* sfz engine: added support for off_mode=normal

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
33 persson 2061 - added support for trigger=release and rt_decay
34 persson 2063 - added support for off_mode=normal
35 iliev 2012
36 schoenebeck 2047 * SoundFont format engine:
37 iliev 2012 - Initial implementation (not usable yet)
38    
39     * Host plugins:
40 schoenebeck 1993 - AU bugfix: failed to destroy its audio/MIDI devices
41 iliev 1994 - Listen to all interfaces on Mac OS X (INADDR_ANY)
42 persson 2045 - VST bugfix: If the host called resume() before and after
43     changing sample rate or block size, the number of channels was
44     incorrectly set to two. This caused silence in Cubase 5.
45 schoenebeck 1993
46     * MIDI driver:
47     - ALSA MIDI driver supports now "NAME" device parameter, for overriding
48     the ALSA sequencer client name

58 schoenebeck 1599
59 schoenebeck 1639 * packaging changes:
60     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
61     causing e.g. the libgig test to fail when
62     "./configure --disable-jack-driver" was used
63     (patch by Alexis Ballier)

77     - fix for new mingw-w64 version, which has usleep
78 schoenebeck 1639
79 schoenebeck 1601 * general changes:

81     load as we used a non-portable Linux specific struct field
82     (fixes bug #70, patch by Ronald Baljeu)
83 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
84     plugin DLL on Windows systems failed
85 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded
86     - optimized the SynchronizedConfig class so it doesn't wait
87     unnecessarily long after an update
88 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
89     events (e.g. to highlight the pressed keys on the virtual keyboard
90     of gigedit)
91 schoenebeck 1659 - added support for triggering notes by instrument editors (see above)
92 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
93 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation
94     is only used by very few systems, most pick the int math
95     implementation, which is usually faster)

104 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
105 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
106     be switched on by command line option "--stacktrace" (the automatic
107     stacktrace mechanism seems to be broken on most systems at the moment)
108 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
109     a pointer to the launched InstrumentEditor object
110 schoenebeck 1876 - added optional 3rd party user data parameter for following
111     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
112     InstrumentEditor::Launch(),
113     InstrumentManager::LaunchInstrumentEditor()
114 persson 1887 - theoretical fix: made SynchronizedConfig follow C++0x memory

120 schoenebeck 1601
121 schoenebeck 1599 * audio driver:
122     - removed the nonsense audio channel constraint (which was hard coded to
123     max. 100 audio channels) for most audio drivers
124 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
125     opposed to the LSCP specs
126 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
127     reflected the wrong value
128 persson 1644 - fixed a memory management bug in ASIO driver
129 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used
130 persson 1777 - JACK: use jack_client_open instead of the deprecated
131 persson 1748 jack_client_new
132 iliev 1829 - added (experimental) CoreAudio driver
133 persson 1888 - applied old fixes to the ASIO driver that were included in the
134     previous binary release but accidentally never committed to CVS
135     (fixes #117)
136 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
137     win64)
138 persson 1895 - VST: added support for sample rate and buffer size changes
139     - VST: close editor (Fantasia) when the VST is removed
140 persson 1908 - VST: avoid opening Fantasia more than once for each VST instance

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

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