File size: 32467 byte(s)
* VST bugfix: If the host called resume() before and after changing
  sample rate or block size, the number of channels was incorrectly
  set to two. This caused silence in Cubase 5.
* removed compiler warnings

1 Version CVS HEAD (?)
2
3 * General changes:
4 - Refactoring: moved the independent code from
5 the Gigasampler format engine to base classes
6
7 * Gigasampler format engine:
8 - implemented the "round robin keyboard" dimension
9 - fixed round robin and random dimensions for cases when number of
10 dimension zones is not a power of two
11 - made round robin use a counter for each region instead of each
12 key
13
14 * SFZ format engine
15 - Initial implementation (not usable yet)
16
17 * SoundFont format engine
18 - Initial implementation (not usable yet)
19
20 * Host plugins:
21 - AU bugfix: failed to destroy its audio/MIDI devices
22 - Listen to all interfaces on Mac OS X (INADDR_ANY)
23 - VST bugfix: If the host called resume() before and after
24 changing sample rate or block size, the number of channels was
25 incorrectly set to two. This caused silence in Cubase 5.
26
27 * MIDI driver:
28 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
29 the ALSA sequencer client name
30
31 * LSCP server:
32 - added support for sending MIDI CC messages via LSCP command
33 "SEND CHANNEL MIDI_DATA CC <sampler-chan> <ctrl> <val>"
34
35 * Bug fixes:
36 - Fixed crash which may occur when MIDI key + transpose is out of range
37
38 Version 1.0.0 (31 July 2009)
39
40 * packaging changes:
41 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
42 causing e.g. the libgig test to fail when
43 "./configure --disable-jack-driver" was used
44 (patch by Alexis Ballier)
45 - fixed compilation with gcc 4.3
46 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
47 - fixed configure so it detects x86_64 (#107)
48 - fixes for building with newer MinGW versions
49 - fix for building with bison 2.4 (#111)
50 - fixed building with libgig installed in a non-standard directory
51 - minor fix in configure for mmsystem.h detection on MinGW
52 - Windows: look for editor plugins and Fantasia using base
53 directory of liblinuxsampler dll (look in the same directory and one
54 directory above)
55 - configure script fix: removed unconditional use of SSE
56 - fixed building with sqlite installed in a non-standard directory
57 - when cross-compiling, don't try to create instruments.db
58 - fix for new mingw-w64 version, which has usleep
59
60 * general changes:
61 - bugfix: on some POSIX systems instrument editor plugins refused to
62 load as we used a non-portable Linux specific struct field
63 (fixes bug #70, patch by Ronald Baljeu)
64 - fixed endless loop which occured when loading an instrument editor
65 plugin DLL on Windows systems failed
66 - fixed memory leaks that occurred when liblinuxsampler was unloaded
67 - optimized the SynchronizedConfig class so it doesn't wait
68 unnecessarily long after an update
69 - added support for notifying instrument editors on note-on / note-off
70 events (e.g. to highlight the pressed keys on the virtual keyboard
71 of gigedit)
72 - added support for triggering notes by instrument editors (see above)
73 - be verbose on DLL load errors (on Linux)
74 - fixed di-harmonic triangle LFO implementation (this LFO implementation
75 is only used by very few systems, most pick the int math
76 implementation, which is usually faster)
77 - fixes for audio drivers with varying buffer sizes
78 - experimental support for running LinuxSampler as a DSSI, LV2 and
79 VST plugin
80 - notification events for stream/voice count statistics are now sent
81 only when there are actual changes
82 - added memory ordering constraints to improve stability on
83 multi-core and multi-cpu systems
84 - maximum voices and disk streams can now be altered at runtime
85 - fixed CPU feature detection on x86_64 (maybe fixes #108)
86 - automatic stacktrace mechanism is now turned off by default and can
87 be switched on by command line option "--stacktrace" (the automatic
88 stacktrace mechanism seems to be broken on most systems at the moment)
89 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
90 a pointer to the launched InstrumentEditor object
91 - added optional 3rd party user data parameter for following
92 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
93 InstrumentEditor::Launch(),
94 InstrumentManager::LaunchInstrumentEditor()
95 - theoretical fix: made SynchronizedConfig follow C++0x memory
96 model more strictly
97 - fixes for using large audio device buffers
98 - Windows: add the installation directory to the DLL search path
99 when loading an editor plugin (solves problems with VST and
100 gigedit on systems with other GTK versions installed)
101
102 * audio driver:
103 - removed the nonsense audio channel constraint (which was hard coded to
104 max. 100 audio channels) for most audio drivers
105 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
106 opposed to the LSCP specs
107 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
108 reflected the wrong value
109 - fixed a memory management bug in ASIO driver
110 - Makefile fix: JACK_CFLAGS wasn't used
111 - JACK: use jack_client_open instead of the deprecated
112 jack_client_new
113 - added (experimental) CoreAudio driver
114 - applied old fixes to the ASIO driver that were included in the
115 previous binary release but accidentally never committed to CVS
116 (fixes #117)
117 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
118 win64)
119 - VST: added support for sample rate and buffer size changes
120 - VST: close editor (Fantasia) when the VST is removed
121 - VST: avoid opening Fantasia more than once for each VST instance
122 - VST: export main function as "main" on Linux too (fix for
123 energyXT)
124 - VST: changed number of output channels from one stereo to 16
125 stereo
126 - added channel routing, fxsends and midi maps to the settings
127 stored in the plugin state
128 - performance optimization of AudioChannel::MixTo() and
129 AudioChannel::CopyTo() methods using GCC vector exensions
130 (if available)
131 - ASIO fixes: avoid initializing the device twice, avoid throwing
132 exception when getting parameters from a disconnected device
133
134 * MIDI driver:
135 - added JACK MIDI driver
136 - dispatch bank select as ordinary CC as well, the user might seriously
137 want to (mis)use it for some purpose ("fixed" in all current MIDI
138 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
139 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
140 CoreMidi or AU
141 - fixed mingw-w64 compilation error in MME driver
142 - made program change handling in MIDI thread real-time safe by
143 moving the logic to a non-RT thread
144 - fixed minor memory leak in ALSA driver
145
146 * instruments database:
147 - avoid time consuming samples scanning when adding instruments
148 to the instruments database
149 - added support for handling lost files in the instruments database
150 - Implemented option for adding instruments in separate directories
151 in the instruments database
152 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
153 - work-around for missing fnmatch function on Windows to make
154 instrument database compilable
155 - added instrument database support on Windows
156 works with both standalone mode and VST plugin.
157 the instruments DB file is located in
158 %USERPROFILE%\.linuxsampler\instruments.db which allows different
159 databases for each windows user
160 if no DB is present it automatically creates the .linuxsampler subdir
161 and then creates an empty DB
162 - fixed recursive import, which was broken on Windows
163
164 * Gigasampler format engine:
165 - fixed a memory leak that could happen when a channel was deleted
166 while notes were playing
167 - made it possible to load an instrument even if the audio thread
168 isn't running
169 - added partial support for the "Controller Triggered" MIDI rule,
170 enough for piano gigs with pedal noise samples
171 - minor fix: only mark FX sends as being modified if really the
172 respective FX send MIDI controller was used
173 - added support for GM global device volume SysEx message
174 (can be selected at compile time to either apply globally to the
175 whole sampler [default] or only to the sampler channels that are
176 connected to the respective MIDI input port the SysEx message arrived
177 on)
178 - bugfix: notes triggered at position 0 in the audio buffer were
179 sometimes wrongly killed in the same buffer, causing no sound to
180 be played
181 - added support for chromatic / drumkit mode Roland GS Sysex message
182 which is usally used to switch a part between chromatic sounds and
183 drumkit sounds (as opposed to their common default setting of MIDI
184 part 10 being a drumkit part and all other ones chromatic parts), in
185 LS however one can switch between the first 16 MIDI instrument maps
186 defined for the sampler
187 - made it possible to create multiple sample channels even if the
188 audio thread isn't running
189 - fixed crash when removing channel with active voices (#116)
190 - bugfix: on sample reference changes (instrument editor), only
191 un-cache the respective sample if it's really not used by any
192 sampler engine anymore
193 - re-cache samples in case they were changed by an instrument editor,
194 e.g. when a sample was added while playing (#82)
195 - fixed hanging notes which occured when note-off event had the exact
196 same time stamp as the voice's note-on event and occured both in the
197 same audio fragment cycle (fixes bug #112)
198 - added support for the "fine tune" and "pitch bend range"
199 instrument-level gig parameters
200 - fixed minor artifacts in pitch bend handling
201 - added support for GS Reset SysEx message
202 - allow gig files to use unlimited downward pitch shifting
203 - added a limit check for upward pitch shifting
204 - bugfix: sometimes, when playing a note twice fast, the second
205 note was silent
206 - fixed crash happening when a pitch bend event arrived at the
207 same time a new instrument was loading
208
209 * LSCP server:
210 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
211 react on MIDI data arriving on certain sampler channels (so far only
212 Note-On and Note-Off events are sent via this LSCP event)
213 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
214 react on MIDI data arriving on certain MIDI input devices (so far only
215 Note-On and Note-Off events are sent via this LSCP event)
216 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
217 SET DB_INSTRUMENT FILE_PATH
218 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
219 frontends to send MIDI messages to specific sampler channel
220 - added two additional fields to GET FILE INSTRUMENT INFO command -
221 KEY_BINDINGS and KEYSWITCH_BINDINGS
222 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
223 was incorrect
224 - Optimized the retrieval of the MIDI instrument mappings
225 - added new LSCP command "SET VOICES" to globally alter the maximum
226 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
227 be triggered respectively
228 - added new LSCP command "SET STREAMS" to globally alter the maximum
229 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
230 which will be triggered respectively
231 - bugfix: retry if "select" returns EINTR (this fixes a crash when
232 a gigedit file dialog is opened)
233 - close all connections when LSCPServer is deleted
234 - hard close of all sockets on exit
235 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
236 driver
237
238 * Bug fixes:
239 - fixed a crash which occurs when removing a sampler channel waiting
240 to start instrument loading after another channel
241 - fixed a crash which occurs when removing a sampler channel with
242 instrument loading in progress (bug #113)
243 - fixed termination caused by uncaught exception when adding MIDI
244 instrument with PERSISTENT load mode
245 - fixed possible iterator invalidations when resetting the sampler
246 - fixed memory leaks when issuing the following LSCP commands:
247 GET AUDIO_OUTPUT_DRIVER INFO
248 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
249 GET MIDI_INPUT_DRIVER INFO
250 GET MIDI_INPUT_DRIVER_PARAMETER INFO
251 - fixed possible compilation error when sqlite is not present
252 - fixed orphaned pointers when setting maximum voices limit (bug #118)
253 - fixed crash when changing the audio output device of a sampler
254 channel with loaded instrument and start playing notes
255 - fixed endless loop in Engine::SuspendAll() (bug #120)
256 - fixed a low-level atomic load function that was broken on 64-bit
257 PowerPC, which probably could cause crashes on that platform
258 - fixed a memory management error which could cause a crash when a
259 plugin was unloaded
260 - bugfix: two private structs had the same name, which could cause
261 problems if the linker chose the wrong constructor
262 - fixed low-level ConditionServer usage bug that caused lockups on
263 Windows
264
265
266 Version 0.5.1 (6 December 2007)
267
268 * packaging changes:
269 - added autoconf checks for pthread library
270 - added autoconf check for pthread bug found on certain NPTL-enabled
271 glibc versions (see Gentoo bug report #194076)
272 - added autoconf checks for MS Windows
273
274 * general changes:
275 - bugfix: the thread used by an editor plugin didn't die when the
276 editor closed
277 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
278 out all the space. operator--() did not apply size_mask after
279 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
280 order to avoid problems with the _NonVolatileReader functions.
281 - bugfix: Stream.h: added a missing divide by BytesPerSample in
282 GetWriteSpace(). Since this function is currently only used in
283 the stream's qsort() compare function, it didn't trigger any
284 bugs.
285 - Resampler.h, Synthesizer.h: cubic interpolation now works in
286 24bit mode too. Faster method to read 24bit words on little
287 endian machines (x86): replaced 3 byte reads + shifts with a 1
288 unaligned 32bit read and shift
289 - experimental support for MS Windows (MIDI input via MME, AUDIO
290 output via ASIO)
291 - made handling of SIGINT signal (Ctrl-C) a bit more robust
292 - support for monitoring the total number of active disk streams
293 (new LSCP commands: GET TOTAL_STREAM_COUNT,
294 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
295
296 * AUDIO driver:
297 - added Windows ASIO low latency audio driver
298
299 * MIDI driver:
300 - added MME Windows MIDI driver
301
302 * LSCP server:
303 - added support for Windows style path / filenames, however with
304 forward slash path separators instead of backslash
305 (i.e. "C:/foo/bar.gig")
306 - allow naughty liblscp to send non-string device parameters within
307 apostrophes as well
308 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
309 "LIST FILE INSTRUMENTS <file>" and
310 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
311 about an arbitrary instrument file on the system where the sampler is
312 running on
313
314 Version 0.5.0 (15 October 2007)
315
316 * packaging changes:
317 - config.h is not going to be installed along with liblinuxsampler's
318 API header files anymore
319 - only the API relevant header (and source) files will be exported to
320 the Doxygen API documentation (explicitly listed in Doxyfile.in)
321 - added completely new XCode project files for Mac OSX which is now
322 capable to execute our autoconf environment, thus no need anymore
323 to maintain the compile time configuration file (osx/version.h) for
324 OSX manually (patch by Toshi Nagata)
325 - fixed buggy boolean --enable-foo / --disable-foo configure script
326 parameters
327 - global.h now only covers global definitions that are needed for the
328 C++ API header files, all implementation internal global definitions
329 are now in global_private.h
330 - atomic.h is not exposed to the C++ API anymore
331 - no need to include config.h anymore for using LS's API header files
332 - fixed warnings in API doc generation
333
334 * general changes:
335 - replaced the old, confusing MIDI program change mechanism by a
336 flexible MIDI instrument mapper which allows to map arbitrary
337 (MIDI bank, MIDI program) pairs with arbitrary
338 (engine type, instrument file, file index) triplets which will be
339 loaded on the respective channel when such MIDI program change
340 messages arrive, beside that, each entry allows to define a life-time
341 strategy for the instrument, so the user can define whether the
342 instrument should i.e. be permanently loaded (to be able to switch
343 quickly among sounds) or i.e. loaded just on demand when the
344 respective program change arrives (to safe RAM space), as well as a
345 global volume factor for each entry, so the user can adjust the volume
346 dynamic of his mapped instrument collection without having to modify
347 the instrument files, also one can manage arbitrary amount of such
348 MIDI instrument maps and assign each sampler channel individually
349 a certain map, so that i.e. separation of normal instruments and
350 drumkits is possible
351 - new notification events for tracking changes to audio/MIDI devices,
352 MIDI instrument maps, MIDI instruments, FX sends, global volume.
353 - sampler was limited to load max. 200 instruments in the background
354 due to a constant size RingBuffer FIFO which is now replaced by a
355 dynamic (unlimited) size std::list FIFO
356 - added FX sends, these allow to route audio signals to arbitrary audio
357 output channels for being processed by external effect processors
358 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
359 controllers
360 - global (sampler wide) volume can now be controlled at runtime
361 - Implemented new, improved notification system
362 - fixed compilation errors regarding OSX
363 (patch by Toshi Nagata)
364 - implemented instruments database
365 - added support for escape sequences to the instruments database
366 - added highly experimental support for on-the-fly instrument editing
367 within the sampler's process (by using instrument editor plugins),
368 you'll notice the new "Registered instrument editors:" message on
369 startup, added a new LSCP command:
370 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
371 to spawn a matching instrument editor for the instrument on the
372 given sampler channel, the plugin path can be overridden at compile
373 time with ./configure --enable-plugin-dir=/some/dir
374 - added experimental code for synchronizing instrument editors hosted
375 in the sampler's process to safely edit instruments while playing
376 without a crash (hopefully) by either suspending single regions
377 wherever possible or if unavoidable whole engine(s)
378 - fixed several issues in fundamental "Thread" class: set scheduling
379 policy and priority on thread level, set a minimum stack size for
380 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
381 threads simply inherited properties of starting thread instead of
382 setting their own policy and priority
383 - minor fix in our automatic stack trace mechanism on crashes, the
384 main process did not wait for the stack trace process to finish
385 its output
386 - fixed some minor memory leaks
387 - reenabled assembly features support, at the moment only for
388 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
389 - minor assembly fix in x86 features detection (don't use the PIC
390 register, to avoid relocations in the text segment at runtime)
391 - POSIX callback functions of Thread.h are hidden
392
393 * MIDI driver:
394 - dispatch bank select (MSB and LSB) messages
395
396 * audio driver:
397 - the ALSA audio output driver parameters now reflect the correct
398 parameter value ranges for the respective selected sound card
399 (patch by Till Wimmer, a bit fixed and extended)
400
401 * Gigasampler format engine:
402 - if a filter is used and EG2 finishes before EG1, let the voice
403 die when EG2 has finished (this fixes a problem with clicks and
404 voice starvation for some gigs)
405 - playback is no longer disabled during instrument loading
406 - all notes playing on a channel that changes its instrument keep
407 playing with the old instrument until they get a note off
408 command
409 - EG fix: a release value of zero could cause noises or crash
410 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
411 - EG fine tuning: when attack is zero the EG starts at a level
412 above max sustain level, which means that there is a decay phase
413 even if sustain is 100%
414 - more EG fixes: the level could sometimes go below zero and cause
415 noises or crashes
416 - minor fix of EGDecay (patch by Toshi Nagata)
417 - fixed compiler error when --enable-override-filter-type was
418 supplied to the configure script (fixes #46)
419 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
420 instead of a fix value
421 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
422 127 (solo mode) only kill voices if the respective mode really
423 changed
424
425 * LSCP server:
426 - fixed compile time error for old Bison versions
427 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
428 - parser now supports extended ASCII character set
429 (up to ASCII code 255, i.e. includes now umlauts and accents)
430 - filename arguments in LSCP commands now allow to use escape
431 sequences, that is directly literal as one of: \', \", \\, \n, \r,
432 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
433 code value like \xf2) (fixes bug #24)
434 - the following LSCP commands now also support escape sequences for at
435 least one of their text-based parameters (i.e. name, description):
436 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
437 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
438 "SET DB_INSTRUMENT_DIRECTORY NAME",
439 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
440 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
441 "FIND DB_INSTRUMENT_DIRECTORIES"
442 - returns verbose syntax errors (line and column where syntax error
443 occured, the unexpected character and the actually expected, possible
444 character(s), the latter only if less than 5 possibilities)
445 - made sure that LSCP syntax is not affected by gigedit locale
446 settings
447 - bugfix regarding strings parameter lists: all comma separated lists
448 of strings were treated as being one string containing commas
449 (fixes #57)
450
451 * Bug fixes:
452 - fixed crash occurring on certain LSCP scripts (Bug 39)
453 - another thread safety fix for lscp "load engine" and "set
454 channel audio output device"
455 - fixed a crash which occurs when reassigning the same engine
456 on a sampler channel with connected MIDI device
457 - fixed a crash which occurs when changing the number of ports of a MIDI
458 device connected to a sampler channel to number less then or equal
459 to the index of the port to which the sampler channel is connected.
460 - The previous bindings were not been disconnected when altering
461 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
462 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
463 - The active stream/voice count statistic was incorrect.
464 - notification events were not been sent for some sampler
465 channel changes
466 - added default min and max values to restrict the number of allowed
467 audio output channels and MIDI input ports
468 - the connection to the PCM interface is now closed when destroying
469 an audio output device
470 - files with slash in their path or filename could not be loaded
471
472 * test cases:
473 - updated and fixed (haven't been touched in a while)
474
475 Version 0.4.0 (24 November 2006)
476
477 * packaging changes:
478 - changed deprecated copyright attribute to license; added ldconfig
479 to post-(un)install steps; added devel package for liblinuxsampler;
480 to linuxsampler.spec (RPM)
481 - install necessary development header files for allowing 3rd party
482 applications to link against liblinuxsampler
483 - liblinuxsampler's API documentation can be generated with 'make docs'
484 (Doxygen required)
485 - added benchmark to automatically detect the best triangle LFO
486 implementation (currently either an integer math solution or a
487 di-harmonic approximation), automatic detection can be overriden
488 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
489 configure script argument though (mandatory for cross-compilation)
490 - do not automatically pick optimized gcc flags if the user already
491 provided some on his own (as CXXFLAGS)
492 - added compile time option to disable processing of All-Notes-Off MIDI
493 messages
494 - added compile time options to allow disabling the various audio and
495 MIDI drivers
496 - fixed automatic GCC CPU switch detection on PPC
497 (patch by Ebrahim Mayat)
498
499 * Gigasampler format engine:
500 - extensive synthesis optimization
501 (reimplementation of EGs and LFO(s), removed synthesis parameter
502 prerendering and the synthesis parameter matrix in general, splitting
503 each audio fragment into subfragments now where each subfragment uses
504 constant pitch and filter coefficients. The volume coefficient is
505 linearly interpolated inside a subfragment, unless
506 --disable-interpolate-volume is set.)
507 - fine tuning of the EG modulation parameters
508 - improved filter cutoff calculation by adding support for the
509 following gig parameters: Cutoff freq (used when no cutoff
510 controller is defined), Control invert, Minimum cutoff, Velocity
511 curve and Velocity range. The keyboard tracking now scales
512 cutoff frequency instead of resonance.
513 - added support for gig parameter Resonance.
514 - fixed bug in sysex handling (patch by Juan Linietsky)
515 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
516 which can be overridden with --enable-global-attenuation
517 - EG fixes: made the length of "attack hold" stage more
518 accurate. Release stage can now start before attack stage
519 ends. Cancel release didn't work when sustain was zero. Attack
520 time now has a minimal value to prevent clicks.
521 - fixed pitch changes larger than one octave
522 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
523 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
524 all modes can be altered via standard GM messages, that is CC5 for
525 altering portamento time, CC65 for enabling / disabling portamento
526 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
527 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
528 parameter) and crossfade
529 - added support for the "attenuation controller threshold" gig
530 parameter
531 - added smoothing of volume changes caused by control change
532 messages
533 - sample loop parameters are now taken from the DimensionRegion
534 instead of the wave chunk
535 - fixed keyswitching for v3 gigs with a number of keyswitch splits
536 not equal to a power of two
537 - reimplementation of the filter algorithm. The new filter is more
538 accurate and supports all gig filter types, including bandreject
539 and lowpass turbo.
540 - real support for 24 bit samples - samples are not truncated to
541 16 bits anymore
542 - support for aftertouch (channel pressure, not polyphonic
543 aftertouch)
544 - LFO1 behaviour fixed (dampening from max volume instead of
545 amplifying from 0)
546
547 * LSCP server:
548 - fixed application exit on broken pipe error (fixes bug #20)
549 - fixed the notification messages delay due to lack of
550 network activity (fixes bug #26)
551 - fixed parser bug which occured on space(s) within device parameters
552 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
553
554 * audio driver:
555 - added aRts audio output driver (by no means RT safe)
556
557 * MIDI driver:
558 - fixed legacy sysex code which caused dispatching of MIDI SysEx
559 messages several times instead of once
560 - API extension for MIDI drivers which already supply exact time stamps
561 for events (i.e. for offline rendering based MIDI drivers)
562 - added checks for bad MIDI data
563
564 * linuxsampler application:
565 - show available sampler engine types on startup
566
567 * general changes:
568 - support for muting sampler channels and solo mode of the same, two new
569 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
570 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
571 introduced for this, the behavior is the same like on a mixer console
572 (patch by Grigor Iliev, a bit adjusted). Also added configure option
573 --enable-process-muted-channels which can be used to enable the
574 processing of muted channels.
575 - support for sostenuto pedal
576 - support for monitoring the total number of active voices
577 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
578 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
579 - fixed some memory management errors
580 - fixed some concurrency problems that could lead to crashes when
581 LSCP commands were executed
582 - fixed crash when instrument loading failed previously on the same
583 sampler channel (fixes bug #36)
584
585 Version 0.3.3 (15 July 2005)
586
587 * packaging changes:
588 - fixed compilation with gcc 4.0
589
590 * Gigasampler format engine:
591 - LFO preprocessing was performed even though the respective LFO was
592 disabled by the instrument patch (minor efficiency fix)
593 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
594 for volume ramp downs in the same fragment (needed for current voice
595 stealing implementation) then simply inform the user with a warning
596 about possible click sounds and reduce the volume ramp down
597 appropriately instead of cancelling the audio device connection
598
599 Version 0.3.2 (24 June 2005)
600
601 * packaging changes:
602 - updated autotools build files to compile on OS X
603 (conditional compilation of CoreMIDI and MidiShare drivers)
604 - hand-crafted assembly optimization code can be disabled with
605 './configure --disable-asm' (definitely not recommended)
606 - fixed 'make dist' rule to include all necessary files
607 - require automake (>= 1.5) for 'make -f Makefile.cvs'
608 (due to 'dist-bzip2' automake option)
609
610 * Gigasampler format engine:
611 - support for the gig parameters for "release velocity response" curves
612 - fine tuning of the EGADSR envelope
613 - volume of release triggered samples now depends on note-on velocity,
614 note length and gig parameter "release trigger decay" instead of
615 note-off velocity.
616 - revised voice stealing
617 (fixes crash and endless loop caused by voice stealing)
618 - don't reset scale tuning on instrument or audio output device change
619 - handle key group conflicts right at the beginning of each fragment
620 instead of when the respective voice is actually launched
621 (fixes undefined behavior if stolen voices belonged to a key group -
622 this case was followed by a "killed voice survived" error message)
623 - fixed minor issue with null/silence samples
624 (those stole voices even though they don't need a voice at all which
625 resulted in "voice stealing didn't work out" messages)
626 - don't reset volume, pan, pitch and MIDI controller values on
627 instrument or audio output device change
628
629 * LSCP server:
630 - fixed some crashes (patch by Grigor Iliev, fixes #19)
631 - fixed LSCP event "CHANNEL_INFO" notification
632 (e.g. did not notify on volume changes or MIDI program change events)
633
634 * linuxsampler application:
635 - added command line parameters --lscp-addr and --lscp-port to override
636 default IP address and port of LSCP server
637
638 Version 0.3.1 (24 May 2005)
639
640 * initial release
