File size: 28555 byte(s)
* fixed a memory management error which could cause a crash when a
  plugin was unloaded
* minor fixes in ASIO and MME drivers for win64

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 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
69     win64)
70 schoenebeck 1599
71 persson 1651 * MIDI driver:
72     - added JACK MIDI driver
73 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
74     want to (mis)use it for some purpose ("fixed" in all current MIDI
75     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
76 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
77 persson 1887 CoreMidi or AU
78 persson 1889 - fixed mingw-w64 compilation error in MME driver
79 persson 1651
80 schoenebeck 1604 * instruments database:

82     to the instruments database
83 iliev 1727 - added support for handling lost files in the instruments database
84 iliev 1781 - Implemented option for adding instruments in separate directories
85     in the instruments database
86     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
87 iliev 1603
88 persson 1644 * Gigasampler format engine:
89     - fixed a memory leak that could happen when a channel was deleted
90     while notes were playing
91 persson 1646 - made it possible to load an instrument even if the audio thread
92     isn't running
93 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
94     enough for piano gigs with pedal noise samples
95 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
96     respective FX send MIDI controller was used
97 schoenebeck 1724 - added support for GM global device volume SysEx message
98 schoenebeck 1762 (can be selected at compile time to either apply globally to the
99     whole sampler [default] or only to the sampler channels that are
100     connected to the respective MIDI input port the SysEx message arrived
101     on)
102 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
103     sometimes wrongly killed in the same buffer, causing no sound to
104     be played
105 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
106     which is usally used to switch a part between chromatic sounds and
107     drumkit sounds (as opposed to their common default setting of MIDI
108     part 10 being a drumkit part and all other ones chromatic parts), in
109     LS however one can switch between the first 16 MIDI instrument maps
110     defined for the sampler
111 persson 1764 - made it possible to create multiple sample channels even if the
112     audio thread isn't running
113 persson 1844 - fixed crash when removing channel with active voices (#116)
114 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
115     un-cache the respective sample if it's really not used by any
116     sampler engine anymore
117     - re-cache samples in case they were changed by an instrument editor,
118     e.g. when a sample was added while playing (#82)
119 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
120     same time stamp as the voice's note-on event and occured both in the
121     same audio fragment cycle (fixes bug #112)
122 persson 1858 - added support for the "fine tune" and "pitch bend range"
123     instrument-level gig parameters
124     - fixed minor artifacts in pitch bend handling
125 schoenebeck 1860 - added support for GS Reset SysEx message
126 persson 1862 - allow gig files to use unlimited downward pitch shifting
127     - added a limit check for upward pitch shifting
128 persson 1644
129 schoenebeck 1687 * LSCP server:
130     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
131     react on MIDI data arriving on certain sampler channels (so far only
132     Note-On and Note-Off events are sent via this LSCP event)
133 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
134     react on MIDI data arriving on certain MIDI input devices (so far only
135     Note-On and Note-Off events are sent via this LSCP event)
136 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
137     SET DB_INSTRUMENT FILE_PATH
138 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
139     frontends to send MIDI messages to specific sampler channel
140     - added two additional fields to GET FILE INSTRUMENT INFO command -
141     KEY_BINDINGS and KEYSWITCH_BINDINGS
142 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
143     was incorrect
144 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
145 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
146     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
147     be triggered respectively
148     - added new LSCP command "SET STREAMS" to globally alter the maximum
149     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
150     which will be triggered respectively
151 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
152     a gigedit file dialog is opened)
153 iliev 1848 - close all connections when LSCPServer is deleted
154 iliev 1882 - hard close of all sockets on exit
155 schoenebeck 1687
156 iliev 1761 * Bug fixes:
157     - fixed a crash which occurs when removing a sampler channel waiting
158     to start instrument loading after another channel
159 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
160     instrument loading in progress (bug #113)
161 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
162     instrument with PERSISTENT load mode
163 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
164     - fixed memory leaks when issuing the following LSCP commands:
165     GET AUDIO_OUTPUT_DRIVER INFO
166     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
167     GET MIDI_INPUT_DRIVER INFO
168     GET MIDI_INPUT_DRIVER_PARAMETER INFO
169     - fixed possible compilation error when sqlite is not present
170 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
171 iliev 1847 - fixed crash when changing the audio output device of a sampler
172     channel with loaded instrument and start playing notes
173 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
174 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
175     PowerPC, which probably could cause crashes on that platform
176 persson 1889 - fixed a memory management error which could cause a crash when a
177     plugin was unloaded
178 iliev 1761
179    
180 schoenebeck 1560 Version 0.5.1 (6 December 2007)
181 schoenebeck 1454
182     * packaging changes:
183     - added autoconf checks for pthread library
184     - added autoconf check for pthread bug found on certain NPTL-enabled
185     glibc versions (see Gentoo bug report #194076)
186 senoner 1502 - added autoconf checks for MS Windows
187 schoenebeck 1454
188 persson 1455 * general changes:
189     - bugfix: the thread used by an editor plugin didn't die when the
190     editor closed
191 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
192     out all the space. operator--() did not apply size_mask after
193     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
194     order to avoid problems with the _NonVolatileReader functions.
195     - bugfix: Stream.h: added a missing divide by BytesPerSample in
196     GetWriteSpace(). Since this function is currently only used in
197     the stream's qsort() compare function, it didn't trigger any
198     bugs.
199     - Resampler.h, Synthesizer.h: cubic interpolation now works in
200     24bit mode too. Faster method to read 24bit words on little
201     endian machines (x86): replaced 3 byte reads + shifts with a 1
202     unaligned 32bit read and shift
203     - experimental support for MS Windows (MIDI input via MME, AUDIO
204     output via ASIO)
205     - made handling of SIGINT signal (Ctrl-C) a bit more robust
206 iliev 1541 - support for monitoring the total number of active disk streams
207     (new LSCP commands: GET TOTAL_STREAM_COUNT,
208     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
209 persson 1455
210 senoner 1500 * AUDIO driver:
211 persson 1534 - added Windows ASIO low latency audio driver
212 senoner 1500
213 senoner 1485 * MIDI driver:
214 schoenebeck 1495 - added MME Windows MIDI driver
215 senoner 1485
216 schoenebeck 1471 * LSCP server:
217     - added support for Windows style path / filenames, however with
218     forward slash path separators instead of backslash
219     (i.e. "C:/foo/bar.gig")
220 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
221     apostrophes as well
222 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
223     "LIST FILE INSTRUMENTS <file>" and
224     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
225     about an arbitrary instrument file on the system where the sampler is
226     running on
227 schoenebeck 1471
228 schoenebeck 1424 Version 0.5.0 (15 October 2007)
229 schoenebeck 947
230 schoenebeck 1065 * packaging changes:
231 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
232     API header files anymore
233 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
234     the Doxygen API documentation (explicitly listed in Doxyfile.in)
235 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
236     capable to execute our autoconf environment, thus no need anymore
237     to maintain the compile time configuration file (osx/version.h) for
238     OSX manually (patch by Toshi Nagata)
239 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
240     parameters
241 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
242     C++ API header files, all implementation internal global definitions
243     are now in global_private.h
244     - atomic.h is not exposed to the C++ API anymore
245     - no need to include config.h anymore for using LS's API header files
246     - fixed warnings in API doc generation
247 schoenebeck 1065
248 schoenebeck 947 * general changes:
249     - replaced the old, confusing MIDI program change mechanism by a
250     flexible MIDI instrument mapper which allows to map arbitrary
251 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
252 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
253     loaded on the respective channel when such MIDI program change
254     messages arrive, beside that, each entry allows to define a life-time
255     strategy for the instrument, so the user can define whether the
256     instrument should i.e. be permanently loaded (to be able to switch
257     quickly among sounds) or i.e. loaded just on demand when the
258     respective program change arrives (to safe RAM space), as well as a
259     global volume factor for each entry, so the user can adjust the volume
260     dynamic of his mapped instrument collection without having to modify
261 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
262     MIDI instrument maps and assign each sampler channel individually
263     a certain map, so that i.e. separation of normal instruments and
264     drumkits is possible
265 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
266     MIDI instrument maps, MIDI instruments, FX sends, global volume.
267 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
268     due to a constant size RingBuffer FIFO which is now replaced by a
269     dynamic (unlimited) size std::list FIFO
270 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
271     output channels for being processed by external effect processors
272     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
273     controllers
274 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
275 iliev 1130 - Implemented new, improved notification system
276 schoenebeck 1149 - fixed compilation errors regarding OSX
277     (patch by Toshi Nagata)
278 iliev 1161 - implemented instruments database
279 iliev 1345 - added support for escape sequences to the instruments database
280 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
281     within the sampler's process (by using instrument editor plugins),
282     you'll notice the new "Registered instrument editors:" message on
283 schoenebeck 1407 startup, added a new LSCP command:
284     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
285 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
286     given sampler channel, the plugin path can be overridden at compile
287     time with ./configure --enable-plugin-dir=/some/dir
288 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
289     in the sampler's process to safely edit instruments while playing
290     without a crash (hopefully) by either suspending single regions
291     wherever possible or if unavoidable whole engine(s)
292 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
293     policy and priority on thread level, set a minimum stack size for
294     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
295     threads simply inherited properties of starting thread instead of
296     setting their own policy and priority
297 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
298     main process did not wait for the stack trace process to finish
299     its output
300 persson 1248 - fixed some minor memory leaks
301 schoenebeck 1259 - reenabled assembly features support, at the moment only for
302     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
303 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
304     register, to avoid relocations in the text segment at runtime)
305 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
306 schoenebeck 947
307     * MIDI driver:
308     - dispatch bank select (MSB and LSB) messages
309    
310 schoenebeck 1049 * audio driver:
311     - the ALSA audio output driver parameters now reflect the correct
312     parameter value ranges for the respective selected sound card
313     (patch by Till Wimmer, a bit fixed and extended)
314    
315 persson 951 * Gigasampler format engine:
316     - if a filter is used and EG2 finishes before EG1, let the voice
317     die when EG2 has finished (this fixes a problem with clicks and
318     voice starvation for some gigs)
319 persson 1038 - playback is no longer disabled during instrument loading
320     - all notes playing on a channel that changes its instrument keep
321     playing with the old instrument until they get a note off
322     command
323 persson 1039 - EG fix: a release value of zero could cause noises or crash
324 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
325 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
326     above max sustain level, which means that there is a decay phase
327     even if sustain is 100%
328 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
329     noises or crashes
330 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
331 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
332     supplied to the configure script (fixes #46)
333 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
334     instead of a fix value
335 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
336     127 (solo mode) only kill voices if the respective mode really
337     changed
338 persson 951
339 schoenebeck 1244 * LSCP server:
340     - fixed compile time error for old Bison versions
341     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
342 schoenebeck 1245 - parser now supports extended ASCII character set
343     (up to ASCII code 255, i.e. includes now umlauts and accents)
344     - filename arguments in LSCP commands now allow to use escape
345     sequences, that is directly literal as one of: \', \", \\, \n, \r,
346     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
347     code value like \xf2) (fixes bug #24)
348 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
349     least one of their text-based parameters (i.e. name, description):
350     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
351     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
352     "SET DB_INSTRUMENT_DIRECTORY NAME",
353     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
354     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
355     "FIND DB_INSTRUMENT_DIRECTORIES"
356 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
357     occured, the unexpected character and the actually expected, possible
358     character(s), the latter only if less than 5 possibilities)
359 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
360     settings
361 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
362     of strings were treated as being one string containing commas
363     (fixes #57)
364 schoenebeck 1244
365 iliev 959 * Bug fixes:
366     - fixed crash occurring on certain LSCP scripts (Bug 39)
367 persson 1038 - another thread safety fix for lscp "load engine" and "set
368     channel audio output device"
369 iliev 1283 - fixed a crash which occurs when reassigning the same engine
370     on a sampler channel with connected MIDI device
371 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
372     device connected to a sampler channel to number less then or equal
373     to the index of the port to which the sampler channel is connected.
374 iliev 1296 - The previous bindings were not been disconnected when altering
375     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
376     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
377 iliev 1297 - The active stream/voice count statistic was incorrect.
378 iliev 1298 - notification events were not been sent for some sampler
379     channel changes
380 iliev 1305 - added default min and max values to restrict the number of allowed
381     audio output channels and MIDI input ports
382 iliev 1306 - the connection to the PCM interface is now closed when destroying
383     an audio output device
384 schoenebeck 1332 - files with slash in their path or filename could not be loaded
385 iliev 959
386 schoenebeck 1221 * test cases:
387     - updated and fixed (haven't been touched in a while)
388    
389 schoenebeck 937 Version 0.4.0 (24 November 2006)
390 persson 696
391 schoenebeck 697 * packaging changes:
392 capela 868 - changed deprecated copyright attribute to license; added ldconfig
393     to post-(un)install steps; added devel package for liblinuxsampler;
394     to linuxsampler.spec (RPM)
395 schoenebeck 697 - install necessary development header files for allowing 3rd party
396     applications to link against liblinuxsampler
397     - liblinuxsampler's API documentation can be generated with 'make docs'
398     (Doxygen required)
399 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
400     implementation (currently either an integer math solution or a
401     di-harmonic approximation), automatic detection can be overriden
402     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
403     configure script argument though (mandatory for cross-compilation)
404 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
405     provided some on his own (as CXXFLAGS)
406 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
407     messages
408 schoenebeck 852 - added compile time options to allow disabling the various audio and
409     MIDI drivers
410 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
411     (patch by Ebrahim Mayat)
412 schoenebeck 697
413 persson 696 * Gigasampler format engine:
414 schoenebeck 738 - extensive synthesis optimization
415     (reimplementation of EGs and LFO(s), removed synthesis parameter
416     prerendering and the synthesis parameter matrix in general, splitting
417     each audio fragment into subfragments now where each subfragment uses
418 persson 830 constant pitch and filter coefficients. The volume coefficient is
419     linearly interpolated inside a subfragment, unless
420     --disable-interpolate-volume is set.)
421 persson 696 - fine tuning of the EG modulation parameters
422 persson 729 - improved filter cutoff calculation by adding support for the
423     following gig parameters: Cutoff freq (used when no cutoff
424     controller is defined), Control invert, Minimum cutoff, Velocity
425 persson 791 curve and Velocity range. The keyboard tracking now scales
426     cutoff frequency instead of resonance.
427 persson 877 - added support for gig parameter Resonance.
428 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
429 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
430     which can be overridden with --enable-global-attenuation
431 persson 783 - EG fixes: made the length of "attack hold" stage more
432     accurate. Release stage can now start before attack stage
433 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
434     time now has a minimal value to prevent clicks.
435 persson 799 - fixed pitch changes larger than one octave
436 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
437     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
438     all modes can be altered via standard GM messages, that is CC5 for
439     altering portamento time, CC65 for enabling / disabling portamento
440     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
441 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
442     parameter) and crossfade
443 persson 831 - added support for the "attenuation controller threshold" gig
444     parameter
445 persson 832 - added smoothing of volume changes caused by control change
446     messages
447 persson 865 - sample loop parameters are now taken from the DimensionRegion
448     instead of the wave chunk
449     - fixed keyswitching for v3 gigs with a number of keyswitch splits
450     not equal to a power of two
451 persson 877 - reimplementation of the filter algorithm. The new filter is more
452     accurate and supports all gig filter types, including bandreject
453     and lowpass turbo.
454 persson 903 - real support for 24 bit samples - samples are not truncated to
455     16 bits anymore
456     - support for aftertouch (channel pressure, not polyphonic
457     aftertouch)
458 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
459     amplifying from 0)
460 persson 696
461 schoenebeck 711 * LSCP server:
462     - fixed application exit on broken pipe error (fixes bug #20)
463 iliev 793 - fixed the notification messages delay due to lack of
464     network activity (fixes bug #26)
465 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
466     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
467 schoenebeck 711
468 schoenebeck 838 * audio driver:
469     - added aRts audio output driver (by no means RT safe)
470    
471 schoenebeck 775 * MIDI driver:
472     - fixed legacy sysex code which caused dispatching of MIDI SysEx
473     messages several times instead of once
474 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
475     for events (i.e. for offline rendering based MIDI drivers)
476 persson 922 - added checks for bad MIDI data
477 schoenebeck 775
478 schoenebeck 900 * linuxsampler application:
479     - show available sampler engine types on startup
480    
481 schoenebeck 705 * general changes:
482     - support for muting sampler channels and solo mode of the same, two new
483     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
484     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
485     introduced for this, the behavior is the same like on a mixer console
486 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
487     --enable-process-muted-channels which can be used to enable the
488     processing of muted channels.
489 iliev 777 - support for sostenuto pedal
490 iliev 779 - support for monitoring the total number of active voices
491 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
492     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
493 persson 835 - fixed some memory management errors
494 persson 841 - fixed some concurrency problems that could lead to crashes when
495     LSCP commands were executed
496 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
497     sampler channel (fixes bug #36)
498 schoenebeck 705
499 schoenebeck 692 Version 0.3.3 (15 July 2005)
500 schoenebeck 686
501     * packaging changes:
502     - fixed compilation with gcc 4.0
503    
504 schoenebeck 687 * Gigasampler format engine:
505     - LFO preprocessing was performed even though the respective LFO was
506     disabled by the instrument patch (minor efficiency fix)
507 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
508     for volume ramp downs in the same fragment (needed for current voice
509     stealing implementation) then simply inform the user with a warning
510     about possible click sounds and reduce the volume ramp down
511     appropriately instead of cancelling the audio device connection
512 schoenebeck 687
513 schoenebeck 677 Version 0.3.2 (24 June 2005)
514 schoenebeck 609
515     * packaging changes:
516     - updated autotools build files to compile on OS X
517     (conditional compilation of CoreMIDI and MidiShare drivers)
518 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
519     './configure --disable-asm' (definitely not recommended)
520 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
521     - require automake (>= 1.5) for 'make -f Makefile.cvs'
522     (due to 'dist-bzip2' automake option)
523 schoenebeck 649
524     * Gigasampler format engine:
525     - support for the gig parameters for "release velocity response" curves
526     - fine tuning of the EGADSR envelope
527     - volume of release triggered samples now depends on note-on velocity,
528     note length and gig parameter "release trigger decay" instead of
529     note-off velocity.
530 schoenebeck 663 - revised voice stealing
531     (fixes crash and endless loop caused by voice stealing)
532 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
533 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
534     instead of when the respective voice is actually launched
535     (fixes undefined behavior if stolen voices belonged to a key group -
536     this case was followed by a "killed voice survived" error message)
537 schoenebeck 669 - fixed minor issue with null/silence samples
538     (those stole voices even though they don't need a voice at all which
539     resulted in "voice stealing didn't work out" messages)
540 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
541     instrument or audio output device change
542 schoenebeck 654
543 schoenebeck 620 * LSCP server:
544 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
545 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
546 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
547 schoenebeck 609
548 schoenebeck 668 * linuxsampler application:
549     - added command line parameters --lscp-addr and --lscp-port to override
550     default IP address and port of LSCP server
551    
552 schoenebeck 579 Version 0.3.1 (24 May 2005)
553    
554     * initial release
