- added partial support for the "Controller Triggered" MIDI rule,
  enough for piano gigs with pedal noise samples

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 1653 - added support for notifying instrument editors on note-on / note-off
19     events (e.g. to highlight the pressed keys on the virtual keyboard
20     of gigedit)
21 schoenebeck 1659 - added support for triggering notes by instrument editors (see above)
22 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
23 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation
24     is only used by very few systems, most pick the int math
25     implementation, which is usually faster)
26 schoenebeck 1601
27 schoenebeck 1599 * audio driver:
28     - removed the nonsense audio channel constraint (which was hard coded to
29     max. 100 audio channels) for most audio drivers
30 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
31     opposed to the LSCP specs
32 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
33     reflected the wrong value
34 persson 1644 - fixed a memory management bug in ASIO driver
35 schoenebeck 1599
36 persson 1651 * MIDI driver:
37     - added JACK MIDI driver
38    
39 schoenebeck 1604 * instruments database:
40 iliev 1603 - avoid time consuming samples scanning when adding instruments
41     to the instruments database
42    
43 persson 1644 * Gigasampler format engine:
44     - fixed a memory leak that could happen when a channel was deleted
45     while notes were playing
46 persson 1646 - made it possible to load an instrument even if the audio thread
47     isn't running
48 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
49     enough for piano gigs with pedal noise samples
50 persson 1644
51 schoenebeck 1687 * LSCP server:
52     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
53     react on MIDI data arriving on certain sampler channels (so far only
54     Note-On and Note-Off events are sent via this LSCP event)
55 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
56     react on MIDI data arriving on certain MIDI input devices (so far only
57     Note-On and Note-Off events are sent via this LSCP event)
58 schoenebeck 1687
59 schoenebeck 1560 Version 0.5.1 (6 December 2007)
60 schoenebeck 1454
61     * packaging changes:
62     - added autoconf checks for pthread library
63     - added autoconf check for pthread bug found on certain NPTL-enabled
64     glibc versions (see Gentoo bug report #194076)
65 senoner 1502 - added autoconf checks for MS Windows
66 schoenebeck 1454
67 persson 1455 * general changes:
68     - bugfix: the thread used by an editor plugin didn't die when the
69     editor closed
70 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
71     out all the space. operator--() did not apply size_mask after
72     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
73     order to avoid problems with the _NonVolatileReader functions.
74     - bugfix: Stream.h: added a missing divide by BytesPerSample in
75     GetWriteSpace(). Since this function is currently only used in
76     the stream's qsort() compare function, it didn't trigger any
77     bugs.
78     - Resampler.h, Synthesizer.h: cubic interpolation now works in
79     24bit mode too. Faster method to read 24bit words on little
80     endian machines (x86): replaced 3 byte reads + shifts with a 1
81     unaligned 32bit read and shift
82     - experimental support for MS Windows (MIDI input via MME, AUDIO
83     output via ASIO)
84     - made handling of SIGINT signal (Ctrl-C) a bit more robust
85 iliev 1541 - support for monitoring the total number of active disk streams
86     (new LSCP commands: GET TOTAL_STREAM_COUNT,
87     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
88 persson 1455
89 senoner 1500 * AUDIO driver:
90 persson 1534 - added Windows ASIO low latency audio driver
91 senoner 1500
92 senoner 1485 * MIDI driver:
93 schoenebeck 1495 - added MME Windows MIDI driver
94 senoner 1485
95 schoenebeck 1471 * LSCP server:
96     - added support for Windows style path / filenames, however with
97     forward slash path separators instead of backslash
98     (i.e. "C:/foo/bar.gig")
99 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
100     apostrophes as well
101 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
102     "LIST FILE INSTRUMENTS <file>" and
103     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
104     about an arbitrary instrument file on the system where the sampler is
105     running on
106 schoenebeck 1471
107 schoenebeck 1424 Version 0.5.0 (15 October 2007)
108 schoenebeck 947
109 schoenebeck 1065 * packaging changes:
110 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
111     API header files anymore
112 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
113     the Doxygen API documentation (explicitly listed in Doxyfile.in)
114 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
115     capable to execute our autoconf environment, thus no need anymore
116     to maintain the compile time configuration file (osx/version.h) for
117     OSX manually (patch by Toshi Nagata)
118 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
119     parameters
120 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
121     C++ API header files, all implementation internal global definitions
122     are now in global_private.h
123     - atomic.h is not exposed to the C++ API anymore
124     - no need to include config.h anymore for using LS's API header files
125     - fixed warnings in API doc generation
126 schoenebeck 1065
127 schoenebeck 947 * general changes:
128     - replaced the old, confusing MIDI program change mechanism by a
129     flexible MIDI instrument mapper which allows to map arbitrary
130 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
131 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
132     loaded on the respective channel when such MIDI program change
133     messages arrive, beside that, each entry allows to define a life-time
134     strategy for the instrument, so the user can define whether the
135     instrument should i.e. be permanently loaded (to be able to switch
136     quickly among sounds) or i.e. loaded just on demand when the
137     respective program change arrives (to safe RAM space), as well as a
138     global volume factor for each entry, so the user can adjust the volume
139     dynamic of his mapped instrument collection without having to modify
140 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
141     MIDI instrument maps and assign each sampler channel individually
142     a certain map, so that i.e. separation of normal instruments and
143     drumkits is possible
144 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
145     MIDI instrument maps, MIDI instruments, FX sends, global volume.
146 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
147     due to a constant size RingBuffer FIFO which is now replaced by a
148     dynamic (unlimited) size std::list FIFO
149 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
150     output channels for being processed by external effect processors
151     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
152     controllers
153 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
154 iliev 1130 - Implemented new, improved notification system
155 schoenebeck 1149 - fixed compilation errors regarding OSX
156     (patch by Toshi Nagata)
157 iliev 1161 - implemented instruments database
158 iliev 1345 - added support for escape sequences to the instruments database
159 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
160     within the sampler's process (by using instrument editor plugins),
161     you'll notice the new "Registered instrument editors:" message on
162 schoenebeck 1407 startup, added a new LSCP command:
163     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
164 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
165     given sampler channel, the plugin path can be overridden at compile
166     time with ./configure --enable-plugin-dir=/some/dir
167 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
168     in the sampler's process to safely edit instruments while playing
169     without a crash (hopefully) by either suspending single regions
170     wherever possible or if unavoidable whole engine(s)
171 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
172     policy and priority on thread level, set a minimum stack size for
173     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
174     threads simply inherited properties of starting thread instead of
175     setting their own policy and priority
176 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
177     main process did not wait for the stack trace process to finish
178     its output
179 persson 1248 - fixed some minor memory leaks
180 schoenebeck 1259 - reenabled assembly features support, at the moment only for
181     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
182 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
183     register, to avoid relocations in the text segment at runtime)
184 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
185 schoenebeck 947
186     * MIDI driver:
187     - dispatch bank select (MSB and LSB) messages
188    
189 schoenebeck 1049 * audio driver:
190     - the ALSA audio output driver parameters now reflect the correct
191     parameter value ranges for the respective selected sound card
192     (patch by Till Wimmer, a bit fixed and extended)
193    
194 persson 951 * Gigasampler format engine:
195     - if a filter is used and EG2 finishes before EG1, let the voice
196     die when EG2 has finished (this fixes a problem with clicks and
197     voice starvation for some gigs)
198 persson 1038 - playback is no longer disabled during instrument loading
199     - all notes playing on a channel that changes its instrument keep
200     playing with the old instrument until they get a note off
201     command
202 persson 1039 - EG fix: a release value of zero could cause noises or crash
203 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
204 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
205     above max sustain level, which means that there is a decay phase
206     even if sustain is 100%
207 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
208     noises or crashes
209 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
210 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
211     supplied to the configure script (fixes #46)
212 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
213     instead of a fix value
214 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
215     127 (solo mode) only kill voices if the respective mode really
216     changed
217 persson 951
218 schoenebeck 1244 * LSCP server:
219     - fixed compile time error for old Bison versions
220     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
221 schoenebeck 1245 - parser now supports extended ASCII character set
222     (up to ASCII code 255, i.e. includes now umlauts and accents)
223     - filename arguments in LSCP commands now allow to use escape
224     sequences, that is directly literal as one of: \', \", \\, \n, \r,
225     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
226     code value like \xf2) (fixes bug #24)
227 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
228     least one of their text-based parameters (i.e. name, description):
229     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
230     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
231     "SET DB_INSTRUMENT_DIRECTORY NAME",
232     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
233     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
234     "FIND DB_INSTRUMENT_DIRECTORIES"
235 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
236     occured, the unexpected character and the actually expected, possible
237     character(s), the latter only if less than 5 possibilities)
238 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
239     settings
240 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
241     of strings were treated as being one string containing commas
242     (fixes #57)
243 schoenebeck 1244
244 iliev 959 * Bug fixes:
245     - fixed crash occurring on certain LSCP scripts (Bug 39)
246 persson 1038 - another thread safety fix for lscp "load engine" and "set
247     channel audio output device"
248 iliev 1283 - fixed a crash which occurs when reassigning the same engine
249     on a sampler channel with connected MIDI device
250 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
251     device connected to a sampler channel to number less then or equal
252     to the index of the port to which the sampler channel is connected.
253 iliev 1296 - The previous bindings were not been disconnected when altering
254     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
255     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
256 iliev 1297 - The active stream/voice count statistic was incorrect.
257 iliev 1298 - notification events were not been sent for some sampler
258     channel changes
259 iliev 1305 - added default min and max values to restrict the number of allowed
260     audio output channels and MIDI input ports
261 iliev 1306 - the connection to the PCM interface is now closed when destroying
262     an audio output device
263 schoenebeck 1332 - files with slash in their path or filename could not be loaded
264 iliev 959
265 schoenebeck 1221 * test cases:
266     - updated and fixed (haven't been touched in a while)
267    
268 schoenebeck 937 Version 0.4.0 (24 November 2006)
269 persson 696
270 schoenebeck 697 * packaging changes:
271 capela 868 - changed deprecated copyright attribute to license; added ldconfig
272     to post-(un)install steps; added devel package for liblinuxsampler;
273     to linuxsampler.spec (RPM)
274 schoenebeck 697 - install necessary development header files for allowing 3rd party
275     applications to link against liblinuxsampler
276     - liblinuxsampler's API documentation can be generated with 'make docs'
277     (Doxygen required)
278 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
279     implementation (currently either an integer math solution or a
280     di-harmonic approximation), automatic detection can be overriden
281     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
282     configure script argument though (mandatory for cross-compilation)
283 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
284     provided some on his own (as CXXFLAGS)
285 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
286     messages
287 schoenebeck 852 - added compile time options to allow disabling the various audio and
288     MIDI drivers
289 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
290     (patch by Ebrahim Mayat)
291 schoenebeck 697
292 persson 696 * Gigasampler format engine:
293 schoenebeck 738 - extensive synthesis optimization
294     (reimplementation of EGs and LFO(s), removed synthesis parameter
295     prerendering and the synthesis parameter matrix in general, splitting
296     each audio fragment into subfragments now where each subfragment uses
297 persson 830 constant pitch and filter coefficients. The volume coefficient is
298     linearly interpolated inside a subfragment, unless
299     --disable-interpolate-volume is set.)
300 persson 696 - fine tuning of the EG modulation parameters
301 persson 729 - improved filter cutoff calculation by adding support for the
302     following gig parameters: Cutoff freq (used when no cutoff
303     controller is defined), Control invert, Minimum cutoff, Velocity
304 persson 791 curve and Velocity range. The keyboard tracking now scales
305     cutoff frequency instead of resonance.
306 persson 877 - added support for gig parameter Resonance.
307 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
308 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
309     which can be overridden with --enable-global-attenuation
310 persson 783 - EG fixes: made the length of "attack hold" stage more
311     accurate. Release stage can now start before attack stage
312 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
313     time now has a minimal value to prevent clicks.
314 persson 799 - fixed pitch changes larger than one octave
315 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
316     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
317     all modes can be altered via standard GM messages, that is CC5 for
318     altering portamento time, CC65 for enabling / disabling portamento
319     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
320 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
321     parameter) and crossfade
322 persson 831 - added support for the "attenuation controller threshold" gig
323     parameter
324 persson 832 - added smoothing of volume changes caused by control change
325     messages
326 persson 865 - sample loop parameters are now taken from the DimensionRegion
327     instead of the wave chunk
328     - fixed keyswitching for v3 gigs with a number of keyswitch splits
329     not equal to a power of two
330 persson 877 - reimplementation of the filter algorithm. The new filter is more
331     accurate and supports all gig filter types, including bandreject
332     and lowpass turbo.
333 persson 903 - real support for 24 bit samples - samples are not truncated to
334     16 bits anymore
335     - support for aftertouch (channel pressure, not polyphonic
336     aftertouch)
337 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
338     amplifying from 0)
339 persson 696
340 schoenebeck 711 * LSCP server:
341     - fixed application exit on broken pipe error (fixes bug #20)
342 iliev 793 - fixed the notification messages delay due to lack of
343     network activity (fixes bug #26)
344 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
345     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
346 schoenebeck 711
347 schoenebeck 838 * audio driver:
348     - added aRts audio output driver (by no means RT safe)
349    
350 schoenebeck 775 * MIDI driver:
351     - fixed legacy sysex code which caused dispatching of MIDI SysEx
352     messages several times instead of once
353 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
354     for events (i.e. for offline rendering based MIDI drivers)
355 persson 922 - added checks for bad MIDI data
356 schoenebeck 775
357 schoenebeck 900 * linuxsampler application:
358     - show available sampler engine types on startup
359    
360 schoenebeck 705 * general changes:
361     - support for muting sampler channels and solo mode of the same, two new
362     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
363     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
364     introduced for this, the behavior is the same like on a mixer console
365 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
366     --enable-process-muted-channels which can be used to enable the
367     processing of muted channels.
368 iliev 777 - support for sostenuto pedal
369 iliev 779 - support for monitoring the total number of active voices
370 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
371     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
372 persson 835 - fixed some memory management errors
373 persson 841 - fixed some concurrency problems that could lead to crashes when
374     LSCP commands were executed
375 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
376     sampler channel (fixes bug #36)
377 schoenebeck 705
378 schoenebeck 692 Version 0.3.3 (15 July 2005)
379 schoenebeck 686
380     * packaging changes:
381     - fixed compilation with gcc 4.0
382    
383 schoenebeck 687 * Gigasampler format engine:
384     - LFO preprocessing was performed even though the respective LFO was
385     disabled by the instrument patch (minor efficiency fix)
386 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
387     for volume ramp downs in the same fragment (needed for current voice
388     stealing implementation) then simply inform the user with a warning
389     about possible click sounds and reduce the volume ramp down
390     appropriately instead of cancelling the audio device connection
391 schoenebeck 687
392 schoenebeck 677 Version 0.3.2 (24 June 2005)
393 schoenebeck 609
394     * packaging changes:
395     - updated autotools build files to compile on OS X
396     (conditional compilation of CoreMIDI and MidiShare drivers)
397 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
398     './configure --disable-asm' (definitely not recommended)
399 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
400     - require automake (>= 1.5) for 'make -f Makefile.cvs'
401     (due to 'dist-bzip2' automake option)
402 schoenebeck 649
403     * Gigasampler format engine:
404     - support for the gig parameters for "release velocity response" curves
405     - fine tuning of the EGADSR envelope
406     - volume of release triggered samples now depends on note-on velocity,
407     note length and gig parameter "release trigger decay" instead of
408     note-off velocity.
409 schoenebeck 663 - revised voice stealing
410     (fixes crash and endless loop caused by voice stealing)
411 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
412 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
413     instead of when the respective voice is actually launched
414     (fixes undefined behavior if stolen voices belonged to a key group -
415     this case was followed by a "killed voice survived" error message)
416 schoenebeck 669 - fixed minor issue with null/silence samples
417     (those stole voices even though they don't need a voice at all which
418     resulted in "voice stealing didn't work out" messages)
419 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
420     instrument or audio output device change
421 schoenebeck 654
422 schoenebeck 620 * LSCP server:
423 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
424 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
425 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
426 schoenebeck 609
427 schoenebeck 668 * linuxsampler application:
428     - added command line parameters --lscp-addr and --lscp-port to override
429     default IP address and port of LSCP server
430    
431 schoenebeck 579 Version 0.3.1 (24 May 2005)
432    
433     * initial release
