1 schoenebeck 1599 Version CVS HEAD (?)
2    
3 schoenebeck 1639 * packaging changes:
4     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
5     causing e.g. the libgig test to fail when
6     "./configure --disable-jack-driver" was used
7     (patch by Alexis Ballier)
8 persson 1713 - fixed compilation with gcc 4.3
9 persson 1792 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
10 persson 1794 - fixed configure so it detects x86_64 (#107)
11 persson 1808 - fixes for building with newer MinGW versions
12     - fix for building with bison 2.4 (#111)
13 schoenebeck 1639
14 schoenebeck 1601 * general changes:
15     - bugfix: on some POSIX systems instrument editor plugins refused to
16     load as we used a non-portable Linux specific struct field
17     (fixes bug #70, patch by Ronald Baljeu)
18 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
19     plugin DLL on Windows systems failed
20 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded
21     - optimized the SynchronizedConfig class so it doesn't wait
22     unnecessarily long after an update
23 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
24     events (e.g. to highlight the pressed keys on the virtual keyboard
25     of gigedit)
26 schoenebeck 1659 - added support for triggering notes by instrument editors (see above)
27 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
28 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation
29     is only used by very few systems, most pick the int math
30     implementation, which is usually faster)
31 persson 1748 - fixes for audio drivers with varying buffer sizes
32 persson 1777 - experimental support for running LinuxSampler as a DSSI, LV2 and
33     VST plugin
34 iliev 1789 - notification events for stream/voice count statistics are now sent
35     only when there are actual changes
36 persson 1790 - added memory ordering constraints to improve stability on
37     multi-core and multi-cpu systems
38 schoenebeck 1800 - maximum voices and disk streams can now be altered at runtime
39 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
40 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
41     be switched on by command line option "--stacktrace" (the automatic
42     stacktrace mechanism seems to be broken on most systems at the moment)
43 schoenebeck 1601
44 schoenebeck 1599 * audio driver:
45     - removed the nonsense audio channel constraint (which was hard coded to
46     max. 100 audio channels) for most audio drivers
47 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
48     opposed to the LSCP specs
49 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
50     reflected the wrong value
51 persson 1644 - fixed a memory management bug in ASIO driver
52 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used
53 persson 1777 - JACK: use jack_client_open instead of the deprecated
54 persson 1748 jack_client_new
55 iliev 1829 - added (experimental) CoreAudio driver
56 schoenebeck 1599
57 persson 1651 * MIDI driver:
58     - added JACK MIDI driver
59 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
60     want to (mis)use it for some purpose ("fixed" in all current MIDI
61     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
62 persson 1651
63 schoenebeck 1604 * instruments database:
64 iliev 1603 - avoid time consuming samples scanning when adding instruments
65     to the instruments database
66 iliev 1727 - added support for handling lost files in the instruments database
67 iliev 1781 - Implemented option for adding instruments in separate directories
68     in the instruments database
69     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
70 iliev 1603
71 persson 1644 * Gigasampler format engine:
72     - fixed a memory leak that could happen when a channel was deleted
73     while notes were playing
74 persson 1646 - made it possible to load an instrument even if the audio thread
75     isn't running
76 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
77     enough for piano gigs with pedal noise samples
78 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
79     respective FX send MIDI controller was used
80 schoenebeck 1724 - added support for GM global device volume SysEx message
81 schoenebeck 1762 (can be selected at compile time to either apply globally to the
82     whole sampler [default] or only to the sampler channels that are
83     connected to the respective MIDI input port the SysEx message arrived
84     on)
85 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
86     sometimes wrongly killed in the same buffer, causing no sound to
87     be played
88 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
89     which is usally used to switch a part between chromatic sounds and
90     drumkit sounds (as opposed to their common default setting of MIDI
91     part 10 being a drumkit part and all other ones chromatic parts), in
92     LS however one can switch between the first 16 MIDI instrument maps
93     defined for the sampler
94 persson 1764 - made it possible to create multiple sample channels even if the
95     audio thread isn't running
96 persson 1644
97 schoenebeck 1687 * LSCP server:
98     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
99     react on MIDI data arriving on certain sampler channels (so far only
100     Note-On and Note-Off events are sent via this LSCP event)
101 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
102     react on MIDI data arriving on certain MIDI input devices (so far only
103     Note-On and Note-Off events are sent via this LSCP event)
104 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
105     SET DB_INSTRUMENT FILE_PATH
106 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
107     frontends to send MIDI messages to specific sampler channel
108     - added two additional fields to GET FILE INSTRUMENT INFO command -
109     KEY_BINDINGS and KEYSWITCH_BINDINGS
110 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
111     was incorrect
112 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
113 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
114     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
115     be triggered respectively
116     - added new LSCP command "SET STREAMS" to globally alter the maximum
117     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
118     which will be triggered respectively
119 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
120     a gigedit file dialog is opened)
121 schoenebeck 1687
122 iliev 1761 * Bug fixes:
123     - fixed a crash which occurs when removing a sampler channel waiting
124     to start instrument loading after another channel
125 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
126     instrument loading in progress (bug #113)
127 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
128     instrument with PERSISTENT load mode
129 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
130     - fixed memory leaks when issuing the following LSCP commands:
131     GET AUDIO_OUTPUT_DRIVER INFO
132     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
133     GET MIDI_INPUT_DRIVER INFO
134     GET MIDI_INPUT_DRIVER_PARAMETER INFO
135     - fixed possible compilation error when sqlite is not present
136 iliev 1761
137    
138 schoenebeck 1560 Version 0.5.1 (6 December 2007)
139 schoenebeck 1454
140     * packaging changes:
141     - added autoconf checks for pthread library
142     - added autoconf check for pthread bug found on certain NPTL-enabled
143     glibc versions (see Gentoo bug report #194076)
144 senoner 1502 - added autoconf checks for MS Windows
145 schoenebeck 1454
146 persson 1455 * general changes:
147     - bugfix: the thread used by an editor plugin didn't die when the
148     editor closed
149 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
150     out all the space. operator--() did not apply size_mask after
151     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
152     order to avoid problems with the _NonVolatileReader functions.
153     - bugfix: Stream.h: added a missing divide by BytesPerSample in
154     GetWriteSpace(). Since this function is currently only used in
155     the stream's qsort() compare function, it didn't trigger any
156     bugs.
157     - Resampler.h, Synthesizer.h: cubic interpolation now works in
158     24bit mode too. Faster method to read 24bit words on little
159     endian machines (x86): replaced 3 byte reads + shifts with a 1
160     unaligned 32bit read and shift
161     - experimental support for MS Windows (MIDI input via MME, AUDIO
162     output via ASIO)
163     - made handling of SIGINT signal (Ctrl-C) a bit more robust
164 iliev 1541 - support for monitoring the total number of active disk streams
165     (new LSCP commands: GET TOTAL_STREAM_COUNT,
166     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
167 persson 1455
168 senoner 1500 * AUDIO driver:
169 persson 1534 - added Windows ASIO low latency audio driver
170 senoner 1500
171 senoner 1485 * MIDI driver:
172 schoenebeck 1495 - added MME Windows MIDI driver
173 senoner 1485
174 schoenebeck 1471 * LSCP server:
175     - added support for Windows style path / filenames, however with
176     forward slash path separators instead of backslash
177     (i.e. "C:/foo/bar.gig")
178 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
179     apostrophes as well
180 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
181     "LIST FILE INSTRUMENTS <file>" and
182     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
183     about an arbitrary instrument file on the system where the sampler is
184     running on
185 schoenebeck 1471
186 schoenebeck 1424 Version 0.5.0 (15 October 2007)
187 schoenebeck 947
188 schoenebeck 1065 * packaging changes:
189 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
190     API header files anymore
191 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
192     the Doxygen API documentation (explicitly listed in Doxyfile.in)
193 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
194     capable to execute our autoconf environment, thus no need anymore
195     to maintain the compile time configuration file (osx/version.h) for
196     OSX manually (patch by Toshi Nagata)
197 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
198     parameters
199 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
200     C++ API header files, all implementation internal global definitions
201     are now in global_private.h
202     - atomic.h is not exposed to the C++ API anymore
203     - no need to include config.h anymore for using LS's API header files
204     - fixed warnings in API doc generation
205 schoenebeck 1065
206 schoenebeck 947 * general changes:
207     - replaced the old, confusing MIDI program change mechanism by a
208     flexible MIDI instrument mapper which allows to map arbitrary
209 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
210 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
211     loaded on the respective channel when such MIDI program change
212     messages arrive, beside that, each entry allows to define a life-time
213     strategy for the instrument, so the user can define whether the
214     instrument should i.e. be permanently loaded (to be able to switch
215     quickly among sounds) or i.e. loaded just on demand when the
216     respective program change arrives (to safe RAM space), as well as a
217     global volume factor for each entry, so the user can adjust the volume
218     dynamic of his mapped instrument collection without having to modify
219 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
220     MIDI instrument maps and assign each sampler channel individually
221     a certain map, so that i.e. separation of normal instruments and
222     drumkits is possible
223 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
224     MIDI instrument maps, MIDI instruments, FX sends, global volume.
225 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
226     due to a constant size RingBuffer FIFO which is now replaced by a
227     dynamic (unlimited) size std::list FIFO
228 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
229     output channels for being processed by external effect processors
230     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
231     controllers
232 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
233 iliev 1130 - Implemented new, improved notification system
234 schoenebeck 1149 - fixed compilation errors regarding OSX
235     (patch by Toshi Nagata)
236 iliev 1161 - implemented instruments database
237 iliev 1345 - added support for escape sequences to the instruments database
238 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
239     within the sampler's process (by using instrument editor plugins),
240     you'll notice the new "Registered instrument editors:" message on
241 schoenebeck 1407 startup, added a new LSCP command:
242     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
243 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
244     given sampler channel, the plugin path can be overridden at compile
245     time with ./configure --enable-plugin-dir=/some/dir
246 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
247     in the sampler's process to safely edit instruments while playing
248     without a crash (hopefully) by either suspending single regions
249     wherever possible or if unavoidable whole engine(s)
250 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
251     policy and priority on thread level, set a minimum stack size for
252     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
253     threads simply inherited properties of starting thread instead of
254     setting their own policy and priority
255 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
256     main process did not wait for the stack trace process to finish
257     its output
258 persson 1248 - fixed some minor memory leaks
259 schoenebeck 1259 - reenabled assembly features support, at the moment only for
260     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
261 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
262     register, to avoid relocations in the text segment at runtime)
263 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
264 schoenebeck 947
265     * MIDI driver:
266     - dispatch bank select (MSB and LSB) messages
267    
268 schoenebeck 1049 * audio driver:
269     - the ALSA audio output driver parameters now reflect the correct
270     parameter value ranges for the respective selected sound card
271     (patch by Till Wimmer, a bit fixed and extended)
272    
273 persson 951 * Gigasampler format engine:
274     - if a filter is used and EG2 finishes before EG1, let the voice
275     die when EG2 has finished (this fixes a problem with clicks and
276     voice starvation for some gigs)
277 persson 1038 - playback is no longer disabled during instrument loading
278     - all notes playing on a channel that changes its instrument keep
279     playing with the old instrument until they get a note off
280     command
281 persson 1039 - EG fix: a release value of zero could cause noises or crash
282 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
283 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
284     above max sustain level, which means that there is a decay phase
285     even if sustain is 100%
286 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
287     noises or crashes
288 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
289 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
290     supplied to the configure script (fixes #46)
291 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
292     instead of a fix value
293 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
294     127 (solo mode) only kill voices if the respective mode really
295     changed
296 persson 951
297 schoenebeck 1244 * LSCP server:
298     - fixed compile time error for old Bison versions
299     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
300 schoenebeck 1245 - parser now supports extended ASCII character set
301     (up to ASCII code 255, i.e. includes now umlauts and accents)
302     - filename arguments in LSCP commands now allow to use escape
303     sequences, that is directly literal as one of: \', \", \\, \n, \r,
304     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
305     code value like \xf2) (fixes bug #24)
306 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
307     least one of their text-based parameters (i.e. name, description):
308     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
309     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
310     "SET DB_INSTRUMENT_DIRECTORY NAME",
311     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
312     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
313     "FIND DB_INSTRUMENT_DIRECTORIES"
314 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
315     occured, the unexpected character and the actually expected, possible
316     character(s), the latter only if less than 5 possibilities)
317 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
318     settings
319 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
320     of strings were treated as being one string containing commas
321     (fixes #57)
322 schoenebeck 1244
323 iliev 959 * Bug fixes:
324     - fixed crash occurring on certain LSCP scripts (Bug 39)
325 persson 1038 - another thread safety fix for lscp "load engine" and "set
326     channel audio output device"
327 iliev 1283 - fixed a crash which occurs when reassigning the same engine
328     on a sampler channel with connected MIDI device
329 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
330     device connected to a sampler channel to number less then or equal
331     to the index of the port to which the sampler channel is connected.
332 iliev 1296 - The previous bindings were not been disconnected when altering
333     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
334     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
335 iliev 1297 - The active stream/voice count statistic was incorrect.
336 iliev 1298 - notification events were not been sent for some sampler
337     channel changes
338 iliev 1305 - added default min and max values to restrict the number of allowed
339     audio output channels and MIDI input ports
340 iliev 1306 - the connection to the PCM interface is now closed when destroying
341     an audio output device
342 schoenebeck 1332 - files with slash in their path or filename could not be loaded
343 iliev 959
344 schoenebeck 1221 * test cases:
345     - updated and fixed (haven't been touched in a while)
346    
347 schoenebeck 937 Version 0.4.0 (24 November 2006)
348 persson 696
349 schoenebeck 697 * packaging changes:
350 capela 868 - changed deprecated copyright attribute to license; added ldconfig
351     to post-(un)install steps; added devel package for liblinuxsampler;
352     to linuxsampler.spec (RPM)
353 schoenebeck 697 - install necessary development header files for allowing 3rd party
354     applications to link against liblinuxsampler
355     - liblinuxsampler's API documentation can be generated with 'make docs'
356     (Doxygen required)
357 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
358     implementation (currently either an integer math solution or a
359     di-harmonic approximation), automatic detection can be overriden
360     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
361     configure script argument though (mandatory for cross-compilation)
362 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
363     provided some on his own (as CXXFLAGS)
364 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
365     messages
366 schoenebeck 852 - added compile time options to allow disabling the various audio and
367     MIDI drivers
368 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
369     (patch by Ebrahim Mayat)
370 schoenebeck 697
371 persson 696 * Gigasampler format engine:
372 schoenebeck 738 - extensive synthesis optimization
373     (reimplementation of EGs and LFO(s), removed synthesis parameter
374     prerendering and the synthesis parameter matrix in general, splitting
375     each audio fragment into subfragments now where each subfragment uses
376 persson 830 constant pitch and filter coefficients. The volume coefficient is
377     linearly interpolated inside a subfragment, unless
378     --disable-interpolate-volume is set.)
379 persson 696 - fine tuning of the EG modulation parameters
380 persson 729 - improved filter cutoff calculation by adding support for the
381     following gig parameters: Cutoff freq (used when no cutoff
382     controller is defined), Control invert, Minimum cutoff, Velocity
383 persson 791 curve and Velocity range. The keyboard tracking now scales
384     cutoff frequency instead of resonance.
385 persson 877 - added support for gig parameter Resonance.
386 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
387 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
388     which can be overridden with --enable-global-attenuation
389 persson 783 - EG fixes: made the length of "attack hold" stage more
390     accurate. Release stage can now start before attack stage
391 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
392     time now has a minimal value to prevent clicks.
393 persson 799 - fixed pitch changes larger than one octave
394 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
395     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
396     all modes can be altered via standard GM messages, that is CC5 for
397     altering portamento time, CC65 for enabling / disabling portamento
398     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
399 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
400     parameter) and crossfade
401 persson 831 - added support for the "attenuation controller threshold" gig
402     parameter
403 persson 832 - added smoothing of volume changes caused by control change
404     messages
405 persson 865 - sample loop parameters are now taken from the DimensionRegion
406     instead of the wave chunk
407     - fixed keyswitching for v3 gigs with a number of keyswitch splits
408     not equal to a power of two
409 persson 877 - reimplementation of the filter algorithm. The new filter is more
410     accurate and supports all gig filter types, including bandreject
411     and lowpass turbo.
412 persson 903 - real support for 24 bit samples - samples are not truncated to
413     16 bits anymore
414     - support for aftertouch (channel pressure, not polyphonic
415     aftertouch)
416 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
417     amplifying from 0)
418 persson 696
419 schoenebeck 711 * LSCP server:
420     - fixed application exit on broken pipe error (fixes bug #20)
421 iliev 793 - fixed the notification messages delay due to lack of
422     network activity (fixes bug #26)
423 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
424     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
425 schoenebeck 711
426 schoenebeck 838 * audio driver:
427     - added aRts audio output driver (by no means RT safe)
428    
429 schoenebeck 775 * MIDI driver:
430     - fixed legacy sysex code which caused dispatching of MIDI SysEx
431     messages several times instead of once
432 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
433     for events (i.e. for offline rendering based MIDI drivers)
434 persson 922 - added checks for bad MIDI data
435 schoenebeck 775
436 schoenebeck 900 * linuxsampler application:
437     - show available sampler engine types on startup
438    
439 schoenebeck 705 * general changes:
440     - support for muting sampler channels and solo mode of the same, two new
441     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
442     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
443     introduced for this, the behavior is the same like on a mixer console
444 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
445     --enable-process-muted-channels which can be used to enable the
446     processing of muted channels.
447 iliev 777 - support for sostenuto pedal
448 iliev 779 - support for monitoring the total number of active voices
449 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
450     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
451 persson 835 - fixed some memory management errors
452 persson 841 - fixed some concurrency problems that could lead to crashes when
453     LSCP commands were executed
454 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
455     sampler channel (fixes bug #36)
456 schoenebeck 705
457 schoenebeck 692 Version 0.3.3 (15 July 2005)
458 schoenebeck 686
459     * packaging changes:
460     - fixed compilation with gcc 4.0
461    
462 schoenebeck 687 * Gigasampler format engine:
463     - LFO preprocessing was performed even though the respective LFO was
464     disabled by the instrument patch (minor efficiency fix)
465 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
466     for volume ramp downs in the same fragment (needed for current voice
467     stealing implementation) then simply inform the user with a warning
468     about possible click sounds and reduce the volume ramp down
469     appropriately instead of cancelling the audio device connection
470 schoenebeck 687
471 schoenebeck 677 Version 0.3.2 (24 June 2005)
472 schoenebeck 609
473     * packaging changes:
474     - updated autotools build files to compile on OS X
475     (conditional compilation of CoreMIDI and MidiShare drivers)
476 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
477     './configure --disable-asm' (definitely not recommended)
478 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
479     - require automake (>= 1.5) for 'make -f Makefile.cvs'
480     (due to 'dist-bzip2' automake option)
481 schoenebeck 649
482     * Gigasampler format engine:
483     - support for the gig parameters for "release velocity response" curves
484     - fine tuning of the EGADSR envelope
485     - volume of release triggered samples now depends on note-on velocity,
486     note length and gig parameter "release trigger decay" instead of
487     note-off velocity.
488 schoenebeck 663 - revised voice stealing
489     (fixes crash and endless loop caused by voice stealing)
490 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
491 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
492     instead of when the respective voice is actually launched
493     (fixes undefined behavior if stolen voices belonged to a key group -
494     this case was followed by a "killed voice survived" error message)
495 schoenebeck 669 - fixed minor issue with null/silence samples
496     (those stole voices even though they don't need a voice at all which
497     resulted in "voice stealing didn't work out" messages)
498 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
499     instrument or audio output device change
500 schoenebeck 654
501 schoenebeck 620 * LSCP server:
502 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
503 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
504 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
505 schoenebeck 609
506 schoenebeck 668 * linuxsampler application:
507     - added command line parameters --lscp-addr and --lscp-port to override
508     default IP address and port of LSCP server
509    
510 schoenebeck 579 Version 0.3.1 (24 May 2005)
511    
512     * initial release
