* fixed crash when deleting a sampler channel or changing engine type
  while an instrument load was in progress

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 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
16     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
17     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
18     note (in this implementation of the sampler its simply hard routed to
19     the 1st effect send of the sampler channel, no matter what the actual
20     effect type is)
21     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
22     note (in this implementation of the sampler its simply hard routed to
23     the 2nd effect send of the sampler channel, no matter what the actual
24     effect type is)
25 schoenebeck 2124 - implemented support for internal LADSPA effects
26 iliev 2012
27 persson 2043 * Gigasampler format engine:
28     - implemented the "round robin keyboard" dimension
29     - fixed round robin and random dimensions for cases when number of
30     dimension zones is not a power of two
31     - made round robin use a counter for each region instead of each
32     key
33    
34 schoenebeck 2047 * SFZ format engine:
35 iliev 2012 - Initial implementation (not usable yet)
36 persson 2055 - added support for v2 multiple stage envelope generators
37     - added a fine-tuned v1 envelope generator instead of using the
38     one from the gig engine
39 persson 2058 - fixed memory leak and memory handling errors
40 persson 2061 - added support for trigger=first, trigger=legato and sw_previous
41 persson 2058 - allow non-numerical key values ("C#4" for example)
42     - "key" opcode now sets pitch_keycenter too
43     - fixed error when unloading instrument with same sample used by
44     multiple regions
45     - added some opcode aliases, like loopmode for loop_mode, to be
46     more compatible
47 persson 2061 - added support for trigger=release and rt_decay
48 persson 2063 - added support for off_mode=normal
49 persson 2072 - added support for random, seq_position, seq_length and volume
50     - added v1 LFO opcodes to parser (no support in engine yet)
51 persson 2082 - added support for amp_veltrack and amp_velcurve_N
52     - fine-tuned the default velocity curve

57 persson 2091 - reduced memory usage for sfz data
58 persson 2101 - RT-safeness: avoid malloc in audio thread
59     - fixed a bug that could cause voice stealing to fail
60 persson 2106 - optimized sample lookup
61 persson 2114 - improved support for exclusive groups (group, off_by and
62     off_mode)
63 persson 2115 - added support for controller triggered regions (on_locc/on_hicc)
64     - added support for loop_mode=one_shot
65 persson 2119 - fixed playback of 16 bit wav files on big endian CPUs
66     - added support for Ogg Vorbis sample files
67 iliev 2012

75 iliev 1994 - Listen to all interfaces on Mac OS X (INADDR_ANY)
76 persson 2045 - VST bugfix: If the host called resume() before and after
77     changing sample rate or block size, the number of channels was
78     incorrectly set to two. This caused silence in Cubase 5.
79 schoenebeck 1993
80     * MIDI driver:
81     - ALSA MIDI driver supports now "NAME" device parameter, for overriding
82     the ALSA sequencer client name

97 schoenebeck 1599
98 schoenebeck 1639 * packaging changes:
99     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
100     causing e.g. the libgig test to fail when
101     "./configure --disable-jack-driver" was used

117 schoenebeck 1639
118 schoenebeck 1601 * general changes:
119     - bugfix: on some POSIX systems instrument editor plugins refused to
120     load as we used a non-portable Linux specific struct field
121     (fixes bug #70, patch by Ronald Baljeu)
122 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
123     plugin DLL on Windows systems failed
124 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded

126     unnecessarily long after an update
127 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
128     events (e.g. to highlight the pressed keys on the virtual keyboard
129     of gigedit)
130 schoenebeck 1659 - added support for triggering notes by instrument editors (see above)
131 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
132 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation

134     implementation, which is usually faster)
135 persson 1748 - fixes for audio drivers with varying buffer sizes
136 persson 1777 - experimental support for running LinuxSampler as a DSSI, LV2 and
137     VST plugin

142 schoenebeck 1800 - maximum voices and disk streams can now be altered at runtime
143 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
144 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
145     be switched on by command line option "--stacktrace" (the automatic
146     stacktrace mechanism seems to be broken on most systems at the moment)
147 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
148     a pointer to the launched InstrumentEditor object
149 schoenebeck 1876 - added optional 3rd party user data parameter for following
150     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
151     InstrumentEditor::Launch(),

160 schoenebeck 1599 * audio driver:
161     - removed the nonsense audio channel constraint (which was hard coded to
162     max. 100 audio channels) for most audio drivers
163 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
164     opposed to the LSCP specs
165 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
166     reflected the wrong value

170 persson 1748 jack_client_new
171 iliev 1829 - added (experimental) CoreAudio driver
172 persson 1888 - applied old fixes to the ASIO driver that were included in the
173     previous binary release but accidentally never committed to CVS
174     (fixes #117)
175 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
176     win64)
177 persson 1895 - VST: added support for sample rate and buffer size changes
178     - VST: close editor (Fantasia) when the VST is removed

187     AudioChannel::CopyTo() methods using GCC vector exensions
188     (if available)
189 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
190     exception when getting parameters from a disconnected device
191 schoenebeck 1599
192 persson 1651 * MIDI driver:
193     - added JACK MIDI driver
194 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
195     want to (mis)use it for some purpose ("fixed" in all current MIDI
196     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
197 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
198 persson 1887 CoreMidi or AU
199 persson 1889 - fixed mingw-w64 compilation error in MME driver
200 persson 1924 - made program change handling in MIDI thread real-time safe by
201     moving the logic to a non-RT thread

211 persson 1908 - work-around for missing fnmatch function on Windows to make
212     instrument database compilable
213 schoenebeck 1930 - added instrument database support on Windows
214     works with both standalone mode and VST plugin.
215     the instruments DB file is located in
216     %USERPROFILE%\.linuxsampler\instruments.db which allows different
217     databases for each windows user
218     if no DB is present it automatically creates the .linuxsampler subdir
219     and then creates an empty DB
220 persson 1943 - fixed recursive import, which was broken on Windows
221 iliev 1603
222 persson 1644 * Gigasampler format engine:
223     - fixed a memory leak that could happen when a channel was deleted
224     while notes were playing
225 persson 1646 - made it possible to load an instrument even if the audio thread
226     isn't running
227 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
228     enough for piano gigs with pedal noise samples
229 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
230     respective FX send MIDI controller was used
231 schoenebeck 1724 - added support for GM global device volume SysEx message
232 schoenebeck 1762 (can be selected at compile time to either apply globally to the
233     whole sampler [default] or only to the sampler channels that are
234     connected to the respective MIDI input port the SysEx message arrived
235     on)
236 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
237     sometimes wrongly killed in the same buffer, causing no sound to
238     be played
239 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
240     which is usally used to switch a part between chromatic sounds and
241     drumkit sounds (as opposed to their common default setting of MIDI
242     part 10 being a drumkit part and all other ones chromatic parts), in
243     LS however one can switch between the first 16 MIDI instrument maps
244     defined for the sampler
245 persson 1764 - made it possible to create multiple sample channels even if the
246     audio thread isn't running
247 persson 1844 - fixed crash when removing channel with active voices (#116)
248 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
249     un-cache the respective sample if it's really not used by any
250     sampler engine anymore
251     - re-cache samples in case they were changed by an instrument editor,
252     e.g. when a sample was added while playing (#82)
253 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
254     same time stamp as the voice's note-on event and occured both in the
255     same audio fragment cycle (fixes bug #112)
256 persson 1858 - added support for the "fine tune" and "pitch bend range"
257     instrument-level gig parameters
258     - fixed minor artifacts in pitch bend handling
259 schoenebeck 1860 - added support for GS Reset SysEx message
260 persson 1862 - allow gig files to use unlimited downward pitch shifting
261     - added a limit check for upward pitch shifting
262 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
263     note was silent
264 persson 1923 - fixed crash happening when a pitch bend event arrived at the
265     same time a new instrument was loading
266 persson 1644
267 schoenebeck 1687 * LSCP server:
268     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
269     react on MIDI data arriving on certain sampler channels (so far only
270     Note-On and Note-Off events are sent via this LSCP event)
271 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
272     react on MIDI data arriving on certain MIDI input devices (so far only
273     Note-On and Note-Off events are sent via this LSCP event)
274 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
275     SET DB_INSTRUMENT FILE_PATH
276 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
277     frontends to send MIDI messages to specific sampler channel
278     - added two additional fields to GET FILE INSTRUMENT INFO command -
279     KEY_BINDINGS and KEYSWITCH_BINDINGS
280 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
281     was incorrect
282 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
283 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
284     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
285     be triggered respectively
286     - added new LSCP command "SET STREAMS" to globally alter the maximum
287     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
288     which will be triggered respectively
289 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
290     a gigedit file dialog is opened)
291 iliev 1848 - close all connections when LSCPServer is deleted
292 iliev 1882 - hard close of all sockets on exit
293 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
294     driver
295 schoenebeck 1687
296 iliev 1761 * Bug fixes:
297     - fixed a crash which occurs when removing a sampler channel waiting
298     to start instrument loading after another channel
299 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
300     instrument loading in progress (bug #113)
301 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
302     instrument with PERSISTENT load mode
303 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
304     - fixed memory leaks when issuing the following LSCP commands:
305     GET AUDIO_OUTPUT_DRIVER INFO
306     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
307     GET MIDI_INPUT_DRIVER INFO
308     GET MIDI_INPUT_DRIVER_PARAMETER INFO
309     - fixed possible compilation error when sqlite is not present
310 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
311 iliev 1847 - fixed crash when changing the audio output device of a sampler
312     channel with loaded instrument and start playing notes
313 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
314 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
315     PowerPC, which probably could cause crashes on that platform
316 persson 1889 - fixed a memory management error which could cause a crash when a
317     plugin was unloaded
318 persson 1896 - bugfix: two private structs had the same name, which could cause
319     problems if the linker chose the wrong constructor
320 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
321     Windows
322 iliev 1761
323    
324 schoenebeck 1560 Version 0.5.1 (6 December 2007)
325 schoenebeck 1454
326     * packaging changes:
327     - added autoconf checks for pthread library
328     - added autoconf check for pthread bug found on certain NPTL-enabled
329     glibc versions (see Gentoo bug report #194076)
330 senoner 1502 - added autoconf checks for MS Windows
331 schoenebeck 1454
332 persson 1455 * general changes:
333     - bugfix: the thread used by an editor plugin didn't die when the
334     editor closed
335 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
336     out all the space. operator--() did not apply size_mask after
337     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
338     order to avoid problems with the _NonVolatileReader functions.
339     - bugfix: Stream.h: added a missing divide by BytesPerSample in
340     GetWriteSpace(). Since this function is currently only used in
341     the stream's qsort() compare function, it didn't trigger any
342     bugs.
343     - Resampler.h, Synthesizer.h: cubic interpolation now works in
344     24bit mode too. Faster method to read 24bit words on little
345     endian machines (x86): replaced 3 byte reads + shifts with a 1
346     unaligned 32bit read and shift
347     - experimental support for MS Windows (MIDI input via MME, AUDIO
348     output via ASIO)
349     - made handling of SIGINT signal (Ctrl-C) a bit more robust
350 iliev 1541 - support for monitoring the total number of active disk streams
351     (new LSCP commands: GET TOTAL_STREAM_COUNT,
352     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
353 persson 1455
354 senoner 1500 * AUDIO driver:
355 persson 1534 - added Windows ASIO low latency audio driver
356 senoner 1500
357 senoner 1485 * MIDI driver:
358 schoenebeck 1495 - added MME Windows MIDI driver
359 senoner 1485
360 schoenebeck 1471 * LSCP server:
361     - added support for Windows style path / filenames, however with
362     forward slash path separators instead of backslash
363     (i.e. "C:/foo/bar.gig")
364 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
365     apostrophes as well
366 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
367     "LIST FILE INSTRUMENTS <file>" and
368     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
369     about an arbitrary instrument file on the system where the sampler is
370     running on
371 schoenebeck 1471
372 schoenebeck 1424 Version 0.5.0 (15 October 2007)
373 schoenebeck 947
374 schoenebeck 1065 * packaging changes:
375 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
376     API header files anymore
377 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
378     the Doxygen API documentation (explicitly listed in Doxyfile.in)
379 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
380     capable to execute our autoconf environment, thus no need anymore
381     to maintain the compile time configuration file (osx/version.h) for
382     OSX manually (patch by Toshi Nagata)
383 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
384     parameters
385 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
386     C++ API header files, all implementation internal global definitions
387     are now in global_private.h
388     - atomic.h is not exposed to the C++ API anymore
389     - no need to include config.h anymore for using LS's API header files
390     - fixed warnings in API doc generation
391 schoenebeck 1065
392 schoenebeck 947 * general changes:
393     - replaced the old, confusing MIDI program change mechanism by a
394     flexible MIDI instrument mapper which allows to map arbitrary
395 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
396 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
397     loaded on the respective channel when such MIDI program change
398     messages arrive, beside that, each entry allows to define a life-time
399     strategy for the instrument, so the user can define whether the
400     instrument should i.e. be permanently loaded (to be able to switch
401     quickly among sounds) or i.e. loaded just on demand when the
402     respective program change arrives (to safe RAM space), as well as a
403     global volume factor for each entry, so the user can adjust the volume
404     dynamic of his mapped instrument collection without having to modify
405 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
406     MIDI instrument maps and assign each sampler channel individually
407     a certain map, so that i.e. separation of normal instruments and
408     drumkits is possible
409 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
410     MIDI instrument maps, MIDI instruments, FX sends, global volume.
411 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
412     due to a constant size RingBuffer FIFO which is now replaced by a
413     dynamic (unlimited) size std::list FIFO
414 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
415     output channels for being processed by external effect processors
416     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
417     controllers
418 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
419 iliev 1130 - Implemented new, improved notification system
420 schoenebeck 1149 - fixed compilation errors regarding OSX
421     (patch by Toshi Nagata)
422 iliev 1161 - implemented instruments database
423 iliev 1345 - added support for escape sequences to the instruments database
424 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
425     within the sampler's process (by using instrument editor plugins),
426     you'll notice the new "Registered instrument editors:" message on
427 schoenebeck 1407 startup, added a new LSCP command:
428     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
429 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
430     given sampler channel, the plugin path can be overridden at compile
431     time with ./configure --enable-plugin-dir=/some/dir
432 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
433     in the sampler's process to safely edit instruments while playing
434     without a crash (hopefully) by either suspending single regions
435     wherever possible or if unavoidable whole engine(s)
436 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
437     policy and priority on thread level, set a minimum stack size for
438     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
439     threads simply inherited properties of starting thread instead of
440     setting their own policy and priority
441 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
442     main process did not wait for the stack trace process to finish
443     its output
444 persson 1248 - fixed some minor memory leaks
445 schoenebeck 1259 - reenabled assembly features support, at the moment only for
446     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
447 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
448     register, to avoid relocations in the text segment at runtime)
449 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
450 schoenebeck 947
451     * MIDI driver:
452     - dispatch bank select (MSB and LSB) messages
453    
454 schoenebeck 1049 * audio driver:
455     - the ALSA audio output driver parameters now reflect the correct
456     parameter value ranges for the respective selected sound card
457     (patch by Till Wimmer, a bit fixed and extended)
458    
459 persson 951 * Gigasampler format engine:
460     - if a filter is used and EG2 finishes before EG1, let the voice
461     die when EG2 has finished (this fixes a problem with clicks and
462     voice starvation for some gigs)
463 persson 1038 - playback is no longer disabled during instrument loading
464     - all notes playing on a channel that changes its instrument keep
465     playing with the old instrument until they get a note off
466     command
467 persson 1039 - EG fix: a release value of zero could cause noises or crash
468 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
469 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
470     above max sustain level, which means that there is a decay phase
471     even if sustain is 100%
472 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
473     noises or crashes
474 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
475 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
476     supplied to the configure script (fixes #46)
477 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
478     instead of a fix value
479 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
480     127 (solo mode) only kill voices if the respective mode really
481     changed
482 persson 951
483 schoenebeck 1244 * LSCP server:
484     - fixed compile time error for old Bison versions
485     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
486 schoenebeck 1245 - parser now supports extended ASCII character set
487     (up to ASCII code 255, i.e. includes now umlauts and accents)
488     - filename arguments in LSCP commands now allow to use escape
489     sequences, that is directly literal as one of: \', \", \\, \n, \r,
490     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
491     code value like \xf2) (fixes bug #24)
492 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
493     least one of their text-based parameters (i.e. name, description):
494     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
495     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
496     "SET DB_INSTRUMENT_DIRECTORY NAME",
497     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
498     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
499     "FIND DB_INSTRUMENT_DIRECTORIES"
500 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
501     occured, the unexpected character and the actually expected, possible
502     character(s), the latter only if less than 5 possibilities)
503 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
504     settings
505 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
506     of strings were treated as being one string containing commas
507     (fixes #57)
508 schoenebeck 1244
509 iliev 959 * Bug fixes:
510     - fixed crash occurring on certain LSCP scripts (Bug 39)
511 persson 1038 - another thread safety fix for lscp "load engine" and "set
512     channel audio output device"
513 iliev 1283 - fixed a crash which occurs when reassigning the same engine
514     on a sampler channel with connected MIDI device
515 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
516     device connected to a sampler channel to number less then or equal
517     to the index of the port to which the sampler channel is connected.
518 iliev 1296 - The previous bindings were not been disconnected when altering
519     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
520     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
521 iliev 1297 - The active stream/voice count statistic was incorrect.
522 iliev 1298 - notification events were not been sent for some sampler
523     channel changes
524 iliev 1305 - added default min and max values to restrict the number of allowed
525     audio output channels and MIDI input ports
526 iliev 1306 - the connection to the PCM interface is now closed when destroying
527     an audio output device
528 schoenebeck 1332 - files with slash in their path or filename could not be loaded
529 iliev 959
530 schoenebeck 1221 * test cases:
531     - updated and fixed (haven't been touched in a while)
532    
533 schoenebeck 937 Version 0.4.0 (24 November 2006)
534 persson 696
535 schoenebeck 697 * packaging changes:
536 capela 868 - changed deprecated copyright attribute to license; added ldconfig
537     to post-(un)install steps; added devel package for liblinuxsampler;
538     to linuxsampler.spec (RPM)
539 schoenebeck 697 - install necessary development header files for allowing 3rd party
540     applications to link against liblinuxsampler
541     - liblinuxsampler's API documentation can be generated with 'make docs'
542     (Doxygen required)
543 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
544     implementation (currently either an integer math solution or a
545     di-harmonic approximation), automatic detection can be overriden
546     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
547     configure script argument though (mandatory for cross-compilation)
548 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
549     provided some on his own (as CXXFLAGS)
550 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
551     messages
552 schoenebeck 852 - added compile time options to allow disabling the various audio and
553     MIDI drivers
554 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
555     (patch by Ebrahim Mayat)
556 schoenebeck 697
557 persson 696 * Gigasampler format engine:
558 schoenebeck 738 - extensive synthesis optimization
559     (reimplementation of EGs and LFO(s), removed synthesis parameter
560     prerendering and the synthesis parameter matrix in general, splitting
561     each audio fragment into subfragments now where each subfragment uses
562 persson 830 constant pitch and filter coefficients. The volume coefficient is
563     linearly interpolated inside a subfragment, unless
564     --disable-interpolate-volume is set.)
565 persson 696 - fine tuning of the EG modulation parameters
566 persson 729 - improved filter cutoff calculation by adding support for the
567     following gig parameters: Cutoff freq (used when no cutoff
568     controller is defined), Control invert, Minimum cutoff, Velocity
569 persson 791 curve and Velocity range. The keyboard tracking now scales
570     cutoff frequency instead of resonance.
571 persson 877 - added support for gig parameter Resonance.
572 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
573 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
574     which can be overridden with --enable-global-attenuation
575 persson 783 - EG fixes: made the length of "attack hold" stage more
576     accurate. Release stage can now start before attack stage
577 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
578     time now has a minimal value to prevent clicks.
579 persson 799 - fixed pitch changes larger than one octave
580 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
581     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
582     all modes can be altered via standard GM messages, that is CC5 for
583     altering portamento time, CC65 for enabling / disabling portamento
584     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
585 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
586     parameter) and crossfade
587 persson 831 - added support for the "attenuation controller threshold" gig
588     parameter
589 persson 832 - added smoothing of volume changes caused by control change
590     messages
591 persson 865 - sample loop parameters are now taken from the DimensionRegion
592     instead of the wave chunk
593     - fixed keyswitching for v3 gigs with a number of keyswitch splits
594     not equal to a power of two
595 persson 877 - reimplementation of the filter algorithm. The new filter is more
596     accurate and supports all gig filter types, including bandreject
597     and lowpass turbo.
598 persson 903 - real support for 24 bit samples - samples are not truncated to
599     16 bits anymore
600     - support for aftertouch (channel pressure, not polyphonic
601     aftertouch)
602 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
603     amplifying from 0)
604 persson 696
605 schoenebeck 711 * LSCP server:
606     - fixed application exit on broken pipe error (fixes bug #20)
607 iliev 793 - fixed the notification messages delay due to lack of
608     network activity (fixes bug #26)
609 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
610     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
611 schoenebeck 711
612 schoenebeck 838 * audio driver:
613     - added aRts audio output driver (by no means RT safe)
614    
615 schoenebeck 775 * MIDI driver:
616     - fixed legacy sysex code which caused dispatching of MIDI SysEx
617     messages several times instead of once
618 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
619     for events (i.e. for offline rendering based MIDI drivers)
620 persson 922 - added checks for bad MIDI data
621 schoenebeck 775
622 schoenebeck 900 * linuxsampler application:
623     - show available sampler engine types on startup
624    
625 schoenebeck 705 * general changes:
626     - support for muting sampler channels and solo mode of the same, two new
627     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
628     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
629     introduced for this, the behavior is the same like on a mixer console
630 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
631     --enable-process-muted-channels which can be used to enable the
632     processing of muted channels.
633 iliev 777 - support for sostenuto pedal
634 iliev 779 - support for monitoring the total number of active voices
635 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
636     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
637 persson 835 - fixed some memory management errors
638 persson 841 - fixed some concurrency problems that could lead to crashes when
639     LSCP commands were executed
640 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
641     sampler channel (fixes bug #36)
642 schoenebeck 705
643 schoenebeck 692 Version 0.3.3 (15 July 2005)
644 schoenebeck 686
645     * packaging changes:
646     - fixed compilation with gcc 4.0
647    
648 schoenebeck 687 * Gigasampler format engine:
649     - LFO preprocessing was performed even though the respective LFO was
650     disabled by the instrument patch (minor efficiency fix)
651 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
652     for volume ramp downs in the same fragment (needed for current voice
653     stealing implementation) then simply inform the user with a warning
654     about possible click sounds and reduce the volume ramp down
655     appropriately instead of cancelling the audio device connection
656 schoenebeck 687
657 schoenebeck 677 Version 0.3.2 (24 June 2005)
658 schoenebeck 609
659     * packaging changes:
660     - updated autotools build files to compile on OS X
661     (conditional compilation of CoreMIDI and MidiShare drivers)
662 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
663     './configure --disable-asm' (definitely not recommended)
664 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
665     - require automake (>= 1.5) for 'make -f Makefile.cvs'
666     (due to 'dist-bzip2' automake option)
667 schoenebeck 649
668     * Gigasampler format engine:
669     - support for the gig parameters for "release velocity response" curves
670     - fine tuning of the EGADSR envelope
671     - volume of release triggered samples now depends on note-on velocity,
672     note length and gig parameter "release trigger decay" instead of
673     note-off velocity.
674 schoenebeck 663 - revised voice stealing
675     (fixes crash and endless loop caused by voice stealing)
676 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
677 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
678     instead of when the respective voice is actually launched
679     (fixes undefined behavior if stolen voices belonged to a key group -
680     this case was followed by a "killed voice survived" error message)
681 schoenebeck 669 - fixed minor issue with null/silence samples
682     (those stole voices even though they don't need a voice at all which
683     resulted in "voice stealing didn't work out" messages)
684 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
685     instrument or audio output device change
686 schoenebeck 654
687 schoenebeck 620 * LSCP server:
688 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
689 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
690 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
691 schoenebeck 609
692 schoenebeck 668 * linuxsampler application:
693     - added command line parameters --lscp-addr and --lscp-port to override
694     default IP address and port of LSCP server
695    
696 schoenebeck 579 Version 0.3.1 (24 May 2005)
697    
698     * initial release
