File size: 33630 byte(s)
* sfz engine: added support for random, seq_position, seq_length and
  volume

1 schoenebeck 1993 Version CVS HEAD (?)
2    
3 iliev 2012 * General changes:
4     - Refactoring: moved the independent code from
5     the Gigasampler format engine to base classes
6 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
7     respective profiling code is currently broken
8 schoenebeck 2053 - Introduced support for optional environment variable
9     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
10     where the sampler shall look for instrument editor plugins
11     (patch by Luis Garrido, slightly modified).
12 iliev 2012
13 persson 2043 * Gigasampler format engine:
14     - implemented the "round robin keyboard" dimension
15     - fixed round robin and random dimensions for cases when number of
16     dimension zones is not a power of two
17     - made round robin use a counter for each region instead of each
18     key
19    
20 schoenebeck 2047 * SFZ format engine:
21 iliev 2012 - Initial implementation (not usable yet)
22 persson 2055 - added support for v2 multiple stage envelope generators
23     - added a fine-tuned v1 envelope generator instead of using the
24     one from the gig engine
25 persson 2058 - fixed memory leak and memory handling errors
26 persson 2061 - added support for trigger=first, trigger=legato and sw_previous
27 persson 2058 - allow non-numerical key values ("C#4" for example)
28     - "key" opcode now sets pitch_keycenter too
29     - fixed error when unloading instrument with same sample used by
30     multiple regions
31     - added some opcode aliases, like loopmode for loop_mode, to be
32     more compatible

39 iliev 2012 - Initial implementation (not usable yet)
40    
41     * Host plugins:
42 schoenebeck 1993 - AU bugfix: failed to destroy its audio/MIDI devices
43 iliev 1994 - Listen to all interfaces on Mac OS X (INADDR_ANY)
44 persson 2045 - VST bugfix: If the host called resume() before and after
45     changing sample rate or block size, the number of channels was
46     incorrectly set to two. This caused silence in Cubase 5.
47 schoenebeck 1993
48     * MIDI driver:
49     - ALSA MIDI driver supports now "NAME" device parameter, for overriding
50     the ALSA sequencer client name

60 schoenebeck 1599
61 schoenebeck 1639 * packaging changes:
62     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
63     causing e.g. the libgig test to fail when
64     "./configure --disable-jack-driver" was used
65     (patch by Alexis Ballier)

74 schoenebeck 1928 directory of liblinuxsampler dll (look in the same directory and one
75     directory above)
76 persson 1899 - configure script fix: removed unconditional use of SSE
77 persson 1923 - fixed building with sqlite installed in a non-standard directory
78 persson 1931 - when cross-compiling, don't try to create instruments.db
79     - fix for new mingw-w64 version, which has usleep
80 schoenebeck 1639
81 schoenebeck 1601 * general changes:

83     load as we used a non-portable Linux specific struct field
84     (fixes bug #70, patch by Ronald Baljeu)
85 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
86     plugin DLL on Windows systems failed
87 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded
88     - optimized the SynchronizedConfig class so it doesn't wait
89     unnecessarily long after an update
90 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
91     events (e.g. to highlight the pressed keys on the virtual keyboard
92     of gigedit)
93 schoenebeck 1659 - added support for triggering notes by instrument editors (see above)
94 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
95 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation
96     is only used by very few systems, most pick the int math
97     implementation, which is usually faster)

106 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
107 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
108     be switched on by command line option "--stacktrace" (the automatic
109     stacktrace mechanism seems to be broken on most systems at the moment)
110 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
111     a pointer to the launched InstrumentEditor object
112 schoenebeck 1876 - added optional 3rd party user data parameter for following
113     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
114     InstrumentEditor::Launch(),
115     InstrumentManager::LaunchInstrumentEditor()
116 persson 1887 - theoretical fix: made SynchronizedConfig follow C++0x memory

122 schoenebeck 1601
123 schoenebeck 1599 * audio driver:
124     - removed the nonsense audio channel constraint (which was hard coded to
125     max. 100 audio channels) for most audio drivers
126 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
127     opposed to the LSCP specs
128 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
129     reflected the wrong value
130 persson 1644 - fixed a memory management bug in ASIO driver
131 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used

133 persson 1748 jack_client_new
134 iliev 1829 - added (experimental) CoreAudio driver
135 persson 1888 - applied old fixes to the ASIO driver that were included in the
136     previous binary release but accidentally never committed to CVS
137     (fixes #117)
138 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
139     win64)
140 persson 1895 - VST: added support for sample rate and buffer size changes
141     - VST: close editor (Fantasia) when the VST is removed
142 persson 1908 - VST: avoid opening Fantasia more than once for each VST instance

150     AudioChannel::CopyTo() methods using GCC vector exensions
151     (if available)
152 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
153     exception when getting parameters from a disconnected device
154 schoenebeck 1599
155 persson 1651 * MIDI driver:
156     - added JACK MIDI driver
157 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
158     want to (mis)use it for some purpose ("fixed" in all current MIDI
159     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
160 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
161 persson 1887 CoreMidi or AU
162 persson 1889 - fixed mingw-w64 compilation error in MME driver
163 persson 1924 - made program change handling in MIDI thread real-time safe by
164     moving the logic to a non-RT thread

166 persson 1651
167 schoenebeck 1604 * instruments database:
168 iliev 1603 - avoid time consuming samples scanning when adding instruments
169     to the instruments database
170 iliev 1727 - added support for handling lost files in the instruments database

172     in the instruments database
173     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
174 persson 1908 - work-around for missing fnmatch function on Windows to make
175     instrument database compilable
176 schoenebeck 1930 - added instrument database support on Windows
177     works with both standalone mode and VST plugin.
178     the instruments DB file is located in
179     %USERPROFILE%\.linuxsampler\instruments.db which allows different
180     databases for each windows user
181     if no DB is present it automatically creates the .linuxsampler subdir
182     and then creates an empty DB
183 persson 1943 - fixed recursive import, which was broken on Windows
184 iliev 1603
185 persson 1644 * Gigasampler format engine:
186     - fixed a memory leak that could happen when a channel was deleted
187     while notes were playing
188 persson 1646 - made it possible to load an instrument even if the audio thread
189     isn't running
190 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
191     enough for piano gigs with pedal noise samples
192 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
193     respective FX send MIDI controller was used
194 schoenebeck 1724 - added support for GM global device volume SysEx message
195 schoenebeck 1762 (can be selected at compile time to either apply globally to the
196     whole sampler [default] or only to the sampler channels that are
197     connected to the respective MIDI input port the SysEx message arrived
198     on)
199 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
200     sometimes wrongly killed in the same buffer, causing no sound to
201     be played
202 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
203     which is usally used to switch a part between chromatic sounds and
204     drumkit sounds (as opposed to their common default setting of MIDI
205     part 10 being a drumkit part and all other ones chromatic parts), in
206     LS however one can switch between the first 16 MIDI instrument maps
207     defined for the sampler
208 persson 1764 - made it possible to create multiple sample channels even if the
209     audio thread isn't running
210 persson 1844 - fixed crash when removing channel with active voices (#116)
211 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
212     un-cache the respective sample if it's really not used by any
213     sampler engine anymore
214     - re-cache samples in case they were changed by an instrument editor,
215     e.g. when a sample was added while playing (#82)
216 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
217     same time stamp as the voice's note-on event and occured both in the
218     same audio fragment cycle (fixes bug #112)
219 persson 1858 - added support for the "fine tune" and "pitch bend range"
220     instrument-level gig parameters
221     - fixed minor artifacts in pitch bend handling
222 schoenebeck 1860 - added support for GS Reset SysEx message
223 persson 1862 - allow gig files to use unlimited downward pitch shifting
224     - added a limit check for upward pitch shifting
225 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
226     note was silent
227 persson 1923 - fixed crash happening when a pitch bend event arrived at the
228     same time a new instrument was loading
229 persson 1644
230 schoenebeck 1687 * LSCP server:
231     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
232     react on MIDI data arriving on certain sampler channels (so far only
233     Note-On and Note-Off events are sent via this LSCP event)
234 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
235     react on MIDI data arriving on certain MIDI input devices (so far only
236     Note-On and Note-Off events are sent via this LSCP event)
237 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
238     SET DB_INSTRUMENT FILE_PATH
239 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
240     frontends to send MIDI messages to specific sampler channel
241     - added two additional fields to GET FILE INSTRUMENT INFO command -
242     KEY_BINDINGS and KEYSWITCH_BINDINGS
243 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
244     was incorrect
245 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
246 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
247     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
248     be triggered respectively
249     - added new LSCP command "SET STREAMS" to globally alter the maximum
250     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
251     which will be triggered respectively
252 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
253     a gigedit file dialog is opened)
254 iliev 1848 - close all connections when LSCPServer is deleted
255 iliev 1882 - hard close of all sockets on exit
256 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
257     driver
258 schoenebeck 1687
259 iliev 1761 * Bug fixes:
260     - fixed a crash which occurs when removing a sampler channel waiting
261     to start instrument loading after another channel
262 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
263     instrument loading in progress (bug #113)
264 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
265     instrument with PERSISTENT load mode
266 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
267     - fixed memory leaks when issuing the following LSCP commands:
268     GET AUDIO_OUTPUT_DRIVER INFO
269     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
270     GET MIDI_INPUT_DRIVER INFO
271     GET MIDI_INPUT_DRIVER_PARAMETER INFO
272     - fixed possible compilation error when sqlite is not present
273 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
274 iliev 1847 - fixed crash when changing the audio output device of a sampler
275     channel with loaded instrument and start playing notes
276 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
277 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
278     PowerPC, which probably could cause crashes on that platform
279 persson 1889 - fixed a memory management error which could cause a crash when a
280     plugin was unloaded
281 persson 1896 - bugfix: two private structs had the same name, which could cause
282     problems if the linker chose the wrong constructor
283 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
284     Windows
285 iliev 1761
286    
287 schoenebeck 1560 Version 0.5.1 (6 December 2007)
288 schoenebeck 1454
289     * packaging changes:
290     - added autoconf checks for pthread library
291     - added autoconf check for pthread bug found on certain NPTL-enabled
292     glibc versions (see Gentoo bug report #194076)
293 senoner 1502 - added autoconf checks for MS Windows
294 schoenebeck 1454
295 persson 1455 * general changes:
296     - bugfix: the thread used by an editor plugin didn't die when the
297     editor closed
298 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
299     out all the space. operator--() did not apply size_mask after
300     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
301     order to avoid problems with the _NonVolatileReader functions.
302     - bugfix: Stream.h: added a missing divide by BytesPerSample in
303     GetWriteSpace(). Since this function is currently only used in
304     the stream's qsort() compare function, it didn't trigger any
305     bugs.
306     - Resampler.h, Synthesizer.h: cubic interpolation now works in
307     24bit mode too. Faster method to read 24bit words on little
308     endian machines (x86): replaced 3 byte reads + shifts with a 1
309     unaligned 32bit read and shift
310     - experimental support for MS Windows (MIDI input via MME, AUDIO
311     output via ASIO)
312     - made handling of SIGINT signal (Ctrl-C) a bit more robust
313 iliev 1541 - support for monitoring the total number of active disk streams
314     (new LSCP commands: GET TOTAL_STREAM_COUNT,
315     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
316 persson 1455
317 senoner 1500 * AUDIO driver:
318 persson 1534 - added Windows ASIO low latency audio driver
319 senoner 1500
320 senoner 1485 * MIDI driver:
321 schoenebeck 1495 - added MME Windows MIDI driver
322 senoner 1485
323 schoenebeck 1471 * LSCP server:
324     - added support for Windows style path / filenames, however with
325     forward slash path separators instead of backslash
326     (i.e. "C:/foo/bar.gig")
327 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
328     apostrophes as well
329 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
330     "LIST FILE INSTRUMENTS <file>" and
331     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
332     about an arbitrary instrument file on the system where the sampler is
333     running on
334 schoenebeck 1471
335 schoenebeck 1424 Version 0.5.0 (15 October 2007)
336 schoenebeck 947
337 schoenebeck 1065 * packaging changes:
338 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
339     API header files anymore
340 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
341     the Doxygen API documentation (explicitly listed in Doxyfile.in)
342 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
343     capable to execute our autoconf environment, thus no need anymore
344     to maintain the compile time configuration file (osx/version.h) for
345     OSX manually (patch by Toshi Nagata)
346 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
347     parameters
348 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
349     C++ API header files, all implementation internal global definitions
350     are now in global_private.h
351     - atomic.h is not exposed to the C++ API anymore
352     - no need to include config.h anymore for using LS's API header files
353     - fixed warnings in API doc generation
354 schoenebeck 1065
355 schoenebeck 947 * general changes:
356     - replaced the old, confusing MIDI program change mechanism by a
357     flexible MIDI instrument mapper which allows to map arbitrary
358 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
359 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
360     loaded on the respective channel when such MIDI program change
361     messages arrive, beside that, each entry allows to define a life-time
362     strategy for the instrument, so the user can define whether the
363     instrument should i.e. be permanently loaded (to be able to switch
364     quickly among sounds) or i.e. loaded just on demand when the
365     respective program change arrives (to safe RAM space), as well as a
366     global volume factor for each entry, so the user can adjust the volume
367     dynamic of his mapped instrument collection without having to modify
368 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
369     MIDI instrument maps and assign each sampler channel individually
370     a certain map, so that i.e. separation of normal instruments and
371     drumkits is possible
372 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
373     MIDI instrument maps, MIDI instruments, FX sends, global volume.
374 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
375     due to a constant size RingBuffer FIFO which is now replaced by a
376     dynamic (unlimited) size std::list FIFO
377 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
378     output channels for being processed by external effect processors
379     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
380     controllers
381 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
382 iliev 1130 - Implemented new, improved notification system
383 schoenebeck 1149 - fixed compilation errors regarding OSX
384     (patch by Toshi Nagata)
385 iliev 1161 - implemented instruments database
386 iliev 1345 - added support for escape sequences to the instruments database
387 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
388     within the sampler's process (by using instrument editor plugins),
389     you'll notice the new "Registered instrument editors:" message on
390 schoenebeck 1407 startup, added a new LSCP command:
391     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
392 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
393     given sampler channel, the plugin path can be overridden at compile
394     time with ./configure --enable-plugin-dir=/some/dir
395 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
396     in the sampler's process to safely edit instruments while playing
397     without a crash (hopefully) by either suspending single regions
398     wherever possible or if unavoidable whole engine(s)
399 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
400     policy and priority on thread level, set a minimum stack size for
401     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
402     threads simply inherited properties of starting thread instead of
403     setting their own policy and priority
404 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
405     main process did not wait for the stack trace process to finish
406     its output
407 persson 1248 - fixed some minor memory leaks
408 schoenebeck 1259 - reenabled assembly features support, at the moment only for
409     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
410 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
411     register, to avoid relocations in the text segment at runtime)
412 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
413 schoenebeck 947
414     * MIDI driver:
415     - dispatch bank select (MSB and LSB) messages
416    
417 schoenebeck 1049 * audio driver:
418     - the ALSA audio output driver parameters now reflect the correct
419     parameter value ranges for the respective selected sound card
420     (patch by Till Wimmer, a bit fixed and extended)
421    
422 persson 951 * Gigasampler format engine:
423     - if a filter is used and EG2 finishes before EG1, let the voice
424     die when EG2 has finished (this fixes a problem with clicks and
425     voice starvation for some gigs)
426 persson 1038 - playback is no longer disabled during instrument loading
427     - all notes playing on a channel that changes its instrument keep
428     playing with the old instrument until they get a note off
429     command
430 persson 1039 - EG fix: a release value of zero could cause noises or crash
431 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
432 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
433     above max sustain level, which means that there is a decay phase
434     even if sustain is 100%
435 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
436     noises or crashes
437 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
438 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
439     supplied to the configure script (fixes #46)
440 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
441     instead of a fix value
442 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
443     127 (solo mode) only kill voices if the respective mode really
444     changed
445 persson 951
446 schoenebeck 1244 * LSCP server:
447     - fixed compile time error for old Bison versions
448     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
449 schoenebeck 1245 - parser now supports extended ASCII character set
450     (up to ASCII code 255, i.e. includes now umlauts and accents)
451     - filename arguments in LSCP commands now allow to use escape
452     sequences, that is directly literal as one of: \', \", \\, \n, \r,
453     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
454     code value like \xf2) (fixes bug #24)
455 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
456     least one of their text-based parameters (i.e. name, description):
457     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
458     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
459     "SET DB_INSTRUMENT_DIRECTORY NAME",
460     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
461     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
462     "FIND DB_INSTRUMENT_DIRECTORIES"
463 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
464     occured, the unexpected character and the actually expected, possible
465     character(s), the latter only if less than 5 possibilities)
466 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
467     settings
468 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
469     of strings were treated as being one string containing commas
470     (fixes #57)
471 schoenebeck 1244
472 iliev 959 * Bug fixes:
473     - fixed crash occurring on certain LSCP scripts (Bug 39)
474 persson 1038 - another thread safety fix for lscp "load engine" and "set
475     channel audio output device"
476 iliev 1283 - fixed a crash which occurs when reassigning the same engine
477     on a sampler channel with connected MIDI device
478 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
479     device connected to a sampler channel to number less then or equal
480     to the index of the port to which the sampler channel is connected.
481 iliev 1296 - The previous bindings were not been disconnected when altering
482     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
483     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
484 iliev 1297 - The active stream/voice count statistic was incorrect.
485 iliev 1298 - notification events were not been sent for some sampler
486     channel changes
487 iliev 1305 - added default min and max values to restrict the number of allowed
488     audio output channels and MIDI input ports
489 iliev 1306 - the connection to the PCM interface is now closed when destroying
490     an audio output device
491 schoenebeck 1332 - files with slash in their path or filename could not be loaded
492 iliev 959
493 schoenebeck 1221 * test cases:
494     - updated and fixed (haven't been touched in a while)
495    
496 schoenebeck 937 Version 0.4.0 (24 November 2006)
497 persson 696
498 schoenebeck 697 * packaging changes:
499 capela 868 - changed deprecated copyright attribute to license; added ldconfig
500     to post-(un)install steps; added devel package for liblinuxsampler;
501     to linuxsampler.spec (RPM)
502 schoenebeck 697 - install necessary development header files for allowing 3rd party
503     applications to link against liblinuxsampler
504     - liblinuxsampler's API documentation can be generated with 'make docs'
505     (Doxygen required)
506 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
507     implementation (currently either an integer math solution or a
508     di-harmonic approximation), automatic detection can be overriden
509     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
510     configure script argument though (mandatory for cross-compilation)
511 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
512     provided some on his own (as CXXFLAGS)
513 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
514     messages
515 schoenebeck 852 - added compile time options to allow disabling the various audio and
516     MIDI drivers
517 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
518     (patch by Ebrahim Mayat)
519 schoenebeck 697
520 persson 696 * Gigasampler format engine:
521 schoenebeck 738 - extensive synthesis optimization
522     (reimplementation of EGs and LFO(s), removed synthesis parameter
523     prerendering and the synthesis parameter matrix in general, splitting
524     each audio fragment into subfragments now where each subfragment uses
525 persson 830 constant pitch and filter coefficients. The volume coefficient is
526     linearly interpolated inside a subfragment, unless
527     --disable-interpolate-volume is set.)
528 persson 696 - fine tuning of the EG modulation parameters
529 persson 729 - improved filter cutoff calculation by adding support for the
530     following gig parameters: Cutoff freq (used when no cutoff
531     controller is defined), Control invert, Minimum cutoff, Velocity
532 persson 791 curve and Velocity range. The keyboard tracking now scales
533     cutoff frequency instead of resonance.
534 persson 877 - added support for gig parameter Resonance.
535 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
536 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
537     which can be overridden with --enable-global-attenuation
538 persson 783 - EG fixes: made the length of "attack hold" stage more
539     accurate. Release stage can now start before attack stage
540 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
541     time now has a minimal value to prevent clicks.
542 persson 799 - fixed pitch changes larger than one octave
543 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
544     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
545     all modes can be altered via standard GM messages, that is CC5 for
546     altering portamento time, CC65 for enabling / disabling portamento
547     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
548 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
549     parameter) and crossfade
550 persson 831 - added support for the "attenuation controller threshold" gig
551     parameter
552 persson 832 - added smoothing of volume changes caused by control change
553     messages
554 persson 865 - sample loop parameters are now taken from the DimensionRegion
555     instead of the wave chunk
556     - fixed keyswitching for v3 gigs with a number of keyswitch splits
557     not equal to a power of two
558 persson 877 - reimplementation of the filter algorithm. The new filter is more
559     accurate and supports all gig filter types, including bandreject
560     and lowpass turbo.
561 persson 903 - real support for 24 bit samples - samples are not truncated to
562     16 bits anymore
563     - support for aftertouch (channel pressure, not polyphonic
564     aftertouch)
565 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
566     amplifying from 0)
567 persson 696
568 schoenebeck 711 * LSCP server:
569     - fixed application exit on broken pipe error (fixes bug #20)
570 iliev 793 - fixed the notification messages delay due to lack of
571     network activity (fixes bug #26)
572 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
573     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
574 schoenebeck 711
575 schoenebeck 838 * audio driver:
576     - added aRts audio output driver (by no means RT safe)
577    
578 schoenebeck 775 * MIDI driver:
579     - fixed legacy sysex code which caused dispatching of MIDI SysEx
580     messages several times instead of once
581 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
582     for events (i.e. for offline rendering based MIDI drivers)
583 persson 922 - added checks for bad MIDI data
584 schoenebeck 775
585 schoenebeck 900 * linuxsampler application:
586     - show available sampler engine types on startup
587    
588 schoenebeck 705 * general changes:
589     - support for muting sampler channels and solo mode of the same, two new
590     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
591     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
592     introduced for this, the behavior is the same like on a mixer console
593 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
594     --enable-process-muted-channels which can be used to enable the
595     processing of muted channels.
596 iliev 777 - support for sostenuto pedal
597 iliev 779 - support for monitoring the total number of active voices
598 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
599     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
600 persson 835 - fixed some memory management errors
601 persson 841 - fixed some concurrency problems that could lead to crashes when
602     LSCP commands were executed
603 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
604     sampler channel (fixes bug #36)
605 schoenebeck 705
606 schoenebeck 692 Version 0.3.3 (15 July 2005)
607 schoenebeck 686
608     * packaging changes:
609     - fixed compilation with gcc 4.0
610    
611 schoenebeck 687 * Gigasampler format engine:
612     - LFO preprocessing was performed even though the respective LFO was
613     disabled by the instrument patch (minor efficiency fix)
614 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
615     for volume ramp downs in the same fragment (needed for current voice
616     stealing implementation) then simply inform the user with a warning
617     about possible click sounds and reduce the volume ramp down
618     appropriately instead of cancelling the audio device connection
619 schoenebeck 687
620 schoenebeck 677 Version 0.3.2 (24 June 2005)
621 schoenebeck 609
622     * packaging changes:
623     - updated autotools build files to compile on OS X
624     (conditional compilation of CoreMIDI and MidiShare drivers)
625 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
626     './configure --disable-asm' (definitely not recommended)
627 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
628     - require automake (>= 1.5) for 'make -f Makefile.cvs'
629     (due to 'dist-bzip2' automake option)
630 schoenebeck 649
631     * Gigasampler format engine:
632     - support for the gig parameters for "release velocity response" curves
633     - fine tuning of the EGADSR envelope
634     - volume of release triggered samples now depends on note-on velocity,
635     note length and gig parameter "release trigger decay" instead of
636     note-off velocity.
637 schoenebeck 663 - revised voice stealing
638     (fixes crash and endless loop caused by voice stealing)
639 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
640 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
641     instead of when the respective voice is actually launched
642     (fixes undefined behavior if stolen voices belonged to a key group -
643     this case was followed by a "killed voice survived" error message)
644 schoenebeck 669 - fixed minor issue with null/silence samples
645     (those stole voices even though they don't need a voice at all which
646     resulted in "voice stealing didn't work out" messages)
647 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
648     instrument or audio output device change
649 schoenebeck 654
650 schoenebeck 620 * LSCP server:
651 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
652 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
653 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
654 schoenebeck 609
655 schoenebeck 668 * linuxsampler application:
656     - added command line parameters --lscp-addr and --lscp-port to override
657     default IP address and port of LSCP server
658    
659 schoenebeck 579 Version 0.3.1 (24 May 2005)
660    
661     * initial release
