* bugfix: low-level lsatomic.h load function was broken on 64-bit
  PowerPC, which probably could cause crashes on that platform
* minor cleanups and optimization in lsatomic.h

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