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

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 schoenebeck 1599
81 persson 1651 * MIDI driver:
82     - added JACK MIDI driver
83 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
84     want to (mis)use it for some purpose ("fixed" in all current MIDI
85     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)

87 persson 1887 CoreMidi or AU
88 persson 1889 - fixed mingw-w64 compilation error in MME driver
89 persson 1651
90 schoenebeck 1604 * instruments database:
91 iliev 1603 - avoid time consuming samples scanning when adding instruments
92     to the instruments database
93 iliev 1727 - added support for handling lost files in the instruments database
94 iliev 1781 - Implemented option for adding instruments in separate directories
95     in the instruments database

97 persson 1908 - work-around for missing fnmatch function on Windows to make
98     instrument database compilable
99 senoner 1910 - added instrument database support on Windows
100     relative file path for instruments db in order to work in both
101     standalone and VST similar to the editor plugins still need to
102     be implemented
103 iliev 1603
104 persson 1644 * Gigasampler format engine:
105     - fixed a memory leak that could happen when a channel was deleted
106     while notes were playing
107 persson 1646 - made it possible to load an instrument even if the audio thread
108     isn't running
109 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
110     enough for piano gigs with pedal noise samples
111 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
112     respective FX send MIDI controller was used
113 schoenebeck 1724 - added support for GM global device volume SysEx message
114 schoenebeck 1762 (can be selected at compile time to either apply globally to the
115     whole sampler [default] or only to the sampler channels that are
116     connected to the respective MIDI input port the SysEx message arrived
117     on)
118 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
119     sometimes wrongly killed in the same buffer, causing no sound to
120     be played
121 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
122     which is usally used to switch a part between chromatic sounds and
123     drumkit sounds (as opposed to their common default setting of MIDI
124     part 10 being a drumkit part and all other ones chromatic parts), in
125     LS however one can switch between the first 16 MIDI instrument maps
126     defined for the sampler
127 persson 1764 - made it possible to create multiple sample channels even if the
128     audio thread isn't running
129 persson 1844 - fixed crash when removing channel with active voices (#116)
130 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
131     un-cache the respective sample if it's really not used by any
132     sampler engine anymore
133     - re-cache samples in case they were changed by an instrument editor,
134     e.g. when a sample was added while playing (#82)
135 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
136     same time stamp as the voice's note-on event and occured both in the
137     same audio fragment cycle (fixes bug #112)
138 persson 1858 - added support for the "fine tune" and "pitch bend range"
139     instrument-level gig parameters
140     - fixed minor artifacts in pitch bend handling
141 schoenebeck 1860 - added support for GS Reset SysEx message
142 persson 1862 - allow gig files to use unlimited downward pitch shifting
143     - added a limit check for upward pitch shifting
144 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
145     note was silent
146 persson 1644
147 schoenebeck 1687 * LSCP server:
148     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
149     react on MIDI data arriving on certain sampler channels (so far only
150     Note-On and Note-Off events are sent via this LSCP event)
151 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
152     react on MIDI data arriving on certain MIDI input devices (so far only
153     Note-On and Note-Off events are sent via this LSCP event)
154 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
155     SET DB_INSTRUMENT FILE_PATH
156 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
157     frontends to send MIDI messages to specific sampler channel
158     - added two additional fields to GET FILE INSTRUMENT INFO command -
159     KEY_BINDINGS and KEYSWITCH_BINDINGS
160 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
161     was incorrect
162 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
163 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
164     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
165     be triggered respectively
166     - added new LSCP command "SET STREAMS" to globally alter the maximum
167     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
168     which will be triggered respectively
169 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
170     a gigedit file dialog is opened)
171 iliev 1848 - close all connections when LSCPServer is deleted
172 iliev 1882 - hard close of all sockets on exit
173 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
174     driver
175 schoenebeck 1687
176 iliev 1761 * Bug fixes:
177     - fixed a crash which occurs when removing a sampler channel waiting
178     to start instrument loading after another channel
179 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
180     instrument loading in progress (bug #113)
181 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
182     instrument with PERSISTENT load mode
183 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
184     - fixed memory leaks when issuing the following LSCP commands:
185     GET AUDIO_OUTPUT_DRIVER INFO
186     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
187     GET MIDI_INPUT_DRIVER INFO
188     GET MIDI_INPUT_DRIVER_PARAMETER INFO
189     - fixed possible compilation error when sqlite is not present
190 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
191 iliev 1847 - fixed crash when changing the audio output device of a sampler
192     channel with loaded instrument and start playing notes
193 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
194 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
195     PowerPC, which probably could cause crashes on that platform
196 persson 1889 - fixed a memory management error which could cause a crash when a
197     plugin was unloaded
198 persson 1896 - bugfix: two private structs had the same name, which could cause
199     problems if the linker chose the wrong constructor
200 iliev 1761
201    
202 schoenebeck 1560 Version 0.5.1 (6 December 2007)
203 schoenebeck 1454
204     * packaging changes:
205     - added autoconf checks for pthread library
206     - added autoconf check for pthread bug found on certain NPTL-enabled
207     glibc versions (see Gentoo bug report #194076)
208 senoner 1502 - added autoconf checks for MS Windows
209 schoenebeck 1454
210 persson 1455 * general changes:
211     - bugfix: the thread used by an editor plugin didn't die when the
212     editor closed
213 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
214     out all the space. operator--() did not apply size_mask after
215     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
216     order to avoid problems with the _NonVolatileReader functions.
217     - bugfix: Stream.h: added a missing divide by BytesPerSample in
218     GetWriteSpace(). Since this function is currently only used in
219     the stream's qsort() compare function, it didn't trigger any
220     bugs.
221     - Resampler.h, Synthesizer.h: cubic interpolation now works in
222     24bit mode too. Faster method to read 24bit words on little
223     endian machines (x86): replaced 3 byte reads + shifts with a 1
224     unaligned 32bit read and shift
225     - experimental support for MS Windows (MIDI input via MME, AUDIO
226     output via ASIO)
227     - made handling of SIGINT signal (Ctrl-C) a bit more robust
228 iliev 1541 - support for monitoring the total number of active disk streams
229     (new LSCP commands: GET TOTAL_STREAM_COUNT,
230     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
231 persson 1455
232 senoner 1500 * AUDIO driver:
233 persson 1534 - added Windows ASIO low latency audio driver
234 senoner 1500
235 senoner 1485 * MIDI driver:
236 schoenebeck 1495 - added MME Windows MIDI driver
237 senoner 1485
238 schoenebeck 1471 * LSCP server:
239     - added support for Windows style path / filenames, however with
240     forward slash path separators instead of backslash
241     (i.e. "C:/foo/bar.gig")
242 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
243     apostrophes as well
244 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
245     "LIST FILE INSTRUMENTS <file>" and
246     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
247     about an arbitrary instrument file on the system where the sampler is
248     running on
249 schoenebeck 1471
250 schoenebeck 1424 Version 0.5.0 (15 October 2007)
251 schoenebeck 947
252 schoenebeck 1065 * packaging changes:
253 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
254     API header files anymore
255 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
256     the Doxygen API documentation (explicitly listed in Doxyfile.in)
257 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
258     capable to execute our autoconf environment, thus no need anymore
259     to maintain the compile time configuration file (osx/version.h) for
260     OSX manually (patch by Toshi Nagata)
261 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
262     parameters
263 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
264     C++ API header files, all implementation internal global definitions
265     are now in global_private.h
266     - atomic.h is not exposed to the C++ API anymore
267     - no need to include config.h anymore for using LS's API header files
268     - fixed warnings in API doc generation
269 schoenebeck 1065
270 schoenebeck 947 * general changes:
271     - replaced the old, confusing MIDI program change mechanism by a
272     flexible MIDI instrument mapper which allows to map arbitrary
273 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
274 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
275     loaded on the respective channel when such MIDI program change
276     messages arrive, beside that, each entry allows to define a life-time
277     strategy for the instrument, so the user can define whether the
278     instrument should i.e. be permanently loaded (to be able to switch
279     quickly among sounds) or i.e. loaded just on demand when the
280     respective program change arrives (to safe RAM space), as well as a
281     global volume factor for each entry, so the user can adjust the volume
282     dynamic of his mapped instrument collection without having to modify
283 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
284     MIDI instrument maps and assign each sampler channel individually
285     a certain map, so that i.e. separation of normal instruments and
286     drumkits is possible
287 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
288     MIDI instrument maps, MIDI instruments, FX sends, global volume.
289 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
290     due to a constant size RingBuffer FIFO which is now replaced by a
291     dynamic (unlimited) size std::list FIFO
292 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
293     output channels for being processed by external effect processors
294     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
295     controllers
296 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
297 iliev 1130 - Implemented new, improved notification system
298 schoenebeck 1149 - fixed compilation errors regarding OSX
299     (patch by Toshi Nagata)
300 iliev 1161 - implemented instruments database
301 iliev 1345 - added support for escape sequences to the instruments database
302 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
303     within the sampler's process (by using instrument editor plugins),
304     you'll notice the new "Registered instrument editors:" message on
305 schoenebeck 1407 startup, added a new LSCP command:
306     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
307 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
308     given sampler channel, the plugin path can be overridden at compile
309     time with ./configure --enable-plugin-dir=/some/dir
310 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
311     in the sampler's process to safely edit instruments while playing
312     without a crash (hopefully) by either suspending single regions
313     wherever possible or if unavoidable whole engine(s)
314 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
315     policy and priority on thread level, set a minimum stack size for
316     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
317     threads simply inherited properties of starting thread instead of
318     setting their own policy and priority
319 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
320     main process did not wait for the stack trace process to finish
321     its output
322 persson 1248 - fixed some minor memory leaks
323 schoenebeck 1259 - reenabled assembly features support, at the moment only for
324     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
325 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
326     register, to avoid relocations in the text segment at runtime)
327 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
328 schoenebeck 947
329     * MIDI driver:
330     - dispatch bank select (MSB and LSB) messages
331    
332 schoenebeck 1049 * audio driver:
333     - the ALSA audio output driver parameters now reflect the correct
334     parameter value ranges for the respective selected sound card
335     (patch by Till Wimmer, a bit fixed and extended)
336    
337 persson 951 * Gigasampler format engine:
338     - if a filter is used and EG2 finishes before EG1, let the voice
339     die when EG2 has finished (this fixes a problem with clicks and
340     voice starvation for some gigs)
341 persson 1038 - playback is no longer disabled during instrument loading
342     - all notes playing on a channel that changes its instrument keep
343     playing with the old instrument until they get a note off
344     command
345 persson 1039 - EG fix: a release value of zero could cause noises or crash
346 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
347 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
348     above max sustain level, which means that there is a decay phase
349     even if sustain is 100%
350 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
351     noises or crashes
352 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
353 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
354     supplied to the configure script (fixes #46)
355 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
356     instead of a fix value
357 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
358     127 (solo mode) only kill voices if the respective mode really
359     changed
360 persson 951
361 schoenebeck 1244 * LSCP server:
362     - fixed compile time error for old Bison versions
363     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
364 schoenebeck 1245 - parser now supports extended ASCII character set
365     (up to ASCII code 255, i.e. includes now umlauts and accents)
366     - filename arguments in LSCP commands now allow to use escape
367     sequences, that is directly literal as one of: \', \", \\, \n, \r,
368     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
369     code value like \xf2) (fixes bug #24)
370 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
371     least one of their text-based parameters (i.e. name, description):
372     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
373     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
374     "SET DB_INSTRUMENT_DIRECTORY NAME",
375     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
376     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
377     "FIND DB_INSTRUMENT_DIRECTORIES"
378 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
379     occured, the unexpected character and the actually expected, possible
380     character(s), the latter only if less than 5 possibilities)
381 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
382     settings
383 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
384     of strings were treated as being one string containing commas
385     (fixes #57)
386 schoenebeck 1244
387 iliev 959 * Bug fixes:
388     - fixed crash occurring on certain LSCP scripts (Bug 39)
389 persson 1038 - another thread safety fix for lscp "load engine" and "set
390     channel audio output device"
391 iliev 1283 - fixed a crash which occurs when reassigning the same engine
392     on a sampler channel with connected MIDI device
393 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
394     device connected to a sampler channel to number less then or equal
395     to the index of the port to which the sampler channel is connected.
396 iliev 1296 - The previous bindings were not been disconnected when altering
397     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
398     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
399 iliev 1297 - The active stream/voice count statistic was incorrect.
400 iliev 1298 - notification events were not been sent for some sampler
401     channel changes
402 iliev 1305 - added default min and max values to restrict the number of allowed
403     audio output channels and MIDI input ports
404 iliev 1306 - the connection to the PCM interface is now closed when destroying
405     an audio output device
406 schoenebeck 1332 - files with slash in their path or filename could not be loaded
407 iliev 959
408 schoenebeck 1221 * test cases:
409     - updated and fixed (haven't been touched in a while)
410    
411 schoenebeck 937 Version 0.4.0 (24 November 2006)
412 persson 696
413 schoenebeck 697 * packaging changes:
414 capela 868 - changed deprecated copyright attribute to license; added ldconfig
415     to post-(un)install steps; added devel package for liblinuxsampler;
416     to linuxsampler.spec (RPM)
417 schoenebeck 697 - install necessary development header files for allowing 3rd party
418     applications to link against liblinuxsampler
419     - liblinuxsampler's API documentation can be generated with 'make docs'
420     (Doxygen required)
421 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
422     implementation (currently either an integer math solution or a
423     di-harmonic approximation), automatic detection can be overriden
424     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
425     configure script argument though (mandatory for cross-compilation)
426 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
427     provided some on his own (as CXXFLAGS)
428 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
429     messages
430 schoenebeck 852 - added compile time options to allow disabling the various audio and
431     MIDI drivers
432 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
433     (patch by Ebrahim Mayat)
434 schoenebeck 697
435 persson 696 * Gigasampler format engine:
436 schoenebeck 738 - extensive synthesis optimization
437     (reimplementation of EGs and LFO(s), removed synthesis parameter
438     prerendering and the synthesis parameter matrix in general, splitting
439     each audio fragment into subfragments now where each subfragment uses
440 persson 830 constant pitch and filter coefficients. The volume coefficient is
441     linearly interpolated inside a subfragment, unless
442     --disable-interpolate-volume is set.)
443 persson 696 - fine tuning of the EG modulation parameters
444 persson 729 - improved filter cutoff calculation by adding support for the
445     following gig parameters: Cutoff freq (used when no cutoff
446     controller is defined), Control invert, Minimum cutoff, Velocity
447 persson 791 curve and Velocity range. The keyboard tracking now scales
448     cutoff frequency instead of resonance.
449 persson 877 - added support for gig parameter Resonance.
450 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
451 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
452     which can be overridden with --enable-global-attenuation
453 persson 783 - EG fixes: made the length of "attack hold" stage more
454     accurate. Release stage can now start before attack stage
455 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
456     time now has a minimal value to prevent clicks.
457 persson 799 - fixed pitch changes larger than one octave
458 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
459     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
460     all modes can be altered via standard GM messages, that is CC5 for
461     altering portamento time, CC65 for enabling / disabling portamento
462     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
463 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
464     parameter) and crossfade
465 persson 831 - added support for the "attenuation controller threshold" gig
466     parameter
467 persson 832 - added smoothing of volume changes caused by control change
468     messages
469 persson 865 - sample loop parameters are now taken from the DimensionRegion
470     instead of the wave chunk
471     - fixed keyswitching for v3 gigs with a number of keyswitch splits
472     not equal to a power of two
473 persson 877 - reimplementation of the filter algorithm. The new filter is more
474     accurate and supports all gig filter types, including bandreject
475     and lowpass turbo.
476 persson 903 - real support for 24 bit samples - samples are not truncated to
477     16 bits anymore
478     - support for aftertouch (channel pressure, not polyphonic
479     aftertouch)
480 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
481     amplifying from 0)
482 persson 696
483 schoenebeck 711 * LSCP server:
484     - fixed application exit on broken pipe error (fixes bug #20)
485 iliev 793 - fixed the notification messages delay due to lack of
486     network activity (fixes bug #26)
487 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
488     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
489 schoenebeck 711
490 schoenebeck 838 * audio driver:
491     - added aRts audio output driver (by no means RT safe)
492    
493 schoenebeck 775 * MIDI driver:
494     - fixed legacy sysex code which caused dispatching of MIDI SysEx
495     messages several times instead of once
496 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
497     for events (i.e. for offline rendering based MIDI drivers)
498 persson 922 - added checks for bad MIDI data
499 schoenebeck 775
500 schoenebeck 900 * linuxsampler application:
501     - show available sampler engine types on startup
502    
503 schoenebeck 705 * general changes:
504     - support for muting sampler channels and solo mode of the same, two new
505     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
506     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
507     introduced for this, the behavior is the same like on a mixer console
508 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
509     --enable-process-muted-channels which can be used to enable the
510     processing of muted channels.
511 iliev 777 - support for sostenuto pedal
512 iliev 779 - support for monitoring the total number of active voices
513 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
514     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
515 persson 835 - fixed some memory management errors
516 persson 841 - fixed some concurrency problems that could lead to crashes when
517     LSCP commands were executed
518 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
519     sampler channel (fixes bug #36)
520 schoenebeck 705
521 schoenebeck 692 Version 0.3.3 (15 July 2005)
522 schoenebeck 686
523     * packaging changes:
524     - fixed compilation with gcc 4.0
525    
526 schoenebeck 687 * Gigasampler format engine:
527     - LFO preprocessing was performed even though the respective LFO was
528     disabled by the instrument patch (minor efficiency fix)
529 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
530     for volume ramp downs in the same fragment (needed for current voice
531     stealing implementation) then simply inform the user with a warning
532     about possible click sounds and reduce the volume ramp down
533     appropriately instead of cancelling the audio device connection
534 schoenebeck 687
535 schoenebeck 677 Version 0.3.2 (24 June 2005)
536 schoenebeck 609
537     * packaging changes:
538     - updated autotools build files to compile on OS X
539     (conditional compilation of CoreMIDI and MidiShare drivers)
540 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
541     './configure --disable-asm' (definitely not recommended)
542 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
543     - require automake (>= 1.5) for 'make -f Makefile.cvs'
544     (due to 'dist-bzip2' automake option)
545 schoenebeck 649
546     * Gigasampler format engine:
547     - support for the gig parameters for "release velocity response" curves
548     - fine tuning of the EGADSR envelope
549     - volume of release triggered samples now depends on note-on velocity,
550     note length and gig parameter "release trigger decay" instead of
551     note-off velocity.
552 schoenebeck 663 - revised voice stealing
553     (fixes crash and endless loop caused by voice stealing)
554 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
555 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
556     instead of when the respective voice is actually launched
557     (fixes undefined behavior if stolen voices belonged to a key group -
558     this case was followed by a "killed voice survived" error message)
559 schoenebeck 669 - fixed minor issue with null/silence samples
560     (those stole voices even though they don't need a voice at all which
561     resulted in "voice stealing didn't work out" messages)
562 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
563     instrument or audio output device change
564 schoenebeck 654
565 schoenebeck 620 * LSCP server:
566 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
567 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
568 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
569 schoenebeck 609
570 schoenebeck 668 * linuxsampler application:
571     - added command line parameters --lscp-addr and --lscp-port to override
572     default IP address and port of LSCP server
573    
574 schoenebeck 579 Version 0.3.1 (24 May 2005)
575    
576     * initial release
