* applied old fixes from Benno to the ASIO driver that were included
  in the previous binary release but accidentally never committed to
  CVS (fixes #117)

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 persson 1888 - applied old fixes to the ASIO driver that were included in the
66     previous binary release but accidentally never committed to CVS
67     (fixes #117)
68 schoenebeck 1599
69 persson 1651 * MIDI driver:
70     - added JACK MIDI driver
71 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
72     want to (mis)use it for some purpose ("fixed" in all current MIDI
73     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
74 persson 1887 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, Mme,
75     CoreMidi or AU
76 persson 1651
77 schoenebeck 1604 * instruments database:
78 iliev 1603 - avoid time consuming samples scanning when adding instruments
79     to the instruments database
80 iliev 1727 - added support for handling lost files in the instruments database
81 iliev 1781 - Implemented option for adding instruments in separate directories
82     in the instruments database
83     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
84 iliev 1603
85 persson 1644 * Gigasampler format engine:
86     - fixed a memory leak that could happen when a channel was deleted
87     while notes were playing
88 persson 1646 - made it possible to load an instrument even if the audio thread
89     isn't running
90 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
91     enough for piano gigs with pedal noise samples
92 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
93     respective FX send MIDI controller was used
94 schoenebeck 1724 - added support for GM global device volume SysEx message
95 schoenebeck 1762 (can be selected at compile time to either apply globally to the
96     whole sampler [default] or only to the sampler channels that are
97     connected to the respective MIDI input port the SysEx message arrived
98     on)
99 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
100     sometimes wrongly killed in the same buffer, causing no sound to
101     be played
102 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
103     which is usally used to switch a part between chromatic sounds and
104     drumkit sounds (as opposed to their common default setting of MIDI
105     part 10 being a drumkit part and all other ones chromatic parts), in
106     LS however one can switch between the first 16 MIDI instrument maps
107     defined for the sampler
108 persson 1764 - made it possible to create multiple sample channels even if the
109     audio thread isn't running
110 persson 1844 - fixed crash when removing channel with active voices (#116)
111 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
112     un-cache the respective sample if it's really not used by any
113     sampler engine anymore
114     - re-cache samples in case they were changed by an instrument editor,
115     e.g. when a sample was added while playing (#82)
116 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
117     same time stamp as the voice's note-on event and occured both in the
118     same audio fragment cycle (fixes bug #112)
119 persson 1858 - added support for the "fine tune" and "pitch bend range"
120     instrument-level gig parameters
121     - fixed minor artifacts in pitch bend handling
122 schoenebeck 1860 - added support for GS Reset SysEx message
123 persson 1862 - allow gig files to use unlimited downward pitch shifting
124     - added a limit check for upward pitch shifting
125 persson 1644
126 schoenebeck 1687 * LSCP server:
127     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
128     react on MIDI data arriving on certain sampler channels (so far only
129     Note-On and Note-Off events are sent via this LSCP event)
130 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
131     react on MIDI data arriving on certain MIDI input devices (so far only
132     Note-On and Note-Off events are sent via this LSCP event)
133 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
134     SET DB_INSTRUMENT FILE_PATH
135 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
136     frontends to send MIDI messages to specific sampler channel
137     - added two additional fields to GET FILE INSTRUMENT INFO command -
138     KEY_BINDINGS and KEYSWITCH_BINDINGS
139 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
140     was incorrect
141 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
142 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
143     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
144     be triggered respectively
145     - added new LSCP command "SET STREAMS" to globally alter the maximum
146     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
147     which will be triggered respectively
148 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
149     a gigedit file dialog is opened)
150 iliev 1848 - close all connections when LSCPServer is deleted
151 iliev 1882 - hard close of all sockets on exit
152 schoenebeck 1687
153 iliev 1761 * Bug fixes:
154     - fixed a crash which occurs when removing a sampler channel waiting
155     to start instrument loading after another channel
156 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
157     instrument loading in progress (bug #113)
158 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
159     instrument with PERSISTENT load mode
160 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
161     - fixed memory leaks when issuing the following LSCP commands:
162     GET AUDIO_OUTPUT_DRIVER INFO
163     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
164     GET MIDI_INPUT_DRIVER INFO
165     GET MIDI_INPUT_DRIVER_PARAMETER INFO
166     - fixed possible compilation error when sqlite is not present
167 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
168 iliev 1847 - fixed crash when changing the audio output device of a sampler
169     channel with loaded instrument and start playing notes
170 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
171 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
172     PowerPC, which probably could cause crashes on that platform
173 iliev 1761
174    
175 schoenebeck 1560 Version 0.5.1 (6 December 2007)
176 schoenebeck 1454
177     * packaging changes:
178     - added autoconf checks for pthread library
179     - added autoconf check for pthread bug found on certain NPTL-enabled
180     glibc versions (see Gentoo bug report #194076)
181 senoner 1502 - added autoconf checks for MS Windows
182 schoenebeck 1454
183 persson 1455 * general changes:
184     - bugfix: the thread used by an editor plugin didn't die when the
185     editor closed
186 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
187     out all the space. operator--() did not apply size_mask after
188     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
189     order to avoid problems with the _NonVolatileReader functions.
190     - bugfix: Stream.h: added a missing divide by BytesPerSample in
191     GetWriteSpace(). Since this function is currently only used in
192     the stream's qsort() compare function, it didn't trigger any
193     bugs.
194     - Resampler.h, Synthesizer.h: cubic interpolation now works in
195     24bit mode too. Faster method to read 24bit words on little
196     endian machines (x86): replaced 3 byte reads + shifts with a 1
197     unaligned 32bit read and shift
198     - experimental support for MS Windows (MIDI input via MME, AUDIO
199     output via ASIO)
200     - made handling of SIGINT signal (Ctrl-C) a bit more robust
201 iliev 1541 - support for monitoring the total number of active disk streams
202     (new LSCP commands: GET TOTAL_STREAM_COUNT,
203     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
204 persson 1455
205 senoner 1500 * AUDIO driver:
206 persson 1534 - added Windows ASIO low latency audio driver
207 senoner 1500
208 senoner 1485 * MIDI driver:
209 schoenebeck 1495 - added MME Windows MIDI driver
210 senoner 1485
211 schoenebeck 1471 * LSCP server:
212     - added support for Windows style path / filenames, however with
213     forward slash path separators instead of backslash
214     (i.e. "C:/foo/bar.gig")
215 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
216     apostrophes as well
217 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
218     "LIST FILE INSTRUMENTS <file>" and
219     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
220     about an arbitrary instrument file on the system where the sampler is
221     running on
222 schoenebeck 1471
223 schoenebeck 1424 Version 0.5.0 (15 October 2007)
224 schoenebeck 947
225 schoenebeck 1065 * packaging changes:
226 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
227     API header files anymore
228 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
229     the Doxygen API documentation (explicitly listed in Doxyfile.in)
230 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
231     capable to execute our autoconf environment, thus no need anymore
232     to maintain the compile time configuration file (osx/version.h) for
233     OSX manually (patch by Toshi Nagata)
234 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
235     parameters
236 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
237     C++ API header files, all implementation internal global definitions
238     are now in global_private.h
239     - atomic.h is not exposed to the C++ API anymore
240     - no need to include config.h anymore for using LS's API header files
241     - fixed warnings in API doc generation
242 schoenebeck 1065
243 schoenebeck 947 * general changes:
244     - replaced the old, confusing MIDI program change mechanism by a
245     flexible MIDI instrument mapper which allows to map arbitrary
246 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
247 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
248     loaded on the respective channel when such MIDI program change
249     messages arrive, beside that, each entry allows to define a life-time
250     strategy for the instrument, so the user can define whether the
251     instrument should i.e. be permanently loaded (to be able to switch
252     quickly among sounds) or i.e. loaded just on demand when the
253     respective program change arrives (to safe RAM space), as well as a
254     global volume factor for each entry, so the user can adjust the volume
255     dynamic of his mapped instrument collection without having to modify
256 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
257     MIDI instrument maps and assign each sampler channel individually
258     a certain map, so that i.e. separation of normal instruments and
259     drumkits is possible
260 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
261     MIDI instrument maps, MIDI instruments, FX sends, global volume.
262 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
263     due to a constant size RingBuffer FIFO which is now replaced by a
264     dynamic (unlimited) size std::list FIFO
265 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
266     output channels for being processed by external effect processors
267     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
268     controllers
269 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
270 iliev 1130 - Implemented new, improved notification system
271 schoenebeck 1149 - fixed compilation errors regarding OSX
272     (patch by Toshi Nagata)
273 iliev 1161 - implemented instruments database
274 iliev 1345 - added support for escape sequences to the instruments database
275 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
276     within the sampler's process (by using instrument editor plugins),
277     you'll notice the new "Registered instrument editors:" message on
278 schoenebeck 1407 startup, added a new LSCP command:
279     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
280 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
281     given sampler channel, the plugin path can be overridden at compile
282     time with ./configure --enable-plugin-dir=/some/dir
283 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
284     in the sampler's process to safely edit instruments while playing
285     without a crash (hopefully) by either suspending single regions
286     wherever possible or if unavoidable whole engine(s)
287 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
288     policy and priority on thread level, set a minimum stack size for
289     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
290     threads simply inherited properties of starting thread instead of
291     setting their own policy and priority
292 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
293     main process did not wait for the stack trace process to finish
294     its output
295 persson 1248 - fixed some minor memory leaks
296 schoenebeck 1259 - reenabled assembly features support, at the moment only for
297     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
298 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
299     register, to avoid relocations in the text segment at runtime)
300 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
301 schoenebeck 947
302     * MIDI driver:
303     - dispatch bank select (MSB and LSB) messages
304    
305 schoenebeck 1049 * audio driver:
306     - the ALSA audio output driver parameters now reflect the correct
307     parameter value ranges for the respective selected sound card
308     (patch by Till Wimmer, a bit fixed and extended)
309    
310 persson 951 * Gigasampler format engine:
311     - if a filter is used and EG2 finishes before EG1, let the voice
312     die when EG2 has finished (this fixes a problem with clicks and
313     voice starvation for some gigs)
314 persson 1038 - playback is no longer disabled during instrument loading
315     - all notes playing on a channel that changes its instrument keep
316     playing with the old instrument until they get a note off
317     command
318 persson 1039 - EG fix: a release value of zero could cause noises or crash
319 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
320 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
321     above max sustain level, which means that there is a decay phase
322     even if sustain is 100%
323 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
324     noises or crashes
325 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
326 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
327     supplied to the configure script (fixes #46)
328 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
329     instead of a fix value
330 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
331     127 (solo mode) only kill voices if the respective mode really
332     changed
333 persson 951
334 schoenebeck 1244 * LSCP server:
335     - fixed compile time error for old Bison versions
336     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
337 schoenebeck 1245 - parser now supports extended ASCII character set
338     (up to ASCII code 255, i.e. includes now umlauts and accents)
339     - filename arguments in LSCP commands now allow to use escape
340     sequences, that is directly literal as one of: \', \", \\, \n, \r,
341     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
342     code value like \xf2) (fixes bug #24)
343 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
344     least one of their text-based parameters (i.e. name, description):
345     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
346     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
347     "SET DB_INSTRUMENT_DIRECTORY NAME",
348     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
349     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
350     "FIND DB_INSTRUMENT_DIRECTORIES"
351 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
352     occured, the unexpected character and the actually expected, possible
353     character(s), the latter only if less than 5 possibilities)
354 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
355     settings
356 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
357     of strings were treated as being one string containing commas
358     (fixes #57)
359 schoenebeck 1244
360 iliev 959 * Bug fixes:
361     - fixed crash occurring on certain LSCP scripts (Bug 39)
362 persson 1038 - another thread safety fix for lscp "load engine" and "set
363     channel audio output device"
364 iliev 1283 - fixed a crash which occurs when reassigning the same engine
365     on a sampler channel with connected MIDI device
366 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
367     device connected to a sampler channel to number less then or equal
368     to the index of the port to which the sampler channel is connected.
369 iliev 1296 - The previous bindings were not been disconnected when altering
370     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
371     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
372 iliev 1297 - The active stream/voice count statistic was incorrect.
373 iliev 1298 - notification events were not been sent for some sampler
374     channel changes
375 iliev 1305 - added default min and max values to restrict the number of allowed
376     audio output channels and MIDI input ports
377 iliev 1306 - the connection to the PCM interface is now closed when destroying
378     an audio output device
379 schoenebeck 1332 - files with slash in their path or filename could not be loaded
380 iliev 959
381 schoenebeck 1221 * test cases:
382     - updated and fixed (haven't been touched in a while)
383    
384 schoenebeck 937 Version 0.4.0 (24 November 2006)
385 persson 696
386 schoenebeck 697 * packaging changes:
387 capela 868 - changed deprecated copyright attribute to license; added ldconfig
388     to post-(un)install steps; added devel package for liblinuxsampler;
389     to linuxsampler.spec (RPM)
390 schoenebeck 697 - install necessary development header files for allowing 3rd party
391     applications to link against liblinuxsampler
392     - liblinuxsampler's API documentation can be generated with 'make docs'
393     (Doxygen required)
394 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
395     implementation (currently either an integer math solution or a
396     di-harmonic approximation), automatic detection can be overriden
397     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
398     configure script argument though (mandatory for cross-compilation)
399 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
400     provided some on his own (as CXXFLAGS)
401 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
402     messages
403 schoenebeck 852 - added compile time options to allow disabling the various audio and
404     MIDI drivers
405 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
406     (patch by Ebrahim Mayat)
407 schoenebeck 697
408 persson 696 * Gigasampler format engine:
409 schoenebeck 738 - extensive synthesis optimization
410     (reimplementation of EGs and LFO(s), removed synthesis parameter
411     prerendering and the synthesis parameter matrix in general, splitting
412     each audio fragment into subfragments now where each subfragment uses
413 persson 830 constant pitch and filter coefficients. The volume coefficient is
414     linearly interpolated inside a subfragment, unless
415     --disable-interpolate-volume is set.)
416 persson 696 - fine tuning of the EG modulation parameters
417 persson 729 - improved filter cutoff calculation by adding support for the
418     following gig parameters: Cutoff freq (used when no cutoff
419     controller is defined), Control invert, Minimum cutoff, Velocity
420 persson 791 curve and Velocity range. The keyboard tracking now scales
421     cutoff frequency instead of resonance.
422 persson 877 - added support for gig parameter Resonance.
423 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
424 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
425     which can be overridden with --enable-global-attenuation
426 persson 783 - EG fixes: made the length of "attack hold" stage more
427     accurate. Release stage can now start before attack stage
428 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
429     time now has a minimal value to prevent clicks.
430 persson 799 - fixed pitch changes larger than one octave
431 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
432     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
433     all modes can be altered via standard GM messages, that is CC5 for
434     altering portamento time, CC65 for enabling / disabling portamento
435     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
436 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
437     parameter) and crossfade
438 persson 831 - added support for the "attenuation controller threshold" gig
439     parameter
440 persson 832 - added smoothing of volume changes caused by control change
441     messages
442 persson 865 - sample loop parameters are now taken from the DimensionRegion
443     instead of the wave chunk
444     - fixed keyswitching for v3 gigs with a number of keyswitch splits
445     not equal to a power of two
446 persson 877 - reimplementation of the filter algorithm. The new filter is more
447     accurate and supports all gig filter types, including bandreject
448     and lowpass turbo.
449 persson 903 - real support for 24 bit samples - samples are not truncated to
450     16 bits anymore
451     - support for aftertouch (channel pressure, not polyphonic
452     aftertouch)
453 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
454     amplifying from 0)
455 persson 696
456 schoenebeck 711 * LSCP server:
457     - fixed application exit on broken pipe error (fixes bug #20)
458 iliev 793 - fixed the notification messages delay due to lack of
459     network activity (fixes bug #26)
460 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
461     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
462 schoenebeck 711
463 schoenebeck 838 * audio driver:
464     - added aRts audio output driver (by no means RT safe)
465    
466 schoenebeck 775 * MIDI driver:
467     - fixed legacy sysex code which caused dispatching of MIDI SysEx
468     messages several times instead of once
469 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
470     for events (i.e. for offline rendering based MIDI drivers)
471 persson 922 - added checks for bad MIDI data
472 schoenebeck 775
473 schoenebeck 900 * linuxsampler application:
474     - show available sampler engine types on startup
475    
476 schoenebeck 705 * general changes:
477     - support for muting sampler channels and solo mode of the same, two new
478     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
479     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
480     introduced for this, the behavior is the same like on a mixer console
481 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
482     --enable-process-muted-channels which can be used to enable the
483     processing of muted channels.
484 iliev 777 - support for sostenuto pedal
485 iliev 779 - support for monitoring the total number of active voices
486 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
487     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
488 persson 835 - fixed some memory management errors
489 persson 841 - fixed some concurrency problems that could lead to crashes when
490     LSCP commands were executed
491 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
492     sampler channel (fixes bug #36)
493 schoenebeck 705
494 schoenebeck 692 Version 0.3.3 (15 July 2005)
495 schoenebeck 686
496     * packaging changes:
497     - fixed compilation with gcc 4.0
498    
499 schoenebeck 687 * Gigasampler format engine:
500     - LFO preprocessing was performed even though the respective LFO was
501     disabled by the instrument patch (minor efficiency fix)
502 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
503     for volume ramp downs in the same fragment (needed for current voice
504     stealing implementation) then simply inform the user with a warning
505     about possible click sounds and reduce the volume ramp down
506     appropriately instead of cancelling the audio device connection
507 schoenebeck 687
508 schoenebeck 677 Version 0.3.2 (24 June 2005)
509 schoenebeck 609
510     * packaging changes:
511     - updated autotools build files to compile on OS X
512     (conditional compilation of CoreMIDI and MidiShare drivers)
513 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
514     './configure --disable-asm' (definitely not recommended)
515 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
516     - require automake (>= 1.5) for 'make -f Makefile.cvs'
517     (due to 'dist-bzip2' automake option)
518 schoenebeck 649
519     * Gigasampler format engine:
520     - support for the gig parameters for "release velocity response" curves
521     - fine tuning of the EGADSR envelope
522     - volume of release triggered samples now depends on note-on velocity,
523     note length and gig parameter "release trigger decay" instead of
524     note-off velocity.
525 schoenebeck 663 - revised voice stealing
526     (fixes crash and endless loop caused by voice stealing)
527 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
528 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
529     instead of when the respective voice is actually launched
530     (fixes undefined behavior if stolen voices belonged to a key group -
531     this case was followed by a "killed voice survived" error message)
532 schoenebeck 669 - fixed minor issue with null/silence samples
533     (those stole voices even though they don't need a voice at all which
534     resulted in "voice stealing didn't work out" messages)
535 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
536     instrument or audio output device change
537 schoenebeck 654
538 schoenebeck 620 * LSCP server:
539 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
540 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
541 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
542 schoenebeck 609
543 schoenebeck 668 * linuxsampler application:
544     - added command line parameters --lscp-addr and --lscp-port to override
545     default IP address and port of LSCP server
546    
547 schoenebeck 579 Version 0.3.1 (24 May 2005)
548    
549     * initial release
