File size: 37211 byte(s)
* minor fixes regarding new LSCP effect commands
* updated LSCP specification document regarding new effect commands
* bumped version to 1.0.0.cvs9

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
27 * Gigasampler format engine:
28 - implemented the "round robin keyboard" dimension
29 - fixed round robin and random dimensions for cases when number of
30 dimension zones is not a power of two
31 - made round robin use a counter for each region instead of each
32 key
33
34 * SFZ format engine:
35 - Initial implementation (not usable yet)
36 - added support for v2 multiple stage envelope generators
37 - added a fine-tuned v1 envelope generator instead of using the
38 one from the gig engine
39 - fixed memory leak and memory handling errors
40 - added support for trigger=first, trigger=legato and sw_previous
41 - allow non-numerical key values ("C#4" for example)
42 - "key" opcode now sets pitch_keycenter too
43 - fixed error when unloading instrument with same sample used by
44 multiple regions
45 - added some opcode aliases, like loopmode for loop_mode, to be
46 more compatible
47 - added support for trigger=release and rt_decay
48 - added support for off_mode=normal
49 - added support for random, seq_position, seq_length and volume
50 - added v1 LFO opcodes to parser (no support in engine yet)
51 - added support for amp_veltrack and amp_velcurve_N
52 - fine-tuned the default velocity curve
53 - added support for transpose
54 - fixed crash when using sw_down/up
55 - improved logic for sw_lokey/hikey/up/down/last
56 - added more v1 aliases to parser
57 - reduced memory usage for sfz data
58 - RT-safeness: avoid malloc in audio thread
59 - fixed a bug that could cause voice stealing to fail
60 - optimized sample lookup
61 - improved support for exclusive groups (group, off_by and
62 off_mode)
63 - added support for controller triggered regions (on_locc/on_hicc)
64 - added support for loop_mode=one_shot
65 - fixed playback of 16 bit wav files on big endian CPUs
66 - added support for Ogg Vorbis sample files
67
68 * SoundFont format engine:
69 - Initial implementation (not usable yet)
70 - RT-safeness: avoid malloc in audio thread
71 - fixed a bug that could cause voice stealing to fail
72
73 * Host plugins:
74 - AU bugfix: failed to destroy its audio/MIDI devices
75 - Listen to all interfaces on Mac OS X (INADDR_ANY)
76 - VST bugfix: If the host called resume() before and after
77 changing sample rate or block size, the number of channels was
78 incorrectly set to two. This caused silence in Cubase 5.
79
80 * MIDI driver:
81 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
82 the ALSA sequencer client name
83

126
127 Version 1.0.0 (31 July 2009)
128
129 * packaging changes:
130 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
131 causing e.g. the libgig test to fail when
132 "./configure --disable-jack-driver" was used
133 (patch by Alexis Ballier)
134 - fixed compilation with gcc 4.3
135 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
136 - fixed configure so it detects x86_64 (#107)
137 - fixes for building with newer MinGW versions
138 - fix for building with bison 2.4 (#111)
139 - fixed building with libgig installed in a non-standard directory
140 - minor fix in configure for mmsystem.h detection on MinGW
141 - Windows: look for editor plugins and Fantasia using base
142 directory of liblinuxsampler dll (look in the same directory and one
143 directory above)
144 - configure script fix: removed unconditional use of SSE
145 - fixed building with sqlite installed in a non-standard directory
146 - when cross-compiling, don't try to create instruments.db
147 - fix for new mingw-w64 version, which has usleep
148
149 * general changes:
150 - bugfix: on some POSIX systems instrument editor plugins refused to
151 load as we used a non-portable Linux specific struct field
152 (fixes bug #70, patch by Ronald Baljeu)
153 - fixed endless loop which occured when loading an instrument editor
154 plugin DLL on Windows systems failed
155 - fixed memory leaks that occurred when liblinuxsampler was unloaded
156 - optimized the SynchronizedConfig class so it doesn't wait
157 unnecessarily long after an update
158 - added support for notifying instrument editors on note-on / note-off
159 events (e.g. to highlight the pressed keys on the virtual keyboard
160 of gigedit)
161 - added support for triggering notes by instrument editors (see above)
162 - be verbose on DLL load errors (on Linux)
163 - fixed di-harmonic triangle LFO implementation (this LFO implementation
164 is only used by very few systems, most pick the int math
165 implementation, which is usually faster)
166 - fixes for audio drivers with varying buffer sizes
167 - experimental support for running LinuxSampler as a DSSI, LV2 and
168 VST plugin
169 - notification events for stream/voice count statistics are now sent
170 only when there are actual changes
171 - added memory ordering constraints to improve stability on
172 multi-core and multi-cpu systems
173 - maximum voices and disk streams can now be altered at runtime
174 - fixed CPU feature detection on x86_64 (maybe fixes #108)
175 - automatic stacktrace mechanism is now turned off by default and can
176 be switched on by command line option "--stacktrace" (the automatic
177 stacktrace mechanism seems to be broken on most systems at the moment)
178 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
179 a pointer to the launched InstrumentEditor object
180 - added optional 3rd party user data parameter for following
181 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
182 InstrumentEditor::Launch(),
183 InstrumentManager::LaunchInstrumentEditor()
184 - theoretical fix: made SynchronizedConfig follow C++0x memory
185 model more strictly
186 - fixes for using large audio device buffers
187 - Windows: add the installation directory to the DLL search path
188 when loading an editor plugin (solves problems with VST and
189 gigedit on systems with other GTK versions installed)
190
191 * audio driver:
192 - removed the nonsense audio channel constraint (which was hard coded to
193 max. 100 audio channels) for most audio drivers
194 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
195 opposed to the LSCP specs
196 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
197 reflected the wrong value
198 - fixed a memory management bug in ASIO driver
199 - Makefile fix: JACK_CFLAGS wasn't used
200 - JACK: use jack_client_open instead of the deprecated
201 jack_client_new
202 - added (experimental) CoreAudio driver
203 - applied old fixes to the ASIO driver that were included in the
204 previous binary release but accidentally never committed to CVS
205 (fixes #117)
206 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
207 win64)
208 - VST: added support for sample rate and buffer size changes
209 - VST: close editor (Fantasia) when the VST is removed
210 - VST: avoid opening Fantasia more than once for each VST instance
211 - VST: export main function as "main" on Linux too (fix for
212 energyXT)
213 - VST: changed number of output channels from one stereo to 16
214 stereo
215 - added channel routing, fxsends and midi maps to the settings
216 stored in the plugin state
217 - performance optimization of AudioChannel::MixTo() and
218 AudioChannel::CopyTo() methods using GCC vector exensions
219 (if available)
220 - ASIO fixes: avoid initializing the device twice, avoid throwing
221 exception when getting parameters from a disconnected device
222
223 * MIDI driver:
224 - added JACK MIDI driver
225 - dispatch bank select as ordinary CC as well, the user might seriously
226 want to (mis)use it for some purpose ("fixed" in all current MIDI
227 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
228 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
229 CoreMidi or AU
230 - fixed mingw-w64 compilation error in MME driver
231 - made program change handling in MIDI thread real-time safe by
232 moving the logic to a non-RT thread
233 - fixed minor memory leak in ALSA driver
234
235 * instruments database:
236 - avoid time consuming samples scanning when adding instruments
237 to the instruments database
238 - added support for handling lost files in the instruments database
239 - Implemented option for adding instruments in separate directories
240 in the instruments database
241 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
242 - work-around for missing fnmatch function on Windows to make
243 instrument database compilable
244 - added instrument database support on Windows
245 works with both standalone mode and VST plugin.
246 the instruments DB file is located in
247 %USERPROFILE%\.linuxsampler\instruments.db which allows different
248 databases for each windows user
249 if no DB is present it automatically creates the .linuxsampler subdir
250 and then creates an empty DB
251 - fixed recursive import, which was broken on Windows
252
253 * Gigasampler format engine:
254 - fixed a memory leak that could happen when a channel was deleted
255 while notes were playing
256 - made it possible to load an instrument even if the audio thread
257 isn't running
258 - added partial support for the "Controller Triggered" MIDI rule,
259 enough for piano gigs with pedal noise samples
260 - minor fix: only mark FX sends as being modified if really the
261 respective FX send MIDI controller was used
262 - added support for GM global device volume SysEx message
263 (can be selected at compile time to either apply globally to the
264 whole sampler [default] or only to the sampler channels that are
265 connected to the respective MIDI input port the SysEx message arrived
266 on)
267 - bugfix: notes triggered at position 0 in the audio buffer were
268 sometimes wrongly killed in the same buffer, causing no sound to
269 be played
270 - added support for chromatic / drumkit mode Roland GS Sysex message
271 which is usally used to switch a part between chromatic sounds and
272 drumkit sounds (as opposed to their common default setting of MIDI
273 part 10 being a drumkit part and all other ones chromatic parts), in
274 LS however one can switch between the first 16 MIDI instrument maps
275 defined for the sampler
276 - made it possible to create multiple sample channels even if the
277 audio thread isn't running
278 - fixed crash when removing channel with active voices (#116)
279 - bugfix: on sample reference changes (instrument editor), only
280 un-cache the respective sample if it's really not used by any
281 sampler engine anymore
282 - re-cache samples in case they were changed by an instrument editor,
283 e.g. when a sample was added while playing (#82)
284 - fixed hanging notes which occured when note-off event had the exact
285 same time stamp as the voice's note-on event and occured both in the
286 same audio fragment cycle (fixes bug #112)
287 - added support for the "fine tune" and "pitch bend range"
288 instrument-level gig parameters
289 - fixed minor artifacts in pitch bend handling
290 - added support for GS Reset SysEx message
291 - allow gig files to use unlimited downward pitch shifting
292 - added a limit check for upward pitch shifting
293 - bugfix: sometimes, when playing a note twice fast, the second
294 note was silent
295 - fixed crash happening when a pitch bend event arrived at the
296 same time a new instrument was loading
297
298 * LSCP server:
299 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
300 react on MIDI data arriving on certain sampler channels (so far only
301 Note-On and Note-Off events are sent via this LSCP event)
302 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
303 react on MIDI data arriving on certain MIDI input devices (so far only
304 Note-On and Note-Off events are sent via this LSCP event)
305 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
306 SET DB_INSTRUMENT FILE_PATH
307 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
308 frontends to send MIDI messages to specific sampler channel
309 - added two additional fields to GET FILE INSTRUMENT INFO command -
310 KEY_BINDINGS and KEYSWITCH_BINDINGS
311 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
312 was incorrect
313 - Optimized the retrieval of the MIDI instrument mappings
314 - added new LSCP command "SET VOICES" to globally alter the maximum
315 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
316 be triggered respectively
317 - added new LSCP command "SET STREAMS" to globally alter the maximum
318 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
319 which will be triggered respectively
320 - bugfix: retry if "select" returns EINTR (this fixes a crash when
321 a gigedit file dialog is opened)
322 - close all connections when LSCPServer is deleted
323 - hard close of all sockets on exit
324 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
325 driver
326
327 * Bug fixes:
328 - fixed a crash which occurs when removing a sampler channel waiting
329 to start instrument loading after another channel
330 - fixed a crash which occurs when removing a sampler channel with
331 instrument loading in progress (bug #113)
332 - fixed termination caused by uncaught exception when adding MIDI
333 instrument with PERSISTENT load mode
334 - fixed possible iterator invalidations when resetting the sampler
335 - fixed memory leaks when issuing the following LSCP commands:
336 GET AUDIO_OUTPUT_DRIVER INFO
337 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
338 GET MIDI_INPUT_DRIVER INFO
339 GET MIDI_INPUT_DRIVER_PARAMETER INFO
340 - fixed possible compilation error when sqlite is not present
341 - fixed orphaned pointers when setting maximum voices limit (bug #118)
342 - fixed crash when changing the audio output device of a sampler
343 channel with loaded instrument and start playing notes
344 - fixed endless loop in Engine::SuspendAll() (bug #120)
345 - fixed a low-level atomic load function that was broken on 64-bit
346 PowerPC, which probably could cause crashes on that platform
347 - fixed a memory management error which could cause a crash when a
348 plugin was unloaded
349 - bugfix: two private structs had the same name, which could cause
350 problems if the linker chose the wrong constructor
351 - fixed low-level ConditionServer usage bug that caused lockups on
352 Windows
353
354
355 Version 0.5.1 (6 December 2007)
356
357 * packaging changes:
358 - added autoconf checks for pthread library
359 - added autoconf check for pthread bug found on certain NPTL-enabled
360 glibc versions (see Gentoo bug report #194076)
361 - added autoconf checks for MS Windows
362
363 * general changes:
364 - bugfix: the thread used by an editor plugin didn't die when the
365 editor closed
366 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
367 out all the space. operator--() did not apply size_mask after
368 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
369 order to avoid problems with the _NonVolatileReader functions.
370 - bugfix: Stream.h: added a missing divide by BytesPerSample in
371 GetWriteSpace(). Since this function is currently only used in
372 the stream's qsort() compare function, it didn't trigger any
373 bugs.
374 - Resampler.h, Synthesizer.h: cubic interpolation now works in
375 24bit mode too. Faster method to read 24bit words on little
376 endian machines (x86): replaced 3 byte reads + shifts with a 1
377 unaligned 32bit read and shift
378 - experimental support for MS Windows (MIDI input via MME, AUDIO
379 output via ASIO)
380 - made handling of SIGINT signal (Ctrl-C) a bit more robust
381 - support for monitoring the total number of active disk streams
382 (new LSCP commands: GET TOTAL_STREAM_COUNT,
383 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
384
385 * AUDIO driver:
386 - added Windows ASIO low latency audio driver
387
388 * MIDI driver:
389 - added MME Windows MIDI driver
390
391 * LSCP server:
392 - added support for Windows style path / filenames, however with
393 forward slash path separators instead of backslash
394 (i.e. "C:/foo/bar.gig")
395 - allow naughty liblscp to send non-string device parameters within
396 apostrophes as well
397 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
398 "LIST FILE INSTRUMENTS <file>" and
399 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
400 about an arbitrary instrument file on the system where the sampler is
401 running on
402
403 Version 0.5.0 (15 October 2007)
404
405 * packaging changes:
406 - config.h is not going to be installed along with liblinuxsampler's
407 API header files anymore
408 - only the API relevant header (and source) files will be exported to
409 the Doxygen API documentation (explicitly listed in Doxyfile.in)
410 - added completely new XCode project files for Mac OSX which is now
411 capable to execute our autoconf environment, thus no need anymore
412 to maintain the compile time configuration file (osx/version.h) for
413 OSX manually (patch by Toshi Nagata)
414 - fixed buggy boolean --enable-foo / --disable-foo configure script
415 parameters
416 - global.h now only covers global definitions that are needed for the
417 C++ API header files, all implementation internal global definitions
418 are now in global_private.h
419 - atomic.h is not exposed to the C++ API anymore
420 - no need to include config.h anymore for using LS's API header files
421 - fixed warnings in API doc generation
422
423 * general changes:
424 - replaced the old, confusing MIDI program change mechanism by a
425 flexible MIDI instrument mapper which allows to map arbitrary
426 (MIDI bank, MIDI program) pairs with arbitrary
427 (engine type, instrument file, file index) triplets which will be
428 loaded on the respective channel when such MIDI program change
429 messages arrive, beside that, each entry allows to define a life-time
430 strategy for the instrument, so the user can define whether the
431 instrument should i.e. be permanently loaded (to be able to switch
432 quickly among sounds) or i.e. loaded just on demand when the
433 respective program change arrives (to safe RAM space), as well as a
434 global volume factor for each entry, so the user can adjust the volume
435 dynamic of his mapped instrument collection without having to modify
436 the instrument files, also one can manage arbitrary amount of such
437 MIDI instrument maps and assign each sampler channel individually
438 a certain map, so that i.e. separation of normal instruments and
439 drumkits is possible
440 - new notification events for tracking changes to audio/MIDI devices,
441 MIDI instrument maps, MIDI instruments, FX sends, global volume.
442 - sampler was limited to load max. 200 instruments in the background
443 due to a constant size RingBuffer FIFO which is now replaced by a
444 dynamic (unlimited) size std::list FIFO
445 - added FX sends, these allow to route audio signals to arbitrary audio
446 output channels for being processed by external effect processors
447 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
448 controllers
449 - global (sampler wide) volume can now be controlled at runtime
450 - Implemented new, improved notification system
451 - fixed compilation errors regarding OSX
452 (patch by Toshi Nagata)
453 - implemented instruments database
454 - added support for escape sequences to the instruments database
455 - added highly experimental support for on-the-fly instrument editing
456 within the sampler's process (by using instrument editor plugins),
457 you'll notice the new "Registered instrument editors:" message on
458 startup, added a new LSCP command:
459 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
460 to spawn a matching instrument editor for the instrument on the
461 given sampler channel, the plugin path can be overridden at compile
462 time with ./configure --enable-plugin-dir=/some/dir
463 - added experimental code for synchronizing instrument editors hosted
464 in the sampler's process to safely edit instruments while playing
465 without a crash (hopefully) by either suspending single regions
466 wherever possible or if unavoidable whole engine(s)
467 - fixed several issues in fundamental "Thread" class: set scheduling
468 policy and priority on thread level, set a minimum stack size for
469 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
470 threads simply inherited properties of starting thread instead of
471 setting their own policy and priority
472 - minor fix in our automatic stack trace mechanism on crashes, the
473 main process did not wait for the stack trace process to finish
474 its output
475 - fixed some minor memory leaks
476 - reenabled assembly features support, at the moment only for
477 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
478 - minor assembly fix in x86 features detection (don't use the PIC
479 register, to avoid relocations in the text segment at runtime)
480 - POSIX callback functions of Thread.h are hidden
481
482 * MIDI driver:
483 - dispatch bank select (MSB and LSB) messages
484
485 * audio driver:
486 - the ALSA audio output driver parameters now reflect the correct
487 parameter value ranges for the respective selected sound card
488 (patch by Till Wimmer, a bit fixed and extended)
489
490 * Gigasampler format engine:
491 - if a filter is used and EG2 finishes before EG1, let the voice
492 die when EG2 has finished (this fixes a problem with clicks and
493 voice starvation for some gigs)
494 - playback is no longer disabled during instrument loading
495 - all notes playing on a channel that changes its instrument keep
496 playing with the old instrument until they get a note off
497 command
498 - EG fix: a release value of zero could cause noises or crash
499 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
500 - EG fine tuning: when attack is zero the EG starts at a level
501 above max sustain level, which means that there is a decay phase
502 even if sustain is 100%
503 - more EG fixes: the level could sometimes go below zero and cause
504 noises or crashes
505 - minor fix of EGDecay (patch by Toshi Nagata)
506 - fixed compiler error when --enable-override-filter-type was
507 supplied to the configure script (fixes #46)
508 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
509 instead of a fix value
510 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
511 127 (solo mode) only kill voices if the respective mode really
512 changed
513
514 * LSCP server:
515 - fixed compile time error for old Bison versions
516 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
517 - parser now supports extended ASCII character set
518 (up to ASCII code 255, i.e. includes now umlauts and accents)
519 - filename arguments in LSCP commands now allow to use escape
520 sequences, that is directly literal as one of: \', \", \\, \n, \r,
521 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
522 code value like \xf2) (fixes bug #24)
523 - the following LSCP commands now also support escape sequences for at
524 least one of their text-based parameters (i.e. name, description):
525 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
526 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
527 "SET DB_INSTRUMENT_DIRECTORY NAME",
528 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
529 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
530 "FIND DB_INSTRUMENT_DIRECTORIES"
531 - returns verbose syntax errors (line and column where syntax error
532 occured, the unexpected character and the actually expected, possible
533 character(s), the latter only if less than 5 possibilities)
534 - made sure that LSCP syntax is not affected by gigedit locale
535 settings
536 - bugfix regarding strings parameter lists: all comma separated lists
537 of strings were treated as being one string containing commas
538 (fixes #57)
539
540 * Bug fixes:
541 - fixed crash occurring on certain LSCP scripts (Bug 39)
542 - another thread safety fix for lscp "load engine" and "set
543 channel audio output device"
544 - fixed a crash which occurs when reassigning the same engine
545 on a sampler channel with connected MIDI device
546 - fixed a crash which occurs when changing the number of ports of a MIDI
547 device connected to a sampler channel to number less then or equal
548 to the index of the port to which the sampler channel is connected.
549 - The previous bindings were not been disconnected when altering
550 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
551 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
552 - The active stream/voice count statistic was incorrect.
553 - notification events were not been sent for some sampler
554 channel changes
555 - added default min and max values to restrict the number of allowed
556 audio output channels and MIDI input ports
557 - the connection to the PCM interface is now closed when destroying
558 an audio output device
559 - files with slash in their path or filename could not be loaded
560
561 * test cases:
562 - updated and fixed (haven't been touched in a while)
563
564 Version 0.4.0 (24 November 2006)
565
566 * packaging changes:
567 - changed deprecated copyright attribute to license; added ldconfig
568 to post-(un)install steps; added devel package for liblinuxsampler;
569 to linuxsampler.spec (RPM)
570 - install necessary development header files for allowing 3rd party
571 applications to link against liblinuxsampler
572 - liblinuxsampler's API documentation can be generated with 'make docs'
573 (Doxygen required)
574 - added benchmark to automatically detect the best triangle LFO
575 implementation (currently either an integer math solution or a
576 di-harmonic approximation), automatic detection can be overriden
577 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
578 configure script argument though (mandatory for cross-compilation)
579 - do not automatically pick optimized gcc flags if the user already
580 provided some on his own (as CXXFLAGS)
581 - added compile time option to disable processing of All-Notes-Off MIDI
582 messages
583 - added compile time options to allow disabling the various audio and
584 MIDI drivers
585 - fixed automatic GCC CPU switch detection on PPC
586 (patch by Ebrahim Mayat)
587
588 * Gigasampler format engine:
589 - extensive synthesis optimization
590 (reimplementation of EGs and LFO(s), removed synthesis parameter
591 prerendering and the synthesis parameter matrix in general, splitting
592 each audio fragment into subfragments now where each subfragment uses
593 constant pitch and filter coefficients. The volume coefficient is
594 linearly interpolated inside a subfragment, unless
595 --disable-interpolate-volume is set.)
596 - fine tuning of the EG modulation parameters
597 - improved filter cutoff calculation by adding support for the
598 following gig parameters: Cutoff freq (used when no cutoff
599 controller is defined), Control invert, Minimum cutoff, Velocity
600 curve and Velocity range. The keyboard tracking now scales
601 cutoff frequency instead of resonance.
602 - added support for gig parameter Resonance.
603 - fixed bug in sysex handling (patch by Juan Linietsky)
604 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
605 which can be overridden with --enable-global-attenuation
606 - EG fixes: made the length of "attack hold" stage more
607 accurate. Release stage can now start before attack stage
608 ends. Cancel release didn't work when sustain was zero. Attack
609 time now has a minimal value to prevent clicks.
610 - fixed pitch changes larger than one octave
611 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
612 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
613 all modes can be altered via standard GM messages, that is CC5 for
614 altering portamento time, CC65 for enabling / disabling portamento
615 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
616 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
617 parameter) and crossfade
618 - added support for the "attenuation controller threshold" gig
619 parameter
620 - added smoothing of volume changes caused by control change
621 messages
622 - sample loop parameters are now taken from the DimensionRegion
623 instead of the wave chunk
624 - fixed keyswitching for v3 gigs with a number of keyswitch splits
625 not equal to a power of two
626 - reimplementation of the filter algorithm. The new filter is more
627 accurate and supports all gig filter types, including bandreject
628 and lowpass turbo.
629 - real support for 24 bit samples - samples are not truncated to
630 16 bits anymore
631 - support for aftertouch (channel pressure, not polyphonic
632 aftertouch)
633 - LFO1 behaviour fixed (dampening from max volume instead of
634 amplifying from 0)
635
636 * LSCP server:
637 - fixed application exit on broken pipe error (fixes bug #20)
638 - fixed the notification messages delay due to lack of
639 network activity (fixes bug #26)
640 - fixed parser bug which occured on space(s) within device parameters
641 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
642
643 * audio driver:
644 - added aRts audio output driver (by no means RT safe)
645
646 * MIDI driver:
647 - fixed legacy sysex code which caused dispatching of MIDI SysEx
648 messages several times instead of once
649 - API extension for MIDI drivers which already supply exact time stamps
650 for events (i.e. for offline rendering based MIDI drivers)
651 - added checks for bad MIDI data
652
653 * linuxsampler application:
654 - show available sampler engine types on startup
655
656 * general changes:
657 - support for muting sampler channels and solo mode of the same, two new
658 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
659 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
660 introduced for this, the behavior is the same like on a mixer console
661 (patch by Grigor Iliev, a bit adjusted). Also added configure option
662 --enable-process-muted-channels which can be used to enable the
663 processing of muted channels.
664 - support for sostenuto pedal
665 - support for monitoring the total number of active voices
666 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
667 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
668 - fixed some memory management errors
669 - fixed some concurrency problems that could lead to crashes when
670 LSCP commands were executed
671 - fixed crash when instrument loading failed previously on the same
672 sampler channel (fixes bug #36)
673
674 Version 0.3.3 (15 July 2005)
675
676 * packaging changes:
677 - fixed compilation with gcc 4.0
678
679 * Gigasampler format engine:
680 - LFO preprocessing was performed even though the respective LFO was
681 disabled by the instrument patch (minor efficiency fix)
682 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
683 for volume ramp downs in the same fragment (needed for current voice
684 stealing implementation) then simply inform the user with a warning
685 about possible click sounds and reduce the volume ramp down
686 appropriately instead of cancelling the audio device connection
687
688 Version 0.3.2 (24 June 2005)
689
690 * packaging changes:
691 - updated autotools build files to compile on OS X
692 (conditional compilation of CoreMIDI and MidiShare drivers)
693 - hand-crafted assembly optimization code can be disabled with
694 './configure --disable-asm' (definitely not recommended)
695 - fixed 'make dist' rule to include all necessary files
696 - require automake (>= 1.5) for 'make -f Makefile.cvs'
697 (due to 'dist-bzip2' automake option)
698
699 * Gigasampler format engine:
700 - support for the gig parameters for "release velocity response" curves
701 - fine tuning of the EGADSR envelope
702 - volume of release triggered samples now depends on note-on velocity,
703 note length and gig parameter "release trigger decay" instead of
704 note-off velocity.
705 - revised voice stealing
706 (fixes crash and endless loop caused by voice stealing)
707 - don't reset scale tuning on instrument or audio output device change
708 - handle key group conflicts right at the beginning of each fragment
709 instead of when the respective voice is actually launched
710 (fixes undefined behavior if stolen voices belonged to a key group -
711 this case was followed by a "killed voice survived" error message)
712 - fixed minor issue with null/silence samples
713 (those stole voices even though they don't need a voice at all which
714 resulted in "voice stealing didn't work out" messages)
715 - don't reset volume, pan, pitch and MIDI controller values on
716 instrument or audio output device change
717
718 * LSCP server:
719 - fixed some crashes (patch by Grigor Iliev, fixes #19)
720 - fixed LSCP event "CHANNEL_INFO" notification
721 (e.g. did not notify on volume changes or MIDI program change events)
722
723 * linuxsampler application:
724 - added command line parameters --lscp-addr and --lscp-port to override
725 default IP address and port of LSCP server
726
727 Version 0.3.1 (24 May 2005)
728
729 * initial release
