* made it possible to load an instrument even if the audio thread
  isn't running

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 persson 1646 - made it possible to load an instrument even if the audio thread
36     isn't running
37 persson 1644
38 schoenebeck 1560 Version 0.5.1 (6 December 2007)
39 schoenebeck 1454
40     * packaging changes:
41     - added autoconf checks for pthread library
42     - added autoconf check for pthread bug found on certain NPTL-enabled
43     glibc versions (see Gentoo bug report #194076)
44 senoner 1502 - added autoconf checks for MS Windows
45 schoenebeck 1454
46 persson 1455 * general changes:
47     - bugfix: the thread used by an editor plugin didn't die when the
48     editor closed
49 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
50     out all the space. operator--() did not apply size_mask after
51     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
52     order to avoid problems with the _NonVolatileReader functions.
53     - bugfix: Stream.h: added a missing divide by BytesPerSample in
54     GetWriteSpace(). Since this function is currently only used in
55     the stream's qsort() compare function, it didn't trigger any
56     bugs.
57     - Resampler.h, Synthesizer.h: cubic interpolation now works in
58     24bit mode too. Faster method to read 24bit words on little
59     endian machines (x86): replaced 3 byte reads + shifts with a 1
60     unaligned 32bit read and shift
61     - experimental support for MS Windows (MIDI input via MME, AUDIO
62     output via ASIO)
63     - made handling of SIGINT signal (Ctrl-C) a bit more robust
64 iliev 1541 - support for monitoring the total number of active disk streams
65     (new LSCP commands: GET TOTAL_STREAM_COUNT,
66     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
67 persson 1455
68 senoner 1500 * AUDIO driver:
69 persson 1534 - added Windows ASIO low latency audio driver
70 senoner 1500
71 senoner 1485 * MIDI driver:
72 schoenebeck 1495 - added MME Windows MIDI driver
73 senoner 1485
74 schoenebeck 1471 * LSCP server:
75     - added support for Windows style path / filenames, however with
76     forward slash path separators instead of backslash
77     (i.e. "C:/foo/bar.gig")
78 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
79     apostrophes as well
80 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
81     "LIST FILE INSTRUMENTS <file>" and
82     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
83     about an arbitrary instrument file on the system where the sampler is
84     running on
85 schoenebeck 1471
86 schoenebeck 1424 Version 0.5.0 (15 October 2007)
87 schoenebeck 947
88 schoenebeck 1065 * packaging changes:
89 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
90     API header files anymore
91 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
92     the Doxygen API documentation (explicitly listed in Doxyfile.in)
93 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
94     capable to execute our autoconf environment, thus no need anymore
95     to maintain the compile time configuration file (osx/version.h) for
96     OSX manually (patch by Toshi Nagata)
97 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
98     parameters
99 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
100     C++ API header files, all implementation internal global definitions
101     are now in global_private.h
102     - atomic.h is not exposed to the C++ API anymore
103     - no need to include config.h anymore for using LS's API header files
104     - fixed warnings in API doc generation
105 schoenebeck 1065
106 schoenebeck 947 * general changes:
107     - replaced the old, confusing MIDI program change mechanism by a
108     flexible MIDI instrument mapper which allows to map arbitrary
109 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
110 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
111     loaded on the respective channel when such MIDI program change
112     messages arrive, beside that, each entry allows to define a life-time
113     strategy for the instrument, so the user can define whether the
114     instrument should i.e. be permanently loaded (to be able to switch
115     quickly among sounds) or i.e. loaded just on demand when the
116     respective program change arrives (to safe RAM space), as well as a
117     global volume factor for each entry, so the user can adjust the volume
118     dynamic of his mapped instrument collection without having to modify
119 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
120     MIDI instrument maps and assign each sampler channel individually
121     a certain map, so that i.e. separation of normal instruments and
122     drumkits is possible
123 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
124     MIDI instrument maps, MIDI instruments, FX sends, global volume.
125 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
126     due to a constant size RingBuffer FIFO which is now replaced by a
127     dynamic (unlimited) size std::list FIFO
128 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
129     output channels for being processed by external effect processors
130     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
131     controllers
132 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
133 iliev 1130 - Implemented new, improved notification system
134 schoenebeck 1149 - fixed compilation errors regarding OSX
135     (patch by Toshi Nagata)
136 iliev 1161 - implemented instruments database
137 iliev 1345 - added support for escape sequences to the instruments database
138 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
139     within the sampler's process (by using instrument editor plugins),
140     you'll notice the new "Registered instrument editors:" message on
141 schoenebeck 1407 startup, added a new LSCP command:
142     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
143 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
144     given sampler channel, the plugin path can be overridden at compile
145     time with ./configure --enable-plugin-dir=/some/dir
146 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
147     in the sampler's process to safely edit instruments while playing
148     without a crash (hopefully) by either suspending single regions
149     wherever possible or if unavoidable whole engine(s)
150 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
151     policy and priority on thread level, set a minimum stack size for
152     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
153     threads simply inherited properties of starting thread instead of
154     setting their own policy and priority
155 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
156     main process did not wait for the stack trace process to finish
157     its output
158 persson 1248 - fixed some minor memory leaks
159 schoenebeck 1259 - reenabled assembly features support, at the moment only for
160     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
161 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
162     register, to avoid relocations in the text segment at runtime)
163 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
164 schoenebeck 947
165     * MIDI driver:
166     - dispatch bank select (MSB and LSB) messages
167    
168 schoenebeck 1049 * audio driver:
169     - the ALSA audio output driver parameters now reflect the correct
170     parameter value ranges for the respective selected sound card
171     (patch by Till Wimmer, a bit fixed and extended)
172    
173 persson 951 * Gigasampler format engine:
174     - if a filter is used and EG2 finishes before EG1, let the voice
175     die when EG2 has finished (this fixes a problem with clicks and
176     voice starvation for some gigs)
177 persson 1038 - playback is no longer disabled during instrument loading
178     - all notes playing on a channel that changes its instrument keep
179     playing with the old instrument until they get a note off
180     command
181 persson 1039 - EG fix: a release value of zero could cause noises or crash
182 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
183 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
184     above max sustain level, which means that there is a decay phase
185     even if sustain is 100%
186 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
187     noises or crashes
188 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
189 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
190     supplied to the configure script (fixes #46)
191 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
192     instead of a fix value
193 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
194     127 (solo mode) only kill voices if the respective mode really
195     changed
196 persson 951
197 schoenebeck 1244 * LSCP server:
198     - fixed compile time error for old Bison versions
199     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
200 schoenebeck 1245 - parser now supports extended ASCII character set
201     (up to ASCII code 255, i.e. includes now umlauts and accents)
202     - filename arguments in LSCP commands now allow to use escape
203     sequences, that is directly literal as one of: \', \", \\, \n, \r,
204     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
205     code value like \xf2) (fixes bug #24)
206 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
207     least one of their text-based parameters (i.e. name, description):
208     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
209     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
210     "SET DB_INSTRUMENT_DIRECTORY NAME",
211     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
212     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
213     "FIND DB_INSTRUMENT_DIRECTORIES"
214 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
215     occured, the unexpected character and the actually expected, possible
216     character(s), the latter only if less than 5 possibilities)
217 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
218     settings
219 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
220     of strings were treated as being one string containing commas
221     (fixes #57)
222 schoenebeck 1244
223 iliev 959 * Bug fixes:
224     - fixed crash occurring on certain LSCP scripts (Bug 39)
225 persson 1038 - another thread safety fix for lscp "load engine" and "set
226     channel audio output device"
227 iliev 1283 - fixed a crash which occurs when reassigning the same engine
228     on a sampler channel with connected MIDI device
229 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
230     device connected to a sampler channel to number less then or equal
231     to the index of the port to which the sampler channel is connected.
232 iliev 1296 - The previous bindings were not been disconnected when altering
233     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
234     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
235 iliev 1297 - The active stream/voice count statistic was incorrect.
236 iliev 1298 - notification events were not been sent for some sampler
237     channel changes
238 iliev 1305 - added default min and max values to restrict the number of allowed
239     audio output channels and MIDI input ports
240 iliev 1306 - the connection to the PCM interface is now closed when destroying
241     an audio output device
242 schoenebeck 1332 - files with slash in their path or filename could not be loaded
243 iliev 959
244 schoenebeck 1221 * test cases:
245     - updated and fixed (haven't been touched in a while)
246    
247 schoenebeck 937 Version 0.4.0 (24 November 2006)
248 persson 696
249 schoenebeck 697 * packaging changes:
250 capela 868 - changed deprecated copyright attribute to license; added ldconfig
251     to post-(un)install steps; added devel package for liblinuxsampler;
252     to linuxsampler.spec (RPM)
253 schoenebeck 697 - install necessary development header files for allowing 3rd party
254     applications to link against liblinuxsampler
255     - liblinuxsampler's API documentation can be generated with 'make docs'
256     (Doxygen required)
257 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
258     implementation (currently either an integer math solution or a
259     di-harmonic approximation), automatic detection can be overriden
260     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
261     configure script argument though (mandatory for cross-compilation)
262 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
263     provided some on his own (as CXXFLAGS)
264 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
265     messages
266 schoenebeck 852 - added compile time options to allow disabling the various audio and
267     MIDI drivers
268 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
269     (patch by Ebrahim Mayat)
270 schoenebeck 697
271 persson 696 * Gigasampler format engine:
272 schoenebeck 738 - extensive synthesis optimization
273     (reimplementation of EGs and LFO(s), removed synthesis parameter
274     prerendering and the synthesis parameter matrix in general, splitting
275     each audio fragment into subfragments now where each subfragment uses
276 persson 830 constant pitch and filter coefficients. The volume coefficient is
277     linearly interpolated inside a subfragment, unless
278     --disable-interpolate-volume is set.)
279 persson 696 - fine tuning of the EG modulation parameters
280 persson 729 - improved filter cutoff calculation by adding support for the
281     following gig parameters: Cutoff freq (used when no cutoff
282     controller is defined), Control invert, Minimum cutoff, Velocity
283 persson 791 curve and Velocity range. The keyboard tracking now scales
284     cutoff frequency instead of resonance.
285 persson 877 - added support for gig parameter Resonance.
286 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
287 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
288     which can be overridden with --enable-global-attenuation
289 persson 783 - EG fixes: made the length of "attack hold" stage more
290     accurate. Release stage can now start before attack stage
291 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
292     time now has a minimal value to prevent clicks.
293 persson 799 - fixed pitch changes larger than one octave
294 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
295     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
296     all modes can be altered via standard GM messages, that is CC5 for
297     altering portamento time, CC65 for enabling / disabling portamento
298     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
299 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
300     parameter) and crossfade
301 persson 831 - added support for the "attenuation controller threshold" gig
302     parameter
303 persson 832 - added smoothing of volume changes caused by control change
304     messages
305 persson 865 - sample loop parameters are now taken from the DimensionRegion
306     instead of the wave chunk
307     - fixed keyswitching for v3 gigs with a number of keyswitch splits
308     not equal to a power of two
309 persson 877 - reimplementation of the filter algorithm. The new filter is more
310     accurate and supports all gig filter types, including bandreject
311     and lowpass turbo.
312 persson 903 - real support for 24 bit samples - samples are not truncated to
313     16 bits anymore
314     - support for aftertouch (channel pressure, not polyphonic
315     aftertouch)
316 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
317     amplifying from 0)
318 persson 696
319 schoenebeck 711 * LSCP server:
320     - fixed application exit on broken pipe error (fixes bug #20)
321 iliev 793 - fixed the notification messages delay due to lack of
322     network activity (fixes bug #26)
323 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
324     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
325 schoenebeck 711
326 schoenebeck 838 * audio driver:
327     - added aRts audio output driver (by no means RT safe)
328    
329 schoenebeck 775 * MIDI driver:
330     - fixed legacy sysex code which caused dispatching of MIDI SysEx
331     messages several times instead of once
332 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
333     for events (i.e. for offline rendering based MIDI drivers)
334 persson 922 - added checks for bad MIDI data
335 schoenebeck 775
336 schoenebeck 900 * linuxsampler application:
337     - show available sampler engine types on startup
338    
339 schoenebeck 705 * general changes:
340     - support for muting sampler channels and solo mode of the same, two new
341     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
342     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
343     introduced for this, the behavior is the same like on a mixer console
344 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
345     --enable-process-muted-channels which can be used to enable the
346     processing of muted channels.
347 iliev 777 - support for sostenuto pedal
348 iliev 779 - support for monitoring the total number of active voices
349 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
350     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
351 persson 835 - fixed some memory management errors
352 persson 841 - fixed some concurrency problems that could lead to crashes when
353     LSCP commands were executed
354 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
355     sampler channel (fixes bug #36)
356 schoenebeck 705
357 schoenebeck 692 Version 0.3.3 (15 July 2005)
358 schoenebeck 686
359     * packaging changes:
360     - fixed compilation with gcc 4.0
361    
362 schoenebeck 687 * Gigasampler format engine:
363     - LFO preprocessing was performed even though the respective LFO was
364     disabled by the instrument patch (minor efficiency fix)
365 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
366     for volume ramp downs in the same fragment (needed for current voice
367     stealing implementation) then simply inform the user with a warning
368     about possible click sounds and reduce the volume ramp down
369     appropriately instead of cancelling the audio device connection
370 schoenebeck 687
371 schoenebeck 677 Version 0.3.2 (24 June 2005)
372 schoenebeck 609
373     * packaging changes:
374     - updated autotools build files to compile on OS X
375     (conditional compilation of CoreMIDI and MidiShare drivers)
376 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
377     './configure --disable-asm' (definitely not recommended)
378 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
379     - require automake (>= 1.5) for 'make -f Makefile.cvs'
380     (due to 'dist-bzip2' automake option)
381 schoenebeck 649
382     * Gigasampler format engine:
383     - support for the gig parameters for "release velocity response" curves
384     - fine tuning of the EGADSR envelope
385     - volume of release triggered samples now depends on note-on velocity,
386     note length and gig parameter "release trigger decay" instead of
387     note-off velocity.
388 schoenebeck 663 - revised voice stealing
389     (fixes crash and endless loop caused by voice stealing)
390 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
391 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
392     instead of when the respective voice is actually launched
393     (fixes undefined behavior if stolen voices belonged to a key group -
394     this case was followed by a "killed voice survived" error message)
395 schoenebeck 669 - fixed minor issue with null/silence samples
396     (those stole voices even though they don't need a voice at all which
