* bugfix: sometimes, when playing a note twice fast, the second note
  was silent

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 persson 1895 - minor fix in configure for mmsystem.h detection on MinGW
15 persson 1897 - Windows: look for editor plugins and Fantasia using base
16     directory of liblinuxsampler dll
17 persson 1899 - configure script fix: removed unconditional use of SSE
18 schoenebeck 1639
19 schoenebeck 1601 * general changes:
20     - bugfix: on some POSIX systems instrument editor plugins refused to
21     load as we used a non-portable Linux specific struct field
22     (fixes bug #70, patch by Ronald Baljeu)
23 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
24     plugin DLL on Windows systems failed
25 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded
26     - optimized the SynchronizedConfig class so it doesn't wait
27     unnecessarily long after an update
28 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
29     events (e.g. to highlight the pressed keys on the virtual keyboard
30     of gigedit)
31 schoenebeck 1659 - added support for triggering notes by instrument editors (see above)
32 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
33 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation
34     is only used by very few systems, most pick the int math
35     implementation, which is usually faster)
36 persson 1748 - fixes for audio drivers with varying buffer sizes
37 persson 1777 - experimental support for running LinuxSampler as a DSSI, LV2 and
38     VST plugin
39 iliev 1789 - notification events for stream/voice count statistics are now sent
40     only when there are actual changes
41 persson 1790 - added memory ordering constraints to improve stability on
42     multi-core and multi-cpu systems
43 schoenebeck 1800 - maximum voices and disk streams can now be altered at runtime
44 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
45 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
46     be switched on by command line option "--stacktrace" (the automatic
47     stacktrace mechanism seems to be broken on most systems at the moment)
48 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
49     a pointer to the launched InstrumentEditor object
50 schoenebeck 1876 - added optional 3rd party user data parameter for following
51     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
52     InstrumentEditor::Launch(),
53     InstrumentManager::LaunchInstrumentEditor()
54 persson 1887 - theoretical fix: made SynchronizedConfig follow C++0x memory
55     model more strictly
56 persson 1895 - fixes for using large audio device buffers
57 schoenebeck 1601
58 schoenebeck 1599 * audio driver:
59     - removed the nonsense audio channel constraint (which was hard coded to
60     max. 100 audio channels) for most audio drivers
61 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
62     opposed to the LSCP specs
63 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
64     reflected the wrong value
65 persson 1644 - fixed a memory management bug in ASIO driver
66 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used
67 persson 1777 - JACK: use jack_client_open instead of the deprecated
68 persson 1748 jack_client_new
69 iliev 1829 - added (experimental) CoreAudio driver
70 persson 1888 - applied old fixes to the ASIO driver that were included in the
71     previous binary release but accidentally never committed to CVS
72     (fixes #117)
73 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
74     win64)
75 persson 1895 - VST: added support for sample rate and buffer size changes
76     - VST: close editor (Fantasia) when the VST is removed
77 schoenebeck 1599
78 persson 1651 * MIDI driver:
79     - added JACK MIDI driver
80 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
81     want to (mis)use it for some purpose ("fixed" in all current MIDI
82     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
83 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
84 persson 1887 CoreMidi or AU
85 persson 1889 - fixed mingw-w64 compilation error in MME driver
86 persson 1651
87 schoenebeck 1604 * instruments database:
88 iliev 1603 - avoid time consuming samples scanning when adding instruments
89     to the instruments database
90 iliev 1727 - added support for handling lost files in the instruments database
91 iliev 1781 - Implemented option for adding instruments in separate directories
92     in the instruments database
93     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
94 iliev 1603
95 persson 1644 * Gigasampler format engine:
96     - fixed a memory leak that could happen when a channel was deleted
97     while notes were playing
98 persson 1646 - made it possible to load an instrument even if the audio thread
99     isn't running
100 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
101     enough for piano gigs with pedal noise samples
102 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
103     respective FX send MIDI controller was used
104 schoenebeck 1724 - added support for GM global device volume SysEx message
105 schoenebeck 1762 (can be selected at compile time to either apply globally to the
106     whole sampler [default] or only to the sampler channels that are
107     connected to the respective MIDI input port the SysEx message arrived
108     on)
109 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
110     sometimes wrongly killed in the same buffer, causing no sound to
111     be played
112 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
113     which is usally used to switch a part between chromatic sounds and
114     drumkit sounds (as opposed to their common default setting of MIDI
115     part 10 being a drumkit part and all other ones chromatic parts), in
116     LS however one can switch between the first 16 MIDI instrument maps
117     defined for the sampler
118 persson 1764 - made it possible to create multiple sample channels even if the
119     audio thread isn't running
120 persson 1844 - fixed crash when removing channel with active voices (#116)
121 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
122     un-cache the respective sample if it's really not used by any
123     sampler engine anymore
124     - re-cache samples in case they were changed by an instrument editor,
125     e.g. when a sample was added while playing (#82)
126 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
127     same time stamp as the voice's note-on event and occured both in the
128     same audio fragment cycle (fixes bug #112)
129 persson 1858 - added support for the "fine tune" and "pitch bend range"
130     instrument-level gig parameters
131     - fixed minor artifacts in pitch bend handling
132 schoenebeck 1860 - added support for GS Reset SysEx message
133 persson 1862 - allow gig files to use unlimited downward pitch shifting
134     - added a limit check for upward pitch shifting
135 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
136     note was silent
137 persson 1644
138 schoenebeck 1687 * LSCP server:
139     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
140     react on MIDI data arriving on certain sampler channels (so far only
141     Note-On and Note-Off events are sent via this LSCP event)
142 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
143     react on MIDI data arriving on certain MIDI input devices (so far only
144     Note-On and Note-Off events are sent via this LSCP event)
145 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
146     SET DB_INSTRUMENT FILE_PATH
147 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
148     frontends to send MIDI messages to specific sampler channel
149     - added two additional fields to GET FILE INSTRUMENT INFO command -
150     KEY_BINDINGS and KEYSWITCH_BINDINGS
151 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
152     was incorrect
153 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
154 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
155     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
156     be triggered respectively
157     - added new LSCP command "SET STREAMS" to globally alter the maximum
158     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
159     which will be triggered respectively
160 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
161     a gigedit file dialog is opened)
162 iliev 1848 - close all connections when LSCPServer is deleted
163 iliev 1882 - hard close of all sockets on exit
164 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
165     driver
166 schoenebeck 1687
167 iliev 1761 * Bug fixes:
168     - fixed a crash which occurs when removing a sampler channel waiting
169     to start instrument loading after another channel
170 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
171     instrument loading in progress (bug #113)
172 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
173     instrument with PERSISTENT load mode
174 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
175     - fixed memory leaks when issuing the following LSCP commands:
176     GET AUDIO_OUTPUT_DRIVER INFO
177     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
178     GET MIDI_INPUT_DRIVER INFO
179     GET MIDI_INPUT_DRIVER_PARAMETER INFO
180     - fixed possible compilation error when sqlite is not present
181 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
182 iliev 1847 - fixed crash when changing the audio output device of a sampler
183     channel with loaded instrument and start playing notes
184 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
185 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
186     PowerPC, which probably could cause crashes on that platform
187 persson 1889 - fixed a memory management error which could cause a crash when a
188     plugin was unloaded
189 persson 1896 - bugfix: two private structs had the same name, which could cause
190     problems if the linker chose the wrong constructor
191 iliev 1761
192    
193 schoenebeck 1560 Version 0.5.1 (6 December 2007)
194 schoenebeck 1454
195     * packaging changes:
196     - added autoconf checks for pthread library
197     - added autoconf check for pthread bug found on certain NPTL-enabled
198     glibc versions (see Gentoo bug report #194076)
199 senoner 1502 - added autoconf checks for MS Windows
200 schoenebeck 1454
201 persson 1455 * general changes:
202     - bugfix: the thread used by an editor plugin didn't die when the
203     editor closed
204 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
205     out all the space. operator--() did not apply size_mask after
206     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
207     order to avoid problems with the _NonVolatileReader functions.
208     - bugfix: Stream.h: added a missing divide by BytesPerSample in
209     GetWriteSpace(). Since this function is currently only used in
210     the stream's qsort() compare function, it didn't trigger any
211     bugs.
212     - Resampler.h, Synthesizer.h: cubic interpolation now works in
213     24bit mode too. Faster method to read 24bit words on little
214     endian machines (x86): replaced 3 byte reads + shifts with a 1
215     unaligned 32bit read and shift
216     - experimental support for MS Windows (MIDI input via MME, AUDIO
217     output via ASIO)
218     - made handling of SIGINT signal (Ctrl-C) a bit more robust
219 iliev 1541 - support for monitoring the total number of active disk streams
220     (new LSCP commands: GET TOTAL_STREAM_COUNT,
221     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
222 persson 1455
223 senoner 1500 * AUDIO driver:
224 persson 1534 - added Windows ASIO low latency audio driver
225 senoner 1500
226 senoner 1485 * MIDI driver:
227 schoenebeck 1495 - added MME Windows MIDI driver
228 senoner 1485
229 schoenebeck 1471 * LSCP server:
230     - added support for Windows style path / filenames, however with
231     forward slash path separators instead of backslash
232     (i.e. "C:/foo/bar.gig")
233 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
234     apostrophes as well
235 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
236     "LIST FILE INSTRUMENTS <file>" and
237     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
238     about an arbitrary instrument file on the system where the sampler is
239     running on
240 schoenebeck 1471
241 schoenebeck 1424 Version 0.5.0 (15 October 2007)
242 schoenebeck 947
243 schoenebeck 1065 * packaging changes:
244 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
245     API header files anymore
246 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
247     the Doxygen API documentation (explicitly listed in Doxyfile.in)
248 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
249     capable to execute our autoconf environment, thus no need anymore
250     to maintain the compile time configuration file (osx/version.h) for
251     OSX manually (patch by Toshi Nagata)
252 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
253     parameters
254 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
255     C++ API header files, all implementation internal global definitions
256     are now in global_private.h
257     - atomic.h is not exposed to the C++ API anymore
258     - no need to include config.h anymore for using LS's API header files
259     - fixed warnings in API doc generation
260 schoenebeck 1065
261 schoenebeck 947 * general changes:
262     - replaced the old, confusing MIDI program change mechanism by a
263     flexible MIDI instrument mapper which allows to map arbitrary
264 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
265 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
266     loaded on the respective channel when such MIDI program change
267     messages arrive, beside that, each entry allows to define a life-time
268     strategy for the instrument, so the user can define whether the
269     instrument should i.e. be permanently loaded (to be able to switch
270     quickly among sounds) or i.e. loaded just on demand when the
271     respective program change arrives (to safe RAM space), as well as a
272     global volume factor for each entry, so the user can adjust the volume
273     dynamic of his mapped instrument collection without having to modify
274 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
275     MIDI instrument maps and assign each sampler channel individually
276     a certain map, so that i.e. separation of normal instruments and
277     drumkits is possible
278 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
279     MIDI instrument maps, MIDI instruments, FX sends, global volume.
280 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
281     due to a constant size RingBuffer FIFO which is now replaced by a
282     dynamic (unlimited) size std::list FIFO
283 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
284     output channels for being processed by external effect processors
285     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
286     controllers
287 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
288 iliev 1130 - Implemented new, improved notification system
289 schoenebeck 1149 - fixed compilation errors regarding OSX
290     (patch by Toshi Nagata)
291 iliev 1161 - implemented instruments database
292 iliev 1345 - added support for escape sequences to the instruments database
293 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
294     within the sampler's process (by using instrument editor plugins),
295     you'll notice the new "Registered instrument editors:" message on
296 schoenebeck 1407 startup, added a new LSCP command:
297     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
298 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
299     given sampler channel, the plugin path can be overridden at compile
300     time with ./configure --enable-plugin-dir=/some/dir
301 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
302     in the sampler's process to safely edit instruments while playing
303     without a crash (hopefully) by either suspending single regions
304     wherever possible or if unavoidable whole engine(s)
305 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
306     policy and priority on thread level, set a minimum stack size for
307     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
308     threads simply inherited properties of starting thread instead of
309     setting their own policy and priority
310 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
311     main process did not wait for the stack trace process to finish
312     its output
313 persson 1248 - fixed some minor memory leaks
314 schoenebeck 1259 - reenabled assembly features support, at the moment only for
315     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
316 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
317     register, to avoid relocations in the text segment at runtime)
318 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
319 schoenebeck 947
320     * MIDI driver:
321     - dispatch bank select (MSB and LSB) messages
322    
323 schoenebeck 1049 * audio driver:
324     - the ALSA audio output driver parameters now reflect the correct
325     parameter value ranges for the respective selected sound card
326     (patch by Till Wimmer, a bit fixed and extended)
327    
328 persson 951 * Gigasampler format engine:
329     - if a filter is used and EG2 finishes before EG1, let the voice
330     die when EG2 has finished (this fixes a problem with clicks and
331     voice starvation for some gigs)
332 persson 1038 - playback is no longer disabled during instrument loading
333     - all notes playing on a channel that changes its instrument keep
334     playing with the old instrument until they get a note off
335     command
336 persson 1039 - EG fix: a release value of zero could cause noises or crash
337 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
338 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
339     above max sustain level, which means that there is a decay phase
340     even if sustain is 100%
341 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
342     noises or crashes
343 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
344 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
345     supplied to the configure script (fixes #46)
346 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
347     instead of a fix value
348 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
349     127 (solo mode) only kill voices if the respective mode really
350     changed
351 persson 951
352 schoenebeck 1244 * LSCP server:
353     - fixed compile time error for old Bison versions
354     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
355 schoenebeck 1245 - parser now supports extended ASCII character set
356     (up to ASCII code 255, i.e. includes now umlauts and accents)
357     - filename arguments in LSCP commands now allow to use escape
358     sequences, that is directly literal as one of: \', \", \\, \n, \r,
359     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
360     code value like \xf2) (fixes bug #24)
361 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
362     least one of their text-based parameters (i.e. name, description):
363     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
364     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
365     "SET DB_INSTRUMENT_DIRECTORY NAME",
366     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
367     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
368     "FIND DB_INSTRUMENT_DIRECTORIES"
369 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
370     occured, the unexpected character and the actually expected, possible
371     character(s), the latter only if less than 5 possibilities)
372 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
373     settings
374 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
375     of strings were treated as being one string containing commas
376     (fixes #57)
377 schoenebeck 1244
378 iliev 959 * Bug fixes:
379     - fixed crash occurring on certain LSCP scripts (Bug 39)
380 persson 1038 - another thread safety fix for lscp "load engine" and "set
381     channel audio output device"
382 iliev 1283 - fixed a crash which occurs when reassigning the same engine
383     on a sampler channel with connected MIDI device
384 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
385     device connected to a sampler channel to number less then or equal
386     to the index of the port to which the sampler channel is connected.
387 iliev 1296 - The previous bindings were not been disconnected when altering
388     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
389     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
390 iliev 1297 - The active stream/voice count statistic was incorrect.
391 iliev 1298 - notification events were not been sent for some sampler
392     channel changes
393 iliev 1305 - added default min and max values to restrict the number of allowed
394     audio output channels and MIDI input ports
395 iliev 1306 - the connection to the PCM interface is now closed when destroying
396     an audio output device
397 schoenebeck 1332 - files with slash in their path or filename could not be loaded
398 iliev 959
399 schoenebeck 1221 * test cases:
400     - updated and fixed (haven't been touched in a while)
401    
402 schoenebeck 937 Version 0.4.0 (24 November 2006)
403 persson 696
404 schoenebeck 697 * packaging changes:
405 capela 868 - changed deprecated copyright attribute to license; added ldconfig
406     to post-(un)install steps; added devel package for liblinuxsampler;
407     to linuxsampler.spec (RPM)
408 schoenebeck 697 - install necessary development header files for allowing 3rd party
409     applications to link against liblinuxsampler
410     - liblinuxsampler's API documentation can be generated with 'make docs'
411     (Doxygen required)
412 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
413     implementation (currently either an integer math solution or a
414     di-harmonic approximation), automatic detection can be overriden
415     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
416     configure script argument though (mandatory for cross-compilation)
417 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
418     provided some on his own (as CXXFLAGS)
419 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
420     messages
421 schoenebeck 852 - added compile time options to allow disabling the various audio and
422     MIDI drivers
423 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
424     (patch by Ebrahim Mayat)
425 schoenebeck 697
426 persson 696 * Gigasampler format engine:
427 schoenebeck 738 - extensive synthesis optimization
428     (reimplementation of EGs and LFO(s), removed synthesis parameter
429     prerendering and the synthesis parameter matrix in general, splitting
430     each audio fragment into subfragments now where each subfragment uses
431 persson 830 constant pitch and filter coefficients. The volume coefficient is
432     linearly interpolated inside a subfragment, unless
433     --disable-interpolate-volume is set.)
434 persson 696 - fine tuning of the EG modulation parameters
435 persson 729 - improved filter cutoff calculation by adding support for the
436     following gig parameters: Cutoff freq (used when no cutoff
437     controller is defined), Control invert, Minimum cutoff, Velocity
438 persson 791 curve and Velocity range. The keyboard tracking now scales
439     cutoff frequency instead of resonance.
440 persson 877 - added support for gig parameter Resonance.
441 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
442 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
443     which can be overridden with --enable-global-attenuation
444 persson 783 - EG fixes: made the length of "attack hold" stage more
445     accurate. Release stage can now start before attack stage
446 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
447     time now has a minimal value to prevent clicks.
448 persson 799 - fixed pitch changes larger than one octave
449 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
450     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
451     all modes can be altered via standard GM messages, that is CC5 for
452     altering portamento time, CC65 for enabling / disabling portamento
453     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
454 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
455     parameter) and crossfade
456 persson 831 - added support for the "attenuation controller threshold" gig
457     parameter
458 persson 832 - added smoothing of volume changes caused by control change
459     messages
460 persson 865 - sample loop parameters are now taken from the DimensionRegion
461     instead of the wave chunk
462     - fixed keyswitching for v3 gigs with a number of keyswitch splits
463     not equal to a power of two
464 persson 877 - reimplementation of the filter algorithm. The new filter is more
465     accurate and supports all gig filter types, including bandreject
466     and lowpass turbo.
467 persson 903 - real support for 24 bit samples - samples are not truncated to
468     16 bits anymore
469     - support for aftertouch (channel pressure, not polyphonic
470     aftertouch)
471 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
472     amplifying from 0)
473 persson 696
474 schoenebeck 711 * LSCP server:
475     - fixed application exit on broken pipe error (fixes bug #20)
476 iliev 793 - fixed the notification messages delay due to lack of
477     network activity (fixes bug #26)
478 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
479     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
480 schoenebeck 711
481 schoenebeck 838 * audio driver:
482     - added aRts audio output driver (by no means RT safe)
483    
484 schoenebeck 775 * MIDI driver:
485     - fixed legacy sysex code which caused dispatching of MIDI SysEx
486     messages several times instead of once
487 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
488     for events (i.e. for offline rendering based MIDI drivers)
489 persson 922 - added checks for bad MIDI data
490 schoenebeck 775
491 schoenebeck 900 * linuxsampler application:
492     - show available sampler engine types on startup
493    
494 schoenebeck 705 * general changes:
495     - support for muting sampler channels and solo mode of the same, two new
496     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
497     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
498     introduced for this, the behavior is the same like on a mixer console
499 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
500     --enable-process-muted-channels which can be used to enable the
501     processing of muted channels.
502 iliev 777 - support for sostenuto pedal
503 iliev 779 - support for monitoring the total number of active voices
504 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
505     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
506 persson 835 - fixed some memory management errors
507 persson 841 - fixed some concurrency problems that could lead to crashes when
508     LSCP commands were executed
509 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
510     sampler channel (fixes bug #36)
511 schoenebeck 705
512 schoenebeck 692 Version 0.3.3 (15 July 2005)
513 schoenebeck 686
514     * packaging changes:
515     - fixed compilation with gcc 4.0
516    
517 schoenebeck 687 * Gigasampler format engine:
518     - LFO preprocessing was performed even though the respective LFO was
519     disabled by the instrument patch (minor efficiency fix)
520 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
521     for volume ramp downs in the same fragment (needed for current voice
522     stealing implementation) then simply inform the user with a warning
523     about possible click sounds and reduce the volume ramp down
524     appropriately instead of cancelling the audio device connection
525 schoenebeck 687
526 schoenebeck 677 Version 0.3.2 (24 June 2005)
527 schoenebeck 609
528     * packaging changes:
529     - updated autotools build files to compile on OS X
530     (conditional compilation of CoreMIDI and MidiShare drivers)
531 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
532     './configure --disable-asm' (definitely not recommended)
533 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
534     - require automake (>= 1.5) for 'make -f Makefile.cvs'
535     (due to 'dist-bzip2' automake option)
536 schoenebeck 649
537     * Gigasampler format engine:
538     - support for the gig parameters for "release velocity response" curves
539     - fine tuning of the EGADSR envelope
540     - volume of release triggered samples now depends on note-on velocity,
541     note length and gig parameter "release trigger decay" instead of
542     note-off velocity.
543 schoenebeck 663 - revised voice stealing
544     (fixes crash and endless loop caused by voice stealing)
545 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
546 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
547     instead of when the respective voice is actually launched
548     (fixes undefined behavior if stolen voices belonged to a key group -
549     this case was followed by a "killed voice survived" error message)
550 schoenebeck 669 - fixed minor issue with null/silence samples
551     (those stole voices even though they don't need a voice at all which
552     resulted in "voice stealing didn't work out" messages)
553 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
554     instrument or audio output device change
555 schoenebeck 654
556 schoenebeck 620 * LSCP server:
557 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
558 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
559 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
560 schoenebeck 609
561 schoenebeck 668 * linuxsampler application:
562     - added command line parameters --lscp-addr and --lscp-port to override
563     default IP address and port of LSCP server
564    
565 schoenebeck 579 Version 0.3.1 (24 May 2005)
566    
567     * initial release
