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 iliev 2012
16 persson 2043 * Gigasampler format engine:
17     - implemented the "round robin keyboard" dimension
18     - fixed round robin and random dimensions for cases when number of
19     dimension zones is not a power of two
20     - made round robin use a counter for each region instead of each
21     key
22    
23 schoenebeck 2047 * SFZ format engine:
24 iliev 2012 - Initial implementation (not usable yet)
25 persson 2055 - added support for v2 multiple stage envelope generators

29 persson 2061 - added support for trigger=first, trigger=legato and sw_previous
30 persson 2058 - allow non-numerical key values ("C#4" for example)
31     - "key" opcode now sets pitch_keycenter too
32     - fixed error when unloading instrument with same sample used by
33     multiple regions
34     - added some opcode aliases, like loopmode for loop_mode, to be
35     more compatible

48 iliev 2012 - Initial implementation (not usable yet)
49    
50     * Host plugins:

52 iliev 1994 - Listen to all interfaces on Mac OS X (INADDR_ANY)
53 persson 2045 - VST bugfix: If the host called resume() before and after
54     changing sample rate or block size, the number of channels was
55     incorrectly set to two. This caused silence in Cubase 5.
56 schoenebeck 1993
57     * MIDI driver:

69 schoenebeck 1599
70 schoenebeck 1639 * packaging changes:
71     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

95     plugin DLL on Windows systems failed
96 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded

98     unnecessarily long after an update
99 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
100     events (e.g. to highlight the pressed keys on the virtual keyboard
101     of gigedit)
102 schoenebeck 1659 - added support for triggering notes by instrument editors (see above)
103 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
104 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation

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

132 schoenebeck 1599 * audio driver:
133     - removed the nonsense audio channel constraint (which was hard coded to
134     max. 100 audio channels) for most audio drivers
135 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
136     opposed to the LSCP specs
137 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
138     reflected the wrong value
139 persson 1644 - fixed a memory management bug in ASIO driver
140 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used
141 persson 1777 - JACK: use jack_client_open instead of the deprecated
142 persson 1748 jack_client_new
143 iliev 1829 - added (experimental) CoreAudio driver
144 persson 1888 - applied old fixes to the ASIO driver that were included in the
145     previous binary release but accidentally never committed to CVS
146     (fixes #117)
147 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
148     win64)
149 persson 1895 - VST: added support for sample rate and buffer size changes
150     - VST: close editor (Fantasia) when the VST is removed

158 schoenebeck 1930 - performance optimization of AudioChannel::MixTo() and
159     AudioChannel::CopyTo() methods using GCC vector exensions
160     (if available)
161 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
162     exception when getting parameters from a disconnected device
163 schoenebeck 1599
164 persson 1651 * MIDI driver:
165     - added JACK MIDI driver
166 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
167     want to (mis)use it for some purpose ("fixed" in all current MIDI
168     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
169 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
170 persson 1887 CoreMidi or AU
171 persson 1889 - fixed mingw-w64 compilation error in MME driver
172 persson 1924 - made program change handling in MIDI thread real-time safe by
173     moving the logic to a non-RT thread

175 persson 1651
176 schoenebeck 1604 * instruments database:
177 iliev 1603 - avoid time consuming samples scanning when adding instruments
178     to the instruments database
179 iliev 1727 - added support for handling lost files in the instruments database

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