* VST: changed number of output channels from one stereo to 16 stereo

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     directory of liblinuxsampler dll
17 persson 1899 - configure script fix: removed unconditional use of SSE
18 schoenebeck 1639
19 schoenebeck 1601 * general changes:
20     - bugfix: on some POSIX systems instrument editor plugins refused to
21     load as we used a non-portable Linux specific struct field
22     (fixes bug #70, patch by Ronald Baljeu)
23 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
24     plugin DLL on Windows systems failed
25 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded
26     - optimized the SynchronizedConfig class so it doesn't wait
27     unnecessarily long after an update
28 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
29     events (e.g. to highlight the pressed keys on the virtual keyboard
30     of gigedit)
31 schoenebeck 1659 - added support for triggering notes by instrument editors (see above)
32 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
33 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation
34     is only used by very few systems, most pick the int math
35     implementation, which is usually faster)
36 persson 1748 - fixes for audio drivers with varying buffer sizes
37 persson 1777 - experimental support for running LinuxSampler as a DSSI, LV2 and
38     VST plugin
39 iliev 1789 - notification events for stream/voice count statistics are now sent
40     only when there are actual changes
41 persson 1790 - added memory ordering constraints to improve stability on
42     multi-core and multi-cpu systems
43 schoenebeck 1800 - maximum voices and disk streams can now be altered at runtime
44 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
45 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
46     be switched on by command line option "--stacktrace" (the automatic
47     stacktrace mechanism seems to be broken on most systems at the moment)
48 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
49     a pointer to the launched InstrumentEditor object
50 schoenebeck 1876 - added optional 3rd party user data parameter for following
51     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
52     InstrumentEditor::Launch(),
53     InstrumentManager::LaunchInstrumentEditor()
54 persson 1887 - theoretical fix: made SynchronizedConfig follow C++0x memory
55     model more strictly
56 persson 1895 - fixes for using large audio device buffers
57 schoenebeck 1601
58 schoenebeck 1599 * audio driver:
59     - removed the nonsense audio channel constraint (which was hard coded to
60     max. 100 audio channels) for most audio drivers
61 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
62     opposed to the LSCP specs
63 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
64     reflected the wrong value
65 persson 1644 - fixed a memory management bug in ASIO driver
66 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used
67 persson 1777 - JACK: use jack_client_open instead of the deprecated
68 persson 1748 jack_client_new
69 iliev 1829 - added (experimental) CoreAudio driver
70 persson 1888 - applied old fixes to the ASIO driver that were included in the
71     previous binary release but accidentally never committed to CVS
72     (fixes #117)
73 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
74     win64)
75 persson 1895 - VST: added support for sample rate and buffer size changes
76     - VST: close editor (Fantasia) when the VST is removed
77 persson 1908 - VST: avoid opening Fantasia more than once for each VST instance
78     - VST: export main function as "main" on Linux too (fix for
79     energyXT)
80 persson 1917 - VST: changed number of output channels from one stereo to 16
81     stereo
82 schoenebeck 1599
83 persson 1651 * MIDI driver:
84     - added JACK MIDI driver
85 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
86     want to (mis)use it for some purpose ("fixed" in all current MIDI
87     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
88 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
89 persson 1887 CoreMidi or AU
90 persson 1889 - fixed mingw-w64 compilation error in MME driver
91 persson 1651
92 schoenebeck 1604 * instruments database:
93 iliev 1603 - avoid time consuming samples scanning when adding instruments
94     to the instruments database
95 iliev 1727 - added support for handling lost files in the instruments database

97     in the instruments database
98     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
99 persson 1908 - work-around for missing fnmatch function on Windows to make
100     instrument database compilable
101 senoner 1910 - added instrument database support on Windows
102 senoner 1911 works with both standalone mode and VST plugin.
103     the instruments DB file is located in
104     %USERPROFILE%\.linuxsampler\instruments.db which allows different
105     databases for each windows user
106 senoner 1912 if no DB is present it automatically creates the .linuxsampler subdir
107     and then creates an empty DB
108 iliev 1603
109 persson 1644 * Gigasampler format engine:
110     - fixed a memory leak that could happen when a channel was deleted
111     while notes were playing
112 persson 1646 - made it possible to load an instrument even if the audio thread
113     isn't running
114 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
115     enough for piano gigs with pedal noise samples
116 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
117     respective FX send MIDI controller was used
118 schoenebeck 1724 - added support for GM global device volume SysEx message
119 schoenebeck 1762 (can be selected at compile time to either apply globally to the
120     whole sampler [default] or only to the sampler channels that are
121     connected to the respective MIDI input port the SysEx message arrived
122     on)
123 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
124     sometimes wrongly killed in the same buffer, causing no sound to
125     be played
126 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
127     which is usally used to switch a part between chromatic sounds and
128     drumkit sounds (as opposed to their common default setting of MIDI
129     part 10 being a drumkit part and all other ones chromatic parts), in
130     LS however one can switch between the first 16 MIDI instrument maps
131     defined for the sampler
132 persson 1764 - made it possible to create multiple sample channels even if the
133     audio thread isn't running
134 persson 1844 - fixed crash when removing channel with active voices (#116)
135 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
136     un-cache the respective sample if it's really not used by any
137     sampler engine anymore
138     - re-cache samples in case they were changed by an instrument editor,
139     e.g. when a sample was added while playing (#82)
140 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
141     same time stamp as the voice's note-on event and occured both in the
142     same audio fragment cycle (fixes bug #112)
143 persson 1858 - added support for the "fine tune" and "pitch bend range"
144     instrument-level gig parameters
145     - fixed minor artifacts in pitch bend handling
146 schoenebeck 1860 - added support for GS Reset SysEx message
147 persson 1862 - allow gig files to use unlimited downward pitch shifting
148     - added a limit check for upward pitch shifting
149 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
150     note was silent
151 persson 1644
152 schoenebeck 1687 * LSCP server:
153     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
154     react on MIDI data arriving on certain sampler channels (so far only
155     Note-On and Note-Off events are sent via this LSCP event)
156 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
157     react on MIDI data arriving on certain MIDI input devices (so far only
158     Note-On and Note-Off events are sent via this LSCP event)
159 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
160     SET DB_INSTRUMENT FILE_PATH
161 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
162     frontends to send MIDI messages to specific sampler channel
163     - added two additional fields to GET FILE INSTRUMENT INFO command -
164     KEY_BINDINGS and KEYSWITCH_BINDINGS
165 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
166     was incorrect
167 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
168 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
169     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
170     be triggered respectively
171     - added new LSCP command "SET STREAMS" to globally alter the maximum
172     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
173     which will be triggered respectively
174 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
175     a gigedit file dialog is opened)
176 iliev 1848 - close all connections when LSCPServer is deleted
177 iliev 1882 - hard close of all sockets on exit
178 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
179     driver
180 schoenebeck 1687
181 iliev 1761 * Bug fixes:
182     - fixed a crash which occurs when removing a sampler channel waiting
183     to start instrument loading after another channel
184 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
185     instrument loading in progress (bug #113)
186 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
187     instrument with PERSISTENT load mode
188 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
189     - fixed memory leaks when issuing the following LSCP commands:
190     GET AUDIO_OUTPUT_DRIVER INFO
191     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
192     GET MIDI_INPUT_DRIVER INFO
193     GET MIDI_INPUT_DRIVER_PARAMETER INFO
194     - fixed possible compilation error when sqlite is not present
195 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
196 iliev 1847 - fixed crash when changing the audio output device of a sampler
197     channel with loaded instrument and start playing notes
198 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
199 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
200     PowerPC, which probably could cause crashes on that platform
201 persson 1889 - fixed a memory management error which could cause a crash when a
202     plugin was unloaded
203 persson 1896 - bugfix: two private structs had the same name, which could cause
204     problems if the linker chose the wrong constructor
205 iliev 1761
206    
207 schoenebeck 1560 Version 0.5.1 (6 December 2007)
208 schoenebeck 1454
209     * packaging changes:
210     - added autoconf checks for pthread library
211     - added autoconf check for pthread bug found on certain NPTL-enabled
212     glibc versions (see Gentoo bug report #194076)
213 senoner 1502 - added autoconf checks for MS Windows
214 schoenebeck 1454
215 persson 1455 * general changes:
216     - bugfix: the thread used by an editor plugin didn't die when the
217     editor closed
218 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
219     out all the space. operator--() did not apply size_mask after
220     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
221     order to avoid problems with the _NonVolatileReader functions.
222     - bugfix: Stream.h: added a missing divide by BytesPerSample in
223     GetWriteSpace(). Since this function is currently only used in
224     the stream's qsort() compare function, it didn't trigger any
225     bugs.
226     - Resampler.h, Synthesizer.h: cubic interpolation now works in
227     24bit mode too. Faster method to read 24bit words on little
228     endian machines (x86): replaced 3 byte reads + shifts with a 1
229     unaligned 32bit read and shift
230     - experimental support for MS Windows (MIDI input via MME, AUDIO
231     output via ASIO)
232     - made handling of SIGINT signal (Ctrl-C) a bit more robust
233 iliev 1541 - support for monitoring the total number of active disk streams
234     (new LSCP commands: GET TOTAL_STREAM_COUNT,
235     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
236 persson 1455
237 senoner 1500 * AUDIO driver:
238 persson 1534 - added Windows ASIO low latency audio driver
239 senoner 1500
240 senoner 1485 * MIDI driver:
241 schoenebeck 1495 - added MME Windows MIDI driver
242 senoner 1485
243 schoenebeck 1471 * LSCP server:
244     - added support for Windows style path / filenames, however with
245     forward slash path separators instead of backslash
246     (i.e. "C:/foo/bar.gig")
247 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
248     apostrophes as well
249 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
250     "LIST FILE INSTRUMENTS <file>" and
251     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
252     about an arbitrary instrument file on the system where the sampler is
253     running on
254 schoenebeck 1471
255 schoenebeck 1424 Version 0.5.0 (15 October 2007)
256 schoenebeck 947
257 schoenebeck 1065 * packaging changes:
258 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
259     API header files anymore
260 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
261     the Doxygen API documentation (explicitly listed in Doxyfile.in)
262 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
263     capable to execute our autoconf environment, thus no need anymore
264     to maintain the compile time configuration file (osx/version.h) for
265     OSX manually (patch by Toshi Nagata)
266 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
267     parameters
268 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
269     C++ API header files, all implementation internal global definitions
270     are now in global_private.h
271     - atomic.h is not exposed to the C++ API anymore
272     - no need to include config.h anymore for using LS's API header files
273     - fixed warnings in API doc generation
274 schoenebeck 1065
275 schoenebeck 947 * general changes:
276     - replaced the old, confusing MIDI program change mechanism by a
277     flexible MIDI instrument mapper which allows to map arbitrary
278 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
279 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
280     loaded on the respective channel when such MIDI program change
281     messages arrive, beside that, each entry allows to define a life-time
282     strategy for the instrument, so the user can define whether the
283     instrument should i.e. be permanently loaded (to be able to switch
284     quickly among sounds) or i.e. loaded just on demand when the
285     respective program change arrives (to safe RAM space), as well as a
286     global volume factor for each entry, so the user can adjust the volume
287     dynamic of his mapped instrument collection without having to modify
288 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
289     MIDI instrument maps and assign each sampler channel individually
290     a certain map, so that i.e. separation of normal instruments and
291     drumkits is possible
292 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
293     MIDI instrument maps, MIDI instruments, FX sends, global volume.
294 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
295     due to a constant size RingBuffer FIFO which is now replaced by a
296     dynamic (unlimited) size std::list FIFO
297 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
298     output channels for being processed by external effect processors
299     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
300     controllers
301 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
302 iliev 1130 - Implemented new, improved notification system
303 schoenebeck 1149 - fixed compilation errors regarding OSX
304     (patch by Toshi Nagata)
305 iliev 1161 - implemented instruments database
306 iliev 1345 - added support for escape sequences to the instruments database
307 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
308     within the sampler's process (by using instrument editor plugins),
309     you'll notice the new "Registered instrument editors:" message on
310 schoenebeck 1407 startup, added a new LSCP command:
311     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
312 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
313     given sampler channel, the plugin path can be overridden at compile
314     time with ./configure --enable-plugin-dir=/some/dir
315 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
316     in the sampler's process to safely edit instruments while playing
317     without a crash (hopefully) by either suspending single regions
318     wherever possible or if unavoidable whole engine(s)
319 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
320     policy and priority on thread level, set a minimum stack size for
321     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
322     threads simply inherited properties of starting thread instead of
323     setting their own policy and priority
324 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
325     main process did not wait for the stack trace process to finish
326     its output
327 persson 1248 - fixed some minor memory leaks
328 schoenebeck 1259 - reenabled assembly features support, at the moment only for
329     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
330 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
331     register, to avoid relocations in the text segment at runtime)
332 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
333 schoenebeck 947
334     * MIDI driver:
335     - dispatch bank select (MSB and LSB) messages
336    
337 schoenebeck 1049 * audio driver:
338     - the ALSA audio output driver parameters now reflect the correct
339     parameter value ranges for the respective selected sound card
340     (patch by Till Wimmer, a bit fixed and extended)
341    
342 persson 951 * Gigasampler format engine:
343     - if a filter is used and EG2 finishes before EG1, let the voice
344     die when EG2 has finished (this fixes a problem with clicks and
345     voice starvation for some gigs)
346 persson 1038 - playback is no longer disabled during instrument loading
347     - all notes playing on a channel that changes its instrument keep
348     playing with the old instrument until they get a note off
349     command
350 persson 1039 - EG fix: a release value of zero could cause noises or crash
351 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
352 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
353     above max sustain level, which means that there is a decay phase
354     even if sustain is 100%
355 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
356     noises or crashes
357 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
358 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
359     supplied to the configure script (fixes #46)
360 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
361     instead of a fix value
362 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
363     127 (solo mode) only kill voices if the respective mode really
364     changed
365 persson 951
366 schoenebeck 1244 * LSCP server:
367     - fixed compile time error for old Bison versions
368     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
369 schoenebeck 1245 - parser now supports extended ASCII character set
370     (up to ASCII code 255, i.e. includes now umlauts and accents)
371     - filename arguments in LSCP commands now allow to use escape
372     sequences, that is directly literal as one of: \', \", \\, \n, \r,
373     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
374     code value like \xf2) (fixes bug #24)
375 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
376     least one of their text-based parameters (i.e. name, description):
377     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
378     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
379     "SET DB_INSTRUMENT_DIRECTORY NAME",
380     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
381     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
382     "FIND DB_INSTRUMENT_DIRECTORIES"
383 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
384     occured, the unexpected character and the actually expected, possible
385     character(s), the latter only if less than 5 possibilities)
386 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale

388 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
389     of strings were treated as being one string containing commas
390     (fixes #57)
391 schoenebeck 1244
392 iliev 959 * Bug fixes:
393     - fixed crash occurring on certain LSCP scripts (Bug 39)
394 persson 1038 - another thread safety fix for lscp "load engine" and "set
395     channel audio output device"
396 iliev 1283 - fixed a crash which occurs when reassigning the same engine
397     on a sampler channel with connected MIDI device
398 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
399     device connected to a sampler channel to number less then or equal
400     to the index of the port to which the sampler channel is connected.
401 iliev 1296 - The previous bindings were not been disconnected when altering
402     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
403     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
404 iliev 1297 - The active stream/voice count statistic was incorrect.
405 iliev 1298 - notification events were not been sent for some sampler
406     channel changes
407 iliev 1305 - added default min and max values to restrict the number of allowed
408     audio output channels and MIDI input ports
409 iliev 1306 - the connection to the PCM interface is now closed when destroying
410     an audio output device
411 schoenebeck 1332 - files with slash in their path or filename could not be loaded
412 iliev 959
413 schoenebeck 1221 * test cases:
414     - updated and fixed (haven't been touched in a while)
415    
416 schoenebeck 937 Version 0.4.0 (24 November 2006)
417 persson 696
418 schoenebeck 697 * packaging changes:
419 capela 868 - changed deprecated copyright attribute to license; added ldconfig
420     to post-(un)install steps; added devel package for liblinuxsampler;
421     to linuxsampler.spec (RPM)
422 schoenebeck 697 - install necessary development header files for allowing 3rd party
423     applications to link against liblinuxsampler
424     - liblinuxsampler's API documentation can be generated with 'make docs'
425     (Doxygen required)
426 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
427     implementation (currently either an integer math solution or a
428     di-harmonic approximation), automatic detection can be overriden
429     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
430     configure script argument though (mandatory for cross-compilation)
431 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
432     provided some on his own (as CXXFLAGS)
433 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
434     messages
435 schoenebeck 852 - added compile time options to allow disabling the various audio and
436     MIDI drivers
437 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
438     (patch by Ebrahim Mayat)
439 schoenebeck 697
440 persson 696 * Gigasampler format engine:
441 schoenebeck 738 - extensive synthesis optimization
442     (reimplementation of EGs and LFO(s), removed synthesis parameter
443     prerendering and the synthesis parameter matrix in general, splitting
444     each audio fragment into subfragments now where each subfragment uses
445 persson 830 constant pitch and filter coefficients. The volume coefficient is
446     linearly interpolated inside a subfragment, unless
447     --disable-interpolate-volume is set.)
448 persson 696 - fine tuning of the EG modulation parameters
449 persson 729 - improved filter cutoff calculation by adding support for the
450     following gig parameters: Cutoff freq (used when no cutoff
451     controller is defined), Control invert, Minimum cutoff, Velocity
452 persson 791 curve and Velocity range. The keyboard tracking now scales
453     cutoff frequency instead of resonance.
454 persson 877 - added support for gig parameter Resonance.
455 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
456 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
457     which can be overridden with --enable-global-attenuation
458 persson 783 - EG fixes: made the length of "attack hold" stage more
459     accurate. Release stage can now start before attack stage
460 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
461     time now has a minimal value to prevent clicks.
462 persson 799 - fixed pitch changes larger than one octave
463 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
464     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
465     all modes can be altered via standard GM messages, that is CC5 for
466     altering portamento time, CC65 for enabling / disabling portamento
467     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
468 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
469     parameter) and crossfade
470 persson 831 - added support for the "attenuation controller threshold" gig
471     parameter
472 persson 832 - added smoothing of volume changes caused by control change
473     messages
474 persson 865 - sample loop parameters are now taken from the DimensionRegion
475     instead of the wave chunk
476     - fixed keyswitching for v3 gigs with a number of keyswitch splits
477     not equal to a power of two
478 persson 877 - reimplementation of the filter algorithm. The new filter is more
479     accurate and supports all gig filter types, including bandreject
480     and lowpass turbo.
481 persson 903 - real support for 24 bit samples - samples are not truncated to
482     16 bits anymore
483     - support for aftertouch (channel pressure, not polyphonic
484     aftertouch)
485 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
486     amplifying from 0)
487 persson 696
488 schoenebeck 711 * LSCP server:
489     - fixed application exit on broken pipe error (fixes bug #20)
490 iliev 793 - fixed the notification messages delay due to lack of
491     network activity (fixes bug #26)
492 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
493     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
494 schoenebeck 711
495 schoenebeck 838 * audio driver:
496     - added aRts audio output driver (by no means RT safe)
497    
498 schoenebeck 775 * MIDI driver:
499     - fixed legacy sysex code which caused dispatching of MIDI SysEx
500     messages several times instead of once
501 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
502     for events (i.e. for offline rendering based MIDI drivers)
503 persson 922 - added checks for bad MIDI data
504 schoenebeck 775
505 schoenebeck 900 * linuxsampler application:
506     - show available sampler engine types on startup
507    
508 schoenebeck 705 * general changes:
509     - support for muting sampler channels and solo mode of the same, two new
510     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
511     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
512     introduced for this, the behavior is the same like on a mixer console
513 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
514     --enable-process-muted-channels which can be used to enable the
515     processing of muted channels.
516 iliev 777 - support for sostenuto pedal
517 iliev 779 - support for monitoring the total number of active voices
518 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
519     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
520 persson 835 - fixed some memory management errors
521 persson 841 - fixed some concurrency problems that could lead to crashes when
522     LSCP commands were executed
523 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
524     sampler channel (fixes bug #36)
525 schoenebeck 705
526 schoenebeck 692 Version 0.3.3 (15 July 2005)
527 schoenebeck 686
528     * packaging changes:
529     - fixed compilation with gcc 4.0
530    
531 schoenebeck 687 * Gigasampler format engine:
532     - LFO preprocessing was performed even though the respective LFO was
533     disabled by the instrument patch (minor efficiency fix)
534 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
535     for volume ramp downs in the same fragment (needed for current voice
536     stealing implementation) then simply inform the user with a warning
537     about possible click sounds and reduce the volume ramp down
538     appropriately instead of cancelling the audio device connection
539 schoenebeck 687
540 schoenebeck 677 Version 0.3.2 (24 June 2005)
541 schoenebeck 609
542     * packaging changes:
543     - updated autotools build files to compile on OS X
544     (conditional compilation of CoreMIDI and MidiShare drivers)
545 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
546     './configure --disable-asm' (definitely not recommended)
547 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
548     - require automake (>= 1.5) for 'make -f Makefile.cvs'
549     (due to 'dist-bzip2' automake option)
550 schoenebeck 649
551     * Gigasampler format engine:
552     - support for the gig parameters for "release velocity response" curves
553     - fine tuning of the EGADSR envelope
554     - volume of release triggered samples now depends on note-on velocity,
555     note length and gig parameter "release trigger decay" instead of
556     note-off velocity.
557 schoenebeck 663 - revised voice stealing
558     (fixes crash and endless loop caused by voice stealing)
559 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
560 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
561     instead of when the respective voice is actually launched
562     (fixes undefined behavior if stolen voices belonged to a key group -
563     this case was followed by a "killed voice survived" error message)
564 schoenebeck 669 - fixed minor issue with null/silence samples
565     (those stole voices even though they don't need a voice at all which
566     resulted in "voice stealing didn't work out" messages)
567 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
568     instrument or audio output device change
569 schoenebeck 654
570 schoenebeck 620 * LSCP server:
571 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
572 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
573 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
574 schoenebeck 609
575 schoenebeck 668 * linuxsampler application:
576     - added command line parameters --lscp-addr and --lscp-port to override
577     default IP address and port of LSCP server
578    
579 schoenebeck 579 Version 0.3.1 (24 May 2005)
580    
581     * initial release
