Tue Oct 5 10:35:13 2010 UTC (9 years, 2 months ago) by schoenebeck
File size: 37404 byte(s)
* raised limit of program change queue from 100 to 512
  (as suggested by Alex Stone)
* removed limit of maximum amount of MIDI ports per MIDI device, since
  there is no reason for this limit
* minor syntax simplification regarding 2 new LSCP commands: changed
  "SET FX_SEND SEND_EFFECT"" to "SET FX_SEND EFFECT" and changed
  "REMOVE FX_SEND SEND_EFFECT"" to "REMOVE FX_SEND EFFECT", also changed
  the respective category field of command "GET FX_SEND INFO" from
  "SEND_EFFECT" to "EFFECT"
* updated LSCP specification document
* bumped version to 1.0.0.cvs10

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 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
16 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
17 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
18 note (in this implementation of the sampler its simply hard routed to
19 the 1st effect send of the sampler channel, no matter what the actual
20 effect type is)
21 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
22 note (in this implementation of the sampler its simply hard routed to
23 the 2nd effect send of the sampler channel, no matter what the actual
24 effect type is)
25 - implemented support for internal LADSPA effects
26 - raised limit of program change queue from 100 to 512
27 (as suggested by Alex Stone)
28
29 * Gigasampler format engine:
30 - implemented the "round robin keyboard" dimension
31 - fixed round robin and random dimensions for cases when number of
32 dimension zones is not a power of two
33 - made round robin use a counter for each region instead of each
34 key
35
36 * SFZ format engine:
37 - Initial implementation (not usable yet)
38 - added support for v2 multiple stage envelope generators
39 - added a fine-tuned v1 envelope generator instead of using the
40 one from the gig engine
41 - fixed memory leak and memory handling errors
42 - added support for trigger=first, trigger=legato and sw_previous
43 - allow non-numerical key values ("C#4" for example)
44 - "key" opcode now sets pitch_keycenter too
45 - fixed error when unloading instrument with same sample used by
46 multiple regions
47 - added some opcode aliases, like loopmode for loop_mode, to be
48 more compatible
49 - added support for trigger=release and rt_decay
50 - added support for off_mode=normal

72 - RT-safeness: avoid malloc in audio thread
73 - fixed a bug that could cause voice stealing to fail
74
75 * Host plugins:
76 - AU bugfix: failed to destroy its audio/MIDI devices
77 - Listen to all interfaces on Mac OS X (INADDR_ANY)
78 - VST bugfix: If the host called resume() before and after
79 changing sample rate or block size, the number of channels was
80 incorrectly set to two. This caused silence in Cubase 5.
81
82 * MIDI driver:
83 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
84 the ALSA sequencer client name
85 - removed limit of maximum amount of MIDI ports per MIDI device, since

129
130 Version 1.0.0 (31 July 2009)
131
132 * packaging changes:
133 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
134 causing e.g. the libgig test to fail when
135 "./configure --disable-jack-driver" was used
136 (patch by Alexis Ballier)
137 - fixed compilation with gcc 4.3
138 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
139 - fixed configure so it detects x86_64 (#107)
140 - fixes for building with newer MinGW versions
141 - fix for building with bison 2.4 (#111)
142 - fixed building with libgig installed in a non-standard directory
143 - minor fix in configure for mmsystem.h detection on MinGW
144 - Windows: look for editor plugins and Fantasia using base
145 directory of liblinuxsampler dll (look in the same directory and one
146 directory above)
147 - configure script fix: removed unconditional use of SSE
148 - fixed building with sqlite installed in a non-standard directory
149 - when cross-compiling, don't try to create instruments.db
150 - fix for new mingw-w64 version, which has usleep
151
152 * general changes:
153 - bugfix: on some POSIX systems instrument editor plugins refused to
154 load as we used a non-portable Linux specific struct field
155 (fixes bug #70, patch by Ronald Baljeu)
156 - fixed endless loop which occured when loading an instrument editor
157 plugin DLL on Windows systems failed
158 - fixed memory leaks that occurred when liblinuxsampler was unloaded
159 - optimized the SynchronizedConfig class so it doesn't wait
160 unnecessarily long after an update
161 - added support for notifying instrument editors on note-on / note-off
162 events (e.g. to highlight the pressed keys on the virtual keyboard
163 of gigedit)
164 - added support for triggering notes by instrument editors (see above)
165 - be verbose on DLL load errors (on Linux)
166 - fixed di-harmonic triangle LFO implementation (this LFO implementation
167 is only used by very few systems, most pick the int math
168 implementation, which is usually faster)
169 - fixes for audio drivers with varying buffer sizes
170 - experimental support for running LinuxSampler as a DSSI, LV2 and
171 VST plugin
172 - notification events for stream/voice count statistics are now sent
173 only when there are actual changes
174 - added memory ordering constraints to improve stability on
175 multi-core and multi-cpu systems
176 - maximum voices and disk streams can now be altered at runtime
177 - fixed CPU feature detection on x86_64 (maybe fixes #108)
178 - automatic stacktrace mechanism is now turned off by default and can
179 be switched on by command line option "--stacktrace" (the automatic
180 stacktrace mechanism seems to be broken on most systems at the moment)
181 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
182 a pointer to the launched InstrumentEditor object
183 - added optional 3rd party user data parameter for following
184 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
185 InstrumentEditor::Launch(),
186 InstrumentManager::LaunchInstrumentEditor()
187 - theoretical fix: made SynchronizedConfig follow C++0x memory
188 model more strictly
189 - fixes for using large audio device buffers
190 - Windows: add the installation directory to the DLL search path
191 when loading an editor plugin (solves problems with VST and
192 gigedit on systems with other GTK versions installed)
193
194 * audio driver:
195 - removed the nonsense audio channel constraint (which was hard coded to
196 max. 100 audio channels) for most audio drivers
197 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
198 opposed to the LSCP specs
199 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
200 reflected the wrong value
201 - fixed a memory management bug in ASIO driver
202 - Makefile fix: JACK_CFLAGS wasn't used
203 - JACK: use jack_client_open instead of the deprecated
204 jack_client_new
205 - added (experimental) CoreAudio driver
206 - applied old fixes to the ASIO driver that were included in the
207 previous binary release but accidentally never committed to CVS
208 (fixes #117)
209 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
210 win64)
211 - VST: added support for sample rate and buffer size changes
212 - VST: close editor (Fantasia) when the VST is removed
213 - VST: avoid opening Fantasia more than once for each VST instance
214 - VST: export main function as "main" on Linux too (fix for
215 energyXT)
216 - VST: changed number of output channels from one stereo to 16
217 stereo
218 - added channel routing, fxsends and midi maps to the settings
219 stored in the plugin state
220 - performance optimization of AudioChannel::MixTo() and
221 AudioChannel::CopyTo() methods using GCC vector exensions
222 (if available)
223 - ASIO fixes: avoid initializing the device twice, avoid throwing
224 exception when getting parameters from a disconnected device
225
226 * MIDI driver:
227 - added JACK MIDI driver
228 - dispatch bank select as ordinary CC as well, the user might seriously
229 want to (mis)use it for some purpose ("fixed" in all current MIDI
230 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
231 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
232 CoreMidi or AU
233 - fixed mingw-w64 compilation error in MME driver
234 - made program change handling in MIDI thread real-time safe by
235 moving the logic to a non-RT thread
236 - fixed minor memory leak in ALSA driver
237
238 * instruments database:
239 - avoid time consuming samples scanning when adding instruments
240 to the instruments database
241 - added support for handling lost files in the instruments database
242 - Implemented option for adding instruments in separate directories
243 in the instruments database
244 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
245 - work-around for missing fnmatch function on Windows to make
246 instrument database compilable
247 - added instrument database support on Windows
248 works with both standalone mode and VST plugin.
249 the instruments DB file is located in
250 %USERPROFILE%\.linuxsampler\instruments.db which allows different
251 databases for each windows user
252 if no DB is present it automatically creates the .linuxsampler subdir
253 and then creates an empty DB
254 - fixed recursive import, which was broken on Windows
255
256 * Gigasampler format engine:
257 - fixed a memory leak that could happen when a channel was deleted
258 while notes were playing
259 - made it possible to load an instrument even if the audio thread
260 isn't running
261 - added partial support for the "Controller Triggered" MIDI rule,
262 enough for piano gigs with pedal noise samples
263 - minor fix: only mark FX sends as being modified if really the
264 respective FX send MIDI controller was used
265 - added support for GM global device volume SysEx message
266 (can be selected at compile time to either apply globally to the
267 whole sampler [default] or only to the sampler channels that are
268 connected to the respective MIDI input port the SysEx message arrived
269 on)
270 - bugfix: notes triggered at position 0 in the audio buffer were
271 sometimes wrongly killed in the same buffer, causing no sound to
272 be played
273 - added support for chromatic / drumkit mode Roland GS Sysex message
274 which is usally used to switch a part between chromatic sounds and
275 drumkit sounds (as opposed to their common default setting of MIDI
276 part 10 being a drumkit part and all other ones chromatic parts), in
277 LS however one can switch between the first 16 MIDI instrument maps
278 defined for the sampler
279 - made it possible to create multiple sample channels even if the
280 audio thread isn't running
281 - fixed crash when removing channel with active voices (#116)
282 - bugfix: on sample reference changes (instrument editor), only
283 un-cache the respective sample if it's really not used by any
284 sampler engine anymore
285 - re-cache samples in case they were changed by an instrument editor,
286 e.g. when a sample was added while playing (#82)
287 - fixed hanging notes which occured when note-off event had the exact
288 same time stamp as the voice's note-on event and occured both in the
289 same audio fragment cycle (fixes bug #112)
290 - added support for the "fine tune" and "pitch bend range"
291 instrument-level gig parameters
292 - fixed minor artifacts in pitch bend handling
293 - added support for GS Reset SysEx message
294 - allow gig files to use unlimited downward pitch shifting
295 - added a limit check for upward pitch shifting
296 - bugfix: sometimes, when playing a note twice fast, the second
297 note was silent
298 - fixed crash happening when a pitch bend event arrived at the
299 same time a new instrument was loading
300
301 * LSCP server:
302 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
303 react on MIDI data arriving on certain sampler channels (so far only
304 Note-On and Note-Off events are sent via this LSCP event)
305 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
306 react on MIDI data arriving on certain MIDI input devices (so far only
307 Note-On and Note-Off events are sent via this LSCP event)
308 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
309 SET DB_INSTRUMENT FILE_PATH
310 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
311 frontends to send MIDI messages to specific sampler channel
312 - added two additional fields to GET FILE INSTRUMENT INFO command -
313 KEY_BINDINGS and KEYSWITCH_BINDINGS
314 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
315 was incorrect
316 - Optimized the retrieval of the MIDI instrument mappings
317 - added new LSCP command "SET VOICES" to globally alter the maximum
318 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
319 be triggered respectively
320 - added new LSCP command "SET STREAMS" to globally alter the maximum
321 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
322 which will be triggered respectively
323 - bugfix: retry if "select" returns EINTR (this fixes a crash when
324 a gigedit file dialog is opened)
325 - close all connections when LSCPServer is deleted
326 - hard close of all sockets on exit
327 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
328 driver
329
330 * Bug fixes:
331 - fixed a crash which occurs when removing a sampler channel waiting
332 to start instrument loading after another channel
333 - fixed a crash which occurs when removing a sampler channel with
334 instrument loading in progress (bug #113)
335 - fixed termination caused by uncaught exception when adding MIDI
336 instrument with PERSISTENT load mode
337 - fixed possible iterator invalidations when resetting the sampler
338 - fixed memory leaks when issuing the following LSCP commands:
339 GET AUDIO_OUTPUT_DRIVER INFO
340 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
341 GET MIDI_INPUT_DRIVER INFO
342 GET MIDI_INPUT_DRIVER_PARAMETER INFO
343 - fixed possible compilation error when sqlite is not present
344 - fixed orphaned pointers when setting maximum voices limit (bug #118)
345 - fixed crash when changing the audio output device of a sampler
346 channel with loaded instrument and start playing notes
347 - fixed endless loop in Engine::SuspendAll() (bug #120)
348 - fixed a low-level atomic load function that was broken on 64-bit
349 PowerPC, which probably could cause crashes on that platform
350 - fixed a memory management error which could cause a crash when a
351 plugin was unloaded
352 - bugfix: two private structs had the same name, which could cause
353 problems if the linker chose the wrong constructor
354 - fixed low-level ConditionServer usage bug that caused lockups on
355 Windows
356
357
358 Version 0.5.1 (6 December 2007)
359
360 * packaging changes:
361 - added autoconf checks for pthread library
362 - added autoconf check for pthread bug found on certain NPTL-enabled
363 glibc versions (see Gentoo bug report #194076)
364 - added autoconf checks for MS Windows
365
366 * general changes:
367 - bugfix: the thread used by an editor plugin didn't die when the
368 editor closed
369 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
370 out all the space. operator--() did not apply size_mask after
371 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
372 order to avoid problems with the _NonVolatileReader functions.
373 - bugfix: Stream.h: added a missing divide by BytesPerSample in
374 GetWriteSpace(). Since this function is currently only used in
375 the stream's qsort() compare function, it didn't trigger any
376 bugs.
377 - Resampler.h, Synthesizer.h: cubic interpolation now works in
378 24bit mode too. Faster method to read 24bit words on little
379 endian machines (x86): replaced 3 byte reads + shifts with a 1
380 unaligned 32bit read and shift
381 - experimental support for MS Windows (MIDI input via MME, AUDIO
382 output via ASIO)
383 - made handling of SIGINT signal (Ctrl-C) a bit more robust
384 - support for monitoring the total number of active disk streams
385 (new LSCP commands: GET TOTAL_STREAM_COUNT,
386 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
387
388 * AUDIO driver:
389 - added Windows ASIO low latency audio driver
390
391 * MIDI driver:
392 - added MME Windows MIDI driver
393
394 * LSCP server:
395 - added support for Windows style path / filenames, however with
396 forward slash path separators instead of backslash
397 (i.e. "C:/foo/bar.gig")
398 - allow naughty liblscp to send non-string device parameters within
399 apostrophes as well
400 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
401 "LIST FILE INSTRUMENTS <file>" and
402 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
403 about an arbitrary instrument file on the system where the sampler is
404 running on
405
406 Version 0.5.0 (15 October 2007)
407
408 * packaging changes:
409 - config.h is not going to be installed along with liblinuxsampler's
410 API header files anymore
411 - only the API relevant header (and source) files will be exported to
412 the Doxygen API documentation (explicitly listed in Doxyfile.in)
413 - added completely new XCode project files for Mac OSX which is now
414 capable to execute our autoconf environment, thus no need anymore
415 to maintain the compile time configuration file (osx/version.h) for
416 OSX manually (patch by Toshi Nagata)
417 - fixed buggy boolean --enable-foo / --disable-foo configure script
418 parameters
419 - global.h now only covers global definitions that are needed for the
420 C++ API header files, all implementation internal global definitions
421 are now in global_private.h
422 - atomic.h is not exposed to the C++ API anymore
423 - no need to include config.h anymore for using LS's API header files
424 - fixed warnings in API doc generation
425
426 * general changes:
427 - replaced the old, confusing MIDI program change mechanism by a
428 flexible MIDI instrument mapper which allows to map arbitrary
429 (MIDI bank, MIDI program) pairs with arbitrary
430 (engine type, instrument file, file index) triplets which will be
431 loaded on the respective channel when such MIDI program change
432 messages arrive, beside that, each entry allows to define a life-time
433 strategy for the instrument, so the user can define whether the
434 instrument should i.e. be permanently loaded (to be able to switch
435 quickly among sounds) or i.e. loaded just on demand when the
436 respective program change arrives (to safe RAM space), as well as a
437 global volume factor for each entry, so the user can adjust the volume
438 dynamic of his mapped instrument collection without having to modify
439 the instrument files, also one can manage arbitrary amount of such
440 MIDI instrument maps and assign each sampler channel individually
441 a certain map, so that i.e. separation of normal instruments and
442 drumkits is possible
443 - new notification events for tracking changes to audio/MIDI devices,
444 MIDI instrument maps, MIDI instruments, FX sends, global volume.
445 - sampler was limited to load max. 200 instruments in the background
446 due to a constant size RingBuffer FIFO which is now replaced by a
447 dynamic (unlimited) size std::list FIFO
448 - added FX sends, these allow to route audio signals to arbitrary audio
449 output channels for being processed by external effect processors
450 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
451 controllers
452 - global (sampler wide) volume can now be controlled at runtime
453 - Implemented new, improved notification system
454 - fixed compilation errors regarding OSX
455 (patch by Toshi Nagata)
456 - implemented instruments database
457 - added support for escape sequences to the instruments database
458 - added highly experimental support for on-the-fly instrument editing
459 within the sampler's process (by using instrument editor plugins),
460 you'll notice the new "Registered instrument editors:" message on
461 startup, added a new LSCP command:
462 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
463 to spawn a matching instrument editor for the instrument on the
464 given sampler channel, the plugin path can be overridden at compile
465 time with ./configure --enable-plugin-dir=/some/dir
466 - added experimental code for synchronizing instrument editors hosted
467 in the sampler's process to safely edit instruments while playing
468 without a crash (hopefully) by either suspending single regions
469 wherever possible or if unavoidable whole engine(s)
470 - fixed several issues in fundamental "Thread" class: set scheduling
471 policy and priority on thread level, set a minimum stack size for
472 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
473 threads simply inherited properties of starting thread instead of
474 setting their own policy and priority
475 - minor fix in our automatic stack trace mechanism on crashes, the
476 main process did not wait for the stack trace process to finish
477 its output
478 - fixed some minor memory leaks
479 - reenabled assembly features support, at the moment only for
480 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
481 - minor assembly fix in x86 features detection (don't use the PIC
482 register, to avoid relocations in the text segment at runtime)
483 - POSIX callback functions of Thread.h are hidden
484
485 * MIDI driver:
486 - dispatch bank select (MSB and LSB) messages
487
488 * audio driver:
489 - the ALSA audio output driver parameters now reflect the correct
490 parameter value ranges for the respective selected sound card
491 (patch by Till Wimmer, a bit fixed and extended)
492
493 * Gigasampler format engine:
494 - if a filter is used and EG2 finishes before EG1, let the voice
495 die when EG2 has finished (this fixes a problem with clicks and
496 voice starvation for some gigs)
497 - playback is no longer disabled during instrument loading
498 - all notes playing on a channel that changes its instrument keep
499 playing with the old instrument until they get a note off
500 command
501 - EG fix: a release value of zero could cause noises or crash
502 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
503 - EG fine tuning: when attack is zero the EG starts at a level
504 above max sustain level, which means that there is a decay phase
505 even if sustain is 100%
506 - more EG fixes: the level could sometimes go below zero and cause
507 noises or crashes
508 - minor fix of EGDecay (patch by Toshi Nagata)
509 - fixed compiler error when --enable-override-filter-type was
510 supplied to the configure script (fixes #46)
511 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
512 instead of a fix value
513 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
514 127 (solo mode) only kill voices if the respective mode really
515 changed
516
517 * LSCP server:
518 - fixed compile time error for old Bison versions
519 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
520 - parser now supports extended ASCII character set
521 (up to ASCII code 255, i.e. includes now umlauts and accents)
522 - filename arguments in LSCP commands now allow to use escape
523 sequences, that is directly literal as one of: \', \", \\, \n, \r,
524 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
525 code value like \xf2) (fixes bug #24)
526 - the following LSCP commands now also support escape sequences for at
527 least one of their text-based parameters (i.e. name, description):
528 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
529 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
530 "SET DB_INSTRUMENT_DIRECTORY NAME",
531 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
532 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
533 "FIND DB_INSTRUMENT_DIRECTORIES"
534 - returns verbose syntax errors (line and column where syntax error
535 occured, the unexpected character and the actually expected, possible
536 character(s), the latter only if less than 5 possibilities)
537 - made sure that LSCP syntax is not affected by gigedit locale
538 settings
539 - bugfix regarding strings parameter lists: all comma separated lists
540 of strings were treated as being one string containing commas
541 (fixes #57)
542
543 * Bug fixes:
544 - fixed crash occurring on certain LSCP scripts (Bug 39)
545 - another thread safety fix for lscp "load engine" and "set
546 channel audio output device"
547 - fixed a crash which occurs when reassigning the same engine
548 on a sampler channel with connected MIDI device
549 - fixed a crash which occurs when changing the number of ports of a MIDI
550 device connected to a sampler channel to number less then or equal
551 to the index of the port to which the sampler channel is connected.
552 - The previous bindings were not been disconnected when altering
553 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
554 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
555 - The active stream/voice count statistic was incorrect.
556 - notification events were not been sent for some sampler
557 channel changes
558 - added default min and max values to restrict the number of allowed
559 audio output channels and MIDI input ports
560 - the connection to the PCM interface is now closed when destroying
561 an audio output device
562 - files with slash in their path or filename could not be loaded
563
564 * test cases:
565 - updated and fixed (haven't been touched in a while)
566
567 Version 0.4.0 (24 November 2006)
568
569 * packaging changes:
570 - changed deprecated copyright attribute to license; added ldconfig
571 to post-(un)install steps; added devel package for liblinuxsampler;
572 to linuxsampler.spec (RPM)
573 - install necessary development header files for allowing 3rd party
574 applications to link against liblinuxsampler
575 - liblinuxsampler's API documentation can be generated with 'make docs'
576 (Doxygen required)
577 - added benchmark to automatically detect the best triangle LFO
578 implementation (currently either an integer math solution or a
579 di-harmonic approximation), automatic detection can be overriden
580 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
581 configure script argument though (mandatory for cross-compilation)
582 - do not automatically pick optimized gcc flags if the user already
583 provided some on his own (as CXXFLAGS)
584 - added compile time option to disable processing of All-Notes-Off MIDI
585 messages
586 - added compile time options to allow disabling the various audio and
587 MIDI drivers
588 - fixed automatic GCC CPU switch detection on PPC
589 (patch by Ebrahim Mayat)
590
591 * Gigasampler format engine:
592 - extensive synthesis optimization
593 (reimplementation of EGs and LFO(s), removed synthesis parameter
594 prerendering and the synthesis parameter matrix in general, splitting
595 each audio fragment into subfragments now where each subfragment uses
596 constant pitch and filter coefficients. The volume coefficient is
597 linearly interpolated inside a subfragment, unless
598 --disable-interpolate-volume is set.)
599 - fine tuning of the EG modulation parameters
600 - improved filter cutoff calculation by adding support for the
601 following gig parameters: Cutoff freq (used when no cutoff
602 controller is defined), Control invert, Minimum cutoff, Velocity
603 curve and Velocity range. The keyboard tracking now scales
604 cutoff frequency instead of resonance.
605 - added support for gig parameter Resonance.
606 - fixed bug in sysex handling (patch by Juan Linietsky)
607 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
608 which can be overridden with --enable-global-attenuation
609 - EG fixes: made the length of "attack hold" stage more
610 accurate. Release stage can now start before attack stage
611 ends. Cancel release didn't work when sustain was zero. Attack
612 time now has a minimal value to prevent clicks.
613 - fixed pitch changes larger than one octave
614 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
615 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
616 all modes can be altered via standard GM messages, that is CC5 for
617 altering portamento time, CC65 for enabling / disabling portamento
618 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
619 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
620 parameter) and crossfade
621 - added support for the "attenuation controller threshold" gig
622 parameter
623 - added smoothing of volume changes caused by control change
624 messages
625 - sample loop parameters are now taken from the DimensionRegion
626 instead of the wave chunk
627 - fixed keyswitching for v3 gigs with a number of keyswitch splits
628 not equal to a power of two
629 - reimplementation of the filter algorithm. The new filter is more
630 accurate and supports all gig filter types, including bandreject
631 and lowpass turbo.
632 - real support for 24 bit samples - samples are not truncated to
633 16 bits anymore
634 - support for aftertouch (channel pressure, not polyphonic
635 aftertouch)
636 - LFO1 behaviour fixed (dampening from max volume instead of
637 amplifying from 0)
638
639 * LSCP server:
640 - fixed application exit on broken pipe error (fixes bug #20)
641 - fixed the notification messages delay due to lack of
642 network activity (fixes bug #26)
643 - fixed parser bug which occured on space(s) within device parameters
644 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
645
646 * audio driver:
647 - added aRts audio output driver (by no means RT safe)
648
649 * MIDI driver:
650 - fixed legacy sysex code which caused dispatching of MIDI SysEx
651 messages several times instead of once
652 - API extension for MIDI drivers which already supply exact time stamps
653 for events (i.e. for offline rendering based MIDI drivers)
654 - added checks for bad MIDI data
655
656 * linuxsampler application:
657 - show available sampler engine types on startup
658
659 * general changes:
660 - support for muting sampler channels and solo mode of the same, two new
661 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
662 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
663 introduced for this, the behavior is the same like on a mixer console
664 (patch by Grigor Iliev, a bit adjusted). Also added configure option
665 --enable-process-muted-channels which can be used to enable the
666 processing of muted channels.
667 - support for sostenuto pedal
668 - support for monitoring the total number of active voices
669 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
670 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
671 - fixed some memory management errors
672 - fixed some concurrency problems that could lead to crashes when
673 LSCP commands were executed
674 - fixed crash when instrument loading failed previously on the same
675 sampler channel (fixes bug #36)
676
677 Version 0.3.3 (15 July 2005)
678
679 * packaging changes:
680 - fixed compilation with gcc 4.0
681
682 * Gigasampler format engine:
683 - LFO preprocessing was performed even though the respective LFO was
684 disabled by the instrument patch (minor efficiency fix)
685 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
686 for volume ramp downs in the same fragment (needed for current voice
687 stealing implementation) then simply inform the user with a warning
688 about possible click sounds and reduce the volume ramp down
689 appropriately instead of cancelling the audio device connection
690
691 Version 0.3.2 (24 June 2005)
692
693 * packaging changes:
694 - updated autotools build files to compile on OS X
695 (conditional compilation of CoreMIDI and MidiShare drivers)
696 - hand-crafted assembly optimization code can be disabled with
697 './configure --disable-asm' (definitely not recommended)
698 - fixed 'make dist' rule to include all necessary files
699 - require automake (>= 1.5) for 'make -f Makefile.cvs'
700 (due to 'dist-bzip2' automake option)
701
702 * Gigasampler format engine:
703 - support for the gig parameters for "release velocity response" curves
704 - fine tuning of the EGADSR envelope
705 - volume of release triggered samples now depends on note-on velocity,
706 note length and gig parameter "release trigger decay" instead of
707 note-off velocity.
708 - revised voice stealing
709 (fixes crash and endless loop caused by voice stealing)
710 - don't reset scale tuning on instrument or audio output device change
711 - handle key group conflicts right at the beginning of each fragment
712 instead of when the respective voice is actually launched
713 (fixes undefined behavior if stolen voices belonged to a key group -
714 this case was followed by a "killed voice survived" error message)
715 - fixed minor issue with null/silence samples
716 (those stole voices even though they don't need a voice at all which
717 resulted in "voice stealing didn't work out" messages)
718 - don't reset volume, pan, pitch and MIDI controller values on
719 instrument or audio output device change
720
721 * LSCP server:
722 - fixed some crashes (patch by Grigor Iliev, fixes #19)
723 - fixed LSCP event "CHANNEL_INFO" notification
724 (e.g. did not notify on volume changes or MIDI program change events)
725
726 * linuxsampler application:
727 - added command line parameters --lscp-addr and --lscp-port to override
728 default IP address and port of LSCP server
729
730 Version 0.3.1 (24 May 2005)
731
732 * initial release
