* implemented Roland GS NRPN 1ArrH which allows to set volume per note
* implemented Roland GS NRPN 1CrrH which allows to set pan per note
* implemented Roland GS NRPN 1DrrH which allows to set reverb send per
  note (in this implementation of the sampler its simply hard routed to
  the 1st effect send of the sampler channel, no matter what the actual
  effect type is)
* implemented Roland GS NRPN 1ErrH which allows to set chorus send per
  note (in this implementation of the sampler its simply hard routed to
  the 2nd effect send of the sampler channel, no matter what the actual
  effect type is)
* bumped version to 1.0.0cvs4

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)
26 * Gigasampler format engine:
27 - implemented the "round robin keyboard" dimension
28 - fixed round robin and random dimensions for cases when number of
29 dimension zones is not a power of two
30 - made round robin use a counter for each region instead of each
31 key
33 * SFZ format engine:
34 - Initial implementation (not usable yet)
35 - added support for v2 multiple stage envelope generators
36 - added a fine-tuned v1 envelope generator instead of using the
37 one from the gig engine
38 - fixed memory leak and memory handling errors
39 - added support for trigger=first, trigger=legato and sw_previous
40 - allow non-numerical key values ("C#4" for example)
41 - "key" opcode now sets pitch_keycenter too

72 * Host plugins:
73 - AU bugfix: failed to destroy its audio/MIDI devices
74 - Listen to all interfaces on Mac OS X (INADDR_ANY)
75 - VST bugfix: If the host called resume() before and after
76 changing sample rate or block size, the number of channels was
77 incorrectly set to two. This caused silence in Cubase 5.
79 * MIDI driver:
80 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
81 the ALSA sequencer client name

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