File size: 25335 byte(s)
* fixed CPU feature detection on x86_64 (maybe fixes #108)

1 Version CVS HEAD (?)
2
3 * 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 - fixed compilation with gcc 4.3
9 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
10 - fixed configure so it detects x86_64 (#107)
11 - fixes for building with newer MinGW versions
12 - fix for building with bison 2.4 (#111)
13
14 * general changes:
15 - bugfix: on some POSIX systems instrument editor plugins refused to
16 load as we used a non-portable Linux specific struct field
17 (fixes bug #70, patch by Ronald Baljeu)
18 - fixed endless loop which occured when loading an instrument editor
19 plugin DLL on Windows systems failed
20 - fixed memory leaks that occurred when liblinuxsampler was unloaded
21 - optimized the SynchronizedConfig class so it doesn't wait
22 unnecessarily long after an update
23 - added support for notifying instrument editors on note-on / note-off
24 events (e.g. to highlight the pressed keys on the virtual keyboard
25 of gigedit)
26 - added support for triggering notes by instrument editors (see above)
27 - be verbose on DLL load errors (on Linux)
28 - fixed di-harmonic triangle LFO implementation (this LFO implementation
29 is only used by very few systems, most pick the int math
30 implementation, which is usually faster)
31 - fixes for audio drivers with varying buffer sizes
32 - experimental support for running LinuxSampler as a DSSI, LV2 and
33 VST plugin
34 - notification events for stream/voice count statistics are now sent
35 only when there are actual changes
36 - added memory ordering constraints to improve stability on
37 multi-core and multi-cpu systems
38 - maximum voices and disk streams can now be altered at runtime
39 - fixed CPU feature detection on x86_64 (maybe fixes #108)
40
41 * audio driver:
42 - removed the nonsense audio channel constraint (which was hard coded to
43 max. 100 audio channels) for most audio drivers
44 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
45 opposed to the LSCP specs
46 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
47 reflected the wrong value
48 - fixed a memory management bug in ASIO driver
49 - Makefile fix: JACK_CFLAGS wasn't used
50 - JACK: use jack_client_open instead of the deprecated
51 jack_client_new
52
53 * MIDI driver:
54 - added JACK MIDI driver
55 - dispatch bank select as ordinary CC as well, the user might seriously
56 want to (mis)use it for some purpose ("fixed" in all current MIDI
57 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
58
59 * instruments database:
60 - avoid time consuming samples scanning when adding instruments
61 to the instruments database
62 - added support for handling lost files in the instruments database
63 - Implemented option for adding instruments in separate directories
64 in the instruments database
65 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
66
67 * Gigasampler format engine:
68 - fixed a memory leak that could happen when a channel was deleted
69 while notes were playing
70 - made it possible to load an instrument even if the audio thread
71 isn't running
72 - added partial support for the "Controller Triggered" MIDI rule,
73 enough for piano gigs with pedal noise samples
74 - minor fix: only mark FX sends as being modified if really the
75 respective FX send MIDI controller was used
76 - added support for GM global device volume SysEx message
77 (can be selected at compile time to either apply globally to the
78 whole sampler [default] or only to the sampler channels that are
79 connected to the respective MIDI input port the SysEx message arrived
80 on)
81 - bugfix: notes triggered at position 0 in the audio buffer were
82 sometimes wrongly killed in the same buffer, causing no sound to
83 be played
84 - added support for chromatic / drumkit mode Roland GS Sysex message
85 which is usally used to switch a part between chromatic sounds and
86 drumkit sounds (as opposed to their common default setting of MIDI
87 part 10 being a drumkit part and all other ones chromatic parts), in
88 LS however one can switch between the first 16 MIDI instrument maps
89 defined for the sampler
90 - made it possible to create multiple sample channels even if the
91 audio thread isn't running
92
93 * LSCP server:
94 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
95 react on MIDI data arriving on certain sampler channels (so far only
96 Note-On and Note-Off events are sent via this LSCP event)
97 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
98 react on MIDI data arriving on certain MIDI input devices (so far only
99 Note-On and Note-Off events are sent via this LSCP event)
100 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
101 SET DB_INSTRUMENT FILE_PATH
102 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
103 frontends to send MIDI messages to specific sampler channel
104 - added two additional fields to GET FILE INSTRUMENT INFO command -
105 KEY_BINDINGS and KEYSWITCH_BINDINGS
106 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
107 was incorrect
108 - Optimized the retrieval of the MIDI instrument mappings
109 - added new LSCP command "SET VOICES" to globally alter the maximum
110 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
111 be triggered respectively
112 - added new LSCP command "SET STREAMS" to globally alter the maximum
113 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
114 which will be triggered respectively
115 - bugfix: retry if "select" returns EINTR (this fixes a crash when
116 a gigedit file dialog is opened)
117
118 * Bug fixes:
119 - fixed a crash which occurs when removing a sampler channel waiting
120 to start instrument loading after another channel
121
122
123 Version 0.5.1 (6 December 2007)
124
125 * packaging changes:
126 - added autoconf checks for pthread library
127 - added autoconf check for pthread bug found on certain NPTL-enabled
128 glibc versions (see Gentoo bug report #194076)
129 - added autoconf checks for MS Windows
130
131 * general changes:
132 - bugfix: the thread used by an editor plugin didn't die when the
133 editor closed
134 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
135 out all the space. operator--() did not apply size_mask after
136 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
137 order to avoid problems with the _NonVolatileReader functions.
138 - bugfix: Stream.h: added a missing divide by BytesPerSample in
139 GetWriteSpace(). Since this function is currently only used in
140 the stream's qsort() compare function, it didn't trigger any
141 bugs.
142 - Resampler.h, Synthesizer.h: cubic interpolation now works in
143 24bit mode too. Faster method to read 24bit words on little
144 endian machines (x86): replaced 3 byte reads + shifts with a 1
145 unaligned 32bit read and shift
146 - experimental support for MS Windows (MIDI input via MME, AUDIO
147 output via ASIO)
148 - made handling of SIGINT signal (Ctrl-C) a bit more robust
149 - support for monitoring the total number of active disk streams
150 (new LSCP commands: GET TOTAL_STREAM_COUNT,
151 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
152
153 * AUDIO driver:
154 - added Windows ASIO low latency audio driver
155
156 * MIDI driver:
157 - added MME Windows MIDI driver
158
159 * LSCP server:
160 - added support for Windows style path / filenames, however with
161 forward slash path separators instead of backslash
162 (i.e. "C:/foo/bar.gig")
163 - allow naughty liblscp to send non-string device parameters within
164 apostrophes as well
165 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
166 "LIST FILE INSTRUMENTS <file>" and
167 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
168 about an arbitrary instrument file on the system where the sampler is
169 running on
170
171 Version 0.5.0 (15 October 2007)
172
173 * packaging changes:
174 - config.h is not going to be installed along with liblinuxsampler's
175 API header files anymore
176 - only the API relevant header (and source) files will be exported to
177 the Doxygen API documentation (explicitly listed in Doxyfile.in)
178 - added completely new XCode project files for Mac OSX which is now
179 capable to execute our autoconf environment, thus no need anymore
180 to maintain the compile time configuration file (osx/version.h) for
181 OSX manually (patch by Toshi Nagata)
182 - fixed buggy boolean --enable-foo / --disable-foo configure script
183 parameters
184 - global.h now only covers global definitions that are needed for the
185 C++ API header files, all implementation internal global definitions
186 are now in global_private.h
187 - atomic.h is not exposed to the C++ API anymore
188 - no need to include config.h anymore for using LS's API header files
189 - fixed warnings in API doc generation
190
191 * general changes:
192 - replaced the old, confusing MIDI program change mechanism by a
193 flexible MIDI instrument mapper which allows to map arbitrary
194 (MIDI bank, MIDI program) pairs with arbitrary
195 (engine type, instrument file, file index) triplets which will be
196 loaded on the respective channel when such MIDI program change
197 messages arrive, beside that, each entry allows to define a life-time
198 strategy for the instrument, so the user can define whether the
199 instrument should i.e. be permanently loaded (to be able to switch
200 quickly among sounds) or i.e. loaded just on demand when the
201 respective program change arrives (to safe RAM space), as well as a
202 global volume factor for each entry, so the user can adjust the volume
203 dynamic of his mapped instrument collection without having to modify
204 the instrument files, also one can manage arbitrary amount of such
205 MIDI instrument maps and assign each sampler channel individually
206 a certain map, so that i.e. separation of normal instruments and
207 drumkits is possible
208 - new notification events for tracking changes to audio/MIDI devices,
209 MIDI instrument maps, MIDI instruments, FX sends, global volume.
210 - sampler was limited to load max. 200 instruments in the background
211 due to a constant size RingBuffer FIFO which is now replaced by a
212 dynamic (unlimited) size std::list FIFO
213 - added FX sends, these allow to route audio signals to arbitrary audio
214 output channels for being processed by external effect processors
215 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
216 controllers
217 - global (sampler wide) volume can now be controlled at runtime
218 - Implemented new, improved notification system
219 - fixed compilation errors regarding OSX
220 (patch by Toshi Nagata)
221 - implemented instruments database
222 - added support for escape sequences to the instruments database
223 - added highly experimental support for on-the-fly instrument editing
224 within the sampler's process (by using instrument editor plugins),
225 you'll notice the new "Registered instrument editors:" message on
226 startup, added a new LSCP command:
227 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
228 to spawn a matching instrument editor for the instrument on the
229 given sampler channel, the plugin path can be overridden at compile
230 time with ./configure --enable-plugin-dir=/some/dir
231 - added experimental code for synchronizing instrument editors hosted
232 in the sampler's process to safely edit instruments while playing
233 without a crash (hopefully) by either suspending single regions
234 wherever possible or if unavoidable whole engine(s)
235 - fixed several issues in fundamental "Thread" class: set scheduling
236 policy and priority on thread level, set a minimum stack size for
237 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
238 threads simply inherited properties of starting thread instead of
239 setting their own policy and priority
240 - minor fix in our automatic stack trace mechanism on crashes, the
241 main process did not wait for the stack trace process to finish
242 its output
243 - fixed some minor memory leaks
244 - reenabled assembly features support, at the moment only for
245 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
246 - minor assembly fix in x86 features detection (don't use the PIC
247 register, to avoid relocations in the text segment at runtime)
248 - POSIX callback functions of Thread.h are hidden
249
250 * MIDI driver:
251 - dispatch bank select (MSB and LSB) messages
252
253 * audio driver:
254 - the ALSA audio output driver parameters now reflect the correct
255 parameter value ranges for the respective selected sound card
256 (patch by Till Wimmer, a bit fixed and extended)
257
258 * Gigasampler format engine:
259 - if a filter is used and EG2 finishes before EG1, let the voice
260 die when EG2 has finished (this fixes a problem with clicks and
261 voice starvation for some gigs)
262 - playback is no longer disabled during instrument loading
263 - all notes playing on a channel that changes its instrument keep
264 playing with the old instrument until they get a note off
265 command
266 - EG fix: a release value of zero could cause noises or crash
267 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
268 - EG fine tuning: when attack is zero the EG starts at a level
269 above max sustain level, which means that there is a decay phase
270 even if sustain is 100%
271 - more EG fixes: the level could sometimes go below zero and cause
272 noises or crashes
273 - minor fix of EGDecay (patch by Toshi Nagata)
274 - fixed compiler error when --enable-override-filter-type was
275 supplied to the configure script (fixes #46)
276 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
277 instead of a fix value
278 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
279 127 (solo mode) only kill voices if the respective mode really
280 changed
281
282 * LSCP server:
283 - fixed compile time error for old Bison versions
284 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
285 - parser now supports extended ASCII character set
286 (up to ASCII code 255, i.e. includes now umlauts and accents)
287 - filename arguments in LSCP commands now allow to use escape
288 sequences, that is directly literal as one of: \', \", \\, \n, \r,
289 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
290 code value like \xf2) (fixes bug #24)
291 - the following LSCP commands now also support escape sequences for at
292 least one of their text-based parameters (i.e. name, description):
293 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
294 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
295 "SET DB_INSTRUMENT_DIRECTORY NAME",
296 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
297 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
298 "FIND DB_INSTRUMENT_DIRECTORIES"
299 - returns verbose syntax errors (line and column where syntax error
300 occured, the unexpected character and the actually expected, possible
301 character(s), the latter only if less than 5 possibilities)
302 - made sure that LSCP syntax is not affected by gigedit locale
303 settings
304 - bugfix regarding strings parameter lists: all comma separated lists
305 of strings were treated as being one string containing commas
306 (fixes #57)
307
308 * Bug fixes:
309 - fixed crash occurring on certain LSCP scripts (Bug 39)
310 - another thread safety fix for lscp "load engine" and "set
311 channel audio output device"
312 - fixed a crash which occurs when reassigning the same engine
313 on a sampler channel with connected MIDI device
314 - fixed a crash which occurs when changing the number of ports of a MIDI
315 device connected to a sampler channel to number less then or equal
316 to the index of the port to which the sampler channel is connected.
317 - The previous bindings were not been disconnected when altering
318 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
319 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
320 - The active stream/voice count statistic was incorrect.
321 - notification events were not been sent for some sampler
322 channel changes
323 - added default min and max values to restrict the number of allowed
324 audio output channels and MIDI input ports
325 - the connection to the PCM interface is now closed when destroying
326 an audio output device
327 - files with slash in their path or filename could not be loaded
328
329 * test cases:
330 - updated and fixed (haven't been touched in a while)
331
332 Version 0.4.0 (24 November 2006)
333
334 * packaging changes:
335 - changed deprecated copyright attribute to license; added ldconfig
336 to post-(un)install steps; added devel package for liblinuxsampler;
337 to linuxsampler.spec (RPM)
338 - install necessary development header files for allowing 3rd party
339 applications to link against liblinuxsampler
340 - liblinuxsampler's API documentation can be generated with 'make docs'
341 (Doxygen required)
342 - added benchmark to automatically detect the best triangle LFO
343 implementation (currently either an integer math solution or a
344 di-harmonic approximation), automatic detection can be overriden
345 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
346 configure script argument though (mandatory for cross-compilation)
347 - do not automatically pick optimized gcc flags if the user already
348 provided some on his own (as CXXFLAGS)
349 - added compile time option to disable processing of All-Notes-Off MIDI
350 messages
351 - added compile time options to allow disabling the various audio and
352 MIDI drivers
353 - fixed automatic GCC CPU switch detection on PPC
354 (patch by Ebrahim Mayat)
355
356 * Gigasampler format engine:
357 - extensive synthesis optimization
358 (reimplementation of EGs and LFO(s), removed synthesis parameter
359 prerendering and the synthesis parameter matrix in general, splitting
360 each audio fragment into subfragments now where each subfragment uses
361 constant pitch and filter coefficients. The volume coefficient is
362 linearly interpolated inside a subfragment, unless
363 --disable-interpolate-volume is set.)
364 - fine tuning of the EG modulation parameters
365 - improved filter cutoff calculation by adding support for the
366 following gig parameters: Cutoff freq (used when no cutoff
367 controller is defined), Control invert, Minimum cutoff, Velocity
368 curve and Velocity range. The keyboard tracking now scales
369 cutoff frequency instead of resonance.
370 - added support for gig parameter Resonance.
371 - fixed bug in sysex handling (patch by Juan Linietsky)
372 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
373 which can be overridden with --enable-global-attenuation
374 - EG fixes: made the length of "attack hold" stage more
375 accurate. Release stage can now start before attack stage
376 ends. Cancel release didn't work when sustain was zero. Attack
377 time now has a minimal value to prevent clicks.
378 - fixed pitch changes larger than one octave
379 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
380 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
381 all modes can be altered via standard GM messages, that is CC5 for
382 altering portamento time, CC65 for enabling / disabling portamento
383 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
384 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
385 parameter) and crossfade
386 - added support for the "attenuation controller threshold" gig
387 parameter
388 - added smoothing of volume changes caused by control change
389 messages
390 - sample loop parameters are now taken from the DimensionRegion
391 instead of the wave chunk
392 - fixed keyswitching for v3 gigs with a number of keyswitch splits
393 not equal to a power of two
394 - reimplementation of the filter algorithm. The new filter is more
395 accurate and supports all gig filter types, including bandreject
396 and lowpass turbo.
397 - real support for 24 bit samples - samples are not truncated to
398 16 bits anymore
399 - support for aftertouch (channel pressure, not polyphonic
400 aftertouch)
401 - LFO1 behaviour fixed (dampening from max volume instead of
402 amplifying from 0)
403
404 * LSCP server:
405 - fixed application exit on broken pipe error (fixes bug #20)
406 - fixed the notification messages delay due to lack of
407 network activity (fixes bug #26)
408 - fixed parser bug which occured on space(s) within device parameters
409 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
410
411 * audio driver:
412 - added aRts audio output driver (by no means RT safe)
413
414 * MIDI driver:
415 - fixed legacy sysex code which caused dispatching of MIDI SysEx
416 messages several times instead of once
417 - API extension for MIDI drivers which already supply exact time stamps
418 for events (i.e. for offline rendering based MIDI drivers)
419 - added checks for bad MIDI data
420
421 * linuxsampler application:
422 - show available sampler engine types on startup
423
424 * general changes:
425 - support for muting sampler channels and solo mode of the same, two new
426 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
427 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
428 introduced for this, the behavior is the same like on a mixer console
429 (patch by Grigor Iliev, a bit adjusted). Also added configure option
430 --enable-process-muted-channels which can be used to enable the
431 processing of muted channels.
432 - support for sostenuto pedal
433 - support for monitoring the total number of active voices
434 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
435 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
436 - fixed some memory management errors
437 - fixed some concurrency problems that could lead to crashes when
438 LSCP commands were executed
439 - fixed crash when instrument loading failed previously on the same
440 sampler channel (fixes bug #36)
441
442 Version 0.3.3 (15 July 2005)
443
444 * packaging changes:
445 - fixed compilation with gcc 4.0
446
447 * Gigasampler format engine:
448 - LFO preprocessing was performed even though the respective LFO was
449 disabled by the instrument patch (minor efficiency fix)
450 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
451 for volume ramp downs in the same fragment (needed for current voice
452 stealing implementation) then simply inform the user with a warning
453 about possible click sounds and reduce the volume ramp down
454 appropriately instead of cancelling the audio device connection
455
456 Version 0.3.2 (24 June 2005)
457
458 * packaging changes:
459 - updated autotools build files to compile on OS X
460 (conditional compilation of CoreMIDI and MidiShare drivers)
461 - hand-crafted assembly optimization code can be disabled with
462 './configure --disable-asm' (definitely not recommended)
463 - fixed 'make dist' rule to include all necessary files
464 - require automake (>= 1.5) for 'make -f Makefile.cvs'
465 (due to 'dist-bzip2' automake option)
466
467 * Gigasampler format engine:
468 - support for the gig parameters for "release velocity response" curves
469 - fine tuning of the EGADSR envelope
470 - volume of release triggered samples now depends on note-on velocity,
471 note length and gig parameter "release trigger decay" instead of
472 note-off velocity.
473 - revised voice stealing
474 (fixes crash and endless loop caused by voice stealing)
475 - don't reset scale tuning on instrument or audio output device change
476 - handle key group conflicts right at the beginning of each fragment
477 instead of when the respective voice is actually launched
478 (fixes undefined behavior if stolen voices belonged to a key group -
479 this case was followed by a "killed voice survived" error message)
480 - fixed minor issue with null/silence samples
481 (those stole voices even though they don't need a voice at all which
482 resulted in "voice stealing didn't work out" messages)
483 - don't reset volume, pan, pitch and MIDI controller values on
484 instrument or audio output device change
485
486 * LSCP server:
487 - fixed some crashes (patch by Grigor Iliev, fixes #19)
488 - fixed LSCP event "CHANNEL_INFO" notification
489 (e.g. did not notify on volume changes or MIDI program change events)
490
491 * linuxsampler application:
492 - added command line parameters --lscp-addr and --lscp-port to override
493 default IP address and port of LSCP server
494
495 Version 0.3.1 (24 May 2005)
496
497 * initial release
