File size: 34349 byte(s)
* sfz engine: improved support for exclusive groups (group, off_by and
  off_mode)
* minor valgrind fixes

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
16 * Gigasampler format engine:
17 - implemented the "round robin keyboard" dimension
18 - fixed round robin and random dimensions for cases when number of
19 dimension zones is not a power of two
20 - made round robin use a counter for each region instead of each
21 key
22
23 * SFZ format engine:
24 - Initial implementation (not usable yet)
25 - added support for v2 multiple stage envelope generators
26 - added a fine-tuned v1 envelope generator instead of using the
27 one from the gig engine
28 - fixed memory leak and memory handling errors
29 - added support for trigger=first, trigger=legato and sw_previous
30 - allow non-numerical key values ("C#4" for example)
31 - "key" opcode now sets pitch_keycenter too
32 - fixed error when unloading instrument with same sample used by
33 multiple regions
34 - added some opcode aliases, like loopmode for loop_mode, to be
35 more compatible
36 - added support for trigger=release and rt_decay
37 - added support for off_mode=normal
38 - added support for random, seq_position, seq_length and volume
39 - added v1 LFO opcodes to parser (no support in engine yet)

47 - RT-safeness: avoid malloc in audio thread
48 - fixed a bug that could cause voice stealing to fail
49 - optimized sample lookup
50 - improved support for exclusive groups (group, off_by and
51 off_mode)
52
53 * SoundFont format engine:
54 - Initial implementation (not usable yet)
55 - RT-safeness: avoid malloc in audio thread
56 - fixed a bug that could cause voice stealing to fail
57
58 * Host plugins:
59 - AU bugfix: failed to destroy its audio/MIDI devices
60 - Listen to all interfaces on Mac OS X (INADDR_ANY)
61 - VST bugfix: If the host called resume() before and after
62 changing sample rate or block size, the number of channels was
63 incorrectly set to two. This caused silence in Cubase 5.
64
65 * MIDI driver:
66 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
67 the ALSA sequencer client name
68

76
77 Version 1.0.0 (31 July 2009)
78
79 * packaging changes:
80 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
81 causing e.g. the libgig test to fail when
82 "./configure --disable-jack-driver" was used
83 (patch by Alexis Ballier)
84 - fixed compilation with gcc 4.3
85 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)

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