* bugfix: pitch bend wasn't working with JackMidi, VST, LV2, Mme,
  CoreMidi or AU
* theoretical fix: made SynchronizedConfig follow C++0x memory model
  more strictly

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 persson 1887 - theoretical fix: made SynchronizedConfig follow C++0x memory
51     model more strictly
52 schoenebeck 1601
53 schoenebeck 1599 * audio driver:
54     - removed the nonsense audio channel constraint (which was hard coded to
55     max. 100 audio channels) for most audio drivers
56 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
57     opposed to the LSCP specs
58 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
59     reflected the wrong value
60 persson 1644 - fixed a memory management bug in ASIO driver
61 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used
62 persson 1777 - JACK: use jack_client_open instead of the deprecated
63 persson 1748 jack_client_new
64 iliev 1829 - added (experimental) CoreAudio driver
65 schoenebeck 1599
66 persson 1651 * MIDI driver:
67     - added JACK MIDI driver
68 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
69     want to (mis)use it for some purpose ("fixed" in all current MIDI
70     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
71 persson 1887 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, Mme,
72     CoreMidi or AU
73 persson 1651
74 schoenebeck 1604 * instruments database:
75 iliev 1603 - avoid time consuming samples scanning when adding instruments
76     to the instruments database
77 iliev 1727 - added support for handling lost files in the instruments database
78 iliev 1781 - Implemented option for adding instruments in separate directories
79     in the instruments database
80     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
81 iliev 1603
82 persson 1644 * Gigasampler format engine:
83     - fixed a memory leak that could happen when a channel was deleted
84     while notes were playing
85 persson 1646 - made it possible to load an instrument even if the audio thread
86     isn't running
87 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
88     enough for piano gigs with pedal noise samples
89 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
90     respective FX send MIDI controller was used
91 schoenebeck 1724 - added support for GM global device volume SysEx message
92 schoenebeck 1762 (can be selected at compile time to either apply globally to the
93     whole sampler [default] or only to the sampler channels that are
94     connected to the respective MIDI input port the SysEx message arrived
95     on)
96 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
97     sometimes wrongly killed in the same buffer, causing no sound to
98     be played
99 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
100     which is usally used to switch a part between chromatic sounds and
101     drumkit sounds (as opposed to their common default setting of MIDI
102     part 10 being a drumkit part and all other ones chromatic parts), in
103     LS however one can switch between the first 16 MIDI instrument maps
104     defined for the sampler
105 persson 1764 - made it possible to create multiple sample channels even if the
106     audio thread isn't running
107 persson 1844 - fixed crash when removing channel with active voices (#116)
108 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
109     un-cache the respective sample if it's really not used by any
110     sampler engine anymore
111     - re-cache samples in case they were changed by an instrument editor,
112     e.g. when a sample was added while playing (#82)
113 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
114     same time stamp as the voice's note-on event and occured both in the
115     same audio fragment cycle (fixes bug #112)
116 persson 1858 - added support for the "fine tune" and "pitch bend range"
117     instrument-level gig parameters
118     - fixed minor artifacts in pitch bend handling
119 schoenebeck 1860 - added support for GS Reset SysEx message
120 persson 1862 - allow gig files to use unlimited downward pitch shifting
121     - added a limit check for upward pitch shifting
122 persson 1644
123 schoenebeck 1687 * LSCP server:
124     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
125     react on MIDI data arriving on certain sampler channels (so far only
126     Note-On and Note-Off events are sent via this LSCP event)
127 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
128     react on MIDI data arriving on certain MIDI input devices (so far only
129     Note-On and Note-Off events are sent via this LSCP event)
130 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
131     SET DB_INSTRUMENT FILE_PATH
132 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
133     frontends to send MIDI messages to specific sampler channel
134     - added two additional fields to GET FILE INSTRUMENT INFO command -
135     KEY_BINDINGS and KEYSWITCH_BINDINGS
136 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
137     was incorrect
138 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
139 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
140     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
141     be triggered respectively
142     - added new LSCP command "SET STREAMS" to globally alter the maximum
143     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
144     which will be triggered respectively
145 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
146     a gigedit file dialog is opened)
147 iliev 1848 - close all connections when LSCPServer is deleted
148 iliev 1882 - hard close of all sockets on exit
149 schoenebeck 1687
150 iliev 1761 * Bug fixes:
151     - fixed a crash which occurs when removing a sampler channel waiting
152     to start instrument loading after another channel
153 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
154     instrument loading in progress (bug #113)
155 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
156     instrument with PERSISTENT load mode
157 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
158     - fixed memory leaks when issuing the following LSCP commands:
159     GET AUDIO_OUTPUT_DRIVER INFO
160     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
161     GET MIDI_INPUT_DRIVER INFO
162     GET MIDI_INPUT_DRIVER_PARAMETER INFO
163     - fixed possible compilation error when sqlite is not present
164 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
165 iliev 1847 - fixed crash when changing the audio output device of a sampler
166     channel with loaded instrument and start playing notes
167 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
168 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
169     PowerPC, which probably could cause crashes on that platform
170 iliev 1761
171    
172 schoenebeck 1560 Version 0.5.1 (6 December 2007)
173 schoenebeck 1454
174     * packaging changes:
175     - added autoconf checks for pthread library
176     - added autoconf check for pthread bug found on certain NPTL-enabled
177     glibc versions (see Gentoo bug report #194076)
178 senoner 1502 - added autoconf checks for MS Windows
179 schoenebeck 1454
180 persson 1455 * general changes:
181     - bugfix: the thread used by an editor plugin didn't die when the
182     editor closed
183 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
184     out all the space. operator--() did not apply size_mask after
185     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
186     order to avoid problems with the _NonVolatileReader functions.
187     - bugfix: Stream.h: added a missing divide by BytesPerSample in
188     GetWriteSpace(). Since this function is currently only used in
189     the stream's qsort() compare function, it didn't trigger any
190     bugs.
191     - Resampler.h, Synthesizer.h: cubic interpolation now works in
192     24bit mode too. Faster method to read 24bit words on little
193     endian machines (x86): replaced 3 byte reads + shifts with a 1
194     unaligned 32bit read and shift
195     - experimental support for MS Windows (MIDI input via MME, AUDIO
196     output via ASIO)
197     - made handling of SIGINT signal (Ctrl-C) a bit more robust
198 iliev 1541 - support for monitoring the total number of active disk streams
199     (new LSCP commands: GET TOTAL_STREAM_COUNT,
200     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
201 persson 1455
202 senoner 1500 * AUDIO driver:
203 persson 1534 - added Windows ASIO low latency audio driver
204 senoner 1500
205 senoner 1485 * MIDI driver:
206 schoenebeck 1495 - added MME Windows MIDI driver
207 senoner 1485
208 schoenebeck 1471 * LSCP server:
209     - added support for Windows style path / filenames, however with
210     forward slash path separators instead of backslash
211     (i.e. "C:/foo/bar.gig")
212 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
213     apostrophes as well
214 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
215     "LIST FILE INSTRUMENTS <file>" and
216     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
217     about an arbitrary instrument file on the system where the sampler is
218     running on
219 schoenebeck 1471
220 schoenebeck 1424 Version 0.5.0 (15 October 2007)
221 schoenebeck 947
222 schoenebeck 1065 * packaging changes:
223 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
224     API header files anymore
225 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
226     the Doxygen API documentation (explicitly listed in Doxyfile.in)
227 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
228     capable to execute our autoconf environment, thus no need anymore
229     to maintain the compile time configuration file (osx/version.h) for
230     OSX manually (patch by Toshi Nagata)
231 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
232     parameters
233 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
234     C++ API header files, all implementation internal global definitions
235     are now in global_private.h
236     - atomic.h is not exposed to the C++ API anymore
237     - no need to include config.h anymore for using LS's API header files
238     - fixed warnings in API doc generation
239 schoenebeck 1065
240 schoenebeck 947 * general changes:
241     - replaced the old, confusing MIDI program change mechanism by a
242     flexible MIDI instrument mapper which allows to map arbitrary
243 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
244 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
245     loaded on the respective channel when such MIDI program change
246     messages arrive, beside that, each entry allows to define a life-time
247     strategy for the instrument, so the user can define whether the
248     instrument should i.e. be permanently loaded (to be able to switch
249     quickly among sounds) or i.e. loaded just on demand when the
250     respective program change arrives (to safe RAM space), as well as a
251     global volume factor for each entry, so the user can adjust the volume
252     dynamic of his mapped instrument collection without having to modify
253 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
254     MIDI instrument maps and assign each sampler channel individually
255     a certain map, so that i.e. separation of normal instruments and
256     drumkits is possible
257 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
258     MIDI instrument maps, MIDI instruments, FX sends, global volume.
259 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
260     due to a constant size RingBuffer FIFO which is now replaced by a
261     dynamic (unlimited) size std::list FIFO
262 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
263     output channels for being processed by external effect processors
264     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
265     controllers
266 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
267 iliev 1130 - Implemented new, improved notification system
268 schoenebeck 1149 - fixed compilation errors regarding OSX
269     (patch by Toshi Nagata)
270 iliev 1161 - implemented instruments database
271 iliev 1345 - added support for escape sequences to the instruments database
272 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
273     within the sampler's process (by using instrument editor plugins),
274     you'll notice the new "Registered instrument editors:" message on
275 schoenebeck 1407 startup, added a new LSCP command:
276     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
277 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
278     given sampler channel, the plugin path can be overridden at compile
279     time with ./configure --enable-plugin-dir=/some/dir
280 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
281     in the sampler's process to safely edit instruments while playing
282     without a crash (hopefully) by either suspending single regions
283     wherever possible or if unavoidable whole engine(s)
284 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
285     policy and priority on thread level, set a minimum stack size for
286     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
287     threads simply inherited properties of starting thread instead of
288     setting their own policy and priority
289 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
290     main process did not wait for the stack trace process to finish
291     its output
292 persson 1248 - fixed some minor memory leaks
293 schoenebeck 1259 - reenabled assembly features support, at the moment only for
294     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
295 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
296     register, to avoid relocations in the text segment at runtime)
297 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
298 schoenebeck 947
299     * MIDI driver:
300     - dispatch bank select (MSB and LSB) messages
301    
302 schoenebeck 1049 * audio driver:
303     - the ALSA audio output driver parameters now reflect the correct
304     parameter value ranges for the respective selected sound card
305     (patch by Till Wimmer, a bit fixed and extended)
306    
307 persson 951 * Gigasampler format engine:
308     - if a filter is used and EG2 finishes before EG1, let the voice
309     die when EG2 has finished (this fixes a problem with clicks and
310     voice starvation for some gigs)
311 persson 1038 - playback is no longer disabled during instrument loading
312     - all notes playing on a channel that changes its instrument keep
313     playing with the old instrument until they get a note off
314     command
315 persson 1039 - EG fix: a release value of zero could cause noises or crash
316 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
317 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
318     above max sustain level, which means that there is a decay phase
319     even if sustain is 100%
320 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
321     noises or crashes
322 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
323 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
324     supplied to the configure script (fixes #46)
325 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
326     instead of a fix value
327 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
328     127 (solo mode) only kill voices if the respective mode really
329     changed
330 persson 951
331 schoenebeck 1244 * LSCP server:
332     - fixed compile time error for old Bison versions
333     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
334 schoenebeck 1245 - parser now supports extended ASCII character set
335     (up to ASCII code 255, i.e. includes now umlauts and accents)
336     - filename arguments in LSCP commands now allow to use escape
337     sequences, that is directly literal as one of: \', \", \\, \n, \r,
338     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
339     code value like \xf2) (fixes bug #24)
340 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
341     least one of their text-based parameters (i.e. name, description):
342     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
343     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
344     "SET DB_INSTRUMENT_DIRECTORY NAME",
345     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
346     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
347     "FIND DB_INSTRUMENT_DIRECTORIES"
348 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
349     occured, the unexpected character and the actually expected, possible
350     character(s), the latter only if less than 5 possibilities)
351 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
352     settings
353 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
354     of strings were treated as being one string containing commas
355     (fixes #57)
356 schoenebeck 1244
357 iliev 959 * Bug fixes:
358     - fixed crash occurring on certain LSCP scripts (Bug 39)
359 persson 1038 - another thread safety fix for lscp "load engine" and "set
360     channel audio output device"
361 iliev 1283 - fixed a crash which occurs when reassigning the same engine
362     on a sampler channel with connected MIDI device
363 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
364     device connected to a sampler channel to number less then or equal
365     to the index of the port to which the sampler channel is connected.
366 iliev 1296 - The previous bindings were not been disconnected when altering
367     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
368     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
369 iliev 1297 - The active stream/voice count statistic was incorrect.
370 iliev 1298 - notification events were not been sent for some sampler
371     channel changes
372 iliev 1305 - added default min and max values to restrict the number of allowed
373     audio output channels and MIDI input ports
374 iliev 1306 - the connection to the PCM interface is now closed when destroying
375     an audio output device
376 schoenebeck 1332 - files with slash in their path or filename could not be loaded
377 iliev 959
378 schoenebeck 1221 * test cases:
379     - updated and fixed (haven't been touched in a while)
380    
381 schoenebeck 937 Version 0.4.0 (24 November 2006)
382 persson 696
383 schoenebeck 697 * packaging changes:
384 capela 868 - changed deprecated copyright attribute to license; added ldconfig
385     to post-(un)install steps; added devel package for liblinuxsampler;
386     to linuxsampler.spec (RPM)
387 schoenebeck 697 - install necessary development header files for allowing 3rd party
388     applications to link against liblinuxsampler
389     - liblinuxsampler's API documentation can be generated with 'make docs'
390     (Doxygen required)
391 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
392     implementation (currently either an integer math solution or a
393     di-harmonic approximation), automatic detection can be overriden
394     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
395     configure script argument though (mandatory for cross-compilation)
396 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
397     provided some on his own (as CXXFLAGS)
398 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
399     messages
400 schoenebeck 852 - added compile time options to allow disabling the various audio and
401     MIDI drivers
402 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
403     (patch by Ebrahim Mayat)
404 schoenebeck 697
405 persson 696 * Gigasampler format engine:
406 schoenebeck 738 - extensive synthesis optimization
407     (reimplementation of EGs and LFO(s), removed synthesis parameter
408     prerendering and the synthesis parameter matrix in general, splitting
409     each audio fragment into subfragments now where each subfragment uses
410 persson 830 constant pitch and filter coefficients. The volume coefficient is
411     linearly interpolated inside a subfragment, unless
412     --disable-interpolate-volume is set.)
413 persson 696 - fine tuning of the EG modulation parameters
414 persson 729 - improved filter cutoff calculation by adding support for the
415     following gig parameters: Cutoff freq (used when no cutoff
416     controller is defined), Control invert, Minimum cutoff, Velocity
417 persson 791 curve and Velocity range. The keyboard tracking now scales
418     cutoff frequency instead of resonance.
419 persson 877 - added support for gig parameter Resonance.
420 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
421 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
422     which can be overridden with --enable-global-attenuation
423 persson 783 - EG fixes: made the length of "attack hold" stage more
424     accurate. Release stage can now start before attack stage
425 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
426     time now has a minimal value to prevent clicks.
427 persson 799 - fixed pitch changes larger than one octave
428 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
429     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
430     all modes can be altered via standard GM messages, that is CC5 for
431     altering portamento time, CC65 for enabling / disabling portamento
432     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
433 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
434     parameter) and crossfade
435 persson 831 - added support for the "attenuation controller threshold" gig
436     parameter
437 persson 832 - added smoothing of volume changes caused by control change
438     messages
439 persson 865 - sample loop parameters are now taken from the DimensionRegion
440     instead of the wave chunk
441     - fixed keyswitching for v3 gigs with a number of keyswitch splits
442     not equal to a power of two
443 persson 877 - reimplementation of the filter algorithm. The new filter is more
444     accurate and supports all gig filter types, including bandreject
445     and lowpass turbo.
446 persson 903 - real support for 24 bit samples - samples are not truncated to
447     16 bits anymore
448     - support for aftertouch (channel pressure, not polyphonic
449     aftertouch)
450 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
451     amplifying from 0)
452 persson 696
453 schoenebeck 711 * LSCP server:
454     - fixed application exit on broken pipe error (fixes bug #20)
455 iliev 793 - fixed the notification messages delay due to lack of
456     network activity (fixes bug #26)
457 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
458     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
459 schoenebeck 711
460 schoenebeck 838 * audio driver:
461     - added aRts audio output driver (by no means RT safe)
462    
463 schoenebeck 775 * MIDI driver:
464     - fixed legacy sysex code which caused dispatching of MIDI SysEx
465     messages several times instead of once
466 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
467     for events (i.e. for offline rendering based MIDI drivers)
468 persson 922 - added checks for bad MIDI data
469 schoenebeck 775
470 schoenebeck 900 * linuxsampler application:
471     - show available sampler engine types on startup
472    
473 schoenebeck 705 * general changes:
474     - support for muting sampler channels and solo mode of the same, two new
475     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
476     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
477     introduced for this, the behavior is the same like on a mixer console
478 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
479     --enable-process-muted-channels which can be used to enable the
480     processing of muted channels.
481 iliev 777 - support for sostenuto pedal
482 iliev 779 - support for monitoring the total number of active voices
483 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
484     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
485 persson 835 - fixed some memory management errors
486 persson 841 - fixed some concurrency problems that could lead to crashes when
487     LSCP commands were executed
488 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
489     sampler channel (fixes bug #36)
490 schoenebeck 705
491 schoenebeck 692 Version 0.3.3 (15 July 2005)
492 schoenebeck 686
493     * packaging changes:
494     - fixed compilation with gcc 4.0
495    
496 schoenebeck 687 * Gigasampler format engine:
497     - LFO preprocessing was performed even though the respective LFO was
498     disabled by the instrument patch (minor efficiency fix)
499 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
500     for volume ramp downs in the same fragment (needed for current voice
501     stealing implementation) then simply inform the user with a warning
502     about possible click sounds and reduce the volume ramp down
503     appropriately instead of cancelling the audio device connection
504 schoenebeck 687
505 schoenebeck 677 Version 0.3.2 (24 June 2005)
506 schoenebeck 609
507     * packaging changes:
508     - updated autotools build files to compile on OS X
509     (conditional compilation of CoreMIDI and MidiShare drivers)
510 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
511     './configure --disable-asm' (definitely not recommended)
512 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
513     - require automake (>= 1.5) for 'make -f Makefile.cvs'
514     (due to 'dist-bzip2' automake option)
515 schoenebeck 649
516     * Gigasampler format engine:
517     - support for the gig parameters for "release velocity response" curves
518     - fine tuning of the EGADSR envelope
519     - volume of release triggered samples now depends on note-on velocity,
520     note length and gig parameter "release trigger decay" instead of
521     note-off velocity.
522 schoenebeck 663 - revised voice stealing
523     (fixes crash and endless loop caused by voice stealing)
524 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
525 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
526     instead of when the respective voice is actually launched
527     (fixes undefined behavior if stolen voices belonged to a key group -
528     this case was followed by a "killed voice survived" error message)
529 schoenebeck 669 - fixed minor issue with null/silence samples
530     (those stole voices even though they don't need a voice at all which
531     resulted in "voice stealing didn't work out" messages)
532 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
533     instrument or audio output device change
534 schoenebeck 654
535 schoenebeck 620 * LSCP server:
536 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
537 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
538 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
539 schoenebeck 609
540 schoenebeck 668 * linuxsampler application:
541     - added command line parameters --lscp-addr and --lscp-port to override
542     default IP address and port of LSCP server
543    
544 schoenebeck 579 Version 0.3.1 (24 May 2005)
545    
546     * initial release
