11 schoenebeck 1599
12 schoenebeck 1639 * packaging changes:
13     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
14     causing e.g. the libgig test to fail when
15     "./configure --disable-jack-driver" was used
16     (patch by Alexis Ballier)

23 persson 1895 - minor fix in configure for mmsystem.h detection on MinGW
24 persson 1897 - Windows: look for editor plugins and Fantasia using base
25 schoenebeck 1928 directory of liblinuxsampler dll (look in the same directory and one
26     directory above)
27 persson 1899 - configure script fix: removed unconditional use of SSE
28 persson 1923 - fixed building with sqlite installed in a non-standard directory
29 persson 1931 - when cross-compiling, don't try to create instruments.db
30     - fix for new mingw-w64 version, which has usleep
31 schoenebeck 1639
32 schoenebeck 1601 * general changes:
33     - bugfix: on some POSIX systems instrument editor plugins refused to
34     load as we used a non-portable Linux specific struct field
35     (fixes bug #70, patch by Ronald Baljeu)
36 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
37     plugin DLL on Windows systems failed
38 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded
39     - optimized the SynchronizedConfig class so it doesn't wait
40     unnecessarily long after an update
41 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
42     events (e.g. to highlight the pressed keys on the virtual keyboard
43     of gigedit)
44 schoenebeck 1659 - added support for triggering notes by instrument editors (see above)
45 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
46 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation
47     is only used by very few systems, most pick the int math
48     implementation, which is usually faster)
49 persson 1748 - fixes for audio drivers with varying buffer sizes
50 persson 1777 - experimental support for running LinuxSampler as a DSSI, LV2 and
51     VST plugin
52 iliev 1789 - notification events for stream/voice count statistics are now sent

55     multi-core and multi-cpu systems
56 schoenebeck 1800 - maximum voices and disk streams can now be altered at runtime
57 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
58 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
59     be switched on by command line option "--stacktrace" (the automatic
60     stacktrace mechanism seems to be broken on most systems at the moment)
61 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
62     a pointer to the launched InstrumentEditor object
63 schoenebeck 1876 - added optional 3rd party user data parameter for following
64     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
65     InstrumentEditor::Launch(),
66     InstrumentManager::LaunchInstrumentEditor()
67 persson 1887 - theoretical fix: made SynchronizedConfig follow C++0x memory
68     model more strictly
69 persson 1895 - fixes for using large audio device buffers
70 persson 1951 - Windows: add the installation directory to the DLL search path
71     when loading an editor plugin (solves problems with VST and
72     gigedit on systems with other GTK versions installed)
73 schoenebeck 1601
74 schoenebeck 1599 * audio driver:
75     - removed the nonsense audio channel constraint (which was hard coded to
76     max. 100 audio channels) for most audio drivers
77 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
78     opposed to the LSCP specs
79 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
80     reflected the wrong value
81 persson 1644 - fixed a memory management bug in ASIO driver
82 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used

84 persson 1748 jack_client_new
85 iliev 1829 - added (experimental) CoreAudio driver
86 persson 1888 - applied old fixes to the ASIO driver that were included in the
87     previous binary release but accidentally never committed to CVS
88     (fixes #117)
89 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
90     win64)
91 persson 1895 - VST: added support for sample rate and buffer size changes
92     - VST: close editor (Fantasia) when the VST is removed
93 persson 1908 - VST: avoid opening Fantasia more than once for each VST instance
94     - VST: export main function as "main" on Linux too (fix for

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