* fixed crash on x86_64, introduced in 2008-11-02 commit (#108)
* fixed configure so it detects x86_64 (#107)

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