* fixed orphaned pointers when setting maximum voices limit (bug #118)

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