* maximum voices and disk streams can now be altered at runtime (added new
  LSCP commands "GET VOICES", "SET VOICES", "GET STREAMS", "SET STREAMS"
  and accordingly new LSCP events "GLOBAL_INFO:VOICES" and
  "GLOBAL_INFO:STREAMS")
* bumped version to 0.5.1.8cvs

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