* bugfix: playing a note while changing the instrument could cause a
  crash, or give "Handing back unknown region" error messages

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).
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)
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
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
51 - added support for random, seq_position, seq_length and volume
52 - added v1 LFO opcodes to parser (no support in engine yet)
53 - added support for amp_veltrack and amp_velcurve_N
54 - fine-tuned the default velocity curve
55 - added support for transpose
56 - fixed crash when using sw_down/up
57 - improved logic for sw_lokey/hikey/up/down/last
58 - added more v1 aliases to parser
59 - reduced memory usage for sfz data
60 - RT-safeness: avoid malloc in audio thread
61 - fixed a bug that could cause voice stealing to fail
62 - optimized sample lookup
63 - improved support for exclusive groups (group, off_by and
64 off_mode)
65 - added support for controller triggered regions (on_locc/on_hicc)
66 - added support for loop_mode=one_shot
67 - fixed playback of 16 bit wav files on big endian CPUs
68 - added support for Ogg Vorbis sample files
70 * SoundFont format engine:
71 - Initial implementation (not usable yet)
72 - RT-safeness: avoid malloc in audio thread
73 - fixed a bug that could cause voice stealing to fail
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.
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
86 there is no reason for this limit
88 * LSCP server:
89 - added support for sending MIDI CC messages via LSCP command
90 "SEND CHANNEL MIDI_DATA CC <sampler-chan> <ctrl> <val>"

113 <effect-chain> <effect-instance>"
114 - added LSCP command "INSERT SEND_EFFECT_CHAIN EFFECT <audio-device>
115 <effect-chain> <effect-chain-pos> <effect-instance>"
116 - added LSCP command "REMOVE SEND_EFFECT_CHAIN EFFECT <audio-device>

128 type while an instrument load was in progress
129 - bugfix: playing a note while changing the instrument could cause
130 a crash, or give "Handing back unknown region" error messages
132 Version 1.0.0 (31 July 2009)
134 * packaging changes:
135 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
136 causing e.g. the libgig test to fail when
137 "./configure --disable-jack-driver" was used
138 (patch by Alexis Ballier)
139 - fixed compilation with gcc 4.3
140 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
141 - fixed configure so it detects x86_64 (#107)
142 - fixes for building with newer MinGW versions
143 - fix for building with bison 2.4 (#111)
144 - fixed building with libgig installed in a non-standard directory
145 - minor fix in configure for mmsystem.h detection on MinGW
146 - Windows: look for editor plugins and Fantasia using base
147 directory of liblinuxsampler dll (look in the same directory and one
148 directory above)
149 - configure script fix: removed unconditional use of SSE
150 - fixed building with sqlite installed in a non-standard directory
151 - when cross-compiling, don't try to create instruments.db
152 - fix for new mingw-w64 version, which has usleep
154 * general changes:
155 - bugfix: on some POSIX systems instrument editor plugins refused to
156 load as we used a non-portable Linux specific struct field
157 (fixes bug #70, patch by Ronald Baljeu)
158 - fixed endless loop which occured when loading an instrument editor
159 plugin DLL on Windows systems failed
160 - fixed memory leaks that occurred when liblinuxsampler was unloaded
161 - optimized the SynchronizedConfig class so it doesn't wait
162 unnecessarily long after an update
163 - added support for notifying instrument editors on note-on / note-off
164 events (e.g. to highlight the pressed keys on the virtual keyboard
165 of gigedit)
166 - added support for triggering notes by instrument editors (see above)
167 - be verbose on DLL load errors (on Linux)
168 - fixed di-harmonic triangle LFO implementation (this LFO implementation
169 is only used by very few systems, most pick the int math
170 implementation, which is usually faster)
171 - fixes for audio drivers with varying buffer sizes
172 - experimental support for running LinuxSampler as a DSSI, LV2 and
173 VST plugin
174 - notification events for stream/voice count statistics are now sent
175 only when there are actual changes
176 - added memory ordering constraints to improve stability on
177 multi-core and multi-cpu systems
178 - maximum voices and disk streams can now be altered at runtime
179 - fixed CPU feature detection on x86_64 (maybe fixes #108)
180 - automatic stacktrace mechanism is now turned off by default and can
181 be switched on by command line option "--stacktrace" (the automatic
182 stacktrace mechanism seems to be broken on most systems at the moment)
183 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
184 a pointer to the launched InstrumentEditor object
185 - added optional 3rd party user data parameter for following
186 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
187 InstrumentEditor::Launch(),
188 InstrumentManager::LaunchInstrumentEditor()
189 - theoretical fix: made SynchronizedConfig follow C++0x memory
190 model more strictly
191 - fixes for using large audio device buffers
192 - Windows: add the installation directory to the DLL search path
193 when loading an editor plugin (solves problems with VST and
194 gigedit on systems with other GTK versions installed)
196 * audio driver:
197 - removed the nonsense audio channel constraint (which was hard coded to
198 max. 100 audio channels) for most audio drivers
199 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
200 opposed to the LSCP specs
201 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
202 reflected the wrong value
203 - fixed a memory management bug in ASIO driver
204 - Makefile fix: JACK_CFLAGS wasn't used
205 - JACK: use jack_client_open instead of the deprecated
206 jack_client_new
207 - added (experimental) CoreAudio driver
208 - applied old fixes to the ASIO driver that were included in the
209 previous binary release but accidentally never committed to CVS
210 (fixes #117)
211 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
212 win64)
213 - VST: added support for sample rate and buffer size changes
214 - VST: close editor (Fantasia) when the VST is removed
215 - VST: avoid opening Fantasia more than once for each VST instance
216 - VST: export main function as "main" on Linux too (fix for
217 energyXT)
218 - VST: changed number of output channels from one stereo to 16
219 stereo
220 - added channel routing, fxsends and midi maps to the settings
221 stored in the plugin state
222 - performance optimization of AudioChannel::MixTo() and
223 AudioChannel::CopyTo() methods using GCC vector exensions
224 (if available)
225 - ASIO fixes: avoid initializing the device twice, avoid throwing
226 exception when getting parameters from a disconnected device
228 * MIDI driver:
229 - added JACK MIDI driver
230 - dispatch bank select as ordinary CC as well, the user might seriously
231 want to (mis)use it for some purpose ("fixed" in all current MIDI
232 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
233 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
234 CoreMidi or AU
235 - fixed mingw-w64 compilation error in MME driver
236 - made program change handling in MIDI thread real-time safe by
237 moving the logic to a non-RT thread
238 - fixed minor memory leak in ALSA driver
240 * instruments database:
241 - avoid time consuming samples scanning when adding instruments
242 to the instruments database
243 - added support for handling lost files in the instruments database
244 - Implemented option for adding instruments in separate directories
245 in the instruments database
246 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
247 - work-around for missing fnmatch function on Windows to make
248 instrument database compilable
249 - added instrument database support on Windows
250 works with both standalone mode and VST plugin.
251 the instruments DB file is located in
252 %USERPROFILE%\.linuxsampler\instruments.db which allows different
253 databases for each windows user
254 if no DB is present it automatically creates the .linuxsampler subdir
255 and then creates an empty DB
256 - fixed recursive import, which was broken on Windows
258 * Gigasampler format engine:
259 - fixed a memory leak that could happen when a channel was deleted
260 while notes were playing
261 - made it possible to load an instrument even if the audio thread
262 isn't running
263 - added partial support for the "Controller Triggered" MIDI rule,
264 enough for piano gigs with pedal noise samples
265 - minor fix: only mark FX sends as being modified if really the
266 respective FX send MIDI controller was used
267 - added support for GM global device volume SysEx message
268 (can be selected at compile time to either apply globally to the
269 whole sampler [default] or only to the sampler channels that are
270 connected to the respective MIDI input port the SysEx message arrived
271 on)
272 - bugfix: notes triggered at position 0 in the audio buffer were
273 sometimes wrongly killed in the same buffer, causing no sound to
274 be played
275 - added support for chromatic / drumkit mode Roland GS Sysex message
276 which is usally used to switch a part between chromatic sounds and
277 drumkit sounds (as opposed to their common default setting of MIDI
278 part 10 being a drumkit part and all other ones chromatic parts), in
279 LS however one can switch between the first 16 MIDI instrument maps
280 defined for the sampler
281 - made it possible to create multiple sample channels even if the
282 audio thread isn't running
283 - fixed crash when removing channel with active voices (#116)
284 - bugfix: on sample reference changes (instrument editor), only
285 un-cache the respective sample if it's really not used by any
286 sampler engine anymore
287 - re-cache samples in case they were changed by an instrument editor,
288 e.g. when a sample was added while playing (#82)
289 - fixed hanging notes which occured when note-off event had the exact
290 same time stamp as the voice's note-on event and occured both in the
291 same audio fragment cycle (fixes bug #112)
292 - added support for the "fine tune" and "pitch bend range"
293 instrument-level gig parameters
294 - fixed minor artifacts in pitch bend handling
295 - added support for GS Reset SysEx message
296 - allow gig files to use unlimited downward pitch shifting
297 - added a limit check for upward pitch shifting
298 - bugfix: sometimes, when playing a note twice fast, the second
299 note was silent
300 - fixed crash happening when a pitch bend event arrived at the
301 same time a new instrument was loading
303 * LSCP server:
304 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
305 react on MIDI data arriving on certain sampler channels (so far only
306 Note-On and Note-Off events are sent via this LSCP event)
307 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
308 react on MIDI data arriving on certain MIDI input devices (so far only
309 Note-On and Note-Off events are sent via this LSCP event)
310 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
312 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
313 frontends to send MIDI messages to specific sampler channel
314 - added two additional fields to GET FILE INSTRUMENT INFO command -
316 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
317 was incorrect
318 - Optimized the retrieval of the MIDI instrument mappings
319 - added new LSCP command "SET VOICES" to globally alter the maximum
320 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
321 be triggered respectively
322 - added new LSCP command "SET STREAMS" to globally alter the maximum
323 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
324 which will be triggered respectively
325 - bugfix: retry if "select" returns EINTR (this fixes a crash when
326 a gigedit file dialog is opened)
327 - close all connections when LSCPServer is deleted
328 - hard close of all sockets on exit
329 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
330 driver
332 * Bug fixes:
333 - fixed a crash which occurs when removing a sampler channel waiting
334 to start instrument loading after another channel
335 - fixed a crash which occurs when removing a sampler channel with
336 instrument loading in progress (bug #113)
337 - fixed termination caused by uncaught exception when adding MIDI
338 instrument with PERSISTENT load mode
339 - fixed possible iterator invalidations when resetting the sampler
340 - fixed memory leaks when issuing the following LSCP commands:
345 - fixed possible compilation error when sqlite is not present
346 - fixed orphaned pointers when setting maximum voices limit (bug #118)
347 - fixed crash when changing the audio output device of a sampler
348 channel with loaded instrument and start playing notes
349 - fixed endless loop in Engine::SuspendAll() (bug #120)
350 - fixed a low-level atomic load function that was broken on 64-bit
351 PowerPC, which probably could cause crashes on that platform
352 - fixed a memory management error which could cause a crash when a
353 plugin was unloaded
354 - bugfix: two private structs had the same name, which could cause
355 problems if the linker chose the wrong constructor
356 - fixed low-level ConditionServer usage bug that caused lockups on
357 Windows
360 Version 0.5.1 (6 December 2007)
362 * packaging changes:
363 - added autoconf checks for pthread library
364 - added autoconf check for pthread bug found on certain NPTL-enabled
365 glibc versions (see Gentoo bug report #194076)
366 - added autoconf checks for MS Windows
368 * general changes:
369 - bugfix: the thread used by an editor plugin didn't die when the
370 editor closed
371 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
372 out all the space. operator--() did not apply size_mask after
373 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
374 order to avoid problems with the _NonVolatileReader functions.
375 - bugfix: Stream.h: added a missing divide by BytesPerSample in
376 GetWriteSpace(). Since this function is currently only used in
377 the stream's qsort() compare function, it didn't trigger any
378 bugs.
379 - Resampler.h, Synthesizer.h: cubic interpolation now works in
380 24bit mode too. Faster method to read 24bit words on little
381 endian machines (x86): replaced 3 byte reads + shifts with a 1
382 unaligned 32bit read and shift
383 - experimental support for MS Windows (MIDI input via MME, AUDIO
384 output via ASIO)
385 - made handling of SIGINT signal (Ctrl-C) a bit more robust
386 - support for monitoring the total number of active disk streams
387 (new LSCP commands: GET TOTAL_STREAM_COUNT,
390 * AUDIO driver:
391 - added Windows ASIO low latency audio driver
393 * MIDI driver:
394 - added MME Windows MIDI driver
396 * LSCP server:
397 - added support for Windows style path / filenames, however with
398 forward slash path separators instead of backslash
399 (i.e. "C:/foo/bar.gig")
400 - allow naughty liblscp to send non-string device parameters within
401 apostrophes as well
402 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
403 "LIST FILE INSTRUMENTS <file>" and
404 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
405 about an arbitrary instrument file on the system where the sampler is
406 running on
408 Version 0.5.0 (15 October 2007)
410 * packaging changes:
411 - config.h is not going to be installed along with liblinuxsampler's
412 API header files anymore
413 - only the API relevant header (and source) files will be exported to
414 the Doxygen API documentation (explicitly listed in Doxyfile.in)
415 - added completely new XCode project files for Mac OSX which is now
416 capable to execute our autoconf environment, thus no need anymore
417 to maintain the compile time configuration file (osx/version.h) for
418 OSX manually (patch by Toshi Nagata)
419 - fixed buggy boolean --enable-foo / --disable-foo configure script
420 parameters
421 - global.h now only covers global definitions that are needed for the
422 C++ API header files, all implementation internal global definitions
423 are now in global_private.h
424 - atomic.h is not exposed to the C++ API anymore
425 - no need to include config.h anymore for using LS's API header files
426 - fixed warnings in API doc generation
428 * general changes:
429 - replaced the old, confusing MIDI program change mechanism by a
430 flexible MIDI instrument mapper which allows to map arbitrary
431 (MIDI bank, MIDI program) pairs with arbitrary
432 (engine type, instrument file, file index) triplets which will be
433 loaded on the respective channel when such MIDI program change
434 messages arrive, beside that, each entry allows to define a life-time
435 strategy for the instrument, so the user can define whether the
436 instrument should i.e. be permanently loaded (to be able to switch
437 quickly among sounds) or i.e. loaded just on demand when the
438 respective program change arrives (to safe RAM space), as well as a
439 global volume factor for each entry, so the user can adjust the volume
440 dynamic of his mapped instrument collection without having to modify
441 the instrument files, also one can manage arbitrary amount of such
442 MIDI instrument maps and assign each sampler channel individually
443 a certain map, so that i.e. separation of normal instruments and
444 drumkits is possible
445 - new notification events for tracking changes to audio/MIDI devices,
446 MIDI instrument maps, MIDI instruments, FX sends, global volume.
447 - sampler was limited to load max. 200 instruments in the background
448 due to a constant size RingBuffer FIFO which is now replaced by a
449 dynamic (unlimited) size std::list FIFO
450 - added FX sends, these allow to route audio signals to arbitrary audio
451 output channels for being processed by external effect processors
452 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
453 controllers
454 - global (sampler wide) volume can now be controlled at runtime
455 - Implemented new, improved notification system
456 - fixed compilation errors regarding OSX
457 (patch by Toshi Nagata)
458 - implemented instruments database
459 - added support for escape sequences to the instruments database
460 - added highly experimental support for on-the-fly instrument editing
461 within the sampler's process (by using instrument editor plugins),
462 you'll notice the new "Registered instrument editors:" message on
463 startup, added a new LSCP command:
464 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
465 to spawn a matching instrument editor for the instrument on the
466 given sampler channel, the plugin path can be overridden at compile
467 time with ./configure --enable-plugin-dir=/some/dir
468 - added experimental code for synchronizing instrument editors hosted
469 in the sampler's process to safely edit instruments while playing
470 without a crash (hopefully) by either suspending single regions
471 wherever possible or if unavoidable whole engine(s)
472 - fixed several issues in fundamental "Thread" class: set scheduling
473 policy and priority on thread level, set a minimum stack size for
474 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
475 threads simply inherited properties of starting thread instead of
476 setting their own policy and priority
477 - minor fix in our automatic stack trace mechanism on crashes, the
478 main process did not wait for the stack trace process to finish
479 its output
480 - fixed some minor memory leaks
481 - reenabled assembly features support, at the moment only for
482 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
483 - minor assembly fix in x86 features detection (don't use the PIC
484 register, to avoid relocations in the text segment at runtime)
485 - POSIX callback functions of Thread.h are hidden
487 * MIDI driver:
488 - dispatch bank select (MSB and LSB) messages
490 * audio driver:
491 - the ALSA audio output driver parameters now reflect the correct
492 parameter value ranges for the respective selected sound card
493 (patch by Till Wimmer, a bit fixed and extended)
495 * Gigasampler format engine:
496 - if a filter is used and EG2 finishes before EG1, let the voice
497 die when EG2 has finished (this fixes a problem with clicks and
498 voice starvation for some gigs)
499 - playback is no longer disabled during instrument loading
500 - all notes playing on a channel that changes its instrument keep
501 playing with the old instrument until they get a note off
502 command
503 - EG fix: a release value of zero could cause noises or crash
504 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
505 - EG fine tuning: when attack is zero the EG starts at a level
506 above max sustain level, which means that there is a decay phase
507 even if sustain is 100%
508 - more EG fixes: the level could sometimes go below zero and cause
509 noises or crashes
510 - minor fix of EGDecay (patch by Toshi Nagata)
511 - fixed compiler error when --enable-override-filter-type was
512 supplied to the configure script (fixes #46)
513 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
514 instead of a fix value
515 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
516 127 (solo mode) only kill voices if the respective mode really

519 * LSCP server:
520 - fixed compile time error for old Bison versions
521 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
522 - parser now supports extended ASCII character set
523 (up to ASCII code 255, i.e. includes now umlauts and accents)
524 - filename arguments in LSCP commands now allow to use escape
525 sequences, that is directly literal as one of: \', \", \\, \n, \r,
526 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
527 code value like \xf2) (fixes bug #24)
528 - the following LSCP commands now also support escape sequences for at
529 least one of their text-based parameters (i.e. name, description):
536 - returns verbose syntax errors (line and column where syntax error
537 occured, the unexpected character and the actually expected, possible
538 character(s), the latter only if less than 5 possibilities)
539 - made sure that LSCP syntax is not affected by gigedit locale
540 settings
541 - bugfix regarding strings parameter lists: all comma separated lists
542 of strings were treated as being one string containing commas
543 (fixes #57)
545 * Bug fixes:
546 - fixed crash occurring on certain LSCP scripts (Bug 39)
547 - another thread safety fix for lscp "load engine" and "set
548 channel audio output device"
549 - fixed a crash which occurs when reassigning the same engine
550 on a sampler channel with connected MIDI device
551 - fixed a crash which occurs when changing the number of ports of a MIDI
552 device connected to a sampler channel to number less then or equal
553 to the index of the port to which the sampler channel is connected.
554 - The previous bindings were not been disconnected when altering
555 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
556 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
557 - The active stream/voice count statistic was incorrect.
558 - notification events were not been sent for some sampler
559 channel changes
560 - added default min and max values to restrict the number of allowed
561 audio output channels and MIDI input ports
562 - the connection to the PCM interface is now closed when destroying
563 an audio output device
564 - files with slash in their path or filename could not be loaded
566 * test cases:
567 - updated and fixed (haven't been touched in a while)
569 Version 0.4.0 (24 November 2006)
571 * packaging changes:
572 - changed deprecated copyright attribute to license; added ldconfig
573 to post-(un)install steps; added devel package for liblinuxsampler;
574 to linuxsampler.spec (RPM)
575 - install necessary development header files for allowing 3rd party
576 applications to link against liblinuxsampler
577 - liblinuxsampler's API documentation can be generated with 'make docs'
578 (Doxygen required)
579 - added benchmark to automatically detect the best triangle LFO
580 implementation (currently either an integer math solution or a
581 di-harmonic approximation), automatic detection can be overriden
582 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
583 configure script argument though (mandatory for cross-compilation)
584 - do not automatically pick optimized gcc flags if the user already
585 provided some on his own (as CXXFLAGS)
586 - added compile time option to disable processing of All-Notes-Off MIDI
587 messages
588 - added compile time options to allow disabling the various audio and
589 MIDI drivers
590 - fixed automatic GCC CPU switch detection on PPC
591 (patch by Ebrahim Mayat)
593 * Gigasampler format engine:
594 - extensive synthesis optimization
595 (reimplementation of EGs and LFO(s), removed synthesis parameter
596 prerendering and the synthesis parameter matrix in general, splitting
597 each audio fragment into subfragments now where each subfragment uses
598 constant pitch and filter coefficients. The volume coefficient is
599 linearly interpolated inside a subfragment, unless
600 --disable-interpolate-volume is set.)
601 - fine tuning of the EG modulation parameters
602 - improved filter cutoff calculation by adding support for the
603 following gig parameters: Cutoff freq (used when no cutoff
604 controller is defined), Control invert, Minimum cutoff, Velocity
605 curve and Velocity range. The keyboard tracking now scales
606 cutoff frequency instead of resonance.
607 - added support for gig parameter Resonance.
608 - fixed bug in sysex handling (patch by Juan Linietsky)
609 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
610 which can be overridden with --enable-global-attenuation
611 - EG fixes: made the length of "attack hold" stage more
612 accurate. Release stage can now start before attack stage
613 ends. Cancel release didn't work when sustain was zero. Attack
614 time now has a minimal value to prevent clicks.
615 - fixed pitch changes larger than one octave
616 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
617 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
618 all modes can be altered via standard GM messages, that is CC5 for
619 altering portamento time, CC65 for enabling / disabling portamento
620 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
621 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
622 parameter) and crossfade
623 - added support for the "attenuation controller threshold" gig
624 parameter
625 - added smoothing of volume changes caused by control change
626 messages
627 - sample loop parameters are now taken from the DimensionRegion
628 instead of the wave chunk
629 - fixed keyswitching for v3 gigs with a number of keyswitch splits
630 not equal to a power of two
631 - reimplementation of the filter algorithm. The new filter is more
632 accurate and supports all gig filter types, including bandreject
633 and lowpass turbo.
634 - real support for 24 bit samples - samples are not truncated to
635 16 bits anymore
636 - support for aftertouch (channel pressure, not polyphonic
637 aftertouch)
638 - LFO1 behaviour fixed (dampening from max volume instead of
639 amplifying from 0)
641 * LSCP server:
642 - fixed application exit on broken pipe error (fixes bug #20)
643 - fixed the notification messages delay due to lack of
644 network activity (fixes bug #26)
645 - fixed parser bug which occured on space(s) within device parameters
648 * audio driver:
649 - added aRts audio output driver (by no means RT safe)
651 * MIDI driver:
652 - fixed legacy sysex code which caused dispatching of MIDI SysEx
653 messages several times instead of once
654 - API extension for MIDI drivers which already supply exact time stamps
655 for events (i.e. for offline rendering based MIDI drivers)
656 - added checks for bad MIDI data
658 * linuxsampler application:
659 - show available sampler engine types on startup
661 * general changes:
662 - support for muting sampler channels and solo mode of the same, two new
663 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
664 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
665 introduced for this, the behavior is the same like on a mixer console
666 (patch by Grigor Iliev, a bit adjusted). Also added configure option
667 --enable-process-muted-channels which can be used to enable the
668 processing of muted channels.
669 - support for sostenuto pedal
670 - support for monitoring the total number of active voices
673 - fixed some memory management errors
674 - fixed some concurrency problems that could lead to crashes when
675 LSCP commands were executed
676 - fixed crash when instrument loading failed previously on the same
677 sampler channel (fixes bug #36)
679 Version 0.3.3 (15 July 2005)
681 * packaging changes:
682 - fixed compilation with gcc 4.0
684 * Gigasampler format engine:
685 - LFO preprocessing was performed even though the respective LFO was
686 disabled by the instrument patch (minor efficiency fix)
687 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
688 for volume ramp downs in the same fragment (needed for current voice
689 stealing implementation) then simply inform the user with a warning
690 about possible click sounds and reduce the volume ramp down
691 appropriately instead of cancelling the audio device connection
693 Version 0.3.2 (24 June 2005)
695 * packaging changes:
696 - updated autotools build files to compile on OS X
697 (conditional compilation of CoreMIDI and MidiShare drivers)
698 - hand-crafted assembly optimization code can be disabled with
699 './configure --disable-asm' (definitely not recommended)
700 - fixed 'make dist' rule to include all necessary files
701 - require automake (>= 1.5) for 'make -f Makefile.cvs'
702 (due to 'dist-bzip2' automake option)
704 * Gigasampler format engine:
705 - support for the gig parameters for "release velocity response" curves
706 - fine tuning of the EGADSR envelope
707 - volume of release triggered samples now depends on note-on velocity,
708 note length and gig parameter "release trigger decay" instead of
709 note-off velocity.
710 - revised voice stealing
711 (fixes crash and endless loop caused by voice stealing)
712 - don't reset scale tuning on instrument or audio output device change
713 - handle key group conflicts right at the beginning of each fragment
714 instead of when the respective voice is actually launched
715 (fixes undefined behavior if stolen voices belonged to a key group -
716 this case was followed by a "killed voice survived" error message)
717 - fixed minor issue with null/silence samples
718 (those stole voices even though they don't need a voice at all which
719 resulted in "voice stealing didn't work out" messages)
720 - don't reset volume, pan, pitch and MIDI controller values on
721 instrument or audio output device change
723 * LSCP server:
724 - fixed some crashes (patch by Grigor Iliev, fixes #19)
725 - fixed LSCP event "CHANNEL_INFO" notification
726 (e.g. did not notify on volume changes or MIDI program change events)
728 * linuxsampler application:
729 - added command line parameters --lscp-addr and --lscp-port to override
730 default IP address and port of LSCP server
732 Version 0.3.1 (24 May 2005)
734 * initial release
