* fixed crash when deleting a sampler channel or changing engine type
  while an instrument load was 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 - fixed crash when deleting a sampler channel or changing engine
94 type while an instrument load was in progress
95
96 Version 1.0.0 (31 July 2009)
97
98 * packaging changes:
99 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
100 causing e.g. the libgig test to fail when
101 "./configure --disable-jack-driver" was used
102 (patch by Alexis Ballier)
103 - fixed compilation with gcc 4.3
104 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
105 - fixed configure so it detects x86_64 (#107)
106 - fixes for building with newer MinGW versions
107 - fix for building with bison 2.4 (#111)
108 - fixed building with libgig installed in a non-standard directory
109 - minor fix in configure for mmsystem.h detection on MinGW
110 - Windows: look for editor plugins and Fantasia using base
111 directory of liblinuxsampler dll (look in the same directory and one
112 directory above)
113 - configure script fix: removed unconditional use of SSE
114 - fixed building with sqlite installed in a non-standard directory
115 - when cross-compiling, don't try to create instruments.db
116 - fix for new mingw-w64 version, which has usleep
117
118 * general changes:
119 - bugfix: on some POSIX systems instrument editor plugins refused to
120 load as we used a non-portable Linux specific struct field
121 (fixes bug #70, patch by Ronald Baljeu)
122 - fixed endless loop which occured when loading an instrument editor
123 plugin DLL on Windows systems failed
124 - fixed memory leaks that occurred when liblinuxsampler was unloaded
125 - optimized the SynchronizedConfig class so it doesn't wait
126 unnecessarily long after an update
127 - added support for notifying instrument editors on note-on / note-off
128 events (e.g. to highlight the pressed keys on the virtual keyboard
129 of gigedit)
130 - added support for triggering notes by instrument editors (see above)
131 - be verbose on DLL load errors (on Linux)
132 - fixed di-harmonic triangle LFO implementation (this LFO implementation
133 is only used by very few systems, most pick the int math
134 implementation, which is usually faster)
135 - fixes for audio drivers with varying buffer sizes
136 - experimental support for running LinuxSampler as a DSSI, LV2 and
137 VST plugin
138 - notification events for stream/voice count statistics are now sent
139 only when there are actual changes
140 - added memory ordering constraints to improve stability on
141 multi-core and multi-cpu systems
142 - maximum voices and disk streams can now be altered at runtime
143 - fixed CPU feature detection on x86_64 (maybe fixes #108)
144 - automatic stacktrace mechanism is now turned off by default and can
145 be switched on by command line option "--stacktrace" (the automatic
146 stacktrace mechanism seems to be broken on most systems at the moment)
147 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
148 a pointer to the launched InstrumentEditor object
149 - added optional 3rd party user data parameter for following
150 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
151 InstrumentEditor::Launch(),
152 InstrumentManager::LaunchInstrumentEditor()
153 - theoretical fix: made SynchronizedConfig follow C++0x memory
154 model more strictly
155 - fixes for using large audio device buffers
156 - Windows: add the installation directory to the DLL search path
157 when loading an editor plugin (solves problems with VST and
158 gigedit on systems with other GTK versions installed)
159
160 * audio driver:
161 - removed the nonsense audio channel constraint (which was hard coded to
162 max. 100 audio channels) for most audio drivers
163 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
164 opposed to the LSCP specs
165 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
166 reflected the wrong value
167 - fixed a memory management bug in ASIO driver
168 - Makefile fix: JACK_CFLAGS wasn't used
169 - JACK: use jack_client_open instead of the deprecated
170 jack_client_new
171 - added (experimental) CoreAudio driver
172 - applied old fixes to the ASIO driver that were included in the
173 previous binary release but accidentally never committed to CVS
174 (fixes #117)
175 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
176 win64)
177 - VST: added support for sample rate and buffer size changes
178 - VST: close editor (Fantasia) when the VST is removed
179 - VST: avoid opening Fantasia more than once for each VST instance
180 - VST: export main function as "main" on Linux too (fix for
181 energyXT)
182 - VST: changed number of output channels from one stereo to 16
183 stereo
184 - added channel routing, fxsends and midi maps to the settings
185 stored in the plugin state
186 - performance optimization of AudioChannel::MixTo() and
187 AudioChannel::CopyTo() methods using GCC vector exensions
188 (if available)
189 - ASIO fixes: avoid initializing the device twice, avoid throwing
190 exception when getting parameters from a disconnected device
191
192 * MIDI driver:
193 - added JACK MIDI driver
194 - dispatch bank select as ordinary CC as well, the user might seriously
195 want to (mis)use it for some purpose ("fixed" in all current MIDI
196 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
197 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
198 CoreMidi or AU
199 - fixed mingw-w64 compilation error in MME driver
200 - made program change handling in MIDI thread real-time safe by
201 moving the logic to a non-RT thread
202 - fixed minor memory leak in ALSA driver
203
204 * instruments database:
205 - avoid time consuming samples scanning when adding instruments
206 to the instruments database
207 - added support for handling lost files in the instruments database
208 - Implemented option for adding instruments in separate directories
209 in the instruments database
210 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
211 - work-around for missing fnmatch function on Windows to make
212 instrument database compilable
213 - added instrument database support on Windows
214 works with both standalone mode and VST plugin.
215 the instruments DB file is located in
216 %USERPROFILE%\.linuxsampler\instruments.db which allows different
217 databases for each windows user
218 if no DB is present it automatically creates the .linuxsampler subdir
219 and then creates an empty DB
220 - fixed recursive import, which was broken on Windows
221
222 * Gigasampler format engine:
223 - fixed a memory leak that could happen when a channel was deleted
224 while notes were playing
225 - made it possible to load an instrument even if the audio thread
226 isn't running
227 - added partial support for the "Controller Triggered" MIDI rule,
228 enough for piano gigs with pedal noise samples
229 - minor fix: only mark FX sends as being modified if really the
230 respective FX send MIDI controller was used
231 - added support for GM global device volume SysEx message
232 (can be selected at compile time to either apply globally to the
233 whole sampler [default] or only to the sampler channels that are
234 connected to the respective MIDI input port the SysEx message arrived
235 on)
236 - bugfix: notes triggered at position 0 in the audio buffer were
237 sometimes wrongly killed in the same buffer, causing no sound to
238 be played
239 - added support for chromatic / drumkit mode Roland GS Sysex message
240 which is usally used to switch a part between chromatic sounds and
241 drumkit sounds (as opposed to their common default setting of MIDI
242 part 10 being a drumkit part and all other ones chromatic parts), in
243 LS however one can switch between the first 16 MIDI instrument maps
244 defined for the sampler
245 - made it possible to create multiple sample channels even if the
246 audio thread isn't running
247 - fixed crash when removing channel with active voices (#116)
248 - bugfix: on sample reference changes (instrument editor), only
249 un-cache the respective sample if it's really not used by any
250 sampler engine anymore
251 - re-cache samples in case they were changed by an instrument editor,
252 e.g. when a sample was added while playing (#82)
253 - fixed hanging notes which occured when note-off event had the exact
254 same time stamp as the voice's note-on event and occured both in the
255 same audio fragment cycle (fixes bug #112)
256 - added support for the "fine tune" and "pitch bend range"
257 instrument-level gig parameters
258 - fixed minor artifacts in pitch bend handling
259 - added support for GS Reset SysEx message
260 - allow gig files to use unlimited downward pitch shifting
261 - added a limit check for upward pitch shifting
262 - bugfix: sometimes, when playing a note twice fast, the second
263 note was silent
264 - fixed crash happening when a pitch bend event arrived at the
265 same time a new instrument was loading
266
267 * LSCP server:
268 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
269 react on MIDI data arriving on certain sampler channels (so far only
270 Note-On and Note-Off events are sent via this LSCP event)
271 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
272 react on MIDI data arriving on certain MIDI input devices (so far only
273 Note-On and Note-Off events are sent via this LSCP event)
274 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
275 SET DB_INSTRUMENT FILE_PATH
276 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
277 frontends to send MIDI messages to specific sampler channel
278 - added two additional fields to GET FILE INSTRUMENT INFO command -
279 KEY_BINDINGS and KEYSWITCH_BINDINGS
280 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
281 was incorrect
282 - Optimized the retrieval of the MIDI instrument mappings
283 - added new LSCP command "SET VOICES" to globally alter the maximum
284 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
285 be triggered respectively
286 - added new LSCP command "SET STREAMS" to globally alter the maximum
287 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
288 which will be triggered respectively
289 - bugfix: retry if "select" returns EINTR (this fixes a crash when
290 a gigedit file dialog is opened)
291 - close all connections when LSCPServer is deleted
292 - hard close of all sockets on exit
293 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
294 driver
295
296 * Bug fixes:
297 - fixed a crash which occurs when removing a sampler channel waiting
298 to start instrument loading after another channel
299 - fixed a crash which occurs when removing a sampler channel with
300 instrument loading in progress (bug #113)
301 - fixed termination caused by uncaught exception when adding MIDI
302 instrument with PERSISTENT load mode
303 - fixed possible iterator invalidations when resetting the sampler
304 - fixed memory leaks when issuing the following LSCP commands:
305 GET AUDIO_OUTPUT_DRIVER INFO
306 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
307 GET MIDI_INPUT_DRIVER INFO
308 GET MIDI_INPUT_DRIVER_PARAMETER INFO
309 - fixed possible compilation error when sqlite is not present
310 - fixed orphaned pointers when setting maximum voices limit (bug #118)
311 - fixed crash when changing the audio output device of a sampler
312 channel with loaded instrument and start playing notes
313 - fixed endless loop in Engine::SuspendAll() (bug #120)
314 - fixed a low-level atomic load function that was broken on 64-bit
315 PowerPC, which probably could cause crashes on that platform
316 - fixed a memory management error which could cause a crash when a
317 plugin was unloaded
318 - bugfix: two private structs had the same name, which could cause
319 problems if the linker chose the wrong constructor
320 - fixed low-level ConditionServer usage bug that caused lockups on
321 Windows
322
323
324 Version 0.5.1 (6 December 2007)
325
326 * packaging changes:
327 - added autoconf checks for pthread library
328 - added autoconf check for pthread bug found on certain NPTL-enabled
329 glibc versions (see Gentoo bug report #194076)
330 - added autoconf checks for MS Windows
331
332 * general changes:
333 - bugfix: the thread used by an editor plugin didn't die when the
334 editor closed
335 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
336 out all the space. operator--() did not apply size_mask after
337 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
338 order to avoid problems with the _NonVolatileReader functions.
339 - bugfix: Stream.h: added a missing divide by BytesPerSample in
340 GetWriteSpace(). Since this function is currently only used in
341 the stream's qsort() compare function, it didn't trigger any
342 bugs.
343 - Resampler.h, Synthesizer.h: cubic interpolation now works in
344 24bit mode too. Faster method to read 24bit words on little
345 endian machines (x86): replaced 3 byte reads + shifts with a 1
346 unaligned 32bit read and shift
347 - experimental support for MS Windows (MIDI input via MME, AUDIO
348 output via ASIO)
349 - made handling of SIGINT signal (Ctrl-C) a bit more robust
350 - support for monitoring the total number of active disk streams
351 (new LSCP commands: GET TOTAL_STREAM_COUNT,
352 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
353
354 * AUDIO driver:
355 - added Windows ASIO low latency audio driver
356
357 * MIDI driver:
358 - added MME Windows MIDI driver
359
360 * LSCP server:
361 - added support for Windows style path / filenames, however with
362 forward slash path separators instead of backslash
363 (i.e. "C:/foo/bar.gig")
364 - allow naughty liblscp to send non-string device parameters within
365 apostrophes as well
366 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
367 "LIST FILE INSTRUMENTS <file>" and
368 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
369 about an arbitrary instrument file on the system where the sampler is
370 running on
371
372 Version 0.5.0 (15 October 2007)
373
374 * packaging changes:
375 - config.h is not going to be installed along with liblinuxsampler's
376 API header files anymore
377 - only the API relevant header (and source) files will be exported to
378 the Doxygen API documentation (explicitly listed in Doxyfile.in)
379 - added completely new XCode project files for Mac OSX which is now
380 capable to execute our autoconf environment, thus no need anymore
381 to maintain the compile time configuration file (osx/version.h) for
382 OSX manually (patch by Toshi Nagata)
383 - fixed buggy boolean --enable-foo / --disable-foo configure script
384 parameters
385 - global.h now only covers global definitions that are needed for the
386 C++ API header files, all implementation internal global definitions
387 are now in global_private.h
388 - atomic.h is not exposed to the C++ API anymore
389 - no need to include config.h anymore for using LS's API header files
390 - fixed warnings in API doc generation
391
392 * general changes:
393 - replaced the old, confusing MIDI program change mechanism by a
394 flexible MIDI instrument mapper which allows to map arbitrary
395 (MIDI bank, MIDI program) pairs with arbitrary
396 (engine type, instrument file, file index) triplets which will be
397 loaded on the respective channel when such MIDI program change
398 messages arrive, beside that, each entry allows to define a life-time
399 strategy for the instrument, so the user can define whether the
400 instrument should i.e. be permanently loaded (to be able to switch
401 quickly among sounds) or i.e. loaded just on demand when the
402 respective program change arrives (to safe RAM space), as well as a
403 global volume factor for each entry, so the user can adjust the volume
404 dynamic of his mapped instrument collection without having to modify
405 the instrument files, also one can manage arbitrary amount of such
406 MIDI instrument maps and assign each sampler channel individually
407 a certain map, so that i.e. separation of normal instruments and
408 drumkits is possible
409 - new notification events for tracking changes to audio/MIDI devices,
410 MIDI instrument maps, MIDI instruments, FX sends, global volume.
411 - sampler was limited to load max. 200 instruments in the background
412 due to a constant size RingBuffer FIFO which is now replaced by a
413 dynamic (unlimited) size std::list FIFO
414 - added FX sends, these allow to route audio signals to arbitrary audio
415 output channels for being processed by external effect processors
416 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
417 controllers
418 - global (sampler wide) volume can now be controlled at runtime
419 - Implemented new, improved notification system
420 - fixed compilation errors regarding OSX
421 (patch by Toshi Nagata)
422 - implemented instruments database
423 - added support for escape sequences to the instruments database
424 - added highly experimental support for on-the-fly instrument editing
425 within the sampler's process (by using instrument editor plugins),
426 you'll notice the new "Registered instrument editors:" message on
427 startup, added a new LSCP command:
428 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
429 to spawn a matching instrument editor for the instrument on the
430 given sampler channel, the plugin path can be overridden at compile
431 time with ./configure --enable-plugin-dir=/some/dir
432 - added experimental code for synchronizing instrument editors hosted
433 in the sampler's process to safely edit instruments while playing
434 without a crash (hopefully) by either suspending single regions
435 wherever possible or if unavoidable whole engine(s)
436 - fixed several issues in fundamental "Thread" class: set scheduling
437 policy and priority on thread level, set a minimum stack size for
438 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
439 threads simply inherited properties of starting thread instead of
440 setting their own policy and priority
441 - minor fix in our automatic stack trace mechanism on crashes, the
442 main process did not wait for the stack trace process to finish
443 its output
444 - fixed some minor memory leaks
445 - reenabled assembly features support, at the moment only for
446 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
447 - minor assembly fix in x86 features detection (don't use the PIC
448 register, to avoid relocations in the text segment at runtime)
449 - POSIX callback functions of Thread.h are hidden
450
451 * MIDI driver:
452 - dispatch bank select (MSB and LSB) messages
453
454 * audio driver:
455 - the ALSA audio output driver parameters now reflect the correct
456 parameter value ranges for the respective selected sound card
457 (patch by Till Wimmer, a bit fixed and extended)
458
459 * Gigasampler format engine:
460 - if a filter is used and EG2 finishes before EG1, let the voice
461 die when EG2 has finished (this fixes a problem with clicks and
462 voice starvation for some gigs)
463 - playback is no longer disabled during instrument loading
464 - all notes playing on a channel that changes its instrument keep
465 playing with the old instrument until they get a note off
466 command
467 - EG fix: a release value of zero could cause noises or crash
468 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
469 - EG fine tuning: when attack is zero the EG starts at a level
470 above max sustain level, which means that there is a decay phase
471 even if sustain is 100%
472 - more EG fixes: the level could sometimes go below zero and cause
473 noises or crashes
474 - minor fix of EGDecay (patch by Toshi Nagata)
475 - fixed compiler error when --enable-override-filter-type was
476 supplied to the configure script (fixes #46)
477 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
478 instead of a fix value
479 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
480 127 (solo mode) only kill voices if the respective mode really
481 changed
482
483 * LSCP server:
484 - fixed compile time error for old Bison versions
485 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
486 - parser now supports extended ASCII character set
487 (up to ASCII code 255, i.e. includes now umlauts and accents)
488 - filename arguments in LSCP commands now allow to use escape
489 sequences, that is directly literal as one of: \', \", \\, \n, \r,
490 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
491 code value like \xf2) (fixes bug #24)
492 - the following LSCP commands now also support escape sequences for at
493 least one of their text-based parameters (i.e. name, description):
494 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
495 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
496 "SET DB_INSTRUMENT_DIRECTORY NAME",
497 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
498 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
499 "FIND DB_INSTRUMENT_DIRECTORIES"
500 - returns verbose syntax errors (line and column where syntax error
501 occured, the unexpected character and the actually expected, possible
502 character(s), the latter only if less than 5 possibilities)
503 - made sure that LSCP syntax is not affected by gigedit locale
504 settings
505 - bugfix regarding strings parameter lists: all comma separated lists
506 of strings were treated as being one string containing commas
507 (fixes #57)
508
509 * Bug fixes:
510 - fixed crash occurring on certain LSCP scripts (Bug 39)
511 - another thread safety fix for lscp "load engine" and "set
512 channel audio output device"
513 - fixed a crash which occurs when reassigning the same engine
514 on a sampler channel with connected MIDI device
515 - fixed a crash which occurs when changing the number of ports of a MIDI
516 device connected to a sampler channel to number less then or equal
517 to the index of the port to which the sampler channel is connected.
518 - The previous bindings were not been disconnected when altering
519 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
520 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
521 - The active stream/voice count statistic was incorrect.
522 - notification events were not been sent for some sampler
523 channel changes
524 - added default min and max values to restrict the number of allowed
525 audio output channels and MIDI input ports
526 - the connection to the PCM interface is now closed when destroying
527 an audio output device
528 - files with slash in their path or filename could not be loaded
529
530 * test cases:
531 - updated and fixed (haven't been touched in a while)
532
533 Version 0.4.0 (24 November 2006)
534
535 * packaging changes:
536 - changed deprecated copyright attribute to license; added ldconfig
537 to post-(un)install steps; added devel package for liblinuxsampler;
538 to linuxsampler.spec (RPM)
539 - install necessary development header files for allowing 3rd party
540 applications to link against liblinuxsampler
541 - liblinuxsampler's API documentation can be generated with 'make docs'
542 (Doxygen required)
543 - added benchmark to automatically detect the best triangle LFO
544 implementation (currently either an integer math solution or a
545 di-harmonic approximation), automatic detection can be overriden
546 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
547 configure script argument though (mandatory for cross-compilation)
548 - do not automatically pick optimized gcc flags if the user already
549 provided some on his own (as CXXFLAGS)
550 - added compile time option to disable processing of All-Notes-Off MIDI
551 messages
552 - added compile time options to allow disabling the various audio and
553 MIDI drivers
554 - fixed automatic GCC CPU switch detection on PPC
555 (patch by Ebrahim Mayat)
556
557 * Gigasampler format engine:
558 - extensive synthesis optimization
559 (reimplementation of EGs and LFO(s), removed synthesis parameter
560 prerendering and the synthesis parameter matrix in general, splitting
561 each audio fragment into subfragments now where each subfragment uses
562 constant pitch and filter coefficients. The volume coefficient is
563 linearly interpolated inside a subfragment, unless
564 --disable-interpolate-volume is set.)
565 - fine tuning of the EG modulation parameters
566 - improved filter cutoff calculation by adding support for the
567 following gig parameters: Cutoff freq (used when no cutoff
568 controller is defined), Control invert, Minimum cutoff, Velocity
569 curve and Velocity range. The keyboard tracking now scales
570 cutoff frequency instead of resonance.
571 - added support for gig parameter Resonance.
572 - fixed bug in sysex handling (patch by Juan Linietsky)
573 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
574 which can be overridden with --enable-global-attenuation
575 - EG fixes: made the length of "attack hold" stage more
576 accurate. Release stage can now start before attack stage
577 ends. Cancel release didn't work when sustain was zero. Attack
578 time now has a minimal value to prevent clicks.
579 - fixed pitch changes larger than one octave
580 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
581 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
582 all modes can be altered via standard GM messages, that is CC5 for
583 altering portamento time, CC65 for enabling / disabling portamento
584 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
585 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
586 parameter) and crossfade
587 - added support for the "attenuation controller threshold" gig
588 parameter
589 - added smoothing of volume changes caused by control change
590 messages
591 - sample loop parameters are now taken from the DimensionRegion
592 instead of the wave chunk
593 - fixed keyswitching for v3 gigs with a number of keyswitch splits
594 not equal to a power of two
595 - reimplementation of the filter algorithm. The new filter is more
596 accurate and supports all gig filter types, including bandreject
597 and lowpass turbo.
598 - real support for 24 bit samples - samples are not truncated to
599 16 bits anymore
600 - support for aftertouch (channel pressure, not polyphonic
601 aftertouch)
602 - LFO1 behaviour fixed (dampening from max volume instead of
603 amplifying from 0)
604
605 * LSCP server:
606 - fixed application exit on broken pipe error (fixes bug #20)
607 - fixed the notification messages delay due to lack of
608 network activity (fixes bug #26)
609 - fixed parser bug which occured on space(s) within device parameters
610 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
611
612 * audio driver:
613 - added aRts audio output driver (by no means RT safe)
614
615 * MIDI driver:
616 - fixed legacy sysex code which caused dispatching of MIDI SysEx
617 messages several times instead of once
618 - API extension for MIDI drivers which already supply exact time stamps
619 for events (i.e. for offline rendering based MIDI drivers)
620 - added checks for bad MIDI data
621
622 * linuxsampler application:
623 - show available sampler engine types on startup
624
625 * general changes:
626 - support for muting sampler channels and solo mode of the same, two new
627 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
628 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
629 introduced for this, the behavior is the same like on a mixer console
630 (patch by Grigor Iliev, a bit adjusted). Also added configure option
631 --enable-process-muted-channels which can be used to enable the
632 processing of muted channels.
633 - support for sostenuto pedal
634 - support for monitoring the total number of active voices
635 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
636 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
637 - fixed some memory management errors
638 - fixed some concurrency problems that could lead to crashes when
639 LSCP commands were executed
640 - fixed crash when instrument loading failed previously on the same
641 sampler channel (fixes bug #36)
642
643 Version 0.3.3 (15 July 2005)
644
645 * packaging changes:
646 - fixed compilation with gcc 4.0
647
648 * Gigasampler format engine:
649 - LFO preprocessing was performed even though the respective LFO was
650 disabled by the instrument patch (minor efficiency fix)
651 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
652 for volume ramp downs in the same fragment (needed for current voice
653 stealing implementation) then simply inform the user with a warning
654 about possible click sounds and reduce the volume ramp down
655 appropriately instead of cancelling the audio device connection
656
657 Version 0.3.2 (24 June 2005)
658
659 * packaging changes:
660 - updated autotools build files to compile on OS X
661 (conditional compilation of CoreMIDI and MidiShare drivers)
662 - hand-crafted assembly optimization code can be disabled with
663 './configure --disable-asm' (definitely not recommended)
664 - fixed 'make dist' rule to include all necessary files
665 - require automake (>= 1.5) for 'make -f Makefile.cvs'
666 (due to 'dist-bzip2' automake option)
667
668 * Gigasampler format engine:
669 - support for the gig parameters for "release velocity response" curves
670 - fine tuning of the EGADSR envelope
671 - volume of release triggered samples now depends on note-on velocity,
672 note length and gig parameter "release trigger decay" instead of
673 note-off velocity.
674 - revised voice stealing
675 (fixes crash and endless loop caused by voice stealing)
676 - don't reset scale tuning on instrument or audio output device change
677 - handle key group conflicts right at the beginning of each fragment
678 instead of when the respective voice is actually launched
679 (fixes undefined behavior if stolen voices belonged to a key group -
680 this case was followed by a "killed voice survived" error message)
681 - fixed minor issue with null/silence samples
682 (those stole voices even though they don't need a voice at all which
683 resulted in "voice stealing didn't work out" messages)
684 - don't reset volume, pan, pitch and MIDI controller values on
685 instrument or audio output device change
686
687 * LSCP server:
688 - fixed some crashes (patch by Grigor Iliev, fixes #19)
689 - fixed LSCP event "CHANNEL_INFO" notification
690 (e.g. did not notify on volume changes or MIDI program change events)
691
692 * linuxsampler application:
693 - added command line parameters --lscp-addr and --lscp-port to override
694 default IP address and port of LSCP server
695
696 Version 0.3.1 (24 May 2005)
697
698 * initial release
