* fixed endless loop in Engine::SuspendAll() (bug #120)
* AU plugin, work in progress: minor fixes in the build files

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