* LSCP server: hard close of all sockets on exit
* Load instruments in background when restoring plugin state

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 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
45     a pointer to the launched InstrumentEditor object
46 schoenebeck 1876 - added optional 3rd party user data parameter for following
47     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
48     InstrumentEditor::Launch(),
49     InstrumentManager::LaunchInstrumentEditor()
50 schoenebeck 1601
51 schoenebeck 1599 * audio driver:
52     - removed the nonsense audio channel constraint (which was hard coded to
53     max. 100 audio channels) for most audio drivers
54 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
55     opposed to the LSCP specs
56 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
57     reflected the wrong value
58 persson 1644 - fixed a memory management bug in ASIO driver
59 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used
60 persson 1777 - JACK: use jack_client_open instead of the deprecated
61 persson 1748 jack_client_new
62 iliev 1829 - added (experimental) CoreAudio driver
63 schoenebeck 1599
64 persson 1651 * MIDI driver:
65     - added JACK MIDI driver
66 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
67     want to (mis)use it for some purpose ("fixed" in all current MIDI
68     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
69 persson 1651
70 schoenebeck 1604 * instruments database:
71 iliev 1603 - avoid time consuming samples scanning when adding instruments
72     to the instruments database
73 iliev 1727 - added support for handling lost files in the instruments database
74 iliev 1781 - Implemented option for adding instruments in separate directories
75     in the instruments database
76     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
77 iliev 1603
78 persson 1644 * Gigasampler format engine:
79     - fixed a memory leak that could happen when a channel was deleted
80     while notes were playing
81 persson 1646 - made it possible to load an instrument even if the audio thread
82     isn't running
83 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
84     enough for piano gigs with pedal noise samples
85 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
86     respective FX send MIDI controller was used
87 schoenebeck 1724 - added support for GM global device volume SysEx message
88 schoenebeck 1762 (can be selected at compile time to either apply globally to the
89     whole sampler [default] or only to the sampler channels that are
90     connected to the respective MIDI input port the SysEx message arrived
91     on)
92 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
93     sometimes wrongly killed in the same buffer, causing no sound to
94     be played
95 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
96     which is usally used to switch a part between chromatic sounds and
97     drumkit sounds (as opposed to their common default setting of MIDI
98     part 10 being a drumkit part and all other ones chromatic parts), in
99     LS however one can switch between the first 16 MIDI instrument maps
100     defined for the sampler
101 persson 1764 - made it possible to create multiple sample channels even if the
102     audio thread isn't running
103 persson 1844 - fixed crash when removing channel with active voices (#116)
104 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
105     un-cache the respective sample if it's really not used by any
106     sampler engine anymore
107     - re-cache samples in case they were changed by an instrument editor,
108     e.g. when a sample was added while playing (#82)
109 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
110     same time stamp as the voice's note-on event and occured both in the
111     same audio fragment cycle (fixes bug #112)
112 persson 1858 - added support for the "fine tune" and "pitch bend range"
113     instrument-level gig parameters
114     - fixed minor artifacts in pitch bend handling
115 schoenebeck 1860 - added support for GS Reset SysEx message
116 persson 1862 - allow gig files to use unlimited downward pitch shifting
117     - added a limit check for upward pitch shifting
118 persson 1644
119 schoenebeck 1687 * LSCP server:
120     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
121     react on MIDI data arriving on certain sampler channels (so far only
122     Note-On and Note-Off events are sent via this LSCP event)
123 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
124     react on MIDI data arriving on certain MIDI input devices (so far only
125     Note-On and Note-Off events are sent via this LSCP event)
126 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
127     SET DB_INSTRUMENT FILE_PATH
128 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
129     frontends to send MIDI messages to specific sampler channel
130     - added two additional fields to GET FILE INSTRUMENT INFO command -
131     KEY_BINDINGS and KEYSWITCH_BINDINGS
132 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
133     was incorrect
134 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
135 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
136     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
137     be triggered respectively
138     - added new LSCP command "SET STREAMS" to globally alter the maximum
139     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
140     which will be triggered respectively
141 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
142     a gigedit file dialog is opened)
143 iliev 1848 - close all connections when LSCPServer is deleted
144 iliev 1882 - hard close of all sockets on exit
145 schoenebeck 1687
146 iliev 1761 * Bug fixes:
147     - fixed a crash which occurs when removing a sampler channel waiting
148     to start instrument loading after another channel
149 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
150     instrument loading in progress (bug #113)
151 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
152     instrument with PERSISTENT load mode
153 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
154     - fixed memory leaks when issuing the following LSCP commands:
155     GET AUDIO_OUTPUT_DRIVER INFO
156     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
157     GET MIDI_INPUT_DRIVER INFO
158     GET MIDI_INPUT_DRIVER_PARAMETER INFO
159     - fixed possible compilation error when sqlite is not present
160 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
161 iliev 1847 - fixed crash when changing the audio output device of a sampler
162     channel with loaded instrument and start playing notes
163 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
164 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
165     PowerPC, which probably could cause crashes on that platform
166 iliev 1761
167    
168 schoenebeck 1560 Version 0.5.1 (6 December 2007)
169 schoenebeck 1454
170     * packaging changes:
171     - added autoconf checks for pthread library
172     - added autoconf check for pthread bug found on certain NPTL-enabled
173     glibc versions (see Gentoo bug report #194076)
174 senoner 1502 - added autoconf checks for MS Windows
175 schoenebeck 1454
176 persson 1455 * general changes:
177     - bugfix: the thread used by an editor plugin didn't die when the
178     editor closed
179 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
180     out all the space. operator--() did not apply size_mask after
181     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
182     order to avoid problems with the _NonVolatileReader functions.
183     - bugfix: Stream.h: added a missing divide by BytesPerSample in
184     GetWriteSpace(). Since this function is currently only used in
185     the stream's qsort() compare function, it didn't trigger any
186     bugs.
187     - Resampler.h, Synthesizer.h: cubic interpolation now works in
188     24bit mode too. Faster method to read 24bit words on little
189     endian machines (x86): replaced 3 byte reads + shifts with a 1
190     unaligned 32bit read and shift
191     - experimental support for MS Windows (MIDI input via MME, AUDIO
192     output via ASIO)
193     - made handling of SIGINT signal (Ctrl-C) a bit more robust
194 iliev 1541 - support for monitoring the total number of active disk streams
195     (new LSCP commands: GET TOTAL_STREAM_COUNT,
196     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
197 persson 1455
198 senoner 1500 * AUDIO driver:
199 persson 1534 - added Windows ASIO low latency audio driver
200 senoner 1500
201 senoner 1485 * MIDI driver:
202 schoenebeck 1495 - added MME Windows MIDI driver
203 senoner 1485
204 schoenebeck 1471 * LSCP server:
205     - added support for Windows style path / filenames, however with
206     forward slash path separators instead of backslash
207     (i.e. "C:/foo/bar.gig")
208 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
209     apostrophes as well
210 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
211     "LIST FILE INSTRUMENTS <file>" and
212     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
213     about an arbitrary instrument file on the system where the sampler is
214     running on
215 schoenebeck 1471
216 schoenebeck 1424 Version 0.5.0 (15 October 2007)
217 schoenebeck 947
218 schoenebeck 1065 * packaging changes:
219 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
220     API header files anymore
221 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
222     the Doxygen API documentation (explicitly listed in Doxyfile.in)
223 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
224     capable to execute our autoconf environment, thus no need anymore
225     to maintain the compile time configuration file (osx/version.h) for
226     OSX manually (patch by Toshi Nagata)
227 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
228     parameters
229 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
230     C++ API header files, all implementation internal global definitions
231     are now in global_private.h
232     - atomic.h is not exposed to the C++ API anymore
233     - no need to include config.h anymore for using LS's API header files
234     - fixed warnings in API doc generation
235 schoenebeck 1065
236 schoenebeck 947 * general changes:
237     - replaced the old, confusing MIDI program change mechanism by a
238     flexible MIDI instrument mapper which allows to map arbitrary
239 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
240 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
241     loaded on the respective channel when such MIDI program change
242     messages arrive, beside that, each entry allows to define a life-time
243     strategy for the instrument, so the user can define whether the
244     instrument should i.e. be permanently loaded (to be able to switch
245     quickly among sounds) or i.e. loaded just on demand when the
246     respective program change arrives (to safe RAM space), as well as a
247     global volume factor for each entry, so the user can adjust the volume
248     dynamic of his mapped instrument collection without having to modify
249 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
250     MIDI instrument maps and assign each sampler channel individually
251     a certain map, so that i.e. separation of normal instruments and
252     drumkits is possible
253 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
254     MIDI instrument maps, MIDI instruments, FX sends, global volume.
255 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
256     due to a constant size RingBuffer FIFO which is now replaced by a
257     dynamic (unlimited) size std::list FIFO
258 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
259     output channels for being processed by external effect processors
260     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
261     controllers
262 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
263 iliev 1130 - Implemented new, improved notification system
264 schoenebeck 1149 - fixed compilation errors regarding OSX
265     (patch by Toshi Nagata)
266 iliev 1161 - implemented instruments database
267 iliev 1345 - added support for escape sequences to the instruments database
268 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
269     within the sampler's process (by using instrument editor plugins),
270     you'll notice the new "Registered instrument editors:" message on
271 schoenebeck 1407 startup, added a new LSCP command:
272     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
273 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
274     given sampler channel, the plugin path can be overridden at compile
275     time with ./configure --enable-plugin-dir=/some/dir
276 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
277     in the sampler's process to safely edit instruments while playing
278     without a crash (hopefully) by either suspending single regions
279     wherever possible or if unavoidable whole engine(s)
280 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
281     policy and priority on thread level, set a minimum stack size for
282     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
283     threads simply inherited properties of starting thread instead of
284     setting their own policy and priority
285 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
286     main process did not wait for the stack trace process to finish
287     its output
288 persson 1248 - fixed some minor memory leaks
289 schoenebeck 1259 - reenabled assembly features support, at the moment only for
290     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
291 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
292     register, to avoid relocations in the text segment at runtime)
293 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
294 schoenebeck 947
295     * MIDI driver:
296     - dispatch bank select (MSB and LSB) messages
297    
298 schoenebeck 1049 * audio driver:
299     - the ALSA audio output driver parameters now reflect the correct
300     parameter value ranges for the respective selected sound card
301     (patch by Till Wimmer, a bit fixed and extended)
302    
303 persson 951 * Gigasampler format engine:
304     - if a filter is used and EG2 finishes before EG1, let the voice
305     die when EG2 has finished (this fixes a problem with clicks and
306     voice starvation for some gigs)
307 persson 1038 - playback is no longer disabled during instrument loading
308     - all notes playing on a channel that changes its instrument keep
309     playing with the old instrument until they get a note off
310     command
311 persson 1039 - EG fix: a release value of zero could cause noises or crash
312 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
313 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
314     above max sustain level, which means that there is a decay phase
315     even if sustain is 100%
316 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
317     noises or crashes
318 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
319 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
320     supplied to the configure script (fixes #46)
321 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
322     instead of a fix value
323 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
324     127 (solo mode) only kill voices if the respective mode really
325     changed
326 persson 951
327 schoenebeck 1244 * LSCP server:
328     - fixed compile time error for old Bison versions
329     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
330 schoenebeck 1245 - parser now supports extended ASCII character set
331     (up to ASCII code 255, i.e. includes now umlauts and accents)
332     - filename arguments in LSCP commands now allow to use escape
333     sequences, that is directly literal as one of: \', \", \\, \n, \r,
334     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
335     code value like \xf2) (fixes bug #24)
336 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
337     least one of their text-based parameters (i.e. name, description):
338     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
339     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
340     "SET DB_INSTRUMENT_DIRECTORY NAME",
341     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
342     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
343     "FIND DB_INSTRUMENT_DIRECTORIES"
344 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
345     occured, the unexpected character and the actually expected, possible
346     character(s), the latter only if less than 5 possibilities)
347 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
348     settings
349 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
350     of strings were treated as being one string containing commas
351     (fixes #57)
352 schoenebeck 1244
353 iliev 959 * Bug fixes:
354     - fixed crash occurring on certain LSCP scripts (Bug 39)
355 persson 1038 - another thread safety fix for lscp "load engine" and "set
356     channel audio output device"
357 iliev 1283 - fixed a crash which occurs when reassigning the same engine
358     on a sampler channel with connected MIDI device
359 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
360     device connected to a sampler channel to number less then or equal
361     to the index of the port to which the sampler channel is connected.
362 iliev 1296 - The previous bindings were not been disconnected when altering
363     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
364     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
365 iliev 1297 - The active stream/voice count statistic was incorrect.
366 iliev 1298 - notification events were not been sent for some sampler
367     channel changes
368 iliev 1305 - added default min and max values to restrict the number of allowed
369     audio output channels and MIDI input ports
370 iliev 1306 - the connection to the PCM interface is now closed when destroying
371     an audio output device
372 schoenebeck 1332 - files with slash in their path or filename could not be loaded
373 iliev 959
374 schoenebeck 1221 * test cases:
375     - updated and fixed (haven't been touched in a while)
376    
377 schoenebeck 937 Version 0.4.0 (24 November 2006)
378 persson 696
379 schoenebeck 697 * packaging changes:
380 capela 868 - changed deprecated copyright attribute to license; added ldconfig
381     to post-(un)install steps; added devel package for liblinuxsampler;
382     to linuxsampler.spec (RPM)
383 schoenebeck 697 - install necessary development header files for allowing 3rd party
384     applications to link against liblinuxsampler
385     - liblinuxsampler's API documentation can be generated with 'make docs'
386     (Doxygen required)
387 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
388     implementation (currently either an integer math solution or a
389     di-harmonic approximation), automatic detection can be overriden
390     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
391     configure script argument though (mandatory for cross-compilation)
392 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
393     provided some on his own (as CXXFLAGS)
394 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
395     messages
396 schoenebeck 852 - added compile time options to allow disabling the various audio and
397     MIDI drivers
398 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
399     (patch by Ebrahim Mayat)
400 schoenebeck 697
401 persson 696 * Gigasampler format engine:
402 schoenebeck 738 - extensive synthesis optimization
403     (reimplementation of EGs and LFO(s), removed synthesis parameter
404     prerendering and the synthesis parameter matrix in general, splitting
405     each audio fragment into subfragments now where each subfragment uses
406 persson 830 constant pitch and filter coefficients. The volume coefficient is
407     linearly interpolated inside a subfragment, unless
408     --disable-interpolate-volume is set.)
409 persson 696 - fine tuning of the EG modulation parameters
410 persson 729 - improved filter cutoff calculation by adding support for the
411     following gig parameters: Cutoff freq (used when no cutoff
412     controller is defined), Control invert, Minimum cutoff, Velocity
413 persson 791 curve and Velocity range. The keyboard tracking now scales
414     cutoff frequency instead of resonance.
415 persson 877 - added support for gig parameter Resonance.
416 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
417 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
418     which can be overridden with --enable-global-attenuation
419 persson 783 - EG fixes: made the length of "attack hold" stage more
420     accurate. Release stage can now start before attack stage
421 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
422     time now has a minimal value to prevent clicks.
423 persson 799 - fixed pitch changes larger than one octave
424 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
425     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
426     all modes can be altered via standard GM messages, that is CC5 for
427     altering portamento time, CC65 for enabling / disabling portamento
428     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
429 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
430     parameter) and crossfade
431 persson 831 - added support for the "attenuation controller threshold" gig
432     parameter
433 persson 832 - added smoothing of volume changes caused by control change
434     messages
435 persson 865 - sample loop parameters are now taken from the DimensionRegion
436     instead of the wave chunk
437     - fixed keyswitching for v3 gigs with a number of keyswitch splits
438     not equal to a power of two
439 persson 877 - reimplementation of the filter algorithm. The new filter is more
440     accurate and supports all gig filter types, including bandreject
441     and lowpass turbo.
442 persson 903 - real support for 24 bit samples - samples are not truncated to
443     16 bits anymore
444     - support for aftertouch (channel pressure, not polyphonic
445     aftertouch)
446 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
447     amplifying from 0)
448 persson 696
449 schoenebeck 711 * LSCP server:
450     - fixed application exit on broken pipe error (fixes bug #20)
451 iliev 793 - fixed the notification messages delay due to lack of
452     network activity (fixes bug #26)
453 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
454     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
455 schoenebeck 711
456 schoenebeck 838 * audio driver:
457     - added aRts audio output driver (by no means RT safe)
458    
459 schoenebeck 775 * MIDI driver:
460     - fixed legacy sysex code which caused dispatching of MIDI SysEx
461     messages several times instead of once
462 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
463     for events (i.e. for offline rendering based MIDI drivers)
464 persson 922 - added checks for bad MIDI data
465 schoenebeck 775
466 schoenebeck 900 * linuxsampler application:
467     - show available sampler engine types on startup
468    
469 schoenebeck 705 * general changes:
470     - support for muting sampler channels and solo mode of the same, two new
471     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
472     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
473     introduced for this, the behavior is the same like on a mixer console
474 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
475     --enable-process-muted-channels which can be used to enable the
476     processing of muted channels.
477 iliev 777 - support for sostenuto pedal
478 iliev 779 - support for monitoring the total number of active voices
479 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
480     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
481 persson 835 - fixed some memory management errors
482 persson 841 - fixed some concurrency problems that could lead to crashes when
483     LSCP commands were executed
484 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
485     sampler channel (fixes bug #36)
486 schoenebeck 705
487 schoenebeck 692 Version 0.3.3 (15 July 2005)
488 schoenebeck 686
489     * packaging changes:
490     - fixed compilation with gcc 4.0
491    
492 schoenebeck 687 * Gigasampler format engine:
493     - LFO preprocessing was performed even though the respective LFO was
494     disabled by the instrument patch (minor efficiency fix)
495 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
496     for volume ramp downs in the same fragment (needed for current voice
497     stealing implementation) then simply inform the user with a warning
498     about possible click sounds and reduce the volume ramp down
499     appropriately instead of cancelling the audio device connection
500 schoenebeck 687
501 schoenebeck 677 Version 0.3.2 (24 June 2005)
502 schoenebeck 609
503     * packaging changes:
504     - updated autotools build files to compile on OS X
505     (conditional compilation of CoreMIDI and MidiShare drivers)
506 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
507     './configure --disable-asm' (definitely not recommended)
508 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
509     - require automake (>= 1.5) for 'make -f Makefile.cvs'
510     (due to 'dist-bzip2' automake option)
511 schoenebeck 649
512     * Gigasampler format engine:
513     - support for the gig parameters for "release velocity response" curves
514     - fine tuning of the EGADSR envelope
515     - volume of release triggered samples now depends on note-on velocity,
516     note length and gig parameter "release trigger decay" instead of
517     note-off velocity.
518 schoenebeck 663 - revised voice stealing
519     (fixes crash and endless loop caused by voice stealing)
520 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
521 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
522     instead of when the respective voice is actually launched
523     (fixes undefined behavior if stolen voices belonged to a key group -
524     this case was followed by a "killed voice survived" error message)
525 schoenebeck 669 - fixed minor issue with null/silence samples
526     (those stole voices even though they don't need a voice at all which
527     resulted in "voice stealing didn't work out" messages)
528 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
529     instrument or audio output device change
530 schoenebeck 654
531 schoenebeck 620 * LSCP server:
532 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
533 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
534 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
535 schoenebeck 609
536 schoenebeck 668 * linuxsampler application:
537     - added command line parameters --lscp-addr and --lscp-port to override
538     default IP address and port of LSCP server
539    
540 schoenebeck 579 Version 0.3.1 (24 May 2005)
541    
542     * initial release
