Sun Apr 11 10:20:24 2010 UTC (13 years, 11 months ago) by persson
File size: 33730 byte(s)
* sfz engine: added support for amp_veltrack and amp_velcurve_N.
  Fine-tuned the default velocity curve.

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 trigger=first, trigger=legato and sw_previous
27 - allow non-numerical key values ("C#4" for example)
28 - "key" opcode now sets pitch_keycenter too
29 - fixed error when unloading instrument with same sample used by
30 multiple regions
31 - added some opcode aliases, like loopmode for loop_mode, to be
32 more compatible
33 - added support for trigger=release and rt_decay
34 - added support for off_mode=normal
35 - added support for random, seq_position, seq_length and volume
36 - added v1 LFO opcodes to parser (no support in engine yet)
37 - added support for amp_veltrack and amp_velcurve_N
38 - fine-tuned the default velocity curve
39
40 * SoundFont format engine:
41 - Initial implementation (not usable yet)
42
43 * Host plugins:
44 - AU bugfix: failed to destroy its audio/MIDI devices
45 - Listen to all interfaces on Mac OS X (INADDR_ANY)
46 - VST bugfix: If the host called resume() before and after
47 changing sample rate or block size, the number of channels was
48 incorrectly set to two. This caused silence in Cubase 5.
49
50 * MIDI driver:
51 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
52 the ALSA sequencer client name
53
54 * LSCP server:
55 - added support for sending MIDI CC messages via LSCP command
56 "SEND CHANNEL MIDI_DATA CC <sampler-chan> <ctrl> <val>"
57
58 * Bug fixes:
59 - Fixed crash which may occur when MIDI key + transpose is out of range
60
61 Version 1.0.0 (31 July 2009)
62
63 * packaging changes:
64 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
65 causing e.g. the libgig test to fail when
66 "./configure --disable-jack-driver" was used
67 (patch by Alexis Ballier)
68 - fixed compilation with gcc 4.3
69 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
70 - fixed configure so it detects x86_64 (#107)
71 - fixes for building with newer MinGW versions
72 - fix for building with bison 2.4 (#111)
73 - fixed building with libgig installed in a non-standard directory
74 - minor fix in configure for mmsystem.h detection on MinGW
75 - Windows: look for editor plugins and Fantasia using base
76 directory of liblinuxsampler dll (look in the same directory and one
77 directory above)
78 - configure script fix: removed unconditional use of SSE
79 - fixed building with sqlite installed in a non-standard directory
80 - when cross-compiling, don't try to create instruments.db
81 - fix for new mingw-w64 version, which has usleep
82
83 * general changes:
84 - bugfix: on some POSIX systems instrument editor plugins refused to
85 load as we used a non-portable Linux specific struct field
86 (fixes bug #70, patch by Ronald Baljeu)
87 - fixed endless loop which occured when loading an instrument editor
88 plugin DLL on Windows systems failed
89 - fixed memory leaks that occurred when liblinuxsampler was unloaded
90 - optimized the SynchronizedConfig class so it doesn't wait
91 unnecessarily long after an update
92 - added support for notifying instrument editors on note-on / note-off
93 events (e.g. to highlight the pressed keys on the virtual keyboard
94 of gigedit)
95 - added support for triggering notes by instrument editors (see above)
96 - be verbose on DLL load errors (on Linux)
97 - fixed di-harmonic triangle LFO implementation (this LFO implementation
98 is only used by very few systems, most pick the int math
99 implementation, which is usually faster)
100 - fixes for audio drivers with varying buffer sizes
101 - experimental support for running LinuxSampler as a DSSI, LV2 and
102 VST plugin
103 - notification events for stream/voice count statistics are now sent
104 only when there are actual changes
105 - added memory ordering constraints to improve stability on
106 multi-core and multi-cpu systems
107 - maximum voices and disk streams can now be altered at runtime
108 - fixed CPU feature detection on x86_64 (maybe fixes #108)
109 - automatic stacktrace mechanism is now turned off by default and can
110 be switched on by command line option "--stacktrace" (the automatic
111 stacktrace mechanism seems to be broken on most systems at the moment)
112 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
113 a pointer to the launched InstrumentEditor object
114 - added optional 3rd party user data parameter for following
115 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
116 InstrumentEditor::Launch(),
117 InstrumentManager::LaunchInstrumentEditor()
118 - theoretical fix: made SynchronizedConfig follow C++0x memory
119 model more strictly
120 - fixes for using large audio device buffers
121 - Windows: add the installation directory to the DLL search path
122 when loading an editor plugin (solves problems with VST and
123 gigedit on systems with other GTK versions installed)
124
125 * audio driver:
126 - removed the nonsense audio channel constraint (which was hard coded to
127 max. 100 audio channels) for most audio drivers
128 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
129 opposed to the LSCP specs
130 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
131 reflected the wrong value
132 - fixed a memory management bug in ASIO driver
133 - Makefile fix: JACK_CFLAGS wasn't used
134 - JACK: use jack_client_open instead of the deprecated
135 jack_client_new
136 - added (experimental) CoreAudio driver
137 - applied old fixes to the ASIO driver that were included in the
138 previous binary release but accidentally never committed to CVS
139 (fixes #117)
140 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
141 win64)
142 - VST: added support for sample rate and buffer size changes
143 - VST: close editor (Fantasia) when the VST is removed
144 - VST: avoid opening Fantasia more than once for each VST instance
145 - VST: export main function as "main" on Linux too (fix for
146 energyXT)
147 - VST: changed number of output channels from one stereo to 16
148 stereo
149 - added channel routing, fxsends and midi maps to the settings
150 stored in the plugin state
151 - performance optimization of AudioChannel::MixTo() and
152 AudioChannel::CopyTo() methods using GCC vector exensions
153 (if available)
154 - ASIO fixes: avoid initializing the device twice, avoid throwing
155 exception when getting parameters from a disconnected device
156
157 * MIDI driver:
158 - added JACK MIDI driver
159 - dispatch bank select as ordinary CC as well, the user might seriously
160 want to (mis)use it for some purpose ("fixed" in all current MIDI
161 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
162 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
163 CoreMidi or AU
164 - fixed mingw-w64 compilation error in MME driver
165 - made program change handling in MIDI thread real-time safe by
166 moving the logic to a non-RT thread
167 - fixed minor memory leak in ALSA driver
168
169 * instruments database:
170 - avoid time consuming samples scanning when adding instruments
171 to the instruments database
172 - added support for handling lost files in the instruments database
173 - Implemented option for adding instruments in separate directories
174 in the instruments database
175 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
176 - work-around for missing fnmatch function on Windows to make
177 instrument database compilable
178 - added instrument database support on Windows
179 works with both standalone mode and VST plugin.
180 the instruments DB file is located in
181 %USERPROFILE%\.linuxsampler\instruments.db which allows different
182 databases for each windows user
183 if no DB is present it automatically creates the .linuxsampler subdir
184 and then creates an empty DB
185 - fixed recursive import, which was broken on Windows
186
187 * Gigasampler format engine:
188 - fixed a memory leak that could happen when a channel was deleted
189 while notes were playing
190 - made it possible to load an instrument even if the audio thread
191 isn't running
192 - added partial support for the "Controller Triggered" MIDI rule,
193 enough for piano gigs with pedal noise samples
194 - minor fix: only mark FX sends as being modified if really the
195 respective FX send MIDI controller was used
196 - added support for GM global device volume SysEx message
197 (can be selected at compile time to either apply globally to the
198 whole sampler [default] or only to the sampler channels that are
199 connected to the respective MIDI input port the SysEx message arrived
200 on)
201 - bugfix: notes triggered at position 0 in the audio buffer were
202 sometimes wrongly killed in the same buffer, causing no sound to
203 be played
204 - added support for chromatic / drumkit mode Roland GS Sysex message
205 which is usally used to switch a part between chromatic sounds and
206 drumkit sounds (as opposed to their common default setting of MIDI
207 part 10 being a drumkit part and all other ones chromatic parts), in
208 LS however one can switch between the first 16 MIDI instrument maps
209 defined for the sampler
210 - made it possible to create multiple sample channels even if the
211 audio thread isn't running
212 - fixed crash when removing channel with active voices (#116)
213 - bugfix: on sample reference changes (instrument editor), only
214 un-cache the respective sample if it's really not used by any
215 sampler engine anymore
216 - re-cache samples in case they were changed by an instrument editor,
217 e.g. when a sample was added while playing (#82)
218 - fixed hanging notes which occured when note-off event had the exact
219 same time stamp as the voice's note-on event and occured both in the
220 same audio fragment cycle (fixes bug #112)
221 - added support for the "fine tune" and "pitch bend range"
222 instrument-level gig parameters
223 - fixed minor artifacts in pitch bend handling
224 - added support for GS Reset SysEx message
225 - allow gig files to use unlimited downward pitch shifting
226 - added a limit check for upward pitch shifting
227 - bugfix: sometimes, when playing a note twice fast, the second
228 note was silent
229 - fixed crash happening when a pitch bend event arrived at the
230 same time a new instrument was loading
231
232 * LSCP server:
233 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
234 react on MIDI data arriving on certain sampler channels (so far only
235 Note-On and Note-Off events are sent via this LSCP event)
236 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
237 react on MIDI data arriving on certain MIDI input devices (so far only
238 Note-On and Note-Off events are sent via this LSCP event)
239 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
240 SET DB_INSTRUMENT FILE_PATH
241 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
242 frontends to send MIDI messages to specific sampler channel
243 - added two additional fields to GET FILE INSTRUMENT INFO command -
244 KEY_BINDINGS and KEYSWITCH_BINDINGS
245 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
246 was incorrect
247 - Optimized the retrieval of the MIDI instrument mappings
248 - added new LSCP command "SET VOICES" to globally alter the maximum
249 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
250 be triggered respectively
251 - added new LSCP command "SET STREAMS" to globally alter the maximum
252 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
253 which will be triggered respectively
254 - bugfix: retry if "select" returns EINTR (this fixes a crash when
255 a gigedit file dialog is opened)
256 - close all connections when LSCPServer is deleted
257 - hard close of all sockets on exit
258 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
259 driver
260
261 * Bug fixes:
262 - fixed a crash which occurs when removing a sampler channel waiting
263 to start instrument loading after another channel
264 - fixed a crash which occurs when removing a sampler channel with
265 instrument loading in progress (bug #113)
266 - fixed termination caused by uncaught exception when adding MIDI
267 instrument with PERSISTENT load mode
268 - fixed possible iterator invalidations when resetting the sampler
269 - fixed memory leaks when issuing the following LSCP commands:
270 GET AUDIO_OUTPUT_DRIVER INFO
271 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
272 GET MIDI_INPUT_DRIVER INFO
273 GET MIDI_INPUT_DRIVER_PARAMETER INFO
274 - fixed possible compilation error when sqlite is not present
275 - fixed orphaned pointers when setting maximum voices limit (bug #118)
276 - fixed crash when changing the audio output device of a sampler
277 channel with loaded instrument and start playing notes
278 - fixed endless loop in Engine::SuspendAll() (bug #120)
279 - fixed a low-level atomic load function that was broken on 64-bit
280 PowerPC, which probably could cause crashes on that platform
281 - fixed a memory management error which could cause a crash when a
282 plugin was unloaded
283 - bugfix: two private structs had the same name, which could cause
284 problems if the linker chose the wrong constructor
285 - fixed low-level ConditionServer usage bug that caused lockups on
286 Windows
287
288
289 Version 0.5.1 (6 December 2007)
290
291 * packaging changes:
292 - added autoconf checks for pthread library
293 - added autoconf check for pthread bug found on certain NPTL-enabled
294 glibc versions (see Gentoo bug report #194076)
295 - added autoconf checks for MS Windows
296
297 * general changes:
298 - bugfix: the thread used by an editor plugin didn't die when the
299 editor closed
300 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
301 out all the space. operator--() did not apply size_mask after
302 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
303 order to avoid problems with the _NonVolatileReader functions.
304 - bugfix: Stream.h: added a missing divide by BytesPerSample in
305 GetWriteSpace(). Since this function is currently only used in
306 the stream's qsort() compare function, it didn't trigger any
307 bugs.
308 - Resampler.h, Synthesizer.h: cubic interpolation now works in
309 24bit mode too. Faster method to read 24bit words on little
310 endian machines (x86): replaced 3 byte reads + shifts with a 1
311 unaligned 32bit read and shift
312 - experimental support for MS Windows (MIDI input via MME, AUDIO
313 output via ASIO)
314 - made handling of SIGINT signal (Ctrl-C) a bit more robust
315 - support for monitoring the total number of active disk streams
316 (new LSCP commands: GET TOTAL_STREAM_COUNT,
317 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
318
319 * AUDIO driver:
320 - added Windows ASIO low latency audio driver
321
322 * MIDI driver:
323 - added MME Windows MIDI driver
324
325 * LSCP server:
326 - added support for Windows style path / filenames, however with
327 forward slash path separators instead of backslash
328 (i.e. "C:/foo/bar.gig")
329 - allow naughty liblscp to send non-string device parameters within
330 apostrophes as well
331 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
332 "LIST FILE INSTRUMENTS <file>" and
333 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
334 about an arbitrary instrument file on the system where the sampler is
335 running on
336
337 Version 0.5.0 (15 October 2007)
338
339 * packaging changes:
340 - config.h is not going to be installed along with liblinuxsampler's
341 API header files anymore
342 - only the API relevant header (and source) files will be exported to
343 the Doxygen API documentation (explicitly listed in Doxyfile.in)
344 - added completely new XCode project files for Mac OSX which is now
345 capable to execute our autoconf environment, thus no need anymore
346 to maintain the compile time configuration file (osx/version.h) for
347 OSX manually (patch by Toshi Nagata)
348 - fixed buggy boolean --enable-foo / --disable-foo configure script
349 parameters
350 - global.h now only covers global definitions that are needed for the
351 C++ API header files, all implementation internal global definitions
352 are now in global_private.h
353 - atomic.h is not exposed to the C++ API anymore
354 - no need to include config.h anymore for using LS's API header files
355 - fixed warnings in API doc generation
356
357 * general changes:
358 - replaced the old, confusing MIDI program change mechanism by a
359 flexible MIDI instrument mapper which allows to map arbitrary
360 (MIDI bank, MIDI program) pairs with arbitrary
361 (engine type, instrument file, file index) triplets which will be
362 loaded on the respective channel when such MIDI program change
363 messages arrive, beside that, each entry allows to define a life-time
364 strategy for the instrument, so the user can define whether the
365 instrument should i.e. be permanently loaded (to be able to switch
366 quickly among sounds) or i.e. loaded just on demand when the
367 respective program change arrives (to safe RAM space), as well as a
368 global volume factor for each entry, so the user can adjust the volume
369 dynamic of his mapped instrument collection without having to modify
370 the instrument files, also one can manage arbitrary amount of such
371 MIDI instrument maps and assign each sampler channel individually
372 a certain map, so that i.e. separation of normal instruments and
373 drumkits is possible
374 - new notification events for tracking changes to audio/MIDI devices,
375 MIDI instrument maps, MIDI instruments, FX sends, global volume.
376 - sampler was limited to load max. 200 instruments in the background
377 due to a constant size RingBuffer FIFO which is now replaced by a
378 dynamic (unlimited) size std::list FIFO
379 - added FX sends, these allow to route audio signals to arbitrary audio
380 output channels for being processed by external effect processors
381 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
382 controllers
383 - global (sampler wide) volume can now be controlled at runtime
384 - Implemented new, improved notification system
385 - fixed compilation errors regarding OSX
386 (patch by Toshi Nagata)
387 - implemented instruments database
388 - added support for escape sequences to the instruments database
389 - added highly experimental support for on-the-fly instrument editing
390 within the sampler's process (by using instrument editor plugins),
391 you'll notice the new "Registered instrument editors:" message on
392 startup, added a new LSCP command:
393 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
394 to spawn a matching instrument editor for the instrument on the
395 given sampler channel, the plugin path can be overridden at compile
396 time with ./configure --enable-plugin-dir=/some/dir
397 - added experimental code for synchronizing instrument editors hosted
398 in the sampler's process to safely edit instruments while playing
399 without a crash (hopefully) by either suspending single regions
400 wherever possible or if unavoidable whole engine(s)
401 - fixed several issues in fundamental "Thread" class: set scheduling
402 policy and priority on thread level, set a minimum stack size for
403 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
404 threads simply inherited properties of starting thread instead of
405 setting their own policy and priority
406 - minor fix in our automatic stack trace mechanism on crashes, the
407 main process did not wait for the stack trace process to finish
408 its output
409 - fixed some minor memory leaks
410 - reenabled assembly features support, at the moment only for
411 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
412 - minor assembly fix in x86 features detection (don't use the PIC
413 register, to avoid relocations in the text segment at runtime)
414 - POSIX callback functions of Thread.h are hidden
415
416 * MIDI driver:
417 - dispatch bank select (MSB and LSB) messages
418
419 * audio driver:
420 - the ALSA audio output driver parameters now reflect the correct
421 parameter value ranges for the respective selected sound card
422 (patch by Till Wimmer, a bit fixed and extended)
423
424 * Gigasampler format engine:
425 - if a filter is used and EG2 finishes before EG1, let the voice
426 die when EG2 has finished (this fixes a problem with clicks and
427 voice starvation for some gigs)
428 - playback is no longer disabled during instrument loading
429 - all notes playing on a channel that changes its instrument keep
430 playing with the old instrument until they get a note off
431 command
432 - EG fix: a release value of zero could cause noises or crash
433 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
434 - EG fine tuning: when attack is zero the EG starts at a level
435 above max sustain level, which means that there is a decay phase
436 even if sustain is 100%
437 - more EG fixes: the level could sometimes go below zero and cause
438 noises or crashes
439 - minor fix of EGDecay (patch by Toshi Nagata)
440 - fixed compiler error when --enable-override-filter-type was
441 supplied to the configure script (fixes #46)
442 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
443 instead of a fix value
444 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
445 127 (solo mode) only kill voices if the respective mode really
446 changed
447
448 * LSCP server:
449 - fixed compile time error for old Bison versions
450 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
451 - parser now supports extended ASCII character set
452 (up to ASCII code 255, i.e. includes now umlauts and accents)
453 - filename arguments in LSCP commands now allow to use escape
454 sequences, that is directly literal as one of: \', \", \\, \n, \r,
455 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
456 code value like \xf2) (fixes bug #24)
457 - the following LSCP commands now also support escape sequences for at
458 least one of their text-based parameters (i.e. name, description):
459 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
460 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
461 "SET DB_INSTRUMENT_DIRECTORY NAME",
462 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
463 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
464 "FIND DB_INSTRUMENT_DIRECTORIES"
465 - returns verbose syntax errors (line and column where syntax error
466 occured, the unexpected character and the actually expected, possible
467 character(s), the latter only if less than 5 possibilities)
468 - made sure that LSCP syntax is not affected by gigedit locale
469 settings
470 - bugfix regarding strings parameter lists: all comma separated lists
471 of strings were treated as being one string containing commas
472 (fixes #57)
473
474 * Bug fixes:
475 - fixed crash occurring on certain LSCP scripts (Bug 39)
476 - another thread safety fix for lscp "load engine" and "set
477 channel audio output device"
478 - fixed a crash which occurs when reassigning the same engine
479 on a sampler channel with connected MIDI device
480 - fixed a crash which occurs when changing the number of ports of a MIDI
481 device connected to a sampler channel to number less then or equal
482 to the index of the port to which the sampler channel is connected.
483 - The previous bindings were not been disconnected when altering
484 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
485 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
486 - The active stream/voice count statistic was incorrect.
487 - notification events were not been sent for some sampler
488 channel changes
489 - added default min and max values to restrict the number of allowed
490 audio output channels and MIDI input ports
491 - the connection to the PCM interface is now closed when destroying
492 an audio output device
493 - files with slash in their path or filename could not be loaded
494
495 * test cases:
496 - updated and fixed (haven't been touched in a while)
497
498 Version 0.4.0 (24 November 2006)
499
500 * packaging changes:
501 - changed deprecated copyright attribute to license; added ldconfig
502 to post-(un)install steps; added devel package for liblinuxsampler;
503 to linuxsampler.spec (RPM)
504 - install necessary development header files for allowing 3rd party
505 applications to link against liblinuxsampler
506 - liblinuxsampler's API documentation can be generated with 'make docs'
507 (Doxygen required)
508 - added benchmark to automatically detect the best triangle LFO
509 implementation (currently either an integer math solution or a
510 di-harmonic approximation), automatic detection can be overriden
511 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
512 configure script argument though (mandatory for cross-compilation)
513 - do not automatically pick optimized gcc flags if the user already
514 provided some on his own (as CXXFLAGS)
515 - added compile time option to disable processing of All-Notes-Off MIDI
516 messages
517 - added compile time options to allow disabling the various audio and
518 MIDI drivers
519 - fixed automatic GCC CPU switch detection on PPC
520 (patch by Ebrahim Mayat)
521
522 * Gigasampler format engine:
523 - extensive synthesis optimization
524 (reimplementation of EGs and LFO(s), removed synthesis parameter
525 prerendering and the synthesis parameter matrix in general, splitting
526 each audio fragment into subfragments now where each subfragment uses
527 constant pitch and filter coefficients. The volume coefficient is
528 linearly interpolated inside a subfragment, unless
529 --disable-interpolate-volume is set.)
530 - fine tuning of the EG modulation parameters
531 - improved filter cutoff calculation by adding support for the
532 following gig parameters: Cutoff freq (used when no cutoff
533 controller is defined), Control invert, Minimum cutoff, Velocity
534 curve and Velocity range. The keyboard tracking now scales
535 cutoff frequency instead of resonance.
536 - added support for gig parameter Resonance.
537 - fixed bug in sysex handling (patch by Juan Linietsky)
538 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
539 which can be overridden with --enable-global-attenuation
540 - EG fixes: made the length of "attack hold" stage more
541 accurate. Release stage can now start before attack stage
542 ends. Cancel release didn't work when sustain was zero. Attack
543 time now has a minimal value to prevent clicks.
544 - fixed pitch changes larger than one octave
545 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
546 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
547 all modes can be altered via standard GM messages, that is CC5 for
548 altering portamento time, CC65 for enabling / disabling portamento
549 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
550 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
551 parameter) and crossfade
552 - added support for the "attenuation controller threshold" gig
553 parameter
554 - added smoothing of volume changes caused by control change
555 messages
556 - sample loop parameters are now taken from the DimensionRegion
557 instead of the wave chunk
558 - fixed keyswitching for v3 gigs with a number of keyswitch splits
559 not equal to a power of two
560 - reimplementation of the filter algorithm. The new filter is more
561 accurate and supports all gig filter types, including bandreject
562 and lowpass turbo.
563 - real support for 24 bit samples - samples are not truncated to
564 16 bits anymore
565 - support for aftertouch (channel pressure, not polyphonic
566 aftertouch)
567 - LFO1 behaviour fixed (dampening from max volume instead of
568 amplifying from 0)
569
570 * LSCP server:
571 - fixed application exit on broken pipe error (fixes bug #20)
572 - fixed the notification messages delay due to lack of
573 network activity (fixes bug #26)
574 - fixed parser bug which occured on space(s) within device parameters
575 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
576
577 * audio driver:
578 - added aRts audio output driver (by no means RT safe)
579
580 * MIDI driver:
581 - fixed legacy sysex code which caused dispatching of MIDI SysEx
582 messages several times instead of once
583 - API extension for MIDI drivers which already supply exact time stamps
584 for events (i.e. for offline rendering based MIDI drivers)
585 - added checks for bad MIDI data
586
587 * linuxsampler application:
588 - show available sampler engine types on startup
589
590 * general changes:
591 - support for muting sampler channels and solo mode of the same, two new
592 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
593 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
594 introduced for this, the behavior is the same like on a mixer console
595 (patch by Grigor Iliev, a bit adjusted). Also added configure option
596 --enable-process-muted-channels which can be used to enable the
597 processing of muted channels.
598 - support for sostenuto pedal
599 - support for monitoring the total number of active voices
600 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
601 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
602 - fixed some memory management errors
603 - fixed some concurrency problems that could lead to crashes when
604 LSCP commands were executed
605 - fixed crash when instrument loading failed previously on the same
606 sampler channel (fixes bug #36)
607
608 Version 0.3.3 (15 July 2005)
609
610 * packaging changes:
611 - fixed compilation with gcc 4.0
612
613 * Gigasampler format engine:
614 - LFO preprocessing was performed even though the respective LFO was
615 disabled by the instrument patch (minor efficiency fix)
616 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
617 for volume ramp downs in the same fragment (needed for current voice
618 stealing implementation) then simply inform the user with a warning
619 about possible click sounds and reduce the volume ramp down
620 appropriately instead of cancelling the audio device connection
621
622 Version 0.3.2 (24 June 2005)
623
624 * packaging changes:
625 - updated autotools build files to compile on OS X
626 (conditional compilation of CoreMIDI and MidiShare drivers)
627 - hand-crafted assembly optimization code can be disabled with
628 './configure --disable-asm' (definitely not recommended)
629 - fixed 'make dist' rule to include all necessary files
630 - require automake (>= 1.5) for 'make -f Makefile.cvs'
631 (due to 'dist-bzip2' automake option)
632
633 * Gigasampler format engine:
634 - support for the gig parameters for "release velocity response" curves
635 - fine tuning of the EGADSR envelope
636 - volume of release triggered samples now depends on note-on velocity,
637 note length and gig parameter "release trigger decay" instead of
638 note-off velocity.
639 - revised voice stealing
640 (fixes crash and endless loop caused by voice stealing)
641 - don't reset scale tuning on instrument or audio output device change
642 - handle key group conflicts right at the beginning of each fragment
643 instead of when the respective voice is actually launched
644 (fixes undefined behavior if stolen voices belonged to a key group -
645 this case was followed by a "killed voice survived" error message)
646 - fixed minor issue with null/silence samples
647 (those stole voices even though they don't need a voice at all which
648 resulted in "voice stealing didn't work out" messages)
649 - don't reset volume, pan, pitch and MIDI controller values on
650 instrument or audio output device change
651
652 * LSCP server:
653 - fixed some crashes (patch by Grigor Iliev, fixes #19)
654 - fixed LSCP event "CHANNEL_INFO" notification
655 (e.g. did not notify on volume changes or MIDI program change events)
656
657 * linuxsampler application:
658 - added command line parameters --lscp-addr and --lscp-port to override
659 default IP address and port of LSCP server
660
661 Version 0.3.1 (24 May 2005)
662
663 * initial release
