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
16 * Gigasampler format engine:
17 - implemented the "round robin keyboard" dimension
18 - fixed round robin and random dimensions for cases when number of
19 dimension zones is not a power of two
20 - made round robin use a counter for each region instead of each
21 key
22
23 * SFZ format engine:
24 - Initial implementation (not usable yet)
25 - added support for v2 multiple stage envelope generators
26 - added a fine-tuned v1 envelope generator instead of using the
27 one from the gig engine
28 - fixed memory leak and memory handling errors
29 - added support for trigger=first, trigger=legato and sw_previous
30 - allow non-numerical key values ("C#4" for example)
31 - "key" opcode now sets pitch_keycenter too
32 - fixed error when unloading instrument with same sample used by
33 multiple regions
34 - added some opcode aliases, like loopmode for loop_mode, to be
35 more compatible
36 - added support for trigger=release and rt_decay
37 - added support for off_mode=normal
38 - added support for random, seq_position, seq_length and volume

61
62 * Host plugins:
63 - AU bugfix: failed to destroy its audio/MIDI devices
64 - Listen to all interfaces on Mac OS X (INADDR_ANY)
65 - VST bugfix: If the host called resume() before and after
66 changing sample rate or block size, the number of channels was
67 incorrectly set to two. This caused silence in Cubase 5.
68

80
81 Version 1.0.0 (31 July 2009)
82
83 * packaging changes:
84 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
85 causing e.g. the libgig test to fail when
86 "./configure --disable-jack-driver" was used
87 (patch by Alexis Ballier)
88 - fixed compilation with gcc 4.3
89 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)

91 - fixes for building with newer MinGW versions
92 - fix for building with bison 2.4 (#111)
93 - fixed building with libgig installed in a non-standard directory
94 - minor fix in configure for mmsystem.h detection on MinGW
95 - Windows: look for editor plugins and Fantasia using base
96 directory of liblinuxsampler dll (look in the same directory and one
97 directory above)

99 - fixed building with sqlite installed in a non-standard directory
100 - when cross-compiling, don't try to create instruments.db
101 - fix for new mingw-w64 version, which has usleep
102
103 * general changes:
104 - bugfix: on some POSIX systems instrument editor plugins refused to
105 load as we used a non-portable Linux specific struct field
106 (fixes bug #70, patch by Ronald Baljeu)
107 - fixed endless loop which occured when loading an instrument editor
108 plugin DLL on Windows systems failed
109 - fixed memory leaks that occurred when liblinuxsampler was unloaded
110 - optimized the SynchronizedConfig class so it doesn't wait
111 unnecessarily long after an update
112 - added support for notifying instrument editors on note-on / note-off
113 events (e.g. to highlight the pressed keys on the virtual keyboard
114 of gigedit)
115 - added support for triggering notes by instrument editors (see above)
116 - be verbose on DLL load errors (on Linux)
117 - fixed di-harmonic triangle LFO implementation (this LFO implementation
118 is only used by very few systems, most pick the int math
119 implementation, which is usually faster)
120 - fixes for audio drivers with varying buffer sizes
121 - experimental support for running LinuxSampler as a DSSI, LV2 and
122 VST plugin
123 - notification events for stream/voice count statistics are now sent
124 only when there are actual changes
125 - added memory ordering constraints to improve stability on
126 multi-core and multi-cpu systems
127 - maximum voices and disk streams can now be altered at runtime
128 - fixed CPU feature detection on x86_64 (maybe fixes #108)
129 - automatic stacktrace mechanism is now turned off by default and can
130 be switched on by command line option "--stacktrace" (the automatic
131 stacktrace mechanism seems to be broken on most systems at the moment)
132 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
133 a pointer to the launched InstrumentEditor object
134 - added optional 3rd party user data parameter for following
135 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
136 InstrumentEditor::Launch(),
137 InstrumentManager::LaunchInstrumentEditor()
138 - theoretical fix: made SynchronizedConfig follow C++0x memory
139 model more strictly
140 - fixes for using large audio device buffers
141 - Windows: add the installation directory to the DLL search path
142 when loading an editor plugin (solves problems with VST and
143 gigedit on systems with other GTK versions installed)
144
145 * audio driver:
146 - removed the nonsense audio channel constraint (which was hard coded to
147 max. 100 audio channels) for most audio drivers
148 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
149 opposed to the LSCP specs
150 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
151 reflected the wrong value
152 - fixed a memory management bug in ASIO driver
153 - Makefile fix: JACK_CFLAGS wasn't used
154 - JACK: use jack_client_open instead of the deprecated
155 jack_client_new
156 - added (experimental) CoreAudio driver
157 - applied old fixes to the ASIO driver that were included in the
158 previous binary release but accidentally never committed to CVS
159 (fixes #117)
160 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
161 win64)
162 - VST: added support for sample rate and buffer size changes
163 - VST: close editor (Fantasia) when the VST is removed
164 - VST: avoid opening Fantasia more than once for each VST instance
165 - VST: export main function as "main" on Linux too (fix for
166 energyXT)
167 - VST: changed number of output channels from one stereo to 16
168 stereo
169 - added channel routing, fxsends and midi maps to the settings
170 stored in the plugin state
171 - performance optimization of AudioChannel::MixTo() and
172 AudioChannel::CopyTo() methods using GCC vector exensions
173 (if available)
174 - ASIO fixes: avoid initializing the device twice, avoid throwing
175 exception when getting parameters from a disconnected device
176
177 * MIDI driver:
178 - added JACK MIDI driver
179 - dispatch bank select as ordinary CC as well, the user might seriously
180 want to (mis)use it for some purpose ("fixed" in all current MIDI
181 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
182 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
183 CoreMidi or AU
184 - fixed mingw-w64 compilation error in MME driver
185 - made program change handling in MIDI thread real-time safe by
186 moving the logic to a non-RT thread
187 - fixed minor memory leak in ALSA driver
188
189 * instruments database:
190 - avoid time consuming samples scanning when adding instruments
191 to the instruments database
192 - added support for handling lost files in the instruments database
193 - Implemented option for adding instruments in separate directories
194 in the instruments database
195 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
196 - work-around for missing fnmatch function on Windows to make
197 instrument database compilable
198 - added instrument database support on Windows
199 works with both standalone mode and VST plugin.
200 the instruments DB file is located in
201 %USERPROFILE%\.linuxsampler\instruments.db which allows different
202 databases for each windows user
203 if no DB is present it automatically creates the .linuxsampler subdir
204 and then creates an empty DB
205 - fixed recursive import, which was broken on Windows
206
207 * Gigasampler format engine:
208 - fixed a memory leak that could happen when a channel was deleted
209 while notes were playing
210 - made it possible to load an instrument even if the audio thread
211 isn't running
212 - added partial support for the "Controller Triggered" MIDI rule,
213 enough for piano gigs with pedal noise samples
214 - minor fix: only mark FX sends as being modified if really the
215 respective FX send MIDI controller was used
216 - added support for GM global device volume SysEx message
217 (can be selected at compile time to either apply globally to the
218 whole sampler [default] or only to the sampler channels that are
219 connected to the respective MIDI input port the SysEx message arrived
220 on)
221 - bugfix: notes triggered at position 0 in the audio buffer were
222 sometimes wrongly killed in the same buffer, causing no sound to
223 be played
224 - added support for chromatic / drumkit mode Roland GS Sysex message
225 which is usally used to switch a part between chromatic sounds and
226 drumkit sounds (as opposed to their common default setting of MIDI
227 part 10 being a drumkit part and all other ones chromatic parts), in
228 LS however one can switch between the first 16 MIDI instrument maps
229 defined for the sampler
230 - made it possible to create multiple sample channels even if the
231 audio thread isn't running
232 - fixed crash when removing channel with active voices (#116)
233 - bugfix: on sample reference changes (instrument editor), only
234 un-cache the respective sample if it's really not used by any
235 sampler engine anymore
236 - re-cache samples in case they were changed by an instrument editor,
237 e.g. when a sample was added while playing (#82)
238 - fixed hanging notes which occured when note-off event had the exact
239 same time stamp as the voice's note-on event and occured both in the
240 same audio fragment cycle (fixes bug #112)
241 - added support for the "fine tune" and "pitch bend range"
242 instrument-level gig parameters
243 - fixed minor artifacts in pitch bend handling
244 - added support for GS Reset SysEx message
245 - allow gig files to use unlimited downward pitch shifting
246 - added a limit check for upward pitch shifting
247 - bugfix: sometimes, when playing a note twice fast, the second
248 note was silent
249 - fixed crash happening when a pitch bend event arrived at the
250 same time a new instrument was loading
251
252 * LSCP server:
253 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
254 react on MIDI data arriving on certain sampler channels (so far only
255 Note-On and Note-Off events are sent via this LSCP event)
256 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
257 react on MIDI data arriving on certain MIDI input devices (so far only
258 Note-On and Note-Off events are sent via this LSCP event)
259 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
260 SET DB_INSTRUMENT FILE_PATH
261 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
262 frontends to send MIDI messages to specific sampler channel
263 - added two additional fields to GET FILE INSTRUMENT INFO command -
264 KEY_BINDINGS and KEYSWITCH_BINDINGS
265 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
266 was incorrect
267 - Optimized the retrieval of the MIDI instrument mappings
268 - added new LSCP command "SET VOICES" to globally alter the maximum
269 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
270 be triggered respectively
271 - added new LSCP command "SET STREAMS" to globally alter the maximum
272 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
273 which will be triggered respectively
274 - bugfix: retry if "select" returns EINTR (this fixes a crash when
275 a gigedit file dialog is opened)
276 - close all connections when LSCPServer is deleted
277 - hard close of all sockets on exit
278 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
279 driver
280
281 * Bug fixes:
282 - fixed a crash which occurs when removing a sampler channel waiting
283 to start instrument loading after another channel
284 - fixed a crash which occurs when removing a sampler channel with
285 instrument loading in progress (bug #113)
286 - fixed termination caused by uncaught exception when adding MIDI
287 instrument with PERSISTENT load mode
288 - fixed possible iterator invalidations when resetting the sampler
289 - fixed memory leaks when issuing the following LSCP commands:
290 GET AUDIO_OUTPUT_DRIVER INFO
291 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
292 GET MIDI_INPUT_DRIVER INFO
293 GET MIDI_INPUT_DRIVER_PARAMETER INFO
294 - fixed possible compilation error when sqlite is not present
295 - fixed orphaned pointers when setting maximum voices limit (bug #118)
296 - fixed crash when changing the audio output device of a sampler
297 channel with loaded instrument and start playing notes
298 - fixed endless loop in Engine::SuspendAll() (bug #120)
299 - fixed a low-level atomic load function that was broken on 64-bit
300 PowerPC, which probably could cause crashes on that platform
301 - fixed a memory management error which could cause a crash when a
302 plugin was unloaded
303 - bugfix: two private structs had the same name, which could cause
304 problems if the linker chose the wrong constructor
305 - fixed low-level ConditionServer usage bug that caused lockups on
306 Windows
307
308
309 Version 0.5.1 (6 December 2007)
310
311 * packaging changes:
312 - added autoconf checks for pthread library
313 - added autoconf check for pthread bug found on certain NPTL-enabled
314 glibc versions (see Gentoo bug report #194076)
315 - added autoconf checks for MS Windows
316
317 * general changes:
318 - bugfix: the thread used by an editor plugin didn't die when the
319 editor closed
320 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
321 out all the space. operator--() did not apply size_mask after
322 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
323 order to avoid problems with the _NonVolatileReader functions.
324 - bugfix: Stream.h: added a missing divide by BytesPerSample in
325 GetWriteSpace(). Since this function is currently only used in
326 the stream's qsort() compare function, it didn't trigger any
327 bugs.
328 - Resampler.h, Synthesizer.h: cubic interpolation now works in
329 24bit mode too. Faster method to read 24bit words on little
330 endian machines (x86): replaced 3 byte reads + shifts with a 1
331 unaligned 32bit read and shift
332 - experimental support for MS Windows (MIDI input via MME, AUDIO
333 output via ASIO)
334 - made handling of SIGINT signal (Ctrl-C) a bit more robust
335 - support for monitoring the total number of active disk streams
336 (new LSCP commands: GET TOTAL_STREAM_COUNT,
337 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
338
339 * AUDIO driver:
340 - added Windows ASIO low latency audio driver
341
342 * MIDI driver:
343 - added MME Windows MIDI driver
344
345 * LSCP server:
346 - added support for Windows style path / filenames, however with
347 forward slash path separators instead of backslash
348 (i.e. "C:/foo/bar.gig")
349 - allow naughty liblscp to send non-string device parameters within
350 apostrophes as well
351 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
352 "LIST FILE INSTRUMENTS <file>" and
353 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
354 about an arbitrary instrument file on the system where the sampler is
355 running on
356
357 Version 0.5.0 (15 October 2007)
358
359 * packaging changes:
360 - config.h is not going to be installed along with liblinuxsampler's
361 API header files anymore
362 - only the API relevant header (and source) files will be exported to
363 the Doxygen API documentation (explicitly listed in Doxyfile.in)
364 - added completely new XCode project files for Mac OSX which is now
365 capable to execute our autoconf environment, thus no need anymore
366 to maintain the compile time configuration file (osx/version.h) for
367 OSX manually (patch by Toshi Nagata)
368 - fixed buggy boolean --enable-foo / --disable-foo configure script
369 parameters
370 - global.h now only covers global definitions that are needed for the
371 C++ API header files, all implementation internal global definitions
372 are now in global_private.h
373 - atomic.h is not exposed to the C++ API anymore
374 - no need to include config.h anymore for using LS's API header files
375 - fixed warnings in API doc generation
376
377 * general changes:
378 - replaced the old, confusing MIDI program change mechanism by a
379 flexible MIDI instrument mapper which allows to map arbitrary
380 (MIDI bank, MIDI program) pairs with arbitrary
381 (engine type, instrument file, file index) triplets which will be
382 loaded on the respective channel when such MIDI program change
383 messages arrive, beside that, each entry allows to define a life-time
384 strategy for the instrument, so the user can define whether the
385 instrument should i.e. be permanently loaded (to be able to switch
386 quickly among sounds) or i.e. loaded just on demand when the
387 respective program change arrives (to safe RAM space), as well as a
388 global volume factor for each entry, so the user can adjust the volume
389 dynamic of his mapped instrument collection without having to modify
390 the instrument files, also one can manage arbitrary amount of such
391 MIDI instrument maps and assign each sampler channel individually
392 a certain map, so that i.e. separation of normal instruments and
393 drumkits is possible
394 - new notification events for tracking changes to audio/MIDI devices,
395 MIDI instrument maps, MIDI instruments, FX sends, global volume.
396 - sampler was limited to load max. 200 instruments in the background
397 due to a constant size RingBuffer FIFO which is now replaced by a
398 dynamic (unlimited) size std::list FIFO
399 - added FX sends, these allow to route audio signals to arbitrary audio
400 output channels for being processed by external effect processors
401 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
402 controllers
403 - global (sampler wide) volume can now be controlled at runtime
404 - Implemented new, improved notification system
405 - fixed compilation errors regarding OSX
406 (patch by Toshi Nagata)
407 - implemented instruments database
408 - added support for escape sequences to the instruments database
409 - added highly experimental support for on-the-fly instrument editing
410 within the sampler's process (by using instrument editor plugins),
411 you'll notice the new "Registered instrument editors:" message on
412 startup, added a new LSCP command:
413 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
414 to spawn a matching instrument editor for the instrument on the
415 given sampler channel, the plugin path can be overridden at compile
416 time with ./configure --enable-plugin-dir=/some/dir
417 - added experimental code for synchronizing instrument editors hosted
418 in the sampler's process to safely edit instruments while playing
419 without a crash (hopefully) by either suspending single regions
420 wherever possible or if unavoidable whole engine(s)
421 - fixed several issues in fundamental "Thread" class: set scheduling
422 policy and priority on thread level, set a minimum stack size for
423 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
424 threads simply inherited properties of starting thread instead of
425 setting their own policy and priority
426 - minor fix in our automatic stack trace mechanism on crashes, the
427 main process did not wait for the stack trace process to finish
428 its output
429 - fixed some minor memory leaks
430 - reenabled assembly features support, at the moment only for
431 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
432 - minor assembly fix in x86 features detection (don't use the PIC
433 register, to avoid relocations in the text segment at runtime)
434 - POSIX callback functions of Thread.h are hidden
435
436 * MIDI driver:
437 - dispatch bank select (MSB and LSB) messages
438
439 * audio driver:
440 - the ALSA audio output driver parameters now reflect the correct
441 parameter value ranges for the respective selected sound card
442 (patch by Till Wimmer, a bit fixed and extended)
443
444 * Gigasampler format engine:
445 - if a filter is used and EG2 finishes before EG1, let the voice
446 die when EG2 has finished (this fixes a problem with clicks and
447 voice starvation for some gigs)
448 - playback is no longer disabled during instrument loading
449 - all notes playing on a channel that changes its instrument keep
450 playing with the old instrument until they get a note off
451 command
452 - EG fix: a release value of zero could cause noises or crash
453 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
454 - EG fine tuning: when attack is zero the EG starts at a level
455 above max sustain level, which means that there is a decay phase
456 even if sustain is 100%
457 - more EG fixes: the level could sometimes go below zero and cause
458 noises or crashes
459 - minor fix of EGDecay (patch by Toshi Nagata)
460 - fixed compiler error when --enable-override-filter-type was
461 supplied to the configure script (fixes #46)
462 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
463 instead of a fix value
464 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
465 127 (solo mode) only kill voices if the respective mode really
466 changed
467
468 * LSCP server:
469 - fixed compile time error for old Bison versions
470 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
471 - parser now supports extended ASCII character set
472 (up to ASCII code 255, i.e. includes now umlauts and accents)
473 - filename arguments in LSCP commands now allow to use escape
474 sequences, that is directly literal as one of: \', \", \\, \n, \r,
475 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
476 code value like \xf2) (fixes bug #24)
477 - the following LSCP commands now also support escape sequences for at
478 least one of their text-based parameters (i.e. name, description):
479 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
480 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
481 "SET DB_INSTRUMENT_DIRECTORY NAME",
482 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
483 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
484 "FIND DB_INSTRUMENT_DIRECTORIES"
485 - returns verbose syntax errors (line and column where syntax error
486 occured, the unexpected character and the actually expected, possible
487 character(s), the latter only if less than 5 possibilities)
488 - made sure that LSCP syntax is not affected by gigedit locale
489 settings
490 - bugfix regarding strings parameter lists: all comma separated lists
491 of strings were treated as being one string containing commas
492 (fixes #57)
493
494 * Bug fixes:
495 - fixed crash occurring on certain LSCP scripts (Bug 39)
496 - another thread safety fix for lscp "load engine" and "set
497 channel audio output device"
498 - fixed a crash which occurs when reassigning the same engine
499 on a sampler channel with connected MIDI device
500 - fixed a crash which occurs when changing the number of ports of a MIDI
501 device connected to a sampler channel to number less then or equal
502 to the index of the port to which the sampler channel is connected.
503 - The previous bindings were not been disconnected when altering
504 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
505 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
506 - The active stream/voice count statistic was incorrect.
507 - notification events were not been sent for some sampler
508 channel changes
509 - added default min and max values to restrict the number of allowed
510 audio output channels and MIDI input ports
511 - the connection to the PCM interface is now closed when destroying
512 an audio output device
513 - files with slash in their path or filename could not be loaded
514
515 * test cases:
516 - updated and fixed (haven't been touched in a while)
517
518 Version 0.4.0 (24 November 2006)
519
520 * packaging changes:
521 - changed deprecated copyright attribute to license; added ldconfig
522 to post-(un)install steps; added devel package for liblinuxsampler;
523 to linuxsampler.spec (RPM)
524 - install necessary development header files for allowing 3rd party
525 applications to link against liblinuxsampler
526 - liblinuxsampler's API documentation can be generated with 'make docs'
527 (Doxygen required)
528 - added benchmark to automatically detect the best triangle LFO
529 implementation (currently either an integer math solution or a
530 di-harmonic approximation), automatic detection can be overriden
531 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
532 configure script argument though (mandatory for cross-compilation)
533 - do not automatically pick optimized gcc flags if the user already
534 provided some on his own (as CXXFLAGS)
535 - added compile time option to disable processing of All-Notes-Off MIDI
536 messages
537 - added compile time options to allow disabling the various audio and
538 MIDI drivers
539 - fixed automatic GCC CPU switch detection on PPC
540 (patch by Ebrahim Mayat)
541
542 * Gigasampler format engine:
543 - extensive synthesis optimization
544 (reimplementation of EGs and LFO(s), removed synthesis parameter
545 prerendering and the synthesis parameter matrix in general, splitting
546 each audio fragment into subfragments now where each subfragment uses
547 constant pitch and filter coefficients. The volume coefficient is
548 linearly interpolated inside a subfragment, unless
549 --disable-interpolate-volume is set.)
550 - fine tuning of the EG modulation parameters
551 - improved filter cutoff calculation by adding support for the
552 following gig parameters: Cutoff freq (used when no cutoff
553 controller is defined), Control invert, Minimum cutoff, Velocity
554 curve and Velocity range. The keyboard tracking now scales
555 cutoff frequency instead of resonance.
556 - added support for gig parameter Resonance.
557 - fixed bug in sysex handling (patch by Juan Linietsky)
558 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
559 which can be overridden with --enable-global-attenuation
560 - EG fixes: made the length of "attack hold" stage more
561 accurate. Release stage can now start before attack stage
562 ends. Cancel release didn't work when sustain was zero. Attack
563 time now has a minimal value to prevent clicks.
564 - fixed pitch changes larger than one octave
565 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
566 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
567 all modes can be altered via standard GM messages, that is CC5 for
568 altering portamento time, CC65 for enabling / disabling portamento
569 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
570 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
571 parameter) and crossfade
572 - added support for the "attenuation controller threshold" gig
573 parameter
574 - added smoothing of volume changes caused by control change
575 messages
576 - sample loop parameters are now taken from the DimensionRegion
577 instead of the wave chunk
578 - fixed keyswitching for v3 gigs with a number of keyswitch splits
579 not equal to a power of two
580 - reimplementation of the filter algorithm. The new filter is more
581 accurate and supports all gig filter types, including bandreject
582 and lowpass turbo.
583 - real support for 24 bit samples - samples are not truncated to
584 16 bits anymore
585 - support for aftertouch (channel pressure, not polyphonic
586 aftertouch)
587 - LFO1 behaviour fixed (dampening from max volume instead of
588 amplifying from 0)
589
590 * LSCP server:
591 - fixed application exit on broken pipe error (fixes bug #20)
592 - fixed the notification messages delay due to lack of
593 network activity (fixes bug #26)
594 - fixed parser bug which occured on space(s) within device parameters
595 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
596
597 * audio driver:
598 - added aRts audio output driver (by no means RT safe)
599
600 * MIDI driver:
601 - fixed legacy sysex code which caused dispatching of MIDI SysEx
602 messages several times instead of once
603 - API extension for MIDI drivers which already supply exact time stamps
604 for events (i.e. for offline rendering based MIDI drivers)
605 - added checks for bad MIDI data
606
607 * linuxsampler application:
608 - show available sampler engine types on startup
609
610 * general changes:
611 - support for muting sampler channels and solo mode of the same, two new
612 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
613 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
614 introduced for this, the behavior is the same like on a mixer console
615 (patch by Grigor Iliev, a bit adjusted). Also added configure option
616 --enable-process-muted-channels which can be used to enable the
617 processing of muted channels.
618 - support for sostenuto pedal
619 - support for monitoring the total number of active voices
620 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
621 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
622 - fixed some memory management errors
623 - fixed some concurrency problems that could lead to crashes when
624 LSCP commands were executed
625 - fixed crash when instrument loading failed previously on the same
626 sampler channel (fixes bug #36)
627
628 Version 0.3.3 (15 July 2005)
629
630 * packaging changes:
631 - fixed compilation with gcc 4.0
632
633 * Gigasampler format engine:
634 - LFO preprocessing was performed even though the respective LFO was
635 disabled by the instrument patch (minor efficiency fix)
636 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
637 for volume ramp downs in the same fragment (needed for current voice
638 stealing implementation) then simply inform the user with a warning
639 about possible click sounds and reduce the volume ramp down
640 appropriately instead of cancelling the audio device connection
641
642 Version 0.3.2 (24 June 2005)
643
644 * packaging changes:
645 - updated autotools build files to compile on OS X
646 (conditional compilation of CoreMIDI and MidiShare drivers)
647 - hand-crafted assembly optimization code can be disabled with
648 './configure --disable-asm' (definitely not recommended)
649 - fixed 'make dist' rule to include all necessary files
650 - require automake (>= 1.5) for 'make -f Makefile.cvs'
651 (due to 'dist-bzip2' automake option)
652
653 * Gigasampler format engine:
654 - support for the gig parameters for "release velocity response" curves
655 - fine tuning of the EGADSR envelope
656 - volume of release triggered samples now depends on note-on velocity,
657 note length and gig parameter "release trigger decay" instead of
658 note-off velocity.
659 - revised voice stealing
660 (fixes crash and endless loop caused by voice stealing)
661 - don't reset scale tuning on instrument or audio output device change
662 - handle key group conflicts right at the beginning of each fragment
663 instead of when the respective voice is actually launched
664 (fixes undefined behavior if stolen voices belonged to a key group -
665 this case was followed by a "killed voice survived" error message)
666 - fixed minor issue with null/silence samples
667 (those stole voices even though they don't need a voice at all which
668 resulted in "voice stealing didn't work out" messages)
669 - don't reset volume, pan, pitch and MIDI controller values on
670 instrument or audio output device change
671
672 * LSCP server:
673 - fixed some crashes (patch by Grigor Iliev, fixes #19)
674 - fixed LSCP event "CHANNEL_INFO" notification
675 (e.g. did not notify on volume changes or MIDI program change events)
676
677 * linuxsampler application:
678 - added command line parameters --lscp-addr and --lscp-port to override
679 default IP address and port of LSCP server
680
681 Version 0.3.1 (24 May 2005)
682
683 * initial release
