* Introduced support for optional environment variable
  "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
  where the sampler shall look for instrument editor plugins
  (patch by Luis Garrido, slightly modified).
* bumped version to 1.0.0.cvs3

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    
23 schoenebeck 2047 * SoundFont format engine:
24 iliev 2012 - Initial implementation (not usable yet)
25    
26     * Host plugins:
27 schoenebeck 1993 - AU bugfix: failed to destroy its audio/MIDI devices
28 iliev 1994 - Listen to all interfaces on Mac OS X (INADDR_ANY)
29 persson 2045 - VST bugfix: If the host called resume() before and after
30     changing sample rate or block size, the number of channels was
31     incorrectly set to two. This caused silence in Cubase 5.
32 schoenebeck 1993
33     * MIDI driver:
34     - ALSA MIDI driver supports now "NAME" device parameter, for overriding
35     the ALSA sequencer client name

45 schoenebeck 1599
46 schoenebeck 1639 * packaging changes:
47     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
48     causing e.g. the libgig test to fail when
49     "./configure --disable-jack-driver" was used
50     (patch by Alexis Ballier)

59 schoenebeck 1928 directory of liblinuxsampler dll (look in the same directory and one
60     directory above)
61 persson 1899 - configure script fix: removed unconditional use of SSE
62 persson 1923 - fixed building with sqlite installed in a non-standard directory

65 schoenebeck 1639
66 schoenebeck 1601 * general changes:

68     load as we used a non-portable Linux specific struct field
69     (fixes bug #70, patch by Ronald Baljeu)
70 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
71     plugin DLL on Windows systems failed
72 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded
73     - optimized the SynchronizedConfig class so it doesn't wait
74     unnecessarily long after an update
75 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
76     events (e.g. to highlight the pressed keys on the virtual keyboard
77     of gigedit)
78 schoenebeck 1659 - added support for triggering notes by instrument editors (see above)
79 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
80 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation
81     is only used by very few systems, most pick the int math
82     implementation, which is usually faster)

84 persson 1777 - experimental support for running LinuxSampler as a DSSI, LV2 and
85     VST plugin

91 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
92 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
93     be switched on by command line option "--stacktrace" (the automatic
94     stacktrace mechanism seems to be broken on most systems at the moment)
95 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
96     a pointer to the launched InstrumentEditor object
97 schoenebeck 1876 - added optional 3rd party user data parameter for following
98     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
99     InstrumentEditor::Launch(),
100     InstrumentManager::LaunchInstrumentEditor()
101 persson 1887 - theoretical fix: made SynchronizedConfig follow C++0x memory

107 schoenebeck 1601
108 schoenebeck 1599 * audio driver:
109     - removed the nonsense audio channel constraint (which was hard coded to
110     max. 100 audio channels) for most audio drivers
111 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
112     opposed to the LSCP specs
113 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
114     reflected the wrong value

118 persson 1748 jack_client_new
119 iliev 1829 - added (experimental) CoreAudio driver
120 persson 1888 - applied old fixes to the ASIO driver that were included in the
121     previous binary release but accidentally never committed to CVS
122     (fixes #117)
123 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
124     win64)
125 persson 1895 - VST: added support for sample rate and buffer size changes
126     - VST: close editor (Fantasia) when the VST is removed
127 persson 1908 - VST: avoid opening Fantasia more than once for each VST instance

135     AudioChannel::CopyTo() methods using GCC vector exensions
136     (if available)
137 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
138     exception when getting parameters from a disconnected device
139 schoenebeck 1599
140 persson 1651 * MIDI driver:
141     - added JACK MIDI driver
142 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
143     want to (mis)use it for some purpose ("fixed" in all current MIDI
144     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
145 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
146 persson 1887 CoreMidi or AU
147 persson 1889 - fixed mingw-w64 compilation error in MME driver
148 persson 1924 - made program change handling in MIDI thread real-time safe by
149     moving the logic to a non-RT thread
150 persson 1951 - fixed minor memory leak in ALSA driver
151 persson 1651
152 schoenebeck 1604 * instruments database:
153 iliev 1603 - avoid time consuming samples scanning when adding instruments
154     to the instruments database
155 iliev 1727 - added support for handling lost files in the instruments database
156 iliev 1781 - Implemented option for adding instruments in separate directories
157     in the instruments database
158     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
159 persson 1908 - work-around for missing fnmatch function on Windows to make
160     instrument database compilable
161 schoenebeck 1930 - added instrument database support on Windows
162     works with both standalone mode and VST plugin.
163     the instruments DB file is located in
164     %USERPROFILE%\.linuxsampler\instruments.db which allows different
165     databases for each windows user
166     if no DB is present it automatically creates the .linuxsampler subdir
167     and then creates an empty DB
168 persson 1943 - fixed recursive import, which was broken on Windows
169 iliev 1603
170 persson 1644 * Gigasampler format engine:
171     - fixed a memory leak that could happen when a channel was deleted
172     while notes were playing
173 persson 1646 - made it possible to load an instrument even if the audio thread
174     isn't running
175 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
176     enough for piano gigs with pedal noise samples
177 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
178     respective FX send MIDI controller was used
179 schoenebeck 1724 - added support for GM global device volume SysEx message
180 schoenebeck 1762 (can be selected at compile time to either apply globally to the
181     whole sampler [default] or only to the sampler channels that are
182     connected to the respective MIDI input port the SysEx message arrived
183     on)
184 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
185     sometimes wrongly killed in the same buffer, causing no sound to
186     be played
187 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
188     which is usally used to switch a part between chromatic sounds and
189     drumkit sounds (as opposed to their common default setting of MIDI
190     part 10 being a drumkit part and all other ones chromatic parts), in
191     LS however one can switch between the first 16 MIDI instrument maps
192     defined for the sampler
193 persson 1764 - made it possible to create multiple sample channels even if the
194     audio thread isn't running
195 persson 1844 - fixed crash when removing channel with active voices (#116)
196 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
197     un-cache the respective sample if it's really not used by any
198     sampler engine anymore
199     - re-cache samples in case they were changed by an instrument editor,
200     e.g. when a sample was added while playing (#82)
201 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
202     same time stamp as the voice's note-on event and occured both in the
203     same audio fragment cycle (fixes bug #112)
204 persson 1858 - added support for the "fine tune" and "pitch bend range"
205     instrument-level gig parameters
206     - fixed minor artifacts in pitch bend handling
207 schoenebeck 1860 - added support for GS Reset SysEx message
208 persson 1862 - allow gig files to use unlimited downward pitch shifting
209     - added a limit check for upward pitch shifting
210 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
211     note was silent
212 persson 1923 - fixed crash happening when a pitch bend event arrived at the
213     same time a new instrument was loading
214 persson 1644
215 schoenebeck 1687 * LSCP server:
216     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
217     react on MIDI data arriving on certain sampler channels (so far only
218     Note-On and Note-Off events are sent via this LSCP event)
219 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
220     react on MIDI data arriving on certain MIDI input devices (so far only
221     Note-On and Note-Off events are sent via this LSCP event)
222 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
223     SET DB_INSTRUMENT FILE_PATH
224 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
225     frontends to send MIDI messages to specific sampler channel
226     - added two additional fields to GET FILE INSTRUMENT INFO command -
227     KEY_BINDINGS and KEYSWITCH_BINDINGS
228 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
229     was incorrect
230 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
231 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
232     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
233     be triggered respectively
234     - added new LSCP command "SET STREAMS" to globally alter the maximum
235     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
236     which will be triggered respectively
237 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
238     a gigedit file dialog is opened)
239 iliev 1848 - close all connections when LSCPServer is deleted
240 iliev 1882 - hard close of all sockets on exit
241 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
242     driver
243 schoenebeck 1687
244 iliev 1761 * Bug fixes:
245     - fixed a crash which occurs when removing a sampler channel waiting
246     to start instrument loading after another channel
247 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
248     instrument loading in progress (bug #113)
249 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
250     instrument with PERSISTENT load mode
251 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
252     - fixed memory leaks when issuing the following LSCP commands:
253     GET AUDIO_OUTPUT_DRIVER INFO
254     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
255     GET MIDI_INPUT_DRIVER INFO
256     GET MIDI_INPUT_DRIVER_PARAMETER INFO
257     - fixed possible compilation error when sqlite is not present
258 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
259 iliev 1847 - fixed crash when changing the audio output device of a sampler
260     channel with loaded instrument and start playing notes
261 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
262 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
263     PowerPC, which probably could cause crashes on that platform
264 persson 1889 - fixed a memory management error which could cause a crash when a
265     plugin was unloaded
266 persson 1896 - bugfix: two private structs had the same name, which could cause
267     problems if the linker chose the wrong constructor
268 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
269     Windows
270 iliev 1761
271    
272 schoenebeck 1560 Version 0.5.1 (6 December 2007)
273 schoenebeck 1454
274     * packaging changes:
275     - added autoconf checks for pthread library
276     - added autoconf check for pthread bug found on certain NPTL-enabled
277     glibc versions (see Gentoo bug report #194076)
278 senoner 1502 - added autoconf checks for MS Windows
279 schoenebeck 1454
280 persson 1455 * general changes:
281     - bugfix: the thread used by an editor plugin didn't die when the
282     editor closed
283 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
284     out all the space. operator--() did not apply size_mask after
285     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
286     order to avoid problems with the _NonVolatileReader functions.
287     - bugfix: Stream.h: added a missing divide by BytesPerSample in
288     GetWriteSpace(). Since this function is currently only used in
289     the stream's qsort() compare function, it didn't trigger any
290     bugs.
291     - Resampler.h, Synthesizer.h: cubic interpolation now works in
292     24bit mode too. Faster method to read 24bit words on little
293     endian machines (x86): replaced 3 byte reads + shifts with a 1
294     unaligned 32bit read and shift
295     - experimental support for MS Windows (MIDI input via MME, AUDIO
296     output via ASIO)
297     - made handling of SIGINT signal (Ctrl-C) a bit more robust
298 iliev 1541 - support for monitoring the total number of active disk streams
299     (new LSCP commands: GET TOTAL_STREAM_COUNT,
300     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
301 persson 1455
302 senoner 1500 * AUDIO driver:
303 persson 1534 - added Windows ASIO low latency audio driver
304 senoner 1500
305 senoner 1485 * MIDI driver:
306 schoenebeck 1495 - added MME Windows MIDI driver
307 senoner 1485
308 schoenebeck 1471 * LSCP server:
309     - added support for Windows style path / filenames, however with
310     forward slash path separators instead of backslash
311     (i.e. "C:/foo/bar.gig")
312 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
313     apostrophes as well
314 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
315     "LIST FILE INSTRUMENTS <file>" and
316     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
317     about an arbitrary instrument file on the system where the sampler is
318     running on
319 schoenebeck 1471
320 schoenebeck 1424 Version 0.5.0 (15 October 2007)
321 schoenebeck 947
322 schoenebeck 1065 * packaging changes:
323 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
324     API header files anymore
325 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
326     the Doxygen API documentation (explicitly listed in Doxyfile.in)
327 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
328     capable to execute our autoconf environment, thus no need anymore
329     to maintain the compile time configuration file (osx/version.h) for
330     OSX manually (patch by Toshi Nagata)
331 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
332     parameters
333 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
334     C++ API header files, all implementation internal global definitions
335     are now in global_private.h
336     - atomic.h is not exposed to the C++ API anymore
337     - no need to include config.h anymore for using LS's API header files
338     - fixed warnings in API doc generation
339 schoenebeck 1065
340 schoenebeck 947 * general changes:
341     - replaced the old, confusing MIDI program change mechanism by a
342     flexible MIDI instrument mapper which allows to map arbitrary
343 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
344 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
345     loaded on the respective channel when such MIDI program change
346     messages arrive, beside that, each entry allows to define a life-time
347     strategy for the instrument, so the user can define whether the
348     instrument should i.e. be permanently loaded (to be able to switch
349     quickly among sounds) or i.e. loaded just on demand when the
350     respective program change arrives (to safe RAM space), as well as a
351     global volume factor for each entry, so the user can adjust the volume
352     dynamic of his mapped instrument collection without having to modify
353 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
354     MIDI instrument maps and assign each sampler channel individually
355     a certain map, so that i.e. separation of normal instruments and
356     drumkits is possible
357 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
358     MIDI instrument maps, MIDI instruments, FX sends, global volume.
359 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
360     due to a constant size RingBuffer FIFO which is now replaced by a
361     dynamic (unlimited) size std::list FIFO
362 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
363     output channels for being processed by external effect processors
364     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
365     controllers
366 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
367 iliev 1130 - Implemented new, improved notification system
368 schoenebeck 1149 - fixed compilation errors regarding OSX
369     (patch by Toshi Nagata)
370 iliev 1161 - implemented instruments database
371 iliev 1345 - added support for escape sequences to the instruments database
372 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
373     within the sampler's process (by using instrument editor plugins),
374     you'll notice the new "Registered instrument editors:" message on
375 schoenebeck 1407 startup, added a new LSCP command:
376     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
377 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
378     given sampler channel, the plugin path can be overridden at compile
379     time with ./configure --enable-plugin-dir=/some/dir
380 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
381     in the sampler's process to safely edit instruments while playing
382     without a crash (hopefully) by either suspending single regions
383     wherever possible or if unavoidable whole engine(s)
384 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
385     policy and priority on thread level, set a minimum stack size for
386     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
387     threads simply inherited properties of starting thread instead of
388     setting their own policy and priority
389 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
390     main process did not wait for the stack trace process to finish
391     its output
392 persson 1248 - fixed some minor memory leaks
393 schoenebeck 1259 - reenabled assembly features support, at the moment only for
394     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
395 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
396     register, to avoid relocations in the text segment at runtime)
397 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
398 schoenebeck 947
399     * MIDI driver:
400     - dispatch bank select (MSB and LSB) messages
401    
402 schoenebeck 1049 * audio driver:
403     - the ALSA audio output driver parameters now reflect the correct
404     parameter value ranges for the respective selected sound card
405     (patch by Till Wimmer, a bit fixed and extended)
406    
407 persson 951 * Gigasampler format engine:
408     - if a filter is used and EG2 finishes before EG1, let the voice
409     die when EG2 has finished (this fixes a problem with clicks and
410     voice starvation for some gigs)
411 persson 1038 - playback is no longer disabled during instrument loading
412     - all notes playing on a channel that changes its instrument keep
413     playing with the old instrument until they get a note off
414     command
415 persson 1039 - EG fix: a release value of zero could cause noises or crash
416 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
417 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
418     above max sustain level, which means that there is a decay phase
419     even if sustain is 100%
420 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
421     noises or crashes
422 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
423 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
424     supplied to the configure script (fixes #46)
425 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
426     instead of a fix value
427 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
428     127 (solo mode) only kill voices if the respective mode really
429     changed
430 persson 951
431 schoenebeck 1244 * LSCP server:
432     - fixed compile time error for old Bison versions
433     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
434 schoenebeck 1245 - parser now supports extended ASCII character set
435     (up to ASCII code 255, i.e. includes now umlauts and accents)
436     - filename arguments in LSCP commands now allow to use escape
437     sequences, that is directly literal as one of: \', \", \\, \n, \r,
438     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
439     code value like \xf2) (fixes bug #24)
440 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
441     least one of their text-based parameters (i.e. name, description):
442     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
443     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
444     "SET DB_INSTRUMENT_DIRECTORY NAME",
445     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
446     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
447     "FIND DB_INSTRUMENT_DIRECTORIES"
448 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
449     occured, the unexpected character and the actually expected, possible
450     character(s), the latter only if less than 5 possibilities)
451 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
452     settings
453 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
454     of strings were treated as being one string containing commas
455     (fixes #57)
456 schoenebeck 1244
457 iliev 959 * Bug fixes:
458     - fixed crash occurring on certain LSCP scripts (Bug 39)
459 persson 1038 - another thread safety fix for lscp "load engine" and "set
460     channel audio output device"
461 iliev 1283 - fixed a crash which occurs when reassigning the same engine
462     on a sampler channel with connected MIDI device
463 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
464     device connected to a sampler channel to number less then or equal
465     to the index of the port to which the sampler channel is connected.
466 iliev 1296 - The previous bindings were not been disconnected when altering
467     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
468     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
469 iliev 1297 - The active stream/voice count statistic was incorrect.
470 iliev 1298 - notification events were not been sent for some sampler
471     channel changes
472 iliev 1305 - added default min and max values to restrict the number of allowed
473     audio output channels and MIDI input ports
474 iliev 1306 - the connection to the PCM interface is now closed when destroying
475     an audio output device
476 schoenebeck 1332 - files with slash in their path or filename could not be loaded
477 iliev 959
478 schoenebeck 1221 * test cases:
479     - updated and fixed (haven't been touched in a while)
480    
481 schoenebeck 937 Version 0.4.0 (24 November 2006)
482 persson 696
483 schoenebeck 697 * packaging changes:
484 capela 868 - changed deprecated copyright attribute to license; added ldconfig
485     to post-(un)install steps; added devel package for liblinuxsampler;
486     to linuxsampler.spec (RPM)
487 schoenebeck 697 - install necessary development header files for allowing 3rd party
488     applications to link against liblinuxsampler
489     - liblinuxsampler's API documentation can be generated with 'make docs'
490     (Doxygen required)
491 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
492     implementation (currently either an integer math solution or a
493     di-harmonic approximation), automatic detection can be overriden
494     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
495     configure script argument though (mandatory for cross-compilation)
496 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
497     provided some on his own (as CXXFLAGS)
498 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
499     messages
500 schoenebeck 852 - added compile time options to allow disabling the various audio and
501     MIDI drivers
502 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
503     (patch by Ebrahim Mayat)
504 schoenebeck 697
505 persson 696 * Gigasampler format engine:
506 schoenebeck 738 - extensive synthesis optimization
507     (reimplementation of EGs and LFO(s), removed synthesis parameter
508     prerendering and the synthesis parameter matrix in general, splitting
509     each audio fragment into subfragments now where each subfragment uses
510 persson 830 constant pitch and filter coefficients. The volume coefficient is
511     linearly interpolated inside a subfragment, unless
512     --disable-interpolate-volume is set.)
513 persson 696 - fine tuning of the EG modulation parameters
514 persson 729 - improved filter cutoff calculation by adding support for the
515     following gig parameters: Cutoff freq (used when no cutoff
516     controller is defined), Control invert, Minimum cutoff, Velocity
517 persson 791 curve and Velocity range. The keyboard tracking now scales
518     cutoff frequency instead of resonance.
519 persson 877 - added support for gig parameter Resonance.
520 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
521 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
522     which can be overridden with --enable-global-attenuation
523 persson 783 - EG fixes: made the length of "attack hold" stage more
524     accurate. Release stage can now start before attack stage
525 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
526     time now has a minimal value to prevent clicks.
527 persson 799 - fixed pitch changes larger than one octave
528 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
529     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
530     all modes can be altered via standard GM messages, that is CC5 for
531     altering portamento time, CC65 for enabling / disabling portamento
532     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
533 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
534     parameter) and crossfade
535 persson 831 - added support for the "attenuation controller threshold" gig
536     parameter
537 persson 832 - added smoothing of volume changes caused by control change
538     messages
539 persson 865 - sample loop parameters are now taken from the DimensionRegion
540     instead of the wave chunk
541     - fixed keyswitching for v3 gigs with a number of keyswitch splits
542     not equal to a power of two
543 persson 877 - reimplementation of the filter algorithm. The new filter is more
544     accurate and supports all gig filter types, including bandreject
545     and lowpass turbo.
546 persson 903 - real support for 24 bit samples - samples are not truncated to
547     16 bits anymore
548     - support for aftertouch (channel pressure, not polyphonic
549     aftertouch)
550 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
551     amplifying from 0)
552 persson 696
553 schoenebeck 711 * LSCP server:
554     - fixed application exit on broken pipe error (fixes bug #20)
555 iliev 793 - fixed the notification messages delay due to lack of
556     network activity (fixes bug #26)
557 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
558     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
559 schoenebeck 711
560 schoenebeck 838 * audio driver:
561     - added aRts audio output driver (by no means RT safe)
562    
563 schoenebeck 775 * MIDI driver:
564     - fixed legacy sysex code which caused dispatching of MIDI SysEx
565     messages several times instead of once
566 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
567     for events (i.e. for offline rendering based MIDI drivers)
568 persson 922 - added checks for bad MIDI data
569 schoenebeck 775
570 schoenebeck 900 * linuxsampler application:
571     - show available sampler engine types on startup
572    
573 schoenebeck 705 * general changes:
574     - support for muting sampler channels and solo mode of the same, two new
575     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
576     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
577     introduced for this, the behavior is the same like on a mixer console
578 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
579     --enable-process-muted-channels which can be used to enable the
580     processing of muted channels.
581 iliev 777 - support for sostenuto pedal
582 iliev 779 - support for monitoring the total number of active voices
583 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
584     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
585 persson 835 - fixed some memory management errors
586 persson 841 - fixed some concurrency problems that could lead to crashes when
587     LSCP commands were executed
588 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
589     sampler channel (fixes bug #36)
590 schoenebeck 705
591 schoenebeck 692 Version 0.3.3 (15 July 2005)
592 schoenebeck 686
593     * packaging changes:
594     - fixed compilation with gcc 4.0
595    
596 schoenebeck 687 * Gigasampler format engine:
597     - LFO preprocessing was performed even though the respective LFO was
598     disabled by the instrument patch (minor efficiency fix)
599 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
600     for volume ramp downs in the same fragment (needed for current voice
601     stealing implementation) then simply inform the user with a warning
602     about possible click sounds and reduce the volume ramp down
603     appropriately instead of cancelling the audio device connection
604 schoenebeck 687
605 schoenebeck 677 Version 0.3.2 (24 June 2005)
606 schoenebeck 609
607     * packaging changes:
608     - updated autotools build files to compile on OS X
609     (conditional compilation of CoreMIDI and MidiShare drivers)
610 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
611     './configure --disable-asm' (definitely not recommended)
612 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
613     - require automake (>= 1.5) for 'make -f Makefile.cvs'
614     (due to 'dist-bzip2' automake option)
615 schoenebeck 649
616     * Gigasampler format engine:
617     - support for the gig parameters for "release velocity response" curves
618     - fine tuning of the EGADSR envelope
619     - volume of release triggered samples now depends on note-on velocity,
620     note length and gig parameter "release trigger decay" instead of
621     note-off velocity.
622 schoenebeck 663 - revised voice stealing
623     (fixes crash and endless loop caused by voice stealing)
624 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
625 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
626     instead of when the respective voice is actually launched
627     (fixes undefined behavior if stolen voices belonged to a key group -
628     this case was followed by a "killed voice survived" error message)
629 schoenebeck 669 - fixed minor issue with null/silence samples
630     (those stole voices even though they don't need a voice at all which
631     resulted in "voice stealing didn't work out" messages)
632 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
633     instrument or audio output device change
634 schoenebeck 654
635 schoenebeck 620 * LSCP server:
636 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
637 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
638 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
639 schoenebeck 609
640 schoenebeck 668 * linuxsampler application:
641     - added command line parameters --lscp-addr and --lscp-port to override
642     default IP address and port of LSCP server
643    
644 schoenebeck 579 Version 0.3.1 (24 May 2005)
645    
646     * initial release
