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 persson 1842 - fixed building with libgig installed in a non-standard directory
14 schoenebeck 1639
15 schoenebeck 1601 * general changes:
16     - bugfix: on some POSIX systems instrument editor plugins refused to
17     load as we used a non-portable Linux specific struct field
18     (fixes bug #70, patch by Ronald Baljeu)
19 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
20     plugin DLL on Windows systems failed
21 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded
22     - optimized the SynchronizedConfig class so it doesn't wait
23     unnecessarily long after an update
24 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
25     events (e.g. to highlight the pressed keys on the virtual keyboard
26     of gigedit)
27 schoenebeck 1659 - added support for triggering notes by instrument editors (see above)
28 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
29 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation
30     is only used by very few systems, most pick the int math
31     implementation, which is usually faster)
32 persson 1748 - fixes for audio drivers with varying buffer sizes
33 persson 1777 - experimental support for running LinuxSampler as a DSSI, LV2 and
34     VST plugin
35 iliev 1789 - notification events for stream/voice count statistics are now sent
36     only when there are actual changes
37 persson 1790 - added memory ordering constraints to improve stability on
38     multi-core and multi-cpu systems
39 schoenebeck 1800 - maximum voices and disk streams can now be altered at runtime
40 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
41 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
42     be switched on by command line option "--stacktrace" (the automatic
43     stacktrace mechanism seems to be broken on most systems at the moment)
44 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
45     a pointer to the launched InstrumentEditor object
46 schoenebeck 1876 - added optional 3rd party user data parameter for following
47     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
48     InstrumentEditor::Launch(),
49     InstrumentManager::LaunchInstrumentEditor()
50 schoenebeck 1601
51 schoenebeck 1599 * audio driver:
52     - removed the nonsense audio channel constraint (which was hard coded to
53     max. 100 audio channels) for most audio drivers
54 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
55     opposed to the LSCP specs
56 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
57     reflected the wrong value
58 persson 1644 - fixed a memory management bug in ASIO driver
59 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used
60 persson 1777 - JACK: use jack_client_open instead of the deprecated
61 persson 1748 jack_client_new
62 iliev 1829 - added (experimental) CoreAudio driver
63 schoenebeck 1599
64 persson 1651 * MIDI driver:
65     - added JACK MIDI driver
66 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
67     want to (mis)use it for some purpose ("fixed" in all current MIDI
68     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
69 persson 1651
70 schoenebeck 1604 * instruments database:
71 iliev 1603 - avoid time consuming samples scanning when adding instruments
72     to the instruments database
73 iliev 1727 - added support for handling lost files in the instruments database
74 iliev 1781 - Implemented option for adding instruments in separate directories
75     in the instruments database
76     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
77 iliev 1603
78 persson 1644 * Gigasampler format engine:
79     - fixed a memory leak that could happen when a channel was deleted
80     while notes were playing
81 persson 1646 - made it possible to load an instrument even if the audio thread
82     isn't running
83 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
84     enough for piano gigs with pedal noise samples
85 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
86     respective FX send MIDI controller was used
87 schoenebeck 1724 - added support for GM global device volume SysEx message
88 schoenebeck 1762 (can be selected at compile time to either apply globally to the
89     whole sampler [default] or only to the sampler channels that are
90     connected to the respective MIDI input port the SysEx message arrived
91     on)
92 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
93     sometimes wrongly killed in the same buffer, causing no sound to
94     be played
95 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
96     which is usally used to switch a part between chromatic sounds and
97     drumkit sounds (as opposed to their common default setting of MIDI
98     part 10 being a drumkit part and all other ones chromatic parts), in
99     LS however one can switch between the first 16 MIDI instrument maps
100     defined for the sampler
101 persson 1764 - made it possible to create multiple sample channels even if the
102     audio thread isn't running
103 persson 1844 - fixed crash when removing channel with active voices (#116)
104 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
105     un-cache the respective sample if it's really not used by any
106     sampler engine anymore
107     - re-cache samples in case they were changed by an instrument editor,
108     e.g. when a sample was added while playing (#82)
109 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
110     same time stamp as the voice's note-on event and occured both in the
111     same audio fragment cycle (fixes bug #112)
112 persson 1858 - added support for the "fine tune" and "pitch bend range"
113     instrument-level gig parameters
114     - fixed minor artifacts in pitch bend handling
115 schoenebeck 1860 - added support for GS Reset SysEx message
116 persson 1862 - allow gig files to use unlimited downward pitch shifting
117     - added a limit check for upward pitch shifting
118 persson 1644
119 schoenebeck 1687 * LSCP server:
120     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
121     react on MIDI data arriving on certain sampler channels (so far only
122     Note-On and Note-Off events are sent via this LSCP event)
123 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
124     react on MIDI data arriving on certain MIDI input devices (so far only
125     Note-On and Note-Off events are sent via this LSCP event)
126 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
127     SET DB_INSTRUMENT FILE_PATH
128 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
129     frontends to send MIDI messages to specific sampler channel
130     - added two additional fields to GET FILE INSTRUMENT INFO command -
131     KEY_BINDINGS and KEYSWITCH_BINDINGS
132 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
133     was incorrect
134 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
135 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
136     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
137     be triggered respectively
138     - added new LSCP command "SET STREAMS" to globally alter the maximum
139     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
140     which will be triggered respectively
141 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
142     a gigedit file dialog is opened)
143 iliev 1848 - close all connections when LSCPServer is deleted
144 schoenebeck 1687
145 iliev 1761 * Bug fixes:
146     - fixed a crash which occurs when removing a sampler channel waiting
147     to start instrument loading after another channel
148 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
149     instrument loading in progress (bug #113)
150 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
151     instrument with PERSISTENT load mode
152 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
153     - fixed memory leaks when issuing the following LSCP commands:
154     GET AUDIO_OUTPUT_DRIVER INFO
155     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
156     GET MIDI_INPUT_DRIVER INFO
157     GET MIDI_INPUT_DRIVER_PARAMETER INFO
158     - fixed possible compilation error when sqlite is not present
159 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
160 iliev 1847 - fixed crash when changing the audio output device of a sampler
161     channel with loaded instrument and start playing notes
162 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
163 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
164     PowerPC, which probably could cause crashes on that platform
165 iliev 1761
166    
167 schoenebeck 1560 Version 0.5.1 (6 December 2007)
168 schoenebeck 1454
169     * packaging changes:
170     - added autoconf checks for pthread library
171     - added autoconf check for pthread bug found on certain NPTL-enabled
172     glibc versions (see Gentoo bug report #194076)
173 senoner 1502 - added autoconf checks for MS Windows
174 schoenebeck 1454
175 persson 1455 * general changes:
176     - bugfix: the thread used by an editor plugin didn't die when the
177     editor closed
178 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
179     out all the space. operator--() did not apply size_mask after
180     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
181     order to avoid problems with the _NonVolatileReader functions.
182     - bugfix: Stream.h: added a missing divide by BytesPerSample in
183     GetWriteSpace(). Since this function is currently only used in
184     the stream's qsort() compare function, it didn't trigger any
185     bugs.
186     - Resampler.h, Synthesizer.h: cubic interpolation now works in
187     24bit mode too. Faster method to read 24bit words on little
188     endian machines (x86): replaced 3 byte reads + shifts with a 1
189     unaligned 32bit read and shift
190     - experimental support for MS Windows (MIDI input via MME, AUDIO
191     output via ASIO)
192     - made handling of SIGINT signal (Ctrl-C) a bit more robust
193 iliev 1541 - support for monitoring the total number of active disk streams
194     (new LSCP commands: GET TOTAL_STREAM_COUNT,
195     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
196 persson 1455
197 senoner 1500 * AUDIO driver:
198 persson 1534 - added Windows ASIO low latency audio driver
199 senoner 1500
200 senoner 1485 * MIDI driver:
201 schoenebeck 1495 - added MME Windows MIDI driver
202 senoner 1485
203 schoenebeck 1471 * LSCP server:
204     - added support for Windows style path / filenames, however with
205     forward slash path separators instead of backslash
206     (i.e. "C:/foo/bar.gig")
207 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
208     apostrophes as well
209 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
210     "LIST FILE INSTRUMENTS <file>" and
211     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
212     about an arbitrary instrument file on the system where the sampler is
213     running on
214 schoenebeck 1471
215 schoenebeck 1424 Version 0.5.0 (15 October 2007)
216 schoenebeck 947
217 schoenebeck 1065 * packaging changes:
218 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
219     API header files anymore
220 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
221     the Doxygen API documentation (explicitly listed in Doxyfile.in)
222 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
223     capable to execute our autoconf environment, thus no need anymore
224     to maintain the compile time configuration file (osx/version.h) for
225     OSX manually (patch by Toshi Nagata)
226 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
227     parameters
228 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
229     C++ API header files, all implementation internal global definitions
230     are now in global_private.h
231     - atomic.h is not exposed to the C++ API anymore
232     - no need to include config.h anymore for using LS's API header files
233     - fixed warnings in API doc generation
234 schoenebeck 1065
235 schoenebeck 947 * general changes:
236     - replaced the old, confusing MIDI program change mechanism by a
237     flexible MIDI instrument mapper which allows to map arbitrary
238 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
239 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
240     loaded on the respective channel when such MIDI program change
241     messages arrive, beside that, each entry allows to define a life-time
242     strategy for the instrument, so the user can define whether the
243     instrument should i.e. be permanently loaded (to be able to switch
244     quickly among sounds) or i.e. loaded just on demand when the
245     respective program change arrives (to safe RAM space), as well as a
246     global volume factor for each entry, so the user can adjust the volume
247     dynamic of his mapped instrument collection without having to modify
248 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
249     MIDI instrument maps and assign each sampler channel individually
250     a certain map, so that i.e. separation of normal instruments and
251     drumkits is possible
252 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
253     MIDI instrument maps, MIDI instruments, FX sends, global volume.
254 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
255     due to a constant size RingBuffer FIFO which is now replaced by a
256     dynamic (unlimited) size std::list FIFO
257 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
258     output channels for being processed by external effect processors
259     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
260     controllers
261 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
262 iliev 1130 - Implemented new, improved notification system
263 schoenebeck 1149 - fixed compilation errors regarding OSX
264     (patch by Toshi Nagata)
265 iliev 1161 - implemented instruments database
266 iliev 1345 - added support for escape sequences to the instruments database
267 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
268     within the sampler's process (by using instrument editor plugins),
269     you'll notice the new "Registered instrument editors:" message on
270 schoenebeck 1407 startup, added a new LSCP command:
271     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
272 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
273     given sampler channel, the plugin path can be overridden at compile
274     time with ./configure --enable-plugin-dir=/some/dir
275 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
276     in the sampler's process to safely edit instruments while playing
277     without a crash (hopefully) by either suspending single regions
278     wherever possible or if unavoidable whole engine(s)
279 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
280     policy and priority on thread level, set a minimum stack size for
281     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
282     threads simply inherited properties of starting thread instead of
283     setting their own policy and priority
284 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
285     main process did not wait for the stack trace process to finish
286     its output
287 persson 1248 - fixed some minor memory leaks
288 schoenebeck 1259 - reenabled assembly features support, at the moment only for
289     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
290 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
291     register, to avoid relocations in the text segment at runtime)
292 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
293 schoenebeck 947
294     * MIDI driver:
295     - dispatch bank select (MSB and LSB) messages
296    
297 schoenebeck 1049 * audio driver:
298     - the ALSA audio output driver parameters now reflect the correct
299     parameter value ranges for the respective selected sound card
300     (patch by Till Wimmer, a bit fixed and extended)
301    
302 persson 951 * Gigasampler format engine:
303     - if a filter is used and EG2 finishes before EG1, let the voice
304     die when EG2 has finished (this fixes a problem with clicks and
305     voice starvation for some gigs)
306 persson 1038 - playback is no longer disabled during instrument loading
307     - all notes playing on a channel that changes its instrument keep
308     playing with the old instrument until they get a note off
309     command
310 persson 1039 - EG fix: a release value of zero could cause noises or crash
311 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
312 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
313     above max sustain level, which means that there is a decay phase
314     even if sustain is 100%
315 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
316     noises or crashes
317 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
318 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
319     supplied to the configure script (fixes #46)
320 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
321     instead of a fix value
322 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
323     127 (solo mode) only kill voices if the respective mode really
324     changed
325 persson 951
326 schoenebeck 1244 * LSCP server:
327     - fixed compile time error for old Bison versions
328     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
329 schoenebeck 1245 - parser now supports extended ASCII character set
330     (up to ASCII code 255, i.e. includes now umlauts and accents)
331     - filename arguments in LSCP commands now allow to use escape
332     sequences, that is directly literal as one of: \', \", \\, \n, \r,
333     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
334     code value like \xf2) (fixes bug #24)
335 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
336     least one of their text-based parameters (i.e. name, description):
337     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
338     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
339     "SET DB_INSTRUMENT_DIRECTORY NAME",
340     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
341     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
342     "FIND DB_INSTRUMENT_DIRECTORIES"
343 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
344     occured, the unexpected character and the actually expected, possible
345     character(s), the latter only if less than 5 possibilities)
346 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
347     settings
348 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
349     of strings were treated as being one string containing commas
350     (fixes #57)
351 schoenebeck 1244
352 iliev 959 * Bug fixes:
353     - fixed crash occurring on certain LSCP scripts (Bug 39)
354 persson 1038 - another thread safety fix for lscp "load engine" and "set
355     channel audio output device"
356 iliev 1283 - fixed a crash which occurs when reassigning the same engine
357     on a sampler channel with connected MIDI device
358 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
359     device connected to a sampler channel to number less then or equal
360     to the index of the port to which the sampler channel is connected.
361 iliev 1296 - The previous bindings were not been disconnected when altering
362     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
363     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
364 iliev 1297 - The active stream/voice count statistic was incorrect.
365 iliev 1298 - notification events were not been sent for some sampler
366     channel changes
367 iliev 1305 - added default min and max values to restrict the number of allowed
368     audio output channels and MIDI input ports
369 iliev 1306 - the connection to the PCM interface is now closed when destroying
370     an audio output device
371 schoenebeck 1332 - files with slash in their path or filename could not be loaded
372 iliev 959
373 schoenebeck 1221 * test cases:
374     - updated and fixed (haven't been touched in a while)
375    
376 schoenebeck 937 Version 0.4.0 (24 November 2006)
377 persson 696
378 schoenebeck 697 * packaging changes:
379 capela 868 - changed deprecated copyright attribute to license; added ldconfig
380     to post-(un)install steps; added devel package for liblinuxsampler;
381     to linuxsampler.spec (RPM)
382 schoenebeck 697 - install necessary development header files for allowing 3rd party
383     applications to link against liblinuxsampler
384     - liblinuxsampler's API documentation can be generated with 'make docs'
385     (Doxygen required)
386 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
387     implementation (currently either an integer math solution or a
388     di-harmonic approximation), automatic detection can be overriden
389     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
390     configure script argument though (mandatory for cross-compilation)
391 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
392     provided some on his own (as CXXFLAGS)
393 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
394     messages
395 schoenebeck 852 - added compile time options to allow disabling the various audio and
396     MIDI drivers
397 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
398     (patch by Ebrahim Mayat)
399 schoenebeck 697
400 persson 696 * Gigasampler format engine:
401 schoenebeck 738 - extensive synthesis optimization
402     (reimplementation of EGs and LFO(s), removed synthesis parameter
403     prerendering and the synthesis parameter matrix in general, splitting
404     each audio fragment into subfragments now where each subfragment uses
405 persson 830 constant pitch and filter coefficients. The volume coefficient is
406     linearly interpolated inside a subfragment, unless
407     --disable-interpolate-volume is set.)
408 persson 696 - fine tuning of the EG modulation parameters
409 persson 729 - improved filter cutoff calculation by adding support for the
410     following gig parameters: Cutoff freq (used when no cutoff
411     controller is defined), Control invert, Minimum cutoff, Velocity
412 persson 791 curve and Velocity range. The keyboard tracking now scales
413     cutoff frequency instead of resonance.
414 persson 877 - added support for gig parameter Resonance.
415 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
416 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
417     which can be overridden with --enable-global-attenuation
418 persson 783 - EG fixes: made the length of "attack hold" stage more
419     accurate. Release stage can now start before attack stage
420 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
421     time now has a minimal value to prevent clicks.
422 persson 799 - fixed pitch changes larger than one octave
423 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
424     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
425     all modes can be altered via standard GM messages, that is CC5 for
426     altering portamento time, CC65 for enabling / disabling portamento
427     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
428 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
429     parameter) and crossfade
430 persson 831 - added support for the "attenuation controller threshold" gig
431     parameter
432 persson 832 - added smoothing of volume changes caused by control change
433     messages
434 persson 865 - sample loop parameters are now taken from the DimensionRegion
435     instead of the wave chunk
436     - fixed keyswitching for v3 gigs with a number of keyswitch splits
437     not equal to a power of two
438 persson 877 - reimplementation of the filter algorithm. The new filter is more
439     accurate and supports all gig filter types, including bandreject
440     and lowpass turbo.
441 persson 903 - real support for 24 bit samples - samples are not truncated to
442     16 bits anymore
443     - support for aftertouch (channel pressure, not polyphonic
444     aftertouch)
445 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
446     amplifying from 0)
447 persson 696
448 schoenebeck 711 * LSCP server:
449     - fixed application exit on broken pipe error (fixes bug #20)
450 iliev 793 - fixed the notification messages delay due to lack of
451     network activity (fixes bug #26)
452 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
453     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
454 schoenebeck 711
455 schoenebeck 838 * audio driver:
456     - added aRts audio output driver (by no means RT safe)
457    
458 schoenebeck 775 * MIDI driver:
459     - fixed legacy sysex code which caused dispatching of MIDI SysEx
460     messages several times instead of once
461 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
462     for events (i.e. for offline rendering based MIDI drivers)
463 persson 922 - added checks for bad MIDI data
464 schoenebeck 775
465 schoenebeck 900 * linuxsampler application:
466     - show available sampler engine types on startup
467    
468 schoenebeck 705 * general changes:
469     - support for muting sampler channels and solo mode of the same, two new
470     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
471     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
472     introduced for this, the behavior is the same like on a mixer console
473 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
474     --enable-process-muted-channels which can be used to enable the
475     processing of muted channels.
476 iliev 777 - support for sostenuto pedal
477 iliev 779 - support for monitoring the total number of active voices
478 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
479     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
480 persson 835 - fixed some memory management errors
481 persson 841 - fixed some concurrency problems that could lead to crashes when
482     LSCP commands were executed
483 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
484     sampler channel (fixes bug #36)
485 schoenebeck 705
486 schoenebeck 692 Version 0.3.3 (15 July 2005)
487 schoenebeck 686
488     * packaging changes:
489     - fixed compilation with gcc 4.0
490    
491 schoenebeck 687 * Gigasampler format engine:
492     - LFO preprocessing was performed even though the respective LFO was
493     disabled by the instrument patch (minor efficiency fix)
494 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
495     for volume ramp downs in the same fragment (needed for current voice
496     stealing implementation) then simply inform the user with a warning
497     about possible click sounds and reduce the volume ramp down
498     appropriately instead of cancelling the audio device connection
499 schoenebeck 687
500 schoenebeck 677 Version 0.3.2 (24 June 2005)
501 schoenebeck 609
502     * packaging changes:
503     - updated autotools build files to compile on OS X
504     (conditional compilation of CoreMIDI and MidiShare drivers)
505 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
506     './configure --disable-asm' (definitely not recommended)
507 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
508     - require automake (>= 1.5) for 'make -f Makefile.cvs'
509     (due to 'dist-bzip2' automake option)
510 schoenebeck 649
511     * Gigasampler format engine:
512     - support for the gig parameters for "release velocity response" curves
513     - fine tuning of the EGADSR envelope
514     - volume of release triggered samples now depends on note-on velocity,
515     note length and gig parameter "release trigger decay" instead of
516     note-off velocity.
517 schoenebeck 663 - revised voice stealing
518     (fixes crash and endless loop caused by voice stealing)
519 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
520 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
521     instead of when the respective voice is actually launched
522     (fixes undefined behavior if stolen voices belonged to a key group -
523     this case was followed by a "killed voice survived" error message)
524 schoenebeck 669 - fixed minor issue with null/silence samples
525     (those stole voices even though they don't need a voice at all which
526     resulted in "voice stealing didn't work out" messages)
527 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
528     instrument or audio output device change
529 schoenebeck 654
530 schoenebeck 620 * LSCP server:
531 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
532 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
533 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
534 schoenebeck 609
535 schoenebeck 668 * linuxsampler application:
536     - added command line parameters --lscp-addr and --lscp-port to override
537     default IP address and port of LSCP server
538    
539 schoenebeck 579 Version 0.3.1 (24 May 2005)
540    
541     * initial release
