File size: 23139 byte(s)
* added support for chromatic / drumkit mode Roland GS Sysex message
  which is usally used to switch a part between chromatic sounds and
  drumkit sounds (as opposed to their common default setting of MIDI
  part 10 being a drumkit part and all other ones chromatic parts), in
  LS however one can switch between the first 16 MIDI instrument maps
  of all ones defined for the sampler
* bumped version to 0.5.1.6cvs

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