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