File size: 37812 byte(s)
* bugfix: calling SET VOICES (which Fantasia does on start and
  refresh) could cause instruments to be unloaded
* plugins: save engine type (gig, sfz or sf2) in plugin state
* VST: when opening Fantasia, look for both 32 and 64 bit Java on
  64 bit Windows

1 Version CVS HEAD (?)
3 * packaging changes:
4 - fixed building with newer MinGW-w64
6 * general changes:
7 - Refactoring: moved the independent code from
8 the Gigasampler format engine to base classes
9 - command line option '--profile' is currently disabled, since the
10 respective profiling code is currently broken
11 - Introduced support for optional environment variable
12 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
13 where the sampler shall look for instrument editor plugins
14 (patch by Luis Garrido, slightly modified).
15 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
16 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
17 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
18 note (in this implementation of the sampler its simply hard routed to
19 the 1st effect send of the sampler channel, no matter what the actual
20 effect type is)
21 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
22 note (in this implementation of the sampler its simply hard routed to
23 the 2nd effect send of the sampler channel, no matter what the actual
24 effect type is)
25 - implemented support for internal LADSPA effects
26 - raised limit of program change queue from 100 to 512
27 (as suggested by Alex Stone)
29 * Gigasampler format engine:
30 - implemented the "round robin keyboard" dimension
31 - fixed round robin and random dimensions for cases when number of
32 dimension zones is not a power of two
33 - made round robin use a counter for each region instead of each
34 key
36 * SFZ format engine:
37 - Initial implementation (not usable yet)
38 - added support for v2 multiple stage envelope generators
39 - added a fine-tuned v1 envelope generator instead of using the
40 one from the gig engine
41 - fixed memory leak and memory handling errors
42 - added support for trigger=first, trigger=legato and sw_previous
43 - allow non-numerical key values ("C#4" for example)
44 - "key" opcode now sets pitch_keycenter too
45 - fixed error when unloading instrument with same sample used by
46 multiple regions
47 - added some opcode aliases, like loopmode for loop_mode, to be
48 more compatible
49 - added support for trigger=release and rt_decay
50 - added support for off_mode=normal
51 - added support for random, seq_position, seq_length and volume
52 - added v1 LFO opcodes to parser (no support in engine yet)
53 - added support for amp_veltrack and amp_velcurve_N
54 - fine-tuned the default velocity curve
55 - added support for transpose
56 - fixed crash when using sw_down/up
57 - improved logic for sw_lokey/hikey/up/down/last
58 - added more v1 aliases to parser
59 - reduced memory usage for sfz data
60 - RT-safeness: avoid malloc in audio thread
61 - fixed a bug that could cause voice stealing to fail
62 - optimized sample lookup
63 - improved support for exclusive groups (group, off_by and
64 off_mode)
65 - added support for controller triggered regions (on_locc/on_hicc)
66 - added support for loop_mode=one_shot
67 - fixed playback of 16 bit wav files on big endian CPUs
68 - added support for Ogg Vorbis sample files
70 * SoundFont format engine:
71 - Initial implementation (not usable yet)
72 - RT-safeness: avoid malloc in audio thread
73 - fixed a bug that could cause voice stealing to fail
75 * Host plugins:
76 - AU bugfix: failed to destroy its audio/MIDI devices
77 - Listen to all interfaces on Mac OS X (INADDR_ANY)
78 - VST bugfix: If the host called resume() before and after
79 changing sample rate or block size, the number of channels was
80 incorrectly set to two. This caused silence in Cubase 5.
81 - save engine type (gig, sfz or sf2) in plugin state
82 - VST: when opening Fantasia, look for both 32 and 64 bit Java on
83 64 bit Windows
85 * MIDI driver:
86 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
87 the ALSA sequencer client name
88 - removed limit of maximum amount of MIDI ports per MIDI device, since
89 there is no reason for this limit
91 * LSCP server:

111 - added LSCP command
112 "REMOVE SEND_EFFECT_CHAIN <audio-device> <effect-chain>"
113 - added LSCP command
114 "GET SEND_EFFECT_CHAIN INFO <audio-device> <effect-chain>"

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