File size: 37217 byte(s)
* revised previously added new LSCP commands regarding effect handling:
  renamed "master effects" to "send effects", since this is the actual
  correct common term for those effects
* also corrected the names regarding "send effects" in the respective
  methods of the "FxSsnd" class and "AudioOutputDevice" class of the
  sampler's C++ API, the old methods are still available but marked as
  deprecated and scheduled for removal
* added LSCP command "SET FX_SEND SEND_EFFECT <sampler_channel>
  <fx_send_id> <effect_chain> <chain_pos>"
* added LSCP command "REMOVE FX_SEND SEND_EFFECT <sampler_channel>
  <fx_send_id>"
* added a list of common known LADSPA paths (for Windows and POSIX) which
  will be automatically checked for being used as LADSPA plugin directory
  (if the user did not set the LADSPA_PATH environment variable explicitly)
* bumped version to 1.0.0.cvs8

1 schoenebeck 1993 Version CVS HEAD (?)
2    
3 persson 2086 * packaging changes:
4     - fixed building with newer MinGW-w64
5    
6     * general changes:
7 iliev 2012 - Refactoring: moved the independent code from
8     the Gigasampler format engine to base classes
9 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
10     respective profiling code is currently broken
11 schoenebeck 2053 - Introduced support for optional environment variable
12     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
13     where the sampler shall look for instrument editor plugins
14     (patch by Luis Garrido, slightly modified).
15 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
16     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
17     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
18     note (in this implementation of the sampler its simply hard routed to
19     the 1st effect send of the sampler channel, no matter what the actual
20     effect type is)
21     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
22     note (in this implementation of the sampler its simply hard routed to
23     the 2nd effect send of the sampler channel, no matter what the actual
24     effect type is)
25 schoenebeck 2124 - implemented support for internal LADSPA effects
26 iliev 2012
27 persson 2043 * Gigasampler format engine:
28     - implemented the "round robin keyboard" dimension

128 schoenebeck 1599
129 schoenebeck 1639 * packaging changes:
130     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

148 schoenebeck 1639
149 schoenebeck 1601 * general changes:
150     - bugfix: on some POSIX systems instrument editor plugins refused to
151     load as we used a non-portable Linux specific struct field
152     (fixes bug #70, patch by Ronald Baljeu)
153 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
154     plugin DLL on Windows systems failed

157     unnecessarily long after an update
158 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
159     events (e.g. to highlight the pressed keys on the virtual keyboard
160     of gigedit)
161 schoenebeck 1659 - added support for triggering notes by instrument editors (see above)
162 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
163 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation

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

175 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
176     be switched on by command line option "--stacktrace" (the automatic
177     stacktrace mechanism seems to be broken on most systems at the moment)
178 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
179     a pointer to the launched InstrumentEditor object
180 schoenebeck 1876 - added optional 3rd party user data parameter for following
181     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
182     InstrumentEditor::Launch(),

190 schoenebeck 1601
191 schoenebeck 1599 * audio driver:
192     - removed the nonsense audio channel constraint (which was hard coded to
193     max. 100 audio channels) for most audio drivers
194 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
195     opposed to the LSCP specs
196 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
197     reflected the wrong value

201 persson 1748 jack_client_new
202 iliev 1829 - added (experimental) CoreAudio driver
203 persson 1888 - applied old fixes to the ASIO driver that were included in the
204     previous binary release but accidentally never committed to CVS
205     (fixes #117)
206 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
207     win64)
208 persson 1895 - VST: added support for sample rate and buffer size changes
209     - VST: close editor (Fantasia) when the VST is removed

218     AudioChannel::CopyTo() methods using GCC vector exensions
219     (if available)
220 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
221     exception when getting parameters from a disconnected device
222 schoenebeck 1599
223 persson 1651 * MIDI driver:
224     - added JACK MIDI driver
225 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
226     want to (mis)use it for some purpose ("fixed" in all current MIDI
227     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
228 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
229 persson 1887 CoreMidi or AU
230 persson 1889 - fixed mingw-w64 compilation error in MME driver
231 persson 1924 - made program change handling in MIDI thread real-time safe by
232     moving the logic to a non-RT thread
233 persson 1951 - fixed minor memory leak in ALSA driver
234 persson 1651
235 schoenebeck 1604 * instruments database:

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

337     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
338     GET MIDI_INPUT_DRIVER INFO
339     GET MIDI_INPUT_DRIVER_PARAMETER INFO
340     - fixed possible compilation error when sqlite is not present
341 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
342 iliev 1847 - fixed crash when changing the audio output device of a sampler
343     channel with loaded instrument and start playing notes
344 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
345 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
346     PowerPC, which probably could cause crashes on that platform
347 persson 1889 - fixed a memory management error which could cause a crash when a
348     plugin was unloaded

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