* configure script fix: removed unconditional use of SSE

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

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 schoenebeck 1599
78 persson 1651 * MIDI driver:
79     - added JACK MIDI driver
80 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
81     want to (mis)use it for some purpose ("fixed" in all current MIDI
82     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
83 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
84 persson 1887 CoreMidi or AU
85 persson 1889 - fixed mingw-w64 compilation error in MME driver
86 persson 1651

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