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