* fixed building with libgig installed in a non-standard directory

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