* VST bugfix: If the host called resume() before and after changing
  sample rate or block size, the number of channels was incorrectly
  set to two. This caused silence in Cubase 5.
* removed compiler warnings

1 schoenebeck 1993 Version CVS HEAD (?)
2

4     - Refactoring: moved the independent code from
5     the Gigasampler format engine to base classes
6    
7 persson 2043 * Gigasampler format engine:
8     - implemented the "round robin keyboard" dimension
9     - fixed round robin and random dimensions for cases when number of
10     dimension zones is not a power of two
11     - made round robin use a counter for each region instead of each
12     key
13    
14 iliev 2012 * SFZ format engine
15     - Initial implementation (not usable yet)
16

23 persson 2045 - VST bugfix: If the host called resume() before and after
24     changing sample rate or block size, the number of channels was
25     incorrectly set to two. This caused silence in Cubase 5.
26 schoenebeck 1993
27     * MIDI driver:
28     - ALSA MIDI driver supports now "NAME" device parameter, for overriding

39 schoenebeck 1599
40 schoenebeck 1639 * packaging changes:
41     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
42     causing e.g. the libgig test to fail when

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

83     multi-core and multi-cpu systems
84 schoenebeck 1800 - maximum voices and disk streams can now be altered at runtime
85 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
86 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
87     be switched on by command line option "--stacktrace" (the automatic
88     stacktrace mechanism seems to be broken on most systems at the moment)
89 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
90     a pointer to the launched InstrumentEditor object
91 schoenebeck 1876 - added optional 3rd party user data parameter for following
92     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
93     InstrumentEditor::Launch(),

100     gigedit on systems with other GTK versions installed)
101 schoenebeck 1601
102 schoenebeck 1599 * audio driver:
103     - removed the nonsense audio channel constraint (which was hard coded to
104     max. 100 audio channels) for most audio drivers
105 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
106     opposed to the LSCP specs
107 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
108     reflected the wrong value

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

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