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 persson 1908 - VST: avoid opening Fantasia more than once for each VST instance
78     - VST: export main function as "main" on Linux too (fix for
79     energyXT)
80 schoenebeck 1599
81 persson 1651 * MIDI driver:
82     - added JACK MIDI driver
83 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
84     want to (mis)use it for some purpose ("fixed" in all current MIDI
85     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
86 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
87 persson 1887 CoreMidi or AU
88 persson 1889 - fixed mingw-w64 compilation error in MME driver
89 persson 1651
90 schoenebeck 1604 * instruments database:
91 iliev 1603 - avoid time consuming samples scanning when adding instruments
92     to the instruments database
93 iliev 1727 - added support for handling lost files in the instruments database

97 persson 1908 - work-around for missing fnmatch function on Windows to make
98     instrument database compilable
99 iliev 1603
100 persson 1644 * Gigasampler format engine:
101     - fixed a memory leak that could happen when a channel was deleted
102     while notes were playing
103 persson 1646 - made it possible to load an instrument even if the audio thread
104     isn't running
105 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
106     enough for piano gigs with pedal noise samples
107 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
108     respective FX send MIDI controller was used
109 schoenebeck 1724 - added support for GM global device volume SysEx message
110 schoenebeck 1762 (can be selected at compile time to either apply globally to the
111     whole sampler [default] or only to the sampler channels that are
112     connected to the respective MIDI input port the SysEx message arrived
113     on)
114 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
115     sometimes wrongly killed in the same buffer, causing no sound to
116     be played
117 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
118     which is usally used to switch a part between chromatic sounds and
119     drumkit sounds (as opposed to their common default setting of MIDI
120     part 10 being a drumkit part and all other ones chromatic parts), in
121     LS however one can switch between the first 16 MIDI instrument maps
122     defined for the sampler
123 persson 1764 - made it possible to create multiple sample channels even if the
124     audio thread isn't running
125 persson 1844 - fixed crash when removing channel with active voices (#116)
126 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
127     un-cache the respective sample if it's really not used by any
128     sampler engine anymore
129     - re-cache samples in case they were changed by an instrument editor,
130     e.g. when a sample was added while playing (#82)
131 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
132     same time stamp as the voice's note-on event and occured both in the
133     same audio fragment cycle (fixes bug #112)
134 persson 1858 - added support for the "fine tune" and "pitch bend range"
135     instrument-level gig parameters
136     - fixed minor artifacts in pitch bend handling
137 schoenebeck 1860 - added support for GS Reset SysEx message
138 persson 1862 - allow gig files to use unlimited downward pitch shifting
139     - added a limit check for upward pitch shifting
140 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
141     note was silent
142 persson 1644
143 schoenebeck 1687 * LSCP server:
144     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
145     react on MIDI data arriving on certain sampler channels (so far only
146     Note-On and Note-Off events are sent via this LSCP event)
147 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
148     react on MIDI data arriving on certain MIDI input devices (so far only
149     Note-On and Note-Off events are sent via this LSCP event)
150 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
151     SET DB_INSTRUMENT FILE_PATH
152 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
153     frontends to send MIDI messages to specific sampler channel
154     - added two additional fields to GET FILE INSTRUMENT INFO command -
155     KEY_BINDINGS and KEYSWITCH_BINDINGS
156 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
157     was incorrect
158 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
159 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
160     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
161     be triggered respectively
162     - added new LSCP command "SET STREAMS" to globally alter the maximum
163     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
164     which will be triggered respectively
165 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
166     a gigedit file dialog is opened)
167 iliev 1848 - close all connections when LSCPServer is deleted
168 iliev 1882 - hard close of all sockets on exit
169 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
170     driver
171 schoenebeck 1687
172 iliev 1761 * Bug fixes:
173     - fixed a crash which occurs when removing a sampler channel waiting
174     to start instrument loading after another channel
175 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
176     instrument loading in progress (bug #113)
177 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
178     instrument with PERSISTENT load mode
179 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
180     - fixed memory leaks when issuing the following LSCP commands:
181     GET AUDIO_OUTPUT_DRIVER INFO
182     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
183     GET MIDI_INPUT_DRIVER INFO
184     GET MIDI_INPUT_DRIVER_PARAMETER INFO
185     - fixed possible compilation error when sqlite is not present
186 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
187 iliev 1847 - fixed crash when changing the audio output device of a sampler
188     channel with loaded instrument and start playing notes
189 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
190 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
191     PowerPC, which probably could cause crashes on that platform
192 persson 1889 - fixed a memory management error which could cause a crash when a
193     plugin was unloaded
194 persson 1896 - bugfix: two private structs had the same name, which could cause
195     problems if the linker chose the wrong constructor
196 iliev 1761
197    
198 schoenebeck 1560 Version 0.5.1 (6 December 2007)
199 schoenebeck 1454
200     * packaging changes:
201     - added autoconf checks for pthread library
202     - added autoconf check for pthread bug found on certain NPTL-enabled
203     glibc versions (see Gentoo bug report #194076)
204 senoner 1502 - added autoconf checks for MS Windows
205 schoenebeck 1454
206 persson 1455 * general changes:
207     - bugfix: the thread used by an editor plugin didn't die when the
208     editor closed
209 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
210     out all the space. operator--() did not apply size_mask after
211     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
212     order to avoid problems with the _NonVolatileReader functions.
213     - bugfix: Stream.h: added a missing divide by BytesPerSample in
214     GetWriteSpace(). Since this function is currently only used in
215     the stream's qsort() compare function, it didn't trigger any
216     bugs.
217     - Resampler.h, Synthesizer.h: cubic interpolation now works in
218     24bit mode too. Faster method to read 24bit words on little
219     endian machines (x86): replaced 3 byte reads + shifts with a 1
220     unaligned 32bit read and shift
221     - experimental support for MS Windows (MIDI input via MME, AUDIO
222     output via ASIO)
223     - made handling of SIGINT signal (Ctrl-C) a bit more robust
224 iliev 1541 - support for monitoring the total number of active disk streams
225     (new LSCP commands: GET TOTAL_STREAM_COUNT,
226     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
227 persson 1455
228 senoner 1500 * AUDIO driver:
229 persson 1534 - added Windows ASIO low latency audio driver
230 senoner 1500
231 senoner 1485 * MIDI driver:
232 schoenebeck 1495 - added MME Windows MIDI driver
233 senoner 1485
234 schoenebeck 1471 * LSCP server:
235     - added support for Windows style path / filenames, however with
236     forward slash path separators instead of backslash
237     (i.e. "C:/foo/bar.gig")
238 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
239     apostrophes as well
240 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
241     "LIST FILE INSTRUMENTS <file>" and
242     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
243     about an arbitrary instrument file on the system where the sampler is
244     running on
245 schoenebeck 1471
246 schoenebeck 1424 Version 0.5.0 (15 October 2007)
247 schoenebeck 947
248 schoenebeck 1065 * packaging changes:
249 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
250     API header files anymore
251 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
252     the Doxygen API documentation (explicitly listed in Doxyfile.in)
253 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
254     capable to execute our autoconf environment, thus no need anymore
255     to maintain the compile time configuration file (osx/version.h) for
256     OSX manually (patch by Toshi Nagata)
257 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
258     parameters
259 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
260     C++ API header files, all implementation internal global definitions
261     are now in global_private.h
262     - atomic.h is not exposed to the C++ API anymore
263     - no need to include config.h anymore for using LS's API header files
264     - fixed warnings in API doc generation
265 schoenebeck 1065
266 schoenebeck 947 * general changes:
267     - replaced the old, confusing MIDI program change mechanism by a
268     flexible MIDI instrument mapper which allows to map arbitrary
269 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
270 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
271     loaded on the respective channel when such MIDI program change
272     messages arrive, beside that, each entry allows to define a life-time
273     strategy for the instrument, so the user can define whether the
274     instrument should i.e. be permanently loaded (to be able to switch
275     quickly among sounds) or i.e. loaded just on demand when the
276     respective program change arrives (to safe RAM space), as well as a
277     global volume factor for each entry, so the user can adjust the volume
278     dynamic of his mapped instrument collection without having to modify
279 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
280     MIDI instrument maps and assign each sampler channel individually
281     a certain map, so that i.e. separation of normal instruments and
282     drumkits is possible
283 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
284     MIDI instrument maps, MIDI instruments, FX sends, global volume.
285 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
286     due to a constant size RingBuffer FIFO which is now replaced by a
287     dynamic (unlimited) size std::list FIFO
288 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
289     output channels for being processed by external effect processors
290     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
291     controllers
292 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
293 iliev 1130 - Implemented new, improved notification system
294 schoenebeck 1149 - fixed compilation errors regarding OSX
295     (patch by Toshi Nagata)
296 iliev 1161 - implemented instruments database
297 iliev 1345 - added support for escape sequences to the instruments database
298 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
299     within the sampler's process (by using instrument editor plugins),
300     you'll notice the new "Registered instrument editors:" message on
301 schoenebeck 1407 startup, added a new LSCP command:
302     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
303 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
304     given sampler channel, the plugin path can be overridden at compile
305     time with ./configure --enable-plugin-dir=/some/dir
306 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
307     in the sampler's process to safely edit instruments while playing
308     without a crash (hopefully) by either suspending single regions
309     wherever possible or if unavoidable whole engine(s)
310 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
311     policy and priority on thread level, set a minimum stack size for
312     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
313     threads simply inherited properties of starting thread instead of
314     setting their own policy and priority
315 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
316     main process did not wait for the stack trace process to finish
317     its output
318 persson 1248 - fixed some minor memory leaks
319 schoenebeck 1259 - reenabled assembly features support, at the moment only for
320     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
321 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
322     register, to avoid relocations in the text segment at runtime)
323 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
324 schoenebeck 947
325     * MIDI driver:
326     - dispatch bank select (MSB and LSB) messages
327    
328 schoenebeck 1049 * audio driver:
329     - the ALSA audio output driver parameters now reflect the correct
330     parameter value ranges for the respective selected sound card
331     (patch by Till Wimmer, a bit fixed and extended)
332    
333 persson 951 * Gigasampler format engine:
334     - if a filter is used and EG2 finishes before EG1, let the voice
335     die when EG2 has finished (this fixes a problem with clicks and
336     voice starvation for some gigs)
337 persson 1038 - playback is no longer disabled during instrument loading
338     - all notes playing on a channel that changes its instrument keep
339     playing with the old instrument until they get a note off
340     command
341 persson 1039 - EG fix: a release value of zero could cause noises or crash
342 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
343 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
344     above max sustain level, which means that there is a decay phase
345     even if sustain is 100%
346 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
347     noises or crashes
348 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
349 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
350     supplied to the configure script (fixes #46)
351 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
352     instead of a fix value
353 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
354     127 (solo mode) only kill voices if the respective mode really
355     changed
356 persson 951
357 schoenebeck 1244 * LSCP server:
358     - fixed compile time error for old Bison versions
359     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
360 schoenebeck 1245 - parser now supports extended ASCII character set
361     (up to ASCII code 255, i.e. includes now umlauts and accents)
362     - filename arguments in LSCP commands now allow to use escape
363     sequences, that is directly literal as one of: \', \", \\, \n, \r,
364     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
365     code value like \xf2) (fixes bug #24)
366 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
367     least one of their text-based parameters (i.e. name, description):
368     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
369     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
370     "SET DB_INSTRUMENT_DIRECTORY NAME",
371     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
372     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
373     "FIND DB_INSTRUMENT_DIRECTORIES"
374 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
375     occured, the unexpected character and the actually expected, possible
376     character(s), the latter only if less than 5 possibilities)
377 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
378     settings
379 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
380     of strings were treated as being one string containing commas
381     (fixes #57)
382 schoenebeck 1244
383 iliev 959 * Bug fixes:
384     - fixed crash occurring on certain LSCP scripts (Bug 39)
385 persson 1038 - another thread safety fix for lscp "load engine" and "set
386     channel audio output device"
387 iliev 1283 - fixed a crash which occurs when reassigning the same engine
388     on a sampler channel with connected MIDI device
389 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
390     device connected to a sampler channel to number less then or equal
391     to the index of the port to which the sampler channel is connected.
392 iliev 1296 - The previous bindings were not been disconnected when altering
393     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
394     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
395 iliev 1297 - The active stream/voice count statistic was incorrect.
396 iliev 1298 - notification events were not been sent for some sampler
397     channel changes
398 iliev 1305 - added default min and max values to restrict the number of allowed
399     audio output channels and MIDI input ports
400 iliev 1306 - the connection to the PCM interface is now closed when destroying
401     an audio output device
402 schoenebeck 1332 - files with slash in their path or filename could not be loaded
403 iliev 959
404 schoenebeck 1221 * test cases:
405     - updated and fixed (haven't been touched in a while)
406    
407 schoenebeck 937 Version 0.4.0 (24 November 2006)
408 persson 696
409 schoenebeck 697 * packaging changes:
410 capela 868 - changed deprecated copyright attribute to license; added ldconfig
411     to post-(un)install steps; added devel package for liblinuxsampler;
412     to linuxsampler.spec (RPM)
413 schoenebeck 697 - install necessary development header files for allowing 3rd party
414     applications to link against liblinuxsampler
415     - liblinuxsampler's API documentation can be generated with 'make docs'
416     (Doxygen required)
417 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
418     implementation (currently either an integer math solution or a
419     di-harmonic approximation), automatic detection can be overriden
420     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
421     configure script argument though (mandatory for cross-compilation)
422 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
423     provided some on his own (as CXXFLAGS)
424 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
425     messages
426 schoenebeck 852 - added compile time options to allow disabling the various audio and
427     MIDI drivers
428 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
429     (patch by Ebrahim Mayat)
430 schoenebeck 697
431 persson 696 * Gigasampler format engine:
432 schoenebeck 738 - extensive synthesis optimization
433     (reimplementation of EGs and LFO(s), removed synthesis parameter
434     prerendering and the synthesis parameter matrix in general, splitting
435     each audio fragment into subfragments now where each subfragment uses
436 persson 830 constant pitch and filter coefficients. The volume coefficient is
437     linearly interpolated inside a subfragment, unless
438     --disable-interpolate-volume is set.)
439 persson 696 - fine tuning of the EG modulation parameters
440 persson 729 - improved filter cutoff calculation by adding support for the
441     following gig parameters: Cutoff freq (used when no cutoff
442     controller is defined), Control invert, Minimum cutoff, Velocity
443 persson 791 curve and Velocity range. The keyboard tracking now scales
444     cutoff frequency instead of resonance.
445 persson 877 - added support for gig parameter Resonance.
446 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
447 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
448     which can be overridden with --enable-global-attenuation
449 persson 783 - EG fixes: made the length of "attack hold" stage more
450     accurate. Release stage can now start before attack stage
451 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
452     time now has a minimal value to prevent clicks.
453 persson 799 - fixed pitch changes larger than one octave
454 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
455     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
456     all modes can be altered via standard GM messages, that is CC5 for
457     altering portamento time, CC65 for enabling / disabling portamento
458     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
459 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
460     parameter) and crossfade
461 persson 831 - added support for the "attenuation controller threshold" gig
462     parameter
463 persson 832 - added smoothing of volume changes caused by control change
464     messages
465 persson 865 - sample loop parameters are now taken from the DimensionRegion
466     instead of the wave chunk
467     - fixed keyswitching for v3 gigs with a number of keyswitch splits
468     not equal to a power of two
469 persson 877 - reimplementation of the filter algorithm. The new filter is more
470     accurate and supports all gig filter types, including bandreject
471     and lowpass turbo.
472 persson 903 - real support for 24 bit samples - samples are not truncated to
473     16 bits anymore
474     - support for aftertouch (channel pressure, not polyphonic
475     aftertouch)
476 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
477     amplifying from 0)
478 persson 696
479 schoenebeck 711 * LSCP server:
480     - fixed application exit on broken pipe error (fixes bug #20)
481 iliev 793 - fixed the notification messages delay due to lack of
482     network activity (fixes bug #26)
483 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
484     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
485 schoenebeck 711
486 schoenebeck 838 * audio driver:
487     - added aRts audio output driver (by no means RT safe)
488    
489 schoenebeck 775 * MIDI driver:
490     - fixed legacy sysex code which caused dispatching of MIDI SysEx
491     messages several times instead of once
492 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
493     for events (i.e. for offline rendering based MIDI drivers)
494 persson 922 - added checks for bad MIDI data
495 schoenebeck 775
496 schoenebeck 900 * linuxsampler application:
497     - show available sampler engine types on startup
498    
499 schoenebeck 705 * general changes:
500     - support for muting sampler channels and solo mode of the same, two new
501     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
502     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
503     introduced for this, the behavior is the same like on a mixer console
504 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
505     --enable-process-muted-channels which can be used to enable the
506     processing of muted channels.
507 iliev 777 - support for sostenuto pedal
508 iliev 779 - support for monitoring the total number of active voices
509 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
510     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
511 persson 835 - fixed some memory management errors
512 persson 841 - fixed some concurrency problems that could lead to crashes when
513     LSCP commands were executed
514 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
515     sampler channel (fixes bug #36)
516 schoenebeck 705
517 schoenebeck 692 Version 0.3.3 (15 July 2005)
518 schoenebeck 686
519     * packaging changes:
520     - fixed compilation with gcc 4.0
521    
522 schoenebeck 687 * Gigasampler format engine:
523     - LFO preprocessing was performed even though the respective LFO was
524     disabled by the instrument patch (minor efficiency fix)
525 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
526     for volume ramp downs in the same fragment (needed for current voice
527     stealing implementation) then simply inform the user with a warning
528     about possible click sounds and reduce the volume ramp down
529     appropriately instead of cancelling the audio device connection
530 schoenebeck 687
531 schoenebeck 677 Version 0.3.2 (24 June 2005)
532 schoenebeck 609
533     * packaging changes:
534     - updated autotools build files to compile on OS X
535     (conditional compilation of CoreMIDI and MidiShare drivers)
536 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
537     './configure --disable-asm' (definitely not recommended)
538 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
539     - require automake (>= 1.5) for 'make -f Makefile.cvs'
540     (due to 'dist-bzip2' automake option)
541 schoenebeck 649
542     * Gigasampler format engine:
543     - support for the gig parameters for "release velocity response" curves
544     - fine tuning of the EGADSR envelope
545     - volume of release triggered samples now depends on note-on velocity,
546     note length and gig parameter "release trigger decay" instead of
547     note-off velocity.
548 schoenebeck 663 - revised voice stealing
549     (fixes crash and endless loop caused by voice stealing)
550 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
551 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
552     instead of when the respective voice is actually launched
553     (fixes undefined behavior if stolen voices belonged to a key group -
554     this case was followed by a "killed voice survived" error message)
555 schoenebeck 669 - fixed minor issue with null/silence samples
556     (those stole voices even though they don't need a voice at all which
557     resulted in "voice stealing didn't work out" messages)
558 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
559     instrument or audio output device change
560 schoenebeck 654
561 schoenebeck 620 * LSCP server:
562 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
563 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
564 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
565 schoenebeck 609
566 schoenebeck 668 * linuxsampler application:
567     - added command line parameters --lscp-addr and --lscp-port to override
568     default IP address and port of LSCP server
569    
570 schoenebeck 579 Version 0.3.1 (24 May 2005)
571    
572     * initial release
