* fixed crash which occured when changing an already deployed sampler
  channel to a different engine type (e.g. from gig to sf2)
* bumped version to 1.0.0cvs5

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 iliev 2012
26 persson 2043 * Gigasampler format engine:
27     - implemented the "round robin keyboard" dimension
28     - fixed round robin and random dimensions for cases when number of
29     dimension zones is not a power of two
30     - made round robin use a counter for each region instead of each
31     key
32    
33 schoenebeck 2047 * SFZ format engine:
34 iliev 2012 - Initial implementation (not usable yet)
35 persson 2055 - added support for v2 multiple stage envelope generators
36     - added a fine-tuned v1 envelope generator instead of using the
37     one from the gig engine
38 persson 2058 - fixed memory leak and memory handling errors
39 persson 2061 - added support for trigger=first, trigger=legato and sw_previous
40 persson 2058 - allow non-numerical key values ("C#4" for example)
41     - "key" opcode now sets pitch_keycenter too
42     - fixed error when unloading instrument with same sample used by
43     multiple regions
44     - added some opcode aliases, like loopmode for loop_mode, to be
45     more compatible
46 persson 2061 - added support for trigger=release and rt_decay
47 persson 2063 - added support for off_mode=normal
48 persson 2072 - added support for random, seq_position, seq_length and volume
49     - added v1 LFO opcodes to parser (no support in engine yet)

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

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

94 schoenebeck 1599
95 schoenebeck 1639 * packaging changes:
96     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
97     causing e.g. the libgig test to fail when
98     "./configure --disable-jack-driver" was used
99     (patch by Alexis Ballier)

114 schoenebeck 1639
115 schoenebeck 1601 * general changes:
116     - bugfix: on some POSIX systems instrument editor plugins refused to

118     (fixes bug #70, patch by Ronald Baljeu)
119 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
120     plugin DLL on Windows systems failed
121 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded
122     - optimized the SynchronizedConfig class so it doesn't wait
123     unnecessarily long after an update
124 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
125     events (e.g. to highlight the pressed keys on the virtual keyboard
126     of gigedit)
127 schoenebeck 1659 - added support for triggering notes by instrument editors (see above)
128 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
129 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation

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

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

156 schoenebeck 1601
157 schoenebeck 1599 * audio driver:
158     - removed the nonsense audio channel constraint (which was hard coded to
159     max. 100 audio channels) for most audio drivers
160 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
161     opposed to the LSCP specs
162 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
163     reflected the wrong value
164 persson 1644 - fixed a memory management bug in ASIO driver
165 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used
166 persson 1777 - JACK: use jack_client_open instead of the deprecated
167 persson 1748 jack_client_new
168 iliev 1829 - added (experimental) CoreAudio driver
169 persson 1888 - applied old fixes to the ASIO driver that were included in the
170     previous binary release but accidentally never committed to CVS
171     (fixes #117)
172 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
173     win64)
174 persson 1895 - VST: added support for sample rate and buffer size changes
175     - VST: close editor (Fantasia) when the VST is removed
176 persson 1908 - VST: avoid opening Fantasia more than once for each VST instance

183 schoenebeck 1930 - performance optimization of AudioChannel::MixTo() and
184     AudioChannel::CopyTo() methods using GCC vector exensions
185     (if available)
186 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
187     exception when getting parameters from a disconnected device
188 schoenebeck 1599
189 persson 1651 * MIDI driver:
190     - added JACK MIDI driver
191 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
192     want to (mis)use it for some purpose ("fixed" in all current MIDI
193     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
194 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
195 persson 1887 CoreMidi or AU
196 persson 1889 - fixed mingw-w64 compilation error in MME driver
197 persson 1924 - made program change handling in MIDI thread real-time safe by
198     moving the logic to a non-RT thread
199 persson 1951 - fixed minor memory leak in ALSA driver
200 persson 1651
201 schoenebeck 1604 * instruments database:
202 iliev 1603 - avoid time consuming samples scanning when adding instruments
203     to the instruments database
204 iliev 1727 - added support for handling lost files in the instruments database
205 iliev 1781 - Implemented option for adding instruments in separate directories
206     in the instruments database
207     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
208 persson 1908 - work-around for missing fnmatch function on Windows to make
209     instrument database compilable
210 schoenebeck 1930 - added instrument database support on Windows
211     works with both standalone mode and VST plugin.
212     the instruments DB file is located in
213     %USERPROFILE%\.linuxsampler\instruments.db which allows different
214     databases for each windows user
215     if no DB is present it automatically creates the .linuxsampler subdir
216     and then creates an empty DB
217 persson 1943 - fixed recursive import, which was broken on Windows
218 iliev 1603
219 persson 1644 * Gigasampler format engine:
220     - fixed a memory leak that could happen when a channel was deleted
221     while notes were playing
222 persson 1646 - made it possible to load an instrument even if the audio thread
223     isn't running
224 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
225     enough for piano gigs with pedal noise samples
226 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
227     respective FX send MIDI controller was used
228 schoenebeck 1724 - added support for GM global device volume SysEx message
229 schoenebeck 1762 (can be selected at compile time to either apply globally to the
230     whole sampler [default] or only to the sampler channels that are
231     connected to the respective MIDI input port the SysEx message arrived
232     on)
233 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
234     sometimes wrongly killed in the same buffer, causing no sound to
235     be played
236 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
237     which is usally used to switch a part between chromatic sounds and
238     drumkit sounds (as opposed to their common default setting of MIDI
239     part 10 being a drumkit part and all other ones chromatic parts), in
240     LS however one can switch between the first 16 MIDI instrument maps
241     defined for the sampler
242 persson 1764 - made it possible to create multiple sample channels even if the
243     audio thread isn't running
244 persson 1844 - fixed crash when removing channel with active voices (#116)
245 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
246     un-cache the respective sample if it's really not used by any
247     sampler engine anymore
248     - re-cache samples in case they were changed by an instrument editor,
249     e.g. when a sample was added while playing (#82)
250 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
251     same time stamp as the voice's note-on event and occured both in the
252     same audio fragment cycle (fixes bug #112)
253 persson 1858 - added support for the "fine tune" and "pitch bend range"
254     instrument-level gig parameters
255     - fixed minor artifacts in pitch bend handling
256 schoenebeck 1860 - added support for GS Reset SysEx message
257 persson 1862 - allow gig files to use unlimited downward pitch shifting
258     - added a limit check for upward pitch shifting
259 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
260     note was silent
261 persson 1923 - fixed crash happening when a pitch bend event arrived at the
262     same time a new instrument was loading
263 persson 1644
264 schoenebeck 1687 * LSCP server:
265     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
266     react on MIDI data arriving on certain sampler channels (so far only
267     Note-On and Note-Off events are sent via this LSCP event)
268 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
269     react on MIDI data arriving on certain MIDI input devices (so far only
270     Note-On and Note-Off events are sent via this LSCP event)
271 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
272     SET DB_INSTRUMENT FILE_PATH
273 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
274     frontends to send MIDI messages to specific sampler channel
275     - added two additional fields to GET FILE INSTRUMENT INFO command -
276     KEY_BINDINGS and KEYSWITCH_BINDINGS
277 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
278     was incorrect
279 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
280 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
281     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
282     be triggered respectively
283     - added new LSCP command "SET STREAMS" to globally alter the maximum
284     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
285     which will be triggered respectively
286 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
287     a gigedit file dialog is opened)
288 iliev 1848 - close all connections when LSCPServer is deleted
289 iliev 1882 - hard close of all sockets on exit
290 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
291     driver
292 schoenebeck 1687
293 iliev 1761 * Bug fixes:
294     - fixed a crash which occurs when removing a sampler channel waiting
295     to start instrument loading after another channel
296 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
297     instrument loading in progress (bug #113)
298 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
299     instrument with PERSISTENT load mode
300 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
301     - fixed memory leaks when issuing the following LSCP commands:
302     GET AUDIO_OUTPUT_DRIVER INFO
303     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
304     GET MIDI_INPUT_DRIVER INFO
305     GET MIDI_INPUT_DRIVER_PARAMETER INFO
306     - fixed possible compilation error when sqlite is not present
307 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
308 iliev 1847 - fixed crash when changing the audio output device of a sampler
309     channel with loaded instrument and start playing notes
310 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
311 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
312     PowerPC, which probably could cause crashes on that platform
313 persson 1889 - fixed a memory management error which could cause a crash when a
314     plugin was unloaded
315 persson 1896 - bugfix: two private structs had the same name, which could cause
316     problems if the linker chose the wrong constructor
317 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
318     Windows
319 iliev 1761
320    
321 schoenebeck 1560 Version 0.5.1 (6 December 2007)
322 schoenebeck 1454
323     * packaging changes:
324     - added autoconf checks for pthread library
325     - added autoconf check for pthread bug found on certain NPTL-enabled
326     glibc versions (see Gentoo bug report #194076)
327 senoner 1502 - added autoconf checks for MS Windows
328 schoenebeck 1454
329 persson 1455 * general changes:
330     - bugfix: the thread used by an editor plugin didn't die when the
331     editor closed
332 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
333     out all the space. operator--() did not apply size_mask after
334     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
335     order to avoid problems with the _NonVolatileReader functions.
336     - bugfix: Stream.h: added a missing divide by BytesPerSample in
337     GetWriteSpace(). Since this function is currently only used in
338     the stream's qsort() compare function, it didn't trigger any
339     bugs.
340     - Resampler.h, Synthesizer.h: cubic interpolation now works in
341     24bit mode too. Faster method to read 24bit words on little
342     endian machines (x86): replaced 3 byte reads + shifts with a 1
343     unaligned 32bit read and shift
344     - experimental support for MS Windows (MIDI input via MME, AUDIO
345     output via ASIO)
346     - made handling of SIGINT signal (Ctrl-C) a bit more robust
347 iliev 1541 - support for monitoring the total number of active disk streams
348     (new LSCP commands: GET TOTAL_STREAM_COUNT,
349     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
350 persson 1455
351 senoner 1500 * AUDIO driver:
352 persson 1534 - added Windows ASIO low latency audio driver
353 senoner 1500
354 senoner 1485 * MIDI driver:
355 schoenebeck 1495 - added MME Windows MIDI driver
356 senoner 1485
357 schoenebeck 1471 * LSCP server:
358     - added support for Windows style path / filenames, however with
359     forward slash path separators instead of backslash
360     (i.e. "C:/foo/bar.gig")
361 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
362     apostrophes as well
363 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
364     "LIST FILE INSTRUMENTS <file>" and
365     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
366     about an arbitrary instrument file on the system where the sampler is
367     running on
368 schoenebeck 1471
369 schoenebeck 1424 Version 0.5.0 (15 October 2007)
370 schoenebeck 947
371 schoenebeck 1065 * packaging changes:
372 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
373     API header files anymore
374 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
375     the Doxygen API documentation (explicitly listed in Doxyfile.in)
376 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
377     capable to execute our autoconf environment, thus no need anymore
378     to maintain the compile time configuration file (osx/version.h) for
379     OSX manually (patch by Toshi Nagata)
380 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
381     parameters
382 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
383     C++ API header files, all implementation internal global definitions
384     are now in global_private.h
385     - atomic.h is not exposed to the C++ API anymore
386     - no need to include config.h anymore for using LS's API header files
387     - fixed warnings in API doc generation
388 schoenebeck 1065
389 schoenebeck 947 * general changes:
390     - replaced the old, confusing MIDI program change mechanism by a
391     flexible MIDI instrument mapper which allows to map arbitrary
392 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
393 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
394     loaded on the respective channel when such MIDI program change
395     messages arrive, beside that, each entry allows to define a life-time
396     strategy for the instrument, so the user can define whether the
397     instrument should i.e. be permanently loaded (to be able to switch
398     quickly among sounds) or i.e. loaded just on demand when the
399     respective program change arrives (to safe RAM space), as well as a
400     global volume factor for each entry, so the user can adjust the volume
401     dynamic of his mapped instrument collection without having to modify
402 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
403     MIDI instrument maps and assign each sampler channel individually
404     a certain map, so that i.e. separation of normal instruments and
405     drumkits is possible
406 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
407     MIDI instrument maps, MIDI instruments, FX sends, global volume.
408 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
409     due to a constant size RingBuffer FIFO which is now replaced by a
410     dynamic (unlimited) size std::list FIFO
411 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
412     output channels for being processed by external effect processors
413     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
414     controllers
415 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
416 iliev 1130 - Implemented new, improved notification system
417 schoenebeck 1149 - fixed compilation errors regarding OSX
418     (patch by Toshi Nagata)
419 iliev 1161 - implemented instruments database
420 iliev 1345 - added support for escape sequences to the instruments database
421 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
422     within the sampler's process (by using instrument editor plugins),
423     you'll notice the new "Registered instrument editors:" message on
424 schoenebeck 1407 startup, added a new LSCP command:
425     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
426 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
427     given sampler channel, the plugin path can be overridden at compile
428     time with ./configure --enable-plugin-dir=/some/dir
429 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
430     in the sampler's process to safely edit instruments while playing
431     without a crash (hopefully) by either suspending single regions
432     wherever possible or if unavoidable whole engine(s)
433 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
434     policy and priority on thread level, set a minimum stack size for
435     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
436     threads simply inherited properties of starting thread instead of
437     setting their own policy and priority
438 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
439     main process did not wait for the stack trace process to finish
440     its output
441 persson 1248 - fixed some minor memory leaks
442 schoenebeck 1259 - reenabled assembly features support, at the moment only for
443     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
444 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
445     register, to avoid relocations in the text segment at runtime)
446 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
447 schoenebeck 947
448     * MIDI driver:
449     - dispatch bank select (MSB and LSB) messages
450    
451 schoenebeck 1049 * audio driver:
452     - the ALSA audio output driver parameters now reflect the correct
453     parameter value ranges for the respective selected sound card
454     (patch by Till Wimmer, a bit fixed and extended)
455    
456 persson 951 * Gigasampler format engine:
457     - if a filter is used and EG2 finishes before EG1, let the voice
458     die when EG2 has finished (this fixes a problem with clicks and
459     voice starvation for some gigs)
460 persson 1038 - playback is no longer disabled during instrument loading
461     - all notes playing on a channel that changes its instrument keep
462     playing with the old instrument until they get a note off
463     command
464 persson 1039 - EG fix: a release value of zero could cause noises or crash
465 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
466 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
467     above max sustain level, which means that there is a decay phase
468     even if sustain is 100%
469 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
470     noises or crashes
471 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
472 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
473     supplied to the configure script (fixes #46)
474 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
475     instead of a fix value
476 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
477     127 (solo mode) only kill voices if the respective mode really
478     changed
479 persson 951
480 schoenebeck 1244 * LSCP server:
481     - fixed compile time error for old Bison versions
482     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
483 schoenebeck 1245 - parser now supports extended ASCII character set
484     (up to ASCII code 255, i.e. includes now umlauts and accents)
485     - filename arguments in LSCP commands now allow to use escape
486     sequences, that is directly literal as one of: \', \", \\, \n, \r,
487     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
488     code value like \xf2) (fixes bug #24)
489 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
490     least one of their text-based parameters (i.e. name, description):
491     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
492     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
493     "SET DB_INSTRUMENT_DIRECTORY NAME",
494     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
495     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
496     "FIND DB_INSTRUMENT_DIRECTORIES"
497 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
498     occured, the unexpected character and the actually expected, possible
499     character(s), the latter only if less than 5 possibilities)
500 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
501     settings
502 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
503     of strings were treated as being one string containing commas
504     (fixes #57)
505 schoenebeck 1244
506 iliev 959 * Bug fixes:
507     - fixed crash occurring on certain LSCP scripts (Bug 39)
508 persson 1038 - another thread safety fix for lscp "load engine" and "set
509     channel audio output device"
510 iliev 1283 - fixed a crash which occurs when reassigning the same engine
511     on a sampler channel with connected MIDI device
512 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
513     device connected to a sampler channel to number less then or equal
514     to the index of the port to which the sampler channel is connected.
515 iliev 1296 - The previous bindings were not been disconnected when altering
516     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
517     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
518 iliev 1297 - The active stream/voice count statistic was incorrect.
519 iliev 1298 - notification events were not been sent for some sampler
520     channel changes
521 iliev 1305 - added default min and max values to restrict the number of allowed
522     audio output channels and MIDI input ports
523 iliev 1306 - the connection to the PCM interface is now closed when destroying
524     an audio output device
525 schoenebeck 1332 - files with slash in their path or filename could not be loaded
526 iliev 959
527 schoenebeck 1221 * test cases:
528     - updated and fixed (haven't been touched in a while)
529    
530 schoenebeck 937 Version 0.4.0 (24 November 2006)
531 persson 696
532 schoenebeck 697 * packaging changes:
533 capela 868 - changed deprecated copyright attribute to license; added ldconfig
534     to post-(un)install steps; added devel package for liblinuxsampler;
535     to linuxsampler.spec (RPM)
536 schoenebeck 697 - install necessary development header files for allowing 3rd party
537     applications to link against liblinuxsampler
538     - liblinuxsampler's API documentation can be generated with 'make docs'
539     (Doxygen required)
540 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
541     implementation (currently either an integer math solution or a
542     di-harmonic approximation), automatic detection can be overriden
543     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
544     configure script argument though (mandatory for cross-compilation)
545 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
546     provided some on his own (as CXXFLAGS)
547 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
548     messages
549 schoenebeck 852 - added compile time options to allow disabling the various audio and
550     MIDI drivers
551 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
552     (patch by Ebrahim Mayat)
553 schoenebeck 697
554 persson 696 * Gigasampler format engine:
555 schoenebeck 738 - extensive synthesis optimization
556     (reimplementation of EGs and LFO(s), removed synthesis parameter
557     prerendering and the synthesis parameter matrix in general, splitting
558     each audio fragment into subfragments now where each subfragment uses
559 persson 830 constant pitch and filter coefficients. The volume coefficient is
560     linearly interpolated inside a subfragment, unless
561     --disable-interpolate-volume is set.)
562 persson 696 - fine tuning of the EG modulation parameters
563 persson 729 - improved filter cutoff calculation by adding support for the
564     following gig parameters: Cutoff freq (used when no cutoff
565     controller is defined), Control invert, Minimum cutoff, Velocity
566 persson 791 curve and Velocity range. The keyboard tracking now scales
567     cutoff frequency instead of resonance.
568 persson 877 - added support for gig parameter Resonance.
569 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
570 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
571     which can be overridden with --enable-global-attenuation
572 persson 783 - EG fixes: made the length of "attack hold" stage more
573     accurate. Release stage can now start before attack stage
574 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
575     time now has a minimal value to prevent clicks.
576 persson 799 - fixed pitch changes larger than one octave
577 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
578     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
579     all modes can be altered via standard GM messages, that is CC5 for
580     altering portamento time, CC65 for enabling / disabling portamento
581     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
582 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
583     parameter) and crossfade
584 persson 831 - added support for the "attenuation controller threshold" gig
585     parameter
586 persson 832 - added smoothing of volume changes caused by control change
587     messages
588 persson 865 - sample loop parameters are now taken from the DimensionRegion
589     instead of the wave chunk
590     - fixed keyswitching for v3 gigs with a number of keyswitch splits
591     not equal to a power of two
592 persson 877 - reimplementation of the filter algorithm. The new filter is more
593     accurate and supports all gig filter types, including bandreject
594     and lowpass turbo.
595 persson 903 - real support for 24 bit samples - samples are not truncated to
596     16 bits anymore
597     - support for aftertouch (channel pressure, not polyphonic
598     aftertouch)
599 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
600     amplifying from 0)
601 persson 696
602 schoenebeck 711 * LSCP server:
603     - fixed application exit on broken pipe error (fixes bug #20)
604 iliev 793 - fixed the notification messages delay due to lack of
605     network activity (fixes bug #26)
606 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
607     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
608 schoenebeck 711
609 schoenebeck 838 * audio driver:
610     - added aRts audio output driver (by no means RT safe)
611    
612 schoenebeck 775 * MIDI driver:
613     - fixed legacy sysex code which caused dispatching of MIDI SysEx
614     messages several times instead of once
615 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
616     for events (i.e. for offline rendering based MIDI drivers)
617 persson 922 - added checks for bad MIDI data
618 schoenebeck 775
619 schoenebeck 900 * linuxsampler application:
620     - show available sampler engine types on startup
621    
622 schoenebeck 705 * general changes:
623     - support for muting sampler channels and solo mode of the same, two new
624     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
625     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
626     introduced for this, the behavior is the same like on a mixer console
627 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
628     --enable-process-muted-channels which can be used to enable the
629     processing of muted channels.
630 iliev 777 - support for sostenuto pedal
631 iliev 779 - support for monitoring the total number of active voices
632 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
633     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
634 persson 835 - fixed some memory management errors
635 persson 841 - fixed some concurrency problems that could lead to crashes when
636     LSCP commands were executed
637 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
638     sampler channel (fixes bug #36)
639 schoenebeck 705
640 schoenebeck 692 Version 0.3.3 (15 July 2005)
641 schoenebeck 686
642     * packaging changes:
643     - fixed compilation with gcc 4.0
644    
645 schoenebeck 687 * Gigasampler format engine:
646     - LFO preprocessing was performed even though the respective LFO was
647     disabled by the instrument patch (minor efficiency fix)
648 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
649     for volume ramp downs in the same fragment (needed for current voice
650     stealing implementation) then simply inform the user with a warning
651     about possible click sounds and reduce the volume ramp down
652     appropriately instead of cancelling the audio device connection
653 schoenebeck 687
654 schoenebeck 677 Version 0.3.2 (24 June 2005)
655 schoenebeck 609
656     * packaging changes:
657     - updated autotools build files to compile on OS X
658     (conditional compilation of CoreMIDI and MidiShare drivers)
659 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
660     './configure --disable-asm' (definitely not recommended)
661 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
662     - require automake (>= 1.5) for 'make -f Makefile.cvs'
663     (due to 'dist-bzip2' automake option)
664 schoenebeck 649
665     * Gigasampler format engine:
666     - support for the gig parameters for "release velocity response" curves
667     - fine tuning of the EGADSR envelope
668     - volume of release triggered samples now depends on note-on velocity,
669     note length and gig parameter "release trigger decay" instead of
670     note-off velocity.
671 schoenebeck 663 - revised voice stealing
672     (fixes crash and endless loop caused by voice stealing)
673 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
674 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
675     instead of when the respective voice is actually launched
676     (fixes undefined behavior if stolen voices belonged to a key group -
677     this case was followed by a "killed voice survived" error message)
678 schoenebeck 669 - fixed minor issue with null/silence samples
679     (those stole voices even though they don't need a voice at all which
680     resulted in "voice stealing didn't work out" messages)
681 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
682     instrument or audio output device change
683 schoenebeck 654
684 schoenebeck 620 * LSCP server:
685 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
686 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
687 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
688 schoenebeck 609
689 schoenebeck 668 * linuxsampler application:
690     - added command line parameters --lscp-addr and --lscp-port to override
691     default IP address and port of LSCP server
692    
693 schoenebeck 579 Version 0.3.1 (24 May 2005)
694    
695     * initial release
