* bumped version to 1.0.0.cvs7

1 Version CVS HEAD (?)
2
3 * packaging changes:
4 - fixed building with newer MinGW-w64
5
6 * general changes:
7 - Refactoring: moved the independent code from
8 the Gigasampler format engine to base classes
9 - command line option '--profile' is currently disabled, since the
10 respective profiling code is currently broken
11 - Introduced support for optional environment variable
12 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
13 where the sampler shall look for instrument editor plugins
14 (patch by Luis Garrido, slightly modified).
15 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
16 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
17 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
18 note (in this implementation of the sampler its simply hard routed to
19 the 1st effect send of the sampler channel, no matter what the actual
20 effect type is)
21 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
22 note (in this implementation of the sampler its simply hard routed to
23 the 2nd effect send of the sampler channel, no matter what the actual
24 effect type is)
25 - implemented support for internal LADSPA effects
26
27 * Gigasampler format engine:
28 - implemented the "round robin keyboard" dimension
29 - fixed round robin and random dimensions for cases when number of
30 dimension zones is not a power of two
31 - made round robin use a counter for each region instead of each
32 key
33
34 * SFZ format engine:
35 - Initial implementation (not usable yet)
36 - added support for v2 multiple stage envelope generators
37 - added a fine-tuned v1 envelope generator instead of using the
38 one from the gig engine
39 - fixed memory leak and memory handling errors
40 - added support for trigger=first, trigger=legato and sw_previous
41 - allow non-numerical key values ("C#4" for example)

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

122
123 Version 1.0.0 (31 July 2009)
124
125 * packaging changes:
126 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
127 causing e.g. the libgig test to fail when
128 "./configure --disable-jack-driver" was used
129 (patch by Alexis Ballier)
130 - fixed compilation with gcc 4.3
131 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
132 - fixed configure so it detects x86_64 (#107)
133 - fixes for building with newer MinGW versions
134 - fix for building with bison 2.4 (#111)
135 - fixed building with libgig installed in a non-standard directory
136 - minor fix in configure for mmsystem.h detection on MinGW
137 - Windows: look for editor plugins and Fantasia using base
138 directory of liblinuxsampler dll (look in the same directory and one
139 directory above)
140 - configure script fix: removed unconditional use of SSE
141 - fixed building with sqlite installed in a non-standard directory
142 - when cross-compiling, don't try to create instruments.db
143 - fix for new mingw-w64 version, which has usleep
144
145 * general changes:
146 - bugfix: on some POSIX systems instrument editor plugins refused to
147 load as we used a non-portable Linux specific struct field
148 (fixes bug #70, patch by Ronald Baljeu)
149 - fixed endless loop which occured when loading an instrument editor
150 plugin DLL on Windows systems failed
151 - fixed memory leaks that occurred when liblinuxsampler was unloaded
152 - optimized the SynchronizedConfig class so it doesn't wait
153 unnecessarily long after an update
154 - added support for notifying instrument editors on note-on / note-off
155 events (e.g. to highlight the pressed keys on the virtual keyboard
156 of gigedit)
157 - added support for triggering notes by instrument editors (see above)
158 - be verbose on DLL load errors (on Linux)
159 - fixed di-harmonic triangle LFO implementation (this LFO implementation
160 is only used by very few systems, most pick the int math
161 implementation, which is usually faster)
162 - fixes for audio drivers with varying buffer sizes
163 - experimental support for running LinuxSampler as a DSSI, LV2 and
164 VST plugin
165 - notification events for stream/voice count statistics are now sent
166 only when there are actual changes
167 - added memory ordering constraints to improve stability on
168 multi-core and multi-cpu systems
169 - maximum voices and disk streams can now be altered at runtime
170 - fixed CPU feature detection on x86_64 (maybe fixes #108)
171 - automatic stacktrace mechanism is now turned off by default and can
172 be switched on by command line option "--stacktrace" (the automatic
173 stacktrace mechanism seems to be broken on most systems at the moment)
174 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
175 a pointer to the launched InstrumentEditor object
176 - added optional 3rd party user data parameter for following
177 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
178 InstrumentEditor::Launch(),
179 InstrumentManager::LaunchInstrumentEditor()
180 - theoretical fix: made SynchronizedConfig follow C++0x memory
181 model more strictly
182 - fixes for using large audio device buffers
183 - Windows: add the installation directory to the DLL search path
184 when loading an editor plugin (solves problems with VST and
185 gigedit on systems with other GTK versions installed)
186
187 * audio driver:
188 - removed the nonsense audio channel constraint (which was hard coded to
189 max. 100 audio channels) for most audio drivers
190 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
191 opposed to the LSCP specs
192 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
193 reflected the wrong value
194 - fixed a memory management bug in ASIO driver
195 - Makefile fix: JACK_CFLAGS wasn't used
196 - JACK: use jack_client_open instead of the deprecated
197 jack_client_new
198 - added (experimental) CoreAudio driver
199 - applied old fixes to the ASIO driver that were included in the
200 previous binary release but accidentally never committed to CVS
201 (fixes #117)
202 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
203 win64)
204 - VST: added support for sample rate and buffer size changes
205 - VST: close editor (Fantasia) when the VST is removed
206 - VST: avoid opening Fantasia more than once for each VST instance
207 - VST: export main function as "main" on Linux too (fix for
208 energyXT)
209 - VST: changed number of output channels from one stereo to 16
210 stereo
211 - added channel routing, fxsends and midi maps to the settings
212 stored in the plugin state
213 - performance optimization of AudioChannel::MixTo() and
214 AudioChannel::CopyTo() methods using GCC vector exensions
215 (if available)
216 - ASIO fixes: avoid initializing the device twice, avoid throwing
217 exception when getting parameters from a disconnected device
218
219 * MIDI driver:
220 - added JACK MIDI driver
221 - dispatch bank select as ordinary CC as well, the user might seriously
222 want to (mis)use it for some purpose ("fixed" in all current MIDI
223 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
224 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
225 CoreMidi or AU
226 - fixed mingw-w64 compilation error in MME driver
227 - made program change handling in MIDI thread real-time safe by
228 moving the logic to a non-RT thread
229 - fixed minor memory leak in ALSA driver
230
231 * instruments database:
232 - avoid time consuming samples scanning when adding instruments
233 to the instruments database
234 - added support for handling lost files in the instruments database
235 - Implemented option for adding instruments in separate directories
236 in the instruments database
237 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
238 - work-around for missing fnmatch function on Windows to make
239 instrument database compilable
240 - added instrument database support on Windows
241 works with both standalone mode and VST plugin.
242 the instruments DB file is located in
243 %USERPROFILE%\.linuxsampler\instruments.db which allows different
244 databases for each windows user
245 if no DB is present it automatically creates the .linuxsampler subdir
246 and then creates an empty DB
247 - fixed recursive import, which was broken on Windows
248
249 * Gigasampler format engine:
250 - fixed a memory leak that could happen when a channel was deleted
251 while notes were playing
252 - made it possible to load an instrument even if the audio thread
253 isn't running
254 - added partial support for the "Controller Triggered" MIDI rule,
255 enough for piano gigs with pedal noise samples
256 - minor fix: only mark FX sends as being modified if really the
257 respective FX send MIDI controller was used
258 - added support for GM global device volume SysEx message
259 (can be selected at compile time to either apply globally to the
260 whole sampler [default] or only to the sampler channels that are
261 connected to the respective MIDI input port the SysEx message arrived
262 on)
263 - bugfix: notes triggered at position 0 in the audio buffer were
264 sometimes wrongly killed in the same buffer, causing no sound to
265 be played
266 - added support for chromatic / drumkit mode Roland GS Sysex message
267 which is usally used to switch a part between chromatic sounds and
268 drumkit sounds (as opposed to their common default setting of MIDI
269 part 10 being a drumkit part and all other ones chromatic parts), in
270 LS however one can switch between the first 16 MIDI instrument maps
271 defined for the sampler
272 - made it possible to create multiple sample channels even if the
273 audio thread isn't running
274 - fixed crash when removing channel with active voices (#116)
275 - bugfix: on sample reference changes (instrument editor), only
276 un-cache the respective sample if it's really not used by any
277 sampler engine anymore
278 - re-cache samples in case they were changed by an instrument editor,
279 e.g. when a sample was added while playing (#82)
280 - fixed hanging notes which occured when note-off event had the exact
281 same time stamp as the voice's note-on event and occured both in the
282 same audio fragment cycle (fixes bug #112)
283 - added support for the "fine tune" and "pitch bend range"
284 instrument-level gig parameters
285 - fixed minor artifacts in pitch bend handling
286 - added support for GS Reset SysEx message
287 - allow gig files to use unlimited downward pitch shifting
288 - added a limit check for upward pitch shifting
289 - bugfix: sometimes, when playing a note twice fast, the second
290 note was silent
291 - fixed crash happening when a pitch bend event arrived at the
292 same time a new instrument was loading
293
294 * LSCP server:
295 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
296 react on MIDI data arriving on certain sampler channels (so far only
297 Note-On and Note-Off events are sent via this LSCP event)
298 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
299 react on MIDI data arriving on certain MIDI input devices (so far only
300 Note-On and Note-Off events are sent via this LSCP event)
301 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
302 SET DB_INSTRUMENT FILE_PATH
303 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
304 frontends to send MIDI messages to specific sampler channel
305 - added two additional fields to GET FILE INSTRUMENT INFO command -
306 KEY_BINDINGS and KEYSWITCH_BINDINGS
307 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
308 was incorrect
309 - Optimized the retrieval of the MIDI instrument mappings
310 - added new LSCP command "SET VOICES" to globally alter the maximum
311 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
312 be triggered respectively
313 - added new LSCP command "SET STREAMS" to globally alter the maximum
314 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
315 which will be triggered respectively
316 - bugfix: retry if "select" returns EINTR (this fixes a crash when
317 a gigedit file dialog is opened)
318 - close all connections when LSCPServer is deleted
319 - hard close of all sockets on exit
320 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
321 driver
322
323 * Bug fixes:
324 - fixed a crash which occurs when removing a sampler channel waiting
325 to start instrument loading after another channel
326 - fixed a crash which occurs when removing a sampler channel with
327 instrument loading in progress (bug #113)
328 - fixed termination caused by uncaught exception when adding MIDI
329 instrument with PERSISTENT load mode
330 - fixed possible iterator invalidations when resetting the sampler
331 - fixed memory leaks when issuing the following LSCP commands:
332 GET AUDIO_OUTPUT_DRIVER INFO
333 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
334 GET MIDI_INPUT_DRIVER INFO
335 GET MIDI_INPUT_DRIVER_PARAMETER INFO
336 - fixed possible compilation error when sqlite is not present
337 - fixed orphaned pointers when setting maximum voices limit (bug #118)
338 - fixed crash when changing the audio output device of a sampler
339 channel with loaded instrument and start playing notes
340 - fixed endless loop in Engine::SuspendAll() (bug #120)
341 - fixed a low-level atomic load function that was broken on 64-bit
342 PowerPC, which probably could cause crashes on that platform
343 - fixed a memory management error which could cause a crash when a
344 plugin was unloaded
345 - bugfix: two private structs had the same name, which could cause
346 problems if the linker chose the wrong constructor
347 - fixed low-level ConditionServer usage bug that caused lockups on
348 Windows
349
350
351 Version 0.5.1 (6 December 2007)
352
353 * packaging changes:
354 - added autoconf checks for pthread library
355 - added autoconf check for pthread bug found on certain NPTL-enabled
356 glibc versions (see Gentoo bug report #194076)
357 - added autoconf checks for MS Windows
358
359 * general changes:
360 - bugfix: the thread used by an editor plugin didn't die when the
361 editor closed
362 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
363 out all the space. operator--() did not apply size_mask after
364 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
365 order to avoid problems with the _NonVolatileReader functions.
366 - bugfix: Stream.h: added a missing divide by BytesPerSample in
367 GetWriteSpace(). Since this function is currently only used in
368 the stream's qsort() compare function, it didn't trigger any
369 bugs.
370 - Resampler.h, Synthesizer.h: cubic interpolation now works in
371 24bit mode too. Faster method to read 24bit words on little
372 endian machines (x86): replaced 3 byte reads + shifts with a 1
373 unaligned 32bit read and shift
374 - experimental support for MS Windows (MIDI input via MME, AUDIO
375 output via ASIO)
376 - made handling of SIGINT signal (Ctrl-C) a bit more robust
377 - support for monitoring the total number of active disk streams
378 (new LSCP commands: GET TOTAL_STREAM_COUNT,
379 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
380
381 * AUDIO driver:
382 - added Windows ASIO low latency audio driver
383
384 * MIDI driver:
385 - added MME Windows MIDI driver
386
387 * LSCP server:
388 - added support for Windows style path / filenames, however with
389 forward slash path separators instead of backslash
390 (i.e. "C:/foo/bar.gig")
391 - allow naughty liblscp to send non-string device parameters within
392 apostrophes as well
393 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
394 "LIST FILE INSTRUMENTS <file>" and
395 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
396 about an arbitrary instrument file on the system where the sampler is
397 running on
398
399 Version 0.5.0 (15 October 2007)
400
401 * packaging changes:
402 - config.h is not going to be installed along with liblinuxsampler's
403 API header files anymore
404 - only the API relevant header (and source) files will be exported to
405 the Doxygen API documentation (explicitly listed in Doxyfile.in)
406 - added completely new XCode project files for Mac OSX which is now
407 capable to execute our autoconf environment, thus no need anymore
408 to maintain the compile time configuration file (osx/version.h) for
409 OSX manually (patch by Toshi Nagata)
410 - fixed buggy boolean --enable-foo / --disable-foo configure script
411 parameters
412 - global.h now only covers global definitions that are needed for the
413 C++ API header files, all implementation internal global definitions
414 are now in global_private.h
415 - atomic.h is not exposed to the C++ API anymore
416 - no need to include config.h anymore for using LS's API header files
417 - fixed warnings in API doc generation
418
419 * general changes:
420 - replaced the old, confusing MIDI program change mechanism by a
421 flexible MIDI instrument mapper which allows to map arbitrary
422 (MIDI bank, MIDI program) pairs with arbitrary
423 (engine type, instrument file, file index) triplets which will be
424 loaded on the respective channel when such MIDI program change
425 messages arrive, beside that, each entry allows to define a life-time
426 strategy for the instrument, so the user can define whether the
427 instrument should i.e. be permanently loaded (to be able to switch
428 quickly among sounds) or i.e. loaded just on demand when the
429 respective program change arrives (to safe RAM space), as well as a
430 global volume factor for each entry, so the user can adjust the volume
431 dynamic of his mapped instrument collection without having to modify
432 the instrument files, also one can manage arbitrary amount of such
433 MIDI instrument maps and assign each sampler channel individually
434 a certain map, so that i.e. separation of normal instruments and
435 drumkits is possible
436 - new notification events for tracking changes to audio/MIDI devices,
437 MIDI instrument maps, MIDI instruments, FX sends, global volume.
438 - sampler was limited to load max. 200 instruments in the background
439 due to a constant size RingBuffer FIFO which is now replaced by a
440 dynamic (unlimited) size std::list FIFO
441 - added FX sends, these allow to route audio signals to arbitrary audio
442 output channels for being processed by external effect processors
443 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
444 controllers
445 - global (sampler wide) volume can now be controlled at runtime
446 - Implemented new, improved notification system
447 - fixed compilation errors regarding OSX
448 (patch by Toshi Nagata)
449 - implemented instruments database
450 - added support for escape sequences to the instruments database
451 - added highly experimental support for on-the-fly instrument editing
452 within the sampler's process (by using instrument editor plugins),
453 you'll notice the new "Registered instrument editors:" message on
454 startup, added a new LSCP command:
455 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
456 to spawn a matching instrument editor for the instrument on the
457 given sampler channel, the plugin path can be overridden at compile
458 time with ./configure --enable-plugin-dir=/some/dir
459 - added experimental code for synchronizing instrument editors hosted
460 in the sampler's process to safely edit instruments while playing
461 without a crash (hopefully) by either suspending single regions
462 wherever possible or if unavoidable whole engine(s)
463 - fixed several issues in fundamental "Thread" class: set scheduling
464 policy and priority on thread level, set a minimum stack size for
465 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
466 threads simply inherited properties of starting thread instead of
467 setting their own policy and priority
468 - minor fix in our automatic stack trace mechanism on crashes, the
469 main process did not wait for the stack trace process to finish
470 its output
471 - fixed some minor memory leaks
472 - reenabled assembly features support, at the moment only for
473 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
474 - minor assembly fix in x86 features detection (don't use the PIC
475 register, to avoid relocations in the text segment at runtime)
476 - POSIX callback functions of Thread.h are hidden
477
478 * MIDI driver:
479 - dispatch bank select (MSB and LSB) messages
480
481 * audio driver:
482 - the ALSA audio output driver parameters now reflect the correct
483 parameter value ranges for the respective selected sound card
484 (patch by Till Wimmer, a bit fixed and extended)
485
486 * Gigasampler format engine:
487 - if a filter is used and EG2 finishes before EG1, let the voice
488 die when EG2 has finished (this fixes a problem with clicks and
489 voice starvation for some gigs)
490 - playback is no longer disabled during instrument loading
491 - all notes playing on a channel that changes its instrument keep
492 playing with the old instrument until they get a note off
493 command
494 - EG fix: a release value of zero could cause noises or crash
495 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
496 - EG fine tuning: when attack is zero the EG starts at a level
497 above max sustain level, which means that there is a decay phase
498 even if sustain is 100%
499 - more EG fixes: the level could sometimes go below zero and cause
500 noises or crashes
501 - minor fix of EGDecay (patch by Toshi Nagata)
502 - fixed compiler error when --enable-override-filter-type was
503 supplied to the configure script (fixes #46)
504 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
505 instead of a fix value
506 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
507 127 (solo mode) only kill voices if the respective mode really
508 changed
509
510 * LSCP server:
511 - fixed compile time error for old Bison versions
512 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
513 - parser now supports extended ASCII character set
514 (up to ASCII code 255, i.e. includes now umlauts and accents)
515 - filename arguments in LSCP commands now allow to use escape
516 sequences, that is directly literal as one of: \', \", \\, \n, \r,
517 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
518 code value like \xf2) (fixes bug #24)
519 - the following LSCP commands now also support escape sequences for at
520 least one of their text-based parameters (i.e. name, description):
521 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
522 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
523 "SET DB_INSTRUMENT_DIRECTORY NAME",
524 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
525 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
526 "FIND DB_INSTRUMENT_DIRECTORIES"
527 - returns verbose syntax errors (line and column where syntax error
528 occured, the unexpected character and the actually expected, possible
529 character(s), the latter only if less than 5 possibilities)
530 - made sure that LSCP syntax is not affected by gigedit locale
531 settings
532 - bugfix regarding strings parameter lists: all comma separated lists
533 of strings were treated as being one string containing commas
534 (fixes #57)
535
536 * Bug fixes:
537 - fixed crash occurring on certain LSCP scripts (Bug 39)
538 - another thread safety fix for lscp "load engine" and "set
539 channel audio output device"
540 - fixed a crash which occurs when reassigning the same engine
541 on a sampler channel with connected MIDI device
542 - fixed a crash which occurs when changing the number of ports of a MIDI
543 device connected to a sampler channel to number less then or equal
544 to the index of the port to which the sampler channel is connected.
545 - The previous bindings were not been disconnected when altering
546 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
547 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
548 - The active stream/voice count statistic was incorrect.
549 - notification events were not been sent for some sampler
550 channel changes
551 - added default min and max values to restrict the number of allowed
552 audio output channels and MIDI input ports
553 - the connection to the PCM interface is now closed when destroying
554 an audio output device
555 - files with slash in their path or filename could not be loaded
556
557 * test cases:
558 - updated and fixed (haven't been touched in a while)
559
560 Version 0.4.0 (24 November 2006)
561
562 * packaging changes:
563 - changed deprecated copyright attribute to license; added ldconfig
564 to post-(un)install steps; added devel package for liblinuxsampler;
565 to linuxsampler.spec (RPM)
566 - install necessary development header files for allowing 3rd party
567 applications to link against liblinuxsampler
568 - liblinuxsampler's API documentation can be generated with 'make docs'
569 (Doxygen required)
570 - added benchmark to automatically detect the best triangle LFO
571 implementation (currently either an integer math solution or a
572 di-harmonic approximation), automatic detection can be overriden
573 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
574 configure script argument though (mandatory for cross-compilation)
575 - do not automatically pick optimized gcc flags if the user already
576 provided some on his own (as CXXFLAGS)
577 - added compile time option to disable processing of All-Notes-Off MIDI
578 messages
579 - added compile time options to allow disabling the various audio and
580 MIDI drivers
581 - fixed automatic GCC CPU switch detection on PPC
582 (patch by Ebrahim Mayat)
583
584 * Gigasampler format engine:
585 - extensive synthesis optimization
586 (reimplementation of EGs and LFO(s), removed synthesis parameter
587 prerendering and the synthesis parameter matrix in general, splitting
588 each audio fragment into subfragments now where each subfragment uses
589 constant pitch and filter coefficients. The volume coefficient is
590 linearly interpolated inside a subfragment, unless
591 --disable-interpolate-volume is set.)
592 - fine tuning of the EG modulation parameters
593 - improved filter cutoff calculation by adding support for the
594 following gig parameters: Cutoff freq (used when no cutoff
595 controller is defined), Control invert, Minimum cutoff, Velocity
596 curve and Velocity range. The keyboard tracking now scales
597 cutoff frequency instead of resonance.
598 - added support for gig parameter Resonance.
599 - fixed bug in sysex handling (patch by Juan Linietsky)
600 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
601 which can be overridden with --enable-global-attenuation
602 - EG fixes: made the length of "attack hold" stage more
603 accurate. Release stage can now start before attack stage
604 ends. Cancel release didn't work when sustain was zero. Attack
605 time now has a minimal value to prevent clicks.
606 - fixed pitch changes larger than one octave
607 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
608 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
609 all modes can be altered via standard GM messages, that is CC5 for
610 altering portamento time, CC65 for enabling / disabling portamento
611 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
612 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
613 parameter) and crossfade
614 - added support for the "attenuation controller threshold" gig
615 parameter
616 - added smoothing of volume changes caused by control change
617 messages
618 - sample loop parameters are now taken from the DimensionRegion
619 instead of the wave chunk
620 - fixed keyswitching for v3 gigs with a number of keyswitch splits
621 not equal to a power of two
622 - reimplementation of the filter algorithm. The new filter is more
623 accurate and supports all gig filter types, including bandreject
624 and lowpass turbo.
625 - real support for 24 bit samples - samples are not truncated to
626 16 bits anymore
627 - support for aftertouch (channel pressure, not polyphonic
628 aftertouch)
629 - LFO1 behaviour fixed (dampening from max volume instead of
630 amplifying from 0)
631
632 * LSCP server:
633 - fixed application exit on broken pipe error (fixes bug #20)
634 - fixed the notification messages delay due to lack of
635 network activity (fixes bug #26)
636 - fixed parser bug which occured on space(s) within device parameters
637 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
638
639 * audio driver:
640 - added aRts audio output driver (by no means RT safe)
641
642 * MIDI driver:
643 - fixed legacy sysex code which caused dispatching of MIDI SysEx
644 messages several times instead of once
645 - API extension for MIDI drivers which already supply exact time stamps
646 for events (i.e. for offline rendering based MIDI drivers)
647 - added checks for bad MIDI data
648
649 * linuxsampler application:
650 - show available sampler engine types on startup
651
652 * general changes:
653 - support for muting sampler channels and solo mode of the same, two new
654 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
655 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
656 introduced for this, the behavior is the same like on a mixer console
657 (patch by Grigor Iliev, a bit adjusted). Also added configure option
658 --enable-process-muted-channels which can be used to enable the
659 processing of muted channels.
660 - support for sostenuto pedal
661 - support for monitoring the total number of active voices
662 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
663 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
664 - fixed some memory management errors
665 - fixed some concurrency problems that could lead to crashes when
666 LSCP commands were executed
667 - fixed crash when instrument loading failed previously on the same
668 sampler channel (fixes bug #36)
669
670 Version 0.3.3 (15 July 2005)
671
672 * packaging changes:
673 - fixed compilation with gcc 4.0
674
675 * Gigasampler format engine:
676 - LFO preprocessing was performed even though the respective LFO was
677 disabled by the instrument patch (minor efficiency fix)
678 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
679 for volume ramp downs in the same fragment (needed for current voice
680 stealing implementation) then simply inform the user with a warning
681 about possible click sounds and reduce the volume ramp down
682 appropriately instead of cancelling the audio device connection
683
684 Version 0.3.2 (24 June 2005)
685
686 * packaging changes:
687 - updated autotools build files to compile on OS X
688 (conditional compilation of CoreMIDI and MidiShare drivers)
689 - hand-crafted assembly optimization code can be disabled with
690 './configure --disable-asm' (definitely not recommended)
691 - fixed 'make dist' rule to include all necessary files
692 - require automake (>= 1.5) for 'make -f Makefile.cvs'
693 (due to 'dist-bzip2' automake option)
694
695 * Gigasampler format engine:
696 - support for the gig parameters for "release velocity response" curves
697 - fine tuning of the EGADSR envelope
698 - volume of release triggered samples now depends on note-on velocity,
699 note length and gig parameter "release trigger decay" instead of
700 note-off velocity.
701 - revised voice stealing
702 (fixes crash and endless loop caused by voice stealing)
703 - don't reset scale tuning on instrument or audio output device change
704 - handle key group conflicts right at the beginning of each fragment
705 instead of when the respective voice is actually launched
706 (fixes undefined behavior if stolen voices belonged to a key group -
707 this case was followed by a "killed voice survived" error message)
708 - fixed minor issue with null/silence samples
709 (those stole voices even though they don't need a voice at all which
710 resulted in "voice stealing didn't work out" messages)
711 - don't reset volume, pan, pitch and MIDI controller values on
712 instrument or audio output device change
713
714 * LSCP server:
715 - fixed some crashes (patch by Grigor Iliev, fixes #19)
716 - fixed LSCP event "CHANNEL_INFO" notification
717 (e.g. did not notify on volume changes or MIDI program change events)
718
719 * linuxsampler application:
720 - added command line parameters --lscp-addr and --lscp-port to override
721 default IP address and port of LSCP server
722
723 Version 0.3.1 (24 May 2005)
724
725 * initial release
