* sfz engine: added support for velocity effect on amplifier envelope
  time (ampeg_vel2attack, ampeg_vel2decay, ampeg_vel2sustain and
  ampeg_vel2release)

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
9 * general changes:
10 - Refactoring: moved the independent code from
11 the Gigasampler format engine to base classes
12 - command line option '--profile' is currently disabled, since the
13 respective profiling code is currently broken
14 - Introduced support for optional environment variable
15 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
16 where the sampler shall look for instrument editor plugins
17 (patch by Luis Garrido, slightly modified).
18 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
19 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
20 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
21 note (in this implementation of the sampler its simply hard routed to
22 the 1st effect send of the sampler channel, no matter what the actual
23 effect type is)
24 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
25 note (in this implementation of the sampler its simply hard routed to
26 the 2nd effect send of the sampler channel, no matter what the actual
27 effect type is)
28 - implemented support for internal LADSPA effects
29 - raised limit of program change queue from 100 to 512
30 (as suggested by Alex Stone)
31
32 * Gigasampler format engine:
33 - implemented the "round robin keyboard" dimension
34 - fixed round robin and random dimensions for cases when number of
35 dimension zones is not a power of two
36 - made round robin use a counter for each region instead of each
37 key
38
39 * SFZ format engine:
40 - Initial implementation (not usable yet)
41 - added support for v2 multiple stage envelope generators

43 one from the gig engine
44 - fixed memory leak and memory handling errors
45 - added support for trigger=first, trigger=legato and sw_previous
46 - allow non-numerical key values ("C#4" for example)
47 - "key" opcode now sets pitch_keycenter too
48 - fixed error when unloading instrument with same sample used by
49 multiple regions

73 not set in sfz file
74 - implemeted filters. Filter types: lowpass, bandpass, bandreject
75 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
76 cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
77 cutoff_cc, cutoff_chanaft.
78 - bugfix: zero ampeg_sustain didn't work
79 - added support for velocity effect on amplifier envelope time
80 (ampeg_vel2attack, ampeg_vel2decay, ampeg_vel2sustain and

82
83 * SoundFont format engine:
84 - Initial implementation (not usable yet)
85 - RT-safeness: avoid malloc in audio thread

93
94 * Host plugins:
95 - AU bugfix: failed to destroy its audio/MIDI devices
96 - Listen to all interfaces on Mac OS X (INADDR_ANY)
97 - VST bugfix: If the host called resume() before and after
98 changing sample rate or block size, the number of channels was
99 incorrectly set to two. This caused silence in Cubase 5.
100 - save engine type (gig, sfz or sf2) in plugin state
101 - VST: when opening Fantasia, look for both 32 and 64 bit Java on
102 64 bit Windows

104 * MIDI driver:
105 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
106 the ALSA sequencer client name
107 - removed limit of maximum amount of MIDI ports per MIDI device, since
108 there is no reason for this limit
109

144 <fx_send_id> <effect_chain> <chain_pos>"
145 - added LSCP command "REMOVE FX_SEND EFFECT <sampler_channel> <fx_send_id>"
146
147 * Bug fixes:
148 - Fixed crash which may occur when MIDI key + transpose is out of range
149 - minor valgrind fixes
150 - fixed crash which occured when changing an already deployed sampler
151 channel to a different engine type
152 - fixed crash when deleting a sampler channel or changing engine
153 type while an instrument load was in progress
154 - bugfix: playing a note while changing the instrument could cause
155 a crash, or give "Handing back unknown region" error messages
156 - bugfix: calling SET VOICES (which Fantasia does on start and
157 refresh) could cause instruments to be unloaded
158
159 Version 1.0.0 (31 July 2009)
160
161 * packaging changes:
162 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
163 causing e.g. the libgig test to fail when
164 "./configure --disable-jack-driver" was used
165 (patch by Alexis Ballier)
166 - fixed compilation with gcc 4.3
167 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
168 - fixed configure so it detects x86_64 (#107)
169 - fixes for building with newer MinGW versions
170 - fix for building with bison 2.4 (#111)
171 - fixed building with libgig installed in a non-standard directory
172 - minor fix in configure for mmsystem.h detection on MinGW
173 - Windows: look for editor plugins and Fantasia using base
174 directory of liblinuxsampler dll (look in the same directory and one
175 directory above)
176 - configure script fix: removed unconditional use of SSE
177 - fixed building with sqlite installed in a non-standard directory
178 - when cross-compiling, don't try to create instruments.db
179 - fix for new mingw-w64 version, which has usleep
180
181 * general changes:
182 - bugfix: on some POSIX systems instrument editor plugins refused to
183 load as we used a non-portable Linux specific struct field
184 (fixes bug #70, patch by Ronald Baljeu)
185 - fixed endless loop which occured when loading an instrument editor
186 plugin DLL on Windows systems failed
187 - fixed memory leaks that occurred when liblinuxsampler was unloaded
188 - optimized the SynchronizedConfig class so it doesn't wait
189 unnecessarily long after an update
190 - added support for notifying instrument editors on note-on / note-off
191 events (e.g. to highlight the pressed keys on the virtual keyboard
192 of gigedit)
193 - added support for triggering notes by instrument editors (see above)
194 - be verbose on DLL load errors (on Linux)
195 - fixed di-harmonic triangle LFO implementation (this LFO implementation
196 is only used by very few systems, most pick the int math
197 implementation, which is usually faster)
198 - fixes for audio drivers with varying buffer sizes
199 - experimental support for running LinuxSampler as a DSSI, LV2 and
200 VST plugin
201 - notification events for stream/voice count statistics are now sent
202 only when there are actual changes
203 - added memory ordering constraints to improve stability on
204 multi-core and multi-cpu systems
205 - maximum voices and disk streams can now be altered at runtime
206 - fixed CPU feature detection on x86_64 (maybe fixes #108)
207 - automatic stacktrace mechanism is now turned off by default and can
208 be switched on by command line option "--stacktrace" (the automatic
209 stacktrace mechanism seems to be broken on most systems at the moment)
210 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
211 a pointer to the launched InstrumentEditor object
212 - added optional 3rd party user data parameter for following
213 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
214 InstrumentEditor::Launch(),
215 InstrumentManager::LaunchInstrumentEditor()
216 - theoretical fix: made SynchronizedConfig follow C++0x memory
217 model more strictly
218 - fixes for using large audio device buffers
219 - Windows: add the installation directory to the DLL search path
220 when loading an editor plugin (solves problems with VST and
221 gigedit on systems with other GTK versions installed)
222
223 * audio driver:
224 - removed the nonsense audio channel constraint (which was hard coded to
225 max. 100 audio channels) for most audio drivers
226 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
227 opposed to the LSCP specs
228 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
229 reflected the wrong value
230 - fixed a memory management bug in ASIO driver
231 - Makefile fix: JACK_CFLAGS wasn't used
232 - JACK: use jack_client_open instead of the deprecated
233 jack_client_new
234 - added (experimental) CoreAudio driver
235 - applied old fixes to the ASIO driver that were included in the
236 previous binary release but accidentally never committed to CVS
237 (fixes #117)
238 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
239 win64)
240 - VST: added support for sample rate and buffer size changes
241 - VST: close editor (Fantasia) when the VST is removed
242 - VST: avoid opening Fantasia more than once for each VST instance
243 - VST: export main function as "main" on Linux too (fix for
244 energyXT)
245 - VST: changed number of output channels from one stereo to 16
246 stereo
247 - added channel routing, fxsends and midi maps to the settings
248 stored in the plugin state
249 - performance optimization of AudioChannel::MixTo() and
250 AudioChannel::CopyTo() methods using GCC vector exensions
251 (if available)
252 - ASIO fixes: avoid initializing the device twice, avoid throwing
253 exception when getting parameters from a disconnected device
254
255 * MIDI driver:
256 - added JACK MIDI driver
257 - dispatch bank select as ordinary CC as well, the user might seriously
258 want to (mis)use it for some purpose ("fixed" in all current MIDI
259 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
260 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
261 CoreMidi or AU
262 - fixed mingw-w64 compilation error in MME driver
263 - made program change handling in MIDI thread real-time safe by
264 moving the logic to a non-RT thread
265 - fixed minor memory leak in ALSA driver
266
267 * instruments database:
268 - avoid time consuming samples scanning when adding instruments
269 to the instruments database
270 - added support for handling lost files in the instruments database
271 - Implemented option for adding instruments in separate directories
272 in the instruments database
273 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
274 - work-around for missing fnmatch function on Windows to make
275 instrument database compilable
276 - added instrument database support on Windows
277 works with both standalone mode and VST plugin.
278 the instruments DB file is located in
279 %USERPROFILE%\.linuxsampler\instruments.db which allows different
280 databases for each windows user
281 if no DB is present it automatically creates the .linuxsampler subdir
282 and then creates an empty DB
283 - fixed recursive import, which was broken on Windows
284
285 * Gigasampler format engine:
286 - fixed a memory leak that could happen when a channel was deleted
287 while notes were playing
288 - made it possible to load an instrument even if the audio thread
289 isn't running
290 - added partial support for the "Controller Triggered" MIDI rule,
291 enough for piano gigs with pedal noise samples
292 - minor fix: only mark FX sends as being modified if really the
293 respective FX send MIDI controller was used
294 - added support for GM global device volume SysEx message
295 (can be selected at compile time to either apply globally to the
296 whole sampler [default] or only to the sampler channels that are
297 connected to the respective MIDI input port the SysEx message arrived
298 on)
299 - bugfix: notes triggered at position 0 in the audio buffer were
300 sometimes wrongly killed in the same buffer, causing no sound to
301 be played
302 - added support for chromatic / drumkit mode Roland GS Sysex message
303 which is usally used to switch a part between chromatic sounds and
304 drumkit sounds (as opposed to their common default setting of MIDI
305 part 10 being a drumkit part and all other ones chromatic parts), in
306 LS however one can switch between the first 16 MIDI instrument maps
307 defined for the sampler
308 - made it possible to create multiple sample channels even if the
309 audio thread isn't running
310 - fixed crash when removing channel with active voices (#116)
311 - bugfix: on sample reference changes (instrument editor), only
312 un-cache the respective sample if it's really not used by any
313 sampler engine anymore
314 - re-cache samples in case they were changed by an instrument editor,
315 e.g. when a sample was added while playing (#82)
316 - fixed hanging notes which occured when note-off event had the exact
317 same time stamp as the voice's note-on event and occured both in the
318 same audio fragment cycle (fixes bug #112)
319 - added support for the "fine tune" and "pitch bend range"
320 instrument-level gig parameters
321 - fixed minor artifacts in pitch bend handling
322 - added support for GS Reset SysEx message
323 - allow gig files to use unlimited downward pitch shifting
324 - added a limit check for upward pitch shifting
325 - bugfix: sometimes, when playing a note twice fast, the second
326 note was silent
327 - fixed crash happening when a pitch bend event arrived at the
328 same time a new instrument was loading
329
330 * LSCP server:
331 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
332 react on MIDI data arriving on certain sampler channels (so far only
333 Note-On and Note-Off events are sent via this LSCP event)
334 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
335 react on MIDI data arriving on certain MIDI input devices (so far only
336 Note-On and Note-Off events are sent via this LSCP event)
337 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
338 SET DB_INSTRUMENT FILE_PATH
339 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
340 frontends to send MIDI messages to specific sampler channel
341 - added two additional fields to GET FILE INSTRUMENT INFO command -
342 KEY_BINDINGS and KEYSWITCH_BINDINGS
343 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
344 was incorrect
345 - Optimized the retrieval of the MIDI instrument mappings
346 - added new LSCP command "SET VOICES" to globally alter the maximum
347 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
348 be triggered respectively
349 - added new LSCP command "SET STREAMS" to globally alter the maximum
350 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
351 which will be triggered respectively
352 - bugfix: retry if "select" returns EINTR (this fixes a crash when
353 a gigedit file dialog is opened)
354 - close all connections when LSCPServer is deleted
355 - hard close of all sockets on exit
356 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
357 driver
358
359 * Bug fixes:
360 - fixed a crash which occurs when removing a sampler channel waiting
361 to start instrument loading after another channel
362 - fixed a crash which occurs when removing a sampler channel with
363 instrument loading in progress (bug #113)
364 - fixed termination caused by uncaught exception when adding MIDI
365 instrument with PERSISTENT load mode
366 - fixed possible iterator invalidations when resetting the sampler
367 - fixed memory leaks when issuing the following LSCP commands:
368 GET AUDIO_OUTPUT_DRIVER INFO
369 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
370 GET MIDI_INPUT_DRIVER INFO
371 GET MIDI_INPUT_DRIVER_PARAMETER INFO
372 - fixed possible compilation error when sqlite is not present
373 - fixed orphaned pointers when setting maximum voices limit (bug #118)
374 - fixed crash when changing the audio output device of a sampler
375 channel with loaded instrument and start playing notes
376 - fixed endless loop in Engine::SuspendAll() (bug #120)
377 - fixed a low-level atomic load function that was broken on 64-bit
378 PowerPC, which probably could cause crashes on that platform
379 - fixed a memory management error which could cause a crash when a
380 plugin was unloaded
381 - bugfix: two private structs had the same name, which could cause
382 problems if the linker chose the wrong constructor
383 - fixed low-level ConditionServer usage bug that caused lockups on
384 Windows
385
386
387 Version 0.5.1 (6 December 2007)
388
389 * packaging changes:
390 - added autoconf checks for pthread library
391 - added autoconf check for pthread bug found on certain NPTL-enabled
392 glibc versions (see Gentoo bug report #194076)
393 - added autoconf checks for MS Windows
394
395 * general changes:
396 - bugfix: the thread used by an editor plugin didn't die when the
397 editor closed
398 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
399 out all the space. operator--() did not apply size_mask after
400 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
401 order to avoid problems with the _NonVolatileReader functions.
402 - bugfix: Stream.h: added a missing divide by BytesPerSample in
403 GetWriteSpace(). Since this function is currently only used in
404 the stream's qsort() compare function, it didn't trigger any
405 bugs.
406 - Resampler.h, Synthesizer.h: cubic interpolation now works in
407 24bit mode too. Faster method to read 24bit words on little
408 endian machines (x86): replaced 3 byte reads + shifts with a 1
409 unaligned 32bit read and shift
410 - experimental support for MS Windows (MIDI input via MME, AUDIO
411 output via ASIO)
412 - made handling of SIGINT signal (Ctrl-C) a bit more robust
413 - support for monitoring the total number of active disk streams
414 (new LSCP commands: GET TOTAL_STREAM_COUNT,
415 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
416
417 * AUDIO driver:
418 - added Windows ASIO low latency audio driver
419
420 * MIDI driver:
421 - added MME Windows MIDI driver
422
423 * LSCP server:
424 - added support for Windows style path / filenames, however with
425 forward slash path separators instead of backslash
426 (i.e. "C:/foo/bar.gig")
427 - allow naughty liblscp to send non-string device parameters within
428 apostrophes as well
429 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
430 "LIST FILE INSTRUMENTS <file>" and
431 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
432 about an arbitrary instrument file on the system where the sampler is
433 running on
434
435 Version 0.5.0 (15 October 2007)
436
437 * packaging changes:
438 - config.h is not going to be installed along with liblinuxsampler's
439 API header files anymore
440 - only the API relevant header (and source) files will be exported to
441 the Doxygen API documentation (explicitly listed in Doxyfile.in)
442 - added completely new XCode project files for Mac OSX which is now
443 capable to execute our autoconf environment, thus no need anymore
444 to maintain the compile time configuration file (osx/version.h) for
445 OSX manually (patch by Toshi Nagata)
446 - fixed buggy boolean --enable-foo / --disable-foo configure script
447 parameters
448 - global.h now only covers global definitions that are needed for the
449 C++ API header files, all implementation internal global definitions
450 are now in global_private.h
451 - atomic.h is not exposed to the C++ API anymore
452 - no need to include config.h anymore for using LS's API header files
453 - fixed warnings in API doc generation
454
455 * general changes:
456 - replaced the old, confusing MIDI program change mechanism by a
457 flexible MIDI instrument mapper which allows to map arbitrary
458 (MIDI bank, MIDI program) pairs with arbitrary
459 (engine type, instrument file, file index) triplets which will be
460 loaded on the respective channel when such MIDI program change
461 messages arrive, beside that, each entry allows to define a life-time
462 strategy for the instrument, so the user can define whether the
463 instrument should i.e. be permanently loaded (to be able to switch
464 quickly among sounds) or i.e. loaded just on demand when the
465 respective program change arrives (to safe RAM space), as well as a
466 global volume factor for each entry, so the user can adjust the volume
467 dynamic of his mapped instrument collection without having to modify
468 the instrument files, also one can manage arbitrary amount of such
469 MIDI instrument maps and assign each sampler channel individually
470 a certain map, so that i.e. separation of normal instruments and
471 drumkits is possible
472 - new notification events for tracking changes to audio/MIDI devices,
473 MIDI instrument maps, MIDI instruments, FX sends, global volume.
474 - sampler was limited to load max. 200 instruments in the background
475 due to a constant size RingBuffer FIFO which is now replaced by a
476 dynamic (unlimited) size std::list FIFO
477 - added FX sends, these allow to route audio signals to arbitrary audio
478 output channels for being processed by external effect processors
479 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
480 controllers
481 - global (sampler wide) volume can now be controlled at runtime
482 - Implemented new, improved notification system
483 - fixed compilation errors regarding OSX
484 (patch by Toshi Nagata)
485 - implemented instruments database
486 - added support for escape sequences to the instruments database
487 - added highly experimental support for on-the-fly instrument editing
488 within the sampler's process (by using instrument editor plugins),
489 you'll notice the new "Registered instrument editors:" message on
490 startup, added a new LSCP command:
491 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
492 to spawn a matching instrument editor for the instrument on the
493 given sampler channel, the plugin path can be overridden at compile
494 time with ./configure --enable-plugin-dir=/some/dir
495 - added experimental code for synchronizing instrument editors hosted
496 in the sampler's process to safely edit instruments while playing
497 without a crash (hopefully) by either suspending single regions
498 wherever possible or if unavoidable whole engine(s)
499 - fixed several issues in fundamental "Thread" class: set scheduling
500 policy and priority on thread level, set a minimum stack size for
501 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
502 threads simply inherited properties of starting thread instead of
503 setting their own policy and priority
504 - minor fix in our automatic stack trace mechanism on crashes, the
505 main process did not wait for the stack trace process to finish
506 its output
507 - fixed some minor memory leaks
508 - reenabled assembly features support, at the moment only for
509 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
510 - minor assembly fix in x86 features detection (don't use the PIC
511 register, to avoid relocations in the text segment at runtime)
512 - POSIX callback functions of Thread.h are hidden
513
514 * MIDI driver:
515 - dispatch bank select (MSB and LSB) messages
516
517 * audio driver:
518 - the ALSA audio output driver parameters now reflect the correct
519 parameter value ranges for the respective selected sound card
520 (patch by Till Wimmer, a bit fixed and extended)
521
522 * Gigasampler format engine:
523 - if a filter is used and EG2 finishes before EG1, let the voice
524 die when EG2 has finished (this fixes a problem with clicks and
525 voice starvation for some gigs)
526 - playback is no longer disabled during instrument loading
527 - all notes playing on a channel that changes its instrument keep
528 playing with the old instrument until they get a note off
529 command
530 - EG fix: a release value of zero could cause noises or crash
531 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
532 - EG fine tuning: when attack is zero the EG starts at a level
533 above max sustain level, which means that there is a decay phase
534 even if sustain is 100%
535 - more EG fixes: the level could sometimes go below zero and cause
536 noises or crashes
537 - minor fix of EGDecay (patch by Toshi Nagata)
538 - fixed compiler error when --enable-override-filter-type was
539 supplied to the configure script (fixes #46)
540 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
541 instead of a fix value
542 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
543 127 (solo mode) only kill voices if the respective mode really
544 changed
545
546 * LSCP server:
547 - fixed compile time error for old Bison versions
548 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
549 - parser now supports extended ASCII character set
550 (up to ASCII code 255, i.e. includes now umlauts and accents)
551 - filename arguments in LSCP commands now allow to use escape
552 sequences, that is directly literal as one of: \', \", \\, \n, \r,
553 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
554 code value like \xf2) (fixes bug #24)
555 - the following LSCP commands now also support escape sequences for at
556 least one of their text-based parameters (i.e. name, description):
557 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
558 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
559 "SET DB_INSTRUMENT_DIRECTORY NAME",
560 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
561 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
562 "FIND DB_INSTRUMENT_DIRECTORIES"
563 - returns verbose syntax errors (line and column where syntax error
564 occured, the unexpected character and the actually expected, possible
565 character(s), the latter only if less than 5 possibilities)
566 - made sure that LSCP syntax is not affected by gigedit locale
567 settings
568 - bugfix regarding strings parameter lists: all comma separated lists
569 of strings were treated as being one string containing commas
570 (fixes #57)
571
572 * Bug fixes:
573 - fixed crash occurring on certain LSCP scripts (Bug 39)
574 - another thread safety fix for lscp "load engine" and "set
575 channel audio output device"
576 - fixed a crash which occurs when reassigning the same engine
577 on a sampler channel with connected MIDI device
578 - fixed a crash which occurs when changing the number of ports of a MIDI
579 device connected to a sampler channel to number less then or equal
580 to the index of the port to which the sampler channel is connected.
581 - The previous bindings were not been disconnected when altering
582 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
583 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
584 - The active stream/voice count statistic was incorrect.
585 - notification events were not been sent for some sampler
586 channel changes
587 - added default min and max values to restrict the number of allowed
588 audio output channels and MIDI input ports
589 - the connection to the PCM interface is now closed when destroying
590 an audio output device
591 - files with slash in their path or filename could not be loaded
592
593 * test cases:
594 - updated and fixed (haven't been touched in a while)
595
596 Version 0.4.0 (24 November 2006)
597
598 * packaging changes:
599 - changed deprecated copyright attribute to license; added ldconfig
600 to post-(un)install steps; added devel package for liblinuxsampler;
601 to linuxsampler.spec (RPM)
602 - install necessary development header files for allowing 3rd party
603 applications to link against liblinuxsampler
604 - liblinuxsampler's API documentation can be generated with 'make docs'
605 (Doxygen required)
606 - added benchmark to automatically detect the best triangle LFO
607 implementation (currently either an integer math solution or a
608 di-harmonic approximation), automatic detection can be overriden
609 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
610 configure script argument though (mandatory for cross-compilation)
611 - do not automatically pick optimized gcc flags if the user already
612 provided some on his own (as CXXFLAGS)
613 - added compile time option to disable processing of All-Notes-Off MIDI
614 messages
615 - added compile time options to allow disabling the various audio and
616 MIDI drivers
617 - fixed automatic GCC CPU switch detection on PPC
618 (patch by Ebrahim Mayat)
619
620 * Gigasampler format engine:
621 - extensive synthesis optimization
622 (reimplementation of EGs and LFO(s), removed synthesis parameter
623 prerendering and the synthesis parameter matrix in general, splitting
624 each audio fragment into subfragments now where each subfragment uses
625 constant pitch and filter coefficients. The volume coefficient is
626 linearly interpolated inside a subfragment, unless
627 --disable-interpolate-volume is set.)
628 - fine tuning of the EG modulation parameters
629 - improved filter cutoff calculation by adding support for the
630 following gig parameters: Cutoff freq (used when no cutoff
631 controller is defined), Control invert, Minimum cutoff, Velocity
632 curve and Velocity range. The keyboard tracking now scales
633 cutoff frequency instead of resonance.
634 - added support for gig parameter Resonance.
635 - fixed bug in sysex handling (patch by Juan Linietsky)
636 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
637 which can be overridden with --enable-global-attenuation
638 - EG fixes: made the length of "attack hold" stage more
639 accurate. Release stage can now start before attack stage
640 ends. Cancel release didn't work when sustain was zero. Attack
641 time now has a minimal value to prevent clicks.
642 - fixed pitch changes larger than one octave
643 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
644 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
645 all modes can be altered via standard GM messages, that is CC5 for
646 altering portamento time, CC65 for enabling / disabling portamento
647 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
648 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
649 parameter) and crossfade
650 - added support for the "attenuation controller threshold" gig
651 parameter
652 - added smoothing of volume changes caused by control change
653 messages
654 - sample loop parameters are now taken from the DimensionRegion
655 instead of the wave chunk
656 - fixed keyswitching for v3 gigs with a number of keyswitch splits
657 not equal to a power of two
658 - reimplementation of the filter algorithm. The new filter is more
659 accurate and supports all gig filter types, including bandreject
660 and lowpass turbo.
661 - real support for 24 bit samples - samples are not truncated to
662 16 bits anymore
663 - support for aftertouch (channel pressure, not polyphonic
664 aftertouch)
665 - LFO1 behaviour fixed (dampening from max volume instead of
666 amplifying from 0)
667
668 * LSCP server:
669 - fixed application exit on broken pipe error (fixes bug #20)
670 - fixed the notification messages delay due to lack of
671 network activity (fixes bug #26)
672 - fixed parser bug which occured on space(s) within device parameters
673 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
674
675 * audio driver:
676 - added aRts audio output driver (by no means RT safe)
677
678 * MIDI driver:
679 - fixed legacy sysex code which caused dispatching of MIDI SysEx
680 messages several times instead of once
681 - API extension for MIDI drivers which already supply exact time stamps
682 for events (i.e. for offline rendering based MIDI drivers)
683 - added checks for bad MIDI data
684
685 * linuxsampler application:
686 - show available sampler engine types on startup
687
688 * general changes:
689 - support for muting sampler channels and solo mode of the same, two new
690 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
691 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
692 introduced for this, the behavior is the same like on a mixer console
693 (patch by Grigor Iliev, a bit adjusted). Also added configure option
694 --enable-process-muted-channels which can be used to enable the
695 processing of muted channels.
696 - support for sostenuto pedal
697 - support for monitoring the total number of active voices
698 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
699 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
700 - fixed some memory management errors
701 - fixed some concurrency problems that could lead to crashes when
702 LSCP commands were executed
703 - fixed crash when instrument loading failed previously on the same
704 sampler channel (fixes bug #36)
705
706 Version 0.3.3 (15 July 2005)
707
708 * packaging changes:
709 - fixed compilation with gcc 4.0
710
711 * Gigasampler format engine:
712 - LFO preprocessing was performed even though the respective LFO was
713 disabled by the instrument patch (minor efficiency fix)
714 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
715 for volume ramp downs in the same fragment (needed for current voice
716 stealing implementation) then simply inform the user with a warning
717 about possible click sounds and reduce the volume ramp down
718 appropriately instead of cancelling the audio device connection
719
720 Version 0.3.2 (24 June 2005)
721
722 * packaging changes:
723 - updated autotools build files to compile on OS X
724 (conditional compilation of CoreMIDI and MidiShare drivers)
725 - hand-crafted assembly optimization code can be disabled with
726 './configure --disable-asm' (definitely not recommended)
727 - fixed 'make dist' rule to include all necessary files
728 - require automake (>= 1.5) for 'make -f Makefile.cvs'
729 (due to 'dist-bzip2' automake option)
730
731 * Gigasampler format engine:
732 - support for the gig parameters for "release velocity response" curves
733 - fine tuning of the EGADSR envelope
734 - volume of release triggered samples now depends on note-on velocity,
735 note length and gig parameter "release trigger decay" instead of
736 note-off velocity.
737 - revised voice stealing
738 (fixes crash and endless loop caused by voice stealing)
739 - don't reset scale tuning on instrument or audio output device change
740 - handle key group conflicts right at the beginning of each fragment
741 instead of when the respective voice is actually launched
742 (fixes undefined behavior if stolen voices belonged to a key group -
743 this case was followed by a "killed voice survived" error message)
744 - fixed minor issue with null/silence samples
745 (those stole voices even though they don't need a voice at all which
746 resulted in "voice stealing didn't work out" messages)
747 - don't reset volume, pan, pitch and MIDI controller values on
748 instrument or audio output device change
749
750 * LSCP server:
751 - fixed some crashes (patch by Grigor Iliev, fixes #19)
752 - fixed LSCP event "CHANNEL_INFO" notification
753 (e.g. did not notify on volume changes or MIDI program change events)
754
755 * linuxsampler application:
756 - added command line parameters --lscp-addr and --lscp-port to override
757 default IP address and port of LSCP server
758
759 Version 0.3.1 (24 May 2005)
760
761 * initial release
