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 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)
86 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, 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 senoner 1911 works with both standalone mode and VST plugin.
101     the instruments DB file is located in
102     %USERPROFILE%\.linuxsampler\instruments.db which allows different
103     databases for each windows user
104 iliev 1603
105 persson 1644 * Gigasampler format engine:
106     - fixed a memory leak that could happen when a channel was deleted
107     while notes were playing
108 persson 1646 - made it possible to load an instrument even if the audio thread
109     isn't running
110 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
111     enough for piano gigs with pedal noise samples
112 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
113     respective FX send MIDI controller was used
114 schoenebeck 1724 - added support for GM global device volume SysEx message
115 schoenebeck 1762 (can be selected at compile time to either apply globally to the
116     whole sampler [default] or only to the sampler channels that are
117     connected to the respective MIDI input port the SysEx message arrived
118     on)
119 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
120     sometimes wrongly killed in the same buffer, causing no sound to
121     be played
122 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
123     which is usally used to switch a part between chromatic sounds and
124     drumkit sounds (as opposed to their common default setting of MIDI
125     part 10 being a drumkit part and all other ones chromatic parts), in
126     LS however one can switch between the first 16 MIDI instrument maps
127     defined for the sampler
128 persson 1764 - made it possible to create multiple sample channels even if the
129     audio thread isn't running
130 persson 1844 - fixed crash when removing channel with active voices (#116)
131 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
132     un-cache the respective sample if it's really not used by any
133     sampler engine anymore
134     - re-cache samples in case they were changed by an instrument editor,
135     e.g. when a sample was added while playing (#82)
136 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
137     same time stamp as the voice's note-on event and occured both in the
138     same audio fragment cycle (fixes bug #112)
139 persson 1858 - added support for the "fine tune" and "pitch bend range"
140     instrument-level gig parameters
141     - fixed minor artifacts in pitch bend handling
142 schoenebeck 1860 - added support for GS Reset SysEx message
143 persson 1862 - allow gig files to use unlimited downward pitch shifting
144     - added a limit check for upward pitch shifting
145 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
146     note was silent
147 persson 1644
148 schoenebeck 1687 * LSCP server:
149     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
150     react on MIDI data arriving on certain sampler channels (so far only
151     Note-On and Note-Off events are sent via this LSCP event)
152 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
153     react on MIDI data arriving on certain MIDI input devices (so far only
154     Note-On and Note-Off events are sent via this LSCP event)
155 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
156     SET DB_INSTRUMENT FILE_PATH
157 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
158     frontends to send MIDI messages to specific sampler channel
159     - added two additional fields to GET FILE INSTRUMENT INFO command -
160     KEY_BINDINGS and KEYSWITCH_BINDINGS
161 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
162     was incorrect
163 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
164 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
165     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
166     be triggered respectively
167     - added new LSCP command "SET STREAMS" to globally alter the maximum
168     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
169     which will be triggered respectively
170 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
171     a gigedit file dialog is opened)
172 iliev 1848 - close all connections when LSCPServer is deleted
173 iliev 1882 - hard close of all sockets on exit
174 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
175     driver
176 schoenebeck 1687
177 iliev 1761 * Bug fixes:
178     - fixed a crash which occurs when removing a sampler channel waiting
179     to start instrument loading after another channel
180 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
181     instrument loading in progress (bug #113)
182 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
183     instrument with PERSISTENT load mode
184 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
185     - fixed memory leaks when issuing the following LSCP commands:
186     GET AUDIO_OUTPUT_DRIVER INFO
187     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
188     GET MIDI_INPUT_DRIVER INFO
189     GET MIDI_INPUT_DRIVER_PARAMETER INFO
190     - fixed possible compilation error when sqlite is not present
191 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
192 iliev 1847 - fixed crash when changing the audio output device of a sampler
193     channel with loaded instrument and start playing notes
194 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
195 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
196     PowerPC, which probably could cause crashes on that platform
197 persson 1889 - fixed a memory management error which could cause a crash when a
198     plugin was unloaded
199 persson 1896 - bugfix: two private structs had the same name, which could cause
200     problems if the linker chose the wrong constructor
201 iliev 1761
202    
203 schoenebeck 1560 Version 0.5.1 (6 December 2007)
204 schoenebeck 1454
205     * packaging changes:
206     - added autoconf checks for pthread library
207     - added autoconf check for pthread bug found on certain NPTL-enabled
208     glibc versions (see Gentoo bug report #194076)
209 senoner 1502 - added autoconf checks for MS Windows
210 schoenebeck 1454
211 persson 1455 * general changes:
212     - bugfix: the thread used by an editor plugin didn't die when the
213     editor closed
214 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
215     out all the space. operator--() did not apply size_mask after
216     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
217     order to avoid problems with the _NonVolatileReader functions.
218     - bugfix: Stream.h: added a missing divide by BytesPerSample in
219     GetWriteSpace(). Since this function is currently only used in
220     the stream's qsort() compare function, it didn't trigger any
221     bugs.
222     - Resampler.h, Synthesizer.h: cubic interpolation now works in
223     24bit mode too. Faster method to read 24bit words on little
224     endian machines (x86): replaced 3 byte reads + shifts with a 1
225     unaligned 32bit read and shift
226     - experimental support for MS Windows (MIDI input via MME, AUDIO
227     output via ASIO)
228     - made handling of SIGINT signal (Ctrl-C) a bit more robust
229 iliev 1541 - support for monitoring the total number of active disk streams
230     (new LSCP commands: GET TOTAL_STREAM_COUNT,
231     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
232 persson 1455
233 senoner 1500 * AUDIO driver:
234 persson 1534 - added Windows ASIO low latency audio driver
235 senoner 1500
236 senoner 1485 * MIDI driver:
237 schoenebeck 1495 - added MME Windows MIDI driver
238 senoner 1485
239 schoenebeck 1471 * LSCP server:
240     - added support for Windows style path / filenames, however with
241     forward slash path separators instead of backslash
242     (i.e. "C:/foo/bar.gig")
243 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
244     apostrophes as well
245 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
246     "LIST FILE INSTRUMENTS <file>" and
247     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
248     about an arbitrary instrument file on the system where the sampler is
249     running on
250 schoenebeck 1471
251 schoenebeck 1424 Version 0.5.0 (15 October 2007)
252 schoenebeck 947
253 schoenebeck 1065 * packaging changes:
254 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
255     API header files anymore
256 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
257     the Doxygen API documentation (explicitly listed in Doxyfile.in)
258 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
259     capable to execute our autoconf environment, thus no need anymore
260     to maintain the compile time configuration file (osx/version.h) for
261     OSX manually (patch by Toshi Nagata)
262 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
263     parameters
264 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
265     C++ API header files, all implementation internal global definitions
266     are now in global_private.h
267     - atomic.h is not exposed to the C++ API anymore
268     - no need to include config.h anymore for using LS's API header files
269     - fixed warnings in API doc generation
270 schoenebeck 1065
271 schoenebeck 947 * general changes:
272     - replaced the old, confusing MIDI program change mechanism by a
273     flexible MIDI instrument mapper which allows to map arbitrary
274 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
275 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
276     loaded on the respective channel when such MIDI program change
277     messages arrive, beside that, each entry allows to define a life-time
278     strategy for the instrument, so the user can define whether the
279     instrument should i.e. be permanently loaded (to be able to switch
280     quickly among sounds) or i.e. loaded just on demand when the
281     respective program change arrives (to safe RAM space), as well as a
282     global volume factor for each entry, so the user can adjust the volume
283     dynamic of his mapped instrument collection without having to modify
284 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
285     MIDI instrument maps and assign each sampler channel individually
286     a certain map, so that i.e. separation of normal instruments and
287     drumkits is possible
288 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
289     MIDI instrument maps, MIDI instruments, FX sends, global volume.
290 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
291     due to a constant size RingBuffer FIFO which is now replaced by a
292     dynamic (unlimited) size std::list FIFO
293 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
294     output channels for being processed by external effect processors
295     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
296     controllers
297 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
298 iliev 1130 - Implemented new, improved notification system
299 schoenebeck 1149 - fixed compilation errors regarding OSX
300     (patch by Toshi Nagata)
301 iliev 1161 - implemented instruments database
302 iliev 1345 - added support for escape sequences to the instruments database
303 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
304     within the sampler's process (by using instrument editor plugins),
305     you'll notice the new "Registered instrument editors:" message on
306 schoenebeck 1407 startup, added a new LSCP command:
307     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
308 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
309     given sampler channel, the plugin path can be overridden at compile
310     time with ./configure --enable-plugin-dir=/some/dir
311 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
312     in the sampler's process to safely edit instruments while playing
313     without a crash (hopefully) by either suspending single regions
314     wherever possible or if unavoidable whole engine(s)
315 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
316     policy and priority on thread level, set a minimum stack size for
317     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
318     threads simply inherited properties of starting thread instead of
319     setting their own policy and priority
320 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
321     main process did not wait for the stack trace process to finish
322     its output
323 persson 1248 - fixed some minor memory leaks
324 schoenebeck 1259 - reenabled assembly features support, at the moment only for
325     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
326 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
327     register, to avoid relocations in the text segment at runtime)
328 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
329 schoenebeck 947
330     * MIDI driver:
331     - dispatch bank select (MSB and LSB) messages
332    
333 schoenebeck 1049 * audio driver:
334     - the ALSA audio output driver parameters now reflect the correct
335     parameter value ranges for the respective selected sound card
336     (patch by Till Wimmer, a bit fixed and extended)
337    
338 persson 951 * Gigasampler format engine:
339     - if a filter is used and EG2 finishes before EG1, let the voice
340     die when EG2 has finished (this fixes a problem with clicks and
341     voice starvation for some gigs)
342 persson 1038 - playback is no longer disabled during instrument loading
343     - all notes playing on a channel that changes its instrument keep
344     playing with the old instrument until they get a note off
345     command
346 persson 1039 - EG fix: a release value of zero could cause noises or crash
347 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
348 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
349     above max sustain level, which means that there is a decay phase
350     even if sustain is 100%
351 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
352     noises or crashes
353 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
354 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
355     supplied to the configure script (fixes #46)
356 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
357     instead of a fix value
358 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
359     127 (solo mode) only kill voices if the respective mode really
360     changed
361 persson 951
362 schoenebeck 1244 * LSCP server:
363     - fixed compile time error for old Bison versions
364     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
365 schoenebeck 1245 - parser now supports extended ASCII character set
366     (up to ASCII code 255, i.e. includes now umlauts and accents)
367     - filename arguments in LSCP commands now allow to use escape
368     sequences, that is directly literal as one of: \', \", \\, \n, \r,
369     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
370     code value like \xf2) (fixes bug #24)
371 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
372     least one of their text-based parameters (i.e. name, description):
373     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
374     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
375     "SET DB_INSTRUMENT_DIRECTORY NAME",
376     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
377     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
378     "FIND DB_INSTRUMENT_DIRECTORIES"
379 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
380     occured, the unexpected character and the actually expected, possible
381     character(s), the latter only if less than 5 possibilities)
382 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
383     settings
384 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
385     of strings were treated as being one string containing commas
386     (fixes #57)
387 schoenebeck 1244
388 iliev 959 * Bug fixes:
389     - fixed crash occurring on certain LSCP scripts (Bug 39)
390 persson 1038 - another thread safety fix for lscp "load engine" and "set
391     channel audio output device"
392 iliev 1283 - fixed a crash which occurs when reassigning the same engine
393     on a sampler channel with connected MIDI device
394 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
395     device connected to a sampler channel to number less then or equal
396     to the index of the port to which the sampler channel is connected.
397 iliev 1296 - The previous bindings were not been disconnected when altering
398     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
399     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
400 iliev 1297 - The active stream/voice count statistic was incorrect.
401 iliev 1298 - notification events were not been sent for some sampler
402     channel changes
403 iliev 1305 - added default min and max values to restrict the number of allowed
404     audio output channels and MIDI input ports
405 iliev 1306 - the connection to the PCM interface is now closed when destroying
406     an audio output device
407 schoenebeck 1332 - files with slash in their path or filename could not be loaded
408 iliev 959
409 schoenebeck 1221 * test cases:
410     - updated and fixed (haven't been touched in a while)
411    
412 schoenebeck 937 Version 0.4.0 (24 November 2006)
413 persson 696
414 schoenebeck 697 * packaging changes:
415 capela 868 - changed deprecated copyright attribute to license; added ldconfig
416     to post-(un)install steps; added devel package for liblinuxsampler;
417     to linuxsampler.spec (RPM)
418 schoenebeck 697 - install necessary development header files for allowing 3rd party
419     applications to link against liblinuxsampler
420     - liblinuxsampler's API documentation can be generated with 'make docs'
421     (Doxygen required)
422 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
423     implementation (currently either an integer math solution or a
424     di-harmonic approximation), automatic detection can be overriden
425     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
426     configure script argument though (mandatory for cross-compilation)
427 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
428     provided some on his own (as CXXFLAGS)
429 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
430     messages
431 schoenebeck 852 - added compile time options to allow disabling the various audio and
432     MIDI drivers
433 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
434     (patch by Ebrahim Mayat)
435 schoenebeck 697
436 persson 696 * Gigasampler format engine:
437 schoenebeck 738 - extensive synthesis optimization
438     (reimplementation of EGs and LFO(s), removed synthesis parameter
439     prerendering and the synthesis parameter matrix in general, splitting
440     each audio fragment into subfragments now where each subfragment uses
441 persson 830 constant pitch and filter coefficients. The volume coefficient is
442     linearly interpolated inside a subfragment, unless
443     --disable-interpolate-volume is set.)
444 persson 696 - fine tuning of the EG modulation parameters
445 persson 729 - improved filter cutoff calculation by adding support for the
446     following gig parameters: Cutoff freq (used when no cutoff
447     controller is defined), Control invert, Minimum cutoff, Velocity
448 persson 791 curve and Velocity range. The keyboard tracking now scales
449     cutoff frequency instead of resonance.
450 persson 877 - added support for gig parameter Resonance.
451 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
452 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
453     which can be overridden with --enable-global-attenuation
454 persson 783 - EG fixes: made the length of "attack hold" stage more
455     accurate. Release stage can now start before attack stage
456 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
457     time now has a minimal value to prevent clicks.
458 persson 799 - fixed pitch changes larger than one octave
459 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
460     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
461     all modes can be altered via standard GM messages, that is CC5 for
462     altering portamento time, CC65 for enabling / disabling portamento
463     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
464 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
465     parameter) and crossfade
466 persson 831 - added support for the "attenuation controller threshold" gig
467     parameter
468 persson 832 - added smoothing of volume changes caused by control change
469     messages
470 persson 865 - sample loop parameters are now taken from the DimensionRegion
471     instead of the wave chunk
472     - fixed keyswitching for v3 gigs with a number of keyswitch splits
473     not equal to a power of two
474 persson 877 - reimplementation of the filter algorithm. The new filter is more
475     accurate and supports all gig filter types, including bandreject
476     and lowpass turbo.
477 persson 903 - real support for 24 bit samples - samples are not truncated to
478     16 bits anymore
479     - support for aftertouch (channel pressure, not polyphonic
480     aftertouch)
481 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
482     amplifying from 0)
483 persson 696
484 schoenebeck 711 * LSCP server:
485     - fixed application exit on broken pipe error (fixes bug #20)
486 iliev 793 - fixed the notification messages delay due to lack of
487     network activity (fixes bug #26)
488 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
489     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
490 schoenebeck 711
491 schoenebeck 838 * audio driver:
492     - added aRts audio output driver (by no means RT safe)
493    
494 schoenebeck 775 * MIDI driver:
495     - fixed legacy sysex code which caused dispatching of MIDI SysEx
496     messages several times instead of once
497 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
498     for events (i.e. for offline rendering based MIDI drivers)
499 persson 922 - added checks for bad MIDI data
500 schoenebeck 775
501 schoenebeck 900 * linuxsampler application:
502     - show available sampler engine types on startup
503    
504 schoenebeck 705 * general changes:
505     - support for muting sampler channels and solo mode of the same, two new
506     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
507     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
508     introduced for this, the behavior is the same like on a mixer console
509 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
510     --enable-process-muted-channels which can be used to enable the
511     processing of muted channels.
512 iliev 777 - support for sostenuto pedal
513 iliev 779 - support for monitoring the total number of active voices
514 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
515     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
516 persson 835 - fixed some memory management errors
517 persson 841 - fixed some concurrency problems that could lead to crashes when
518     LSCP commands were executed
519 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
520     sampler channel (fixes bug #36)
521 schoenebeck 705
522 schoenebeck 692 Version 0.3.3 (15 July 2005)
523 schoenebeck 686
524     * packaging changes:
525     - fixed compilation with gcc 4.0
526    
527 schoenebeck 687 * Gigasampler format engine:
528     - LFO preprocessing was performed even though the respective LFO was
529     disabled by the instrument patch (minor efficiency fix)
530 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
531     for volume ramp downs in the same fragment (needed for current voice
532     stealing implementation) then simply inform the user with a warning
533     about possible click sounds and reduce the volume ramp down
534     appropriately instead of cancelling the audio device connection
535 schoenebeck 687
536 schoenebeck 677 Version 0.3.2 (24 June 2005)
537 schoenebeck 609
538     * packaging changes:
539     - updated autotools build files to compile on OS X
540     (conditional compilation of CoreMIDI and MidiShare drivers)
541 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
542     './configure --disable-asm' (definitely not recommended)
543 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
544     - require automake (>= 1.5) for 'make -f Makefile.cvs'
545     (due to 'dist-bzip2' automake option)
546 schoenebeck 649
547     * Gigasampler format engine:
548     - support for the gig parameters for "release velocity response" curves
549     - fine tuning of the EGADSR envelope
550     - volume of release triggered samples now depends on note-on velocity,
551     note length and gig parameter "release trigger decay" instead of
552     note-off velocity.
553 schoenebeck 663 - revised voice stealing
554     (fixes crash and endless loop caused by voice stealing)
555 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
556 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
557     instead of when the respective voice is actually launched
558     (fixes undefined behavior if stolen voices belonged to a key group -
559     this case was followed by a "killed voice survived" error message)
560 schoenebeck 669 - fixed minor issue with null/silence samples
561     (those stole voices even though they don't need a voice at all which
562     resulted in "voice stealing didn't work out" messages)
563 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
564     instrument or audio output device change
565 schoenebeck 654
566 schoenebeck 620 * LSCP server:
567 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
568 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
569 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
570 schoenebeck 609
571 schoenebeck 668 * linuxsampler application:
572     - added command line parameters --lscp-addr and --lscp-port to override
573     default IP address and port of LSCP server
574    
575 schoenebeck 579 Version 0.3.1 (24 May 2005)
576    
577     * initial release
