2 schoenebeck 1599
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)

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 persson 1931 - when cross-compiling, don't try to create instruments.db
21     - fix for new mingw-w64 version, which has usleep
22 schoenebeck 1639
23 schoenebeck 1601 * general changes:
24     - bugfix: on some POSIX systems instrument editor plugins refused to
25     load as we used a non-portable Linux specific struct field
26     (fixes bug #70, patch by Ronald Baljeu)
27 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
28     plugin DLL on Windows systems failed
29 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded
30     - optimized the SynchronizedConfig class so it doesn't wait
31     unnecessarily long after an update
32 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
33     events (e.g. to highlight the pressed keys on the virtual keyboard
34     of gigedit)
35 schoenebeck 1659 - added support for triggering notes by instrument editors (see above)
36 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
37 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation
38     is only used by very few systems, most pick the int math
39     implementation, which is usually faster)
40 persson 1748 - fixes for audio drivers with varying buffer sizes
41 persson 1777 - experimental support for running LinuxSampler as a DSSI, LV2 and
42     VST plugin
43 iliev 1789 - notification events for stream/voice count statistics are now sent
44     only when there are actual changes
45 persson 1790 - added memory ordering constraints to improve stability on
46     multi-core and multi-cpu systems

48 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
49 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
50     be switched on by command line option "--stacktrace" (the automatic
51     stacktrace mechanism seems to be broken on most systems at the moment)
52 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
53     a pointer to the launched InstrumentEditor object
54 schoenebeck 1876 - added optional 3rd party user data parameter for following
55     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
56     InstrumentEditor::Launch(),
57     InstrumentManager::LaunchInstrumentEditor()
58 persson 1887 - theoretical fix: made SynchronizedConfig follow C++0x memory
59     model more strictly
60 persson 1895 - fixes for using large audio device buffers
61 persson 1951 - Windows: add the installation directory to the DLL search path
62     when loading an editor plugin (solves problems with VST and
63     gigedit on systems with other GTK versions installed)
64 schoenebeck 1601
65 schoenebeck 1599 * audio driver:
66     - removed the nonsense audio channel constraint (which was hard coded to
67     max. 100 audio channels) for most audio drivers
68 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
69     opposed to the LSCP specs
70 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
71     reflected the wrong value
72 persson 1644 - fixed a memory management bug in ASIO driver
73 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used

75 persson 1748 jack_client_new
76 iliev 1829 - added (experimental) CoreAudio driver
77 persson 1888 - applied old fixes to the ASIO driver that were included in the
78     previous binary release but accidentally never committed to CVS
79     (fixes #117)
80 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
81     win64)
82 persson 1895 - VST: added support for sample rate and buffer size changes
83     - VST: close editor (Fantasia) when the VST is removed
84 persson 1908 - VST: avoid opening Fantasia more than once for each VST instance
85     - VST: export main function as "main" on Linux too (fix for

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