82 schoenebeck 1599
83 schoenebeck 1639 * packaging changes:
84     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

111     unnecessarily long after an update
112 schoenebeck 1653 - 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)

116 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
117 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation

129 schoenebeck 1830 - 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 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
133     a pointer to the launched InstrumentEditor object
134 schoenebeck 1876 - added optional 3rd party user data parameter for following
135     liblinuxsampler C++ API methods: InstrumentEditor::Main(),

146     - removed the nonsense audio channel constraint (which was hard coded to
147     max. 100 audio channels) for most audio drivers
148 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
149     opposed to the LSCP specs

155 persson 1748 jack_client_new
156 iliev 1829 - added (experimental) CoreAudio driver
157 persson 1888 - 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 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
161     win64)
162 persson 1895 - VST: added support for sample rate and buffer size changes
163     - VST: close editor (Fantasia) when the VST is removed

172     AudioChannel::CopyTo() methods using GCC vector exensions
173     (if available)
174 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
175     exception when getting parameters from a disconnected device
176 schoenebeck 1599
177 persson 1651 * MIDI driver:
178     - added JACK MIDI driver
179 schoenebeck 1715 - 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 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
183 persson 1887 CoreMidi or AU
184 persson 1889 - fixed mingw-w64 compilation error in MME driver
185 persson 1924 - made program change handling in MIDI thread real-time safe by
186     moving the logic to a non-RT thread

197     instrument database compilable
198 schoenebeck 1930 - 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 persson 1943 - fixed recursive import, which was broken on Windows
206 iliev 1603
207 persson 1644 * Gigasampler format engine:
208     - fixed a memory leak that could happen when a channel was deleted
209     while notes were playing
210 persson 1646 - made it possible to load an instrument even if the audio thread
211     isn't running
212 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
213     enough for piano gigs with pedal noise samples
214 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
215     respective FX send MIDI controller was used
216 schoenebeck 1724 - added support for GM global device volume SysEx message
217 schoenebeck 1762 (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 persson 1748 - 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 schoenebeck 1750 - 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 persson 1764 - made it possible to create multiple sample channels even if the
231     audio thread isn't running
232 persson 1844 - fixed crash when removing channel with active voices (#116)
233 schoenebeck 1852 - 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 schoenebeck 1857 - 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 persson 1858 - added support for the "fine tune" and "pitch bend range"
242     instrument-level gig parameters
243     - fixed minor artifacts in pitch bend handling
244 schoenebeck 1860 - added support for GS Reset SysEx message
245 persson 1862 - allow gig files to use unlimited downward pitch shifting
246     - added a limit check for upward pitch shifting
247 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
248     note was silent
249 persson 1923 - fixed crash happening when a pitch bend event arrived at the
250     same time a new instrument was loading
251 persson 1644
252 schoenebeck 1687 * 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 schoenebeck 1695 - 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 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
260     SET DB_INSTRUMENT FILE_PATH
261 iliev 1771 - 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 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
266     was incorrect
267 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
268 schoenebeck 1800 - 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 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
275     a gigedit file dialog is opened)
276 iliev 1848 - close all connections when LSCPServer is deleted
277 iliev 1882 - hard close of all sockets on exit
278 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
279     driver
280 schoenebeck 1687
281 iliev 1761 * Bug fixes:
282     - fixed a crash which occurs when removing a sampler channel waiting
283     to start instrument loading after another channel
284 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
285     instrument loading in progress (bug #113)
286 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
287     instrument with PERSISTENT load mode
288 iliev 1835 - 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 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
296 iliev 1847 - fixed crash when changing the audio output device of a sampler
297     channel with loaded instrument and start playing notes
298 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
299 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
300     PowerPC, which probably could cause crashes on that platform
301 persson 1889 - fixed a memory management error which could cause a crash when a
302     plugin was unloaded
303 persson 1896 - bugfix: two private structs had the same name, which could cause
304     problems if the linker chose the wrong constructor
305 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
306     Windows
307 iliev 1761
308    
309 schoenebeck 1560 Version 0.5.1 (6 December 2007)
310 schoenebeck 1454
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 senoner 1502 - added autoconf checks for MS Windows
316 schoenebeck 1454
317 persson 1455 * general changes:
318     - bugfix: the thread used by an editor plugin didn't die when the
319     editor closed
320 persson 1534 - 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 iliev 1541 - 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 persson 1455
339 senoner 1500 * AUDIO driver:
340 persson 1534 - added Windows ASIO low latency audio driver
341 senoner 1500
342 senoner 1485 * MIDI driver:
343 schoenebeck 1495 - added MME Windows MIDI driver
344 senoner 1485
345 schoenebeck 1471 * 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 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
350     apostrophes as well
351 schoenebeck 1525 - 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 schoenebeck 1471
357 schoenebeck 1424 Version 0.5.0 (15 October 2007)
358 schoenebeck 947
359 schoenebeck 1065 * packaging changes:
360 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
361     API header files anymore
362 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
363     the Doxygen API documentation (explicitly listed in Doxyfile.in)
364 schoenebeck 1175 - 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 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
369     parameters
370 schoenebeck 1424 - 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 schoenebeck 1065
377 schoenebeck 947 * general changes:
378     - replaced the old, confusing MIDI program change mechanism by a
379     flexible MIDI instrument mapper which allows to map arbitrary
380 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
381 schoenebeck 947 (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 schoenebeck 973 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 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
395     MIDI instrument maps, MIDI instruments, FX sends, global volume.
396 schoenebeck 990 - 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 schoenebeck 1001 - 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 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
404 iliev 1130 - Implemented new, improved notification system
405 schoenebeck 1149 - fixed compilation errors regarding OSX
406     (patch by Toshi Nagata)
407 iliev 1161 - implemented instruments database
408 iliev 1345 - added support for escape sequences to the instruments database
409 schoenebeck 1212 - 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 schoenebeck 1407 startup, added a new LSCP command:
413     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
414 schoenebeck 1212 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 schoenebeck 1321 - 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 schoenebeck 1221 - 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 schoenebeck 1233 - 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 persson 1248 - fixed some minor memory leaks
430 schoenebeck 1259 - reenabled assembly features support, at the moment only for
431     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
432 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
433     register, to avoid relocations in the text segment at runtime)
434 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
435 schoenebeck 947
436     * MIDI driver:
437     - dispatch bank select (MSB and LSB) messages
438    
439 schoenebeck 1049 * 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 persson 951 * 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 persson 1038 - 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 persson 1039 - EG fix: a release value of zero could cause noises or crash
453 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
454 persson 1046 - 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 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
458     noises or crashes
459 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
460 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
461     supplied to the configure script (fixes #46)
462 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
463     instead of a fix value
464 schoenebeck 1348 - 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 persson 951
468 schoenebeck 1244 * 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 schoenebeck 1245 - 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 schoenebeck 1389 - 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 schoenebeck 1252 - 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 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
489     settings
490 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
491     of strings were treated as being one string containing commas
492     (fixes #57)
493 schoenebeck 1244
494 iliev 959 * Bug fixes:
495     - fixed crash occurring on certain LSCP scripts (Bug 39)
496 persson 1038 - another thread safety fix for lscp "load engine" and "set
497     channel audio output device"
498 iliev 1283 - fixed a crash which occurs when reassigning the same engine
499     on a sampler channel with connected MIDI device
500 iliev 1295 - 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 iliev 1296 - 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 iliev 1297 - The active stream/voice count statistic was incorrect.
507 iliev 1298 - notification events were not been sent for some sampler
508     channel changes
509 iliev 1305 - added default min and max values to restrict the number of allowed
510     audio output channels and MIDI input ports
511 iliev 1306 - the connection to the PCM interface is now closed when destroying
512     an audio output device
513 schoenebeck 1332 - files with slash in their path or filename could not be loaded
514 iliev 959
515 schoenebeck 1221 * test cases:
516     - updated and fixed (haven't been touched in a while)
517    
518 schoenebeck 937 Version 0.4.0 (24 November 2006)
519 persson 696
520 schoenebeck 697 * packaging changes:
521 capela 868 - 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 schoenebeck 697 - 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 schoenebeck 715 - 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 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
534     provided some on his own (as CXXFLAGS)
535 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
536     messages
537 schoenebeck 852 - added compile time options to allow disabling the various audio and
538     MIDI drivers
539 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
540     (patch by Ebrahim Mayat)
541 schoenebeck 697
542 persson 696 * Gigasampler format engine:
543 schoenebeck 738 - 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 persson 830 constant pitch and filter coefficients. The volume coefficient is
548     linearly interpolated inside a subfragment, unless
549     --disable-interpolate-volume is set.)
550 persson 696 - fine tuning of the EG modulation parameters
551 persson 729 - 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 persson 791 curve and Velocity range. The keyboard tracking now scales
555     cutoff frequency instead of resonance.
556 persson 877 - added support for gig parameter Resonance.
557 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
558 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
559     which can be overridden with --enable-global-attenuation
560 persson 783 - EG fixes: made the length of "attack hold" stage more
561     accurate. Release stage can now start before attack stage
562 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
563     time now has a minimal value to prevent clicks.
564 persson 799 - fixed pitch changes larger than one octave
565 schoenebeck 829 - 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 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
571     parameter) and crossfade
572 persson 831 - added support for the "attenuation controller threshold" gig
573     parameter
574 persson 832 - added smoothing of volume changes caused by control change
575     messages
576 persson 865 - 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 persson 877 - 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 persson 903 - 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 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
588     amplifying from 0)
589 persson 696
590 schoenebeck 711 * LSCP server:
591     - fixed application exit on broken pipe error (fixes bug #20)
592 iliev 793 - fixed the notification messages delay due to lack of
593     network activity (fixes bug #26)
594 schoenebeck 826 - 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 schoenebeck 711
597 schoenebeck 838 * audio driver:
598     - added aRts audio output driver (by no means RT safe)
599    
600 schoenebeck 775 * MIDI driver:
601     - fixed legacy sysex code which caused dispatching of MIDI SysEx
602     messages several times instead of once
603 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
604     for events (i.e. for offline rendering based MIDI drivers)
605 persson 922 - added checks for bad MIDI data
606 schoenebeck 775
607 schoenebeck 900 * linuxsampler application:
608     - show available sampler engine types on startup
609    
610 schoenebeck 705 * 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 iliev 716 (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 iliev 777 - support for sostenuto pedal
619 iliev 779 - support for monitoring the total number of active voices
620 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
621     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
622 persson 835 - fixed some memory management errors
623 persson 841 - fixed some concurrency problems that could lead to crashes when
624     LSCP commands were executed
625 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
626     sampler channel (fixes bug #36)
627 schoenebeck 705
628 schoenebeck 692 Version 0.3.3 (15 July 2005)
629 schoenebeck 686
630     * packaging changes:
631     - fixed compilation with gcc 4.0
632    
633 schoenebeck 687 * Gigasampler format engine:
634     - LFO preprocessing was performed even though the respective LFO was
635     disabled by the instrument patch (minor efficiency fix)
636 schoenebeck 688 - 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 schoenebeck 687
642 schoenebeck 677 Version 0.3.2 (24 June 2005)
643 schoenebeck 609
644     * packaging changes:
645     - updated autotools build files to compile on OS X
646     (conditional compilation of CoreMIDI and MidiShare drivers)
647 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
648     './configure --disable-asm' (definitely not recommended)
649 schoenebeck 654 - 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 schoenebeck 649
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 schoenebeck 663 - revised voice stealing
660     (fixes crash and endless loop caused by voice stealing)
661 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
662 schoenebeck 668 - 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 schoenebeck 669 - 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 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
670     instrument or audio output device change
671 schoenebeck 654
672 schoenebeck 620 * LSCP server:
673 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
674 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
675 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
676 schoenebeck 609
677 schoenebeck 668 * 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 schoenebeck 579 Version 0.3.1 (24 May 2005)
682    
683     * initial release
