* bugfix: playing a note while changing the instrument could cause a
  crash, or give "Handing back unknown region" error messages

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 schoenebeck 2140 - raised limit of program change queue from 100 to 512
27     (as suggested by Alex Stone)
28 iliev 2012
29 persson 2043 * Gigasampler format engine:
30     - implemented the "round robin keyboard" dimension
31     - fixed round robin and random dimensions for cases when number of
32     dimension zones is not a power of two
33     - made round robin use a counter for each region instead of each
34     key
35    
36 schoenebeck 2047 * SFZ format engine:
37 iliev 2012 - Initial implementation (not usable yet)
38 persson 2055 - added support for v2 multiple stage envelope generators
39     - added a fine-tuned v1 envelope generator instead of using the
40     one from the gig engine
41 persson 2058 - fixed memory leak and memory handling errors
42 persson 2061 - added support for trigger=first, trigger=legato and sw_previous
43 persson 2058 - allow non-numerical key values ("C#4" for example)
44     - "key" opcode now sets pitch_keycenter too
45     - fixed error when unloading instrument with same sample used by
46     multiple regions
47     - added some opcode aliases, like loopmode for loop_mode, to be
48     more compatible
49 persson 2061 - added support for trigger=release and rt_decay
50 persson 2063 - added support for off_mode=normal
51 persson 2072 - added support for random, seq_position, seq_length and volume

57     - improved logic for sw_lokey/hikey/up/down/last
58     - added more v1 aliases to parser
59 persson 2091 - reduced memory usage for sfz data
60 persson 2101 - RT-safeness: avoid malloc in audio thread
61     - fixed a bug that could cause voice stealing to fail
62 persson 2106 - optimized sample lookup
63 persson 2114 - improved support for exclusive groups (group, off_by and
64     off_mode)
65 persson 2115 - added support for controller triggered regions (on_locc/on_hicc)
66     - added support for loop_mode=one_shot
67 persson 2119 - fixed playback of 16 bit wav files on big endian CPUs

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

133 schoenebeck 1599
134 schoenebeck 1639 * packaging changes:
135     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
136     causing e.g. the libgig test to fail when
137     "./configure --disable-jack-driver" was used
138     (patch by Alexis Ballier)

153 schoenebeck 1639
154 schoenebeck 1601 * general changes:
155     - bugfix: on some POSIX systems instrument editor plugins refused to
156     load as we used a non-portable Linux specific struct field
157     (fixes bug #70, patch by Ronald Baljeu)
158 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
159     plugin DLL on Windows systems failed
160 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded

166 schoenebeck 1659 - added support for triggering notes by instrument editors (see above)
167 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
168 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation

171 persson 1748 - fixes for audio drivers with varying buffer sizes
172 persson 1777 - experimental support for running LinuxSampler as a DSSI, LV2 and
173     VST plugin

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

189 persson 1887 - theoretical fix: made SynchronizedConfig follow C++0x memory
190     model more strictly
191 persson 1895 - fixes for using large audio device buffers
192 persson 1951 - Windows: add the installation directory to the DLL search path

195 schoenebeck 1601
196 schoenebeck 1599 * audio driver:
197     - removed the nonsense audio channel constraint (which was hard coded to
198     max. 100 audio channels) for most audio drivers
199 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
200     opposed to the LSCP specs
201 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
202     reflected the wrong value
203 persson 1644 - fixed a memory management bug in ASIO driver
204 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used
205 persson 1777 - JACK: use jack_client_open instead of the deprecated
206 persson 1748 jack_client_new
207 iliev 1829 - added (experimental) CoreAudio driver
208 persson 1888 - applied old fixes to the ASIO driver that were included in the
209     previous binary release but accidentally never committed to CVS
210     (fixes #117)
211 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
212     win64)
213 persson 1895 - VST: added support for sample rate and buffer size changes
214     - VST: close editor (Fantasia) when the VST is removed

223     AudioChannel::CopyTo() methods using GCC vector exensions
224     (if available)
225 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
226     exception when getting parameters from a disconnected device
227 schoenebeck 1599
228 persson 1651 * MIDI driver:
229     - added JACK MIDI driver
230 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
231     want to (mis)use it for some purpose ("fixed" in all current MIDI
232     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
233 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
234 persson 1887 CoreMidi or AU
235 persson 1889 - fixed mingw-w64 compilation error in MME driver
236 persson 1924 - made program change handling in MIDI thread real-time safe by
237     moving the logic to a non-RT thread
238 persson 1951 - fixed minor memory leak in ALSA driver
239 persson 1651
240 schoenebeck 1604 * instruments database:
241 iliev 1603 - avoid time consuming samples scanning when adding instruments
242     to the instruments database
243 iliev 1727 - added support for handling lost files in the instruments database
244 iliev 1781 - Implemented option for adding instruments in separate directories
245     in the instruments database
246     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
247 persson 1908 - work-around for missing fnmatch function on Windows to make
248     instrument database compilable
249 schoenebeck 1930 - added instrument database support on Windows
250     works with both standalone mode and VST plugin.
251     the instruments DB file is located in
252     %USERPROFILE%\.linuxsampler\instruments.db which allows different
253     databases for each windows user
254     if no DB is present it automatically creates the .linuxsampler subdir
255     and then creates an empty DB
256 persson 1943 - fixed recursive import, which was broken on Windows
257 iliev 1603
258 persson 1644 * Gigasampler format engine:
259     - fixed a memory leak that could happen when a channel was deleted
260     while notes were playing
261 persson 1646 - made it possible to load an instrument even if the audio thread
262     isn't running
263 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
264     enough for piano gigs with pedal noise samples
265 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
266     respective FX send MIDI controller was used
267 schoenebeck 1724 - added support for GM global device volume SysEx message
268 schoenebeck 1762 (can be selected at compile time to either apply globally to the
269     whole sampler [default] or only to the sampler channels that are
270     connected to the respective MIDI input port the SysEx message arrived
271     on)
272 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
273     sometimes wrongly killed in the same buffer, causing no sound to
274     be played
275 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
276     which is usally used to switch a part between chromatic sounds and
277     drumkit sounds (as opposed to their common default setting of MIDI
278     part 10 being a drumkit part and all other ones chromatic parts), in
279     LS however one can switch between the first 16 MIDI instrument maps
280     defined for the sampler
281 persson 1764 - made it possible to create multiple sample channels even if the
282     audio thread isn't running
283 persson 1844 - fixed crash when removing channel with active voices (#116)
284 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
285     un-cache the respective sample if it's really not used by any
286     sampler engine anymore
287     - re-cache samples in case they were changed by an instrument editor,
288     e.g. when a sample was added while playing (#82)
289 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
290     same time stamp as the voice's note-on event and occured both in the
291     same audio fragment cycle (fixes bug #112)
292 persson 1858 - added support for the "fine tune" and "pitch bend range"
293     instrument-level gig parameters
294     - fixed minor artifacts in pitch bend handling
295 schoenebeck 1860 - added support for GS Reset SysEx message
296 persson 1862 - allow gig files to use unlimited downward pitch shifting
297     - added a limit check for upward pitch shifting
298 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
299     note was silent
300 persson 1923 - fixed crash happening when a pitch bend event arrived at the
301     same time a new instrument was loading
302 persson 1644
303 schoenebeck 1687 * LSCP server:
304     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
305     react on MIDI data arriving on certain sampler channels (so far only
306     Note-On and Note-Off events are sent via this LSCP event)
307 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
308     react on MIDI data arriving on certain MIDI input devices (so far only
309     Note-On and Note-Off events are sent via this LSCP event)
310 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
311     SET DB_INSTRUMENT FILE_PATH
312 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
313     frontends to send MIDI messages to specific sampler channel
314     - added two additional fields to GET FILE INSTRUMENT INFO command -
315     KEY_BINDINGS and KEYSWITCH_BINDINGS
316 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
317     was incorrect
318 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
319 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
320     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
321     be triggered respectively
322     - added new LSCP command "SET STREAMS" to globally alter the maximum
323     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
324     which will be triggered respectively
325 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
326     a gigedit file dialog is opened)
327 iliev 1848 - close all connections when LSCPServer is deleted
328 iliev 1882 - hard close of all sockets on exit
329 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
330     driver
331 schoenebeck 1687
332 iliev 1761 * Bug fixes:
333     - fixed a crash which occurs when removing a sampler channel waiting
334     to start instrument loading after another channel

336     instrument loading in progress (bug #113)
337 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
338     instrument with PERSISTENT load mode
339 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
340     - fixed memory leaks when issuing the following LSCP commands:
341     GET AUDIO_OUTPUT_DRIVER INFO
342     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
343     GET MIDI_INPUT_DRIVER INFO
344     GET MIDI_INPUT_DRIVER_PARAMETER INFO
345     - fixed possible compilation error when sqlite is not present
346 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
347 iliev 1847 - fixed crash when changing the audio output device of a sampler
348     channel with loaded instrument and start playing notes
349 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
350 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
351     PowerPC, which probably could cause crashes on that platform
352 persson 1889 - fixed a memory management error which could cause a crash when a
353     plugin was unloaded
354 persson 1896 - bugfix: two private structs had the same name, which could cause

360 schoenebeck 1560 Version 0.5.1 (6 December 2007)
361 schoenebeck 1454
362     * packaging changes:
363     - added autoconf checks for pthread library
364     - added autoconf check for pthread bug found on certain NPTL-enabled
365     glibc versions (see Gentoo bug report #194076)
366 senoner 1502 - added autoconf checks for MS Windows
367 schoenebeck 1454
368 persson 1455 * general changes:
369     - bugfix: the thread used by an editor plugin didn't die when the
370     editor closed
371 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
372     out all the space. operator--() did not apply size_mask after
373     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
374     order to avoid problems with the _NonVolatileReader functions.
375     - bugfix: Stream.h: added a missing divide by BytesPerSample in
376     GetWriteSpace(). Since this function is currently only used in
377     the stream's qsort() compare function, it didn't trigger any
378     bugs.
379     - Resampler.h, Synthesizer.h: cubic interpolation now works in
380     24bit mode too. Faster method to read 24bit words on little
381     endian machines (x86): replaced 3 byte reads + shifts with a 1
382     unaligned 32bit read and shift
383     - experimental support for MS Windows (MIDI input via MME, AUDIO
384     output via ASIO)
385     - made handling of SIGINT signal (Ctrl-C) a bit more robust
386 iliev 1541 - support for monitoring the total number of active disk streams
387     (new LSCP commands: GET TOTAL_STREAM_COUNT,
388     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
389 persson 1455
390 senoner 1500 * AUDIO driver:
391 persson 1534 - added Windows ASIO low latency audio driver
392 senoner 1500
393 senoner 1485 * MIDI driver:
394 schoenebeck 1495 - added MME Windows MIDI driver
395 senoner 1485
396 schoenebeck 1471 * LSCP server:
397     - added support for Windows style path / filenames, however with
398     forward slash path separators instead of backslash
399     (i.e. "C:/foo/bar.gig")
400 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
401     apostrophes as well
402 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
403     "LIST FILE INSTRUMENTS <file>" and
404     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
405     about an arbitrary instrument file on the system where the sampler is
406     running on
407 schoenebeck 1471
408 schoenebeck 1424 Version 0.5.0 (15 October 2007)
409 schoenebeck 947
410 schoenebeck 1065 * packaging changes:
411 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
412     API header files anymore
413 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
414     the Doxygen API documentation (explicitly listed in Doxyfile.in)
415 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
416     capable to execute our autoconf environment, thus no need anymore
417     to maintain the compile time configuration file (osx/version.h) for
418     OSX manually (patch by Toshi Nagata)
419 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
420     parameters
421 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
422     C++ API header files, all implementation internal global definitions
423     are now in global_private.h
424     - atomic.h is not exposed to the C++ API anymore
425     - no need to include config.h anymore for using LS's API header files
426     - fixed warnings in API doc generation
427 schoenebeck 1065
428 schoenebeck 947 * general changes:
429     - replaced the old, confusing MIDI program change mechanism by a
430     flexible MIDI instrument mapper which allows to map arbitrary
431 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
432 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
433     loaded on the respective channel when such MIDI program change
434     messages arrive, beside that, each entry allows to define a life-time
435     strategy for the instrument, so the user can define whether the
436     instrument should i.e. be permanently loaded (to be able to switch
437     quickly among sounds) or i.e. loaded just on demand when the
438     respective program change arrives (to safe RAM space), as well as a
439     global volume factor for each entry, so the user can adjust the volume
440     dynamic of his mapped instrument collection without having to modify
441 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
442     MIDI instrument maps and assign each sampler channel individually
443     a certain map, so that i.e. separation of normal instruments and
444     drumkits is possible
445 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
446     MIDI instrument maps, MIDI instruments, FX sends, global volume.
447 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
448     due to a constant size RingBuffer FIFO which is now replaced by a
449     dynamic (unlimited) size std::list FIFO
450 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
451     output channels for being processed by external effect processors
452     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
453     controllers
454 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
455 iliev 1130 - Implemented new, improved notification system
456 schoenebeck 1149 - fixed compilation errors regarding OSX
457     (patch by Toshi Nagata)
458 iliev 1161 - implemented instruments database
459 iliev 1345 - added support for escape sequences to the instruments database
460 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
461     within the sampler's process (by using instrument editor plugins),
462     you'll notice the new "Registered instrument editors:" message on
463 schoenebeck 1407 startup, added a new LSCP command:
464     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
465 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
466     given sampler channel, the plugin path can be overridden at compile
467     time with ./configure --enable-plugin-dir=/some/dir
468 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
469     in the sampler's process to safely edit instruments while playing
470     without a crash (hopefully) by either suspending single regions
471     wherever possible or if unavoidable whole engine(s)
472 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
473     policy and priority on thread level, set a minimum stack size for
474     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
475     threads simply inherited properties of starting thread instead of
476     setting their own policy and priority
477 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
478     main process did not wait for the stack trace process to finish
479     its output
480 persson 1248 - fixed some minor memory leaks
481 schoenebeck 1259 - reenabled assembly features support, at the moment only for
482     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
483 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
484     register, to avoid relocations in the text segment at runtime)
485 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
486 schoenebeck 947
487     * MIDI driver:
488     - dispatch bank select (MSB and LSB) messages
489    
490 schoenebeck 1049 * audio driver:
491     - the ALSA audio output driver parameters now reflect the correct
492     parameter value ranges for the respective selected sound card
493     (patch by Till Wimmer, a bit fixed and extended)
494    
495 persson 951 * Gigasampler format engine:
496     - if a filter is used and EG2 finishes before EG1, let the voice
497     die when EG2 has finished (this fixes a problem with clicks and
498     voice starvation for some gigs)
499 persson 1038 - playback is no longer disabled during instrument loading
500     - all notes playing on a channel that changes its instrument keep
501     playing with the old instrument until they get a note off
502     command
503 persson 1039 - EG fix: a release value of zero could cause noises or crash
504 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
505 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
506     above max sustain level, which means that there is a decay phase
507     even if sustain is 100%
508 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
509     noises or crashes
510 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
511 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
512     supplied to the configure script (fixes #46)
513 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
514     instead of a fix value
515 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
516     127 (solo mode) only kill voices if the respective mode really
517     changed
518 persson 951
519 schoenebeck 1244 * LSCP server:
520     - fixed compile time error for old Bison versions
521     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
522 schoenebeck 1245 - parser now supports extended ASCII character set
523     (up to ASCII code 255, i.e. includes now umlauts and accents)
524     - filename arguments in LSCP commands now allow to use escape
525     sequences, that is directly literal as one of: \', \", \\, \n, \r,
526     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
527     code value like \xf2) (fixes bug #24)
528 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
529     least one of their text-based parameters (i.e. name, description):
530     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
531     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
532     "SET DB_INSTRUMENT_DIRECTORY NAME",
533     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
534     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
535     "FIND DB_INSTRUMENT_DIRECTORIES"
536 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
537     occured, the unexpected character and the actually expected, possible
538     character(s), the latter only if less than 5 possibilities)
539 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
540     settings
541 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
542     of strings were treated as being one string containing commas
543     (fixes #57)
544 schoenebeck 1244
545 iliev 959 * Bug fixes:
546     - fixed crash occurring on certain LSCP scripts (Bug 39)
547 persson 1038 - another thread safety fix for lscp "load engine" and "set
548     channel audio output device"
549 iliev 1283 - fixed a crash which occurs when reassigning the same engine
550     on a sampler channel with connected MIDI device
551 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
552     device connected to a sampler channel to number less then or equal
553     to the index of the port to which the sampler channel is connected.
554 iliev 1296 - The previous bindings were not been disconnected when altering
555     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
556     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
557 iliev 1297 - The active stream/voice count statistic was incorrect.
558 iliev 1298 - notification events were not been sent for some sampler
559     channel changes
560 iliev 1305 - added default min and max values to restrict the number of allowed
561     audio output channels and MIDI input ports
562 iliev 1306 - the connection to the PCM interface is now closed when destroying
563     an audio output device
564 schoenebeck 1332 - files with slash in their path or filename could not be loaded
565 iliev 959
566 schoenebeck 1221 * test cases:
567     - updated and fixed (haven't been touched in a while)
568    
569 schoenebeck 937 Version 0.4.0 (24 November 2006)
570 persson 696
571 schoenebeck 697 * packaging changes:
572 capela 868 - changed deprecated copyright attribute to license; added ldconfig
573     to post-(un)install steps; added devel package for liblinuxsampler;
574     to linuxsampler.spec (RPM)
575 schoenebeck 697 - install necessary development header files for allowing 3rd party
576     applications to link against liblinuxsampler
577     - liblinuxsampler's API documentation can be generated with 'make docs'
578     (Doxygen required)
579 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
580     implementation (currently either an integer math solution or a
581     di-harmonic approximation), automatic detection can be overriden
582     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
583     configure script argument though (mandatory for cross-compilation)
584 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
585     provided some on his own (as CXXFLAGS)
586 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
587     messages
588 schoenebeck 852 - added compile time options to allow disabling the various audio and
589     MIDI drivers
590 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
591     (patch by Ebrahim Mayat)
592 schoenebeck 697
593 persson 696 * Gigasampler format engine:
594 schoenebeck 738 - extensive synthesis optimization
595     (reimplementation of EGs and LFO(s), removed synthesis parameter
596     prerendering and the synthesis parameter matrix in general, splitting
597     each audio fragment into subfragments now where each subfragment uses
598 persson 830 constant pitch and filter coefficients. The volume coefficient is
599     linearly interpolated inside a subfragment, unless
600     --disable-interpolate-volume is set.)
601 persson 696 - fine tuning of the EG modulation parameters
602 persson 729 - improved filter cutoff calculation by adding support for the
603     following gig parameters: Cutoff freq (used when no cutoff
604     controller is defined), Control invert, Minimum cutoff, Velocity
605 persson 791 curve and Velocity range. The keyboard tracking now scales
606     cutoff frequency instead of resonance.
607 persson 877 - added support for gig parameter Resonance.
608 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
609 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
610     which can be overridden with --enable-global-attenuation
611 persson 783 - EG fixes: made the length of "attack hold" stage more
612     accurate. Release stage can now start before attack stage
613 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
614     time now has a minimal value to prevent clicks.
615 persson 799 - fixed pitch changes larger than one octave
616 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
617     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
618     all modes can be altered via standard GM messages, that is CC5 for
619     altering portamento time, CC65 for enabling / disabling portamento
620     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
621 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
622     parameter) and crossfade
623 persson 831 - added support for the "attenuation controller threshold" gig
624     parameter
625 persson 832 - added smoothing of volume changes caused by control change
626     messages
627 persson 865 - sample loop parameters are now taken from the DimensionRegion
628     instead of the wave chunk
629     - fixed keyswitching for v3 gigs with a number of keyswitch splits
630     not equal to a power of two
631 persson 877 - reimplementation of the filter algorithm. The new filter is more
632     accurate and supports all gig filter types, including bandreject
633     and lowpass turbo.
634 persson 903 - real support for 24 bit samples - samples are not truncated to
635     16 bits anymore
636     - support for aftertouch (channel pressure, not polyphonic
637     aftertouch)
638 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
639     amplifying from 0)
640 persson 696
641 schoenebeck 711 * LSCP server:
642     - fixed application exit on broken pipe error (fixes bug #20)
643 iliev 793 - fixed the notification messages delay due to lack of
644     network activity (fixes bug #26)
645 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
646     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
647 schoenebeck 711
648 schoenebeck 838 * audio driver:
649     - added aRts audio output driver (by no means RT safe)
650    
651 schoenebeck 775 * MIDI driver:
652     - fixed legacy sysex code which caused dispatching of MIDI SysEx
653     messages several times instead of once
654 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
655     for events (i.e. for offline rendering based MIDI drivers)
656 persson 922 - added checks for bad MIDI data
657 schoenebeck 775
658 schoenebeck 900 * linuxsampler application:
659     - show available sampler engine types on startup
660    
661 schoenebeck 705 * general changes:
662     - support for muting sampler channels and solo mode of the same, two new
663     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
664     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
665     introduced for this, the behavior is the same like on a mixer console
666 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
667     --enable-process-muted-channels which can be used to enable the
668     processing of muted channels.
669 iliev 777 - support for sostenuto pedal
670 iliev 779 - support for monitoring the total number of active voices
671 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
672     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
673 persson 835 - fixed some memory management errors
674 persson 841 - fixed some concurrency problems that could lead to crashes when
675     LSCP commands were executed
676 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
677     sampler channel (fixes bug #36)
678 schoenebeck 705
679 schoenebeck 692 Version 0.3.3 (15 July 2005)
680 schoenebeck 686
681     * packaging changes:
682     - fixed compilation with gcc 4.0
683    
684 schoenebeck 687 * Gigasampler format engine:
685     - LFO preprocessing was performed even though the respective LFO was
686     disabled by the instrument patch (minor efficiency fix)
687 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
688     for volume ramp downs in the same fragment (needed for current voice
689     stealing implementation) then simply inform the user with a warning
690     about possible click sounds and reduce the volume ramp down
691     appropriately instead of cancelling the audio device connection
692 schoenebeck 687
693 schoenebeck 677 Version 0.3.2 (24 June 2005)
694 schoenebeck 609
695     * packaging changes:
696     - updated autotools build files to compile on OS X
697     (conditional compilation of CoreMIDI and MidiShare drivers)
698 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
699     './configure --disable-asm' (definitely not recommended)
700 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
701     - require automake (>= 1.5) for 'make -f Makefile.cvs'
702     (due to 'dist-bzip2' automake option)
703 schoenebeck 649
704     * Gigasampler format engine:
705     - support for the gig parameters for "release velocity response" curves
706     - fine tuning of the EGADSR envelope
707     - volume of release triggered samples now depends on note-on velocity,
708     note length and gig parameter "release trigger decay" instead of
709     note-off velocity.
710 schoenebeck 663 - revised voice stealing
711     (fixes crash and endless loop caused by voice stealing)
712 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
713 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
714     instead of when the respective voice is actually launched
715     (fixes undefined behavior if stolen voices belonged to a key group -
716     this case was followed by a "killed voice survived" error message)
717 schoenebeck 669 - fixed minor issue with null/silence samples
718     (those stole voices even though they don't need a voice at all which
719     resulted in "voice stealing didn't work out" messages)
720 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
721     instrument or audio output device change
722 schoenebeck 654
723 schoenebeck 620 * LSCP server:
724 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
725 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
726 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
727 schoenebeck 609
728 schoenebeck 668 * linuxsampler application:
729     - added command line parameters --lscp-addr and --lscp-port to override
730     default IP address and port of LSCP server
731    
732 schoenebeck 579 Version 0.3.1 (24 May 2005)
733    
734     * initial release
