of MIDI ports per MIDI device, since
127 there is no reason for this limit
129 * audio driver:
130 - ASIO driver fixes for newer gcc versions (fix from PortAudio)

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