File size: 31190 byte(s)
* ASIO fixes: avoid initializing the device twice, avoid throwing
  exception when getting parameters from a disconnected device
* Windows: add the installation directory to the DLL search path when
  loading an editor plugin (solves problems with VST and gigedit on
  systems with other GTK versions installed)
* fixed minor memory leak in ALSA MIDI driver

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