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

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

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 persson 2165 - save engine type (gig, sfz or sf2) in plugin state

134 persson 2165 - bugfix: calling SET VOICES (which Fantasia does on start and
135     refresh) could cause instruments to be unloaded
136 iliev 2012

138 schoenebeck 1599
139 schoenebeck 1639 * packaging changes:
140     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
141     causing e.g. the libgig test to fail when
142     "./configure --disable-jack-driver" was used

158 schoenebeck 1639
159 schoenebeck 1601 * general changes:
160     - bugfix: on some POSIX systems instrument editor plugins refused to

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

175     implementation, which is usually faster)
176 persson 1748 - fixes for audio drivers with varying buffer sizes
177 persson 1777 - experimental support for running LinuxSampler as a DSSI, LV2 and
178     VST plugin

185 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
186     be switched on by command line option "--stacktrace" (the automatic
187     stacktrace mechanism seems to be broken on most systems at the moment)
188 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
189     a pointer to the launched InstrumentEditor object
190 schoenebeck 1876 - added optional 3rd party user data parameter for following
191     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
192     InstrumentEditor::Launch(),

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

224     stereo
225 persson 1922 - added channel routing, fxsends and midi maps to the settings
226     stored in the plugin state
227 schoenebeck 1930 - performance optimization of AudioChannel::MixTo() and
228     AudioChannel::CopyTo() methods using GCC vector exensions
229     (if available)
230 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
231     exception when getting parameters from a disconnected device
232 schoenebeck 1599
233 persson 1651 * MIDI driver:
234     - added JACK MIDI driver
235 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
236     want to (mis)use it for some purpose ("fixed" in all current MIDI
237     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
238 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
239 persson 1887 CoreMidi or AU
240 persson 1889 - fixed mingw-w64 compilation error in MME driver
241 persson 1924 - made program change handling in MIDI thread real-time safe by
242     moving the logic to a non-RT thread
243 persson 1951 - fixed minor memory leak in ALSA driver
244 persson 1651
245 schoenebeck 1604 * instruments database:
246 iliev 1603 - avoid time consuming samples scanning when adding instruments
247     to the instruments database
248 iliev 1727 - added support for handling lost files in the instruments database
249 iliev 1781 - Implemented option for adding instruments in separate directories
250     in the instruments database
251     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
252 persson 1908 - work-around for missing fnmatch function on Windows to make
253     instrument database compilable
254 schoenebeck 1930 - added instrument database support on Windows
255     works with both standalone mode and VST plugin.
256     the instruments DB file is located in
257     %USERPROFILE%\.linuxsampler\instruments.db which allows different
258     databases for each windows user
259     if no DB is present it automatically creates the .linuxsampler subdir
260     and then creates an empty DB
261 persson 1943 - fixed recursive import, which was broken on Windows
262 iliev 1603
263 persson 1644 * Gigasampler format engine:
264     - fixed a memory leak that could happen when a channel was deleted
265     while notes were playing
266 persson 1646 - made it possible to load an instrument even if the audio thread
267     isn't running
268 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
269     enough for piano gigs with pedal noise samples
270 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
271     respective FX send MIDI controller was used
272 schoenebeck 1724 - added support for GM global device volume SysEx message
273 schoenebeck 1762 (can be selected at compile time to either apply globally to the
274     whole sampler [default] or only to the sampler channels that are
275     connected to the respective MIDI input port the SysEx message arrived
276     on)
277 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
278     sometimes wrongly killed in the same buffer, causing no sound to
279     be played
280 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
281     which is usally used to switch a part between chromatic sounds and
282     drumkit sounds (as opposed to their common default setting of MIDI
283     part 10 being a drumkit part and all other ones chromatic parts), in
284     LS however one can switch between the first 16 MIDI instrument maps
285     defined for the sampler
286 persson 1764 - made it possible to create multiple sample channels even if the
287     audio thread isn't running
288 persson 1844 - fixed crash when removing channel with active voices (#116)
289 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
290     un-cache the respective sample if it's really not used by any
291     sampler engine anymore
292     - re-cache samples in case they were changed by an instrument editor,
293     e.g. when a sample was added while playing (#82)
294 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
295     same time stamp as the voice's note-on event and occured both in the
296     same audio fragment cycle (fixes bug #112)
297 persson 1858 - added support for the "fine tune" and "pitch bend range"
298     instrument-level gig parameters
299     - fixed minor artifacts in pitch bend handling
300 schoenebeck 1860 - added support for GS Reset SysEx message
301 persson 1862 - allow gig files to use unlimited downward pitch shifting
302     - added a limit check for upward pitch shifting
303 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
304     note was silent
305 persson 1923 - fixed crash happening when a pitch bend event arrived at the
306     same time a new instrument was loading
307 persson 1644
308 schoenebeck 1687 * LSCP server:
309     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
310     react on MIDI data arriving on certain sampler channels (so far only
311     Note-On and Note-Off events are sent via this LSCP event)
312 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
313     react on MIDI data arriving on certain MIDI input devices (so far only
314     Note-On and Note-Off events are sent via this LSCP event)
315 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
316     SET DB_INSTRUMENT FILE_PATH
317 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
318     frontends to send MIDI messages to specific sampler channel
319     - added two additional fields to GET FILE INSTRUMENT INFO command -
320     KEY_BINDINGS and KEYSWITCH_BINDINGS
321 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
322     was incorrect
323 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
324 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
325     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
326     be triggered respectively
327     - added new LSCP command "SET STREAMS" to globally alter the maximum
328     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
329     which will be triggered respectively
330 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
331     a gigedit file dialog is opened)
332 iliev 1848 - close all connections when LSCPServer is deleted
333 iliev 1882 - hard close of all sockets on exit
334 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
335     driver
336 schoenebeck 1687
337 iliev 1761 * Bug fixes:
338     - fixed a crash which occurs when removing a sampler channel waiting
339     to start instrument loading after another channel

341     instrument loading in progress (bug #113)
342 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
343     instrument with PERSISTENT load mode
344 iliev 1835 - fixed possible iterator invalidations when resetting the sampler

347     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
348     GET MIDI_INPUT_DRIVER INFO
349     GET MIDI_INPUT_DRIVER_PARAMETER INFO
350     - fixed possible compilation error when sqlite is not present
351 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
352 iliev 1847 - fixed crash when changing the audio output device of a sampler
353     channel with loaded instrument and start playing notes
354 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
355 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
356     PowerPC, which probably could cause crashes on that platform
357 persson 1889 - fixed a memory management error which could cause a crash when a
358     plugin was unloaded
359 persson 1896 - bugfix: two private structs had the same name, which could cause

365 schoenebeck 1560 Version 0.5.1 (6 December 2007)
366 schoenebeck 1454
367     * packaging changes:
368     - added autoconf checks for pthread library
369     - added autoconf check for pthread bug found on certain NPTL-enabled
370     glibc versions (see Gentoo bug report #194076)
371 senoner 1502 - added autoconf checks for MS Windows
372 schoenebeck 1454
373 persson 1455 * general changes:
374     - bugfix: the thread used by an editor plugin didn't die when the
375     editor closed
376 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
377     out all the space. operator--() did not apply size_mask after
378     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
379     order to avoid problems with the _NonVolatileReader functions.
380     - bugfix: Stream.h: added a missing divide by BytesPerSample in
381     GetWriteSpace(). Since this function is currently only used in
382     the stream's qsort() compare function, it didn't trigger any
383     bugs.
384     - Resampler.h, Synthesizer.h: cubic interpolation now works in
385     24bit mode too. Faster method to read 24bit words on little
386     endian machines (x86): replaced 3 byte reads + shifts with a 1
387     unaligned 32bit read and shift
388     - experimental support for MS Windows (MIDI input via MME, AUDIO
389     output via ASIO)
390     - made handling of SIGINT signal (Ctrl-C) a bit more robust
391 iliev 1541 - support for monitoring the total number of active disk streams
392     (new LSCP commands: GET TOTAL_STREAM_COUNT,
393     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
394 persson 1455
395 senoner 1500 * AUDIO driver:
396 persson 1534 - added Windows ASIO low latency audio driver
397 senoner 1500
398 senoner 1485 * MIDI driver:
399 schoenebeck 1495 - added MME Windows MIDI driver
400 senoner 1485
401 schoenebeck 1471 * LSCP server:
402     - added support for Windows style path / filenames, however with
403     forward slash path separators instead of backslash
404     (i.e. "C:/foo/bar.gig")
405 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
406     apostrophes as well
407 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
408     "LIST FILE INSTRUMENTS <file>" and
409     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
410     about an arbitrary instrument file on the system where the sampler is
411     running on
412 schoenebeck 1471
413 schoenebeck 1424 Version 0.5.0 (15 October 2007)
414 schoenebeck 947
415 schoenebeck 1065 * packaging changes:
416 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
417     API header files anymore
418 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
419     the Doxygen API documentation (explicitly listed in Doxyfile.in)
420 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
421     capable to execute our autoconf environment, thus no need anymore
422     to maintain the compile time configuration file (osx/version.h) for
423     OSX manually (patch by Toshi Nagata)
424 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
425     parameters
426 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
427     C++ API header files, all implementation internal global definitions
428     are now in global_private.h
429     - atomic.h is not exposed to the C++ API anymore
430     - no need to include config.h anymore for using LS's API header files
431     - fixed warnings in API doc generation
432 schoenebeck 1065
433 schoenebeck 947 * general changes:
434     - replaced the old, confusing MIDI program change mechanism by a
435     flexible MIDI instrument mapper which allows to map arbitrary
436 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
437 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
438     loaded on the respective channel when such MIDI program change
439     messages arrive, beside that, each entry allows to define a life-time
440     strategy for the instrument, so the user can define whether the
441     instrument should i.e. be permanently loaded (to be able to switch
442     quickly among sounds) or i.e. loaded just on demand when the
443     respective program change arrives (to safe RAM space), as well as a
444     global volume factor for each entry, so the user can adjust the volume
445     dynamic of his mapped instrument collection without having to modify
446 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
447     MIDI instrument maps and assign each sampler channel individually
448     a certain map, so that i.e. separation of normal instruments and
449     drumkits is possible
450 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
451     MIDI instrument maps, MIDI instruments, FX sends, global volume.
452 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
453     due to a constant size RingBuffer FIFO which is now replaced by a
454     dynamic (unlimited) size std::list FIFO
455 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
456     output channels for being processed by external effect processors
457     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
458     controllers
459 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
460 iliev 1130 - Implemented new, improved notification system
461 schoenebeck 1149 - fixed compilation errors regarding OSX
462     (patch by Toshi Nagata)
463 iliev 1161 - implemented instruments database
464 iliev 1345 - added support for escape sequences to the instruments database
465 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
466     within the sampler's process (by using instrument editor plugins),
467     you'll notice the new "Registered instrument editors:" message on
468 schoenebeck 1407 startup, added a new LSCP command:
469     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
470 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
471     given sampler channel, the plugin path can be overridden at compile
472     time with ./configure --enable-plugin-dir=/some/dir
473 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
474     in the sampler's process to safely edit instruments while playing
475     without a crash (hopefully) by either suspending single regions
476     wherever possible or if unavoidable whole engine(s)
477 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
478     policy and priority on thread level, set a minimum stack size for
479     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
480     threads simply inherited properties of starting thread instead of
481     setting their own policy and priority
482 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
483     main process did not wait for the stack trace process to finish
484     its output
485 persson 1248 - fixed some minor memory leaks
486 schoenebeck 1259 - reenabled assembly features support, at the moment only for
487     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
488 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
489     register, to avoid relocations in the text segment at runtime)
490 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
491 schoenebeck 947
492     * MIDI driver:
493     - dispatch bank select (MSB and LSB) messages
494    
495 schoenebeck 1049 * audio driver:
496     - the ALSA audio output driver parameters now reflect the correct
497     parameter value ranges for the respective selected sound card
498     (patch by Till Wimmer, a bit fixed and extended)
499    
500 persson 951 * Gigasampler format engine:
501     - if a filter is used and EG2 finishes before EG1, let the voice
502     die when EG2 has finished (this fixes a problem with clicks and
503     voice starvation for some gigs)
504 persson 1038 - playback is no longer disabled during instrument loading
505     - all notes playing on a channel that changes its instrument keep
506     playing with the old instrument until they get a note off
507     command
508 persson 1039 - EG fix: a release value of zero could cause noises or crash
509 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
510 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
511     above max sustain level, which means that there is a decay phase
512     even if sustain is 100%
513 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
514     noises or crashes
515 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
516 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
517     supplied to the configure script (fixes #46)
518 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
519     instead of a fix value
520 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
521     127 (solo mode) only kill voices if the respective mode really
522     changed
523 persson 951
524 schoenebeck 1244 * LSCP server:
525     - fixed compile time error for old Bison versions
526     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
527 schoenebeck 1245 - parser now supports extended ASCII character set
528     (up to ASCII code 255, i.e. includes now umlauts and accents)
529     - filename arguments in LSCP commands now allow to use escape
530     sequences, that is directly literal as one of: \', \", \\, \n, \r,
531     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
532     code value like \xf2) (fixes bug #24)
533 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
534     least one of their text-based parameters (i.e. name, description):
535     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
536     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
537     "SET DB_INSTRUMENT_DIRECTORY NAME",
538     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
539     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
540     "FIND DB_INSTRUMENT_DIRECTORIES"
541 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
542     occured, the unexpected character and the actually expected, possible
543     character(s), the latter only if less than 5 possibilities)
544 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
545     settings
546 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
547     of strings were treated as being one string containing commas
548     (fixes #57)
549 schoenebeck 1244
550 iliev 959 * Bug fixes:
551     - fixed crash occurring on certain LSCP scripts (Bug 39)
552 persson 1038 - another thread safety fix for lscp "load engine" and "set
553     channel audio output device"
554 iliev 1283 - fixed a crash which occurs when reassigning the same engine
555     on a sampler channel with connected MIDI device
556 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
557     device connected to a sampler channel to number less then or equal
558     to the index of the port to which the sampler channel is connected.
559 iliev 1296 - The previous bindings were not been disconnected when altering
560     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
561     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
562 iliev 1297 - The active stream/voice count statistic was incorrect.
563 iliev 1298 - notification events were not been sent for some sampler
564     channel changes
565 iliev 1305 - added default min and max values to restrict the number of allowed
566     audio output channels and MIDI input ports
567 iliev 1306 - the connection to the PCM interface is now closed when destroying
568     an audio output device
569 schoenebeck 1332 - files with slash in their path or filename could not be loaded
570 iliev 959
571 schoenebeck 1221 * test cases:
572     - updated and fixed (haven't been touched in a while)
573    
574 schoenebeck 937 Version 0.4.0 (24 November 2006)
575 persson 696
576 schoenebeck 697 * packaging changes:
577 capela 868 - changed deprecated copyright attribute to license; added ldconfig
578     to post-(un)install steps; added devel package for liblinuxsampler;
579     to linuxsampler.spec (RPM)
580 schoenebeck 697 - install necessary development header files for allowing 3rd party
581     applications to link against liblinuxsampler
582     - liblinuxsampler's API documentation can be generated with 'make docs'
583     (Doxygen required)
584 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
585     implementation (currently either an integer math solution or a
586     di-harmonic approximation), automatic detection can be overriden
587     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
588     configure script argument though (mandatory for cross-compilation)
589 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
590     provided some on his own (as CXXFLAGS)
591 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
592     messages
593 schoenebeck 852 - added compile time options to allow disabling the various audio and
594     MIDI drivers
595 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
596     (patch by Ebrahim Mayat)
597 schoenebeck 697
598 persson 696 * Gigasampler format engine:
599 schoenebeck 738 - extensive synthesis optimization
600     (reimplementation of EGs and LFO(s), removed synthesis parameter
601     prerendering and the synthesis parameter matrix in general, splitting
602     each audio fragment into subfragments now where each subfragment uses
603 persson 830 constant pitch and filter coefficients. The volume coefficient is
604     linearly interpolated inside a subfragment, unless
605     --disable-interpolate-volume is set.)
606 persson 696 - fine tuning of the EG modulation parameters
607 persson 729 - improved filter cutoff calculation by adding support for the
608     following gig parameters: Cutoff freq (used when no cutoff
609     controller is defined), Control invert, Minimum cutoff, Velocity
610 persson 791 curve and Velocity range. The keyboard tracking now scales
611     cutoff frequency instead of resonance.
612 persson 877 - added support for gig parameter Resonance.
613 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
614 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
615     which can be overridden with --enable-global-attenuation
616 persson 783 - EG fixes: made the length of "attack hold" stage more
617     accurate. Release stage can now start before attack stage
618 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
619     time now has a minimal value to prevent clicks.
620 persson 799 - fixed pitch changes larger than one octave
621 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
622     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
623     all modes can be altered via standard GM messages, that is CC5 for
624     altering portamento time, CC65 for enabling / disabling portamento
625     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
626 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
627     parameter) and crossfade
628 persson 831 - added support for the "attenuation controller threshold" gig
629     parameter
630 persson 832 - added smoothing of volume changes caused by control change
631     messages
632 persson 865 - sample loop parameters are now taken from the DimensionRegion
633     instead of the wave chunk
634     - fixed keyswitching for v3 gigs with a number of keyswitch splits
635     not equal to a power of two
636 persson 877 - reimplementation of the filter algorithm. The new filter is more
637     accurate and supports all gig filter types, including bandreject
638     and lowpass turbo.
639 persson 903 - real support for 24 bit samples - samples are not truncated to
640     16 bits anymore
641     - support for aftertouch (channel pressure, not polyphonic
642     aftertouch)
643 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
644     amplifying from 0)
645 persson 696
646 schoenebeck 711 * LSCP server:
647     - fixed application exit on broken pipe error (fixes bug #20)
648 iliev 793 - fixed the notification messages delay due to lack of
649     network activity (fixes bug #26)
650 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
651     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
652 schoenebeck 711
653 schoenebeck 838 * audio driver:
654     - added aRts audio output driver (by no means RT safe)
655    
656 schoenebeck 775 * MIDI driver:
657     - fixed legacy sysex code which caused dispatching of MIDI SysEx
658     messages several times instead of once
659 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
660     for events (i.e. for offline rendering based MIDI drivers)
661 persson 922 - added checks for bad MIDI data
662 schoenebeck 775
663 schoenebeck 900 * linuxsampler application:
664     - show available sampler engine types on startup
665    
666 schoenebeck 705 * general changes:
667     - support for muting sampler channels and solo mode of the same, two new
668     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
669     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
670     introduced for this, the behavior is the same like on a mixer console
671 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
672     --enable-process-muted-channels which can be used to enable the
673     processing of muted channels.
674 iliev 777 - support for sostenuto pedal
675 iliev 779 - support for monitoring the total number of active voices
676 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
677     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
678 persson 835 - fixed some memory management errors
679 persson 841 - fixed some concurrency problems that could lead to crashes when
680     LSCP commands were executed
681 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
682     sampler channel (fixes bug #36)
683 schoenebeck 705
684 schoenebeck 692 Version 0.3.3 (15 July 2005)
685 schoenebeck 686
686     * packaging changes:
687     - fixed compilation with gcc 4.0
688    
689 schoenebeck 687 * Gigasampler format engine:
690     - LFO preprocessing was performed even though the respective LFO was
691     disabled by the instrument patch (minor efficiency fix)
692 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
693     for volume ramp downs in the same fragment (needed for current voice
694     stealing implementation) then simply inform the user with a warning
695     about possible click sounds and reduce the volume ramp down
696     appropriately instead of cancelling the audio device connection
697 schoenebeck 687
698 schoenebeck 677 Version 0.3.2 (24 June 2005)
699 schoenebeck 609
700     * packaging changes:
701     - updated autotools build files to compile on OS X
702     (conditional compilation of CoreMIDI and MidiShare drivers)
703 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
704     './configure --disable-asm' (definitely not recommended)
705 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
706     - require automake (>= 1.5) for 'make -f Makefile.cvs'
707     (due to 'dist-bzip2' automake option)
708 schoenebeck 649
709     * Gigasampler format engine:
710     - support for the gig parameters for "release velocity response" curves
711     - fine tuning of the EGADSR envelope
712     - volume of release triggered samples now depends on note-on velocity,
713     note length and gig parameter "release trigger decay" instead of
714     note-off velocity.
715 schoenebeck 663 - revised voice stealing
716     (fixes crash and endless loop caused by voice stealing)
717 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
718 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
719     instead of when the respective voice is actually launched
720     (fixes undefined behavior if stolen voices belonged to a key group -
721     this case was followed by a "killed voice survived" error message)
722 schoenebeck 669 - fixed minor issue with null/silence samples
723     (those stole voices even though they don't need a voice at all which
724     resulted in "voice stealing didn't work out" messages)
725 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
726     instrument or audio output device change
727 schoenebeck 654
728 schoenebeck 620 * LSCP server:
729 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
730 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
731 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
732 schoenebeck 609
733 schoenebeck 668 * linuxsampler application:
734     - added command line parameters --lscp-addr and --lscp-port to override
735     default IP address and port of LSCP server
736    
737 schoenebeck 579 Version 0.3.1 (24 May 2005)
738    
739     * initial release
