File size: 27144 byte(s)
* fixed hanging notes which occured when note-off event had the exact
  same time stamp as the voice's note-on event and occured both in the
  same audio fragment cycle (fixes bug #112)
* bumped version to 0.5.1.11cvs

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