* sfz engine: added support for trigger=release and rt_decay

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

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

77 schoenebeck 1639
78 schoenebeck 1601 * general changes:

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

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

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

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

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