File size: 21051 byte(s)
* added support for triggering notes by instrument editors
  (still some cleanup / refactoring ahead, but it should work)
* bumped version to 0.5.1.1cvs

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