File size: 20626 byte(s)
* fixed memory leaks that occurred when liblinuxsampler was unloaded
* fixed a memory leak that could happen when a channel was deleted
  while notes were playing
* fixed memory management bug in ASIO driver
* optimized the SynchronizedConfig class so it doesn't wait
  unnecessarily long after an update

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 1601
19 schoenebeck 1599 * audio driver:
20     - removed the nonsense audio channel constraint (which was hard coded to
21     max. 100 audio channels) for most audio drivers
22 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
23     opposed to the LSCP specs
24 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
25     reflected the wrong value
26 persson 1644 - fixed a memory management bug in ASIO driver
27 schoenebeck 1599
28 schoenebeck 1604 * instruments database:
29 iliev 1603 - avoid time consuming samples scanning when adding instruments
30     to the instruments database
31    
32 persson 1644 * Gigasampler format engine:
33     - fixed a memory leak that could happen when a channel was deleted
34     while notes were playing
35    
36 schoenebeck 1560 Version 0.5.1 (6 December 2007)
37 schoenebeck 1454
38     * packaging changes:
39     - added autoconf checks for pthread library
40     - added autoconf check for pthread bug found on certain NPTL-enabled
41     glibc versions (see Gentoo bug report #194076)
42 senoner 1502 - added autoconf checks for MS Windows
43 schoenebeck 1454
44 persson 1455 * general changes:
45     - bugfix: the thread used by an editor plugin didn't die when the
46     editor closed
47 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
48     out all the space. operator--() did not apply size_mask after
49     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
50     order to avoid problems with the _NonVolatileReader functions.
51     - bugfix: Stream.h: added a missing divide by BytesPerSample in
52     GetWriteSpace(). Since this function is currently only used in
53     the stream's qsort() compare function, it didn't trigger any
54     bugs.
55     - Resampler.h, Synthesizer.h: cubic interpolation now works in
56     24bit mode too. Faster method to read 24bit words on little
57     endian machines (x86): replaced 3 byte reads + shifts with a 1
58     unaligned 32bit read and shift
59     - experimental support for MS Windows (MIDI input via MME, AUDIO
60     output via ASIO)
61     - made handling of SIGINT signal (Ctrl-C) a bit more robust
62 iliev 1541 - support for monitoring the total number of active disk streams
63     (new LSCP commands: GET TOTAL_STREAM_COUNT,
64     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
65 persson 1455
66 senoner 1500 * AUDIO driver:
67 persson 1534 - added Windows ASIO low latency audio driver
68 senoner 1500
69 senoner 1485 * MIDI driver:
70 schoenebeck 1495 - added MME Windows MIDI driver
71 senoner 1485
72 schoenebeck 1471 * LSCP server:
73     - added support for Windows style path / filenames, however with
74     forward slash path separators instead of backslash
75     (i.e. "C:/foo/bar.gig")
76 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
77     apostrophes as well
78 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
79     "LIST FILE INSTRUMENTS <file>" and
80     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
81     about an arbitrary instrument file on the system where the sampler is
82     running on
83 schoenebeck 1471
84 schoenebeck 1424 Version 0.5.0 (15 October 2007)
85 schoenebeck 947
86 schoenebeck 1065 * packaging changes:
87 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
88     API header files anymore
89 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
90     the Doxygen API documentation (explicitly listed in Doxyfile.in)
91 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
92     capable to execute our autoconf environment, thus no need anymore
93     to maintain the compile time configuration file (osx/version.h) for
94     OSX manually (patch by Toshi Nagata)
95 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
96     parameters
97 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
98     C++ API header files, all implementation internal global definitions
99     are now in global_private.h
100     - atomic.h is not exposed to the C++ API anymore
101     - no need to include config.h anymore for using LS's API header files
102     - fixed warnings in API doc generation
103 schoenebeck 1065
104 schoenebeck 947 * general changes:
105     - replaced the old, confusing MIDI program change mechanism by a
106     flexible MIDI instrument mapper which allows to map arbitrary
107 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
108 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
109     loaded on the respective channel when such MIDI program change
110     messages arrive, beside that, each entry allows to define a life-time
111     strategy for the instrument, so the user can define whether the
112     instrument should i.e. be permanently loaded (to be able to switch
113     quickly among sounds) or i.e. loaded just on demand when the
114     respective program change arrives (to safe RAM space), as well as a
115     global volume factor for each entry, so the user can adjust the volume
116     dynamic of his mapped instrument collection without having to modify
117 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
118     MIDI instrument maps and assign each sampler channel individually
119     a certain map, so that i.e. separation of normal instruments and
120     drumkits is possible
121 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
122     MIDI instrument maps, MIDI instruments, FX sends, global volume.
123 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
124     due to a constant size RingBuffer FIFO which is now replaced by a
125     dynamic (unlimited) size std::list FIFO
126 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
127     output channels for being processed by external effect processors
128     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
129     controllers
130 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
131 iliev 1130 - Implemented new, improved notification system
132 schoenebeck 1149 - fixed compilation errors regarding OSX
133     (patch by Toshi Nagata)
134 iliev 1161 - implemented instruments database
135 iliev 1345 - added support for escape sequences to the instruments database
136 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
137     within the sampler's process (by using instrument editor plugins),
138     you'll notice the new "Registered instrument editors:" message on
139 schoenebeck 1407 startup, added a new LSCP command:
140     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
141 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
142     given sampler channel, the plugin path can be overridden at compile
143     time with ./configure --enable-plugin-dir=/some/dir
144 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
145     in the sampler's process to safely edit instruments while playing
146     without a crash (hopefully) by either suspending single regions
147     wherever possible or if unavoidable whole engine(s)
148 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
149     policy and priority on thread level, set a minimum stack size for
150     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
151     threads simply inherited properties of starting thread instead of
152     setting their own policy and priority
153 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
154     main process did not wait for the stack trace process to finish
155     its output
156 persson 1248 - fixed some minor memory leaks
157 schoenebeck 1259 - reenabled assembly features support, at the moment only for
158     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
159 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
160     register, to avoid relocations in the text segment at runtime)
161 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
162 schoenebeck 947
163     * MIDI driver:
164     - dispatch bank select (MSB and LSB) messages
165    
166 schoenebeck 1049 * audio driver:
167     - the ALSA audio output driver parameters now reflect the correct
168     parameter value ranges for the respective selected sound card
169     (patch by Till Wimmer, a bit fixed and extended)
170    
171 persson 951 * Gigasampler format engine:
172     - if a filter is used and EG2 finishes before EG1, let the voice
173     die when EG2 has finished (this fixes a problem with clicks and
174     voice starvation for some gigs)
175 persson 1038 - playback is no longer disabled during instrument loading
176     - all notes playing on a channel that changes its instrument keep
177     playing with the old instrument until they get a note off
178     command
179 persson 1039 - EG fix: a release value of zero could cause noises or crash
180 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
181 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
182     above max sustain level, which means that there is a decay phase
183     even if sustain is 100%
184 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
185     noises or crashes
186 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
187 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
188     supplied to the configure script (fixes #46)
189 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
190     instead of a fix value
191 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
192     127 (solo mode) only kill voices if the respective mode really
193     changed
194 persson 951
195 schoenebeck 1244 * LSCP server:
196     - fixed compile time error for old Bison versions
197     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
198 schoenebeck 1245 - parser now supports extended ASCII character set
199     (up to ASCII code 255, i.e. includes now umlauts and accents)
200     - filename arguments in LSCP commands now allow to use escape
201     sequences, that is directly literal as one of: \', \", \\, \n, \r,
202     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
203     code value like \xf2) (fixes bug #24)
204 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
205     least one of their text-based parameters (i.e. name, description):
206     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
207     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
208     "SET DB_INSTRUMENT_DIRECTORY NAME",
209     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
210     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
211     "FIND DB_INSTRUMENT_DIRECTORIES"
212 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
213     occured, the unexpected character and the actually expected, possible
214     character(s), the latter only if less than 5 possibilities)
215 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
216     settings
217 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
218     of strings were treated as being one string containing commas
219     (fixes #57)
220 schoenebeck 1244
221 iliev 959 * Bug fixes:
222     - fixed crash occurring on certain LSCP scripts (Bug 39)
223 persson 1038 - another thread safety fix for lscp "load engine" and "set
224     channel audio output device"
225 iliev 1283 - fixed a crash which occurs when reassigning the same engine
226     on a sampler channel with connected MIDI device
227 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
228     device connected to a sampler channel to number less then or equal
229     to the index of the port to which the sampler channel is connected.
230 iliev 1296 - The previous bindings were not been disconnected when altering
231     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
232     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
233 iliev 1297 - The active stream/voice count statistic was incorrect.
234 iliev 1298 - notification events were not been sent for some sampler
235     channel changes
236 iliev 1305 - added default min and max values to restrict the number of allowed
237     audio output channels and MIDI input ports
238 iliev 1306 - the connection to the PCM interface is now closed when destroying
239     an audio output device
240 schoenebeck 1332 - files with slash in their path or filename could not be loaded
241 iliev 959
242 schoenebeck 1221 * test cases:
243     - updated and fixed (haven't been touched in a while)
244    
245 schoenebeck 937 Version 0.4.0 (24 November 2006)
246 persson 696
247 schoenebeck 697 * packaging changes:
248 capela 868 - changed deprecated copyright attribute to license; added ldconfig
249     to post-(un)install steps; added devel package for liblinuxsampler;
250     to linuxsampler.spec (RPM)
251 schoenebeck 697 - install necessary development header files for allowing 3rd party
252     applications to link against liblinuxsampler
253     - liblinuxsampler's API documentation can be generated with 'make docs'
254     (Doxygen required)
255 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
256     implementation (currently either an integer math solution or a
257     di-harmonic approximation), automatic detection can be overriden
258     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
259     configure script argument though (mandatory for cross-compilation)
260 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
261     provided some on his own (as CXXFLAGS)
262 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
263     messages
264 schoenebeck 852 - added compile time options to allow disabling the various audio and
265     MIDI drivers
266 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
267     (patch by Ebrahim Mayat)
268 schoenebeck 697
269 persson 696 * Gigasampler format engine:
270 schoenebeck 738 - extensive synthesis optimization
271     (reimplementation of EGs and LFO(s), removed synthesis parameter
272     prerendering and the synthesis parameter matrix in general, splitting
273     each audio fragment into subfragments now where each subfragment uses
274 persson 830 constant pitch and filter coefficients. The volume coefficient is
275     linearly interpolated inside a subfragment, unless
276     --disable-interpolate-volume is set.)
277 persson 696 - fine tuning of the EG modulation parameters
278 persson 729 - improved filter cutoff calculation by adding support for the
279     following gig parameters: Cutoff freq (used when no cutoff
280     controller is defined), Control invert, Minimum cutoff, Velocity
281 persson 791 curve and Velocity range. The keyboard tracking now scales
282     cutoff frequency instead of resonance.
283 persson 877 - added support for gig parameter Resonance.
284 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
285 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
286     which can be overridden with --enable-global-attenuation
287 persson 783 - EG fixes: made the length of "attack hold" stage more
288     accurate. Release stage can now start before attack stage
289 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
290     time now has a minimal value to prevent clicks.
291 persson 799 - fixed pitch changes larger than one octave
292 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
293     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
294     all modes can be altered via standard GM messages, that is CC5 for
295     altering portamento time, CC65 for enabling / disabling portamento
296     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
297 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
298     parameter) and crossfade
299 persson 831 - added support for the "attenuation controller threshold" gig
300     parameter
301 persson 832 - added smoothing of volume changes caused by control change
302     messages
303 persson 865 - sample loop parameters are now taken from the DimensionRegion
304     instead of the wave chunk
305     - fixed keyswitching for v3 gigs with a number of keyswitch splits
306     not equal to a power of two
307 persson 877 - reimplementation of the filter algorithm. The new filter is more
308     accurate and supports all gig filter types, including bandreject
309     and lowpass turbo.
310 persson 903 - real support for 24 bit samples - samples are not truncated to
311     16 bits anymore
312     - support for aftertouch (channel pressure, not polyphonic
313     aftertouch)
314 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
315     amplifying from 0)
316 persson 696
317 schoenebeck 711 * LSCP server:
318     - fixed application exit on broken pipe error (fixes bug #20)
319 iliev 793 - fixed the notification messages delay due to lack of
320     network activity (fixes bug #26)
321 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
322     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
323 schoenebeck 711
324 schoenebeck 838 * audio driver:
325     - added aRts audio output driver (by no means RT safe)
326    
327 schoenebeck 775 * MIDI driver:
328     - fixed legacy sysex code which caused dispatching of MIDI SysEx
329     messages several times instead of once
330 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
331     for events (i.e. for offline rendering based MIDI drivers)
332 persson 922 - added checks for bad MIDI data
333 schoenebeck 775
334 schoenebeck 900 * linuxsampler application:
335     - show available sampler engine types on startup
336    
337 schoenebeck 705 * general changes:
338     - support for muting sampler channels and solo mode of the same, two new
339     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
340     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
341     introduced for this, the behavior is the same like on a mixer console
342 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
343     --enable-process-muted-channels which can be used to enable the
344     processing of muted channels.
345 iliev 777 - support for sostenuto pedal
346 iliev 779 - support for monitoring the total number of active voices
347 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
348     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
349 persson 835 - fixed some memory management errors
350 persson 841 - fixed some concurrency problems that could lead to crashes when
351     LSCP commands were executed
352 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
353     sampler channel (fixes bug #36)
354 schoenebeck 705
355 schoenebeck 692 Version 0.3.3 (15 July 2005)
356 schoenebeck 686
357     * packaging changes:
358     - fixed compilation with gcc 4.0
359    
360 schoenebeck 687 * Gigasampler format engine:
361     - LFO preprocessing was performed even though the respective LFO was
362     disabled by the instrument patch (minor efficiency fix)
363 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
364     for volume ramp downs in the same fragment (needed for current voice
365     stealing implementation) then simply inform the user with a warning
366     about possible click sounds and reduce the volume ramp down
367     appropriately instead of cancelling the audio device connection
368 schoenebeck 687
369 schoenebeck 677 Version 0.3.2 (24 June 2005)
370 schoenebeck 609
371     * packaging changes:
372     - updated autotools build files to compile on OS X
373     (conditional compilation of CoreMIDI and MidiShare drivers)
374 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
375     './configure --disable-asm' (definitely not recommended)
376 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
377     - require automake (>= 1.5) for 'make -f Makefile.cvs'
378     (due to 'dist-bzip2' automake option)
379 schoenebeck 649
380     * Gigasampler format engine:
381     - support for the gig parameters for "release velocity response" curves
382     - fine tuning of the EGADSR envelope
383     - volume of release triggered samples now depends on note-on velocity,
384     note length and gig parameter "release trigger decay" instead of
385     note-off velocity.
386 schoenebeck 663 - revised voice stealing
387     (fixes crash and endless loop caused by voice stealing)
388 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
389 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
390     instead of when the respective voice is actually launched
391     (fixes undefined behavior if stolen voices belonged to a key group -
392     this case was followed by a "killed voice survived" error message)
393 schoenebeck 669 - fixed minor issue with null/silence samples
394     (those stole voices even though they don't need a voice at all which
