* added JACK MIDI driver

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    
9 schoenebeck 1601 * general changes:
10     - bugfix: on some POSIX systems instrument editor plugins refused to
11     load as we used a non-portable Linux specific struct field
12     (fixes bug #70, patch by Ronald Baljeu)
13 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
14     plugin DLL on Windows systems failed
15 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded
16     - optimized the SynchronizedConfig class so it doesn't wait
17     unnecessarily long after an update
18 schoenebeck 1601
19 schoenebeck 1599 * audio driver:
20     - removed the nonsense audio channel constraint (which was hard coded to
21     max. 100 audio channels) for most audio drivers
22 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
23     opposed to the LSCP specs
24 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
25     reflected the wrong value
26 persson 1644 - fixed a memory management bug in ASIO driver
27 schoenebeck 1599
28 persson 1651 * MIDI driver:
29     - added JACK MIDI driver
30    
31 schoenebeck 1604 * instruments database:
32 iliev 1603 - avoid time consuming samples scanning when adding instruments
33     to the instruments database
34    
35 persson 1644 * Gigasampler format engine:
36     - fixed a memory leak that could happen when a channel was deleted
37     while notes were playing
38 persson 1646 - made it possible to load an instrument even if the audio thread
39     isn't running
40 persson 1644
41 schoenebeck 1560 Version 0.5.1 (6 December 2007)
42 schoenebeck 1454
43     * packaging changes:
44     - added autoconf checks for pthread library
45     - added autoconf check for pthread bug found on certain NPTL-enabled
46     glibc versions (see Gentoo bug report #194076)
47 senoner 1502 - added autoconf checks for MS Windows
48 schoenebeck 1454
49 persson 1455 * general changes:
50     - bugfix: the thread used by an editor plugin didn't die when the
51     editor closed
52 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
53     out all the space. operator--() did not apply size_mask after
54     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
55     order to avoid problems with the _NonVolatileReader functions.
56     - bugfix: Stream.h: added a missing divide by BytesPerSample in
57     GetWriteSpace(). Since this function is currently only used in
58     the stream's qsort() compare function, it didn't trigger any
59     bugs.
60     - Resampler.h, Synthesizer.h: cubic interpolation now works in
61     24bit mode too. Faster method to read 24bit words on little
62     endian machines (x86): replaced 3 byte reads + shifts with a 1
63     unaligned 32bit read and shift
64     - experimental support for MS Windows (MIDI input via MME, AUDIO
65     output via ASIO)
66     - made handling of SIGINT signal (Ctrl-C) a bit more robust
67 iliev 1541 - support for monitoring the total number of active disk streams
68     (new LSCP commands: GET TOTAL_STREAM_COUNT,
69     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
70 persson 1455
71 senoner 1500 * AUDIO driver:
72 persson 1534 - added Windows ASIO low latency audio driver
73 senoner 1500
74 senoner 1485 * MIDI driver:
75 schoenebeck 1495 - added MME Windows MIDI driver
76 senoner 1485
77 schoenebeck 1471 * LSCP server:
78     - added support for Windows style path / filenames, however with
79     forward slash path separators instead of backslash
80     (i.e. "C:/foo/bar.gig")
81 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
82     apostrophes as well
83 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
84     "LIST FILE INSTRUMENTS <file>" and
85     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
86     about an arbitrary instrument file on the system where the sampler is
87     running on
88 schoenebeck 1471
89 schoenebeck 1424 Version 0.5.0 (15 October 2007)
90 schoenebeck 947
91 schoenebeck 1065 * packaging changes:
92 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
93     API header files anymore
94 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
95     the Doxygen API documentation (explicitly listed in Doxyfile.in)
96 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
97     capable to execute our autoconf environment, thus no need anymore
98     to maintain the compile time configuration file (osx/version.h) for
99     OSX manually (patch by Toshi Nagata)
100 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
101     parameters
102 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
103     C++ API header files, all implementation internal global definitions
104     are now in global_private.h
105     - atomic.h is not exposed to the C++ API anymore
106     - no need to include config.h anymore for using LS's API header files
107     - fixed warnings in API doc generation
108 schoenebeck 1065
109 schoenebeck 947 * general changes:
110     - replaced the old, confusing MIDI program change mechanism by a
111     flexible MIDI instrument mapper which allows to map arbitrary
112 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
113 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
114     loaded on the respective channel when such MIDI program change
115     messages arrive, beside that, each entry allows to define a life-time
116     strategy for the instrument, so the user can define whether the
117     instrument should i.e. be permanently loaded (to be able to switch
118     quickly among sounds) or i.e. loaded just on demand when the
119     respective program change arrives (to safe RAM space), as well as a
120     global volume factor for each entry, so the user can adjust the volume
121     dynamic of his mapped instrument collection without having to modify
122 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
123     MIDI instrument maps and assign each sampler channel individually
124     a certain map, so that i.e. separation of normal instruments and
125     drumkits is possible
126 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
127     MIDI instrument maps, MIDI instruments, FX sends, global volume.
128 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
129     due to a constant size RingBuffer FIFO which is now replaced by a
130     dynamic (unlimited) size std::list FIFO
131 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
132     output channels for being processed by external effect processors
133     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
134     controllers
135 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
136 iliev 1130 - Implemented new, improved notification system
137 schoenebeck 1149 - fixed compilation errors regarding OSX
138     (patch by Toshi Nagata)
139 iliev 1161 - implemented instruments database
140 iliev 1345 - added support for escape sequences to the instruments database
141 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
142     within the sampler's process (by using instrument editor plugins),
143     you'll notice the new "Registered instrument editors:" message on
144 schoenebeck 1407 startup, added a new LSCP command:
145     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
146 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
147     given sampler channel, the plugin path can be overridden at compile
148     time with ./configure --enable-plugin-dir=/some/dir
149 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
150     in the sampler's process to safely edit instruments while playing
151     without a crash (hopefully) by either suspending single regions
152     wherever possible or if unavoidable whole engine(s)
153 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
154     policy and priority on thread level, set a minimum stack size for
155     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
156     threads simply inherited properties of starting thread instead of
157     setting their own policy and priority
158 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
159     main process did not wait for the stack trace process to finish
160     its output
161 persson 1248 - fixed some minor memory leaks
162 schoenebeck 1259 - reenabled assembly features support, at the moment only for
163     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
164 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
165     register, to avoid relocations in the text segment at runtime)
166 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
167 schoenebeck 947
168     * MIDI driver:
169     - dispatch bank select (MSB and LSB) messages
170    
171 schoenebeck 1049 * audio driver:
172     - the ALSA audio output driver parameters now reflect the correct
173     parameter value ranges for the respective selected sound card
174     (patch by Till Wimmer, a bit fixed and extended)
175    
176 persson 951 * Gigasampler format engine:
177     - if a filter is used and EG2 finishes before EG1, let the voice
178     die when EG2 has finished (this fixes a problem with clicks and
179     voice starvation for some gigs)
180 persson 1038 - playback is no longer disabled during instrument loading
181     - all notes playing on a channel that changes its instrument keep
182     playing with the old instrument until they get a note off
183     command
184 persson 1039 - EG fix: a release value of zero could cause noises or crash
185 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
186 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
187     above max sustain level, which means that there is a decay phase
188     even if sustain is 100%
189 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
190     noises or crashes
191 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
192 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
193     supplied to the configure script (fixes #46)
194 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
195     instead of a fix value
196 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
197     127 (solo mode) only kill voices if the respective mode really
198     changed
199 persson 951
200 schoenebeck 1244 * LSCP server:
201     - fixed compile time error for old Bison versions
202     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
203 schoenebeck 1245 - parser now supports extended ASCII character set
204     (up to ASCII code 255, i.e. includes now umlauts and accents)
205     - filename arguments in LSCP commands now allow to use escape
206     sequences, that is directly literal as one of: \', \", \\, \n, \r,
207     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
208     code value like \xf2) (fixes bug #24)
209 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
210     least one of their text-based parameters (i.e. name, description):
211     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
212     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
213     "SET DB_INSTRUMENT_DIRECTORY NAME",
214     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
215     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
216     "FIND DB_INSTRUMENT_DIRECTORIES"
217 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
218     occured, the unexpected character and the actually expected, possible
219     character(s), the latter only if less than 5 possibilities)
220 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
221     settings
222 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
223     of strings were treated as being one string containing commas
224     (fixes #57)
225 schoenebeck 1244
226 iliev 959 * Bug fixes:
227     - fixed crash occurring on certain LSCP scripts (Bug 39)
228 persson 1038 - another thread safety fix for lscp "load engine" and "set
229     channel audio output device"
230 iliev 1283 - fixed a crash which occurs when reassigning the same engine
231     on a sampler channel with connected MIDI device
232 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
233     device connected to a sampler channel to number less then or equal
234     to the index of the port to which the sampler channel is connected.
235 iliev 1296 - The previous bindings were not been disconnected when altering
236     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
237     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
238 iliev 1297 - The active stream/voice count statistic was incorrect.
239 iliev 1298 - notification events were not been sent for some sampler
240     channel changes
241 iliev 1305 - added default min and max values to restrict the number of allowed
242     audio output channels and MIDI input ports
243 iliev 1306 - the connection to the PCM interface is now closed when destroying
244     an audio output device
245 schoenebeck 1332 - files with slash in their path or filename could not be loaded
246 iliev 959
247 schoenebeck 1221 * test cases:
248     - updated and fixed (haven't been touched in a while)
249    
250 schoenebeck 937 Version 0.4.0 (24 November 2006)
251 persson 696
252 schoenebeck 697 * packaging changes:
253 capela 868 - changed deprecated copyright attribute to license; added ldconfig
254     to post-(un)install steps; added devel package for liblinuxsampler;
255     to linuxsampler.spec (RPM)
256 schoenebeck 697 - install necessary development header files for allowing 3rd party
257     applications to link against liblinuxsampler
258     - liblinuxsampler's API documentation can be generated with 'make docs'
259     (Doxygen required)
260 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
261     implementation (currently either an integer math solution or a
262     di-harmonic approximation), automatic detection can be overriden
263     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
264     configure script argument though (mandatory for cross-compilation)
265 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
266     provided some on his own (as CXXFLAGS)
267 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
268     messages
269 schoenebeck 852 - added compile time options to allow disabling the various audio and
270     MIDI drivers
271 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
272     (patch by Ebrahim Mayat)
273 schoenebeck 697
274 persson 696 * Gigasampler format engine:
275 schoenebeck 738 - extensive synthesis optimization
276     (reimplementation of EGs and LFO(s), removed synthesis parameter
277     prerendering and the synthesis parameter matrix in general, splitting
278     each audio fragment into subfragments now where each subfragment uses
279 persson 830 constant pitch and filter coefficients. The volume coefficient is
280     linearly interpolated inside a subfragment, unless
281     --disable-interpolate-volume is set.)
282 persson 696 - fine tuning of the EG modulation parameters
283 persson 729 - improved filter cutoff calculation by adding support for the
284     following gig parameters: Cutoff freq (used when no cutoff
285     controller is defined), Control invert, Minimum cutoff, Velocity
286 persson 791 curve and Velocity range. The keyboard tracking now scales
287     cutoff frequency instead of resonance.
288 persson 877 - added support for gig parameter Resonance.
289 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
290 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
291     which can be overridden with --enable-global-attenuation
292 persson 783 - EG fixes: made the length of "attack hold" stage more
293     accurate. Release stage can now start before attack stage
294 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
295     time now has a minimal value to prevent clicks.
296 persson 799 - fixed pitch changes larger than one octave
297 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
298     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
299     all modes can be altered via standard GM messages, that is CC5 for
300     altering portamento time, CC65 for enabling / disabling portamento
301     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
302 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
303     parameter) and crossfade
304 persson 831 - added support for the "attenuation controller threshold" gig
305     parameter
306 persson 832 - added smoothing of volume changes caused by control change
307     messages
308 persson 865 - sample loop parameters are now taken from the DimensionRegion
309     instead of the wave chunk
310     - fixed keyswitching for v3 gigs with a number of keyswitch splits
311     not equal to a power of two
312 persson 877 - reimplementation of the filter algorithm. The new filter is more
313     accurate and supports all gig filter types, including bandreject
314     and lowpass turbo.
315 persson 903 - real support for 24 bit samples - samples are not truncated to
316     16 bits anymore
317     - support for aftertouch (channel pressure, not polyphonic
318     aftertouch)
319 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
320     amplifying from 0)
321 persson 696
322 schoenebeck 711 * LSCP server:
323     - fixed application exit on broken pipe error (fixes bug #20)
324 iliev 793 - fixed the notification messages delay due to lack of
325     network activity (fixes bug #26)
326 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
327     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
328 schoenebeck 711
329 schoenebeck 838 * audio driver:
330     - added aRts audio output driver (by no means RT safe)
331    
332 schoenebeck 775 * MIDI driver:
333     - fixed legacy sysex code which caused dispatching of MIDI SysEx
334     messages several times instead of once
335 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
336     for events (i.e. for offline rendering based MIDI drivers)
337 persson 922 - added checks for bad MIDI data
338 schoenebeck 775
339 schoenebeck 900 * linuxsampler application:
340     - show available sampler engine types on startup
341    
342 schoenebeck 705 * general changes:
343     - support for muting sampler channels and solo mode of the same, two new
344     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
345     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
346     introduced for this, the behavior is the same like on a mixer console
347 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
348     --enable-process-muted-channels which can be used to enable the
349     processing of muted channels.
350 iliev 777 - support for sostenuto pedal
351 iliev 779 - support for monitoring the total number of active voices
352 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
353     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
354 persson 835 - fixed some memory management errors
355 persson 841 - fixed some concurrency problems that could lead to crashes when
356     LSCP commands were executed
357 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
358     sampler channel (fixes bug #36)
359 schoenebeck 705
360 schoenebeck 692 Version 0.3.3 (15 July 2005)
361 schoenebeck 686
362     * packaging changes:
363     - fixed compilation with gcc 4.0
364    
365 schoenebeck 687 * Gigasampler format engine:
366     - LFO preprocessing was performed even though the respective LFO was
367     disabled by the instrument patch (minor efficiency fix)
368 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
369     for volume ramp downs in the same fragment (needed for current voice
370     stealing implementation) then simply inform the user with a warning
371     about possible click sounds and reduce the volume ramp down
372     appropriately instead of cancelling the audio device connection
373 schoenebeck 687
374 schoenebeck 677 Version 0.3.2 (24 June 2005)
375 schoenebeck 609
376     * packaging changes:
377     - updated autotools build files to compile on OS X
378     (conditional compilation of CoreMIDI and MidiShare drivers)
379 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
380     './configure --disable-asm' (definitely not recommended)
381 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
382     - require automake (>= 1.5) for 'make -f Makefile.cvs'
383     (due to 'dist-bzip2' automake option)
384 schoenebeck 649
385     * Gigasampler format engine:
386     - support for the gig parameters for "release velocity response" curves
387     - fine tuning of the EGADSR envelope
388     - volume of release triggered samples now depends on note-on velocity,
389     note length and gig parameter "release trigger decay" instead of
390     note-off velocity.
391 schoenebeck 663 - revised voice stealing
392     (fixes crash and endless loop caused by voice stealing)
393 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
394 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
395     instead of when the respective voice is actually launched
396     (fixes undefined behavior if stolen voices belonged to a key group -
397     this case was followed by a "killed voice survived" error message)
398 schoenebeck 669 - fixed minor issue with null/silence samples
