  Fine-tuned the default velocity curve.

1 schoenebeck 1993 Version CVS HEAD (?)
2    
3 iliev 2012 * General changes:
4     - Refactoring: moved the independent code from
5     the Gigasampler format engine to base classes
6 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
7     respective profiling code is currently broken
8 schoenebeck 2053 - Introduced support for optional environment variable
9     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
10     where the sampler shall look for instrument editor plugins
11     (patch by Luis Garrido, slightly modified).
12 iliev 2012
13 persson 2043 * Gigasampler format engine:
14     - implemented the "round robin keyboard" dimension
15     - fixed round robin and random dimensions for cases when number of
16     dimension zones is not a power of two
17     - made round robin use a counter for each region instead of each
18     key
19    
20 schoenebeck 2047 * SFZ format engine:
21 iliev 2012 - Initial implementation (not usable yet)
22 persson 2055 - added support for v2 multiple stage envelope generators
23     - added a fine-tuned v1 envelope generator instead of using the
24     one from the gig engine
25 persson 2058 - fixed memory leak and memory handling errors
26 persson 2061 - added support for trigger=first, trigger=legato and sw_previous
27 persson 2058 - allow non-numerical key values ("C#4" for example)
28     - "key" opcode now sets pitch_keycenter too
29     - fixed error when unloading instrument with same sample used by
30     multiple regions
31     - added some opcode aliases, like loopmode for loop_mode, to be
32     more compatible

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

62 schoenebeck 1599
63 schoenebeck 1639 * packaging changes:
64     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
65     causing e.g. the libgig test to fail when

77     directory above)
78 persson 1899 - configure script fix: removed unconditional use of SSE
79 persson 1923 - fixed building with sqlite installed in a non-standard directory
80 persson 1931 - when cross-compiling, don't try to create instruments.db
81     - fix for new mingw-w64 version, which has usleep
82 schoenebeck 1639
83 schoenebeck 1601 * general changes:

86     (fixes bug #70, patch by Ronald Baljeu)
87 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
88     plugin DLL on Windows systems failed
89 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded
90     - optimized the SynchronizedConfig class so it doesn't wait
91     unnecessarily long after an update
92 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
93     events (e.g. to highlight the pressed keys on the virtual keyboard
94     of gigedit)
95 schoenebeck 1659 - added support for triggering notes by instrument editors (see above)
96 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
97 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation

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

125 schoenebeck 1599 * audio driver:
126     - removed the nonsense audio channel constraint (which was hard coded to
127     max. 100 audio channels) for most audio drivers
128 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
129     opposed to the LSCP specs
130 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
131     reflected the wrong value
132 persson 1644 - fixed a memory management bug in ASIO driver
133 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used

135 persson 1748 jack_client_new
136 iliev 1829 - added (experimental) CoreAudio driver
137 persson 1888 - applied old fixes to the ASIO driver that were included in the
138     previous binary release but accidentally never committed to CVS
139     (fixes #117)
140 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
141     win64)
142 persson 1895 - VST: added support for sample rate and buffer size changes
143     - VST: close editor (Fantasia) when the VST is removed

152     AudioChannel::CopyTo() methods using GCC vector exensions
153     (if available)
154 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
155     exception when getting parameters from a disconnected device
156 schoenebeck 1599
157 persson 1651 * MIDI driver:
158     - added JACK MIDI driver
159 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
160     want to (mis)use it for some purpose ("fixed" in all current MIDI
161     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
162 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
163 persson 1887 CoreMidi or AU
164 persson 1889 - fixed mingw-w64 compilation error in MME driver
165 persson 1924 - made program change handling in MIDI thread real-time safe by
166     moving the logic to a non-RT thread
167 persson 1951 - fixed minor memory leak in ALSA driver
168 persson 1651
169 schoenebeck 1604 * instruments database:
170 iliev 1603 - avoid time consuming samples scanning when adding instruments
171     to the instruments database
172 iliev 1727 - added support for handling lost files in the instruments database

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