* avoid time consuming samples scanning when
  adding instruments to the instruments database

1 schoenebeck 1599 Version CVS HEAD (?)
2    
3 schoenebeck 1601 * general changes:
4     - bugfix: on some POSIX systems instrument editor plugins refused to
5     load as we used a non-portable Linux specific struct field
6     (fixes bug #70, patch by Ronald Baljeu)
7 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
8     plugin DLL on Windows systems failed
9 schoenebeck 1601
10 schoenebeck 1599 * audio driver:
11     - removed the nonsense audio channel constraint (which was hard coded to
12     max. 100 audio channels) for most audio drivers
13    
14 iliev 1603 * instruments database
15     - avoid time consuming samples scanning when adding instruments
16     to the instruments database
17    
18 schoenebeck 1560 Version 0.5.1 (6 December 2007)
19 schoenebeck 1454
20     * packaging changes:
21     - added autoconf checks for pthread library
22     - added autoconf check for pthread bug found on certain NPTL-enabled
23     glibc versions (see Gentoo bug report #194076)
24 senoner 1502 - added autoconf checks for MS Windows
25 schoenebeck 1454
26 persson 1455 * general changes:
27     - bugfix: the thread used by an editor plugin didn't die when the
28     editor closed
29 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
30     out all the space. operator--() did not apply size_mask after
31     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
32     order to avoid problems with the _NonVolatileReader functions.
33     - bugfix: Stream.h: added a missing divide by BytesPerSample in
34     GetWriteSpace(). Since this function is currently only used in
35     the stream's qsort() compare function, it didn't trigger any
36     bugs.
37     - Resampler.h, Synthesizer.h: cubic interpolation now works in
38     24bit mode too. Faster method to read 24bit words on little
39     endian machines (x86): replaced 3 byte reads + shifts with a 1
40     unaligned 32bit read and shift
41     - experimental support for MS Windows (MIDI input via MME, AUDIO
42     output via ASIO)
43     - made handling of SIGINT signal (Ctrl-C) a bit more robust
44 iliev 1541 - support for monitoring the total number of active disk streams
45     (new LSCP commands: GET TOTAL_STREAM_COUNT,
46     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
47 persson 1455
48 senoner 1500 * AUDIO driver:
49 persson 1534 - added Windows ASIO low latency audio driver
50 senoner 1500
51 senoner 1485 * MIDI driver:
52 schoenebeck 1495 - added MME Windows MIDI driver
53 senoner 1485
54 schoenebeck 1471 * LSCP server:
55     - added support for Windows style path / filenames, however with
56     forward slash path separators instead of backslash
57     (i.e. "C:/foo/bar.gig")
58 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
59     apostrophes as well
60 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
61     "LIST FILE INSTRUMENTS <file>" and
62     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
63     about an arbitrary instrument file on the system where the sampler is
64     running on
65 schoenebeck 1471
66 schoenebeck 1424 Version 0.5.0 (15 October 2007)
67 schoenebeck 947
68 schoenebeck 1065 * packaging changes:
69 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
70     API header files anymore
71 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
72     the Doxygen API documentation (explicitly listed in Doxyfile.in)
73 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
74     capable to execute our autoconf environment, thus no need anymore
75     to maintain the compile time configuration file (osx/version.h) for
76     OSX manually (patch by Toshi Nagata)
77 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
78     parameters
79 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
80     C++ API header files, all implementation internal global definitions
81     are now in global_private.h
82     - atomic.h is not exposed to the C++ API anymore
83     - no need to include config.h anymore for using LS's API header files
84     - fixed warnings in API doc generation
85 schoenebeck 1065
86 schoenebeck 947 * general changes:
87     - replaced the old, confusing MIDI program change mechanism by a
88     flexible MIDI instrument mapper which allows to map arbitrary
89 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
90 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
91     loaded on the respective channel when such MIDI program change
92     messages arrive, beside that, each entry allows to define a life-time
93     strategy for the instrument, so the user can define whether the
94     instrument should i.e. be permanently loaded (to be able to switch
95     quickly among sounds) or i.e. loaded just on demand when the
96     respective program change arrives (to safe RAM space), as well as a
97     global volume factor for each entry, so the user can adjust the volume
98     dynamic of his mapped instrument collection without having to modify
99 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
100     MIDI instrument maps and assign each sampler channel individually
101     a certain map, so that i.e. separation of normal instruments and
102     drumkits is possible
103 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
104     MIDI instrument maps, MIDI instruments, FX sends, global volume.
105 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
106     due to a constant size RingBuffer FIFO which is now replaced by a
107     dynamic (unlimited) size std::list FIFO
108 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
109     output channels for being processed by external effect processors
110     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
111     controllers
112 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
113 iliev 1130 - Implemented new, improved notification system
114 schoenebeck 1149 - fixed compilation errors regarding OSX
115     (patch by Toshi Nagata)
116 iliev 1161 - implemented instruments database
117 iliev 1345 - added support for escape sequences to the instruments database
118 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
119     within the sampler's process (by using instrument editor plugins),
120     you'll notice the new "Registered instrument editors:" message on
121 schoenebeck 1407 startup, added a new LSCP command:
122     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
123 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
124     given sampler channel, the plugin path can be overridden at compile
125     time with ./configure --enable-plugin-dir=/some/dir
126 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
127     in the sampler's process to safely edit instruments while playing
128     without a crash (hopefully) by either suspending single regions
129     wherever possible or if unavoidable whole engine(s)
130 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
131     policy and priority on thread level, set a minimum stack size for
132     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
133     threads simply inherited properties of starting thread instead of
134     setting their own policy and priority
135 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
136     main process did not wait for the stack trace process to finish
137     its output
138 persson 1248 - fixed some minor memory leaks
139 schoenebeck 1259 - reenabled assembly features support, at the moment only for
140     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
141 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
142     register, to avoid relocations in the text segment at runtime)
143 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
144 schoenebeck 947
145     * MIDI driver:
146     - dispatch bank select (MSB and LSB) messages
147    
148 schoenebeck 1049 * audio driver:
149     - the ALSA audio output driver parameters now reflect the correct
150     parameter value ranges for the respective selected sound card
151     (patch by Till Wimmer, a bit fixed and extended)
152    
153 persson 951 * Gigasampler format engine:
154     - if a filter is used and EG2 finishes before EG1, let the voice
155     die when EG2 has finished (this fixes a problem with clicks and
156     voice starvation for some gigs)
157 persson 1038 - playback is no longer disabled during instrument loading
158     - all notes playing on a channel that changes its instrument keep
159     playing with the old instrument until they get a note off
160     command
161 persson 1039 - EG fix: a release value of zero could cause noises or crash
162 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
163 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
164     above max sustain level, which means that there is a decay phase
165     even if sustain is 100%
166 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
167     noises or crashes
168 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
169 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
170     supplied to the configure script (fixes #46)
171 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
172     instead of a fix value
173 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
174     127 (solo mode) only kill voices if the respective mode really
175     changed
176 persson 951
177 schoenebeck 1244 * LSCP server:
178     - fixed compile time error for old Bison versions
179     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
180 schoenebeck 1245 - parser now supports extended ASCII character set
181     (up to ASCII code 255, i.e. includes now umlauts and accents)
182     - filename arguments in LSCP commands now allow to use escape
183     sequences, that is directly literal as one of: \', \", \\, \n, \r,
184     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
185     code value like \xf2) (fixes bug #24)
186 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
187     least one of their text-based parameters (i.e. name, description):
188     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
189     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
190     "SET DB_INSTRUMENT_DIRECTORY NAME",
191     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
192     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
193     "FIND DB_INSTRUMENT_DIRECTORIES"
194 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
195     occured, the unexpected character and the actually expected, possible
196     character(s), the latter only if less than 5 possibilities)
197 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
198     settings
199 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
200     of strings were treated as being one string containing commas
201     (fixes #57)
202 schoenebeck 1244
203 iliev 959 * Bug fixes:
204     - fixed crash occurring on certain LSCP scripts (Bug 39)
205 persson 1038 - another thread safety fix for lscp "load engine" and "set
206     channel audio output device"
207 iliev 1283 - fixed a crash which occurs when reassigning the same engine
208     on a sampler channel with connected MIDI device
209 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
210     device connected to a sampler channel to number less then or equal
211     to the index of the port to which the sampler channel is connected.
212 iliev 1296 - The previous bindings were not been disconnected when altering
213     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
214     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
215 iliev 1297 - The active stream/voice count statistic was incorrect.
216 iliev 1298 - notification events were not been sent for some sampler
217     channel changes
218 iliev 1305 - added default min and max values to restrict the number of allowed
219     audio output channels and MIDI input ports
220 iliev 1306 - the connection to the PCM interface is now closed when destroying
221     an audio output device
222 schoenebeck 1332 - files with slash in their path or filename could not be loaded
223 iliev 959
224 schoenebeck 1221 * test cases:
225     - updated and fixed (haven't been touched in a while)
226    
227 schoenebeck 937 Version 0.4.0 (24 November 2006)
228 persson 696
229 schoenebeck 697 * packaging changes:
230 capela 868 - changed deprecated copyright attribute to license; added ldconfig
231     to post-(un)install steps; added devel package for liblinuxsampler;
232     to linuxsampler.spec (RPM)
233 schoenebeck 697 - install necessary development header files for allowing 3rd party
234     applications to link against liblinuxsampler
235     - liblinuxsampler's API documentation can be generated with 'make docs'
236     (Doxygen required)
237 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
238     implementation (currently either an integer math solution or a
239     di-harmonic approximation), automatic detection can be overriden
240     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
241     configure script argument though (mandatory for cross-compilation)
242 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
243     provided some on his own (as CXXFLAGS)
244 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
245     messages
246 schoenebeck 852 - added compile time options to allow disabling the various audio and
247     MIDI drivers
248 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
249     (patch by Ebrahim Mayat)
250 schoenebeck 697
251 persson 696 * Gigasampler format engine:
252 schoenebeck 738 - extensive synthesis optimization
253     (reimplementation of EGs and LFO(s), removed synthesis parameter
254     prerendering and the synthesis parameter matrix in general, splitting
255     each audio fragment into subfragments now where each subfragment uses
256 persson 830 constant pitch and filter coefficients. The volume coefficient is
257     linearly interpolated inside a subfragment, unless
258     --disable-interpolate-volume is set.)
259 persson 696 - fine tuning of the EG modulation parameters
260 persson 729 - improved filter cutoff calculation by adding support for the
261     following gig parameters: Cutoff freq (used when no cutoff
262     controller is defined), Control invert, Minimum cutoff, Velocity
263 persson 791 curve and Velocity range. The keyboard tracking now scales
264     cutoff frequency instead of resonance.
265 persson 877 - added support for gig parameter Resonance.
266 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
267 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
268     which can be overridden with --enable-global-attenuation
269 persson 783 - EG fixes: made the length of "attack hold" stage more
270     accurate. Release stage can now start before attack stage
271 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
272     time now has a minimal value to prevent clicks.
273 persson 799 - fixed pitch changes larger than one octave
274 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
275     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
276     all modes can be altered via standard GM messages, that is CC5 for
277     altering portamento time, CC65 for enabling / disabling portamento
278     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
279 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
280     parameter) and crossfade
281 persson 831 - added support for the "attenuation controller threshold" gig
282     parameter
283 persson 832 - added smoothing of volume changes caused by control change
284     messages
285 persson 865 - sample loop parameters are now taken from the DimensionRegion
286     instead of the wave chunk
287     - fixed keyswitching for v3 gigs with a number of keyswitch splits
288     not equal to a power of two
289 persson 877 - reimplementation of the filter algorithm. The new filter is more
290     accurate and supports all gig filter types, including bandreject
291     and lowpass turbo.
292 persson 903 - real support for 24 bit samples - samples are not truncated to
293     16 bits anymore
294     - support for aftertouch (channel pressure, not polyphonic
295     aftertouch)
296 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
297     amplifying from 0)
298 persson 696
299 schoenebeck 711 * LSCP server:
300     - fixed application exit on broken pipe error (fixes bug #20)
301 iliev 793 - fixed the notification messages delay due to lack of
302     network activity (fixes bug #26)
303 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
304     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
305 schoenebeck 711
306 schoenebeck 838 * audio driver:
307     - added aRts audio output driver (by no means RT safe)
308    
309 schoenebeck 775 * MIDI driver:
310     - fixed legacy sysex code which caused dispatching of MIDI SysEx
311     messages several times instead of once
312 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
313     for events (i.e. for offline rendering based MIDI drivers)
314 persson 922 - added checks for bad MIDI data
315 schoenebeck 775
316 schoenebeck 900 * linuxsampler application:
317     - show available sampler engine types on startup
318    
319 schoenebeck 705 * general changes:
320     - support for muting sampler channels and solo mode of the same, two new
321     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
322     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
323     introduced for this, the behavior is the same like on a mixer console
324 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
325     --enable-process-muted-channels which can be used to enable the
326     processing of muted channels.
327 iliev 777 - support for sostenuto pedal
328 iliev 779 - support for monitoring the total number of active voices
329 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
330     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
331 persson 835 - fixed some memory management errors
332 persson 841 - fixed some concurrency problems that could lead to crashes when
333     LSCP commands were executed
334 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
335     sampler channel (fixes bug #36)
336 schoenebeck 705
337 schoenebeck 692 Version 0.3.3 (15 July 2005)
338 schoenebeck 686
339     * packaging changes:
340     - fixed compilation with gcc 4.0
341    
342 schoenebeck 687 * Gigasampler format engine:
343     - LFO preprocessing was performed even though the respective LFO was
344     disabled by the instrument patch (minor efficiency fix)
345 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
346     for volume ramp downs in the same fragment (needed for current voice
347     stealing implementation) then simply inform the user with a warning
348     about possible click sounds and reduce the volume ramp down
349     appropriately instead of cancelling the audio device connection
350 schoenebeck 687
351 schoenebeck 677 Version 0.3.2 (24 June 2005)
352 schoenebeck 609
353     * packaging changes:
354     - updated autotools build files to compile on OS X
355     (conditional compilation of CoreMIDI and MidiShare drivers)
356 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
357     './configure --disable-asm' (definitely not recommended)
358 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
359     - require automake (>= 1.5) for 'make -f Makefile.cvs'
360     (due to 'dist-bzip2' automake option)
361 schoenebeck 649
362     * Gigasampler format engine:
363     - support for the gig parameters for "release velocity response" curves
364     - fine tuning of the EGADSR envelope
365     - volume of release triggered samples now depends on note-on velocity,
366     note length and gig parameter "release trigger decay" instead of
367     note-off velocity.
368 schoenebeck 663 - revised voice stealing
369     (fixes crash and endless loop caused by voice stealing)
370 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
371 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
372     instead of when the respective voice is actually launched
373     (fixes undefined behavior if stolen voices belonged to a key group -
374     this case was followed by a "killed voice survived" error message)
375 schoenebeck 669 - fixed minor issue with null/silence samples
376     (those stole voices even though they don't need a voice at all which
377     resulted in "voice stealing didn't work out" messages)
378 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
379     instrument or audio output device change
380 schoenebeck 654
381 schoenebeck 620 * LSCP server:
382 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
383 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
384 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
385 schoenebeck 609
386 schoenebeck 668 * linuxsampler application:
387     - added command line parameters --lscp-addr and --lscp-port to override
388     default IP address and port of LSCP server
389    
390 schoenebeck 579 Version 0.3.1 (24 May 2005)
391    
392     * initial release
