* command line option '--profile' is currently disabled, since the
  respective profiling code is currently broken

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 iliev 2012
9 persson 2043 * Gigasampler format engine:
10     - implemented the "round robin keyboard" dimension
11     - fixed round robin and random dimensions for cases when number of
12     dimension zones is not a power of two
13     - made round robin use a counter for each region instead of each
14     key
15    
16 schoenebeck 2047 * SFZ format engine:
17 iliev 2012 - Initial implementation (not usable yet)
18    
19 schoenebeck 2047 * SoundFont format engine:
20 iliev 2012 - Initial implementation (not usable yet)
21    
22     * Host plugins:
23 schoenebeck 1993 - AU bugfix: failed to destroy its audio/MIDI devices
24 iliev 1994 - Listen to all interfaces on Mac OS X (INADDR_ANY)
25 persson 2045 - VST bugfix: If the host called resume() before and after
26     changing sample rate or block size, the number of channels was
27     incorrectly set to two. This caused silence in Cubase 5.
28 schoenebeck 1993
29     * MIDI driver:
30     - ALSA MIDI driver supports now "NAME" device parameter, for overriding
31     the ALSA sequencer client name
32

41 schoenebeck 1599
42 schoenebeck 1639 * packaging changes:
43     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
44     causing e.g. the libgig test to fail when
45     "./configure --disable-jack-driver" was used
46     (patch by Alexis Ballier)
47 persson 1713 - fixed compilation with gcc 4.3
48 persson 1792 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)

55 schoenebeck 1928 directory of liblinuxsampler dll (look in the same directory and one
56     directory above)
57 persson 1899 - configure script fix: removed unconditional use of SSE
58 persson 1923 - fixed building with sqlite installed in a non-standard directory
59 persson 1931 - when cross-compiling, don't try to create instruments.db

61 schoenebeck 1639
62 schoenebeck 1601 * general changes:
63     - bugfix: on some POSIX systems instrument editor plugins refused to
64     load as we used a non-portable Linux specific struct field
65     (fixes bug #70, patch by Ronald Baljeu)
66 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
67     plugin DLL on Windows systems failed
68 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded
69     - optimized the SynchronizedConfig class so it doesn't wait
70     unnecessarily long after an update
71 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
72     events (e.g. to highlight the pressed keys on the virtual keyboard
73     of gigedit)
74 schoenebeck 1659 - added support for triggering notes by instrument editors (see above)
75 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
76 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation
77     is only used by very few systems, most pick the int math
78     implementation, which is usually faster)
79 persson 1748 - fixes for audio drivers with varying buffer sizes
80 persson 1777 - experimental support for running LinuxSampler as a DSSI, LV2 and
81     VST plugin
82 iliev 1789 - notification events for stream/voice count statistics are now sent
83     only when there are actual changes

85     multi-core and multi-cpu systems
86 schoenebeck 1800 - maximum voices and disk streams can now be altered at runtime
87 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
88 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
89     be switched on by command line option "--stacktrace" (the automatic
90     stacktrace mechanism seems to be broken on most systems at the moment)
91 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
92     a pointer to the launched InstrumentEditor object
93 schoenebeck 1876 - added optional 3rd party user data parameter for following
94     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
95     InstrumentEditor::Launch(),
96     InstrumentManager::LaunchInstrumentEditor()
97 persson 1887 - theoretical fix: made SynchronizedConfig follow C++0x memory
98     model more strictly
99 persson 1895 - fixes for using large audio device buffers
100 persson 1951 - Windows: add the installation directory to the DLL search path

102     gigedit on systems with other GTK versions installed)
103 schoenebeck 1601
104 schoenebeck 1599 * audio driver:
105     - removed the nonsense audio channel constraint (which was hard coded to
106     max. 100 audio channels) for most audio drivers
107 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
108     opposed to the LSCP specs
109 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
110     reflected the wrong value
111 persson 1644 - fixed a memory management bug in ASIO driver
112 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used

114 persson 1748 jack_client_new
115 iliev 1829 - added (experimental) CoreAudio driver
116 persson 1888 - applied old fixes to the ASIO driver that were included in the
117     previous binary release but accidentally never committed to CVS
118     (fixes #117)
119 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
120     win64)
121 persson 1895 - VST: added support for sample rate and buffer size changes
122     - VST: close editor (Fantasia) when the VST is removed
123 persson 1908 - VST: avoid opening Fantasia more than once for each VST instance
124     - VST: export main function as "main" on Linux too (fix for
125     energyXT)

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