* sfz engine: added support for controller triggered regions
  (on_locc/on_hicc)
* sfz engine: added support for loop_mode=one_shot

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)

49 - optimized sample lookup
50 - improved support for exclusive groups (group, off_by and
51 off_mode)
52 - added support for controller triggered regions (on_locc/on_hicc)

54
55 * SoundFont format engine:
56 - Initial implementation (not usable yet)
57 - RT-safeness: avoid malloc in audio thread

59
60 * Host plugins:
61 - AU bugfix: failed to destroy its audio/MIDI devices
62 - Listen to all interfaces on Mac OS X (INADDR_ANY)
63 - VST bugfix: If the host called resume() before and after
64 changing sample rate or block size, the number of channels was
65 incorrectly set to two. This caused silence in Cubase 5.
66
67 * MIDI driver:
68 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
69 the ALSA sequencer client name

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

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