  Windows

1 schoenebeck 1599 Version CVS HEAD (?)
2    
3 schoenebeck 1639 * packaging changes:
4     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
5     causing e.g. the libgig test to fail when
6     "./configure --disable-jack-driver" was used
7     (patch by Alexis Ballier)
8 persson 1713 - fixed compilation with gcc 4.3
9 persson 1792 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
10 persson 1794 - fixed configure so it detects x86_64 (#107)
11 persson 1808 - fixes for building with newer MinGW versions
12     - fix for building with bison 2.4 (#111)
13 persson 1842 - fixed building with libgig installed in a non-standard directory
14 persson 1895 - minor fix in configure for mmsystem.h detection on MinGW
15 persson 1897 - Windows: look for editor plugins and Fantasia using base
16 schoenebeck 1928 directory of liblinuxsampler dll (look in the same directory and one
17     directory above)
18 persson 1899 - configure script fix: removed unconditional use of SSE
19 persson 1923 - fixed building with sqlite installed in a non-standard directory
20 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
47 schoenebeck 1800 - maximum voices and disk streams can now be altered at runtime
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 schoenebeck 1601
62 schoenebeck 1599 * audio driver:
63     - removed the nonsense audio channel constraint (which was hard coded to
64     max. 100 audio channels) for most audio drivers
65 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
66     opposed to the LSCP specs
67 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
68     reflected the wrong value
69 persson 1644 - fixed a memory management bug in ASIO driver
70 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used
71 persson 1777 - JACK: use jack_client_open instead of the deprecated
72 persson 1748 jack_client_new
73 iliev 1829 - added (experimental) CoreAudio driver
74 persson 1888 - applied old fixes to the ASIO driver that were included in the
75     previous binary release but accidentally never committed to CVS
76     (fixes #117)
77 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
78     win64)
79 persson 1895 - VST: added support for sample rate and buffer size changes
80     - VST: close editor (Fantasia) when the VST is removed
81 persson 1908 - VST: avoid opening Fantasia more than once for each VST instance
82     - VST: export main function as "main" on Linux too (fix for
83     energyXT)
84 persson 1917 - VST: changed number of output channels from one stereo to 16
85     stereo
86 persson 1922 - added channel routing, fxsends and midi maps to the settings
87     stored in the plugin state
88 schoenebeck 1930 - performance optimization of AudioChannel::MixTo() and
89     AudioChannel::CopyTo() methods using GCC vector exensions
90     (if available)
91 schoenebeck 1599
92 persson 1651 * MIDI driver:
93     - added JACK MIDI driver
94 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
95     want to (mis)use it for some purpose ("fixed" in all current MIDI
96     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
97 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
98 persson 1887 CoreMidi or AU
99 persson 1889 - fixed mingw-w64 compilation error in MME driver
100 persson 1924 - made program change handling in MIDI thread real-time safe by
101     moving the logic to a non-RT thread
102 persson 1651
103 schoenebeck 1604 * instruments database:
104 iliev 1603 - avoid time consuming samples scanning when adding instruments
105     to the instruments database
106 iliev 1727 - added support for handling lost files in the instruments database
107 iliev 1781 - Implemented option for adding instruments in separate directories
108     in the instruments database
109     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
110 persson 1908 - work-around for missing fnmatch function on Windows to make
111     instrument database compilable
112 schoenebeck 1930 - added instrument database support on Windows
113     works with both standalone mode and VST plugin.
114     the instruments DB file is located in
115     %USERPROFILE%\.linuxsampler\instruments.db which allows different
116     databases for each windows user
117     if no DB is present it automatically creates the .linuxsampler subdir
118     and then creates an empty DB
119 iliev 1603
120 persson 1644 * Gigasampler format engine:
121     - fixed a memory leak that could happen when a channel was deleted
122     while notes were playing
123 persson 1646 - made it possible to load an instrument even if the audio thread
124     isn't running
125 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
126     enough for piano gigs with pedal noise samples
127 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
128     respective FX send MIDI controller was used
129 schoenebeck 1724 - added support for GM global device volume SysEx message
130 schoenebeck 1762 (can be selected at compile time to either apply globally to the
131     whole sampler [default] or only to the sampler channels that are
132     connected to the respective MIDI input port the SysEx message arrived
133     on)
134 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
135     sometimes wrongly killed in the same buffer, causing no sound to
136     be played
137 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
138     which is usally used to switch a part between chromatic sounds and
139     drumkit sounds (as opposed to their common default setting of MIDI
140     part 10 being a drumkit part and all other ones chromatic parts), in
141     LS however one can switch between the first 16 MIDI instrument maps
142     defined for the sampler
143 persson 1764 - made it possible to create multiple sample channels even if the
144     audio thread isn't running
145 persson 1844 - fixed crash when removing channel with active voices (#116)
146 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
147     un-cache the respective sample if it's really not used by any
148     sampler engine anymore
149     - re-cache samples in case they were changed by an instrument editor,
150     e.g. when a sample was added while playing (#82)
151 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
152     same time stamp as the voice's note-on event and occured both in the
153     same audio fragment cycle (fixes bug #112)
154 persson 1858 - added support for the "fine tune" and "pitch bend range"
155     instrument-level gig parameters
156     - fixed minor artifacts in pitch bend handling
157 schoenebeck 1860 - added support for GS Reset SysEx message
158 persson 1862 - allow gig files to use unlimited downward pitch shifting
159     - added a limit check for upward pitch shifting
160 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
161     note was silent
162 persson 1923 - fixed crash happening when a pitch bend event arrived at the
163     same time a new instrument was loading
164 persson 1644
165 schoenebeck 1687 * LSCP server:
166     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
167     react on MIDI data arriving on certain sampler channels (so far only
168     Note-On and Note-Off events are sent via this LSCP event)
169 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
170     react on MIDI data arriving on certain MIDI input devices (so far only
171     Note-On and Note-Off events are sent via this LSCP event)
172 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
173     SET DB_INSTRUMENT FILE_PATH
174 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
175     frontends to send MIDI messages to specific sampler channel
176     - added two additional fields to GET FILE INSTRUMENT INFO command -
177     KEY_BINDINGS and KEYSWITCH_BINDINGS
178 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
179     was incorrect
180 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
181 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
182     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
183     be triggered respectively
184     - added new LSCP command "SET STREAMS" to globally alter the maximum
185     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
186     which will be triggered respectively
187 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
188     a gigedit file dialog is opened)
189 iliev 1848 - close all connections when LSCPServer is deleted
190 iliev 1882 - hard close of all sockets on exit
191 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
192     driver
193 schoenebeck 1687
194 iliev 1761 * Bug fixes:
195     - fixed a crash which occurs when removing a sampler channel waiting
196     to start instrument loading after another channel
197 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
198     instrument loading in progress (bug #113)
199 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
200     instrument with PERSISTENT load mode
201 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
202     - fixed memory leaks when issuing the following LSCP commands:
203     GET AUDIO_OUTPUT_DRIVER INFO
204     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
205     GET MIDI_INPUT_DRIVER INFO
206     GET MIDI_INPUT_DRIVER_PARAMETER INFO
207     - fixed possible compilation error when sqlite is not present
208 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
209 iliev 1847 - fixed crash when changing the audio output device of a sampler
210     channel with loaded instrument and start playing notes
211 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
212 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
213     PowerPC, which probably could cause crashes on that platform
214 persson 1889 - fixed a memory management error which could cause a crash when a
215     plugin was unloaded
216 persson 1896 - bugfix: two private structs had the same name, which could cause
217     problems if the linker chose the wrong constructor
218 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
219     Windows
220 iliev 1761
221    
222 schoenebeck 1560 Version 0.5.1 (6 December 2007)
223 schoenebeck 1454
224     * packaging changes:
225     - added autoconf checks for pthread library
226     - added autoconf check for pthread bug found on certain NPTL-enabled
227     glibc versions (see Gentoo bug report #194076)
228 senoner 1502 - added autoconf checks for MS Windows
229 schoenebeck 1454
230 persson 1455 * general changes:
231     - bugfix: the thread used by an editor plugin didn't die when the
232     editor closed
233 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
234     out all the space. operator--() did not apply size_mask after
235     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
236     order to avoid problems with the _NonVolatileReader functions.
237     - bugfix: Stream.h: added a missing divide by BytesPerSample in
238     GetWriteSpace(). Since this function is currently only used in
239     the stream's qsort() compare function, it didn't trigger any
240     bugs.
241     - Resampler.h, Synthesizer.h: cubic interpolation now works in
242     24bit mode too. Faster method to read 24bit words on little
243     endian machines (x86): replaced 3 byte reads + shifts with a 1
244     unaligned 32bit read and shift
245     - experimental support for MS Windows (MIDI input via MME, AUDIO
246     output via ASIO)
247     - made handling of SIGINT signal (Ctrl-C) a bit more robust
248 iliev 1541 - support for monitoring the total number of active disk streams
249     (new LSCP commands: GET TOTAL_STREAM_COUNT,
250     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
251 persson 1455
252 senoner 1500 * AUDIO driver:
253 persson 1534 - added Windows ASIO low latency audio driver
254 senoner 1500
255 senoner 1485 * MIDI driver:
256 schoenebeck 1495 - added MME Windows MIDI driver
257 senoner 1485
258 schoenebeck 1471 * LSCP server:
259     - added support for Windows style path / filenames, however with
260     forward slash path separators instead of backslash
261     (i.e. "C:/foo/bar.gig")
262 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
263     apostrophes as well
264 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
265     "LIST FILE INSTRUMENTS <file>" and
266     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
267     about an arbitrary instrument file on the system where the sampler is
268     running on
269 schoenebeck 1471
270 schoenebeck 1424 Version 0.5.0 (15 October 2007)
271 schoenebeck 947
272 schoenebeck 1065 * packaging changes:
273 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
274     API header files anymore
275 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
276     the Doxygen API documentation (explicitly listed in Doxyfile.in)
277 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
278     capable to execute our autoconf environment, thus no need anymore
279     to maintain the compile time configuration file (osx/version.h) for
280     OSX manually (patch by Toshi Nagata)
281 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
282     parameters
283 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
284     C++ API header files, all implementation internal global definitions
285     are now in global_private.h
286     - atomic.h is not exposed to the C++ API anymore
287     - no need to include config.h anymore for using LS's API header files
288     - fixed warnings in API doc generation
289 schoenebeck 1065
290 schoenebeck 947 * general changes:
291     - replaced the old, confusing MIDI program change mechanism by a
292     flexible MIDI instrument mapper which allows to map arbitrary
293 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
294 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
295     loaded on the respective channel when such MIDI program change
296     messages arrive, beside that, each entry allows to define a life-time
297     strategy for the instrument, so the user can define whether the
298     instrument should i.e. be permanently loaded (to be able to switch
299     quickly among sounds) or i.e. loaded just on demand when the
300     respective program change arrives (to safe RAM space), as well as a
301     global volume factor for each entry, so the user can adjust the volume
302     dynamic of his mapped instrument collection without having to modify
303 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
304     MIDI instrument maps and assign each sampler channel individually
305     a certain map, so that i.e. separation of normal instruments and
306     drumkits is possible
307 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
308     MIDI instrument maps, MIDI instruments, FX sends, global volume.
309 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
310     due to a constant size RingBuffer FIFO which is now replaced by a
311     dynamic (unlimited) size std::list FIFO
312 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
313     output channels for being processed by external effect processors
314     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
315     controllers
316 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
317 iliev 1130 - Implemented new, improved notification system
318 schoenebeck 1149 - fixed compilation errors regarding OSX
319     (patch by Toshi Nagata)
320 iliev 1161 - implemented instruments database
321 iliev 1345 - added support for escape sequences to the instruments database
322 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
323     within the sampler's process (by using instrument editor plugins),
324     you'll notice the new "Registered instrument editors:" message on
325 schoenebeck 1407 startup, added a new LSCP command:
326     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
327 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
328     given sampler channel, the plugin path can be overridden at compile
329     time with ./configure --enable-plugin-dir=/some/dir
330 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
331     in the sampler's process to safely edit instruments while playing
332     without a crash (hopefully) by either suspending single regions
333     wherever possible or if unavoidable whole engine(s)
334 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
335     policy and priority on thread level, set a minimum stack size for
336     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
337     threads simply inherited properties of starting thread instead of
338     setting their own policy and priority
339 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
340     main process did not wait for the stack trace process to finish
341     its output
342 persson 1248 - fixed some minor memory leaks
343 schoenebeck 1259 - reenabled assembly features support, at the moment only for
344     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
345 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
346     register, to avoid relocations in the text segment at runtime)
347 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
348 schoenebeck 947
349     * MIDI driver:
350     - dispatch bank select (MSB and LSB) messages
351    
352 schoenebeck 1049 * audio driver:
353     - the ALSA audio output driver parameters now reflect the correct
354     parameter value ranges for the respective selected sound card
355     (patch by Till Wimmer, a bit fixed and extended)
356    
357 persson 951 * Gigasampler format engine:
358     - if a filter is used and EG2 finishes before EG1, let the voice
359     die when EG2 has finished (this fixes a problem with clicks and
360     voice starvation for some gigs)
361 persson 1038 - playback is no longer disabled during instrument loading
362     - all notes playing on a channel that changes its instrument keep
363     playing with the old instrument until they get a note off
364     command
365 persson 1039 - EG fix: a release value of zero could cause noises or crash
366 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
367 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
368     above max sustain level, which means that there is a decay phase
369     even if sustain is 100%
370 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
371     noises or crashes
372 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
373 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
374     supplied to the configure script (fixes #46)
375 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
376     instead of a fix value
377 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
378     127 (solo mode) only kill voices if the respective mode really
379     changed
380 persson 951
381 schoenebeck 1244 * LSCP server:
382     - fixed compile time error for old Bison versions
383     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
384 schoenebeck 1245 - parser now supports extended ASCII character set
385     (up to ASCII code 255, i.e. includes now umlauts and accents)
386     - filename arguments in LSCP commands now allow to use escape
387     sequences, that is directly literal as one of: \', \", \\, \n, \r,
388     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
389     code value like \xf2) (fixes bug #24)
390 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
391     least one of their text-based parameters (i.e. name, description):
392     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
393     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
394     "SET DB_INSTRUMENT_DIRECTORY NAME",
395     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
396     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
397     "FIND DB_INSTRUMENT_DIRECTORIES"
398 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
399     occured, the unexpected character and the actually expected, possible
400     character(s), the latter only if less than 5 possibilities)
401 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
402     settings
403 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
404     of strings were treated as being one string containing commas
405     (fixes #57)
406 schoenebeck 1244
407 iliev 959 * Bug fixes:
408     - fixed crash occurring on certain LSCP scripts (Bug 39)
409 persson 1038 - another thread safety fix for lscp "load engine" and "set
410     channel audio output device"
411 iliev 1283 - fixed a crash which occurs when reassigning the same engine
412     on a sampler channel with connected MIDI device
413 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
414     device connected to a sampler channel to number less then or equal
415     to the index of the port to which the sampler channel is connected.
416 iliev 1296 - The previous bindings were not been disconnected when altering
417     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
418     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
419 iliev 1297 - The active stream/voice count statistic was incorrect.
420 iliev 1298 - notification events were not been sent for some sampler
421     channel changes
422 iliev 1305 - added default min and max values to restrict the number of allowed
423     audio output channels and MIDI input ports
424 iliev 1306 - the connection to the PCM interface is now closed when destroying
425     an audio output device
426 schoenebeck 1332 - files with slash in their path or filename could not be loaded
427 iliev 959
428 schoenebeck 1221 * test cases:
429     - updated and fixed (haven't been touched in a while)
430    
431 schoenebeck 937 Version 0.4.0 (24 November 2006)
432 persson 696
433 schoenebeck 697 * packaging changes:
434 capela 868 - changed deprecated copyright attribute to license; added ldconfig
435     to post-(un)install steps; added devel package for liblinuxsampler;
436     to linuxsampler.spec (RPM)
437 schoenebeck 697 - install necessary development header files for allowing 3rd party
438     applications to link against liblinuxsampler
439     - liblinuxsampler's API documentation can be generated with 'make docs'
440     (Doxygen required)
441 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
442     implementation (currently either an integer math solution or a
443     di-harmonic approximation), automatic detection can be overriden
444     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
445     configure script argument though (mandatory for cross-compilation)
446 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
447     provided some on his own (as CXXFLAGS)
448 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
449     messages
450 schoenebeck 852 - added compile time options to allow disabling the various audio and
451     MIDI drivers
452 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
453     (patch by Ebrahim Mayat)
454 schoenebeck 697
455 persson 696 * Gigasampler format engine:
456 schoenebeck 738 - extensive synthesis optimization
457     (reimplementation of EGs and LFO(s), removed synthesis parameter
458     prerendering and the synthesis parameter matrix in general, splitting
459     each audio fragment into subfragments now where each subfragment uses
460 persson 830 constant pitch and filter coefficients. The volume coefficient is
461     linearly interpolated inside a subfragment, unless
462     --disable-interpolate-volume is set.)
463 persson 696 - fine tuning of the EG modulation parameters
464 persson 729 - improved filter cutoff calculation by adding support for the
465     following gig parameters: Cutoff freq (used when no cutoff
466     controller is defined), Control invert, Minimum cutoff, Velocity
467 persson 791 curve and Velocity range. The keyboard tracking now scales
468     cutoff frequency instead of resonance.
469 persson 877 - added support for gig parameter Resonance.
470 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
471 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
472     which can be overridden with --enable-global-attenuation
473 persson 783 - EG fixes: made the length of "attack hold" stage more
474     accurate. Release stage can now start before attack stage
475 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
476     time now has a minimal value to prevent clicks.
477 persson 799 - fixed pitch changes larger than one octave
478 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
479     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
480     all modes can be altered via standard GM messages, that is CC5 for
481     altering portamento time, CC65 for enabling / disabling portamento
482     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
483 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
484     parameter) and crossfade
485 persson 831 - added support for the "attenuation controller threshold" gig
486     parameter
487 persson 832 - added smoothing of volume changes caused by control change
488     messages
489 persson 865 - sample loop parameters are now taken from the DimensionRegion
490     instead of the wave chunk
491     - fixed keyswitching for v3 gigs with a number of keyswitch splits
492     not equal to a power of two
493 persson 877 - reimplementation of the filter algorithm. The new filter is more
494     accurate and supports all gig filter types, including bandreject
495     and lowpass turbo.
496 persson 903 - real support for 24 bit samples - samples are not truncated to
497     16 bits anymore
498     - support for aftertouch (channel pressure, not polyphonic
499     aftertouch)
500 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
501     amplifying from 0)
502 persson 696
503 schoenebeck 711 * LSCP server:
504     - fixed application exit on broken pipe error (fixes bug #20)
505 iliev 793 - fixed the notification messages delay due to lack of
506     network activity (fixes bug #26)
507 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
508     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
509 schoenebeck 711
510 schoenebeck 838 * audio driver:
511     - added aRts audio output driver (by no means RT safe)
512    
513 schoenebeck 775 * MIDI driver:
514     - fixed legacy sysex code which caused dispatching of MIDI SysEx
515     messages several times instead of once
516 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
517     for events (i.e. for offline rendering based MIDI drivers)
518 persson 922 - added checks for bad MIDI data
519 schoenebeck 775
520 schoenebeck 900 * linuxsampler application:
521     - show available sampler engine types on startup
522    
523 schoenebeck 705 * general changes:
524     - support for muting sampler channels and solo mode of the same, two new
525     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
526     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
527     introduced for this, the behavior is the same like on a mixer console
528 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
529     --enable-process-muted-channels which can be used to enable the
530     processing of muted channels.
531 iliev 777 - support for sostenuto pedal
532 iliev 779 - support for monitoring the total number of active voices
533 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
534     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
535 persson 835 - fixed some memory management errors
536 persson 841 - fixed some concurrency problems that could lead to crashes when
537     LSCP commands were executed
538 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
539     sampler channel (fixes bug #36)
540 schoenebeck 705
541 schoenebeck 692 Version 0.3.3 (15 July 2005)
542 schoenebeck 686
543     * packaging changes:
544     - fixed compilation with gcc 4.0
545    
546 schoenebeck 687 * Gigasampler format engine:
547     - LFO preprocessing was performed even though the respective LFO was
548     disabled by the instrument patch (minor efficiency fix)
549 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
550     for volume ramp downs in the same fragment (needed for current voice
551     stealing implementation) then simply inform the user with a warning
552     about possible click sounds and reduce the volume ramp down
553     appropriately instead of cancelling the audio device connection
554 schoenebeck 687
555 schoenebeck 677 Version 0.3.2 (24 June 2005)
556 schoenebeck 609
557     * packaging changes:
558     - updated autotools build files to compile on OS X
559     (conditional compilation of CoreMIDI and MidiShare drivers)
560 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
561     './configure --disable-asm' (definitely not recommended)
562 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
563     - require automake (>= 1.5) for 'make -f Makefile.cvs'
564     (due to 'dist-bzip2' automake option)
565 schoenebeck 649
566     * Gigasampler format engine:
567     - support for the gig parameters for "release velocity response" curves
568     - fine tuning of the EGADSR envelope
569     - volume of release triggered samples now depends on note-on velocity,
570     note length and gig parameter "release trigger decay" instead of
571     note-off velocity.
572 schoenebeck 663 - revised voice stealing
573     (fixes crash and endless loop caused by voice stealing)
574 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
575 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
576     instead of when the respective voice is actually launched
577     (fixes undefined behavior if stolen voices belonged to a key group -
578     this case was followed by a "killed voice survived" error message)
579 schoenebeck 669 - fixed minor issue with null/silence samples
580     (those stole voices even though they don't need a voice at all which
581     resulted in "voice stealing didn't work out" messages)
582 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
583     instrument or audio output device change
584 schoenebeck 654
585 schoenebeck 620 * LSCP server:
586 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
587 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
588 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
589 schoenebeck 609
590 schoenebeck 668 * linuxsampler application:
591     - added command line parameters --lscp-addr and --lscp-port to override
592     default IP address and port of LSCP server
593    
594 schoenebeck 579 Version 0.3.1 (24 May 2005)
595    
596     * initial release
