* C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
  a pointer to the launched InstrumentEditor object

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