Wed Feb 13 15:10:13 2008 UTC (11 years, 9 months ago) by schoenebeck
File size: 21238 byte(s)
- fixed di-harmonic triangle LFO implementation (this LFO implementation
  is only used by very few systems, most pick the int math
  implementation, which is usually faster)

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