File size: 33417 byte(s)
* sfz/sf2 engines: fixed memory leak and memory handling errors
* sfz engine: added support for sw_trigger=first, sw_trigger=legato
  and sw_previous
* sfz parser: allow non-numerical key values ("C#4" for example)
* sfz engine: "key" opcode now sets pitch_keycenter too
* sfz engine: fixed error when unloading instrument with same sample
  used by multiple regions
* sfz parser: added some opcode aliases, like loopmode for loop_mode,
  to be more compatible

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 - Introduced support for optional environment variable
9 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
10 where the sampler shall look for instrument editor plugins
11 (patch by Luis Garrido, slightly modified).
12
13 * Gigasampler format engine:
14 - implemented the "round robin keyboard" dimension
15 - fixed round robin and random dimensions for cases when number of
16 dimension zones is not a power of two
17 - made round robin use a counter for each region instead of each
18 key
19
20 * SFZ format engine:
21 - Initial implementation (not usable yet)
22 - added support for v2 multiple stage envelope generators
23 - added a fine-tuned v1 envelope generator instead of using the
24 one from the gig engine
25 - fixed memory leak and memory handling errors
26 - added support for sw_trigger=first, sw_trigger=legato and
27 sw_previous
28 - allow non-numerical key values ("C#4" for example)
29 - "key" opcode now sets pitch_keycenter too
30 - fixed error when unloading instrument with same sample used by
31 multiple regions
32 - added some opcode aliases, like loopmode for loop_mode, to be
33 more compatible
34
35 * SoundFont format engine:
36 - Initial implementation (not usable yet)
37
38 * Host plugins:
39 - AU bugfix: failed to destroy its audio/MIDI devices
40 - Listen to all interfaces on Mac OS X (INADDR_ANY)
41 - VST bugfix: If the host called resume() before and after
42 changing sample rate or block size, the number of channels was
43 incorrectly set to two. This caused silence in Cubase 5.
44
45 * MIDI driver:
46 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
47 the ALSA sequencer client name
48
49 * LSCP server:
50 - added support for sending MIDI CC messages via LSCP command
51 "SEND CHANNEL MIDI_DATA CC <sampler-chan> <ctrl> <val>"
52
53 * Bug fixes:
54 - Fixed crash which may occur when MIDI key + transpose is out of range
55
56 Version 1.0.0 (31 July 2009)
57
58 * packaging changes:
59 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
60 causing e.g. the libgig test to fail when
61 "./configure --disable-jack-driver" was used
62 (patch by Alexis Ballier)
63 - fixed compilation with gcc 4.3
64 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
65 - fixed configure so it detects x86_64 (#107)
66 - fixes for building with newer MinGW versions
67 - fix for building with bison 2.4 (#111)
68 - fixed building with libgig installed in a non-standard directory
69 - minor fix in configure for mmsystem.h detection on MinGW
70 - Windows: look for editor plugins and Fantasia using base
71 directory of liblinuxsampler dll (look in the same directory and one
72 directory above)
73 - configure script fix: removed unconditional use of SSE
74 - fixed building with sqlite installed in a non-standard directory
75 - when cross-compiling, don't try to create instruments.db
76 - fix for new mingw-w64 version, which has usleep
77
78 * general changes:
79 - bugfix: on some POSIX systems instrument editor plugins refused to
80 load as we used a non-portable Linux specific struct field
81 (fixes bug #70, patch by Ronald Baljeu)
82 - fixed endless loop which occured when loading an instrument editor
83 plugin DLL on Windows systems failed
84 - fixed memory leaks that occurred when liblinuxsampler was unloaded
85 - optimized the SynchronizedConfig class so it doesn't wait
86 unnecessarily long after an update
87 - added support for notifying instrument editors on note-on / note-off
88 events (e.g. to highlight the pressed keys on the virtual keyboard
89 of gigedit)
90 - added support for triggering notes by instrument editors (see above)
91 - be verbose on DLL load errors (on Linux)
92 - fixed di-harmonic triangle LFO implementation (this LFO implementation
93 is only used by very few systems, most pick the int math
94 implementation, which is usually faster)
95 - fixes for audio drivers with varying buffer sizes
96 - experimental support for running LinuxSampler as a DSSI, LV2 and
97 VST plugin
98 - notification events for stream/voice count statistics are now sent
99 only when there are actual changes
100 - added memory ordering constraints to improve stability on
101 multi-core and multi-cpu systems
102 - maximum voices and disk streams can now be altered at runtime
103 - fixed CPU feature detection on x86_64 (maybe fixes #108)
104 - automatic stacktrace mechanism is now turned off by default and can
105 be switched on by command line option "--stacktrace" (the automatic
106 stacktrace mechanism seems to be broken on most systems at the moment)
107 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
108 a pointer to the launched InstrumentEditor object
109 - added optional 3rd party user data parameter for following
110 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
111 InstrumentEditor::Launch(),
112 InstrumentManager::LaunchInstrumentEditor()
113 - theoretical fix: made SynchronizedConfig follow C++0x memory
114 model more strictly
115 - fixes for using large audio device buffers
116 - Windows: add the installation directory to the DLL search path
117 when loading an editor plugin (solves problems with VST and
118 gigedit on systems with other GTK versions installed)
119
120 * audio driver:
121 - removed the nonsense audio channel constraint (which was hard coded to
122 max. 100 audio channels) for most audio drivers
123 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
124 opposed to the LSCP specs
125 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
126 reflected the wrong value
127 - fixed a memory management bug in ASIO driver
128 - Makefile fix: JACK_CFLAGS wasn't used
129 - JACK: use jack_client_open instead of the deprecated
130 jack_client_new
131 - added (experimental) CoreAudio driver
132 - applied old fixes to the ASIO driver that were included in the
133 previous binary release but accidentally never committed to CVS
134 (fixes #117)
135 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
136 win64)
137 - VST: added support for sample rate and buffer size changes
138 - VST: close editor (Fantasia) when the VST is removed
139 - VST: avoid opening Fantasia more than once for each VST instance
140 - VST: export main function as "main" on Linux too (fix for
141 energyXT)
142 - VST: changed number of output channels from one stereo to 16
143 stereo
144 - added channel routing, fxsends and midi maps to the settings
145 stored in the plugin state
146 - performance optimization of AudioChannel::MixTo() and
147 AudioChannel::CopyTo() methods using GCC vector exensions
148 (if available)
149 - ASIO fixes: avoid initializing the device twice, avoid throwing
150 exception when getting parameters from a disconnected device
151
152 * MIDI driver:
153 - added JACK MIDI driver
154 - dispatch bank select as ordinary CC as well, the user might seriously
155 want to (mis)use it for some purpose ("fixed" in all current MIDI
156 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
157 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
158 CoreMidi or AU
159 - fixed mingw-w64 compilation error in MME driver
160 - made program change handling in MIDI thread real-time safe by
161 moving the logic to a non-RT thread
162 - fixed minor memory leak in ALSA driver
163
164 * instruments database:
165 - avoid time consuming samples scanning when adding instruments
166 to the instruments database
167 - added support for handling lost files in the instruments database
168 - Implemented option for adding instruments in separate directories
169 in the instruments database
170 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
171 - work-around for missing fnmatch function on Windows to make
172 instrument database compilable
173 - added instrument database support on Windows
174 works with both standalone mode and VST plugin.
175 the instruments DB file is located in
176 %USERPROFILE%\.linuxsampler\instruments.db which allows different
177 databases for each windows user
178 if no DB is present it automatically creates the .linuxsampler subdir
179 and then creates an empty DB
180 - fixed recursive import, which was broken on Windows
181
182 * Gigasampler format engine:
183 - fixed a memory leak that could happen when a channel was deleted
184 while notes were playing
185 - made it possible to load an instrument even if the audio thread
186 isn't running
187 - added partial support for the "Controller Triggered" MIDI rule,
188 enough for piano gigs with pedal noise samples
189 - minor fix: only mark FX sends as being modified if really the
190 respective FX send MIDI controller was used
191 - added support for GM global device volume SysEx message
192 (can be selected at compile time to either apply globally to the
193 whole sampler [default] or only to the sampler channels that are
194 connected to the respective MIDI input port the SysEx message arrived
195 on)
196 - bugfix: notes triggered at position 0 in the audio buffer were
197 sometimes wrongly killed in the same buffer, causing no sound to
198 be played
199 - added support for chromatic / drumkit mode Roland GS Sysex message
200 which is usally used to switch a part between chromatic sounds and
201 drumkit sounds (as opposed to their common default setting of MIDI
202 part 10 being a drumkit part and all other ones chromatic parts), in
203 LS however one can switch between the first 16 MIDI instrument maps
204 defined for the sampler
205 - made it possible to create multiple sample channels even if the
206 audio thread isn't running
207 - fixed crash when removing channel with active voices (#116)
208 - bugfix: on sample reference changes (instrument editor), only
209 un-cache the respective sample if it's really not used by any
210 sampler engine anymore
211 - re-cache samples in case they were changed by an instrument editor,
212 e.g. when a sample was added while playing (#82)
213 - fixed hanging notes which occured when note-off event had the exact
214 same time stamp as the voice's note-on event and occured both in the
215 same audio fragment cycle (fixes bug #112)
216 - added support for the "fine tune" and "pitch bend range"
217 instrument-level gig parameters
218 - fixed minor artifacts in pitch bend handling
219 - added support for GS Reset SysEx message
220 - allow gig files to use unlimited downward pitch shifting
221 - added a limit check for upward pitch shifting
222 - bugfix: sometimes, when playing a note twice fast, the second
223 note was silent
224 - fixed crash happening when a pitch bend event arrived at the
225 same time a new instrument was loading
226
227 * LSCP server:
228 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
229 react on MIDI data arriving on certain sampler channels (so far only
230 Note-On and Note-Off events are sent via this LSCP event)
231 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
232 react on MIDI data arriving on certain MIDI input devices (so far only
233 Note-On and Note-Off events are sent via this LSCP event)
234 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
235 SET DB_INSTRUMENT FILE_PATH
236 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
237 frontends to send MIDI messages to specific sampler channel
238 - added two additional fields to GET FILE INSTRUMENT INFO command -
239 KEY_BINDINGS and KEYSWITCH_BINDINGS
240 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
241 was incorrect
242 - Optimized the retrieval of the MIDI instrument mappings
243 - added new LSCP command "SET VOICES" to globally alter the maximum
244 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
245 be triggered respectively
246 - added new LSCP command "SET STREAMS" to globally alter the maximum
247 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
248 which will be triggered respectively
249 - bugfix: retry if "select" returns EINTR (this fixes a crash when
250 a gigedit file dialog is opened)
251 - close all connections when LSCPServer is deleted
252 - hard close of all sockets on exit
253 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
254 driver
255
256 * Bug fixes:
257 - fixed a crash which occurs when removing a sampler channel waiting
258 to start instrument loading after another channel
259 - fixed a crash which occurs when removing a sampler channel with
260 instrument loading in progress (bug #113)
261 - fixed termination caused by uncaught exception when adding MIDI
262 instrument with PERSISTENT load mode
263 - fixed possible iterator invalidations when resetting the sampler
264 - fixed memory leaks when issuing the following LSCP commands:
265 GET AUDIO_OUTPUT_DRIVER INFO
266 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
267 GET MIDI_INPUT_DRIVER INFO
268 GET MIDI_INPUT_DRIVER_PARAMETER INFO
269 - fixed possible compilation error when sqlite is not present
270 - fixed orphaned pointers when setting maximum voices limit (bug #118)
271 - fixed crash when changing the audio output device of a sampler
272 channel with loaded instrument and start playing notes
273 - fixed endless loop in Engine::SuspendAll() (bug #120)
274 - fixed a low-level atomic load function that was broken on 64-bit
275 PowerPC, which probably could cause crashes on that platform
276 - fixed a memory management error which could cause a crash when a
277 plugin was unloaded
278 - bugfix: two private structs had the same name, which could cause
279 problems if the linker chose the wrong constructor
280 - fixed low-level ConditionServer usage bug that caused lockups on
281 Windows
282
283
284 Version 0.5.1 (6 December 2007)
285
286 * packaging changes:
287 - added autoconf checks for pthread library
288 - added autoconf check for pthread bug found on certain NPTL-enabled
289 glibc versions (see Gentoo bug report #194076)
290 - added autoconf checks for MS Windows
291
292 * general changes:
293 - bugfix: the thread used by an editor plugin didn't die when the
294 editor closed
295 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
296 out all the space. operator--() did not apply size_mask after
297 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
298 order to avoid problems with the _NonVolatileReader functions.
299 - bugfix: Stream.h: added a missing divide by BytesPerSample in
300 GetWriteSpace(). Since this function is currently only used in
301 the stream's qsort() compare function, it didn't trigger any
302 bugs.
303 - Resampler.h, Synthesizer.h: cubic interpolation now works in
304 24bit mode too. Faster method to read 24bit words on little
305 endian machines (x86): replaced 3 byte reads + shifts with a 1
306 unaligned 32bit read and shift
307 - experimental support for MS Windows (MIDI input via MME, AUDIO
308 output via ASIO)
309 - made handling of SIGINT signal (Ctrl-C) a bit more robust
310 - support for monitoring the total number of active disk streams
311 (new LSCP commands: GET TOTAL_STREAM_COUNT,
312 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
313
314 * AUDIO driver:
315 - added Windows ASIO low latency audio driver
316
317 * MIDI driver:
318 - added MME Windows MIDI driver
319
320 * LSCP server:
321 - added support for Windows style path / filenames, however with
322 forward slash path separators instead of backslash
323 (i.e. "C:/foo/bar.gig")
324 - allow naughty liblscp to send non-string device parameters within
325 apostrophes as well
326 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
327 "LIST FILE INSTRUMENTS <file>" and
328 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
329 about an arbitrary instrument file on the system where the sampler is
330 running on
331
332 Version 0.5.0 (15 October 2007)
333
334 * packaging changes:
335 - config.h is not going to be installed along with liblinuxsampler's
336 API header files anymore
337 - only the API relevant header (and source) files will be exported to
338 the Doxygen API documentation (explicitly listed in Doxyfile.in)
339 - added completely new XCode project files for Mac OSX which is now
340 capable to execute our autoconf environment, thus no need anymore
341 to maintain the compile time configuration file (osx/version.h) for
342 OSX manually (patch by Toshi Nagata)
343 - fixed buggy boolean --enable-foo / --disable-foo configure script
344 parameters
345 - global.h now only covers global definitions that are needed for the
346 C++ API header files, all implementation internal global definitions
347 are now in global_private.h
348 - atomic.h is not exposed to the C++ API anymore
349 - no need to include config.h anymore for using LS's API header files
350 - fixed warnings in API doc generation
351
352 * general changes:
353 - replaced the old, confusing MIDI program change mechanism by a
354 flexible MIDI instrument mapper which allows to map arbitrary
355 (MIDI bank, MIDI program) pairs with arbitrary
356 (engine type, instrument file, file index) triplets which will be
357 loaded on the respective channel when such MIDI program change
358 messages arrive, beside that, each entry allows to define a life-time
359 strategy for the instrument, so the user can define whether the
360 instrument should i.e. be permanently loaded (to be able to switch
361 quickly among sounds) or i.e. loaded just on demand when the
362 respective program change arrives (to safe RAM space), as well as a
363 global volume factor for each entry, so the user can adjust the volume
364 dynamic of his mapped instrument collection without having to modify
365 the instrument files, also one can manage arbitrary amount of such
366 MIDI instrument maps and assign each sampler channel individually
367 a certain map, so that i.e. separation of normal instruments and
368 drumkits is possible
369 - new notification events for tracking changes to audio/MIDI devices,
370 MIDI instrument maps, MIDI instruments, FX sends, global volume.
371 - sampler was limited to load max. 200 instruments in the background
372 due to a constant size RingBuffer FIFO which is now replaced by a
373 dynamic (unlimited) size std::list FIFO
374 - added FX sends, these allow to route audio signals to arbitrary audio
375 output channels for being processed by external effect processors
376 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
377 controllers
378 - global (sampler wide) volume can now be controlled at runtime
379 - Implemented new, improved notification system
380 - fixed compilation errors regarding OSX
381 (patch by Toshi Nagata)
382 - implemented instruments database
383 - added support for escape sequences to the instruments database
384 - added highly experimental support for on-the-fly instrument editing
385 within the sampler's process (by using instrument editor plugins),
386 you'll notice the new "Registered instrument editors:" message on
387 startup, added a new LSCP command:
388 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
389 to spawn a matching instrument editor for the instrument on the
390 given sampler channel, the plugin path can be overridden at compile
391 time with ./configure --enable-plugin-dir=/some/dir
392 - added experimental code for synchronizing instrument editors hosted
393 in the sampler's process to safely edit instruments while playing
394 without a crash (hopefully) by either suspending single regions
395 wherever possible or if unavoidable whole engine(s)
396 - fixed several issues in fundamental "Thread" class: set scheduling
397 policy and priority on thread level, set a minimum stack size for
398 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
399 threads simply inherited properties of starting thread instead of
400 setting their own policy and priority
401 - minor fix in our automatic stack trace mechanism on crashes, the
402 main process did not wait for the stack trace process to finish
403 its output
404 - fixed some minor memory leaks
405 - reenabled assembly features support, at the moment only for
406 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
407 - minor assembly fix in x86 features detection (don't use the PIC
408 register, to avoid relocations in the text segment at runtime)
409 - POSIX callback functions of Thread.h are hidden
410
411 * MIDI driver:
412 - dispatch bank select (MSB and LSB) messages
413
414 * audio driver:
415 - the ALSA audio output driver parameters now reflect the correct
416 parameter value ranges for the respective selected sound card
417 (patch by Till Wimmer, a bit fixed and extended)
418
419 * Gigasampler format engine:
420 - if a filter is used and EG2 finishes before EG1, let the voice
421 die when EG2 has finished (this fixes a problem with clicks and
422 voice starvation for some gigs)
423 - playback is no longer disabled during instrument loading
424 - all notes playing on a channel that changes its instrument keep
425 playing with the old instrument until they get a note off
426 command
427 - EG fix: a release value of zero could cause noises or crash
428 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
429 - EG fine tuning: when attack is zero the EG starts at a level
430 above max sustain level, which means that there is a decay phase
431 even if sustain is 100%
432 - more EG fixes: the level could sometimes go below zero and cause
433 noises or crashes
434 - minor fix of EGDecay (patch by Toshi Nagata)
435 - fixed compiler error when --enable-override-filter-type was
436 supplied to the configure script (fixes #46)
437 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
438 instead of a fix value
439 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
440 127 (solo mode) only kill voices if the respective mode really
441 changed
442
443 * LSCP server:
444 - fixed compile time error for old Bison versions
445 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
446 - parser now supports extended ASCII character set
447 (up to ASCII code 255, i.e. includes now umlauts and accents)
448 - filename arguments in LSCP commands now allow to use escape
449 sequences, that is directly literal as one of: \', \", \\, \n, \r,
450 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
451 code value like \xf2) (fixes bug #24)
452 - the following LSCP commands now also support escape sequences for at
453 least one of their text-based parameters (i.e. name, description):
454 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
455 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
456 "SET DB_INSTRUMENT_DIRECTORY NAME",
457 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
458 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
459 "FIND DB_INSTRUMENT_DIRECTORIES"
460 - returns verbose syntax errors (line and column where syntax error
461 occured, the unexpected character and the actually expected, possible
462 character(s), the latter only if less than 5 possibilities)
463 - made sure that LSCP syntax is not affected by gigedit locale
464 settings
465 - bugfix regarding strings parameter lists: all comma separated lists
466 of strings were treated as being one string containing commas
467 (fixes #57)
468
469 * Bug fixes:
470 - fixed crash occurring on certain LSCP scripts (Bug 39)
471 - another thread safety fix for lscp "load engine" and "set
472 channel audio output device"
473 - fixed a crash which occurs when reassigning the same engine
474 on a sampler channel with connected MIDI device
475 - fixed a crash which occurs when changing the number of ports of a MIDI
476 device connected to a sampler channel to number less then or equal
477 to the index of the port to which the sampler channel is connected.
478 - The previous bindings were not been disconnected when altering
479 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
480 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
481 - The active stream/voice count statistic was incorrect.
482 - notification events were not been sent for some sampler
483 channel changes
484 - added default min and max values to restrict the number of allowed
485 audio output channels and MIDI input ports
486 - the connection to the PCM interface is now closed when destroying
487 an audio output device
488 - files with slash in their path or filename could not be loaded
489
490 * test cases:
491 - updated and fixed (haven't been touched in a while)
492
493 Version 0.4.0 (24 November 2006)
494
495 * packaging changes:
496 - changed deprecated copyright attribute to license; added ldconfig
497 to post-(un)install steps; added devel package for liblinuxsampler;
498 to linuxsampler.spec (RPM)
499 - install necessary development header files for allowing 3rd party
500 applications to link against liblinuxsampler
501 - liblinuxsampler's API documentation can be generated with 'make docs'
502 (Doxygen required)
503 - added benchmark to automatically detect the best triangle LFO
504 implementation (currently either an integer math solution or a
505 di-harmonic approximation), automatic detection can be overriden
506 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
507 configure script argument though (mandatory for cross-compilation)
508 - do not automatically pick optimized gcc flags if the user already
509 provided some on his own (as CXXFLAGS)
510 - added compile time option to disable processing of All-Notes-Off MIDI
511 messages
512 - added compile time options to allow disabling the various audio and
513 MIDI drivers
514 - fixed automatic GCC CPU switch detection on PPC
515 (patch by Ebrahim Mayat)
516
517 * Gigasampler format engine:
518 - extensive synthesis optimization
519 (reimplementation of EGs and LFO(s), removed synthesis parameter
520 prerendering and the synthesis parameter matrix in general, splitting
521 each audio fragment into subfragments now where each subfragment uses
522 constant pitch and filter coefficients. The volume coefficient is
523 linearly interpolated inside a subfragment, unless
524 --disable-interpolate-volume is set.)
525 - fine tuning of the EG modulation parameters
526 - improved filter cutoff calculation by adding support for the
527 following gig parameters: Cutoff freq (used when no cutoff
528 controller is defined), Control invert, Minimum cutoff, Velocity
529 curve and Velocity range. The keyboard tracking now scales
530 cutoff frequency instead of resonance.
531 - added support for gig parameter Resonance.
532 - fixed bug in sysex handling (patch by Juan Linietsky)
533 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
534 which can be overridden with --enable-global-attenuation
535 - EG fixes: made the length of "attack hold" stage more
536 accurate. Release stage can now start before attack stage
537 ends. Cancel release didn't work when sustain was zero. Attack
538 time now has a minimal value to prevent clicks.
539 - fixed pitch changes larger than one octave
540 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
541 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
542 all modes can be altered via standard GM messages, that is CC5 for
543 altering portamento time, CC65 for enabling / disabling portamento
544 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
545 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
546 parameter) and crossfade
547 - added support for the "attenuation controller threshold" gig
548 parameter
549 - added smoothing of volume changes caused by control change
550 messages
551 - sample loop parameters are now taken from the DimensionRegion
552 instead of the wave chunk
553 - fixed keyswitching for v3 gigs with a number of keyswitch splits
554 not equal to a power of two
555 - reimplementation of the filter algorithm. The new filter is more
556 accurate and supports all gig filter types, including bandreject
557 and lowpass turbo.
558 - real support for 24 bit samples - samples are not truncated to
559 16 bits anymore
560 - support for aftertouch (channel pressure, not polyphonic
561 aftertouch)
562 - LFO1 behaviour fixed (dampening from max volume instead of
563 amplifying from 0)
564
565 * LSCP server:
566 - fixed application exit on broken pipe error (fixes bug #20)
567 - fixed the notification messages delay due to lack of
568 network activity (fixes bug #26)
569 - fixed parser bug which occured on space(s) within device parameters
570 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
571
572 * audio driver:
573 - added aRts audio output driver (by no means RT safe)
574
575 * MIDI driver:
576 - fixed legacy sysex code which caused dispatching of MIDI SysEx
577 messages several times instead of once
578 - API extension for MIDI drivers which already supply exact time stamps
579 for events (i.e. for offline rendering based MIDI drivers)
580 - added checks for bad MIDI data
581
582 * linuxsampler application:
583 - show available sampler engine types on startup
584
585 * general changes:
586 - support for muting sampler channels and solo mode of the same, two new
587 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
588 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
589 introduced for this, the behavior is the same like on a mixer console
590 (patch by Grigor Iliev, a bit adjusted). Also added configure option
591 --enable-process-muted-channels which can be used to enable the
592 processing of muted channels.
593 - support for sostenuto pedal
594 - support for monitoring the total number of active voices
595 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
596 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
597 - fixed some memory management errors
598 - fixed some concurrency problems that could lead to crashes when
599 LSCP commands were executed
600 - fixed crash when instrument loading failed previously on the same
601 sampler channel (fixes bug #36)
602
603 Version 0.3.3 (15 July 2005)
604
605 * packaging changes:
606 - fixed compilation with gcc 4.0
607
608 * Gigasampler format engine:
609 - LFO preprocessing was performed even though the respective LFO was
610 disabled by the instrument patch (minor efficiency fix)
611 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
612 for volume ramp downs in the same fragment (needed for current voice
613 stealing implementation) then simply inform the user with a warning
614 about possible click sounds and reduce the volume ramp down
615 appropriately instead of cancelling the audio device connection
616
617 Version 0.3.2 (24 June 2005)
618
619 * packaging changes:
620 - updated autotools build files to compile on OS X
621 (conditional compilation of CoreMIDI and MidiShare drivers)
622 - hand-crafted assembly optimization code can be disabled with
623 './configure --disable-asm' (definitely not recommended)
624 - fixed 'make dist' rule to include all necessary files
625 - require automake (>= 1.5) for 'make -f Makefile.cvs'
626 (due to 'dist-bzip2' automake option)
627
628 * Gigasampler format engine:
629 - support for the gig parameters for "release velocity response" curves
630 - fine tuning of the EGADSR envelope
631 - volume of release triggered samples now depends on note-on velocity,
632 note length and gig parameter "release trigger decay" instead of
633 note-off velocity.
634 - revised voice stealing
635 (fixes crash and endless loop caused by voice stealing)
636 - don't reset scale tuning on instrument or audio output device change
637 - handle key group conflicts right at the beginning of each fragment
638 instead of when the respective voice is actually launched
639 (fixes undefined behavior if stolen voices belonged to a key group -
640 this case was followed by a "killed voice survived" error message)
641 - fixed minor issue with null/silence samples
642 (those stole voices even though they don't need a voice at all which
643 resulted in "voice stealing didn't work out" messages)
644 - don't reset volume, pan, pitch and MIDI controller values on
645 instrument or audio output device change
646
647 * LSCP server:
648 - fixed some crashes (patch by Grigor Iliev, fixes #19)
649 - fixed LSCP event "CHANNEL_INFO" notification
650 (e.g. did not notify on volume changes or MIDI program change events)
651
652 * linuxsampler application:
653 - added command line parameters --lscp-addr and --lscp-port to override
654 default IP address and port of LSCP server
655
656 Version 0.3.1 (24 May 2005)
657
658 * initial release
