3 capela 2174 * plugin changes:
4     - LV2 Persist + Files support (patch by David Robillard)
5    
6 persson 2086 * packaging changes:
7     - fixed building with newer MinGW-w64
8    
9     * general changes:
10 iliev 2012 - Refactoring: moved the independent code from
11     the Gigasampler format engine to base classes
12 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
13     respective profiling code is currently broken
14 schoenebeck 2053 - Introduced support for optional environment variable
15     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
16     where the sampler shall look for instrument editor plugins
17     (patch by Luis Garrido, slightly modified).
18 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
19     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
20     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
21     note (in this implementation of the sampler its simply hard routed to
22     the 1st effect send of the sampler channel, no matter what the actual
23     effect type is)
24     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
25     note (in this implementation of the sampler its simply hard routed to
26     the 2nd effect send of the sampler channel, no matter what the actual
27     effect type is)
28 schoenebeck 2124 - implemented support for internal LADSPA effects
29 schoenebeck 2140 - raised limit of program change queue from 100 to 512
30     (as suggested by Alex Stone)

33     - implemented the "round robin keyboard" dimension
34     - fixed round robin and random dimensions for cases when number of
35     dimension zones is not a power of two
36     - made round robin use a counter for each region instead of each
37     key
38    
39 schoenebeck 2047 * SFZ format engine:
40 iliev 2012 - Initial implementation (not usable yet)
41 persson 2055 - added support for v2 multiple stage envelope generators
42     - added a fine-tuned v1 envelope generator instead of using the

45 persson 2061 - added support for trigger=first, trigger=legato and sw_previous
46 persson 2058 - allow non-numerical key values ("C#4" for example)
47     - "key" opcode now sets pitch_keycenter too
48     - fixed error when unloading instrument with same sample used by
49     multiple regions
50     - added some opcode aliases, like loopmode for loop_mode, to be
51     more compatible

65 persson 2106 - optimized sample lookup
66 persson 2114 - improved support for exclusive groups (group, off_by and
67     off_mode)
68 persson 2115 - added support for controller triggered regions (on_locc/on_hicc)
69     - added support for loop_mode=one_shot

83 persson 2045 - VST bugfix: If the host called resume() before and after
84     changing sample rate or block size, the number of channels was
85     incorrectly set to two. This caused silence in Cubase 5.
86 persson 2165 - save engine type (gig, sfz or sf2) in plugin state

137 persson 2162 - bugfix: playing a note while changing the instrument could cause
138     a crash, or give "Handing back unknown region" error messages
139 persson 2165 - bugfix: calling SET VOICES (which Fantasia does on start and
140     refresh) could cause instruments to be unloaded
141 iliev 2012
142 persson 1957 Version 1.0.0 (31 July 2009)
143 schoenebeck 1599
144 schoenebeck 1639 * packaging changes:
145     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

163 schoenebeck 1639
164 schoenebeck 1601 * general changes:
165     - bugfix: on some POSIX systems instrument editor plugins refused to

177 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
178 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation

182 persson 1777 - experimental support for running LinuxSampler as a DSSI, LV2 and
183     VST plugin

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

206 schoenebeck 1599 * audio driver:
207     - removed the nonsense audio channel constraint (which was hard coded to
208     max. 100 audio channels) for most audio drivers
209 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
210     opposed to the LSCP specs
211 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
212     reflected the wrong value
213 persson 1644 - fixed a memory management bug in ASIO driver
214 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used
215 persson 1777 - JACK: use jack_client_open instead of the deprecated
216 persson 1748 jack_client_new
217 iliev 1829 - added (experimental) CoreAudio driver
218 persson 1888 - applied old fixes to the ASIO driver that were included in the
219     previous binary release but accidentally never committed to CVS
220     (fixes #117)
221 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
222     win64)
223 persson 1895 - VST: added support for sample rate and buffer size changes
224     - VST: close editor (Fantasia) when the VST is removed
225 persson 1908 - VST: avoid opening Fantasia more than once for each VST instance

233     AudioChannel::CopyTo() methods using GCC vector exensions
234     (if available)
235 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
236     exception when getting parameters from a disconnected device
237 schoenebeck 1599
238 persson 1651 * MIDI driver:
239     - added JACK MIDI driver
240 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
241     want to (mis)use it for some purpose ("fixed" in all current MIDI
242     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
243 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
244 persson 1887 CoreMidi or AU
245 persson 1889 - fixed mingw-w64 compilation error in MME driver
246 persson 1924 - made program change handling in MIDI thread real-time safe by
247     moving the logic to a non-RT thread

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

346     instrument loading in progress (bug #113)
347 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
348     instrument with PERSISTENT load mode
349 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
350     - fixed memory leaks when issuing the following LSCP commands:
351     GET AUDIO_OUTPUT_DRIVER INFO
352     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
353     GET MIDI_INPUT_DRIVER INFO
354     GET MIDI_INPUT_DRIVER_PARAMETER INFO
355     - fixed possible compilation error when sqlite is not present
356 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
357 iliev 1847 - fixed crash when changing the audio output device of a sampler
358     channel with loaded instrument and start playing notes
359 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
360 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
361     PowerPC, which probably could cause crashes on that platform
362 persson 1889 - fixed a memory management error which could cause a crash when a
363     plugin was unloaded
364 persson 1896 - bugfix: two private structs had the same name, which could cause
365     problems if the linker chose the wrong constructor
366 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
367     Windows
368 iliev 1761
369    
370 schoenebeck 1560 Version 0.5.1 (6 December 2007)
371 schoenebeck 1454
372     * packaging changes:
373     - added autoconf checks for pthread library
374     - added autoconf check for pthread bug found on certain NPTL-enabled
375     glibc versions (see Gentoo bug report #194076)
376 senoner 1502 - added autoconf checks for MS Windows
377 schoenebeck 1454
378 persson 1455 * general changes:
379     - bugfix: the thread used by an editor plugin didn't die when the
380     editor closed
381 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
382     out all the space. operator--() did not apply size_mask after
383     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
384     order to avoid problems with the _NonVolatileReader functions.
385     - bugfix: Stream.h: added a missing divide by BytesPerSample in
386     GetWriteSpace(). Since this function is currently only used in
387     the stream's qsort() compare function, it didn't trigger any
388     bugs.
389     - Resampler.h, Synthesizer.h: cubic interpolation now works in
390     24bit mode too. Faster method to read 24bit words on little
391     endian machines (x86): replaced 3 byte reads + shifts with a 1
392     unaligned 32bit read and shift
393     - experimental support for MS Windows (MIDI input via MME, AUDIO
394     output via ASIO)
395     - made handling of SIGINT signal (Ctrl-C) a bit more robust
396 iliev 1541 - support for monitoring the total number of active disk streams
397     (new LSCP commands: GET TOTAL_STREAM_COUNT,
398     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
399 persson 1455
400 senoner 1500 * AUDIO driver:
401 persson 1534 - added Windows ASIO low latency audio driver
402 senoner 1500
403 senoner 1485 * MIDI driver:
404 schoenebeck 1495 - added MME Windows MIDI driver
405 senoner 1485
406 schoenebeck 1471 * LSCP server:
407     - added support for Windows style path / filenames, however with
408     forward slash path separators instead of backslash
409     (i.e. "C:/foo/bar.gig")
410 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
411     apostrophes as well
412 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
413     "LIST FILE INSTRUMENTS <file>" and
414     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
415     about an arbitrary instrument file on the system where the sampler is
416     running on
417 schoenebeck 1471
418 schoenebeck 1424 Version 0.5.0 (15 October 2007)
419 schoenebeck 947
420 schoenebeck 1065 * packaging changes:
421 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
422     API header files anymore
423 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
424     the Doxygen API documentation (explicitly listed in Doxyfile.in)
425 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
426     capable to execute our autoconf environment, thus no need anymore
427     to maintain the compile time configuration file (osx/version.h) for
428     OSX manually (patch by Toshi Nagata)
429 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
430     parameters
431 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
432     C++ API header files, all implementation internal global definitions
433     are now in global_private.h
434     - atomic.h is not exposed to the C++ API anymore
435     - no need to include config.h anymore for using LS's API header files
436     - fixed warnings in API doc generation
437 schoenebeck 1065
438 schoenebeck 947 * general changes:
439     - replaced the old, confusing MIDI program change mechanism by a
440     flexible MIDI instrument mapper which allows to map arbitrary
441 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
442 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
443     loaded on the respective channel when such MIDI program change
444     messages arrive, beside that, each entry allows to define a life-time
445     strategy for the instrument, so the user can define whether the
446     instrument should i.e. be permanently loaded (to be able to switch
447     quickly among sounds) or i.e. loaded just on demand when the
448     respective program change arrives (to safe RAM space), as well as a
449     global volume factor for each entry, so the user can adjust the volume
450     dynamic of his mapped instrument collection without having to modify
451 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
452     MIDI instrument maps and assign each sampler channel individually
453     a certain map, so that i.e. separation of normal instruments and
454     drumkits is possible
455 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
456     MIDI instrument maps, MIDI instruments, FX sends, global volume.
457 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
458     due to a constant size RingBuffer FIFO which is now replaced by a
459     dynamic (unlimited) size std::list FIFO
460 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
461     output channels for being processed by external effect processors
462     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
463     controllers
464 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
465 iliev 1130 - Implemented new, improved notification system
466 schoenebeck 1149 - fixed compilation errors regarding OSX
467     (patch by Toshi Nagata)
468 iliev 1161 - implemented instruments database
469 iliev 1345 - added support for escape sequences to the instruments database
470 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
471     within the sampler's process (by using instrument editor plugins),
472     you'll notice the new "Registered instrument editors:" message on
473 schoenebeck 1407 startup, added a new LSCP command:
474     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
475 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
476     given sampler channel, the plugin path can be overridden at compile
477     time with ./configure --enable-plugin-dir=/some/dir
478 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
479     in the sampler's process to safely edit instruments while playing
480     without a crash (hopefully) by either suspending single regions
481     wherever possible or if unavoidable whole engine(s)
482 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
483     policy and priority on thread level, set a minimum stack size for
484     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
485     threads simply inherited properties of starting thread instead of
486     setting their own policy and priority
487 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
488     main process did not wait for the stack trace process to finish
489     its output
490 persson 1248 - fixed some minor memory leaks
491 schoenebeck 1259 - reenabled assembly features support, at the moment only for
492     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
493 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
494     register, to avoid relocations in the text segment at runtime)
495 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
496 schoenebeck 947
497     * MIDI driver:
498     - dispatch bank select (MSB and LSB) messages
499    
500 schoenebeck 1049 * audio driver:
501     - the ALSA audio output driver parameters now reflect the correct
502     parameter value ranges for the respective selected sound card
503     (patch by Till Wimmer, a bit fixed and extended)
504    
505 persson 951 * Gigasampler format engine:
506     - if a filter is used and EG2 finishes before EG1, let the voice
507     die when EG2 has finished (this fixes a problem with clicks and
508     voice starvation for some gigs)
509 persson 1038 - playback is no longer disabled during instrument loading
510     - all notes playing on a channel that changes its instrument keep
511     playing with the old instrument until they get a note off
512     command
513 persson 1039 - EG fix: a release value of zero could cause noises or crash
514 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
515 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
516     above max sustain level, which means that there is a decay phase
517     even if sustain is 100%
518 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
519     noises or crashes
520 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
521 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
522     supplied to the configure script (fixes #46)
523 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
524     instead of a fix value
525 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
526     127 (solo mode) only kill voices if the respective mode really
527     changed
528 persson 951
529 schoenebeck 1244 * LSCP server:
530     - fixed compile time error for old Bison versions
531     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
532 schoenebeck 1245 - parser now supports extended ASCII character set
533     (up to ASCII code 255, i.e. includes now umlauts and accents)
534     - filename arguments in LSCP commands now allow to use escape
535     sequences, that is directly literal as one of: \', \", \\, \n, \r,
536     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
537     code value like \xf2) (fixes bug #24)
538 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
539     least one of their text-based parameters (i.e. name, description):
540     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
541     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
542     "SET DB_INSTRUMENT_DIRECTORY NAME",
543     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
544     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
545     "FIND DB_INSTRUMENT_DIRECTORIES"
546 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
547     occured, the unexpected character and the actually expected, possible
548     character(s), the latter only if less than 5 possibilities)
549 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
550     settings
551 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
552     of strings were treated as being one string containing commas
553     (fixes #57)
554 schoenebeck 1244
555 iliev 959 * Bug fixes:
556     - fixed crash occurring on certain LSCP scripts (Bug 39)
557 persson 1038 - another thread safety fix for lscp "load engine" and "set
558     channel audio output device"
559 iliev 1283 - fixed a crash which occurs when reassigning the same engine
560     on a sampler channel with connected MIDI device
561 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
562     device connected to a sampler channel to number less then or equal
563     to the index of the port to which the sampler channel is connected.
564 iliev 1296 - The previous bindings were not been disconnected when altering
565     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
566     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
567 iliev 1297 - The active stream/voice count statistic was incorrect.
568 iliev 1298 - notification events were not been sent for some sampler
569     channel changes
570 iliev 1305 - added default min and max values to restrict the number of allowed
571     audio output channels and MIDI input ports
572 iliev 1306 - the connection to the PCM interface is now closed when destroying
573     an audio output device
574 schoenebeck 1332 - files with slash in their path or filename could not be loaded
575 iliev 959
576 schoenebeck 1221 * test cases:
577     - updated and fixed (haven't been touched in a while)
578    
579 schoenebeck 937 Version 0.4.0 (24 November 2006)
580 persson 696
581 schoenebeck 697 * packaging changes:
582 capela 868 - changed deprecated copyright attribute to license; added ldconfig
583     to post-(un)install steps; added devel package for liblinuxsampler;
584     to linuxsampler.spec (RPM)
585 schoenebeck 697 - install necessary development header files for allowing 3rd party
586     applications to link against liblinuxsampler
587     - liblinuxsampler's API documentation can be generated with 'make docs'
588     (Doxygen required)
589 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
590     implementation (currently either an integer math solution or a
591     di-harmonic approximation), automatic detection can be overriden
592     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
593     configure script argument though (mandatory for cross-compilation)
594 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
595     provided some on his own (as CXXFLAGS)
596 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
597     messages
598 schoenebeck 852 - added compile time options to allow disabling the various audio and
599     MIDI drivers
600 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
601     (patch by Ebrahim Mayat)
602 schoenebeck 697
603 persson 696 * Gigasampler format engine:
604 schoenebeck 738 - extensive synthesis optimization
605     (reimplementation of EGs and LFO(s), removed synthesis parameter
606     prerendering and the synthesis parameter matrix in general, splitting
607     each audio fragment into subfragments now where each subfragment uses
608 persson 830 constant pitch and filter coefficients. The volume coefficient is
609     linearly interpolated inside a subfragment, unless
610     --disable-interpolate-volume is set.)
611 persson 696 - fine tuning of the EG modulation parameters
612 persson 729 - improved filter cutoff calculation by adding support for the
613     following gig parameters: Cutoff freq (used when no cutoff
614     controller is defined), Control invert, Minimum cutoff, Velocity
615 persson 791 curve and Velocity range. The keyboard tracking now scales
616     cutoff frequency instead of resonance.
617 persson 877 - added support for gig parameter Resonance.
618 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
619 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
620     which can be overridden with --enable-global-attenuation
621 persson 783 - EG fixes: made the length of "attack hold" stage more
622     accurate. Release stage can now start before attack stage
623 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
624     time now has a minimal value to prevent clicks.
625 persson 799 - fixed pitch changes larger than one octave
626 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
627     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
628     all modes can be altered via standard GM messages, that is CC5 for
629     altering portamento time, CC65 for enabling / disabling portamento
630     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
631 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
632     parameter) and crossfade
633 persson 831 - added support for the "attenuation controller threshold" gig
634     parameter
635 persson 832 - added smoothing of volume changes caused by control change
636     messages
637 persson 865 - sample loop parameters are now taken from the DimensionRegion
638     instead of the wave chunk
639     - fixed keyswitching for v3 gigs with a number of keyswitch splits
640     not equal to a power of two
641 persson 877 - reimplementation of the filter algorithm. The new filter is more
642     accurate and supports all gig filter types, including bandreject
643     and lowpass turbo.
644 persson 903 - real support for 24 bit samples - samples are not truncated to
645     16 bits anymore
646     - support for aftertouch (channel pressure, not polyphonic
647     aftertouch)
648 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
649     amplifying from 0)
650 persson 696
651 schoenebeck 711 * LSCP server:
652     - fixed application exit on broken pipe error (fixes bug #20)
653 iliev 793 - fixed the notification messages delay due to lack of
654     network activity (fixes bug #26)
655 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
656     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
657 schoenebeck 711
658 schoenebeck 838 * audio driver:
659     - added aRts audio output driver (by no means RT safe)
660    
661 schoenebeck 775 * MIDI driver:
662     - fixed legacy sysex code which caused dispatching of MIDI SysEx
663     messages several times instead of once
664 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
665     for events (i.e. for offline rendering based MIDI drivers)
666 persson 922 - added checks for bad MIDI data
667 schoenebeck 775
668 schoenebeck 900 * linuxsampler application:
669     - show available sampler engine types on startup
670    
671 schoenebeck 705 * general changes:
672     - support for muting sampler channels and solo mode of the same, two new
673     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
674     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
675     introduced for this, the behavior is the same like on a mixer console
676 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
677     --enable-process-muted-channels which can be used to enable the
678     processing of muted channels.
679 iliev 777 - support for sostenuto pedal
680 iliev 779 - support for monitoring the total number of active voices
681 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
682     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
683 persson 835 - fixed some memory management errors
684 persson 841 - fixed some concurrency problems that could lead to crashes when
685     LSCP commands were executed
686 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
687     sampler channel (fixes bug #36)
688 schoenebeck 705
689 schoenebeck 692 Version 0.3.3 (15 July 2005)
690 schoenebeck 686
691     * packaging changes:
692     - fixed compilation with gcc 4.0
693    
694 schoenebeck 687 * Gigasampler format engine:
695     - LFO preprocessing was performed even though the respective LFO was
696     disabled by the instrument patch (minor efficiency fix)
697 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
698     for volume ramp downs in the same fragment (needed for current voice
699     stealing implementation) then simply inform the user with a warning
700     about possible click sounds and reduce the volume ramp down
701     appropriately instead of cancelling the audio device connection
702 schoenebeck 687
703 schoenebeck 677 Version 0.3.2 (24 June 2005)
704 schoenebeck 609
705     * packaging changes:
706     - updated autotools build files to compile on OS X
707     (conditional compilation of CoreMIDI and MidiShare drivers)
708 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
709     './configure --disable-asm' (definitely not recommended)
710 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
711     - require automake (>= 1.5) for 'make -f Makefile.cvs'
712     (due to 'dist-bzip2' automake option)
713 schoenebeck 649
714     * Gigasampler format engine:
715     - support for the gig parameters for "release velocity response" curves
716     - fine tuning of the EGADSR envelope
717     - volume of release triggered samples now depends on note-on velocity,
718     note length and gig parameter "release trigger decay" instead of
719     note-off velocity.
720 schoenebeck 663 - revised voice stealing
721     (fixes crash and endless loop caused by voice stealing)
722 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
723 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
724     instead of when the respective voice is actually launched
725     (fixes undefined behavior if stolen voices belonged to a key group -
726     this case was followed by a "killed voice survived" error message)
727 schoenebeck 669 - fixed minor issue with null/silence samples
728     (those stole voices even though they don't need a voice at all which
729     resulted in "voice stealing didn't work out" messages)
730 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
731     instrument or audio output device change
732 schoenebeck 654
733 schoenebeck 620 * LSCP server:
734 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
735 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
736 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
737 schoenebeck 609
738 schoenebeck 668 * linuxsampler application:
739     - added command line parameters --lscp-addr and --lscp-port to override
740     default IP address and port of LSCP server
741    
742 schoenebeck 579 Version 0.3.1 (24 May 2005)
743    
744     * initial release
