File size: 21687 byte(s)
* added new LSCP event "DEVICE_MIDI" which can be used by frontends to
  react on MIDI data arriving on certain MIDI input devices (so far only
  Note-On and Note-Off events are sent via this LSCP event)
* bumped version to 0.5.1.4cvs

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