- bumped LS version to 0.5.1.3cvs

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