* added (experimental) CoreAudio driver

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