1 schoenebeck 1993 Version CVS HEAD (?)
2    
3 persson 2086 * packaging changes:
4     - fixed building with newer MinGW-w64
5    
6     * general changes:
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
13     where the sampler shall look for instrument editor plugins
14     (patch by Luis Garrido, slightly modified).
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
33     multiple regions
34     - added some opcode aliases, like loopmode for loop_mode, to be
35     more compatible
36 persson 2061 - added support for trigger=release and rt_decay
37 persson 2063 - added support for off_mode=normal

47 iliev 2012
48 schoenebeck 2047 * SoundFont format engine:
49 iliev 2012 - Initial implementation (not usable yet)
50    
51     * Host plugins:

53 iliev 1994 - Listen to all interfaces on Mac OS X (INADDR_ANY)
54 persson 2045 - VST bugfix: If the host called resume() before and after
55     changing sample rate or block size, the number of channels was
56     incorrectly set to two. This caused silence in Cubase 5.
57 schoenebeck 1993
58     * MIDI driver:

70 schoenebeck 1599
71 schoenebeck 1639 * packaging changes:
72     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

90 schoenebeck 1639
91 schoenebeck 1601 * general changes:

96     plugin DLL on Windows systems failed
97 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded

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

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

133 schoenebeck 1599 * audio driver:
134     - removed the nonsense audio channel constraint (which was hard coded to
135     max. 100 audio channels) for most audio drivers
136 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
137     opposed to the LSCP specs
138 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
139     reflected the wrong value
140 persson 1644 - fixed a memory management bug in ASIO driver
141 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used
142 persson 1777 - JACK: use jack_client_open instead of the deprecated
143 persson 1748 jack_client_new
144 iliev 1829 - added (experimental) CoreAudio driver
145 persson 1888 - applied old fixes to the ASIO driver that were included in the
146     previous binary release but accidentally never committed to CVS
147     (fixes #117)
148 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
149     win64)
150 persson 1895 - VST: added support for sample rate and buffer size changes
151     - VST: close editor (Fantasia) when the VST is removed

159 schoenebeck 1930 - performance optimization of AudioChannel::MixTo() and
160     AudioChannel::CopyTo() methods using GCC vector exensions
161     (if available)
162 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
163     exception when getting parameters from a disconnected device
164 schoenebeck 1599
165 persson 1651 * MIDI driver:
166     - added JACK MIDI driver
167 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
168     want to (mis)use it for some purpose ("fixed" in all current MIDI
169     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
170 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
171 persson 1887 CoreMidi or AU
172 persson 1889 - fixed mingw-w64 compilation error in MME driver
173 persson 1924 - made program change handling in MIDI thread real-time safe by
174     moving the logic to a non-RT thread

176 persson 1651
177 schoenebeck 1604 * instruments database:
178 iliev 1603 - avoid time consuming samples scanning when adding instruments
179     to the instruments database
180 iliev 1727 - added support for handling lost files in the instruments database

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