* sfz engine: added support for v2 multiple stage envelope generators
* sfz engine: added a fine-tuned v1 envelope generator instead of
  using the one from the gig engine

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 iliev 2012
26 schoenebeck 2047 * SoundFont format engine:
27 iliev 2012 - Initial implementation (not usable yet)
28    
29     * Host plugins:
30 schoenebeck 1993 - AU bugfix: failed to destroy its audio/MIDI devices
31 iliev 1994 - Listen to all interfaces on Mac OS X (INADDR_ANY)
32 persson 2045 - VST bugfix: If the host called resume() before and after
33     changing sample rate or block size, the number of channels was
34     incorrectly set to two. This caused silence in Cubase 5.
35 schoenebeck 1993
36     * MIDI driver:
37     - ALSA MIDI driver supports now "NAME" device parameter, for overriding
38     the ALSA sequencer client name
39    
40 schoenebeck 2024 * LSCP server:
41     - added support for sending MIDI CC messages via LSCP command
42     "SEND CHANNEL MIDI_DATA CC <sampler-chan> <ctrl> <val>"

48 schoenebeck 1599
49 schoenebeck 1639 * packaging changes:
50     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
51     causing e.g. the libgig test to fail when
52     "./configure --disable-jack-driver" was used
53     (patch by Alexis Ballier)

61 persson 1897 - Windows: look for editor plugins and Fantasia using base
62 schoenebeck 1928 directory of liblinuxsampler dll (look in the same directory and one
63     directory above)
64 persson 1899 - configure script fix: removed unconditional use of SSE
65 persson 1923 - fixed building with sqlite installed in a non-standard directory
66 persson 1931 - when cross-compiling, don't try to create instruments.db
67     - fix for new mingw-w64 version, which has usleep
68 schoenebeck 1639
69 schoenebeck 1601 * general changes:
70     - bugfix: on some POSIX systems instrument editor plugins refused to
71     load as we used a non-portable Linux specific struct field
72     (fixes bug #70, patch by Ronald Baljeu)
73 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
74     plugin DLL on Windows systems failed
75 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded
76     - optimized the SynchronizedConfig class so it doesn't wait
77     unnecessarily long after an update
78 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
79     events (e.g. to highlight the pressed keys on the virtual keyboard
80     of gigedit)
81 schoenebeck 1659 - added support for triggering notes by instrument editors (see above)
82 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
83 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation
84     is only used by very few systems, most pick the int math
85     implementation, which is usually faster)
86 persson 1748 - fixes for audio drivers with varying buffer sizes
87 persson 1777 - experimental support for running LinuxSampler as a DSSI, LV2 and
88     VST plugin
89 iliev 1789 - notification events for stream/voice count statistics are now sent

94 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
95 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
96     be switched on by command line option "--stacktrace" (the automatic
97     stacktrace mechanism seems to be broken on most systems at the moment)
98 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
99     a pointer to the launched InstrumentEditor object
100 schoenebeck 1876 - added optional 3rd party user data parameter for following
101     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
102     InstrumentEditor::Launch(),
103     InstrumentManager::LaunchInstrumentEditor()
104 persson 1887 - theoretical fix: made SynchronizedConfig follow C++0x memory
105     model more strictly
106 persson 1895 - fixes for using large audio device buffers
107 persson 1951 - Windows: add the installation directory to the DLL search path
108     when loading an editor plugin (solves problems with VST and
109     gigedit on systems with other GTK versions installed)
110 schoenebeck 1601
111 schoenebeck 1599 * audio driver:
112     - removed the nonsense audio channel constraint (which was hard coded to
113     max. 100 audio channels) for most audio drivers
114 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
115     opposed to the LSCP specs
116 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
117     reflected the wrong value
118 persson 1644 - fixed a memory management bug in ASIO driver
119 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used
120 persson 1777 - JACK: use jack_client_open instead of the deprecated
121 persson 1748 jack_client_new
122 iliev 1829 - added (experimental) CoreAudio driver
123 persson 1888 - applied old fixes to the ASIO driver that were included in the
124     previous binary release but accidentally never committed to CVS
125     (fixes #117)
126 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
127     win64)
128 persson 1895 - VST: added support for sample rate and buffer size changes
129     - VST: close editor (Fantasia) when the VST is removed
130 persson 1908 - VST: avoid opening Fantasia more than once for each VST instance
131     - VST: export main function as "main" on Linux too (fix for
132     energyXT)

134     stereo
135 persson 1922 - added channel routing, fxsends and midi maps to the settings
136     stored in the plugin state
137 schoenebeck 1930 - performance optimization of AudioChannel::MixTo() and
138     AudioChannel::CopyTo() methods using GCC vector exensions
139     (if available)
140 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
141     exception when getting parameters from a disconnected device
142 schoenebeck 1599
143 persson 1651 * MIDI driver:
144     - added JACK MIDI driver
145 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
146     want to (mis)use it for some purpose ("fixed" in all current MIDI
147     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
148 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
149 persson 1887 CoreMidi or AU
150 persson 1889 - fixed mingw-w64 compilation error in MME driver
151 persson 1924 - made program change handling in MIDI thread real-time safe by
152     moving the logic to a non-RT thread
153 persson 1951 - fixed minor memory leak in ALSA driver
154 persson 1651
155 schoenebeck 1604 * instruments database:
156 iliev 1603 - avoid time consuming samples scanning when adding instruments
157     to the instruments database
158 iliev 1727 - added support for handling lost files in the instruments database
159 iliev 1781 - Implemented option for adding instruments in separate directories
160     in the instruments database
161     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
162 persson 1908 - work-around for missing fnmatch function on Windows to make
163     instrument database compilable
164 schoenebeck 1930 - added instrument database support on Windows
165     works with both standalone mode and VST plugin.
166     the instruments DB file is located in
167     %USERPROFILE%\.linuxsampler\instruments.db which allows different
168     databases for each windows user
169     if no DB is present it automatically creates the .linuxsampler subdir
170     and then creates an empty DB
171 persson 1943 - fixed recursive import, which was broken on Windows
172 iliev 1603
173 persson 1644 * Gigasampler format engine:
174     - fixed a memory leak that could happen when a channel was deleted
175     while notes were playing
176 persson 1646 - made it possible to load an instrument even if the audio thread
177     isn't running
178 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
179     enough for piano gigs with pedal noise samples
180 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
181     respective FX send MIDI controller was used
182 schoenebeck 1724 - added support for GM global device volume SysEx message
183 schoenebeck 1762 (can be selected at compile time to either apply globally to the
184     whole sampler [default] or only to the sampler channels that are
185     connected to the respective MIDI input port the SysEx message arrived
186     on)
187 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
188     sometimes wrongly killed in the same buffer, causing no sound to
189     be played
190 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
191     which is usally used to switch a part between chromatic sounds and
192     drumkit sounds (as opposed to their common default setting of MIDI
193     part 10 being a drumkit part and all other ones chromatic parts), in
194     LS however one can switch between the first 16 MIDI instrument maps
195     defined for the sampler
196 persson 1764 - made it possible to create multiple sample channels even if the
197     audio thread isn't running
198 persson 1844 - fixed crash when removing channel with active voices (#116)
199 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
200     un-cache the respective sample if it's really not used by any
201     sampler engine anymore
202     - re-cache samples in case they were changed by an instrument editor,
203     e.g. when a sample was added while playing (#82)
204 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
205     same time stamp as the voice's note-on event and occured both in the
206     same audio fragment cycle (fixes bug #112)
207 persson 1858 - added support for the "fine tune" and "pitch bend range"
208     instrument-level gig parameters
209     - fixed minor artifacts in pitch bend handling
210 schoenebeck 1860 - added support for GS Reset SysEx message
211 persson 1862 - allow gig files to use unlimited downward pitch shifting
212     - added a limit check for upward pitch shifting
213 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
214     note was silent
215 persson 1923 - fixed crash happening when a pitch bend event arrived at the
216     same time a new instrument was loading
217 persson 1644
218 schoenebeck 1687 * LSCP server:
219     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
220     react on MIDI data arriving on certain sampler channels (so far only
221     Note-On and Note-Off events are sent via this LSCP event)
222 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
223     react on MIDI data arriving on certain MIDI input devices (so far only
224     Note-On and Note-Off events are sent via this LSCP event)
225 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
226     SET DB_INSTRUMENT FILE_PATH
227 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
228     frontends to send MIDI messages to specific sampler channel
229     - added two additional fields to GET FILE INSTRUMENT INFO command -
230     KEY_BINDINGS and KEYSWITCH_BINDINGS
231 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
232     was incorrect
233 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
234 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
235     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
236     be triggered respectively
237     - added new LSCP command "SET STREAMS" to globally alter the maximum
238     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
239     which will be triggered respectively
240 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
241     a gigedit file dialog is opened)
242 iliev 1848 - close all connections when LSCPServer is deleted
243 iliev 1882 - hard close of all sockets on exit
244 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
245     driver
246 schoenebeck 1687
247 iliev 1761 * Bug fixes:
248     - fixed a crash which occurs when removing a sampler channel waiting
249     to start instrument loading after another channel
250 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
251     instrument loading in progress (bug #113)
252 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
253     instrument with PERSISTENT load mode
254 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
255     - fixed memory leaks when issuing the following LSCP commands:
256     GET AUDIO_OUTPUT_DRIVER INFO
257     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
258     GET MIDI_INPUT_DRIVER INFO
259     GET MIDI_INPUT_DRIVER_PARAMETER INFO
260     - fixed possible compilation error when sqlite is not present
261 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
262 iliev 1847 - fixed crash when changing the audio output device of a sampler
263     channel with loaded instrument and start playing notes
264 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
265 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
266     PowerPC, which probably could cause crashes on that platform
267 persson 1889 - fixed a memory management error which could cause a crash when a
268     plugin was unloaded
269 persson 1896 - bugfix: two private structs had the same name, which could cause
270     problems if the linker chose the wrong constructor
271 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
272     Windows
273 iliev 1761
274    
275 schoenebeck 1560 Version 0.5.1 (6 December 2007)
276 schoenebeck 1454
277     * packaging changes:
278     - added autoconf checks for pthread library
279     - added autoconf check for pthread bug found on certain NPTL-enabled
280     glibc versions (see Gentoo bug report #194076)
281 senoner 1502 - added autoconf checks for MS Windows
282 schoenebeck 1454
283 persson 1455 * general changes:
284     - bugfix: the thread used by an editor plugin didn't die when the
285     editor closed
286 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
287     out all the space. operator--() did not apply size_mask after
288     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
289     order to avoid problems with the _NonVolatileReader functions.
290     - bugfix: Stream.h: added a missing divide by BytesPerSample in
291     GetWriteSpace(). Since this function is currently only used in
292     the stream's qsort() compare function, it didn't trigger any
293     bugs.
294     - Resampler.h, Synthesizer.h: cubic interpolation now works in
295     24bit mode too. Faster method to read 24bit words on little
296     endian machines (x86): replaced 3 byte reads + shifts with a 1
297     unaligned 32bit read and shift
298     - experimental support for MS Windows (MIDI input via MME, AUDIO
299     output via ASIO)
300     - made handling of SIGINT signal (Ctrl-C) a bit more robust
301 iliev 1541 - support for monitoring the total number of active disk streams
302     (new LSCP commands: GET TOTAL_STREAM_COUNT,
303     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
304 persson 1455
305 senoner 1500 * AUDIO driver:
306 persson 1534 - added Windows ASIO low latency audio driver
307 senoner 1500
308 senoner 1485 * MIDI driver:
309 schoenebeck 1495 - added MME Windows MIDI driver
310 senoner 1485
311 schoenebeck 1471 * LSCP server:
312     - added support for Windows style path / filenames, however with
313     forward slash path separators instead of backslash
314     (i.e. "C:/foo/bar.gig")
315 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
316     apostrophes as well
317 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
318     "LIST FILE INSTRUMENTS <file>" and
319     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
320     about an arbitrary instrument file on the system where the sampler is
321     running on
322 schoenebeck 1471
323 schoenebeck 1424 Version 0.5.0 (15 October 2007)
324 schoenebeck 947
325 schoenebeck 1065 * packaging changes:
326 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
327     API header files anymore
328 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
329     the Doxygen API documentation (explicitly listed in Doxyfile.in)
330 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
331     capable to execute our autoconf environment, thus no need anymore
332     to maintain the compile time configuration file (osx/version.h) for
333     OSX manually (patch by Toshi Nagata)
334 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
335     parameters
336 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
337     C++ API header files, all implementation internal global definitions
338     are now in global_private.h
339     - atomic.h is not exposed to the C++ API anymore
340     - no need to include config.h anymore for using LS's API header files
341     - fixed warnings in API doc generation
342 schoenebeck 1065
343 schoenebeck 947 * general changes:
344     - replaced the old, confusing MIDI program change mechanism by a
345     flexible MIDI instrument mapper which allows to map arbitrary
346 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
347 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
348     loaded on the respective channel when such MIDI program change
349     messages arrive, beside that, each entry allows to define a life-time
350     strategy for the instrument, so the user can define whether the
351     instrument should i.e. be permanently loaded (to be able to switch
352     quickly among sounds) or i.e. loaded just on demand when the
353     respective program change arrives (to safe RAM space), as well as a
354     global volume factor for each entry, so the user can adjust the volume
355     dynamic of his mapped instrument collection without having to modify
356 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
357     MIDI instrument maps and assign each sampler channel individually
358     a certain map, so that i.e. separation of normal instruments and
359     drumkits is possible
360 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
361     MIDI instrument maps, MIDI instruments, FX sends, global volume.
362 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
363     due to a constant size RingBuffer FIFO which is now replaced by a
364     dynamic (unlimited) size std::list FIFO
365 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
366     output channels for being processed by external effect processors
367     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
368     controllers
369 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
370 iliev 1130 - Implemented new, improved notification system
371 schoenebeck 1149 - fixed compilation errors regarding OSX
372     (patch by Toshi Nagata)
373 iliev 1161 - implemented instruments database
374 iliev 1345 - added support for escape sequences to the instruments database
375 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
376     within the sampler's process (by using instrument editor plugins),
377     you'll notice the new "Registered instrument editors:" message on
378 schoenebeck 1407 startup, added a new LSCP command:
379     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
380 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
381     given sampler channel, the plugin path can be overridden at compile
382     time with ./configure --enable-plugin-dir=/some/dir
383 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
384     in the sampler's process to safely edit instruments while playing
385     without a crash (hopefully) by either suspending single regions
386     wherever possible or if unavoidable whole engine(s)
387 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
388     policy and priority on thread level, set a minimum stack size for
389     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
390     threads simply inherited properties of starting thread instead of
391     setting their own policy and priority
392 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
393     main process did not wait for the stack trace process to finish
394     its output
395 persson 1248 - fixed some minor memory leaks
396 schoenebeck 1259 - reenabled assembly features support, at the moment only for
397     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
398 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
399     register, to avoid relocations in the text segment at runtime)
400 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
401 schoenebeck 947
402     * MIDI driver:
403     - dispatch bank select (MSB and LSB) messages
404    
405 schoenebeck 1049 * audio driver:
406     - the ALSA audio output driver parameters now reflect the correct
407     parameter value ranges for the respective selected sound card
408     (patch by Till Wimmer, a bit fixed and extended)
409    
410 persson 951 * Gigasampler format engine:
411     - if a filter is used and EG2 finishes before EG1, let the voice
412     die when EG2 has finished (this fixes a problem with clicks and
413     voice starvation for some gigs)
414 persson 1038 - playback is no longer disabled during instrument loading
415     - all notes playing on a channel that changes its instrument keep
416     playing with the old instrument until they get a note off
417     command
418 persson 1039 - EG fix: a release value of zero could cause noises or crash
419 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
420 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
421     above max sustain level, which means that there is a decay phase
422     even if sustain is 100%
423 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
424     noises or crashes
425 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
426 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
427     supplied to the configure script (fixes #46)
428 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
429     instead of a fix value
430 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
431     127 (solo mode) only kill voices if the respective mode really
432     changed
433 persson 951
434 schoenebeck 1244 * LSCP server:
435     - fixed compile time error for old Bison versions
436     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
437 schoenebeck 1245 - parser now supports extended ASCII character set
438     (up to ASCII code 255, i.e. includes now umlauts and accents)
439     - filename arguments in LSCP commands now allow to use escape
440     sequences, that is directly literal as one of: \', \", \\, \n, \r,
441     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
442     code value like \xf2) (fixes bug #24)
443 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
444     least one of their text-based parameters (i.e. name, description):
445     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
446     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
447     "SET DB_INSTRUMENT_DIRECTORY NAME",
448     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
449     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
450     "FIND DB_INSTRUMENT_DIRECTORIES"
451 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
452     occured, the unexpected character and the actually expected, possible
453     character(s), the latter only if less than 5 possibilities)
454 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
455     settings
456 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
457     of strings were treated as being one string containing commas
458     (fixes #57)
459 schoenebeck 1244
460 iliev 959 * Bug fixes:
461     - fixed crash occurring on certain LSCP scripts (Bug 39)
462 persson 1038 - another thread safety fix for lscp "load engine" and "set
463     channel audio output device"
464 iliev 1283 - fixed a crash which occurs when reassigning the same engine
465     on a sampler channel with connected MIDI device
466 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
467     device connected to a sampler channel to number less then or equal
468     to the index of the port to which the sampler channel is connected.
469 iliev 1296 - The previous bindings were not been disconnected when altering
470     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
471     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
472 iliev 1297 - The active stream/voice count statistic was incorrect.
473 iliev 1298 - notification events were not been sent for some sampler
474     channel changes
475 iliev 1305 - added default min and max values to restrict the number of allowed
476     audio output channels and MIDI input ports
477 iliev 1306 - the connection to the PCM interface is now closed when destroying
478     an audio output device
479 schoenebeck 1332 - files with slash in their path or filename could not be loaded
480 iliev 959
481 schoenebeck 1221 * test cases:
482     - updated and fixed (haven't been touched in a while)
483    
484 schoenebeck 937 Version 0.4.0 (24 November 2006)
485 persson 696
486 schoenebeck 697 * packaging changes:
487 capela 868 - changed deprecated copyright attribute to license; added ldconfig
488     to post-(un)install steps; added devel package for liblinuxsampler;
489     to linuxsampler.spec (RPM)
490 schoenebeck 697 - install necessary development header files for allowing 3rd party
491     applications to link against liblinuxsampler
492     - liblinuxsampler's API documentation can be generated with 'make docs'
493     (Doxygen required)
494 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
495     implementation (currently either an integer math solution or a
496     di-harmonic approximation), automatic detection can be overriden
497     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
498     configure script argument though (mandatory for cross-compilation)
499 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
500     provided some on his own (as CXXFLAGS)
501 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
502     messages
503 schoenebeck 852 - added compile time options to allow disabling the various audio and
504     MIDI drivers
505 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
506     (patch by Ebrahim Mayat)
507 schoenebeck 697
508 persson 696 * Gigasampler format engine:
509 schoenebeck 738 - extensive synthesis optimization
510     (reimplementation of EGs and LFO(s), removed synthesis parameter
511     prerendering and the synthesis parameter matrix in general, splitting
512     each audio fragment into subfragments now where each subfragment uses
513 persson 830 constant pitch and filter coefficients. The volume coefficient is
514     linearly interpolated inside a subfragment, unless
515     --disable-interpolate-volume is set.)
516 persson 696 - fine tuning of the EG modulation parameters
517 persson 729 - improved filter cutoff calculation by adding support for the
518     following gig parameters: Cutoff freq (used when no cutoff
519     controller is defined), Control invert, Minimum cutoff, Velocity
520 persson 791 curve and Velocity range. The keyboard tracking now scales
521     cutoff frequency instead of resonance.
522 persson 877 - added support for gig parameter Resonance.
523 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
524 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
525     which can be overridden with --enable-global-attenuation
526 persson 783 - EG fixes: made the length of "attack hold" stage more
527     accurate. Release stage can now start before attack stage
528 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
529     time now has a minimal value to prevent clicks.
530 persson 799 - fixed pitch changes larger than one octave
531 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
532     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
533     all modes can be altered via standard GM messages, that is CC5 for
534     altering portamento time, CC65 for enabling / disabling portamento
535     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
536 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
537     parameter) and crossfade
538 persson 831 - added support for the "attenuation controller threshold" gig
539     parameter
540 persson 832 - added smoothing of volume changes caused by control change
541     messages
542 persson 865 - sample loop parameters are now taken from the DimensionRegion
543     instead of the wave chunk
544     - fixed keyswitching for v3 gigs with a number of keyswitch splits
545     not equal to a power of two
546 persson 877 - reimplementation of the filter algorithm. The new filter is more
547     accurate and supports all gig filter types, including bandreject
548     and lowpass turbo.
549 persson 903 - real support for 24 bit samples - samples are not truncated to
550     16 bits anymore
551     - support for aftertouch (channel pressure, not polyphonic
552     aftertouch)
553 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
554     amplifying from 0)
555 persson 696
556 schoenebeck 711 * LSCP server:
557     - fixed application exit on broken pipe error (fixes bug #20)
558 iliev 793 - fixed the notification messages delay due to lack of
559     network activity (fixes bug #26)
560 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
561     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
562 schoenebeck 711
563 schoenebeck 838 * audio driver:
564     - added aRts audio output driver (by no means RT safe)
565    
566 schoenebeck 775 * MIDI driver:
567     - fixed legacy sysex code which caused dispatching of MIDI SysEx
568     messages several times instead of once
569 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
570     for events (i.e. for offline rendering based MIDI drivers)
571 persson 922 - added checks for bad MIDI data
572 schoenebeck 775
573 schoenebeck 900 * linuxsampler application:
574     - show available sampler engine types on startup
575    
576 schoenebeck 705 * general changes:
577     - support for muting sampler channels and solo mode of the same, two new
578     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
579     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
580     introduced for this, the behavior is the same like on a mixer console
581 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
582     --enable-process-muted-channels which can be used to enable the
583     processing of muted channels.
584 iliev 777 - support for sostenuto pedal
585 iliev 779 - support for monitoring the total number of active voices
586 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
587     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
588 persson 835 - fixed some memory management errors
589 persson 841 - fixed some concurrency problems that could lead to crashes when
590     LSCP commands were executed
591 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
592     sampler channel (fixes bug #36)
593 schoenebeck 705
594 schoenebeck 692 Version 0.3.3 (15 July 2005)
595 schoenebeck 686
596     * packaging changes:
597     - fixed compilation with gcc 4.0
598    
599 schoenebeck 687 * Gigasampler format engine:
600     - LFO preprocessing was performed even though the respective LFO was
601     disabled by the instrument patch (minor efficiency fix)
602 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
603     for volume ramp downs in the same fragment (needed for current voice
604     stealing implementation) then simply inform the user with a warning
605     about possible click sounds and reduce the volume ramp down
606     appropriately instead of cancelling the audio device connection
607 schoenebeck 687
608 schoenebeck 677 Version 0.3.2 (24 June 2005)
609 schoenebeck 609
610     * packaging changes:
611     - updated autotools build files to compile on OS X
612     (conditional compilation of CoreMIDI and MidiShare drivers)
613 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
614     './configure --disable-asm' (definitely not recommended)
615 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
616     - require automake (>= 1.5) for 'make -f Makefile.cvs'
617     (due to 'dist-bzip2' automake option)
618 schoenebeck 649
619     * Gigasampler format engine:
620     - support for the gig parameters for "release velocity response" curves
621     - fine tuning of the EGADSR envelope
622     - volume of release triggered samples now depends on note-on velocity,
623     note length and gig parameter "release trigger decay" instead of
624     note-off velocity.
625 schoenebeck 663 - revised voice stealing
626     (fixes crash and endless loop caused by voice stealing)
627 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
628 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
629     instead of when the respective voice is actually launched
630     (fixes undefined behavior if stolen voices belonged to a key group -
631     this case was followed by a "killed voice survived" error message)
632 schoenebeck 669 - fixed minor issue with null/silence samples
633     (those stole voices even though they don't need a voice at all which
634     resulted in "voice stealing didn't work out" messages)
635 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
636     instrument or audio output device change
637 schoenebeck 654
638 schoenebeck 620 * LSCP server:
639 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
640 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
641 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
642 schoenebeck 609
643 schoenebeck 668 * linuxsampler application:
644     - added command line parameters --lscp-addr and --lscp-port to override
645     default IP address and port of LSCP server
646    
647 schoenebeck 579 Version 0.3.1 (24 May 2005)
648    
649     * initial release
