* bugfix: two private structs had the same name, which could cause
  problems if the linker chose the wrong constructor

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