* automatic stacktrace mechanism is now turned off by default and can
  be switched on by command line option "--stacktrace" (the automatic
  stacktrace mechanism seems to be broken on most systems at the moment)
* bumped version to 0.5.1.9cvs

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