7 iliev 2012 - Refactoring: moved the independent code from
8     the Gigasampler format engine to base classes
9 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
10     respective profiling code is currently broken
11 schoenebeck 2053 - Introduced support for optional environment variable
12     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory

15 iliev 2012
16 persson 2043 * Gigasampler format engine:
17     - implemented the "round robin keyboard" dimension
18     - fixed round robin and random dimensions for cases when number of
19     dimension zones is not a power of two
20     - made round robin use a counter for each region instead of each
21     key
22    
23 schoenebeck 2047 * SFZ format engine:
24 iliev 2012 - Initial implementation (not usable yet)
25 persson 2055 - added support for v2 multiple stage envelope generators
26     - added a fine-tuned v1 envelope generator instead of using the
27     one from the gig engine

29 persson 2061 - added support for trigger=first, trigger=legato and sw_previous
30 persson 2058 - allow non-numerical key values ("C#4" for example)
31     - "key" opcode now sets pitch_keycenter too
32     - fixed error when unloading instrument with same sample used by

59 persson 2045 - VST bugfix: If the host called resume() before and after
60     changing sample rate or block size, the number of channels was
61     incorrectly set to two. This caused silence in Cubase 5.
62 schoenebeck 1993
63     * MIDI driver:

104     unnecessarily long after an update
105 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
106     events (e.g. to highlight the pressed keys on the virtual keyboard
107     of gigedit)
108 schoenebeck 1659 - added support for triggering notes by instrument editors (see above)
109 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
110 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation

121 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
122 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
123     be switched on by command line option "--stacktrace" (the automatic
124     stacktrace mechanism seems to be broken on most systems at the moment)
125 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
126     a pointer to the launched InstrumentEditor object
127 schoenebeck 1876 - added optional 3rd party user data parameter for following
128     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
129     InstrumentEditor::Launch(),

138 schoenebeck 1599 * audio driver:
139     - removed the nonsense audio channel constraint (which was hard coded to
140     max. 100 audio channels) for most audio drivers
141 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
142     opposed to the LSCP specs
143 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
144     reflected the wrong value

148 persson 1748 jack_client_new
149 iliev 1829 - added (experimental) CoreAudio driver
150 persson 1888 - applied old fixes to the ASIO driver that were included in the
151     previous binary release but accidentally never committed to CVS
152     (fixes #117)
153 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
154     win64)
155 persson 1895 - VST: added support for sample rate and buffer size changes
156     - VST: close editor (Fantasia) when the VST is removed

165     AudioChannel::CopyTo() methods using GCC vector exensions
166     (if available)
167 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
168     exception when getting parameters from a disconnected device
169 schoenebeck 1599
170 persson 1651 * MIDI driver:
171     - added JACK MIDI driver
172 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
173     want to (mis)use it for some purpose ("fixed" in all current MIDI
174     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
175 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
176 persson 1887 CoreMidi or AU
177 persson 1889 - fixed mingw-w64 compilation error in MME driver
178 persson 1924 - made program change handling in MIDI thread real-time safe by
179     moving the logic to a non-RT thread
180 persson 1951 - fixed minor memory leak in ALSA driver
181 persson 1651
182 schoenebeck 1604 * instruments database:
183 iliev 1603 - avoid time consuming samples scanning when adding instruments
184     to the instruments database

189 persson 1908 - work-around for missing fnmatch function on Windows to make
190     instrument database compilable
191 schoenebeck 1930 - added instrument database support on Windows
192     works with both standalone mode and VST plugin.
193     the instruments DB file is located in
194     %USERPROFILE%\.linuxsampler\instruments.db which allows different
195     databases for each windows user
196     if no DB is present it automatically creates the .linuxsampler subdir
197     and then creates an empty DB
198 persson 1943 - fixed recursive import, which was broken on Windows
199 iliev 1603
200 persson 1644 * Gigasampler format engine:
201     - fixed a memory leak that could happen when a channel was deleted
202     while notes were playing
203 persson 1646 - made it possible to load an instrument even if the audio thread
204     isn't running
205 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
206     enough for piano gigs with pedal noise samples
207 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
208     respective FX send MIDI controller was used
209 schoenebeck 1724 - added support for GM global device volume SysEx message
210 schoenebeck 1762 (can be selected at compile time to either apply globally to the
211     whole sampler [default] or only to the sampler channels that are
212     connected to the respective MIDI input port the SysEx message arrived
213     on)
214 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
215     sometimes wrongly killed in the same buffer, causing no sound to
216     be played
217 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
218     which is usally used to switch a part between chromatic sounds and
219     drumkit sounds (as opposed to their common default setting of MIDI
220     part 10 being a drumkit part and all other ones chromatic parts), in
221     LS however one can switch between the first 16 MIDI instrument maps
222     defined for the sampler
223 persson 1764 - made it possible to create multiple sample channels even if the
224     audio thread isn't running
225 persson 1844 - fixed crash when removing channel with active voices (#116)
226 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
227     un-cache the respective sample if it's really not used by any
228     sampler engine anymore
229     - re-cache samples in case they were changed by an instrument editor,
230     e.g. when a sample was added while playing (#82)
231 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
232     same time stamp as the voice's note-on event and occured both in the
233     same audio fragment cycle (fixes bug #112)
234 persson 1858 - added support for the "fine tune" and "pitch bend range"
235     instrument-level gig parameters
236     - fixed minor artifacts in pitch bend handling
237 schoenebeck 1860 - added support for GS Reset SysEx message
238 persson 1862 - allow gig files to use unlimited downward pitch shifting
239     - added a limit check for upward pitch shifting
240 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
241     note was silent
242 persson 1923 - fixed crash happening when a pitch bend event arrived at the
243     same time a new instrument was loading
244 persson 1644
245 schoenebeck 1687 * LSCP server:
246     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
247     react on MIDI data arriving on certain sampler channels (so far only
248     Note-On and Note-Off events are sent via this LSCP event)
249 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
250     react on MIDI data arriving on certain MIDI input devices (so far only
251     Note-On and Note-Off events are sent via this LSCP event)
252 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
253     SET DB_INSTRUMENT FILE_PATH
254 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
255     frontends to send MIDI messages to specific sampler channel
256     - added two additional fields to GET FILE INSTRUMENT INFO command -
257     KEY_BINDINGS and KEYSWITCH_BINDINGS
258 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
259     was incorrect
260 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
261 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
262     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
263     be triggered respectively
264     - added new LSCP command "SET STREAMS" to globally alter the maximum
265     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
266     which will be triggered respectively
267 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
268     a gigedit file dialog is opened)
269 iliev 1848 - close all connections when LSCPServer is deleted
270 iliev 1882 - hard close of all sockets on exit
271 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
272     driver
273 schoenebeck 1687
274 iliev 1761 * Bug fixes:
275     - fixed a crash which occurs when removing a sampler channel waiting
276     to start instrument loading after another channel
277 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
278     instrument loading in progress (bug #113)
279 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
280     instrument with PERSISTENT load mode
281 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
282     - fixed memory leaks when issuing the following LSCP commands:
283     GET AUDIO_OUTPUT_DRIVER INFO
284     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
285     GET MIDI_INPUT_DRIVER INFO
286     GET MIDI_INPUT_DRIVER_PARAMETER INFO
287     - fixed possible compilation error when sqlite is not present
288 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
289 iliev 1847 - fixed crash when changing the audio output device of a sampler
290     channel with loaded instrument and start playing notes
291 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
292 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
293     PowerPC, which probably could cause crashes on that platform
294 persson 1889 - fixed a memory management error which could cause a crash when a
295     plugin was unloaded
296 persson 1896 - bugfix: two private structs had the same name, which could cause
297     problems if the linker chose the wrong constructor
298 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
299     Windows
300 iliev 1761
301    
302 schoenebeck 1560 Version 0.5.1 (6 December 2007)
303 schoenebeck 1454
304     * packaging changes:
305     - added autoconf checks for pthread library
306     - added autoconf check for pthread bug found on certain NPTL-enabled
307     glibc versions (see Gentoo bug report #194076)
308 senoner 1502 - added autoconf checks for MS Windows
309 schoenebeck 1454
310 persson 1455 * general changes:
311     - bugfix: the thread used by an editor plugin didn't die when the
312     editor closed
313 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
314     out all the space. operator--() did not apply size_mask after
315     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
316     order to avoid problems with the _NonVolatileReader functions.
317     - bugfix: Stream.h: added a missing divide by BytesPerSample in
318     GetWriteSpace(). Since this function is currently only used in
319     the stream's qsort() compare function, it didn't trigger any
320     bugs.
321     - Resampler.h, Synthesizer.h: cubic interpolation now works in
322     24bit mode too. Faster method to read 24bit words on little
323     endian machines (x86): replaced 3 byte reads + shifts with a 1
324     unaligned 32bit read and shift
325     - experimental support for MS Windows (MIDI input via MME, AUDIO
326     output via ASIO)
327     - made handling of SIGINT signal (Ctrl-C) a bit more robust
328 iliev 1541 - support for monitoring the total number of active disk streams
329     (new LSCP commands: GET TOTAL_STREAM_COUNT,
330     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
331 persson 1455
332 senoner 1500 * AUDIO driver:
333 persson 1534 - added Windows ASIO low latency audio driver
334 senoner 1500
335 senoner 1485 * MIDI driver:
336 schoenebeck 1495 - added MME Windows MIDI driver
337 senoner 1485
338 schoenebeck 1471 * LSCP server:
339     - added support for Windows style path / filenames, however with
340     forward slash path separators instead of backslash
341     (i.e. "C:/foo/bar.gig")
342 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
343     apostrophes as well
344 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
345     "LIST FILE INSTRUMENTS <file>" and
346     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
347     about an arbitrary instrument file on the system where the sampler is
348     running on
349 schoenebeck 1471
350 schoenebeck 1424 Version 0.5.0 (15 October 2007)
351 schoenebeck 947
352 schoenebeck 1065 * packaging changes:
353 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
354     API header files anymore
355 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
356     the Doxygen API documentation (explicitly listed in Doxyfile.in)
357 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
358     capable to execute our autoconf environment, thus no need anymore
359     to maintain the compile time configuration file (osx/version.h) for
360     OSX manually (patch by Toshi Nagata)
361 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
362     parameters
363 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
364     C++ API header files, all implementation internal global definitions
365     are now in global_private.h
366     - atomic.h is not exposed to the C++ API anymore
367     - no need to include config.h anymore for using LS's API header files
368     - fixed warnings in API doc generation
369 schoenebeck 1065
370 schoenebeck 947 * general changes:
371     - replaced the old, confusing MIDI program change mechanism by a
372     flexible MIDI instrument mapper which allows to map arbitrary
373 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
374 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
375     loaded on the respective channel when such MIDI program change
376     messages arrive, beside that, each entry allows to define a life-time
377     strategy for the instrument, so the user can define whether the
378     instrument should i.e. be permanently loaded (to be able to switch
379     quickly among sounds) or i.e. loaded just on demand when the
380     respective program change arrives (to safe RAM space), as well as a
381     global volume factor for each entry, so the user can adjust the volume
382     dynamic of his mapped instrument collection without having to modify
383 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
384     MIDI instrument maps and assign each sampler channel individually
385     a certain map, so that i.e. separation of normal instruments and
386     drumkits is possible
387 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
388     MIDI instrument maps, MIDI instruments, FX sends, global volume.
389 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
390     due to a constant size RingBuffer FIFO which is now replaced by a
391     dynamic (unlimited) size std::list FIFO
392 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
393     output channels for being processed by external effect processors
394     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
395     controllers
396 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
397 iliev 1130 - Implemented new, improved notification system
398 schoenebeck 1149 - fixed compilation errors regarding OSX
399     (patch by Toshi Nagata)
400 iliev 1161 - implemented instruments database
401 iliev 1345 - added support for escape sequences to the instruments database
402 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
403     within the sampler's process (by using instrument editor plugins),
404     you'll notice the new "Registered instrument editors:" message on
405 schoenebeck 1407 startup, added a new LSCP command:
406     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
407 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
408     given sampler channel, the plugin path can be overridden at compile
409     time with ./configure --enable-plugin-dir=/some/dir
410 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
411     in the sampler's process to safely edit instruments while playing
412     without a crash (hopefully) by either suspending single regions
413     wherever possible or if unavoidable whole engine(s)
414 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
415     policy and priority on thread level, set a minimum stack size for
416     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
417     threads simply inherited properties of starting thread instead of
418     setting their own policy and priority
419 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
420     main process did not wait for the stack trace process to finish
421     its output
422 persson 1248 - fixed some minor memory leaks
423 schoenebeck 1259 - reenabled assembly features support, at the moment only for
424     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
425 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
426     register, to avoid relocations in the text segment at runtime)
427 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
428 schoenebeck 947
429     * MIDI driver:
430     - dispatch bank select (MSB and LSB) messages
431    
432 schoenebeck 1049 * audio driver:
433     - the ALSA audio output driver parameters now reflect the correct
434     parameter value ranges for the respective selected sound card
435     (patch by Till Wimmer, a bit fixed and extended)
436    
437 persson 951 * Gigasampler format engine:
438     - if a filter is used and EG2 finishes before EG1, let the voice
439     die when EG2 has finished (this fixes a problem with clicks and
440     voice starvation for some gigs)
441 persson 1038 - playback is no longer disabled during instrument loading
442     - all notes playing on a channel that changes its instrument keep
443     playing with the old instrument until they get a note off
444     command
445 persson 1039 - EG fix: a release value of zero could cause noises or crash
446 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
447 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
448     above max sustain level, which means that there is a decay phase
449     even if sustain is 100%
450 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
451     noises or crashes
452 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
453 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
454     supplied to the configure script (fixes #46)
455 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
456     instead of a fix value
457 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
458     127 (solo mode) only kill voices if the respective mode really
459     changed
460 persson 951
461 schoenebeck 1244 * LSCP server:
462     - fixed compile time error for old Bison versions
463     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
464 schoenebeck 1245 - parser now supports extended ASCII character set
465     (up to ASCII code 255, i.e. includes now umlauts and accents)
466     - filename arguments in LSCP commands now allow to use escape
467     sequences, that is directly literal as one of: \', \", \\, \n, \r,
468     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
469     code value like \xf2) (fixes bug #24)
470 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
471     least one of their text-based parameters (i.e. name, description):
472     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
473     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
474     "SET DB_INSTRUMENT_DIRECTORY NAME",
475     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
476     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
477     "FIND DB_INSTRUMENT_DIRECTORIES"
478 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
479     occured, the unexpected character and the actually expected, possible
480     character(s), the latter only if less than 5 possibilities)
481 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
482     settings
483 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
484     of strings were treated as being one string containing commas
485     (fixes #57)
486 schoenebeck 1244
487 iliev 959 * Bug fixes:
488     - fixed crash occurring on certain LSCP scripts (Bug 39)
489 persson 1038 - another thread safety fix for lscp "load engine" and "set
490     channel audio output device"
491 iliev 1283 - fixed a crash which occurs when reassigning the same engine
492     on a sampler channel with connected MIDI device
493 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
494     device connected to a sampler channel to number less then or equal
495     to the index of the port to which the sampler channel is connected.
496 iliev 1296 - The previous bindings were not been disconnected when altering
497     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
498     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
499 iliev 1297 - The active stream/voice count statistic was incorrect.
500 iliev 1298 - notification events were not been sent for some sampler
501     channel changes
502 iliev 1305 - added default min and max values to restrict the number of allowed
503     audio output channels and MIDI input ports
504 iliev 1306 - the connection to the PCM interface is now closed when destroying
505     an audio output device
506 schoenebeck 1332 - files with slash in their path or filename could not be loaded
507 iliev 959
508 schoenebeck 1221 * test cases:
509     - updated and fixed (haven't been touched in a while)
510    
511 schoenebeck 937 Version 0.4.0 (24 November 2006)
512 persson 696
513 schoenebeck 697 * packaging changes:
514 capela 868 - changed deprecated copyright attribute to license; added ldconfig
515     to post-(un)install steps; added devel package for liblinuxsampler;
516     to linuxsampler.spec (RPM)
517 schoenebeck 697 - install necessary development header files for allowing 3rd party
518     applications to link against liblinuxsampler
519     - liblinuxsampler's API documentation can be generated with 'make docs'
520     (Doxygen required)
521 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
522     implementation (currently either an integer math solution or a
523     di-harmonic approximation), automatic detection can be overriden
524     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
525     configure script argument though (mandatory for cross-compilation)
526 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
527     provided some on his own (as CXXFLAGS)
528 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
529     messages
530 schoenebeck 852 - added compile time options to allow disabling the various audio and
531     MIDI drivers
532 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
533     (patch by Ebrahim Mayat)
534 schoenebeck 697
535 persson 696 * Gigasampler format engine:
536 schoenebeck 738 - extensive synthesis optimization
537     (reimplementation of EGs and LFO(s), removed synthesis parameter
538     prerendering and the synthesis parameter matrix in general, splitting
539     each audio fragment into subfragments now where each subfragment uses
540 persson 830 constant pitch and filter coefficients. The volume coefficient is
541     linearly interpolated inside a subfragment, unless
542     --disable-interpolate-volume is set.)
543 persson 696 - fine tuning of the EG modulation parameters
544 persson 729 - improved filter cutoff calculation by adding support for the
545     following gig parameters: Cutoff freq (used when no cutoff
546     controller is defined), Control invert, Minimum cutoff, Velocity
547 persson 791 curve and Velocity range. The keyboard tracking now scales
548     cutoff frequency instead of resonance.
549 persson 877 - added support for gig parameter Resonance.
550 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
551 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
552     which can be overridden with --enable-global-attenuation
553 persson 783 - EG fixes: made the length of "attack hold" stage more
554     accurate. Release stage can now start before attack stage
555 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
556     time now has a minimal value to prevent clicks.
557 persson 799 - fixed pitch changes larger than one octave
558 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
559     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
560     all modes can be altered via standard GM messages, that is CC5 for
561     altering portamento time, CC65 for enabling / disabling portamento
562     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
563 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
564     parameter) and crossfade
565 persson 831 - added support for the "attenuation controller threshold" gig
566     parameter
567 persson 832 - added smoothing of volume changes caused by control change
568     messages
569 persson 865 - sample loop parameters are now taken from the DimensionRegion
570     instead of the wave chunk
571     - fixed keyswitching for v3 gigs with a number of keyswitch splits
572     not equal to a power of two
573 persson 877 - reimplementation of the filter algorithm. The new filter is more
574     accurate and supports all gig filter types, including bandreject
575     and lowpass turbo.
576 persson 903 - real support for 24 bit samples - samples are not truncated to
577     16 bits anymore
578     - support for aftertouch (channel pressure, not polyphonic
579     aftertouch)
580 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
581     amplifying from 0)
582 persson 696
583 schoenebeck 711 * LSCP server:
584     - fixed application exit on broken pipe error (fixes bug #20)
585 iliev 793 - fixed the notification messages delay due to lack of
586     network activity (fixes bug #26)
587 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
588     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
589 schoenebeck 711
590 schoenebeck 838 * audio driver:
591     - added aRts audio output driver (by no means RT safe)
592    
593 schoenebeck 775 * MIDI driver:
594     - fixed legacy sysex code which caused dispatching of MIDI SysEx
595     messages several times instead of once
596 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
597     for events (i.e. for offline rendering based MIDI drivers)
598 persson 922 - added checks for bad MIDI data
599 schoenebeck 775
600 schoenebeck 900 * linuxsampler application:
601     - show available sampler engine types on startup
602    
603 schoenebeck 705 * general changes:
604     - support for muting sampler channels and solo mode of the same, two new
605     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
606     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
607     introduced for this, the behavior is the same like on a mixer console
608 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
609     --enable-process-muted-channels which can be used to enable the
610     processing of muted channels.
611 iliev 777 - support for sostenuto pedal
612 iliev 779 - support for monitoring the total number of active voices
613 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
614     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
615 persson 835 - fixed some memory management errors
616 persson 841 - fixed some concurrency problems that could lead to crashes when
617     LSCP commands were executed
618 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
619     sampler channel (fixes bug #36)
620 schoenebeck 705
621 schoenebeck 692 Version 0.3.3 (15 July 2005)
622 schoenebeck 686
623     * packaging changes:
624     - fixed compilation with gcc 4.0
625    
626 schoenebeck 687 * Gigasampler format engine:
627     - LFO preprocessing was performed even though the respective LFO was
628     disabled by the instrument patch (minor efficiency fix)
629 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
630     for volume ramp downs in the same fragment (needed for current voice
631     stealing implementation) then simply inform the user with a warning
632     about possible click sounds and reduce the volume ramp down
633     appropriately instead of cancelling the audio device connection
634 schoenebeck 687
635 schoenebeck 677 Version 0.3.2 (24 June 2005)
636 schoenebeck 609
637     * packaging changes:
638     - updated autotools build files to compile on OS X
639     (conditional compilation of CoreMIDI and MidiShare drivers)
640 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
641     './configure --disable-asm' (definitely not recommended)
642 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
643     - require automake (>= 1.5) for 'make -f Makefile.cvs'
644     (due to 'dist-bzip2' automake option)
645 schoenebeck 649
646     * Gigasampler format engine:
647     - support for the gig parameters for "release velocity response" curves
648     - fine tuning of the EGADSR envelope
649     - volume of release triggered samples now depends on note-on velocity,
650     note length and gig parameter "release trigger decay" instead of
651     note-off velocity.
652 schoenebeck 663 - revised voice stealing
653     (fixes crash and endless loop caused by voice stealing)
654 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
655 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
656     instead of when the respective voice is actually launched
657     (fixes undefined behavior if stolen voices belonged to a key group -
658     this case was followed by a "killed voice survived" error message)
659 schoenebeck 669 - fixed minor issue with null/silence samples
660     (those stole voices even though they don't need a voice at all which
661     resulted in "voice stealing didn't work out" messages)
662 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
663     instrument or audio output device change
664 schoenebeck 654
665 schoenebeck 620 * LSCP server:
666 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
667 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
668 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
669 schoenebeck 609
670 schoenebeck 668 * linuxsampler application:
671     - added command line parameters --lscp-addr and --lscp-port to override
672     default IP address and port of LSCP server
673    
674 schoenebeck 579 Version 0.3.1 (24 May 2005)
675    
676     * initial release
