* added support for GS Reset SysEx message

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