Sat Jul 4 12:31:44 2009 UTC (10 years, 5 months ago) by schoenebeck
File size: 30553 byte(s)
* fixed vector optimization code in AudioChannel.cpp:
  - application crashed when audio buffer(s) were not 16 byte aligned
    (e.g. the case with some VST host applications)
  - vector extension code was always to tried be compiled, even though the
    compiler didn't support vector extensions

1 schoenebeck 1599 Version CVS HEAD (?)
2    
3 schoenebeck 1639 * packaging changes:
4     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
5     causing e.g. the libgig test to fail when
6     "./configure --disable-jack-driver" was used
7     (patch by Alexis Ballier)
8 persson 1713 - fixed compilation with gcc 4.3
9 persson 1792 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
10 persson 1794 - fixed configure so it detects x86_64 (#107)
11 persson 1808 - fixes for building with newer MinGW versions
12     - fix for building with bison 2.4 (#111)
13 persson 1842 - fixed building with libgig installed in a non-standard directory
14 persson 1895 - minor fix in configure for mmsystem.h detection on MinGW
15 persson 1897 - Windows: look for editor plugins and Fantasia using base
16 schoenebeck 1928 directory of liblinuxsampler dll (look in the same directory and one
17     directory above)
18 persson 1899 - configure script fix: removed unconditional use of SSE
19 persson 1923 - fixed building with sqlite installed in a non-standard directory
20 schoenebeck 1639
21 schoenebeck 1601 * general changes:
22     - bugfix: on some POSIX systems instrument editor plugins refused to
23     load as we used a non-portable Linux specific struct field
24     (fixes bug #70, patch by Ronald Baljeu)
25 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
26     plugin DLL on Windows systems failed
27 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded
28     - optimized the SynchronizedConfig class so it doesn't wait
29     unnecessarily long after an update
30 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
31     events (e.g. to highlight the pressed keys on the virtual keyboard
32     of gigedit)
33 schoenebeck 1659 - added support for triggering notes by instrument editors (see above)
34 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
35 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation
36     is only used by very few systems, most pick the int math
37     implementation, which is usually faster)
38 persson 1748 - fixes for audio drivers with varying buffer sizes
39 persson 1777 - experimental support for running LinuxSampler as a DSSI, LV2 and
40     VST plugin
41 iliev 1789 - notification events for stream/voice count statistics are now sent
42     only when there are actual changes
43 persson 1790 - added memory ordering constraints to improve stability on
44     multi-core and multi-cpu systems
45 schoenebeck 1800 - maximum voices and disk streams can now be altered at runtime
46 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
47 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
48     be switched on by command line option "--stacktrace" (the automatic
49     stacktrace mechanism seems to be broken on most systems at the moment)
50 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
51     a pointer to the launched InstrumentEditor object
52 schoenebeck 1876 - added optional 3rd party user data parameter for following
53     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
54     InstrumentEditor::Launch(),
55     InstrumentManager::LaunchInstrumentEditor()
56 persson 1887 - theoretical fix: made SynchronizedConfig follow C++0x memory
57     model more strictly
58 persson 1895 - fixes for using large audio device buffers
59 schoenebeck 1601
60 schoenebeck 1599 * audio driver:
61     - removed the nonsense audio channel constraint (which was hard coded to
62     max. 100 audio channels) for most audio drivers
63 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
64     opposed to the LSCP specs
65 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
66     reflected the wrong value
67 persson 1644 - fixed a memory management bug in ASIO driver
68 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used
69 persson 1777 - JACK: use jack_client_open instead of the deprecated
70 persson 1748 jack_client_new
71 iliev 1829 - added (experimental) CoreAudio driver
72 persson 1888 - applied old fixes to the ASIO driver that were included in the
73     previous binary release but accidentally never committed to CVS
74     (fixes #117)
75 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
76     win64)
77 persson 1895 - VST: added support for sample rate and buffer size changes
78     - VST: close editor (Fantasia) when the VST is removed
79 persson 1908 - VST: avoid opening Fantasia more than once for each VST instance
80     - VST: export main function as "main" on Linux too (fix for
81     energyXT)
82 persson 1917 - VST: changed number of output channels from one stereo to 16
83     stereo
84 persson 1922 - added channel routing, fxsends and midi maps to the settings
85     stored in the plugin state
86 schoenebeck 1930 - performance optimization of AudioChannel::MixTo() and
87     AudioChannel::CopyTo() methods using GCC vector exensions
88     (if available)
89 schoenebeck 1599
90 persson 1651 * MIDI driver:
91     - added JACK MIDI driver
92 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
93     want to (mis)use it for some purpose ("fixed" in all current MIDI
94     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
95 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
96 persson 1887 CoreMidi or AU
97 persson 1889 - fixed mingw-w64 compilation error in MME driver
98 persson 1924 - made program change handling in MIDI thread real-time safe by
99     moving the logic to a non-RT thread
100 persson 1651
101 schoenebeck 1604 * instruments database:
102 iliev 1603 - avoid time consuming samples scanning when adding instruments
103     to the instruments database
104 iliev 1727 - added support for handling lost files in the instruments database
105 iliev 1781 - Implemented option for adding instruments in separate directories
106     in the instruments database
107     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
108 persson 1908 - work-around for missing fnmatch function on Windows to make
109     instrument database compilable
110 schoenebeck 1930 - added instrument database support on Windows
111     works with both standalone mode and VST plugin.
112     the instruments DB file is located in
113     %USERPROFILE%\.linuxsampler\instruments.db which allows different
114     databases for each windows user
115     if no DB is present it automatically creates the .linuxsampler subdir
116     and then creates an empty DB
117 iliev 1603
118 persson 1644 * Gigasampler format engine:
119     - fixed a memory leak that could happen when a channel was deleted
120     while notes were playing
121 persson 1646 - made it possible to load an instrument even if the audio thread
122     isn't running
123 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
124     enough for piano gigs with pedal noise samples
125 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
126     respective FX send MIDI controller was used
127 schoenebeck 1724 - added support for GM global device volume SysEx message
128 schoenebeck 1762 (can be selected at compile time to either apply globally to the
129     whole sampler [default] or only to the sampler channels that are
130     connected to the respective MIDI input port the SysEx message arrived
131     on)
132 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
133     sometimes wrongly killed in the same buffer, causing no sound to
134     be played
135 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
136     which is usally used to switch a part between chromatic sounds and
137     drumkit sounds (as opposed to their common default setting of MIDI
138     part 10 being a drumkit part and all other ones chromatic parts), in
139     LS however one can switch between the first 16 MIDI instrument maps
140     defined for the sampler
141 persson 1764 - made it possible to create multiple sample channels even if the
142     audio thread isn't running
143 persson 1844 - fixed crash when removing channel with active voices (#116)
144 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
145     un-cache the respective sample if it's really not used by any
146     sampler engine anymore
147     - re-cache samples in case they were changed by an instrument editor,
148     e.g. when a sample was added while playing (#82)
149 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
150     same time stamp as the voice's note-on event and occured both in the
151     same audio fragment cycle (fixes bug #112)
152 persson 1858 - added support for the "fine tune" and "pitch bend range"
153     instrument-level gig parameters
154     - fixed minor artifacts in pitch bend handling
155 schoenebeck 1860 - added support for GS Reset SysEx message
156 persson 1862 - allow gig files to use unlimited downward pitch shifting
157     - added a limit check for upward pitch shifting
158 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
159     note was silent
160 persson 1923 - fixed crash happening when a pitch bend event arrived at the
161     same time a new instrument was loading
162 persson 1644
163 schoenebeck 1687 * LSCP server:
164     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
165     react on MIDI data arriving on certain sampler channels (so far only
166     Note-On and Note-Off events are sent via this LSCP event)
167 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
168     react on MIDI data arriving on certain MIDI input devices (so far only
169     Note-On and Note-Off events are sent via this LSCP event)
170 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
171     SET DB_INSTRUMENT FILE_PATH
172 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
173     frontends to send MIDI messages to specific sampler channel
174     - added two additional fields to GET FILE INSTRUMENT INFO command -
175     KEY_BINDINGS and KEYSWITCH_BINDINGS
176 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
177     was incorrect
178 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
179 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
180     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
181     be triggered respectively
182     - added new LSCP command "SET STREAMS" to globally alter the maximum
183     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
184     which will be triggered respectively
185 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
186     a gigedit file dialog is opened)
187 iliev 1848 - close all connections when LSCPServer is deleted
188 iliev 1882 - hard close of all sockets on exit
189 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
190     driver
191 schoenebeck 1687
192 iliev 1761 * Bug fixes:
193     - fixed a crash which occurs when removing a sampler channel waiting
194     to start instrument loading after another channel
195 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
196     instrument loading in progress (bug #113)
197 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
198     instrument with PERSISTENT load mode
199 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
200     - fixed memory leaks when issuing the following LSCP commands:
201     GET AUDIO_OUTPUT_DRIVER INFO
202     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
203     GET MIDI_INPUT_DRIVER INFO
204     GET MIDI_INPUT_DRIVER_PARAMETER INFO
205     - fixed possible compilation error when sqlite is not present
206 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
207 iliev 1847 - fixed crash when changing the audio output device of a sampler
208     channel with loaded instrument and start playing notes
209 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
210 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
211     PowerPC, which probably could cause crashes on that platform
212 persson 1889 - fixed a memory management error which could cause a crash when a
213     plugin was unloaded
214 persson 1896 - bugfix: two private structs had the same name, which could cause
215     problems if the linker chose the wrong constructor
216 iliev 1761
217    
218 schoenebeck 1560 Version 0.5.1 (6 December 2007)
219 schoenebeck 1454
220     * packaging changes:
221     - added autoconf checks for pthread library
222     - added autoconf check for pthread bug found on certain NPTL-enabled
223     glibc versions (see Gentoo bug report #194076)
224 senoner 1502 - added autoconf checks for MS Windows
225 schoenebeck 1454
226 persson 1455 * general changes:
227     - bugfix: the thread used by an editor plugin didn't die when the
228     editor closed
229 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
230     out all the space. operator--() did not apply size_mask after
231     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
232     order to avoid problems with the _NonVolatileReader functions.
233     - bugfix: Stream.h: added a missing divide by BytesPerSample in
234     GetWriteSpace(). Since this function is currently only used in
235     the stream's qsort() compare function, it didn't trigger any
236     bugs.
237     - Resampler.h, Synthesizer.h: cubic interpolation now works in
238     24bit mode too. Faster method to read 24bit words on little
239     endian machines (x86): replaced 3 byte reads + shifts with a 1
240     unaligned 32bit read and shift
241     - experimental support for MS Windows (MIDI input via MME, AUDIO
242     output via ASIO)
243     - made handling of SIGINT signal (Ctrl-C) a bit more robust
244 iliev 1541 - support for monitoring the total number of active disk streams
245     (new LSCP commands: GET TOTAL_STREAM_COUNT,
246     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
247 persson 1455
248 senoner 1500 * AUDIO driver:
249 persson 1534 - added Windows ASIO low latency audio driver
250 senoner 1500
251 senoner 1485 * MIDI driver:
252 schoenebeck 1495 - added MME Windows MIDI driver
253 senoner 1485
254 schoenebeck 1471 * LSCP server:
255     - added support for Windows style path / filenames, however with
256     forward slash path separators instead of backslash
257     (i.e. "C:/foo/bar.gig")
258 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
259     apostrophes as well
260 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
261     "LIST FILE INSTRUMENTS <file>" and
262     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
263     about an arbitrary instrument file on the system where the sampler is
264     running on
265 schoenebeck 1471
266 schoenebeck 1424 Version 0.5.0 (15 October 2007)
267 schoenebeck 947
268 schoenebeck 1065 * packaging changes:
269 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
270     API header files anymore
271 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
272     the Doxygen API documentation (explicitly listed in Doxyfile.in)
273 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
274     capable to execute our autoconf environment, thus no need anymore
275     to maintain the compile time configuration file (osx/version.h) for
276     OSX manually (patch by Toshi Nagata)
277 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
278     parameters
279 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
280     C++ API header files, all implementation internal global definitions
281     are now in global_private.h
282     - atomic.h is not exposed to the C++ API anymore
283     - no need to include config.h anymore for using LS's API header files
284     - fixed warnings in API doc generation
285 schoenebeck 1065
286 schoenebeck 947 * general changes:
287     - replaced the old, confusing MIDI program change mechanism by a
288     flexible MIDI instrument mapper which allows to map arbitrary
289 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
290 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
291     loaded on the respective channel when such MIDI program change
292     messages arrive, beside that, each entry allows to define a life-time
293     strategy for the instrument, so the user can define whether the
294     instrument should i.e. be permanently loaded (to be able to switch
295     quickly among sounds) or i.e. loaded just on demand when the
296     respective program change arrives (to safe RAM space), as well as a
297     global volume factor for each entry, so the user can adjust the volume
298     dynamic of his mapped instrument collection without having to modify
299 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
300     MIDI instrument maps and assign each sampler channel individually
301     a certain map, so that i.e. separation of normal instruments and
302     drumkits is possible
303 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
304     MIDI instrument maps, MIDI instruments, FX sends, global volume.
305 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
306     due to a constant size RingBuffer FIFO which is now replaced by a
307     dynamic (unlimited) size std::list FIFO
308 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
309     output channels for being processed by external effect processors
310     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
311     controllers
312 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
313 iliev 1130 - Implemented new, improved notification system
314 schoenebeck 1149 - fixed compilation errors regarding OSX
315     (patch by Toshi Nagata)
316 iliev 1161 - implemented instruments database
317 iliev 1345 - added support for escape sequences to the instruments database
318 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
319     within the sampler's process (by using instrument editor plugins),
320     you'll notice the new "Registered instrument editors:" message on
321 schoenebeck 1407 startup, added a new LSCP command:
322     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
323 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
324     given sampler channel, the plugin path can be overridden at compile
325     time with ./configure --enable-plugin-dir=/some/dir
326 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
327     in the sampler's process to safely edit instruments while playing
328     without a crash (hopefully) by either suspending single regions
329     wherever possible or if unavoidable whole engine(s)
330 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
331     policy and priority on thread level, set a minimum stack size for
332     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
333     threads simply inherited properties of starting thread instead of
334     setting their own policy and priority
335 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
336     main process did not wait for the stack trace process to finish
337     its output
338 persson 1248 - fixed some minor memory leaks
339 schoenebeck 1259 - reenabled assembly features support, at the moment only for
340     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
341 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
342     register, to avoid relocations in the text segment at runtime)
343 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
344 schoenebeck 947
345     * MIDI driver:
346     - dispatch bank select (MSB and LSB) messages
347    
348 schoenebeck 1049 * audio driver:
349     - the ALSA audio output driver parameters now reflect the correct
350     parameter value ranges for the respective selected sound card
351     (patch by Till Wimmer, a bit fixed and extended)
352    
353 persson 951 * Gigasampler format engine:
354     - if a filter is used and EG2 finishes before EG1, let the voice
355     die when EG2 has finished (this fixes a problem with clicks and
356     voice starvation for some gigs)
357 persson 1038 - playback is no longer disabled during instrument loading
358     - all notes playing on a channel that changes its instrument keep
359     playing with the old instrument until they get a note off
360     command
361 persson 1039 - EG fix: a release value of zero could cause noises or crash
362 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
363 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
364     above max sustain level, which means that there is a decay phase
365     even if sustain is 100%
366 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
367     noises or crashes
368 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
369 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
370     supplied to the configure script (fixes #46)
371 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
372     instead of a fix value
373 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
374     127 (solo mode) only kill voices if the respective mode really
375     changed
376 persson 951
377 schoenebeck 1244 * LSCP server:
378     - fixed compile time error for old Bison versions
379     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
380 schoenebeck 1245 - parser now supports extended ASCII character set
381     (up to ASCII code 255, i.e. includes now umlauts and accents)
382     - filename arguments in LSCP commands now allow to use escape
383     sequences, that is directly literal as one of: \', \", \\, \n, \r,
384     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
385     code value like \xf2) (fixes bug #24)
386 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
387     least one of their text-based parameters (i.e. name, description):
388     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
389     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
390     "SET DB_INSTRUMENT_DIRECTORY NAME",
391     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
392     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
393     "FIND DB_INSTRUMENT_DIRECTORIES"
394 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
395     occured, the unexpected character and the actually expected, possible
396     character(s), the latter only if less than 5 possibilities)
397 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
398     settings
399 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
400     of strings were treated as being one string containing commas
401     (fixes #57)
402 schoenebeck 1244
403 iliev 959 * Bug fixes:
404     - fixed crash occurring on certain LSCP scripts (Bug 39)
405 persson 1038 - another thread safety fix for lscp "load engine" and "set
406     channel audio output device"
407 iliev 1283 - fixed a crash which occurs when reassigning the same engine
408     on a sampler channel with connected MIDI device
409 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
410     device connected to a sampler channel to number less then or equal
411     to the index of the port to which the sampler channel is connected.
412 iliev 1296 - The previous bindings were not been disconnected when altering
413     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
414     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
415 iliev 1297 - The active stream/voice count statistic was incorrect.
416 iliev 1298 - notification events were not been sent for some sampler
417     channel changes
418 iliev 1305 - added default min and max values to restrict the number of allowed
419     audio output channels and MIDI input ports
420 iliev 1306 - the connection to the PCM interface is now closed when destroying
421     an audio output device
422 schoenebeck 1332 - files with slash in their path or filename could not be loaded
423 iliev 959
424 schoenebeck 1221 * test cases:
425     - updated and fixed (haven't been touched in a while)
426    
427 schoenebeck 937 Version 0.4.0 (24 November 2006)
428 persson 696
429 schoenebeck 697 * packaging changes:
430 capela 868 - changed deprecated copyright attribute to license; added ldconfig
431     to post-(un)install steps; added devel package for liblinuxsampler;
432     to linuxsampler.spec (RPM)
433 schoenebeck 697 - install necessary development header files for allowing 3rd party
434     applications to link against liblinuxsampler
435     - liblinuxsampler's API documentation can be generated with 'make docs'
436     (Doxygen required)
437 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
438     implementation (currently either an integer math solution or a
439     di-harmonic approximation), automatic detection can be overriden
440     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
441     configure script argument though (mandatory for cross-compilation)
442 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
443     provided some on his own (as CXXFLAGS)
444 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
445     messages
446 schoenebeck 852 - added compile time options to allow disabling the various audio and
447     MIDI drivers
448 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
449     (patch by Ebrahim Mayat)
450 schoenebeck 697
451 persson 696 * Gigasampler format engine:
452 schoenebeck 738 - extensive synthesis optimization
453     (reimplementation of EGs and LFO(s), removed synthesis parameter
454     prerendering and the synthesis parameter matrix in general, splitting
455     each audio fragment into subfragments now where each subfragment uses
456 persson 830 constant pitch and filter coefficients. The volume coefficient is
457     linearly interpolated inside a subfragment, unless
458     --disable-interpolate-volume is set.)
459 persson 696 - fine tuning of the EG modulation parameters
460 persson 729 - improved filter cutoff calculation by adding support for the
461     following gig parameters: Cutoff freq (used when no cutoff
462     controller is defined), Control invert, Minimum cutoff, Velocity
463 persson 791 curve and Velocity range. The keyboard tracking now scales
464     cutoff frequency instead of resonance.
465 persson 877 - added support for gig parameter Resonance.
466 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
467 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
468     which can be overridden with --enable-global-attenuation
469 persson 783 - EG fixes: made the length of "attack hold" stage more
470     accurate. Release stage can now start before attack stage
471 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
472     time now has a minimal value to prevent clicks.
473 persson 799 - fixed pitch changes larger than one octave
474 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
475     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
476     all modes can be altered via standard GM messages, that is CC5 for
477     altering portamento time, CC65 for enabling / disabling portamento
478     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
479 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
480     parameter) and crossfade
481 persson 831 - added support for the "attenuation controller threshold" gig
482     parameter
483 persson 832 - added smoothing of volume changes caused by control change
484     messages
485 persson 865 - sample loop parameters are now taken from the DimensionRegion
486     instead of the wave chunk
487     - fixed keyswitching for v3 gigs with a number of keyswitch splits
488     not equal to a power of two
489 persson 877 - reimplementation of the filter algorithm. The new filter is more
490     accurate and supports all gig filter types, including bandreject
491     and lowpass turbo.
492 persson 903 - real support for 24 bit samples - samples are not truncated to
493     16 bits anymore
494     - support for aftertouch (channel pressure, not polyphonic
495     aftertouch)
496 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
497     amplifying from 0)
498 persson 696
499 schoenebeck 711 * LSCP server:
500     - fixed application exit on broken pipe error (fixes bug #20)
501 iliev 793 - fixed the notification messages delay due to lack of
502     network activity (fixes bug #26)
503 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
504     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
505 schoenebeck 711
506 schoenebeck 838 * audio driver:
507     - added aRts audio output driver (by no means RT safe)
508    
509 schoenebeck 775 * MIDI driver:
510     - fixed legacy sysex code which caused dispatching of MIDI SysEx
511     messages several times instead of once
512 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
513     for events (i.e. for offline rendering based MIDI drivers)
514 persson 922 - added checks for bad MIDI data
515 schoenebeck 775
516 schoenebeck 900 * linuxsampler application:
517     - show available sampler engine types on startup
518    
519 schoenebeck 705 * general changes:
520     - support for muting sampler channels and solo mode of the same, two new
521     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
522     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
523     introduced for this, the behavior is the same like on a mixer console
524 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
525     --enable-process-muted-channels which can be used to enable the
526     processing of muted channels.
527 iliev 777 - support for sostenuto pedal
528 iliev 779 - support for monitoring the total number of active voices
529 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
530     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
531 persson 835 - fixed some memory management errors
532 persson 841 - fixed some concurrency problems that could lead to crashes when
533     LSCP commands were executed
534 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
535     sampler channel (fixes bug #36)
536 schoenebeck 705
537 schoenebeck 692 Version 0.3.3 (15 July 2005)
538 schoenebeck 686
539     * packaging changes:
540     - fixed compilation with gcc 4.0
541    
542 schoenebeck 687 * Gigasampler format engine:
543     - LFO preprocessing was performed even though the respective LFO was
544     disabled by the instrument patch (minor efficiency fix)
545 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
546     for volume ramp downs in the same fragment (needed for current voice
547     stealing implementation) then simply inform the user with a warning
548     about possible click sounds and reduce the volume ramp down
549     appropriately instead of cancelling the audio device connection
550 schoenebeck 687
551 schoenebeck 677 Version 0.3.2 (24 June 2005)
552 schoenebeck 609
553     * packaging changes:
554     - updated autotools build files to compile on OS X
555     (conditional compilation of CoreMIDI and MidiShare drivers)
556 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
557     './configure --disable-asm' (definitely not recommended)
558 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
559     - require automake (>= 1.5) for 'make -f Makefile.cvs'
560     (due to 'dist-bzip2' automake option)
561 schoenebeck 649
562     * Gigasampler format engine:
563     - support for the gig parameters for "release velocity response" curves
564     - fine tuning of the EGADSR envelope
565     - volume of release triggered samples now depends on note-on velocity,
566     note length and gig parameter "release trigger decay" instead of
567     note-off velocity.
568 schoenebeck 663 - revised voice stealing
569     (fixes crash and endless loop caused by voice stealing)
570 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
571 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
572     instead of when the respective voice is actually launched
573     (fixes undefined behavior if stolen voices belonged to a key group -
574     this case was followed by a "killed voice survived" error message)
575 schoenebeck 669 - fixed minor issue with null/silence samples
576     (those stole voices even though they don't need a voice at all which
577     resulted in "voice stealing didn't work out" messages)
578 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
579     instrument or audio output device change
580 schoenebeck 654
581 schoenebeck 620 * LSCP server:
582 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
583 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
584 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
585 schoenebeck 609
586 schoenebeck 668 * linuxsampler application:
587     - added command line parameters --lscp-addr and --lscp-port to override
588     default IP address and port of LSCP server
589    
590 schoenebeck 579 Version 0.3.1 (24 May 2005)
591    
592     * initial release
