File size: 32592 byte(s)
* command line option '--profile' is currently disabled, since the
  respective profiling code is currently broken

1 Version CVS HEAD (?)
2
3 * General changes:
4 - Refactoring: moved the independent code from
5 the Gigasampler format engine to base classes
6 - command line option '--profile' is currently disabled, since the
7 respective profiling code is currently broken
8
9 * Gigasampler format engine:
10 - implemented the "round robin keyboard" dimension
11 - fixed round robin and random dimensions for cases when number of
12 dimension zones is not a power of two
13 - made round robin use a counter for each region instead of each
14 key
15
16 * SFZ format engine:
17 - Initial implementation (not usable yet)
18
19 * SoundFont format engine:
20 - Initial implementation (not usable yet)
21
22 * Host plugins:
23 - AU bugfix: failed to destroy its audio/MIDI devices
24 - Listen to all interfaces on Mac OS X (INADDR_ANY)
25 - VST bugfix: If the host called resume() before and after
26 changing sample rate or block size, the number of channels was
27 incorrectly set to two. This caused silence in Cubase 5.
28
29 * MIDI driver:
30 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
31 the ALSA sequencer client name
32
33 * LSCP server:
34 - added support for sending MIDI CC messages via LSCP command
35 "SEND CHANNEL MIDI_DATA CC <sampler-chan> <ctrl> <val>"
36
37 * Bug fixes:
38 - Fixed crash which may occur when MIDI key + transpose is out of range
39
40 Version 1.0.0 (31 July 2009)
41
42 * packaging changes:
43 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
44 causing e.g. the libgig test to fail when
45 "./configure --disable-jack-driver" was used
46 (patch by Alexis Ballier)
47 - fixed compilation with gcc 4.3
48 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
49 - fixed configure so it detects x86_64 (#107)
50 - fixes for building with newer MinGW versions
51 - fix for building with bison 2.4 (#111)
52 - fixed building with libgig installed in a non-standard directory
53 - minor fix in configure for mmsystem.h detection on MinGW
54 - Windows: look for editor plugins and Fantasia using base
55 directory of liblinuxsampler dll (look in the same directory and one
56 directory above)
57 - configure script fix: removed unconditional use of SSE
58 - fixed building with sqlite installed in a non-standard directory
59 - when cross-compiling, don't try to create instruments.db
60 - fix for new mingw-w64 version, which has usleep
61
62 * general changes:
63 - bugfix: on some POSIX systems instrument editor plugins refused to
64 load as we used a non-portable Linux specific struct field
65 (fixes bug #70, patch by Ronald Baljeu)
66 - fixed endless loop which occured when loading an instrument editor
67 plugin DLL on Windows systems failed
68 - fixed memory leaks that occurred when liblinuxsampler was unloaded
69 - optimized the SynchronizedConfig class so it doesn't wait
70 unnecessarily long after an update
71 - added support for notifying instrument editors on note-on / note-off
72 events (e.g. to highlight the pressed keys on the virtual keyboard
73 of gigedit)
74 - added support for triggering notes by instrument editors (see above)
75 - be verbose on DLL load errors (on Linux)
76 - fixed di-harmonic triangle LFO implementation (this LFO implementation
77 is only used by very few systems, most pick the int math
78 implementation, which is usually faster)
79 - fixes for audio drivers with varying buffer sizes
80 - experimental support for running LinuxSampler as a DSSI, LV2 and
81 VST plugin
82 - notification events for stream/voice count statistics are now sent
83 only when there are actual changes
84 - added memory ordering constraints to improve stability on
85 multi-core and multi-cpu systems
86 - maximum voices and disk streams can now be altered at runtime
87 - fixed CPU feature detection on x86_64 (maybe fixes #108)
88 - automatic stacktrace mechanism is now turned off by default and can
89 be switched on by command line option "--stacktrace" (the automatic
90 stacktrace mechanism seems to be broken on most systems at the moment)
91 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
92 a pointer to the launched InstrumentEditor object
93 - added optional 3rd party user data parameter for following
94 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
95 InstrumentEditor::Launch(),
96 InstrumentManager::LaunchInstrumentEditor()
97 - theoretical fix: made SynchronizedConfig follow C++0x memory
98 model more strictly
99 - fixes for using large audio device buffers
100 - Windows: add the installation directory to the DLL search path
101 when loading an editor plugin (solves problems with VST and
102 gigedit on systems with other GTK versions installed)
103
104 * audio driver:
105 - removed the nonsense audio channel constraint (which was hard coded to
106 max. 100 audio channels) for most audio drivers
107 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
108 opposed to the LSCP specs
109 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
110 reflected the wrong value
111 - fixed a memory management bug in ASIO driver
112 - Makefile fix: JACK_CFLAGS wasn't used
113 - JACK: use jack_client_open instead of the deprecated
114 jack_client_new
115 - added (experimental) CoreAudio driver
116 - applied old fixes to the ASIO driver that were included in the
117 previous binary release but accidentally never committed to CVS
118 (fixes #117)
119 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
120 win64)
121 - VST: added support for sample rate and buffer size changes
122 - VST: close editor (Fantasia) when the VST is removed
123 - VST: avoid opening Fantasia more than once for each VST instance
124 - VST: export main function as "main" on Linux too (fix for
125 energyXT)
126 - VST: changed number of output channels from one stereo to 16
127 stereo
128 - added channel routing, fxsends and midi maps to the settings
129 stored in the plugin state
130 - performance optimization of AudioChannel::MixTo() and
131 AudioChannel::CopyTo() methods using GCC vector exensions
132 (if available)
133 - ASIO fixes: avoid initializing the device twice, avoid throwing
134 exception when getting parameters from a disconnected device
135
136 * MIDI driver:
137 - added JACK MIDI driver
138 - dispatch bank select as ordinary CC as well, the user might seriously
139 want to (mis)use it for some purpose ("fixed" in all current MIDI
140 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
141 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
142 CoreMidi or AU
143 - fixed mingw-w64 compilation error in MME driver
144 - made program change handling in MIDI thread real-time safe by
145 moving the logic to a non-RT thread
146 - fixed minor memory leak in ALSA driver
147
148 * instruments database:
149 - avoid time consuming samples scanning when adding instruments
150 to the instruments database
151 - added support for handling lost files in the instruments database
152 - Implemented option for adding instruments in separate directories
153 in the instruments database
154 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
155 - work-around for missing fnmatch function on Windows to make
156 instrument database compilable
157 - added instrument database support on Windows
158 works with both standalone mode and VST plugin.
159 the instruments DB file is located in
160 %USERPROFILE%\.linuxsampler\instruments.db which allows different
161 databases for each windows user
162 if no DB is present it automatically creates the .linuxsampler subdir
163 and then creates an empty DB
164 - fixed recursive import, which was broken on Windows
165
166 * Gigasampler format engine:
167 - fixed a memory leak that could happen when a channel was deleted
168 while notes were playing
169 - made it possible to load an instrument even if the audio thread
170 isn't running
171 - added partial support for the "Controller Triggered" MIDI rule,
172 enough for piano gigs with pedal noise samples
173 - minor fix: only mark FX sends as being modified if really the
174 respective FX send MIDI controller was used
175 - added support for GM global device volume SysEx message
176 (can be selected at compile time to either apply globally to the
177 whole sampler [default] or only to the sampler channels that are
178 connected to the respective MIDI input port the SysEx message arrived
179 on)
180 - bugfix: notes triggered at position 0 in the audio buffer were
181 sometimes wrongly killed in the same buffer, causing no sound to
182 be played
183 - added support for chromatic / drumkit mode Roland GS Sysex message
184 which is usally used to switch a part between chromatic sounds and
185 drumkit sounds (as opposed to their common default setting of MIDI
186 part 10 being a drumkit part and all other ones chromatic parts), in
187 LS however one can switch between the first 16 MIDI instrument maps
188 defined for the sampler
189 - made it possible to create multiple sample channels even if the
190 audio thread isn't running
191 - fixed crash when removing channel with active voices (#116)
192 - bugfix: on sample reference changes (instrument editor), only
193 un-cache the respective sample if it's really not used by any
194 sampler engine anymore
195 - re-cache samples in case they were changed by an instrument editor,
196 e.g. when a sample was added while playing (#82)
197 - fixed hanging notes which occured when note-off event had the exact
198 same time stamp as the voice's note-on event and occured both in the
199 same audio fragment cycle (fixes bug #112)
200 - added support for the "fine tune" and "pitch bend range"
201 instrument-level gig parameters
202 - fixed minor artifacts in pitch bend handling
203 - added support for GS Reset SysEx message
204 - allow gig files to use unlimited downward pitch shifting
205 - added a limit check for upward pitch shifting
206 - bugfix: sometimes, when playing a note twice fast, the second
207 note was silent
208 - fixed crash happening when a pitch bend event arrived at the
209 same time a new instrument was loading
210
211 * LSCP server:
212 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
213 react on MIDI data arriving on certain sampler channels (so far only
214 Note-On and Note-Off events are sent via this LSCP event)
215 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
216 react on MIDI data arriving on certain MIDI input devices (so far only
217 Note-On and Note-Off events are sent via this LSCP event)
218 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
219 SET DB_INSTRUMENT FILE_PATH
220 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
221 frontends to send MIDI messages to specific sampler channel
222 - added two additional fields to GET FILE INSTRUMENT INFO command -
223 KEY_BINDINGS and KEYSWITCH_BINDINGS
224 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
225 was incorrect
226 - Optimized the retrieval of the MIDI instrument mappings
227 - added new LSCP command "SET VOICES" to globally alter the maximum
228 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
229 be triggered respectively
230 - added new LSCP command "SET STREAMS" to globally alter the maximum
231 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
232 which will be triggered respectively
233 - bugfix: retry if "select" returns EINTR (this fixes a crash when
234 a gigedit file dialog is opened)
235 - close all connections when LSCPServer is deleted
236 - hard close of all sockets on exit
237 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
238 driver
239
240 * Bug fixes:
241 - fixed a crash which occurs when removing a sampler channel waiting
242 to start instrument loading after another channel
243 - fixed a crash which occurs when removing a sampler channel with
244 instrument loading in progress (bug #113)
245 - fixed termination caused by uncaught exception when adding MIDI
246 instrument with PERSISTENT load mode
247 - fixed possible iterator invalidations when resetting the sampler
248 - fixed memory leaks when issuing the following LSCP commands:
249 GET AUDIO_OUTPUT_DRIVER INFO
250 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
251 GET MIDI_INPUT_DRIVER INFO
252 GET MIDI_INPUT_DRIVER_PARAMETER INFO
253 - fixed possible compilation error when sqlite is not present
254 - fixed orphaned pointers when setting maximum voices limit (bug #118)
255 - fixed crash when changing the audio output device of a sampler
256 channel with loaded instrument and start playing notes
257 - fixed endless loop in Engine::SuspendAll() (bug #120)
258 - fixed a low-level atomic load function that was broken on 64-bit
259 PowerPC, which probably could cause crashes on that platform
260 - fixed a memory management error which could cause a crash when a
261 plugin was unloaded
262 - bugfix: two private structs had the same name, which could cause
263 problems if the linker chose the wrong constructor
264 - fixed low-level ConditionServer usage bug that caused lockups on
265 Windows
266
267
268 Version 0.5.1 (6 December 2007)
269
270 * packaging changes:
271 - added autoconf checks for pthread library
272 - added autoconf check for pthread bug found on certain NPTL-enabled
273 glibc versions (see Gentoo bug report #194076)
274 - added autoconf checks for MS Windows
275
276 * general changes:
277 - bugfix: the thread used by an editor plugin didn't die when the
278 editor closed
279 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
280 out all the space. operator--() did not apply size_mask after
281 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
282 order to avoid problems with the _NonVolatileReader functions.
283 - bugfix: Stream.h: added a missing divide by BytesPerSample in
284 GetWriteSpace(). Since this function is currently only used in
285 the stream's qsort() compare function, it didn't trigger any
286 bugs.
287 - Resampler.h, Synthesizer.h: cubic interpolation now works in
288 24bit mode too. Faster method to read 24bit words on little
289 endian machines (x86): replaced 3 byte reads + shifts with a 1
290 unaligned 32bit read and shift
291 - experimental support for MS Windows (MIDI input via MME, AUDIO
292 output via ASIO)
293 - made handling of SIGINT signal (Ctrl-C) a bit more robust
294 - support for monitoring the total number of active disk streams
295 (new LSCP commands: GET TOTAL_STREAM_COUNT,
296 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
297
298 * AUDIO driver:
299 - added Windows ASIO low latency audio driver
300
301 * MIDI driver:
302 - added MME Windows MIDI driver
303
304 * LSCP server:
305 - added support for Windows style path / filenames, however with
306 forward slash path separators instead of backslash
307 (i.e. "C:/foo/bar.gig")
308 - allow naughty liblscp to send non-string device parameters within
309 apostrophes as well
310 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
311 "LIST FILE INSTRUMENTS <file>" and
312 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
313 about an arbitrary instrument file on the system where the sampler is
314 running on
315
316 Version 0.5.0 (15 October 2007)
317
318 * packaging changes:
319 - config.h is not going to be installed along with liblinuxsampler's
320 API header files anymore
321 - only the API relevant header (and source) files will be exported to
322 the Doxygen API documentation (explicitly listed in Doxyfile.in)
323 - added completely new XCode project files for Mac OSX which is now
324 capable to execute our autoconf environment, thus no need anymore
325 to maintain the compile time configuration file (osx/version.h) for
326 OSX manually (patch by Toshi Nagata)
327 - fixed buggy boolean --enable-foo / --disable-foo configure script
328 parameters
329 - global.h now only covers global definitions that are needed for the
330 C++ API header files, all implementation internal global definitions
331 are now in global_private.h
332 - atomic.h is not exposed to the C++ API anymore
333 - no need to include config.h anymore for using LS's API header files
334 - fixed warnings in API doc generation
335
336 * general changes:
337 - replaced the old, confusing MIDI program change mechanism by a
338 flexible MIDI instrument mapper which allows to map arbitrary
339 (MIDI bank, MIDI program) pairs with arbitrary
340 (engine type, instrument file, file index) triplets which will be
341 loaded on the respective channel when such MIDI program change
342 messages arrive, beside that, each entry allows to define a life-time
343 strategy for the instrument, so the user can define whether the
344 instrument should i.e. be permanently loaded (to be able to switch
345 quickly among sounds) or i.e. loaded just on demand when the
346 respective program change arrives (to safe RAM space), as well as a
347 global volume factor for each entry, so the user can adjust the volume
348 dynamic of his mapped instrument collection without having to modify
349 the instrument files, also one can manage arbitrary amount of such
350 MIDI instrument maps and assign each sampler channel individually
351 a certain map, so that i.e. separation of normal instruments and
352 drumkits is possible
353 - new notification events for tracking changes to audio/MIDI devices,
354 MIDI instrument maps, MIDI instruments, FX sends, global volume.
355 - sampler was limited to load max. 200 instruments in the background
356 due to a constant size RingBuffer FIFO which is now replaced by a
357 dynamic (unlimited) size std::list FIFO
358 - added FX sends, these allow to route audio signals to arbitrary audio
359 output channels for being processed by external effect processors
360 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
361 controllers
362 - global (sampler wide) volume can now be controlled at runtime
363 - Implemented new, improved notification system
364 - fixed compilation errors regarding OSX
365 (patch by Toshi Nagata)
366 - implemented instruments database
367 - added support for escape sequences to the instruments database
368 - added highly experimental support for on-the-fly instrument editing
369 within the sampler's process (by using instrument editor plugins),
370 you'll notice the new "Registered instrument editors:" message on
371 startup, added a new LSCP command:
372 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
373 to spawn a matching instrument editor for the instrument on the
374 given sampler channel, the plugin path can be overridden at compile
375 time with ./configure --enable-plugin-dir=/some/dir
376 - added experimental code for synchronizing instrument editors hosted
377 in the sampler's process to safely edit instruments while playing
378 without a crash (hopefully) by either suspending single regions
379 wherever possible or if unavoidable whole engine(s)
380 - fixed several issues in fundamental "Thread" class: set scheduling
381 policy and priority on thread level, set a minimum stack size for
382 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
383 threads simply inherited properties of starting thread instead of
384 setting their own policy and priority
385 - minor fix in our automatic stack trace mechanism on crashes, the
386 main process did not wait for the stack trace process to finish
387 its output
388 - fixed some minor memory leaks
389 - reenabled assembly features support, at the moment only for
390 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
391 - minor assembly fix in x86 features detection (don't use the PIC
392 register, to avoid relocations in the text segment at runtime)
393 - POSIX callback functions of Thread.h are hidden
394
395 * MIDI driver:
396 - dispatch bank select (MSB and LSB) messages
397
398 * audio driver:
399 - the ALSA audio output driver parameters now reflect the correct
400 parameter value ranges for the respective selected sound card
401 (patch by Till Wimmer, a bit fixed and extended)
402
403 * Gigasampler format engine:
404 - if a filter is used and EG2 finishes before EG1, let the voice
405 die when EG2 has finished (this fixes a problem with clicks and
406 voice starvation for some gigs)
407 - playback is no longer disabled during instrument loading
408 - all notes playing on a channel that changes its instrument keep
409 playing with the old instrument until they get a note off
410 command
411 - EG fix: a release value of zero could cause noises or crash
412 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
413 - EG fine tuning: when attack is zero the EG starts at a level
414 above max sustain level, which means that there is a decay phase
415 even if sustain is 100%
416 - more EG fixes: the level could sometimes go below zero and cause
417 noises or crashes
418 - minor fix of EGDecay (patch by Toshi Nagata)
419 - fixed compiler error when --enable-override-filter-type was
420 supplied to the configure script (fixes #46)
421 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
422 instead of a fix value
423 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
424 127 (solo mode) only kill voices if the respective mode really
425 changed
426
427 * LSCP server:
428 - fixed compile time error for old Bison versions
429 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
430 - parser now supports extended ASCII character set
431 (up to ASCII code 255, i.e. includes now umlauts and accents)
432 - filename arguments in LSCP commands now allow to use escape
433 sequences, that is directly literal as one of: \', \", \\, \n, \r,
434 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
435 code value like \xf2) (fixes bug #24)
436 - the following LSCP commands now also support escape sequences for at
437 least one of their text-based parameters (i.e. name, description):
438 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
439 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
440 "SET DB_INSTRUMENT_DIRECTORY NAME",
441 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
442 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
443 "FIND DB_INSTRUMENT_DIRECTORIES"
444 - returns verbose syntax errors (line and column where syntax error
445 occured, the unexpected character and the actually expected, possible
446 character(s), the latter only if less than 5 possibilities)
447 - made sure that LSCP syntax is not affected by gigedit locale
448 settings
449 - bugfix regarding strings parameter lists: all comma separated lists
450 of strings were treated as being one string containing commas
451 (fixes #57)
452
453 * Bug fixes:
454 - fixed crash occurring on certain LSCP scripts (Bug 39)
455 - another thread safety fix for lscp "load engine" and "set
456 channel audio output device"
457 - fixed a crash which occurs when reassigning the same engine
458 on a sampler channel with connected MIDI device
459 - fixed a crash which occurs when changing the number of ports of a MIDI
460 device connected to a sampler channel to number less then or equal
461 to the index of the port to which the sampler channel is connected.
462 - The previous bindings were not been disconnected when altering
463 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
464 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
465 - The active stream/voice count statistic was incorrect.
466 - notification events were not been sent for some sampler
467 channel changes
468 - added default min and max values to restrict the number of allowed
469 audio output channels and MIDI input ports
470 - the connection to the PCM interface is now closed when destroying
471 an audio output device
472 - files with slash in their path or filename could not be loaded
473
474 * test cases:
475 - updated and fixed (haven't been touched in a while)
476
477 Version 0.4.0 (24 November 2006)
478
479 * packaging changes:
480 - changed deprecated copyright attribute to license; added ldconfig
481 to post-(un)install steps; added devel package for liblinuxsampler;
482 to linuxsampler.spec (RPM)
483 - install necessary development header files for allowing 3rd party
484 applications to link against liblinuxsampler
485 - liblinuxsampler's API documentation can be generated with 'make docs'
486 (Doxygen required)
487 - added benchmark to automatically detect the best triangle LFO
488 implementation (currently either an integer math solution or a
489 di-harmonic approximation), automatic detection can be overriden
490 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
491 configure script argument though (mandatory for cross-compilation)
492 - do not automatically pick optimized gcc flags if the user already
493 provided some on his own (as CXXFLAGS)
494 - added compile time option to disable processing of All-Notes-Off MIDI
495 messages
496 - added compile time options to allow disabling the various audio and
497 MIDI drivers
498 - fixed automatic GCC CPU switch detection on PPC
499 (patch by Ebrahim Mayat)
500
501 * Gigasampler format engine:
502 - extensive synthesis optimization
503 (reimplementation of EGs and LFO(s), removed synthesis parameter
504 prerendering and the synthesis parameter matrix in general, splitting
505 each audio fragment into subfragments now where each subfragment uses
506 constant pitch and filter coefficients. The volume coefficient is
507 linearly interpolated inside a subfragment, unless
508 --disable-interpolate-volume is set.)
509 - fine tuning of the EG modulation parameters
510 - improved filter cutoff calculation by adding support for the
511 following gig parameters: Cutoff freq (used when no cutoff
512 controller is defined), Control invert, Minimum cutoff, Velocity
513 curve and Velocity range. The keyboard tracking now scales
514 cutoff frequency instead of resonance.
515 - added support for gig parameter Resonance.
516 - fixed bug in sysex handling (patch by Juan Linietsky)
517 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
518 which can be overridden with --enable-global-attenuation
519 - EG fixes: made the length of "attack hold" stage more
520 accurate. Release stage can now start before attack stage
521 ends. Cancel release didn't work when sustain was zero. Attack
522 time now has a minimal value to prevent clicks.
523 - fixed pitch changes larger than one octave
524 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
525 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
526 all modes can be altered via standard GM messages, that is CC5 for
527 altering portamento time, CC65 for enabling / disabling portamento
528 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
529 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
530 parameter) and crossfade
531 - added support for the "attenuation controller threshold" gig
532 parameter
533 - added smoothing of volume changes caused by control change
534 messages
535 - sample loop parameters are now taken from the DimensionRegion
536 instead of the wave chunk
537 - fixed keyswitching for v3 gigs with a number of keyswitch splits
538 not equal to a power of two
539 - reimplementation of the filter algorithm. The new filter is more
540 accurate and supports all gig filter types, including bandreject
541 and lowpass turbo.
542 - real support for 24 bit samples - samples are not truncated to
543 16 bits anymore
544 - support for aftertouch (channel pressure, not polyphonic
545 aftertouch)
546 - LFO1 behaviour fixed (dampening from max volume instead of
547 amplifying from 0)
548
549 * LSCP server:
550 - fixed application exit on broken pipe error (fixes bug #20)
551 - fixed the notification messages delay due to lack of
552 network activity (fixes bug #26)
553 - fixed parser bug which occured on space(s) within device parameters
554 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
555
556 * audio driver:
557 - added aRts audio output driver (by no means RT safe)
558
559 * MIDI driver:
560 - fixed legacy sysex code which caused dispatching of MIDI SysEx
561 messages several times instead of once
562 - API extension for MIDI drivers which already supply exact time stamps
563 for events (i.e. for offline rendering based MIDI drivers)
564 - added checks for bad MIDI data
565
566 * linuxsampler application:
567 - show available sampler engine types on startup
568
569 * general changes:
570 - support for muting sampler channels and solo mode of the same, two new
571 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
572 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
573 introduced for this, the behavior is the same like on a mixer console
574 (patch by Grigor Iliev, a bit adjusted). Also added configure option
575 --enable-process-muted-channels which can be used to enable the
576 processing of muted channels.
577 - support for sostenuto pedal
578 - support for monitoring the total number of active voices
579 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
580 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
581 - fixed some memory management errors
582 - fixed some concurrency problems that could lead to crashes when
583 LSCP commands were executed
584 - fixed crash when instrument loading failed previously on the same
585 sampler channel (fixes bug #36)
586
587 Version 0.3.3 (15 July 2005)
588
589 * packaging changes:
590 - fixed compilation with gcc 4.0
591
592 * Gigasampler format engine:
593 - LFO preprocessing was performed even though the respective LFO was
594 disabled by the instrument patch (minor efficiency fix)
595 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
596 for volume ramp downs in the same fragment (needed for current voice
597 stealing implementation) then simply inform the user with a warning
598 about possible click sounds and reduce the volume ramp down
599 appropriately instead of cancelling the audio device connection
600
601 Version 0.3.2 (24 June 2005)
602
603 * packaging changes:
604 - updated autotools build files to compile on OS X
605 (conditional compilation of CoreMIDI and MidiShare drivers)
606 - hand-crafted assembly optimization code can be disabled with
607 './configure --disable-asm' (definitely not recommended)
608 - fixed 'make dist' rule to include all necessary files
609 - require automake (>= 1.5) for 'make -f Makefile.cvs'
610 (due to 'dist-bzip2' automake option)
611
612 * Gigasampler format engine:
613 - support for the gig parameters for "release velocity response" curves
614 - fine tuning of the EGADSR envelope
615 - volume of release triggered samples now depends on note-on velocity,
616 note length and gig parameter "release trigger decay" instead of
617 note-off velocity.
618 - revised voice stealing
619 (fixes crash and endless loop caused by voice stealing)
620 - don't reset scale tuning on instrument or audio output device change
621 - handle key group conflicts right at the beginning of each fragment
622 instead of when the respective voice is actually launched
623 (fixes undefined behavior if stolen voices belonged to a key group -
624 this case was followed by a "killed voice survived" error message)
625 - fixed minor issue with null/silence samples
626 (those stole voices even though they don't need a voice at all which
627 resulted in "voice stealing didn't work out" messages)
628 - don't reset volume, pan, pitch and MIDI controller values on
629 instrument or audio output device change
630
631 * LSCP server:
632 - fixed some crashes (patch by Grigor Iliev, fixes #19)
633 - fixed LSCP event "CHANNEL_INFO" notification
634 (e.g. did not notify on volume changes or MIDI program change events)
635
636 * linuxsampler application:
637 - added command line parameters --lscp-addr and --lscp-port to override
638 default IP address and port of LSCP server
639
640 Version 0.3.1 (24 May 2005)
641
642 * initial release
