File size: 30387 byte(s)
* VST: look for the Fantasia binary in liblinuxsampler.dll's directory and
  in its parent directory (required for the next Windows installer which
  allows to install the 64 bit and 32 bit version of LinuxSampler VST
  alongside)

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 schoenebeck 1928 directory of liblinuxsampler dll (look in the same directory and one
17     directory above)
18 persson 1899 - configure script fix: removed unconditional use of SSE
19 persson 1923 - fixed building with sqlite installed in a non-standard directory
20 schoenebeck 1639
21 schoenebeck 1601 * general changes:
22     - bugfix: on some POSIX systems instrument editor plugins refused to
23     load as we used a non-portable Linux specific struct field
24     (fixes bug #70, patch by Ronald Baljeu)
25 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
26     plugin DLL on Windows systems failed
27 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded
28     - optimized the SynchronizedConfig class so it doesn't wait
29     unnecessarily long after an update
30 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
31     events (e.g. to highlight the pressed keys on the virtual keyboard
32     of gigedit)
33 schoenebeck 1659 - added support for triggering notes by instrument editors (see above)
34 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
35 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation
36     is only used by very few systems, most pick the int math
37     implementation, which is usually faster)
38 persson 1748 - fixes for audio drivers with varying buffer sizes
39 persson 1777 - experimental support for running LinuxSampler as a DSSI, LV2 and
40     VST plugin
41 iliev 1789 - notification events for stream/voice count statistics are now sent
42     only when there are actual changes
43 persson 1790 - added memory ordering constraints to improve stability on
44     multi-core and multi-cpu systems
45 schoenebeck 1800 - maximum voices and disk streams can now be altered at runtime
46 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
47 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
48     be switched on by command line option "--stacktrace" (the automatic
49     stacktrace mechanism seems to be broken on most systems at the moment)
50 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
51     a pointer to the launched InstrumentEditor object
52 schoenebeck 1876 - added optional 3rd party user data parameter for following
53     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
54     InstrumentEditor::Launch(),
55     InstrumentManager::LaunchInstrumentEditor()
56 persson 1887 - theoretical fix: made SynchronizedConfig follow C++0x memory
57     model more strictly
58 persson 1895 - fixes for using large audio device buffers
59 schoenebeck 1601
60 schoenebeck 1599 * audio driver:
61     - removed the nonsense audio channel constraint (which was hard coded to
62     max. 100 audio channels) for most audio drivers
63 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
64     opposed to the LSCP specs
65 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
66     reflected the wrong value
67 persson 1644 - fixed a memory management bug in ASIO driver
68 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used
69 persson 1777 - JACK: use jack_client_open instead of the deprecated
70 persson 1748 jack_client_new
71 iliev 1829 - added (experimental) CoreAudio driver
72 persson 1888 - applied old fixes to the ASIO driver that were included in the
73     previous binary release but accidentally never committed to CVS
74     (fixes #117)
75 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
76     win64)
77 persson 1895 - VST: added support for sample rate and buffer size changes
78     - VST: close editor (Fantasia) when the VST is removed
79 persson 1908 - VST: avoid opening Fantasia more than once for each VST instance
80     - VST: export main function as "main" on Linux too (fix for
81     energyXT)
82 persson 1917 - VST: changed number of output channels from one stereo to 16
83     stereo
84 persson 1922 - added channel routing, fxsends and midi maps to the settings
85     stored in the plugin state
86 schoenebeck 1599
87 persson 1651 * MIDI driver:
88     - added JACK MIDI driver
89 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
90     want to (mis)use it for some purpose ("fixed" in all current MIDI
91     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
92 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
93 persson 1887 CoreMidi or AU
94 persson 1889 - fixed mingw-w64 compilation error in MME driver
95 persson 1924 - made program change handling in MIDI thread real-time safe by
96     moving the logic to a non-RT thread
97 persson 1651
98 schoenebeck 1604 * instruments database:
99 iliev 1603 - avoid time consuming samples scanning when adding instruments
100     to the instruments database
101 iliev 1727 - added support for handling lost files in the instruments database
102 iliev 1781 - Implemented option for adding instruments in separate directories
103     in the instruments database
104     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
105 persson 1908 - work-around for missing fnmatch function on Windows to make
106     instrument database compilable
107 senoner 1910 - added instrument database support on Windows
108 senoner 1911 works with both standalone mode and VST plugin.
109     the instruments DB file is located in
110     %USERPROFILE%\.linuxsampler\instruments.db which allows different
111     databases for each windows user
112 schoenebeck 1928 if no DB is present it automatically creates the .linuxsampler subdir
113 senoner 1912 and then creates an empty DB
114 iliev 1603
115 persson 1644 * Gigasampler format engine:
116     - fixed a memory leak that could happen when a channel was deleted
117     while notes were playing
118 persson 1646 - made it possible to load an instrument even if the audio thread
119     isn't running
120 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
121     enough for piano gigs with pedal noise samples
122 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
123     respective FX send MIDI controller was used
124 schoenebeck 1724 - added support for GM global device volume SysEx message
125 schoenebeck 1762 (can be selected at compile time to either apply globally to the
126     whole sampler [default] or only to the sampler channels that are
127     connected to the respective MIDI input port the SysEx message arrived
128     on)
129 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
130     sometimes wrongly killed in the same buffer, causing no sound to
131     be played
132 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
133     which is usally used to switch a part between chromatic sounds and
134     drumkit sounds (as opposed to their common default setting of MIDI
135     part 10 being a drumkit part and all other ones chromatic parts), in
136     LS however one can switch between the first 16 MIDI instrument maps
137     defined for the sampler
138 persson 1764 - made it possible to create multiple sample channels even if the
139     audio thread isn't running
140 persson 1844 - fixed crash when removing channel with active voices (#116)
141 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
142     un-cache the respective sample if it's really not used by any
143     sampler engine anymore
144     - re-cache samples in case they were changed by an instrument editor,
145     e.g. when a sample was added while playing (#82)
146 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
147     same time stamp as the voice's note-on event and occured both in the
148     same audio fragment cycle (fixes bug #112)
149 persson 1858 - added support for the "fine tune" and "pitch bend range"
150     instrument-level gig parameters
151     - fixed minor artifacts in pitch bend handling
152 schoenebeck 1860 - added support for GS Reset SysEx message
153 persson 1862 - allow gig files to use unlimited downward pitch shifting
154     - added a limit check for upward pitch shifting
155 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
156     note was silent
157 persson 1923 - fixed crash happening when a pitch bend event arrived at the
158     same time a new instrument was loading
159 persson 1644
160 schoenebeck 1687 * LSCP server:
161     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
162     react on MIDI data arriving on certain sampler channels (so far only
163     Note-On and Note-Off events are sent via this LSCP event)
164 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
165     react on MIDI data arriving on certain MIDI input devices (so far only
166     Note-On and Note-Off events are sent via this LSCP event)
167 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
168     SET DB_INSTRUMENT FILE_PATH
169 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
170     frontends to send MIDI messages to specific sampler channel
171     - added two additional fields to GET FILE INSTRUMENT INFO command -
172     KEY_BINDINGS and KEYSWITCH_BINDINGS
173 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
174     was incorrect
175 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
176 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
177     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
178     be triggered respectively
179     - added new LSCP command "SET STREAMS" to globally alter the maximum
180     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
181     which will be triggered respectively
182 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
183     a gigedit file dialog is opened)
184 iliev 1848 - close all connections when LSCPServer is deleted
185 iliev 1882 - hard close of all sockets on exit
186 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
187     driver
188 schoenebeck 1687
189 iliev 1761 * Bug fixes:
190     - fixed a crash which occurs when removing a sampler channel waiting
191     to start instrument loading after another channel
192 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
193     instrument loading in progress (bug #113)
194 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
195     instrument with PERSISTENT load mode
196 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
197     - fixed memory leaks when issuing the following LSCP commands:
198     GET AUDIO_OUTPUT_DRIVER INFO
199     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
200     GET MIDI_INPUT_DRIVER INFO
201     GET MIDI_INPUT_DRIVER_PARAMETER INFO
202     - fixed possible compilation error when sqlite is not present
203 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
204 iliev 1847 - fixed crash when changing the audio output device of a sampler
205     channel with loaded instrument and start playing notes
206 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
207 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
208     PowerPC, which probably could cause crashes on that platform
209 persson 1889 - fixed a memory management error which could cause a crash when a
210     plugin was unloaded
211 persson 1896 - bugfix: two private structs had the same name, which could cause
212     problems if the linker chose the wrong constructor
213 iliev 1761
214    
215 schoenebeck 1560 Version 0.5.1 (6 December 2007)
216 schoenebeck 1454
217     * packaging changes:
218     - added autoconf checks for pthread library
219     - added autoconf check for pthread bug found on certain NPTL-enabled
220     glibc versions (see Gentoo bug report #194076)
221 senoner 1502 - added autoconf checks for MS Windows
222 schoenebeck 1454
223 persson 1455 * general changes:
224     - bugfix: the thread used by an editor plugin didn't die when the
225     editor closed
226 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
227     out all the space. operator--() did not apply size_mask after
228     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
229     order to avoid problems with the _NonVolatileReader functions.
230     - bugfix: Stream.h: added a missing divide by BytesPerSample in
231     GetWriteSpace(). Since this function is currently only used in
232     the stream's qsort() compare function, it didn't trigger any
233     bugs.
234     - Resampler.h, Synthesizer.h: cubic interpolation now works in
235     24bit mode too. Faster method to read 24bit words on little
236     endian machines (x86): replaced 3 byte reads + shifts with a 1
237     unaligned 32bit read and shift
238     - experimental support for MS Windows (MIDI input via MME, AUDIO
239     output via ASIO)
240     - made handling of SIGINT signal (Ctrl-C) a bit more robust
241 iliev 1541 - support for monitoring the total number of active disk streams
242     (new LSCP commands: GET TOTAL_STREAM_COUNT,
243     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
244 persson 1455
245 senoner 1500 * AUDIO driver:
246 persson 1534 - added Windows ASIO low latency audio driver
247 senoner 1500
248 senoner 1485 * MIDI driver:
249 schoenebeck 1495 - added MME Windows MIDI driver
250 senoner 1485
251 schoenebeck 1471 * LSCP server:
252     - added support for Windows style path / filenames, however with
253     forward slash path separators instead of backslash
254     (i.e. "C:/foo/bar.gig")
255 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
256     apostrophes as well
257 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
258     "LIST FILE INSTRUMENTS <file>" and
259     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
260     about an arbitrary instrument file on the system where the sampler is
261     running on
262 schoenebeck 1471
263 schoenebeck 1424 Version 0.5.0 (15 October 2007)
264 schoenebeck 947
265 schoenebeck 1065 * packaging changes:
266 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
267     API header files anymore
268 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
269     the Doxygen API documentation (explicitly listed in Doxyfile.in)
270 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
271     capable to execute our autoconf environment, thus no need anymore
272     to maintain the compile time configuration file (osx/version.h) for
273     OSX manually (patch by Toshi Nagata)
274 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
275     parameters
276 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
277     C++ API header files, all implementation internal global definitions
278     are now in global_private.h
279     - atomic.h is not exposed to the C++ API anymore
280     - no need to include config.h anymore for using LS's API header files
281     - fixed warnings in API doc generation
282 schoenebeck 1065
283 schoenebeck 947 * general changes:
284     - replaced the old, confusing MIDI program change mechanism by a
285     flexible MIDI instrument mapper which allows to map arbitrary
286 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
287 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
288     loaded on the respective channel when such MIDI program change
289     messages arrive, beside that, each entry allows to define a life-time
290     strategy for the instrument, so the user can define whether the
291     instrument should i.e. be permanently loaded (to be able to switch
292     quickly among sounds) or i.e. loaded just on demand when the
293     respective program change arrives (to safe RAM space), as well as a
294     global volume factor for each entry, so the user can adjust the volume
295     dynamic of his mapped instrument collection without having to modify
296 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
297     MIDI instrument maps and assign each sampler channel individually
298     a certain map, so that i.e. separation of normal instruments and
299     drumkits is possible
300 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
301     MIDI instrument maps, MIDI instruments, FX sends, global volume.
302 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
303     due to a constant size RingBuffer FIFO which is now replaced by a
304     dynamic (unlimited) size std::list FIFO
305 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
306     output channels for being processed by external effect processors
307     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
308     controllers
309 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
310 iliev 1130 - Implemented new, improved notification system
311 schoenebeck 1149 - fixed compilation errors regarding OSX
312     (patch by Toshi Nagata)
313 iliev 1161 - implemented instruments database
314 iliev 1345 - added support for escape sequences to the instruments database
315 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
316     within the sampler's process (by using instrument editor plugins),
317     you'll notice the new "Registered instrument editors:" message on
318 schoenebeck 1407 startup, added a new LSCP command:
319     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
320 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
321     given sampler channel, the plugin path can be overridden at compile
322     time with ./configure --enable-plugin-dir=/some/dir
323 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
324     in the sampler's process to safely edit instruments while playing
325     without a crash (hopefully) by either suspending single regions
326     wherever possible or if unavoidable whole engine(s)
327 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
328     policy and priority on thread level, set a minimum stack size for
329     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
330     threads simply inherited properties of starting thread instead of
331     setting their own policy and priority
332 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
333     main process did not wait for the stack trace process to finish
334     its output
335 persson 1248 - fixed some minor memory leaks
336 schoenebeck 1259 - reenabled assembly features support, at the moment only for
337     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
338 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
339     register, to avoid relocations in the text segment at runtime)
340 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
341 schoenebeck 947
342     * MIDI driver:
343     - dispatch bank select (MSB and LSB) messages
344    
345 schoenebeck 1049 * audio driver:
346     - the ALSA audio output driver parameters now reflect the correct
347     parameter value ranges for the respective selected sound card
348     (patch by Till Wimmer, a bit fixed and extended)
349    
350 persson 951 * Gigasampler format engine:
351     - if a filter is used and EG2 finishes before EG1, let the voice
352     die when EG2 has finished (this fixes a problem with clicks and
353     voice starvation for some gigs)
354 persson 1038 - playback is no longer disabled during instrument loading
355     - all notes playing on a channel that changes its instrument keep
356     playing with the old instrument until they get a note off
357     command
358 persson 1039 - EG fix: a release value of zero could cause noises or crash
359 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
360 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
361     above max sustain level, which means that there is a decay phase
362     even if sustain is 100%
363 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
364     noises or crashes
365 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
366 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
367     supplied to the configure script (fixes #46)
368 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
369     instead of a fix value
370 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
371     127 (solo mode) only kill voices if the respective mode really
372     changed
373 persson 951
374 schoenebeck 1244 * LSCP server:
375     - fixed compile time error for old Bison versions
376     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
377 schoenebeck 1245 - parser now supports extended ASCII character set
378     (up to ASCII code 255, i.e. includes now umlauts and accents)
379     - filename arguments in LSCP commands now allow to use escape
380     sequences, that is directly literal as one of: \', \", \\, \n, \r,
381     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
382     code value like \xf2) (fixes bug #24)
383 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
384     least one of their text-based parameters (i.e. name, description):

391 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
392     occured, the unexpected character and the actually expected, possible
393     character(s), the latter only if less than 5 possibilities)
394 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
395     settings
396 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
397     of strings were treated as being one string containing commas
398     (fixes #57)
399 schoenebeck 1244
400 iliev 959 * Bug fixes:
401     - fixed crash occurring on certain LSCP scripts (Bug 39)
402 persson 1038 - another thread safety fix for lscp "load engine" and "set
403     channel audio output device"
404 iliev 1283 - fixed a crash which occurs when reassigning the same engine
405     on a sampler channel with connected MIDI device
406 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
407     device connected to a sampler channel to number less then or equal
408     to the index of the port to which the sampler channel is connected.
409 iliev 1296 - The previous bindings were not been disconnected when altering
410     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
411     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
412 iliev 1297 - The active stream/voice count statistic was incorrect.
413 iliev 1298 - notification events were not been sent for some sampler
414     channel changes
415 iliev 1305 - added default min and max values to restrict the number of allowed
416     audio output channels and MIDI input ports
417 iliev 1306 - the connection to the PCM interface is now closed when destroying
418     an audio output device
419 schoenebeck 1332 - files with slash in their path or filename could not be loaded
420 iliev 959
421 schoenebeck 1221 * test cases:
422     - updated and fixed (haven't been touched in a while)
423    
424 schoenebeck 937 Version 0.4.0 (24 November 2006)
425 persson 696
426 schoenebeck 697 * packaging changes:
427 capela 868 - changed deprecated copyright attribute to license; added ldconfig
428     to post-(un)install steps; added devel package for liblinuxsampler;
429     to linuxsampler.spec (RPM)
430 schoenebeck 697 - install necessary development header files for allowing 3rd party
431     applications to link against liblinuxsampler
432     - liblinuxsampler's API documentation can be generated with 'make docs'
433     (Doxygen required)
434 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
435     implementation (currently either an integer math solution or a
436     di-harmonic approximation), automatic detection can be overriden
437     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
438     configure script argument though (mandatory for cross-compilation)
439 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
440     provided some on his own (as CXXFLAGS)
441 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
442     messages
443 schoenebeck 852 - added compile time options to allow disabling the various audio and
444     MIDI drivers
445 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
446     (patch by Ebrahim Mayat)
447 schoenebeck 697
448 persson 696 * Gigasampler format engine:
449 schoenebeck 738 - extensive synthesis optimization
450     (reimplementation of EGs and LFO(s), removed synthesis parameter
451     prerendering and the synthesis parameter matrix in general, splitting
452     each audio fragment into subfragments now where each subfragment uses
453 persson 830 constant pitch and filter coefficients. The volume coefficient is
454     linearly interpolated inside a subfragment, unless
455     --disable-interpolate-volume is set.)
456 persson 696 - fine tuning of the EG modulation parameters
457 persson 729 - improved filter cutoff calculation by adding support for the
458     following gig parameters: Cutoff freq (used when no cutoff
459     controller is defined), Control invert, Minimum cutoff, Velocity
460 persson 791 curve and Velocity range. The keyboard tracking now scales
461     cutoff frequency instead of resonance.
462 persson 877 - added support for gig parameter Resonance.
463 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
464 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
465     which can be overridden with --enable-global-attenuation
466 persson 783 - EG fixes: made the length of "attack hold" stage more
467     accurate. Release stage can now start before attack stage
468 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
469     time now has a minimal value to prevent clicks.
470 persson 799 - fixed pitch changes larger than one octave
471 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
472     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
473     all modes can be altered via standard GM messages, that is CC5 for
474     altering portamento time, CC65 for enabling / disabling portamento
475     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
476 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
477     parameter) and crossfade
478 persson 831 - added support for the "attenuation controller threshold" gig
479     parameter
480 persson 832 - added smoothing of volume changes caused by control change
481     messages
482 persson 865 - sample loop parameters are now taken from the DimensionRegion
483     instead of the wave chunk
484     - fixed keyswitching for v3 gigs with a number of keyswitch splits
485     not equal to a power of two
486 persson 877 - reimplementation of the filter algorithm. The new filter is more
487     accurate and supports all gig filter types, including bandreject
488     and lowpass turbo.
489 persson 903 - real support for 24 bit samples - samples are not truncated to
490     16 bits anymore
491     - support for aftertouch (channel pressure, not polyphonic
492     aftertouch)
493 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
494     amplifying from 0)
495 persson 696
496 schoenebeck 711 * LSCP server:
497     - fixed application exit on broken pipe error (fixes bug #20)
498 iliev 793 - fixed the notification messages delay due to lack of
499     network activity (fixes bug #26)
500 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
501     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
502 schoenebeck 711
503 schoenebeck 838 * audio driver:
504     - added aRts audio output driver (by no means RT safe)
505    
506 schoenebeck 775 * MIDI driver:
507     - fixed legacy sysex code which caused dispatching of MIDI SysEx
508     messages several times instead of once
509 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
510     for events (i.e. for offline rendering based MIDI drivers)
511 persson 922 - added checks for bad MIDI data
512 schoenebeck 775
513 schoenebeck 900 * linuxsampler application:
514     - show available sampler engine types on startup
515    
516 schoenebeck 705 * general changes:
517     - support for muting sampler channels and solo mode of the same, two new
518     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
519     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
520     introduced for this, the behavior is the same like on a mixer console
521 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
522     --enable-process-muted-channels which can be used to enable the
523     processing of muted channels.
524 iliev 777 - support for sostenuto pedal
525 iliev 779 - support for monitoring the total number of active voices
526 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
527     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
528 persson 835 - fixed some memory management errors
529 persson 841 - fixed some concurrency problems that could lead to crashes when
530     LSCP commands were executed
531 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
532     sampler channel (fixes bug #36)
533 schoenebeck 705
534 schoenebeck 692 Version 0.3.3 (15 July 2005)
535 schoenebeck 686
536     * packaging changes:
537     - fixed compilation with gcc 4.0
538    
539 schoenebeck 687 * Gigasampler format engine:
540     - LFO preprocessing was performed even though the respective LFO was
541     disabled by the instrument patch (minor efficiency fix)
542 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
543     for volume ramp downs in the same fragment (needed for current voice
544     stealing implementation) then simply inform the user with a warning
545     about possible click sounds and reduce the volume ramp down
546     appropriately instead of cancelling the audio device connection
547 schoenebeck 687
548 schoenebeck 677 Version 0.3.2 (24 June 2005)
549 schoenebeck 609
550     * packaging changes:
551     - updated autotools build files to compile on OS X
552     (conditional compilation of CoreMIDI and MidiShare drivers)
553 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
554     './configure --disable-asm' (definitely not recommended)
555 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
556     - require automake (>= 1.5) for 'make -f Makefile.cvs'
557     (due to 'dist-bzip2' automake option)
558 schoenebeck 649
559     * Gigasampler format engine:
560     - support for the gig parameters for "release velocity response" curves
561     - fine tuning of the EGADSR envelope
562     - volume of release triggered samples now depends on note-on velocity,
563     note length and gig parameter "release trigger decay" instead of
564     note-off velocity.
565 schoenebeck 663 - revised voice stealing
566     (fixes crash and endless loop caused by voice stealing)
567 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
568 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
569     instead of when the respective voice is actually launched
570     (fixes undefined behavior if stolen voices belonged to a key group -
571     this case was followed by a "killed voice survived" error message)
572 schoenebeck 669 - fixed minor issue with null/silence samples
573     (those stole voices even though they don't need a voice at all which
574     resulted in "voice stealing didn't work out" messages)
575 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
576     instrument or audio output device change
577 schoenebeck 654
578 schoenebeck 620 * LSCP server:
579 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
580 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
581 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
582 schoenebeck 609
583 schoenebeck 668 * linuxsampler application:
584     - added command line parameters --lscp-addr and --lscp-port to override
585     default IP address and port of LSCP server
586    
587 schoenebeck 579 Version 0.3.1 (24 May 2005)
588    
589     * initial release
