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

32 schoenebeck 1639
33 schoenebeck 1601 * general changes:
34     - bugfix: on some POSIX systems instrument editor plugins refused to
35     load as we used a non-portable Linux specific struct field
36     (fixes bug #70, patch by Ronald Baljeu)
37 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
38     plugin DLL on Windows systems failed
39 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded
40     - optimized the SynchronizedConfig class so it doesn't wait
41     unnecessarily long after an update
42 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
43     events (e.g. to highlight the pressed keys on the virtual keyboard
44     of gigedit)
45 schoenebeck 1659 - added support for triggering notes by instrument editors (see above)
46 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
47 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation
48     is only used by very few systems, most pick the int math
49     implementation, which is usually faster)

58 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
59 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
60     be switched on by command line option "--stacktrace" (the automatic
61     stacktrace mechanism seems to be broken on most systems at the moment)
62 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
63     a pointer to the launched InstrumentEditor object
64 schoenebeck 1876 - added optional 3rd party user data parameter for following
65     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
66     InstrumentEditor::Launch(),
67     InstrumentManager::LaunchInstrumentEditor()
68 persson 1887 - theoretical fix: made SynchronizedConfig follow C++0x memory
69     model more strictly
70 persson 1895 - fixes for using large audio device buffers
71 persson 1951 - Windows: add the installation directory to the DLL search path

73     gigedit on systems with other GTK versions installed)
74 schoenebeck 1601
75 schoenebeck 1599 * audio driver:
76     - removed the nonsense audio channel constraint (which was hard coded to
77     max. 100 audio channels) for most audio drivers
78 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
79     opposed to the LSCP specs
80 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
81     reflected the wrong value
82 persson 1644 - fixed a memory management bug in ASIO driver
83 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used

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

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