* added channel routing, fxsends and midi maps to the settings stored
  in the plugin state

1 schoenebeck 1599 Version CVS HEAD (?)
2    
3 schoenebeck 1639 * packaging changes:
4     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
5     causing e.g. the libgig test to fail when
6     "./configure --disable-jack-driver" was used
7     (patch by Alexis Ballier)
8 persson 1713 - fixed compilation with gcc 4.3
9 persson 1792 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
10 persson 1794 - fixed configure so it detects x86_64 (#107)
11 persson 1808 - fixes for building with newer MinGW versions
12     - fix for building with bison 2.4 (#111)
13 persson 1842 - fixed building with libgig installed in a non-standard directory
14 persson 1895 - minor fix in configure for mmsystem.h detection on MinGW
15 persson 1897 - Windows: look for editor plugins and Fantasia using base
16     directory of liblinuxsampler dll
17 persson 1899 - configure script fix: removed unconditional use of SSE
18 schoenebeck 1639
19 schoenebeck 1601 * general changes:
20     - bugfix: on some POSIX systems instrument editor plugins refused to
21     load as we used a non-portable Linux specific struct field
22     (fixes bug #70, patch by Ronald Baljeu)
23 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
24     plugin DLL on Windows systems failed
25 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded
26     - optimized the SynchronizedConfig class so it doesn't wait
27     unnecessarily long after an update
28 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
29     events (e.g. to highlight the pressed keys on the virtual keyboard
30     of gigedit)
31 schoenebeck 1659 - added support for triggering notes by instrument editors (see above)
32 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
33 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation
34     is only used by very few systems, most pick the int math
35     implementation, which is usually faster)
36 persson 1748 - fixes for audio drivers with varying buffer sizes
37 persson 1777 - experimental support for running LinuxSampler as a DSSI, LV2 and
38     VST plugin
39 iliev 1789 - notification events for stream/voice count statistics are now sent
40     only when there are actual changes
41 persson 1790 - added memory ordering constraints to improve stability on
42     multi-core and multi-cpu systems
43 schoenebeck 1800 - maximum voices and disk streams can now be altered at runtime
44 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
45 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
46     be switched on by command line option "--stacktrace" (the automatic
47     stacktrace mechanism seems to be broken on most systems at the moment)
48 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
49     a pointer to the launched InstrumentEditor object
50 schoenebeck 1876 - added optional 3rd party user data parameter for following
51     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
52     InstrumentEditor::Launch(),
53     InstrumentManager::LaunchInstrumentEditor()
54 persson 1887 - theoretical fix: made SynchronizedConfig follow C++0x memory
55     model more strictly
56 persson 1895 - fixes for using large audio device buffers
57 schoenebeck 1601
58 schoenebeck 1599 * audio driver:
59     - removed the nonsense audio channel constraint (which was hard coded to
60     max. 100 audio channels) for most audio drivers
61 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
62     opposed to the LSCP specs
63 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
64     reflected the wrong value
65 persson 1644 - fixed a memory management bug in ASIO driver
66 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used
67 persson 1777 - JACK: use jack_client_open instead of the deprecated

69 iliev 1829 - added (experimental) CoreAudio driver
70 persson 1888 - applied old fixes to the ASIO driver that were included in the
71     previous binary release but accidentally never committed to CVS
72     (fixes #117)
73 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
74     win64)
75 persson 1895 - VST: added support for sample rate and buffer size changes
76     - VST: close editor (Fantasia) when the VST is removed
77 persson 1908 - VST: avoid opening Fantasia more than once for each VST instance
78     - VST: export main function as "main" on Linux too (fix for
79     energyXT)
80 persson 1917 - VST: changed number of output channels from one stereo to 16
81     stereo
82 persson 1922 - added channel routing, fxsends and midi maps to the settings
83     stored in the plugin state
84 schoenebeck 1599
85 persson 1651 * MIDI driver:
86     - added JACK MIDI driver
87 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
88     want to (mis)use it for some purpose ("fixed" in all current MIDI
89     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
90 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
91 persson 1887 CoreMidi or AU
92 persson 1889 - fixed mingw-w64 compilation error in MME driver
93 persson 1651
94 schoenebeck 1604 * instruments database:
95 iliev 1603 - avoid time consuming samples scanning when adding instruments
96     to the instruments database
97 iliev 1727 - added support for handling lost files in the instruments database
98 iliev 1781 - Implemented option for adding instruments in separate directories
99     in the instruments database
100     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
101 persson 1908 - work-around for missing fnmatch function on Windows to make
102     instrument database compilable
103 senoner 1910 - added instrument database support on Windows
104 senoner 1911 works with both standalone mode and VST plugin.
105     the instruments DB file is located in
106     %USERPROFILE%\.linuxsampler\instruments.db which allows different
107     databases for each windows user
108 senoner 1912 if no DB is present it automatically creates the .linuxsampler subdir
109     and then creates an empty DB
110 iliev 1603
111 persson 1644 * Gigasampler format engine:
112     - fixed a memory leak that could happen when a channel was deleted
113     while notes were playing
114 persson 1646 - made it possible to load an instrument even if the audio thread
115     isn't running
116 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
117     enough for piano gigs with pedal noise samples
118 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
119     respective FX send MIDI controller was used
120 schoenebeck 1724 - added support for GM global device volume SysEx message
121 schoenebeck 1762 (can be selected at compile time to either apply globally to the
122     whole sampler [default] or only to the sampler channels that are
123     connected to the respective MIDI input port the SysEx message arrived
124     on)
125 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
126     sometimes wrongly killed in the same buffer, causing no sound to
127     be played
128 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
129     which is usally used to switch a part between chromatic sounds and
130     drumkit sounds (as opposed to their common default setting of MIDI
131     part 10 being a drumkit part and all other ones chromatic parts), in
132     LS however one can switch between the first 16 MIDI instrument maps
133     defined for the sampler
134 persson 1764 - made it possible to create multiple sample channels even if the
135     audio thread isn't running
136 persson 1844 - fixed crash when removing channel with active voices (#116)
137 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
138     un-cache the respective sample if it's really not used by any
139     sampler engine anymore
140     - re-cache samples in case they were changed by an instrument editor,
141     e.g. when a sample was added while playing (#82)
142 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
143     same time stamp as the voice's note-on event and occured both in the
144     same audio fragment cycle (fixes bug #112)
145 persson 1858 - added support for the "fine tune" and "pitch bend range"
146     instrument-level gig parameters
147     - fixed minor artifacts in pitch bend handling
148 schoenebeck 1860 - added support for GS Reset SysEx message
149 persson 1862 - allow gig files to use unlimited downward pitch shifting
150     - added a limit check for upward pitch shifting
151 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
152     note was silent
153 persson 1644
154 schoenebeck 1687 * LSCP server:
155     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
156     react on MIDI data arriving on certain sampler channels (so far only
157     Note-On and Note-Off events are sent via this LSCP event)
158 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
159     react on MIDI data arriving on certain MIDI input devices (so far only
160     Note-On and Note-Off events are sent via this LSCP event)
161 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
162     SET DB_INSTRUMENT FILE_PATH
163 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
164     frontends to send MIDI messages to specific sampler channel
165     - added two additional fields to GET FILE INSTRUMENT INFO command -
166     KEY_BINDINGS and KEYSWITCH_BINDINGS
167 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
168     was incorrect
169 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
170 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
171     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
172     be triggered respectively
173     - added new LSCP command "SET STREAMS" to globally alter the maximum
174     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
175     which will be triggered respectively
176 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
177     a gigedit file dialog is opened)
178 iliev 1848 - close all connections when LSCPServer is deleted
179 iliev 1882 - hard close of all sockets on exit
180 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
181     driver
182 schoenebeck 1687
183 iliev 1761 * Bug fixes:
184     - fixed a crash which occurs when removing a sampler channel waiting
185     to start instrument loading after another channel
186 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
187     instrument loading in progress (bug #113)
188 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
189     instrument with PERSISTENT load mode
190 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
191     - fixed memory leaks when issuing the following LSCP commands:
192     GET AUDIO_OUTPUT_DRIVER INFO
193     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
194     GET MIDI_INPUT_DRIVER INFO
195     GET MIDI_INPUT_DRIVER_PARAMETER INFO
196     - fixed possible compilation error when sqlite is not present
197 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
198 iliev 1847 - fixed crash when changing the audio output device of a sampler
199     channel with loaded instrument and start playing notes
200 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
201 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
202     PowerPC, which probably could cause crashes on that platform
203 persson 1889 - fixed a memory management error which could cause a crash when a
204     plugin was unloaded
205 persson 1896 - bugfix: two private structs had the same name, which could cause
206     problems if the linker chose the wrong constructor
207 iliev 1761
208    
209 schoenebeck 1560 Version 0.5.1 (6 December 2007)
210 schoenebeck 1454
211     * packaging changes:
212     - added autoconf checks for pthread library
213     - added autoconf check for pthread bug found on certain NPTL-enabled
214     glibc versions (see Gentoo bug report #194076)
215 senoner 1502 - added autoconf checks for MS Windows
216 schoenebeck 1454
217 persson 1455 * general changes:
218     - bugfix: the thread used by an editor plugin didn't die when the
219     editor closed
220 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
221     out all the space. operator--() did not apply size_mask after
222     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
223     order to avoid problems with the _NonVolatileReader functions.
224     - bugfix: Stream.h: added a missing divide by BytesPerSample in
225     GetWriteSpace(). Since this function is currently only used in
226     the stream's qsort() compare function, it didn't trigger any
227     bugs.
228     - Resampler.h, Synthesizer.h: cubic interpolation now works in
229     24bit mode too. Faster method to read 24bit words on little
230     endian machines (x86): replaced 3 byte reads + shifts with a 1
231     unaligned 32bit read and shift
232     - experimental support for MS Windows (MIDI input via MME, AUDIO
233     output via ASIO)
234     - made handling of SIGINT signal (Ctrl-C) a bit more robust
235 iliev 1541 - support for monitoring the total number of active disk streams
236     (new LSCP commands: GET TOTAL_STREAM_COUNT,
237     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
238 persson 1455
239 senoner 1500 * AUDIO driver:
240 persson 1534 - added Windows ASIO low latency audio driver
241 senoner 1500
242 senoner 1485 * MIDI driver:
243 schoenebeck 1495 - added MME Windows MIDI driver
244 senoner 1485
245 schoenebeck 1471 * LSCP server:
246     - added support for Windows style path / filenames, however with
247     forward slash path separators instead of backslash
248     (i.e. "C:/foo/bar.gig")
249 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
250     apostrophes as well
251 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
252     "LIST FILE INSTRUMENTS <file>" and
253     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
254     about an arbitrary instrument file on the system where the sampler is
255     running on
256 schoenebeck 1471
257 schoenebeck 1424 Version 0.5.0 (15 October 2007)
258 schoenebeck 947
259 schoenebeck 1065 * packaging changes:
260 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
261     API header files anymore
262 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
263     the Doxygen API documentation (explicitly listed in Doxyfile.in)
264 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
265     capable to execute our autoconf environment, thus no need anymore
266     to maintain the compile time configuration file (osx/version.h) for
267     OSX manually (patch by Toshi Nagata)
268 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
269     parameters
270 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
271     C++ API header files, all implementation internal global definitions
272     are now in global_private.h
273     - atomic.h is not exposed to the C++ API anymore
274     - no need to include config.h anymore for using LS's API header files
275     - fixed warnings in API doc generation
276 schoenebeck 1065
277 schoenebeck 947 * general changes:
278     - replaced the old, confusing MIDI program change mechanism by a
279     flexible MIDI instrument mapper which allows to map arbitrary
280 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
281 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
282     loaded on the respective channel when such MIDI program change
283     messages arrive, beside that, each entry allows to define a life-time
284     strategy for the instrument, so the user can define whether the
285     instrument should i.e. be permanently loaded (to be able to switch
286     quickly among sounds) or i.e. loaded just on demand when the
287     respective program change arrives (to safe RAM space), as well as a
288     global volume factor for each entry, so the user can adjust the volume
289     dynamic of his mapped instrument collection without having to modify
290 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
291     MIDI instrument maps and assign each sampler channel individually
292     a certain map, so that i.e. separation of normal instruments and
293     drumkits is possible
294 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
295     MIDI instrument maps, MIDI instruments, FX sends, global volume.
296 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
297     due to a constant size RingBuffer FIFO which is now replaced by a
298     dynamic (unlimited) size std::list FIFO
299 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
300     output channels for being processed by external effect processors
301     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
302     controllers
303 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
304 iliev 1130 - Implemented new, improved notification system
305 schoenebeck 1149 - fixed compilation errors regarding OSX
306     (patch by Toshi Nagata)
307 iliev 1161 - implemented instruments database
308 iliev 1345 - added support for escape sequences to the instruments database
309 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
310     within the sampler's process (by using instrument editor plugins),
311     you'll notice the new "Registered instrument editors:" message on
312 schoenebeck 1407 startup, added a new LSCP command:
313     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
314 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
315     given sampler channel, the plugin path can be overridden at compile
316     time with ./configure --enable-plugin-dir=/some/dir
317 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
318     in the sampler's process to safely edit instruments while playing
319     without a crash (hopefully) by either suspending single regions
320     wherever possible or if unavoidable whole engine(s)
321 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
322     policy and priority on thread level, set a minimum stack size for
323     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
324     threads simply inherited properties of starting thread instead of
325     setting their own policy and priority
326 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
327     main process did not wait for the stack trace process to finish
328     its output
329 persson 1248 - fixed some minor memory leaks
330 schoenebeck 1259 - reenabled assembly features support, at the moment only for
331     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
332 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
333     register, to avoid relocations in the text segment at runtime)
334 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
335 schoenebeck 947
336     * MIDI driver:
337     - dispatch bank select (MSB and LSB) messages
338    
339 schoenebeck 1049 * audio driver:
340     - the ALSA audio output driver parameters now reflect the correct
341     parameter value ranges for the respective selected sound card
342     (patch by Till Wimmer, a bit fixed and extended)
343    
344 persson 951 * Gigasampler format engine:
345     - if a filter is used and EG2 finishes before EG1, let the voice
346     die when EG2 has finished (this fixes a problem with clicks and
347     voice starvation for some gigs)
348 persson 1038 - playback is no longer disabled during instrument loading
349     - all notes playing on a channel that changes its instrument keep
350     playing with the old instrument until they get a note off
351     command
352 persson 1039 - EG fix: a release value of zero could cause noises or crash
353 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
354 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
355     above max sustain level, which means that there is a decay phase
356     even if sustain is 100%
357 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
358     noises or crashes
359 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
360 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
361     supplied to the configure script (fixes #46)
362 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
363     instead of a fix value
364 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
365     127 (solo mode) only kill voices if the respective mode really
366     changed
367 persson 951
368 schoenebeck 1244 * LSCP server:
369     - fixed compile time error for old Bison versions
370     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
371 schoenebeck 1245 - parser now supports extended ASCII character set
372     (up to ASCII code 255, i.e. includes now umlauts and accents)
373     - filename arguments in LSCP commands now allow to use escape
374     sequences, that is directly literal as one of: \', \", \\, \n, \r,
375     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
376     code value like \xf2) (fixes bug #24)
377 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
378     least one of their text-based parameters (i.e. name, description):
379     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
380     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
381     "SET DB_INSTRUMENT_DIRECTORY NAME",
382     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
383     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
384     "FIND DB_INSTRUMENT_DIRECTORIES"
385 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
386     occured, the unexpected character and the actually expected, possible
387     character(s), the latter only if less than 5 possibilities)
388 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
389     settings
390 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
391     of strings were treated as being one string containing commas
392     (fixes #57)
393 schoenebeck 1244
394 iliev 959 * Bug fixes:
395     - fixed crash occurring on certain LSCP scripts (Bug 39)
396 persson 1038 - another thread safety fix for lscp "load engine" and "set
397     channel audio output device"
398 iliev 1283 - fixed a crash which occurs when reassigning the same engine
399     on a sampler channel with connected MIDI device
400 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
401     device connected to a sampler channel to number less then or equal
402     to the index of the port to which the sampler channel is connected.
403 iliev 1296 - The previous bindings were not been disconnected when altering
404     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
405     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
406 iliev 1297 - The active stream/voice count statistic was incorrect.
407 iliev 1298 - notification events were not been sent for some sampler
408     channel changes
409 iliev 1305 - added default min and max values to restrict the number of allowed
410     audio output channels and MIDI input ports
411 iliev 1306 - the connection to the PCM interface is now closed when destroying
412     an audio output device
413 schoenebeck 1332 - files with slash in their path or filename could not be loaded
414 iliev 959
415 schoenebeck 1221 * test cases:
416     - updated and fixed (haven't been touched in a while)
417    
418 schoenebeck 937 Version 0.4.0 (24 November 2006)
419 persson 696
420 schoenebeck 697 * packaging changes:
421 capela 868 - changed deprecated copyright attribute to license; added ldconfig
422     to post-(un)install steps; added devel package for liblinuxsampler;
423     to linuxsampler.spec (RPM)
424 schoenebeck 697 - install necessary development header files for allowing 3rd party
425     applications to link against liblinuxsampler
426     - liblinuxsampler's API documentation can be generated with 'make docs'
427     (Doxygen required)
428 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
429     implementation (currently either an integer math solution or a
430     di-harmonic approximation), automatic detection can be overriden
431     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
432     configure script argument though (mandatory for cross-compilation)
433 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
434     provided some on his own (as CXXFLAGS)
435 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
436     messages
437 schoenebeck 852 - added compile time options to allow disabling the various audio and
438     MIDI drivers
439 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
440     (patch by Ebrahim Mayat)
441 schoenebeck 697
442 persson 696 * Gigasampler format engine:
443 schoenebeck 738 - extensive synthesis optimization
444     (reimplementation of EGs and LFO(s), removed synthesis parameter
445     prerendering and the synthesis parameter matrix in general, splitting
446     each audio fragment into subfragments now where each subfragment uses
447 persson 830 constant pitch and filter coefficients. The volume coefficient is
448     linearly interpolated inside a subfragment, unless
449     --disable-interpolate-volume is set.)
450 persson 696 - fine tuning of the EG modulation parameters
451 persson 729 - improved filter cutoff calculation by adding support for the
452     following gig parameters: Cutoff freq (used when no cutoff
453     controller is defined), Control invert, Minimum cutoff, Velocity
454 persson 791 curve and Velocity range. The keyboard tracking now scales
455     cutoff frequency instead of resonance.
456 persson 877 - added support for gig parameter Resonance.
457 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
458 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
459     which can be overridden with --enable-global-attenuation
460 persson 783 - EG fixes: made the length of "attack hold" stage more
461     accurate. Release stage can now start before attack stage
462 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
463     time now has a minimal value to prevent clicks.
464 persson 799 - fixed pitch changes larger than one octave
465 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
466     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
467     all modes can be altered via standard GM messages, that is CC5 for
468     altering portamento time, CC65 for enabling / disabling portamento
469     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
470 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
471     parameter) and crossfade
472 persson 831 - added support for the "attenuation controller threshold" gig
473     parameter
474 persson 832 - added smoothing of volume changes caused by control change
475     messages
476 persson 865 - sample loop parameters are now taken from the DimensionRegion
477     instead of the wave chunk
478     - fixed keyswitching for v3 gigs with a number of keyswitch splits
479     not equal to a power of two
480 persson 877 - reimplementation of the filter algorithm. The new filter is more
481     accurate and supports all gig filter types, including bandreject
482     and lowpass turbo.
483 persson 903 - real support for 24 bit samples - samples are not truncated to
484     16 bits anymore
485     - support for aftertouch (channel pressure, not polyphonic
486     aftertouch)
487 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
488     amplifying from 0)
489 persson 696
490 schoenebeck 711 * LSCP server:
491     - fixed application exit on broken pipe error (fixes bug #20)
492 iliev 793 - fixed the notification messages delay due to lack of
493     network activity (fixes bug #26)
494 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
495     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
496 schoenebeck 711
497 schoenebeck 838 * audio driver:
498     - added aRts audio output driver (by no means RT safe)
499    
500 schoenebeck 775 * MIDI driver:
501     - fixed legacy sysex code which caused dispatching of MIDI SysEx
502     messages several times instead of once
503 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
504     for events (i.e. for offline rendering based MIDI drivers)
505 persson 922 - added checks for bad MIDI data
506 schoenebeck 775
507 schoenebeck 900 * linuxsampler application:
508     - show available sampler engine types on startup
509    
510 schoenebeck 705 * general changes:
511     - support for muting sampler channels and solo mode of the same, two new
512     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
513     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
514     introduced for this, the behavior is the same like on a mixer console
515 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
516     --enable-process-muted-channels which can be used to enable the
517     processing of muted channels.
518 iliev 777 - support for sostenuto pedal
519 iliev 779 - support for monitoring the total number of active voices
520 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
521     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
522 persson 835 - fixed some memory management errors
523 persson 841 - fixed some concurrency problems that could lead to crashes when
524     LSCP commands were executed
525 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
526     sampler channel (fixes bug #36)
527 schoenebeck 705
528 schoenebeck 692 Version 0.3.3 (15 July 2005)
529 schoenebeck 686
530     * packaging changes:
531     - fixed compilation with gcc 4.0
532    
533 schoenebeck 687 * Gigasampler format engine:
534     - LFO preprocessing was performed even though the respective LFO was
535     disabled by the instrument patch (minor efficiency fix)
536 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
537     for volume ramp downs in the same fragment (needed for current voice
538     stealing implementation) then simply inform the user with a warning
539     about possible click sounds and reduce the volume ramp down
540     appropriately instead of cancelling the audio device connection
541 schoenebeck 687
542 schoenebeck 677 Version 0.3.2 (24 June 2005)
543 schoenebeck 609
544     * packaging changes:
545     - updated autotools build files to compile on OS X
546     (conditional compilation of CoreMIDI and MidiShare drivers)
547 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
548     './configure --disable-asm' (definitely not recommended)
549 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
550     - require automake (>= 1.5) for 'make -f Makefile.cvs'
551     (due to 'dist-bzip2' automake option)
552 schoenebeck 649
553     * Gigasampler format engine:
554     - support for the gig parameters for "release velocity response" curves
555     - fine tuning of the EGADSR envelope
556     - volume of release triggered samples now depends on note-on velocity,
557     note length and gig parameter "release trigger decay" instead of
558     note-off velocity.
559 schoenebeck 663 - revised voice stealing
560     (fixes crash and endless loop caused by voice stealing)
561 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
562 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
563     instead of when the respective voice is actually launched
564     (fixes undefined behavior if stolen voices belonged to a key group -
565     this case was followed by a "killed voice survived" error message)
566 schoenebeck 669 - fixed minor issue with null/silence samples
567     (those stole voices even though they don't need a voice at all which
568     resulted in "voice stealing didn't work out" messages)
569 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
570     instrument or audio output device change
571 schoenebeck 654
572 schoenebeck 620 * LSCP server:
573 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
574 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
575 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
576 schoenebeck 609
577 schoenebeck 668 * linuxsampler application:
578     - added command line parameters --lscp-addr and --lscp-port to override
579     default IP address and port of LSCP server
580    
581 schoenebeck 579 Version 0.3.1 (24 May 2005)
582    
583     * initial release
