  driver

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 persson 1895 - minor fix in configure for mmsystem.h detection on MinGW
15 persson 1897 - Windows: look for editor plugins and Fantasia using base
16     directory of liblinuxsampler dll
17 schoenebeck 1639
18 schoenebeck 1601 * general changes:
19     - bugfix: on some POSIX systems instrument editor plugins refused to
20     load as we used a non-portable Linux specific struct field
21     (fixes bug #70, patch by Ronald Baljeu)
22 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
23     plugin DLL on Windows systems failed
24 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded
25     - optimized the SynchronizedConfig class so it doesn't wait
26     unnecessarily long after an update
27 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
28     events (e.g. to highlight the pressed keys on the virtual keyboard
29     of gigedit)
30 schoenebeck 1659 - added support for triggering notes by instrument editors (see above)
31 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
32 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation
33     is only used by very few systems, most pick the int math
34     implementation, which is usually faster)
35 persson 1748 - fixes for audio drivers with varying buffer sizes
36 persson 1777 - experimental support for running LinuxSampler as a DSSI, LV2 and
37     VST plugin
38 iliev 1789 - notification events for stream/voice count statistics are now sent
39     only when there are actual changes
40 persson 1790 - added memory ordering constraints to improve stability on
41     multi-core and multi-cpu systems
42 schoenebeck 1800 - maximum voices and disk streams can now be altered at runtime
43 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
44 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
45     be switched on by command line option "--stacktrace" (the automatic
46     stacktrace mechanism seems to be broken on most systems at the moment)
47 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
48     a pointer to the launched InstrumentEditor object
49 schoenebeck 1876 - added optional 3rd party user data parameter for following
50     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
51     InstrumentEditor::Launch(),
52     InstrumentManager::LaunchInstrumentEditor()
53 persson 1887 - theoretical fix: made SynchronizedConfig follow C++0x memory
54     model more strictly
55 persson 1895 - fixes for using large audio device buffers
56 schoenebeck 1601
57 schoenebeck 1599 * audio driver:
58     - removed the nonsense audio channel constraint (which was hard coded to
59     max. 100 audio channels) for most audio drivers
60 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
61     opposed to the LSCP specs
62 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
63     reflected the wrong value
64 persson 1644 - fixed a memory management bug in ASIO driver
65 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used
66 persson 1777 - JACK: use jack_client_open instead of the deprecated
67 persson 1748 jack_client_new
68 iliev 1829 - added (experimental) CoreAudio driver
69 persson 1888 - applied old fixes to the ASIO driver that were included in the
70     previous binary release but accidentally never committed to CVS
71     (fixes #117)
72 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
73     win64)
74 persson 1895 - VST: added support for sample rate and buffer size changes
75     - VST: close editor (Fantasia) when the VST is removed
76 schoenebeck 1599
77 persson 1651 * MIDI driver:
78     - added JACK MIDI driver
79 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
80     want to (mis)use it for some purpose ("fixed" in all current MIDI
81     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
82 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
83 persson 1887 CoreMidi or AU
84 persson 1889 - fixed mingw-w64 compilation error in MME driver
85 persson 1651
86 schoenebeck 1604 * instruments database:
87 iliev 1603 - avoid time consuming samples scanning when adding instruments
88     to the instruments database
89 iliev 1727 - added support for handling lost files in the instruments database
90 iliev 1781 - Implemented option for adding instruments in separate directories
91     in the instruments database
92     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
93 iliev 1603
94 persson 1644 * Gigasampler format engine:
95     - fixed a memory leak that could happen when a channel was deleted
96     while notes were playing
97 persson 1646 - made it possible to load an instrument even if the audio thread
98     isn't running
99 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
100     enough for piano gigs with pedal noise samples
101 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
102     respective FX send MIDI controller was used
103 schoenebeck 1724 - added support for GM global device volume SysEx message
104 schoenebeck 1762 (can be selected at compile time to either apply globally to the
105     whole sampler [default] or only to the sampler channels that are
106     connected to the respective MIDI input port the SysEx message arrived
107     on)
108 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
109     sometimes wrongly killed in the same buffer, causing no sound to
110     be played
111 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
112     which is usally used to switch a part between chromatic sounds and
113     drumkit sounds (as opposed to their common default setting of MIDI
114     part 10 being a drumkit part and all other ones chromatic parts), in
115     LS however one can switch between the first 16 MIDI instrument maps
116     defined for the sampler
117 persson 1764 - made it possible to create multiple sample channels even if the
118     audio thread isn't running
119 persson 1844 - fixed crash when removing channel with active voices (#116)
120 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
121     un-cache the respective sample if it's really not used by any
122     sampler engine anymore
123     - re-cache samples in case they were changed by an instrument editor,
124     e.g. when a sample was added while playing (#82)
125 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
126     same time stamp as the voice's note-on event and occured both in the
127     same audio fragment cycle (fixes bug #112)
128 persson 1858 - added support for the "fine tune" and "pitch bend range"
129     instrument-level gig parameters
130     - fixed minor artifacts in pitch bend handling
131 schoenebeck 1860 - added support for GS Reset SysEx message
132 persson 1862 - allow gig files to use unlimited downward pitch shifting
133     - added a limit check for upward pitch shifting
134 persson 1644
135 schoenebeck 1687 * LSCP server:
136     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
137     react on MIDI data arriving on certain sampler channels (so far only
138     Note-On and Note-Off events are sent via this LSCP event)
139 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
140     react on MIDI data arriving on certain MIDI input devices (so far only
141     Note-On and Note-Off events are sent via this LSCP event)
142 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
143     SET DB_INSTRUMENT FILE_PATH
144 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
145     frontends to send MIDI messages to specific sampler channel
146     - added two additional fields to GET FILE INSTRUMENT INFO command -
147     KEY_BINDINGS and KEYSWITCH_BINDINGS
148 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
149     was incorrect
150 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
151 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
152     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
153     be triggered respectively
154     - added new LSCP command "SET STREAMS" to globally alter the maximum
155     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
156     which will be triggered respectively
157 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
158     a gigedit file dialog is opened)
159 iliev 1848 - close all connections when LSCPServer is deleted
160 iliev 1882 - hard close of all sockets on exit
161 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
162     driver
163 schoenebeck 1687
164 iliev 1761 * Bug fixes:
165     - fixed a crash which occurs when removing a sampler channel waiting
166     to start instrument loading after another channel
167 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
168     instrument loading in progress (bug #113)
169 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
170     instrument with PERSISTENT load mode
171 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
172     - fixed memory leaks when issuing the following LSCP commands:
173     GET AUDIO_OUTPUT_DRIVER INFO
174     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
175     GET MIDI_INPUT_DRIVER INFO
176     GET MIDI_INPUT_DRIVER_PARAMETER INFO
177     - fixed possible compilation error when sqlite is not present
178 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
179 iliev 1847 - fixed crash when changing the audio output device of a sampler
180     channel with loaded instrument and start playing notes
181 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
182 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
183     PowerPC, which probably could cause crashes on that platform
184 persson 1889 - fixed a memory management error which could cause a crash when a
185     plugin was unloaded
186 persson 1896 - bugfix: two private structs had the same name, which could cause
187     problems if the linker chose the wrong constructor
188 iliev 1761
189    
190 schoenebeck 1560 Version 0.5.1 (6 December 2007)
191 schoenebeck 1454
192     * packaging changes:
193     - added autoconf checks for pthread library
194     - added autoconf check for pthread bug found on certain NPTL-enabled
195     glibc versions (see Gentoo bug report #194076)
196 senoner 1502 - added autoconf checks for MS Windows
197 schoenebeck 1454
198 persson 1455 * general changes:
199     - bugfix: the thread used by an editor plugin didn't die when the
200     editor closed
201 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
202     out all the space. operator--() did not apply size_mask after
203     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
204     order to avoid problems with the _NonVolatileReader functions.
205     - bugfix: Stream.h: added a missing divide by BytesPerSample in
206     GetWriteSpace(). Since this function is currently only used in
207     the stream's qsort() compare function, it didn't trigger any
208     bugs.
209     - Resampler.h, Synthesizer.h: cubic interpolation now works in
210     24bit mode too. Faster method to read 24bit words on little
211     endian machines (x86): replaced 3 byte reads + shifts with a 1
212     unaligned 32bit read and shift
213     - experimental support for MS Windows (MIDI input via MME, AUDIO
214     output via ASIO)
215     - made handling of SIGINT signal (Ctrl-C) a bit more robust
216 iliev 1541 - support for monitoring the total number of active disk streams
217     (new LSCP commands: GET TOTAL_STREAM_COUNT,
218     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
219 persson 1455
220 senoner 1500 * AUDIO driver:
221 persson 1534 - added Windows ASIO low latency audio driver
222 senoner 1500
223 senoner 1485 * MIDI driver:
224 schoenebeck 1495 - added MME Windows MIDI driver
225 senoner 1485
226 schoenebeck 1471 * LSCP server:
227     - added support for Windows style path / filenames, however with
228     forward slash path separators instead of backslash
229     (i.e. "C:/foo/bar.gig")
230 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
231     apostrophes as well
232 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
233     "LIST FILE INSTRUMENTS <file>" and
234     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
235     about an arbitrary instrument file on the system where the sampler is
236     running on
237 schoenebeck 1471
238 schoenebeck 1424 Version 0.5.0 (15 October 2007)
239 schoenebeck 947
240 schoenebeck 1065 * packaging changes:
241 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
242     API header files anymore
243 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
244     the Doxygen API documentation (explicitly listed in Doxyfile.in)
245 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
246     capable to execute our autoconf environment, thus no need anymore
247     to maintain the compile time configuration file (osx/version.h) for
248     OSX manually (patch by Toshi Nagata)
249 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
250     parameters
251 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
252     C++ API header files, all implementation internal global definitions
253     are now in global_private.h
254     - atomic.h is not exposed to the C++ API anymore
255     - no need to include config.h anymore for using LS's API header files
256     - fixed warnings in API doc generation
257 schoenebeck 1065
258 schoenebeck 947 * general changes:
259     - replaced the old, confusing MIDI program change mechanism by a
260     flexible MIDI instrument mapper which allows to map arbitrary
261 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
262 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
263     loaded on the respective channel when such MIDI program change
264     messages arrive, beside that, each entry allows to define a life-time
265     strategy for the instrument, so the user can define whether the
266     instrument should i.e. be permanently loaded (to be able to switch
267     quickly among sounds) or i.e. loaded just on demand when the
268     respective program change arrives (to safe RAM space), as well as a
269     global volume factor for each entry, so the user can adjust the volume
270     dynamic of his mapped instrument collection without having to modify
271 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
272     MIDI instrument maps and assign each sampler channel individually
273     a certain map, so that i.e. separation of normal instruments and
274     drumkits is possible
275 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
276     MIDI instrument maps, MIDI instruments, FX sends, global volume.
277 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
278     due to a constant size RingBuffer FIFO which is now replaced by a
279     dynamic (unlimited) size std::list FIFO
280 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
281     output channels for being processed by external effect processors
282     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
283     controllers
284 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
285 iliev 1130 - Implemented new, improved notification system
286 schoenebeck 1149 - fixed compilation errors regarding OSX
287     (patch by Toshi Nagata)
288 iliev 1161 - implemented instruments database
289 iliev 1345 - added support for escape sequences to the instruments database
290 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
291     within the sampler's process (by using instrument editor plugins),
292     you'll notice the new "Registered instrument editors:" message on
293 schoenebeck 1407 startup, added a new LSCP command:
294     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
295 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
296     given sampler channel, the plugin path can be overridden at compile
297     time with ./configure --enable-plugin-dir=/some/dir
298 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
299     in the sampler's process to safely edit instruments while playing
300     without a crash (hopefully) by either suspending single regions
301     wherever possible or if unavoidable whole engine(s)
302 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
303     policy and priority on thread level, set a minimum stack size for
304     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
305     threads simply inherited properties of starting thread instead of
306     setting their own policy and priority
307 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
308     main process did not wait for the stack trace process to finish
309     its output
310 persson 1248 - fixed some minor memory leaks
311 schoenebeck 1259 - reenabled assembly features support, at the moment only for
312     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
313 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
314     register, to avoid relocations in the text segment at runtime)
315 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
316 schoenebeck 947
317     * MIDI driver:
318     - dispatch bank select (MSB and LSB) messages
319    
320 schoenebeck 1049 * audio driver:
321     - the ALSA audio output driver parameters now reflect the correct
322     parameter value ranges for the respective selected sound card
323     (patch by Till Wimmer, a bit fixed and extended)
324    
325 persson 951 * Gigasampler format engine:
326     - if a filter is used and EG2 finishes before EG1, let the voice
327     die when EG2 has finished (this fixes a problem with clicks and
328     voice starvation for some gigs)
329 persson 1038 - playback is no longer disabled during instrument loading
330     - all notes playing on a channel that changes its instrument keep
331     playing with the old instrument until they get a note off
332     command
333 persson 1039 - EG fix: a release value of zero could cause noises or crash
334 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
335 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
336     above max sustain level, which means that there is a decay phase
337     even if sustain is 100%
338 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
339     noises or crashes
340 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
341 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
342     supplied to the configure script (fixes #46)
343 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
344     instead of a fix value
345 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
346     127 (solo mode) only kill voices if the respective mode really
347     changed
348 persson 951
349 schoenebeck 1244 * LSCP server:
350     - fixed compile time error for old Bison versions
351     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
352 schoenebeck 1245 - parser now supports extended ASCII character set
353     (up to ASCII code 255, i.e. includes now umlauts and accents)
354     - filename arguments in LSCP commands now allow to use escape
355     sequences, that is directly literal as one of: \', \", \\, \n, \r,
356     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
357     code value like \xf2) (fixes bug #24)
358 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
359     least one of their text-based parameters (i.e. name, description):
360     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
361     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
362     "SET DB_INSTRUMENT_DIRECTORY NAME",
363     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
364     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
365     "FIND DB_INSTRUMENT_DIRECTORIES"
366 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
367     occured, the unexpected character and the actually expected, possible
368     character(s), the latter only if less than 5 possibilities)
369 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
370     settings
371 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
372     of strings were treated as being one string containing commas
373     (fixes #57)
374 schoenebeck 1244
375 iliev 959 * Bug fixes:
376     - fixed crash occurring on certain LSCP scripts (Bug 39)
377 persson 1038 - another thread safety fix for lscp "load engine" and "set
378     channel audio output device"
379 iliev 1283 - fixed a crash which occurs when reassigning the same engine
380     on a sampler channel with connected MIDI device
381 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
382     device connected to a sampler channel to number less then or equal
383     to the index of the port to which the sampler channel is connected.
384 iliev 1296 - The previous bindings were not been disconnected when altering
385     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
386     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
387 iliev 1297 - The active stream/voice count statistic was incorrect.
388 iliev 1298 - notification events were not been sent for some sampler
389     channel changes
390 iliev 1305 - added default min and max values to restrict the number of allowed
391     audio output channels and MIDI input ports
392 iliev 1306 - the connection to the PCM interface is now closed when destroying
393     an audio output device
394 schoenebeck 1332 - files with slash in their path or filename could not be loaded
395 iliev 959
396 schoenebeck 1221 * test cases:
397     - updated and fixed (haven't been touched in a while)
398    
399 schoenebeck 937 Version 0.4.0 (24 November 2006)
400 persson 696
401 schoenebeck 697 * packaging changes:
402 capela 868 - changed deprecated copyright attribute to license; added ldconfig
403     to post-(un)install steps; added devel package for liblinuxsampler;
404     to linuxsampler.spec (RPM)
405 schoenebeck 697 - install necessary development header files for allowing 3rd party
406     applications to link against liblinuxsampler
407     - liblinuxsampler's API documentation can be generated with 'make docs'
408     (Doxygen required)
409 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
410     implementation (currently either an integer math solution or a
411     di-harmonic approximation), automatic detection can be overriden
412     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
413     configure script argument though (mandatory for cross-compilation)
414 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
415     provided some on his own (as CXXFLAGS)
416 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
417     messages
418 schoenebeck 852 - added compile time options to allow disabling the various audio and
419     MIDI drivers
420 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
421     (patch by Ebrahim Mayat)
422 schoenebeck 697
423 persson 696 * Gigasampler format engine:
424 schoenebeck 738 - extensive synthesis optimization
425     (reimplementation of EGs and LFO(s), removed synthesis parameter
426     prerendering and the synthesis parameter matrix in general, splitting
427     each audio fragment into subfragments now where each subfragment uses
428 persson 830 constant pitch and filter coefficients. The volume coefficient is
429     linearly interpolated inside a subfragment, unless
430     --disable-interpolate-volume is set.)
431 persson 696 - fine tuning of the EG modulation parameters
432 persson 729 - improved filter cutoff calculation by adding support for the
433     following gig parameters: Cutoff freq (used when no cutoff
434     controller is defined), Control invert, Minimum cutoff, Velocity
435 persson 791 curve and Velocity range. The keyboard tracking now scales
436     cutoff frequency instead of resonance.
437 persson 877 - added support for gig parameter Resonance.
438 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
439 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
440     which can be overridden with --enable-global-attenuation
441 persson 783 - EG fixes: made the length of "attack hold" stage more
442     accurate. Release stage can now start before attack stage
443 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
444     time now has a minimal value to prevent clicks.
445 persson 799 - fixed pitch changes larger than one octave
446 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
447     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
448     all modes can be altered via standard GM messages, that is CC5 for
449     altering portamento time, CC65 for enabling / disabling portamento
450     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
451 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
452     parameter) and crossfade
453 persson 831 - added support for the "attenuation controller threshold" gig
454     parameter
455 persson 832 - added smoothing of volume changes caused by control change
456     messages
457 persson 865 - sample loop parameters are now taken from the DimensionRegion
458     instead of the wave chunk
459     - fixed keyswitching for v3 gigs with a number of keyswitch splits
460     not equal to a power of two
461 persson 877 - reimplementation of the filter algorithm. The new filter is more
462     accurate and supports all gig filter types, including bandreject
463     and lowpass turbo.
464 persson 903 - real support for 24 bit samples - samples are not truncated to
465     16 bits anymore
466     - support for aftertouch (channel pressure, not polyphonic
467     aftertouch)
468 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
469     amplifying from 0)
470 persson 696
471 schoenebeck 711 * LSCP server:
472     - fixed application exit on broken pipe error (fixes bug #20)
473 iliev 793 - fixed the notification messages delay due to lack of
474     network activity (fixes bug #26)
475 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
476     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
477 schoenebeck 711
478 schoenebeck 838 * audio driver:
479     - added aRts audio output driver (by no means RT safe)
480    
481 schoenebeck 775 * MIDI driver:
482     - fixed legacy sysex code which caused dispatching of MIDI SysEx
483     messages several times instead of once
484 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
485     for events (i.e. for offline rendering based MIDI drivers)
486 persson 922 - added checks for bad MIDI data
487 schoenebeck 775
488 schoenebeck 900 * linuxsampler application:
489     - show available sampler engine types on startup
490    
491 schoenebeck 705 * general changes:
492     - support for muting sampler channels and solo mode of the same, two new
493     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
494     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
495     introduced for this, the behavior is the same like on a mixer console
496 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
497     --enable-process-muted-channels which can be used to enable the
498     processing of muted channels.
499 iliev 777 - support for sostenuto pedal
500 iliev 779 - support for monitoring the total number of active voices
501 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
502     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
503 persson 835 - fixed some memory management errors
504 persson 841 - fixed some concurrency problems that could lead to crashes when
505     LSCP commands were executed
506 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
507     sampler channel (fixes bug #36)
508 schoenebeck 705
509 schoenebeck 692 Version 0.3.3 (15 July 2005)
510 schoenebeck 686
511     * packaging changes:
512     - fixed compilation with gcc 4.0
513    
514 schoenebeck 687 * Gigasampler format engine:
515     - LFO preprocessing was performed even though the respective LFO was
516     disabled by the instrument patch (minor efficiency fix)
517 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
518     for volume ramp downs in the same fragment (needed for current voice
519     stealing implementation) then simply inform the user with a warning
520     about possible click sounds and reduce the volume ramp down
521     appropriately instead of cancelling the audio device connection
522 schoenebeck 687
523 schoenebeck 677 Version 0.3.2 (24 June 2005)
524 schoenebeck 609
525     * packaging changes:
526     - updated autotools build files to compile on OS X
527     (conditional compilation of CoreMIDI and MidiShare drivers)
528 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
529     './configure --disable-asm' (definitely not recommended)
530 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
531     - require automake (>= 1.5) for 'make -f Makefile.cvs'
532     (due to 'dist-bzip2' automake option)
533 schoenebeck 649
534     * Gigasampler format engine:
535     - support for the gig parameters for "release velocity response" curves
536     - fine tuning of the EGADSR envelope
537     - volume of release triggered samples now depends on note-on velocity,
538     note length and gig parameter "release trigger decay" instead of
539     note-off velocity.
540 schoenebeck 663 - revised voice stealing
541     (fixes crash and endless loop caused by voice stealing)
542 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
543 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
544     instead of when the respective voice is actually launched
545     (fixes undefined behavior if stolen voices belonged to a key group -
546     this case was followed by a "killed voice survived" error message)
547 schoenebeck 669 - fixed minor issue with null/silence samples
548     (those stole voices even though they don't need a voice at all which
549     resulted in "voice stealing didn't work out" messages)
550 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
551     instrument or audio output device change
552 schoenebeck 654
553 schoenebeck 620 * LSCP server:
554 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
555 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
556 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
557 schoenebeck 609
558 schoenebeck 668 * linuxsampler application:
559     - added command line parameters --lscp-addr and --lscp-port to override
560     default IP address and port of LSCP server
561    
562 schoenebeck 579 Version 0.3.1 (24 May 2005)
563    
564     * initial release
