1 Version CVS HEAD (?)
3 * packaging changes:
4 - fixed building with newer MinGW-w64
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).
16 * Gigasampler format engine:
17 - implemented the "round robin keyboard" dimension
18 - fixed round robin and random dimensions for cases when number of
19 dimension zones is not a power of two
20 - made round robin use a counter for each region instead of each
21 key
23 * SFZ format engine:
24 - Initial implementation (not usable yet)
25 - added support for v2 multiple stage envelope generators
26 - added a fine-tuned v1 envelope generator instead of using the
27 one from the gig engine
28 - fixed memory leak and memory handling errors
29 - added support for trigger=first, trigger=legato and sw_previous
30 - allow non-numerical key values ("C#4" for example)
31 - "key" opcode now sets pitch_keycenter too
32 - fixed error when unloading instrument with same sample used by
33 multiple regions
34 - added some opcode aliases, like loopmode for loop_mode, to be
35 more compatible
36 - added support for trigger=release and rt_decay
37 - added support for off_mode=normal
38 - added support for random, seq_position, seq_length and volume
39 - added v1 LFO opcodes to parser (no support in engine yet)
40 - added support for amp_veltrack and amp_velcurve_N
41 - fine-tuned the default velocity curve

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