File size: 20976 byte(s)
* added support for notifying instrument editors on note-on / note-off
  events (e.g. to highlight the pressed keys on the virtual keyboard
  of gigedit)
* fixed return value of recently added Thread::TestCancel() method
* be verbose on DLL load errors (on Linux)

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