Sat Sep 18 09:24:41 2010 UTC (9 years, 1 month ago) by schoenebeck
File size: 35385 byte(s)
* implemented support for internal LADSPA effects (work in progress)

1 Version CVS HEAD (?)
2
3 * packaging changes:
4 - fixed building with newer MinGW-w64
5
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
27 * Gigasampler format engine:
28 - implemented the "round robin keyboard" dimension
29 - fixed round robin and random dimensions for cases when number of
30 dimension zones is not a power of two
31 - made round robin use a counter for each region instead of each
32 key
33
34 * SFZ format engine:
35 - Initial implementation (not usable yet)
36 - added support for v2 multiple stage envelope generators
37 - added a fine-tuned v1 envelope generator instead of using the
38 one from the gig engine
39 - fixed memory leak and memory handling errors
40 - added support for trigger=first, trigger=legato and sw_previous
41 - allow non-numerical key values ("C#4" for example)
42 - "key" opcode now sets pitch_keycenter too
43 - fixed error when unloading instrument with same sample used by
44 multiple regions
45 - added some opcode aliases, like loopmode for loop_mode, to be
46 more compatible
47 - added support for trigger=release and rt_decay
48 - added support for off_mode=normal
49 - added support for random, seq_position, seq_length and volume
50 - added v1 LFO opcodes to parser (no support in engine yet)
51 - added support for amp_veltrack and amp_velcurve_N
52 - fine-tuned the default velocity curve
53 - added support for transpose
54 - fixed crash when using sw_down/up
55 - improved logic for sw_lokey/hikey/up/down/last
56 - added more v1 aliases to parser
57 - reduced memory usage for sfz data
58 - RT-safeness: avoid malloc in audio thread
59 - fixed a bug that could cause voice stealing to fail
60 - optimized sample lookup
61 - improved support for exclusive groups (group, off_by and
62 off_mode)
63 - added support for controller triggered regions (on_locc/on_hicc)
64 - added support for loop_mode=one_shot
65 - fixed playback of 16 bit wav files on big endian CPUs
66 - added support for Ogg Vorbis sample files
67
68 * SoundFont format engine:
69 - Initial implementation (not usable yet)
70 - RT-safeness: avoid malloc in audio thread
71 - fixed a bug that could cause voice stealing to fail
72
73 * Host plugins:
74 - AU bugfix: failed to destroy its audio/MIDI devices
75 - Listen to all interfaces on Mac OS X (INADDR_ANY)
76 - VST bugfix: If the host called resume() before and after
77 changing sample rate or block size, the number of channels was
78 incorrectly set to two. This caused silence in Cubase 5.
79
80 * MIDI driver:
81 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
82 the ALSA sequencer client name
83
84 * LSCP server:
85 - added support for sending MIDI CC messages via LSCP command
86 "SEND CHANNEL MIDI_DATA CC <sampler-chan> <ctrl> <val>"
87
88 * Bug fixes:
89 - Fixed crash which may occur when MIDI key + transpose is out of range
90 - minor valgrind fixes
91 - fixed crash which occured when changing an already deployed sampler
92 channel to a different engine type
93
94 Version 1.0.0 (31 July 2009)
95
96 * packaging changes:
97 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
98 causing e.g. the libgig test to fail when
99 "./configure --disable-jack-driver" was used
100 (patch by Alexis Ballier)
101 - fixed compilation with gcc 4.3
102 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
103 - fixed configure so it detects x86_64 (#107)
104 - fixes for building with newer MinGW versions
105 - fix for building with bison 2.4 (#111)
106 - fixed building with libgig installed in a non-standard directory
107 - minor fix in configure for mmsystem.h detection on MinGW
108 - Windows: look for editor plugins and Fantasia using base
109 directory of liblinuxsampler dll (look in the same directory and one
110 directory above)
111 - configure script fix: removed unconditional use of SSE
112 - fixed building with sqlite installed in a non-standard directory
113 - when cross-compiling, don't try to create instruments.db
114 - fix for new mingw-w64 version, which has usleep
115
116 * general changes:
117 - bugfix: on some POSIX systems instrument editor plugins refused to
118 load as we used a non-portable Linux specific struct field
119 (fixes bug #70, patch by Ronald Baljeu)
120 - fixed endless loop which occured when loading an instrument editor
121 plugin DLL on Windows systems failed
122 - fixed memory leaks that occurred when liblinuxsampler was unloaded
123 - optimized the SynchronizedConfig class so it doesn't wait
124 unnecessarily long after an update
125 - added support for notifying instrument editors on note-on / note-off
126 events (e.g. to highlight the pressed keys on the virtual keyboard
127 of gigedit)
128 - added support for triggering notes by instrument editors (see above)
129 - be verbose on DLL load errors (on Linux)
130 - fixed di-harmonic triangle LFO implementation (this LFO implementation
131 is only used by very few systems, most pick the int math
132 implementation, which is usually faster)
133 - fixes for audio drivers with varying buffer sizes
134 - experimental support for running LinuxSampler as a DSSI, LV2 and
135 VST plugin
136 - notification events for stream/voice count statistics are now sent
137 only when there are actual changes
138 - added memory ordering constraints to improve stability on
139 multi-core and multi-cpu systems
140 - maximum voices and disk streams can now be altered at runtime
141 - fixed CPU feature detection on x86_64 (maybe fixes #108)
142 - automatic stacktrace mechanism is now turned off by default and can
143 be switched on by command line option "--stacktrace" (the automatic
144 stacktrace mechanism seems to be broken on most systems at the moment)
145 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
146 a pointer to the launched InstrumentEditor object
147 - added optional 3rd party user data parameter for following
148 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
149 InstrumentEditor::Launch(),
150 InstrumentManager::LaunchInstrumentEditor()
151 - theoretical fix: made SynchronizedConfig follow C++0x memory
152 model more strictly
153 - fixes for using large audio device buffers
154 - Windows: add the installation directory to the DLL search path
155 when loading an editor plugin (solves problems with VST and
156 gigedit on systems with other GTK versions installed)
157
158 * audio driver:
159 - removed the nonsense audio channel constraint (which was hard coded to
160 max. 100 audio channels) for most audio drivers
161 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
162 opposed to the LSCP specs
163 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
164 reflected the wrong value
165 - fixed a memory management bug in ASIO driver
166 - Makefile fix: JACK_CFLAGS wasn't used
167 - JACK: use jack_client_open instead of the deprecated
168 jack_client_new
169 - added (experimental) CoreAudio driver
170 - applied old fixes to the ASIO driver that were included in the
171 previous binary release but accidentally never committed to CVS
172 (fixes #117)
173 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
174 win64)
175 - VST: added support for sample rate and buffer size changes
176 - VST: close editor (Fantasia) when the VST is removed
177 - VST: avoid opening Fantasia more than once for each VST instance
178 - VST: export main function as "main" on Linux too (fix for
179 energyXT)
180 - VST: changed number of output channels from one stereo to 16
181 stereo
182 - added channel routing, fxsends and midi maps to the settings
183 stored in the plugin state
184 - performance optimization of AudioChannel::MixTo() and
185 AudioChannel::CopyTo() methods using GCC vector exensions
186 (if available)
187 - ASIO fixes: avoid initializing the device twice, avoid throwing
188 exception when getting parameters from a disconnected device
189
190 * MIDI driver:
191 - added JACK MIDI driver
192 - dispatch bank select as ordinary CC as well, the user might seriously
193 want to (mis)use it for some purpose ("fixed" in all current MIDI
194 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
195 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
196 CoreMidi or AU
197 - fixed mingw-w64 compilation error in MME driver
198 - made program change handling in MIDI thread real-time safe by
199 moving the logic to a non-RT thread
200 - fixed minor memory leak in ALSA driver
201
202 * instruments database:
203 - avoid time consuming samples scanning when adding instruments
204 to the instruments database
205 - added support for handling lost files in the instruments database
206 - Implemented option for adding instruments in separate directories
207 in the instruments database
208 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
209 - work-around for missing fnmatch function on Windows to make
210 instrument database compilable
211 - added instrument database support on Windows
212 works with both standalone mode and VST plugin.
213 the instruments DB file is located in
214 %USERPROFILE%\.linuxsampler\instruments.db which allows different
215 databases for each windows user
216 if no DB is present it automatically creates the .linuxsampler subdir
217 and then creates an empty DB
218 - fixed recursive import, which was broken on Windows
219
220 * Gigasampler format engine:
221 - fixed a memory leak that could happen when a channel was deleted
222 while notes were playing
223 - made it possible to load an instrument even if the audio thread
224 isn't running
225 - added partial support for the "Controller Triggered" MIDI rule,
226 enough for piano gigs with pedal noise samples
227 - minor fix: only mark FX sends as being modified if really the
228 respective FX send MIDI controller was used
229 - added support for GM global device volume SysEx message
230 (can be selected at compile time to either apply globally to the
231 whole sampler [default] or only to the sampler channels that are
232 connected to the respective MIDI input port the SysEx message arrived
233 on)
234 - bugfix: notes triggered at position 0 in the audio buffer were
235 sometimes wrongly killed in the same buffer, causing no sound to
236 be played
237 - added support for chromatic / drumkit mode Roland GS Sysex message
238 which is usally used to switch a part between chromatic sounds and
239 drumkit sounds (as opposed to their common default setting of MIDI
240 part 10 being a drumkit part and all other ones chromatic parts), in
241 LS however one can switch between the first 16 MIDI instrument maps
242 defined for the sampler
243 - made it possible to create multiple sample channels even if the
244 audio thread isn't running
245 - fixed crash when removing channel with active voices (#116)
246 - bugfix: on sample reference changes (instrument editor), only
247 un-cache the respective sample if it's really not used by any
248 sampler engine anymore
249 - re-cache samples in case they were changed by an instrument editor,
250 e.g. when a sample was added while playing (#82)
251 - fixed hanging notes which occured when note-off event had the exact
252 same time stamp as the voice's note-on event and occured both in the
253 same audio fragment cycle (fixes bug #112)
254 - added support for the "fine tune" and "pitch bend range"
255 instrument-level gig parameters
256 - fixed minor artifacts in pitch bend handling
257 - added support for GS Reset SysEx message
258 - allow gig files to use unlimited downward pitch shifting
259 - added a limit check for upward pitch shifting
260 - bugfix: sometimes, when playing a note twice fast, the second
261 note was silent
262 - fixed crash happening when a pitch bend event arrived at the
263 same time a new instrument was loading
264
265 * LSCP server:
266 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
267 react on MIDI data arriving on certain sampler channels (so far only
268 Note-On and Note-Off events are sent via this LSCP event)
269 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
270 react on MIDI data arriving on certain MIDI input devices (so far only
271 Note-On and Note-Off events are sent via this LSCP event)
272 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
273 SET DB_INSTRUMENT FILE_PATH
274 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
275 frontends to send MIDI messages to specific sampler channel
276 - added two additional fields to GET FILE INSTRUMENT INFO command -
277 KEY_BINDINGS and KEYSWITCH_BINDINGS
278 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
279 was incorrect
280 - Optimized the retrieval of the MIDI instrument mappings
281 - added new LSCP command "SET VOICES" to globally alter the maximum
282 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
283 be triggered respectively
284 - added new LSCP command "SET STREAMS" to globally alter the maximum
285 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
286 which will be triggered respectively
287 - bugfix: retry if "select" returns EINTR (this fixes a crash when
288 a gigedit file dialog is opened)
289 - close all connections when LSCPServer is deleted
290 - hard close of all sockets on exit
291 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
292 driver
293
294 * Bug fixes:
295 - fixed a crash which occurs when removing a sampler channel waiting
296 to start instrument loading after another channel
297 - fixed a crash which occurs when removing a sampler channel with
298 instrument loading in progress (bug #113)
299 - fixed termination caused by uncaught exception when adding MIDI
300 instrument with PERSISTENT load mode
301 - fixed possible iterator invalidations when resetting the sampler
302 - fixed memory leaks when issuing the following LSCP commands:
303 GET AUDIO_OUTPUT_DRIVER INFO
304 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
305 GET MIDI_INPUT_DRIVER INFO
306 GET MIDI_INPUT_DRIVER_PARAMETER INFO
307 - fixed possible compilation error when sqlite is not present
308 - fixed orphaned pointers when setting maximum voices limit (bug #118)
309 - fixed crash when changing the audio output device of a sampler
310 channel with loaded instrument and start playing notes
311 - fixed endless loop in Engine::SuspendAll() (bug #120)
312 - fixed a low-level atomic load function that was broken on 64-bit
313 PowerPC, which probably could cause crashes on that platform
314 - fixed a memory management error which could cause a crash when a
315 plugin was unloaded
316 - bugfix: two private structs had the same name, which could cause
317 problems if the linker chose the wrong constructor
318 - fixed low-level ConditionServer usage bug that caused lockups on
319 Windows
320
321
322 Version 0.5.1 (6 December 2007)
323
324 * packaging changes:
325 - added autoconf checks for pthread library
326 - added autoconf check for pthread bug found on certain NPTL-enabled
327 glibc versions (see Gentoo bug report #194076)
328 - added autoconf checks for MS Windows
329
330 * general changes:
331 - bugfix: the thread used by an editor plugin didn't die when the
332 editor closed
333 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
334 out all the space. operator--() did not apply size_mask after
335 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
336 order to avoid problems with the _NonVolatileReader functions.
337 - bugfix: Stream.h: added a missing divide by BytesPerSample in
338 GetWriteSpace(). Since this function is currently only used in
339 the stream's qsort() compare function, it didn't trigger any
340 bugs.
341 - Resampler.h, Synthesizer.h: cubic interpolation now works in
342 24bit mode too. Faster method to read 24bit words on little
343 endian machines (x86): replaced 3 byte reads + shifts with a 1
344 unaligned 32bit read and shift
345 - experimental support for MS Windows (MIDI input via MME, AUDIO
346 output via ASIO)
347 - made handling of SIGINT signal (Ctrl-C) a bit more robust
348 - support for monitoring the total number of active disk streams
349 (new LSCP commands: GET TOTAL_STREAM_COUNT,
350 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
351
352 * AUDIO driver:
353 - added Windows ASIO low latency audio driver
354
355 * MIDI driver:
356 - added MME Windows MIDI driver
357
358 * LSCP server:
359 - added support for Windows style path / filenames, however with
360 forward slash path separators instead of backslash
361 (i.e. "C:/foo/bar.gig")
362 - allow naughty liblscp to send non-string device parameters within
363 apostrophes as well
364 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
365 "LIST FILE INSTRUMENTS <file>" and
366 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
367 about an arbitrary instrument file on the system where the sampler is
368 running on
369
370 Version 0.5.0 (15 October 2007)
371
372 * packaging changes:
373 - config.h is not going to be installed along with liblinuxsampler's
374 API header files anymore
375 - only the API relevant header (and source) files will be exported to
376 the Doxygen API documentation (explicitly listed in Doxyfile.in)
377 - added completely new XCode project files for Mac OSX which is now
378 capable to execute our autoconf environment, thus no need anymore
379 to maintain the compile time configuration file (osx/version.h) for
380 OSX manually (patch by Toshi Nagata)
381 - fixed buggy boolean --enable-foo / --disable-foo configure script
382 parameters
383 - global.h now only covers global definitions that are needed for the
384 C++ API header files, all implementation internal global definitions
385 are now in global_private.h
386 - atomic.h is not exposed to the C++ API anymore
387 - no need to include config.h anymore for using LS's API header files
388 - fixed warnings in API doc generation
389
390 * general changes:
391 - replaced the old, confusing MIDI program change mechanism by a
392 flexible MIDI instrument mapper which allows to map arbitrary
393 (MIDI bank, MIDI program) pairs with arbitrary
394 (engine type, instrument file, file index) triplets which will be
395 loaded on the respective channel when such MIDI program change
396 messages arrive, beside that, each entry allows to define a life-time
397 strategy for the instrument, so the user can define whether the
398 instrument should i.e. be permanently loaded (to be able to switch
399 quickly among sounds) or i.e. loaded just on demand when the
400 respective program change arrives (to safe RAM space), as well as a
401 global volume factor for each entry, so the user can adjust the volume
402 dynamic of his mapped instrument collection without having to modify
403 the instrument files, also one can manage arbitrary amount of such
404 MIDI instrument maps and assign each sampler channel individually
405 a certain map, so that i.e. separation of normal instruments and
406 drumkits is possible
407 - new notification events for tracking changes to audio/MIDI devices,
408 MIDI instrument maps, MIDI instruments, FX sends, global volume.
409 - sampler was limited to load max. 200 instruments in the background
410 due to a constant size RingBuffer FIFO which is now replaced by a
411 dynamic (unlimited) size std::list FIFO
412 - added FX sends, these allow to route audio signals to arbitrary audio
413 output channels for being processed by external effect processors
414 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
415 controllers
416 - global (sampler wide) volume can now be controlled at runtime
417 - Implemented new, improved notification system
418 - fixed compilation errors regarding OSX
419 (patch by Toshi Nagata)
420 - implemented instruments database
421 - added support for escape sequences to the instruments database
422 - added highly experimental support for on-the-fly instrument editing
423 within the sampler's process (by using instrument editor plugins),
424 you'll notice the new "Registered instrument editors:" message on
425 startup, added a new LSCP command:
426 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
427 to spawn a matching instrument editor for the instrument on the
428 given sampler channel, the plugin path can be overridden at compile
429 time with ./configure --enable-plugin-dir=/some/dir
430 - added experimental code for synchronizing instrument editors hosted
431 in the sampler's process to safely edit instruments while playing
432 without a crash (hopefully) by either suspending single regions
433 wherever possible or if unavoidable whole engine(s)
434 - fixed several issues in fundamental "Thread" class: set scheduling
435 policy and priority on thread level, set a minimum stack size for
436 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
437 threads simply inherited properties of starting thread instead of
438 setting their own policy and priority
439 - minor fix in our automatic stack trace mechanism on crashes, the
440 main process did not wait for the stack trace process to finish
441 its output
442 - fixed some minor memory leaks
443 - reenabled assembly features support, at the moment only for
444 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
445 - minor assembly fix in x86 features detection (don't use the PIC
446 register, to avoid relocations in the text segment at runtime)
447 - POSIX callback functions of Thread.h are hidden
448
449 * MIDI driver:
450 - dispatch bank select (MSB and LSB) messages
451
452 * audio driver:
453 - the ALSA audio output driver parameters now reflect the correct
454 parameter value ranges for the respective selected sound card
455 (patch by Till Wimmer, a bit fixed and extended)
456
457 * Gigasampler format engine:
458 - if a filter is used and EG2 finishes before EG1, let the voice
459 die when EG2 has finished (this fixes a problem with clicks and
460 voice starvation for some gigs)
461 - playback is no longer disabled during instrument loading
462 - all notes playing on a channel that changes its instrument keep
463 playing with the old instrument until they get a note off
464 command
465 - EG fix: a release value of zero could cause noises or crash
466 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
467 - EG fine tuning: when attack is zero the EG starts at a level
468 above max sustain level, which means that there is a decay phase
469 even if sustain is 100%
470 - more EG fixes: the level could sometimes go below zero and cause
471 noises or crashes
472 - minor fix of EGDecay (patch by Toshi Nagata)
473 - fixed compiler error when --enable-override-filter-type was
474 supplied to the configure script (fixes #46)
475 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
476 instead of a fix value
477 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
478 127 (solo mode) only kill voices if the respective mode really
479 changed
480
481 * LSCP server:
482 - fixed compile time error for old Bison versions
483 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
484 - parser now supports extended ASCII character set
485 (up to ASCII code 255, i.e. includes now umlauts and accents)
486 - filename arguments in LSCP commands now allow to use escape
487 sequences, that is directly literal as one of: \', \", \\, \n, \r,
488 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
489 code value like \xf2) (fixes bug #24)
490 - the following LSCP commands now also support escape sequences for at
491 least one of their text-based parameters (i.e. name, description):
492 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
493 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
494 "SET DB_INSTRUMENT_DIRECTORY NAME",
495 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
496 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
497 "FIND DB_INSTRUMENT_DIRECTORIES"
498 - returns verbose syntax errors (line and column where syntax error
499 occured, the unexpected character and the actually expected, possible
500 character(s), the latter only if less than 5 possibilities)
501 - made sure that LSCP syntax is not affected by gigedit locale
502 settings
503 - bugfix regarding strings parameter lists: all comma separated lists
504 of strings were treated as being one string containing commas
505 (fixes #57)
506
507 * Bug fixes:
508 - fixed crash occurring on certain LSCP scripts (Bug 39)
509 - another thread safety fix for lscp "load engine" and "set
510 channel audio output device"
511 - fixed a crash which occurs when reassigning the same engine
512 on a sampler channel with connected MIDI device
513 - fixed a crash which occurs when changing the number of ports of a MIDI
514 device connected to a sampler channel to number less then or equal
515 to the index of the port to which the sampler channel is connected.
516 - The previous bindings were not been disconnected when altering
517 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
518 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
519 - The active stream/voice count statistic was incorrect.
520 - notification events were not been sent for some sampler
521 channel changes
522 - added default min and max values to restrict the number of allowed
523 audio output channels and MIDI input ports
524 - the connection to the PCM interface is now closed when destroying
525 an audio output device
526 - files with slash in their path or filename could not be loaded
527
528 * test cases:
529 - updated and fixed (haven't been touched in a while)
530
531 Version 0.4.0 (24 November 2006)
532
533 * packaging changes:
534 - changed deprecated copyright attribute to license; added ldconfig
535 to post-(un)install steps; added devel package for liblinuxsampler;
536 to linuxsampler.spec (RPM)
537 - install necessary development header files for allowing 3rd party
538 applications to link against liblinuxsampler
539 - liblinuxsampler's API documentation can be generated with 'make docs'
540 (Doxygen required)
541 - added benchmark to automatically detect the best triangle LFO
542 implementation (currently either an integer math solution or a
543 di-harmonic approximation), automatic detection can be overriden
544 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
545 configure script argument though (mandatory for cross-compilation)
546 - do not automatically pick optimized gcc flags if the user already
547 provided some on his own (as CXXFLAGS)
548 - added compile time option to disable processing of All-Notes-Off MIDI
549 messages
550 - added compile time options to allow disabling the various audio and
551 MIDI drivers
552 - fixed automatic GCC CPU switch detection on PPC
553 (patch by Ebrahim Mayat)
554
555 * Gigasampler format engine:
556 - extensive synthesis optimization
557 (reimplementation of EGs and LFO(s), removed synthesis parameter
558 prerendering and the synthesis parameter matrix in general, splitting
559 each audio fragment into subfragments now where each subfragment uses
560 constant pitch and filter coefficients. The volume coefficient is
561 linearly interpolated inside a subfragment, unless
562 --disable-interpolate-volume is set.)
563 - fine tuning of the EG modulation parameters
564 - improved filter cutoff calculation by adding support for the
565 following gig parameters: Cutoff freq (used when no cutoff
566 controller is defined), Control invert, Minimum cutoff, Velocity
567 curve and Velocity range. The keyboard tracking now scales
568 cutoff frequency instead of resonance.
569 - added support for gig parameter Resonance.
570 - fixed bug in sysex handling (patch by Juan Linietsky)
571 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
572 which can be overridden with --enable-global-attenuation
573 - EG fixes: made the length of "attack hold" stage more
574 accurate. Release stage can now start before attack stage
575 ends. Cancel release didn't work when sustain was zero. Attack
576 time now has a minimal value to prevent clicks.
577 - fixed pitch changes larger than one octave
578 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
579 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
580 all modes can be altered via standard GM messages, that is CC5 for
581 altering portamento time, CC65 for enabling / disabling portamento
582 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
583 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
584 parameter) and crossfade
585 - added support for the "attenuation controller threshold" gig
586 parameter
587 - added smoothing of volume changes caused by control change
588 messages
589 - sample loop parameters are now taken from the DimensionRegion
590 instead of the wave chunk
591 - fixed keyswitching for v3 gigs with a number of keyswitch splits
592 not equal to a power of two
593 - reimplementation of the filter algorithm. The new filter is more
594 accurate and supports all gig filter types, including bandreject
595 and lowpass turbo.
596 - real support for 24 bit samples - samples are not truncated to
597 16 bits anymore
598 - support for aftertouch (channel pressure, not polyphonic
599 aftertouch)
600 - LFO1 behaviour fixed (dampening from max volume instead of
601 amplifying from 0)
602
603 * LSCP server:
604 - fixed application exit on broken pipe error (fixes bug #20)
605 - fixed the notification messages delay due to lack of
606 network activity (fixes bug #26)
607 - fixed parser bug which occured on space(s) within device parameters
608 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
609
610 * audio driver:
611 - added aRts audio output driver (by no means RT safe)
612
613 * MIDI driver:
614 - fixed legacy sysex code which caused dispatching of MIDI SysEx
615 messages several times instead of once
616 - API extension for MIDI drivers which already supply exact time stamps
617 for events (i.e. for offline rendering based MIDI drivers)
618 - added checks for bad MIDI data
619
620 * linuxsampler application:
621 - show available sampler engine types on startup
622
623 * general changes:
624 - support for muting sampler channels and solo mode of the same, two new
625 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
626 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
627 introduced for this, the behavior is the same like on a mixer console
628 (patch by Grigor Iliev, a bit adjusted). Also added configure option
629 --enable-process-muted-channels which can be used to enable the
630 processing of muted channels.
631 - support for sostenuto pedal
632 - support for monitoring the total number of active voices
633 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
634 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
635 - fixed some memory management errors
636 - fixed some concurrency problems that could lead to crashes when
637 LSCP commands were executed
638 - fixed crash when instrument loading failed previously on the same
639 sampler channel (fixes bug #36)
640
641 Version 0.3.3 (15 July 2005)
642
643 * packaging changes:
644 - fixed compilation with gcc 4.0
645
646 * Gigasampler format engine:
647 - LFO preprocessing was performed even though the respective LFO was
648 disabled by the instrument patch (minor efficiency fix)
649 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
650 for volume ramp downs in the same fragment (needed for current voice
651 stealing implementation) then simply inform the user with a warning
652 about possible click sounds and reduce the volume ramp down
653 appropriately instead of cancelling the audio device connection
654
655 Version 0.3.2 (24 June 2005)
656
657 * packaging changes:
658 - updated autotools build files to compile on OS X
659 (conditional compilation of CoreMIDI and MidiShare drivers)
660 - hand-crafted assembly optimization code can be disabled with
661 './configure --disable-asm' (definitely not recommended)
662 - fixed 'make dist' rule to include all necessary files
663 - require automake (>= 1.5) for 'make -f Makefile.cvs'
664 (due to 'dist-bzip2' automake option)
665
666 * Gigasampler format engine:
667 - support for the gig parameters for "release velocity response" curves
668 - fine tuning of the EGADSR envelope
669 - volume of release triggered samples now depends on note-on velocity,
670 note length and gig parameter "release trigger decay" instead of
671 note-off velocity.
672 - revised voice stealing
673 (fixes crash and endless loop caused by voice stealing)
674 - don't reset scale tuning on instrument or audio output device change
675 - handle key group conflicts right at the beginning of each fragment
676 instead of when the respective voice is actually launched
677 (fixes undefined behavior if stolen voices belonged to a key group -
678 this case was followed by a "killed voice survived" error message)
679 - fixed minor issue with null/silence samples
680 (those stole voices even though they don't need a voice at all which
681 resulted in "voice stealing didn't work out" messages)
682 - don't reset volume, pan, pitch and MIDI controller values on
683 instrument or audio output device change
684
685 * LSCP server:
686 - fixed some crashes (patch by Grigor Iliev, fixes #19)
687 - fixed LSCP event "CHANNEL_INFO" notification
688 (e.g. did not notify on volume changes or MIDI program change events)
689
690 * linuxsampler application:
691 - added command line parameters --lscp-addr and --lscp-port to override
692 default IP address and port of LSCP server
693
694 Version 0.3.1 (24 May 2005)
695
696 * initial release
