29 schoenebeck 1599
30 schoenebeck 1639 * packaging changes:
31     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

52     load as we used a non-portable Linux specific struct field
53     (fixes bug #70, patch by Ronald Baljeu)
54 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
55     plugin DLL on Windows systems failed
56 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded
57     - optimized the SynchronizedConfig class so it doesn't wait
58     unnecessarily long after an update
59 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off

63 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
64 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation
65     is only used by very few systems, most pick the int math
66     implementation, which is usually faster)
67 persson 1748 - fixes for audio drivers with varying buffer sizes
68 persson 1777 - experimental support for running LinuxSampler as a DSSI, LV2 and
69     VST plugin
70 iliev 1789 - notification events for stream/voice count statistics are now sent

75 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
76 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
77     be switched on by command line option "--stacktrace" (the automatic
78     stacktrace mechanism seems to be broken on most systems at the moment)
79 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
80     a pointer to the launched InstrumentEditor object
81 schoenebeck 1876 - added optional 3rd party user data parameter for following
82     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
83     InstrumentEditor::Launch(),
84     InstrumentManager::LaunchInstrumentEditor()
85 persson 1887 - theoretical fix: made SynchronizedConfig follow C++0x memory
86     model more strictly
87 persson 1895 - fixes for using large audio device buffers
88 persson 1951 - Windows: add the installation directory to the DLL search path

90     gigedit on systems with other GTK versions installed)
91 schoenebeck 1601
92 schoenebeck 1599 * audio driver:
93     - removed the nonsense audio channel constraint (which was hard coded to
94     max. 100 audio channels) for most audio drivers
95 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
96     opposed to the LSCP specs
97 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
98     reflected the wrong value

102 persson 1748 jack_client_new
103 iliev 1829 - added (experimental) CoreAudio driver
104 persson 1888 - applied old fixes to the ASIO driver that were included in the
105     previous binary release but accidentally never committed to CVS
106     (fixes #117)
107 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
108     win64)
109 persson 1895 - VST: added support for sample rate and buffer size changes
110     - VST: close editor (Fantasia) when the VST is removed
111 persson 1908 - VST: avoid opening Fantasia more than once for each VST instance

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