File size: 34001 byte(s)
* sfz engine: reduced memory usage for sfz data

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)
40 - added support for amp_veltrack and amp_velcurve_N
41 - fine-tuned the default velocity curve
42 - added support for transpose
43 - fixed crash when using sw_down/up
44 - improved logic for sw_lokey/hikey/up/down/last
45 - added more v1 aliases to parser
46 - reduced memory usage for sfz data
47
48 * SoundFont format engine:
49 - Initial implementation (not usable yet)
50
51 * Host plugins:
52 - AU bugfix: failed to destroy its audio/MIDI devices
53 - Listen to all interfaces on Mac OS X (INADDR_ANY)
54 - VST bugfix: If the host called resume() before and after
55 changing sample rate or block size, the number of channels was
56 incorrectly set to two. This caused silence in Cubase 5.
57
58 * MIDI driver:
59 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
60 the ALSA sequencer client name
61
62 * LSCP server:

67 - Fixed crash which may occur when MIDI key + transpose is out of range
68
69 Version 1.0.0 (31 July 2009)
70
71 * packaging changes:
72 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
73 causing e.g. the libgig test to fail when
74 "./configure --disable-jack-driver" was used
75 (patch by Alexis Ballier)
76 - fixed compilation with gcc 4.3
77 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
78 - fixed configure so it detects x86_64 (#107)
79 - fixes for building with newer MinGW versions
80 - fix for building with bison 2.4 (#111)
81 - fixed building with libgig installed in a non-standard directory
82 - minor fix in configure for mmsystem.h detection on MinGW
83 - Windows: look for editor plugins and Fantasia using base
84 directory of liblinuxsampler dll (look in the same directory and one
85 directory above)
86 - configure script fix: removed unconditional use of SSE
87 - fixed building with sqlite installed in a non-standard directory
88 - when cross-compiling, don't try to create instruments.db
89 - fix for new mingw-w64 version, which has usleep
90
91 * general changes:
92 - bugfix: on some POSIX systems instrument editor plugins refused to
93 load as we used a non-portable Linux specific struct field
94 (fixes bug #70, patch by Ronald Baljeu)
95 - fixed endless loop which occured when loading an instrument editor
96 plugin DLL on Windows systems failed
97 - fixed memory leaks that occurred when liblinuxsampler was unloaded
98 - optimized the SynchronizedConfig class so it doesn't wait
99 unnecessarily long after an update
100 - added support for notifying instrument editors on note-on / note-off
101 events (e.g. to highlight the pressed keys on the virtual keyboard
102 of gigedit)
103 - added support for triggering notes by instrument editors (see above)
104 - be verbose on DLL load errors (on Linux)
105 - fixed di-harmonic triangle LFO implementation (this LFO implementation
106 is only used by very few systems, most pick the int math
107 implementation, which is usually faster)
108 - fixes for audio drivers with varying buffer sizes
109 - experimental support for running LinuxSampler as a DSSI, LV2 and
110 VST plugin
111 - notification events for stream/voice count statistics are now sent
112 only when there are actual changes
113 - added memory ordering constraints to improve stability on
114 multi-core and multi-cpu systems
115 - maximum voices and disk streams can now be altered at runtime
116 - fixed CPU feature detection on x86_64 (maybe fixes #108)
117 - automatic stacktrace mechanism is now turned off by default and can
118 be switched on by command line option "--stacktrace" (the automatic
119 stacktrace mechanism seems to be broken on most systems at the moment)
120 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
121 a pointer to the launched InstrumentEditor object
122 - added optional 3rd party user data parameter for following
123 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
124 InstrumentEditor::Launch(),
125 InstrumentManager::LaunchInstrumentEditor()
126 - theoretical fix: made SynchronizedConfig follow C++0x memory
127 model more strictly
128 - fixes for using large audio device buffers
129 - Windows: add the installation directory to the DLL search path
130 when loading an editor plugin (solves problems with VST and
131 gigedit on systems with other GTK versions installed)
132
133 * audio driver:
134 - removed the nonsense audio channel constraint (which was hard coded to
135 max. 100 audio channels) for most audio drivers
136 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
137 opposed to the LSCP specs
138 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
139 reflected the wrong value
140 - fixed a memory management bug in ASIO driver
141 - Makefile fix: JACK_CFLAGS wasn't used
142 - JACK: use jack_client_open instead of the deprecated
143 jack_client_new
144 - added (experimental) CoreAudio driver
145 - applied old fixes to the ASIO driver that were included in the
146 previous binary release but accidentally never committed to CVS
147 (fixes #117)
148 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
149 win64)
150 - VST: added support for sample rate and buffer size changes
151 - VST: close editor (Fantasia) when the VST is removed
152 - VST: avoid opening Fantasia more than once for each VST instance
153 - VST: export main function as "main" on Linux too (fix for
154 energyXT)
155 - VST: changed number of output channels from one stereo to 16
156 stereo
157 - added channel routing, fxsends and midi maps to the settings
158 stored in the plugin state
159 - performance optimization of AudioChannel::MixTo() and
160 AudioChannel::CopyTo() methods using GCC vector exensions
161 (if available)
162 - ASIO fixes: avoid initializing the device twice, avoid throwing
163 exception when getting parameters from a disconnected device
164
165 * MIDI driver:
166 - added JACK MIDI driver
167 - dispatch bank select as ordinary CC as well, the user might seriously
168 want to (mis)use it for some purpose ("fixed" in all current MIDI
169 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
170 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
171 CoreMidi or AU
172 - fixed mingw-w64 compilation error in MME driver
173 - made program change handling in MIDI thread real-time safe by
174 moving the logic to a non-RT thread
175 - fixed minor memory leak in ALSA driver
176
177 * instruments database:
178 - avoid time consuming samples scanning when adding instruments
179 to the instruments database
180 - added support for handling lost files in the instruments database
181 - Implemented option for adding instruments in separate directories
182 in the instruments database
183 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
184 - work-around for missing fnmatch function on Windows to make
185 instrument database compilable
186 - added instrument database support on Windows
187 works with both standalone mode and VST plugin.
188 the instruments DB file is located in
189 %USERPROFILE%\.linuxsampler\instruments.db which allows different
190 databases for each windows user
191 if no DB is present it automatically creates the .linuxsampler subdir
192 and then creates an empty DB
193 - fixed recursive import, which was broken on Windows
194
195 * Gigasampler format engine:
196 - fixed a memory leak that could happen when a channel was deleted
197 while notes were playing
198 - made it possible to load an instrument even if the audio thread
199 isn't running
200 - added partial support for the "Controller Triggered" MIDI rule,
201 enough for piano gigs with pedal noise samples
202 - minor fix: only mark FX sends as being modified if really the
203 respective FX send MIDI controller was used
204 - added support for GM global device volume SysEx message
205 (can be selected at compile time to either apply globally to the
206 whole sampler [default] or only to the sampler channels that are
207 connected to the respective MIDI input port the SysEx message arrived
208 on)
209 - bugfix: notes triggered at position 0 in the audio buffer were
210 sometimes wrongly killed in the same buffer, causing no sound to
211 be played
212 - added support for chromatic / drumkit mode Roland GS Sysex message
213 which is usally used to switch a part between chromatic sounds and
214 drumkit sounds (as opposed to their common default setting of MIDI
215 part 10 being a drumkit part and all other ones chromatic parts), in
216 LS however one can switch between the first 16 MIDI instrument maps
217 defined for the sampler
218 - made it possible to create multiple sample channels even if the
219 audio thread isn't running
220 - fixed crash when removing channel with active voices (#116)
221 - bugfix: on sample reference changes (instrument editor), only
222 un-cache the respective sample if it's really not used by any
223 sampler engine anymore
224 - re-cache samples in case they were changed by an instrument editor,
225 e.g. when a sample was added while playing (#82)
226 - fixed hanging notes which occured when note-off event had the exact
227 same time stamp as the voice's note-on event and occured both in the
228 same audio fragment cycle (fixes bug #112)
229 - added support for the "fine tune" and "pitch bend range"
230 instrument-level gig parameters
231 - fixed minor artifacts in pitch bend handling
232 - added support for GS Reset SysEx message
233 - allow gig files to use unlimited downward pitch shifting
234 - added a limit check for upward pitch shifting
235 - bugfix: sometimes, when playing a note twice fast, the second
236 note was silent
237 - fixed crash happening when a pitch bend event arrived at the
238 same time a new instrument was loading
239
240 * LSCP server:
241 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
242 react on MIDI data arriving on certain sampler channels (so far only
243 Note-On and Note-Off events are sent via this LSCP event)
244 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
245 react on MIDI data arriving on certain MIDI input devices (so far only
246 Note-On and Note-Off events are sent via this LSCP event)
247 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
248 SET DB_INSTRUMENT FILE_PATH
249 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
250 frontends to send MIDI messages to specific sampler channel
251 - added two additional fields to GET FILE INSTRUMENT INFO command -
252 KEY_BINDINGS and KEYSWITCH_BINDINGS
253 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
254 was incorrect
255 - Optimized the retrieval of the MIDI instrument mappings
256 - added new LSCP command "SET VOICES" to globally alter the maximum
257 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
258 be triggered respectively
259 - added new LSCP command "SET STREAMS" to globally alter the maximum
260 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
261 which will be triggered respectively
262 - bugfix: retry if "select" returns EINTR (this fixes a crash when
263 a gigedit file dialog is opened)
264 - close all connections when LSCPServer is deleted
265 - hard close of all sockets on exit
266 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
267 driver
268
269 * Bug fixes:
270 - fixed a crash which occurs when removing a sampler channel waiting
271 to start instrument loading after another channel
272 - fixed a crash which occurs when removing a sampler channel with
273 instrument loading in progress (bug #113)
274 - fixed termination caused by uncaught exception when adding MIDI
275 instrument with PERSISTENT load mode
276 - fixed possible iterator invalidations when resetting the sampler
277 - fixed memory leaks when issuing the following LSCP commands:
278 GET AUDIO_OUTPUT_DRIVER INFO
279 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
280 GET MIDI_INPUT_DRIVER INFO
281 GET MIDI_INPUT_DRIVER_PARAMETER INFO
282 - fixed possible compilation error when sqlite is not present
283 - fixed orphaned pointers when setting maximum voices limit (bug #118)
284 - fixed crash when changing the audio output device of a sampler
285 channel with loaded instrument and start playing notes
286 - fixed endless loop in Engine::SuspendAll() (bug #120)
287 - fixed a low-level atomic load function that was broken on 64-bit
288 PowerPC, which probably could cause crashes on that platform
289 - fixed a memory management error which could cause a crash when a
290 plugin was unloaded
291 - bugfix: two private structs had the same name, which could cause
292 problems if the linker chose the wrong constructor
293 - fixed low-level ConditionServer usage bug that caused lockups on
294 Windows
295
296
297 Version 0.5.1 (6 December 2007)
298
299 * packaging changes:
300 - added autoconf checks for pthread library
301 - added autoconf check for pthread bug found on certain NPTL-enabled
302 glibc versions (see Gentoo bug report #194076)
303 - added autoconf checks for MS Windows
304
305 * general changes:
306 - bugfix: the thread used by an editor plugin didn't die when the
307 editor closed
308 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
309 out all the space. operator--() did not apply size_mask after
310 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
311 order to avoid problems with the _NonVolatileReader functions.
312 - bugfix: Stream.h: added a missing divide by BytesPerSample in
313 GetWriteSpace(). Since this function is currently only used in
314 the stream's qsort() compare function, it didn't trigger any
315 bugs.
316 - Resampler.h, Synthesizer.h: cubic interpolation now works in
317 24bit mode too. Faster method to read 24bit words on little
318 endian machines (x86): replaced 3 byte reads + shifts with a 1
319 unaligned 32bit read and shift
320 - experimental support for MS Windows (MIDI input via MME, AUDIO
321 output via ASIO)
322 - made handling of SIGINT signal (Ctrl-C) a bit more robust
323 - support for monitoring the total number of active disk streams
324 (new LSCP commands: GET TOTAL_STREAM_COUNT,
325 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
326
327 * AUDIO driver:
328 - added Windows ASIO low latency audio driver
329
330 * MIDI driver:
331 - added MME Windows MIDI driver
332
333 * LSCP server:
334 - added support for Windows style path / filenames, however with
335 forward slash path separators instead of backslash
336 (i.e. "C:/foo/bar.gig")
337 - allow naughty liblscp to send non-string device parameters within
338 apostrophes as well
339 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
340 "LIST FILE INSTRUMENTS <file>" and
341 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
342 about an arbitrary instrument file on the system where the sampler is
343 running on
344
345 Version 0.5.0 (15 October 2007)
346
347 * packaging changes:
348 - config.h is not going to be installed along with liblinuxsampler's
349 API header files anymore
350 - only the API relevant header (and source) files will be exported to
351 the Doxygen API documentation (explicitly listed in Doxyfile.in)
352 - added completely new XCode project files for Mac OSX which is now
353 capable to execute our autoconf environment, thus no need anymore
354 to maintain the compile time configuration file (osx/version.h) for
355 OSX manually (patch by Toshi Nagata)
356 - fixed buggy boolean --enable-foo / --disable-foo configure script
357 parameters
358 - global.h now only covers global definitions that are needed for the
359 C++ API header files, all implementation internal global definitions
360 are now in global_private.h
361 - atomic.h is not exposed to the C++ API anymore
362 - no need to include config.h anymore for using LS's API header files
363 - fixed warnings in API doc generation
364
365 * general changes:
366 - replaced the old, confusing MIDI program change mechanism by a
367 flexible MIDI instrument mapper which allows to map arbitrary
368 (MIDI bank, MIDI program) pairs with arbitrary
369 (engine type, instrument file, file index) triplets which will be
370 loaded on the respective channel when such MIDI program change
371 messages arrive, beside that, each entry allows to define a life-time
372 strategy for the instrument, so the user can define whether the
373 instrument should i.e. be permanently loaded (to be able to switch
374 quickly among sounds) or i.e. loaded just on demand when the
375 respective program change arrives (to safe RAM space), as well as a
376 global volume factor for each entry, so the user can adjust the volume
377 dynamic of his mapped instrument collection without having to modify
378 the instrument files, also one can manage arbitrary amount of such
379 MIDI instrument maps and assign each sampler channel individually
380 a certain map, so that i.e. separation of normal instruments and
381 drumkits is possible
382 - new notification events for tracking changes to audio/MIDI devices,
383 MIDI instrument maps, MIDI instruments, FX sends, global volume.
384 - sampler was limited to load max. 200 instruments in the background
385 due to a constant size RingBuffer FIFO which is now replaced by a
386 dynamic (unlimited) size std::list FIFO
387 - added FX sends, these allow to route audio signals to arbitrary audio
388 output channels for being processed by external effect processors
389 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
390 controllers
391 - global (sampler wide) volume can now be controlled at runtime
392 - Implemented new, improved notification system
393 - fixed compilation errors regarding OSX
394 (patch by Toshi Nagata)
395 - implemented instruments database
396 - added support for escape sequences to the instruments database
397 - added highly experimental support for on-the-fly instrument editing
398 within the sampler's process (by using instrument editor plugins),
399 you'll notice the new "Registered instrument editors:" message on
400 startup, added a new LSCP command:
401 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
402 to spawn a matching instrument editor for the instrument on the
403 given sampler channel, the plugin path can be overridden at compile
404 time with ./configure --enable-plugin-dir=/some/dir
405 - added experimental code for synchronizing instrument editors hosted
406 in the sampler's process to safely edit instruments while playing
407 without a crash (hopefully) by either suspending single regions
408 wherever possible or if unavoidable whole engine(s)
409 - fixed several issues in fundamental "Thread" class: set scheduling
410 policy and priority on thread level, set a minimum stack size for
411 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
412 threads simply inherited properties of starting thread instead of
413 setting their own policy and priority
414 - minor fix in our automatic stack trace mechanism on crashes, the
415 main process did not wait for the stack trace process to finish
416 its output
417 - fixed some minor memory leaks
418 - reenabled assembly features support, at the moment only for
419 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
420 - minor assembly fix in x86 features detection (don't use the PIC
421 register, to avoid relocations in the text segment at runtime)
422 - POSIX callback functions of Thread.h are hidden
423
424 * MIDI driver:
425 - dispatch bank select (MSB and LSB) messages
426
427 * audio driver:
428 - the ALSA audio output driver parameters now reflect the correct
429 parameter value ranges for the respective selected sound card
430 (patch by Till Wimmer, a bit fixed and extended)
431
432 * Gigasampler format engine:
433 - if a filter is used and EG2 finishes before EG1, let the voice
434 die when EG2 has finished (this fixes a problem with clicks and
435 voice starvation for some gigs)
436 - playback is no longer disabled during instrument loading
437 - all notes playing on a channel that changes its instrument keep
438 playing with the old instrument until they get a note off
439 command
440 - EG fix: a release value of zero could cause noises or crash
441 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
442 - EG fine tuning: when attack is zero the EG starts at a level
443 above max sustain level, which means that there is a decay phase
444 even if sustain is 100%
445 - more EG fixes: the level could sometimes go below zero and cause
446 noises or crashes
447 - minor fix of EGDecay (patch by Toshi Nagata)
448 - fixed compiler error when --enable-override-filter-type was
449 supplied to the configure script (fixes #46)
450 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
451 instead of a fix value
452 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
453 127 (solo mode) only kill voices if the respective mode really
454 changed
455
456 * LSCP server:
457 - fixed compile time error for old Bison versions
458 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
459 - parser now supports extended ASCII character set
460 (up to ASCII code 255, i.e. includes now umlauts and accents)
461 - filename arguments in LSCP commands now allow to use escape
462 sequences, that is directly literal as one of: \', \", \\, \n, \r,
463 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
464 code value like \xf2) (fixes bug #24)
465 - the following LSCP commands now also support escape sequences for at
466 least one of their text-based parameters (i.e. name, description):
467 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
468 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
469 "SET DB_INSTRUMENT_DIRECTORY NAME",
470 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
471 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
472 "FIND DB_INSTRUMENT_DIRECTORIES"
473 - returns verbose syntax errors (line and column where syntax error
474 occured, the unexpected character and the actually expected, possible
475 character(s), the latter only if less than 5 possibilities)
476 - made sure that LSCP syntax is not affected by gigedit locale
477 settings
478 - bugfix regarding strings parameter lists: all comma separated lists
479 of strings were treated as being one string containing commas
480 (fixes #57)
481
482 * Bug fixes:
483 - fixed crash occurring on certain LSCP scripts (Bug 39)
484 - another thread safety fix for lscp "load engine" and "set
485 channel audio output device"
486 - fixed a crash which occurs when reassigning the same engine
487 on a sampler channel with connected MIDI device
488 - fixed a crash which occurs when changing the number of ports of a MIDI
489 device connected to a sampler channel to number less then or equal
490 to the index of the port to which the sampler channel is connected.
491 - The previous bindings were not been disconnected when altering
492 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
493 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
494 - The active stream/voice count statistic was incorrect.
495 - notification events were not been sent for some sampler
496 channel changes
497 - added default min and max values to restrict the number of allowed
498 audio output channels and MIDI input ports
499 - the connection to the PCM interface is now closed when destroying
500 an audio output device
501 - files with slash in their path or filename could not be loaded
502
503 * test cases:
504 - updated and fixed (haven't been touched in a while)
505
506 Version 0.4.0 (24 November 2006)
507
508 * packaging changes:
509 - changed deprecated copyright attribute to license; added ldconfig
510 to post-(un)install steps; added devel package for liblinuxsampler;
511 to linuxsampler.spec (RPM)
512 - install necessary development header files for allowing 3rd party
513 applications to link against liblinuxsampler
514 - liblinuxsampler's API documentation can be generated with 'make docs'
515 (Doxygen required)
516 - added benchmark to automatically detect the best triangle LFO
517 implementation (currently either an integer math solution or a
518 di-harmonic approximation), automatic detection can be overriden
519 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
520 configure script argument though (mandatory for cross-compilation)
521 - do not automatically pick optimized gcc flags if the user already
522 provided some on his own (as CXXFLAGS)
523 - added compile time option to disable processing of All-Notes-Off MIDI
524 messages
525 - added compile time options to allow disabling the various audio and
526 MIDI drivers
527 - fixed automatic GCC CPU switch detection on PPC
528 (patch by Ebrahim Mayat)
529
530 * Gigasampler format engine:
531 - extensive synthesis optimization
532 (reimplementation of EGs and LFO(s), removed synthesis parameter
533 prerendering and the synthesis parameter matrix in general, splitting
534 each audio fragment into subfragments now where each subfragment uses
535 constant pitch and filter coefficients. The volume coefficient is
536 linearly interpolated inside a subfragment, unless
537 --disable-interpolate-volume is set.)
538 - fine tuning of the EG modulation parameters
539 - improved filter cutoff calculation by adding support for the
540 following gig parameters: Cutoff freq (used when no cutoff
541 controller is defined), Control invert, Minimum cutoff, Velocity
542 curve and Velocity range. The keyboard tracking now scales
543 cutoff frequency instead of resonance.
544 - added support for gig parameter Resonance.
545 - fixed bug in sysex handling (patch by Juan Linietsky)
546 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
547 which can be overridden with --enable-global-attenuation
548 - EG fixes: made the length of "attack hold" stage more
549 accurate. Release stage can now start before attack stage
550 ends. Cancel release didn't work when sustain was zero. Attack
551 time now has a minimal value to prevent clicks.
552 - fixed pitch changes larger than one octave
553 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
554 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
555 all modes can be altered via standard GM messages, that is CC5 for
556 altering portamento time, CC65 for enabling / disabling portamento
557 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
558 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
559 parameter) and crossfade
560 - added support for the "attenuation controller threshold" gig
561 parameter
562 - added smoothing of volume changes caused by control change
563 messages
564 - sample loop parameters are now taken from the DimensionRegion
565 instead of the wave chunk
566 - fixed keyswitching for v3 gigs with a number of keyswitch splits
567 not equal to a power of two
568 - reimplementation of the filter algorithm. The new filter is more
569 accurate and supports all gig filter types, including bandreject
570 and lowpass turbo.
571 - real support for 24 bit samples - samples are not truncated to
572 16 bits anymore
573 - support for aftertouch (channel pressure, not polyphonic
574 aftertouch)
575 - LFO1 behaviour fixed (dampening from max volume instead of
576 amplifying from 0)
577
578 * LSCP server:
579 - fixed application exit on broken pipe error (fixes bug #20)
580 - fixed the notification messages delay due to lack of
581 network activity (fixes bug #26)
582 - fixed parser bug which occured on space(s) within device parameters
583 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
584
585 * audio driver:
586 - added aRts audio output driver (by no means RT safe)
587
588 * MIDI driver:
589 - fixed legacy sysex code which caused dispatching of MIDI SysEx
590 messages several times instead of once
591 - API extension for MIDI drivers which already supply exact time stamps
592 for events (i.e. for offline rendering based MIDI drivers)
593 - added checks for bad MIDI data
594
595 * linuxsampler application:
596 - show available sampler engine types on startup
597
598 * general changes:
599 - support for muting sampler channels and solo mode of the same, two new
600 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
601 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
602 introduced for this, the behavior is the same like on a mixer console
603 (patch by Grigor Iliev, a bit adjusted). Also added configure option
604 --enable-process-muted-channels which can be used to enable the
605 processing of muted channels.
606 - support for sostenuto pedal
607 - support for monitoring the total number of active voices
608 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
609 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
610 - fixed some memory management errors
611 - fixed some concurrency problems that could lead to crashes when
612 LSCP commands were executed
613 - fixed crash when instrument loading failed previously on the same
614 sampler channel (fixes bug #36)
615
616 Version 0.3.3 (15 July 2005)
617
618 * packaging changes:
619 - fixed compilation with gcc 4.0
620
621 * Gigasampler format engine:
622 - LFO preprocessing was performed even though the respective LFO was
623 disabled by the instrument patch (minor efficiency fix)
624 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
625 for volume ramp downs in the same fragment (needed for current voice
626 stealing implementation) then simply inform the user with a warning
627 about possible click sounds and reduce the volume ramp down
628 appropriately instead of cancelling the audio device connection
629
630 Version 0.3.2 (24 June 2005)
631
632 * packaging changes:
633 - updated autotools build files to compile on OS X
634 (conditional compilation of CoreMIDI and MidiShare drivers)
635 - hand-crafted assembly optimization code can be disabled with
636 './configure --disable-asm' (definitely not recommended)
637 - fixed 'make dist' rule to include all necessary files
638 - require automake (>= 1.5) for 'make -f Makefile.cvs'
639 (due to 'dist-bzip2' automake option)
640
641 * Gigasampler format engine:
642 - support for the gig parameters for "release velocity response" curves
643 - fine tuning of the EGADSR envelope
644 - volume of release triggered samples now depends on note-on velocity,
645 note length and gig parameter "release trigger decay" instead of
646 note-off velocity.
647 - revised voice stealing
648 (fixes crash and endless loop caused by voice stealing)
649 - don't reset scale tuning on instrument or audio output device change
650 - handle key group conflicts right at the beginning of each fragment
651 instead of when the respective voice is actually launched
652 (fixes undefined behavior if stolen voices belonged to a key group -
653 this case was followed by a "killed voice survived" error message)
654 - fixed minor issue with null/silence samples
655 (those stole voices even though they don't need a voice at all which
656 resulted in "voice stealing didn't work out" messages)
657 - don't reset volume, pan, pitch and MIDI controller values on
658 instrument or audio output device change
659
660 * LSCP server:
661 - fixed some crashes (patch by Grigor Iliev, fixes #19)
662 - fixed LSCP event "CHANNEL_INFO" notification
663 (e.g. did not notify on volume changes or MIDI program change events)
664
665 * linuxsampler application:
666 - added command line parameters --lscp-addr and --lscp-port to override
667 default IP address and port of LSCP server
668
669 Version 0.3.1 (24 May 2005)
670
671 * initial release
