* bugfix: JACK audio driver did not offer a device parameter
  "SAMPLERATE" as opposed to the LSCP specs which requires
  all audio drivers to provide it

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 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
14     opposed to the LSCP specs
15 schoenebeck 1599
16 schoenebeck 1604 * instruments database:
17 iliev 1603 - avoid time consuming samples scanning when adding instruments
18     to the instruments database
19    
20 schoenebeck 1560 Version 0.5.1 (6 December 2007)
21 schoenebeck 1454
22     * packaging changes:
23     - added autoconf checks for pthread library
24     - added autoconf check for pthread bug found on certain NPTL-enabled
25     glibc versions (see Gentoo bug report #194076)
26 senoner 1502 - added autoconf checks for MS Windows
27 schoenebeck 1454
28 persson 1455 * general changes:
29     - bugfix: the thread used by an editor plugin didn't die when the
30     editor closed
31 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
32     out all the space. operator--() did not apply size_mask after
33     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
34     order to avoid problems with the _NonVolatileReader functions.
35     - bugfix: Stream.h: added a missing divide by BytesPerSample in
36     GetWriteSpace(). Since this function is currently only used in
37     the stream's qsort() compare function, it didn't trigger any
38     bugs.
39     - Resampler.h, Synthesizer.h: cubic interpolation now works in
40     24bit mode too. Faster method to read 24bit words on little
41     endian machines (x86): replaced 3 byte reads + shifts with a 1
42     unaligned 32bit read and shift
43     - experimental support for MS Windows (MIDI input via MME, AUDIO
44     output via ASIO)
45     - made handling of SIGINT signal (Ctrl-C) a bit more robust
46 iliev 1541 - support for monitoring the total number of active disk streams
47     (new LSCP commands: GET TOTAL_STREAM_COUNT,
48     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
49 persson 1455
50 senoner 1500 * AUDIO driver:
51 persson 1534 - added Windows ASIO low latency audio driver
52 senoner 1500
53 senoner 1485 * MIDI driver:
54 schoenebeck 1495 - added MME Windows MIDI driver
55 senoner 1485
56 schoenebeck 1471 * LSCP server:
57     - added support for Windows style path / filenames, however with
58     forward slash path separators instead of backslash
59     (i.e. "C:/foo/bar.gig")
60 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
61     apostrophes as well
62 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
63     "LIST FILE INSTRUMENTS <file>" and
64     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
65     about an arbitrary instrument file on the system where the sampler is
66     running on
67 schoenebeck 1471
68 schoenebeck 1424 Version 0.5.0 (15 October 2007)
69 schoenebeck 947
70 schoenebeck 1065 * packaging changes:
71 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
72     API header files anymore
73 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
74     the Doxygen API documentation (explicitly listed in Doxyfile.in)
75 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
76     capable to execute our autoconf environment, thus no need anymore
77     to maintain the compile time configuration file (osx/version.h) for
78     OSX manually (patch by Toshi Nagata)
79 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
80     parameters
81 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
82     C++ API header files, all implementation internal global definitions
83     are now in global_private.h
84     - atomic.h is not exposed to the C++ API anymore
85     - no need to include config.h anymore for using LS's API header files
86     - fixed warnings in API doc generation
87 schoenebeck 1065
88 schoenebeck 947 * general changes:
89     - replaced the old, confusing MIDI program change mechanism by a
90     flexible MIDI instrument mapper which allows to map arbitrary
91 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
92 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
93     loaded on the respective channel when such MIDI program change
94     messages arrive, beside that, each entry allows to define a life-time
95     strategy for the instrument, so the user can define whether the
96     instrument should i.e. be permanently loaded (to be able to switch
97     quickly among sounds) or i.e. loaded just on demand when the
98     respective program change arrives (to safe RAM space), as well as a
99     global volume factor for each entry, so the user can adjust the volume
100     dynamic of his mapped instrument collection without having to modify
101 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
102     MIDI instrument maps and assign each sampler channel individually
103     a certain map, so that i.e. separation of normal instruments and
104     drumkits is possible
105 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
106     MIDI instrument maps, MIDI instruments, FX sends, global volume.
107 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
108     due to a constant size RingBuffer FIFO which is now replaced by a
109     dynamic (unlimited) size std::list FIFO
110 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
111     output channels for being processed by external effect processors
112     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
113     controllers
114 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
115 iliev 1130 - Implemented new, improved notification system
116 schoenebeck 1149 - fixed compilation errors regarding OSX
117     (patch by Toshi Nagata)
118 iliev 1161 - implemented instruments database
119 iliev 1345 - added support for escape sequences to the instruments database
120 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
121     within the sampler's process (by using instrument editor plugins),
122     you'll notice the new "Registered instrument editors:" message on
123 schoenebeck 1407 startup, added a new LSCP command:
124     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
125 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
126     given sampler channel, the plugin path can be overridden at compile
127     time with ./configure --enable-plugin-dir=/some/dir
128 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
129     in the sampler's process to safely edit instruments while playing
130     without a crash (hopefully) by either suspending single regions
131     wherever possible or if unavoidable whole engine(s)
132 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
133     policy and priority on thread level, set a minimum stack size for
134     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
135     threads simply inherited properties of starting thread instead of
136     setting their own policy and priority
137 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
138     main process did not wait for the stack trace process to finish
139     its output
140 persson 1248 - fixed some minor memory leaks
141 schoenebeck 1259 - reenabled assembly features support, at the moment only for
142     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
143 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
144     register, to avoid relocations in the text segment at runtime)
145 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
146 schoenebeck 947
147     * MIDI driver:
148     - dispatch bank select (MSB and LSB) messages
149    
150 schoenebeck 1049 * audio driver:
151     - the ALSA audio output driver parameters now reflect the correct
152     parameter value ranges for the respective selected sound card
153     (patch by Till Wimmer, a bit fixed and extended)
154    
155 persson 951 * Gigasampler format engine:
156     - if a filter is used and EG2 finishes before EG1, let the voice
157     die when EG2 has finished (this fixes a problem with clicks and
158     voice starvation for some gigs)
159 persson 1038 - playback is no longer disabled during instrument loading
160     - all notes playing on a channel that changes its instrument keep
161     playing with the old instrument until they get a note off
162     command
163 persson 1039 - EG fix: a release value of zero could cause noises or crash
164 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
165 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
166     above max sustain level, which means that there is a decay phase
167     even if sustain is 100%
168 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
169     noises or crashes
170 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
171 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
172     supplied to the configure script (fixes #46)
173 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
174     instead of a fix value
175 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
176     127 (solo mode) only kill voices if the respective mode really
177     changed
178 persson 951
179 schoenebeck 1244 * LSCP server:
180     - fixed compile time error for old Bison versions
181     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
182 schoenebeck 1245 - parser now supports extended ASCII character set
183     (up to ASCII code 255, i.e. includes now umlauts and accents)
184     - filename arguments in LSCP commands now allow to use escape
185     sequences, that is directly literal as one of: \', \", \\, \n, \r,
186     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
187     code value like \xf2) (fixes bug #24)
188 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
189     least one of their text-based parameters (i.e. name, description):
190     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
191     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
192     "SET DB_INSTRUMENT_DIRECTORY NAME",
193     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
194     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
195     "FIND DB_INSTRUMENT_DIRECTORIES"
196 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
197     occured, the unexpected character and the actually expected, possible
198     character(s), the latter only if less than 5 possibilities)
199 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
200     settings
201 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
202     of strings were treated as being one string containing commas
203     (fixes #57)
204 schoenebeck 1244
205 iliev 959 * Bug fixes:
206     - fixed crash occurring on certain LSCP scripts (Bug 39)
207 persson 1038 - another thread safety fix for lscp "load engine" and "set
208     channel audio output device"
209 iliev 1283 - fixed a crash which occurs when reassigning the same engine
210     on a sampler channel with connected MIDI device
211 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
212     device connected to a sampler channel to number less then or equal
213     to the index of the port to which the sampler channel is connected.
214 iliev 1296 - The previous bindings were not been disconnected when altering
215     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
216     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
217 iliev 1297 - The active stream/voice count statistic was incorrect.
218 iliev 1298 - notification events were not been sent for some sampler
219     channel changes
220 iliev 1305 - added default min and max values to restrict the number of allowed
221     audio output channels and MIDI input ports
222 iliev 1306 - the connection to the PCM interface is now closed when destroying
223     an audio output device
224 schoenebeck 1332 - files with slash in their path or filename could not be loaded
225 iliev 959
226 schoenebeck 1221 * test cases:
227     - updated and fixed (haven't been touched in a while)
228    
229 schoenebeck 937 Version 0.4.0 (24 November 2006)
230 persson 696
231 schoenebeck 697 * packaging changes:
232 capela 868 - changed deprecated copyright attribute to license; added ldconfig
233     to post-(un)install steps; added devel package for liblinuxsampler;
234     to linuxsampler.spec (RPM)
235 schoenebeck 697 - install necessary development header files for allowing 3rd party
236     applications to link against liblinuxsampler
237     - liblinuxsampler's API documentation can be generated with 'make docs'
238     (Doxygen required)
239 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
240     implementation (currently either an integer math solution or a
241     di-harmonic approximation), automatic detection can be overriden
242     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
243     configure script argument though (mandatory for cross-compilation)
244 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
245     provided some on his own (as CXXFLAGS)
246 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
247     messages
248 schoenebeck 852 - added compile time options to allow disabling the various audio and
249     MIDI drivers
250 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
251     (patch by Ebrahim Mayat)
252 schoenebeck 697
253 persson 696 * Gigasampler format engine:
254 schoenebeck 738 - extensive synthesis optimization
255     (reimplementation of EGs and LFO(s), removed synthesis parameter
256     prerendering and the synthesis parameter matrix in general, splitting
257     each audio fragment into subfragments now where each subfragment uses
258 persson 830 constant pitch and filter coefficients. The volume coefficient is
259     linearly interpolated inside a subfragment, unless
260     --disable-interpolate-volume is set.)
261 persson 696 - fine tuning of the EG modulation parameters
262 persson 729 - improved filter cutoff calculation by adding support for the
263     following gig parameters: Cutoff freq (used when no cutoff
264     controller is defined), Control invert, Minimum cutoff, Velocity
265 persson 791 curve and Velocity range. The keyboard tracking now scales
266     cutoff frequency instead of resonance.
267 persson 877 - added support for gig parameter Resonance.
268 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
269 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
270     which can be overridden with --enable-global-attenuation
271 persson 783 - EG fixes: made the length of "attack hold" stage more
272     accurate. Release stage can now start before attack stage
273 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
274     time now has a minimal value to prevent clicks.
275 persson 799 - fixed pitch changes larger than one octave
276 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
277     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
278     all modes can be altered via standard GM messages, that is CC5 for
279     altering portamento time, CC65 for enabling / disabling portamento
280     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
281 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
282     parameter) and crossfade
283 persson 831 - added support for the "attenuation controller threshold" gig
284     parameter
285 persson 832 - added smoothing of volume changes caused by control change
286     messages
287 persson 865 - sample loop parameters are now taken from the DimensionRegion
288     instead of the wave chunk
289     - fixed keyswitching for v3 gigs with a number of keyswitch splits
290     not equal to a power of two
291 persson 877 - reimplementation of the filter algorithm. The new filter is more
292     accurate and supports all gig filter types, including bandreject
293     and lowpass turbo.
294 persson 903 - real support for 24 bit samples - samples are not truncated to
295     16 bits anymore
296     - support for aftertouch (channel pressure, not polyphonic
297     aftertouch)
298 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
299     amplifying from 0)
300 persson 696
301 schoenebeck 711 * LSCP server:
302     - fixed application exit on broken pipe error (fixes bug #20)
303 iliev 793 - fixed the notification messages delay due to lack of
304     network activity (fixes bug #26)
305 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
306     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
307 schoenebeck 711
308 schoenebeck 838 * audio driver:
309     - added aRts audio output driver (by no means RT safe)
310    
311 schoenebeck 775 * MIDI driver:
312     - fixed legacy sysex code which caused dispatching of MIDI SysEx
313     messages several times instead of once
314 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
315     for events (i.e. for offline rendering based MIDI drivers)
316 persson 922 - added checks for bad MIDI data
317 schoenebeck 775
318 schoenebeck 900 * linuxsampler application:
319     - show available sampler engine types on startup
320    
321 schoenebeck 705 * general changes:
322     - support for muting sampler channels and solo mode of the same, two new
323     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
324     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
325     introduced for this, the behavior is the same like on a mixer console
326 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
327     --enable-process-muted-channels which can be used to enable the
328     processing of muted channels.
329 iliev 777 - support for sostenuto pedal
330 iliev 779 - support for monitoring the total number of active voices
331 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
332     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
333 persson 835 - fixed some memory management errors
334 persson 841 - fixed some concurrency problems that could lead to crashes when
335     LSCP commands were executed
336 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
337     sampler channel (fixes bug #36)
338 schoenebeck 705
339 schoenebeck 692 Version 0.3.3 (15 July 2005)
340 schoenebeck 686
341     * packaging changes:
342     - fixed compilation with gcc 4.0
343    
344 schoenebeck 687 * Gigasampler format engine:
345     - LFO preprocessing was performed even though the respective LFO was
346     disabled by the instrument patch (minor efficiency fix)
347 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
348     for volume ramp downs in the same fragment (needed for current voice
349     stealing implementation) then simply inform the user with a warning
350     about possible click sounds and reduce the volume ramp down
351     appropriately instead of cancelling the audio device connection
352 schoenebeck 687
353 schoenebeck 677 Version 0.3.2 (24 June 2005)
354 schoenebeck 609
355     * packaging changes:
356     - updated autotools build files to compile on OS X
357     (conditional compilation of CoreMIDI and MidiShare drivers)
358 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
359     './configure --disable-asm' (definitely not recommended)
360 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
361     - require automake (>= 1.5) for 'make -f Makefile.cvs'
362     (due to 'dist-bzip2' automake option)
363 schoenebeck 649
364     * Gigasampler format engine:
365     - support for the gig parameters for "release velocity response" curves
366     - fine tuning of the EGADSR envelope
367     - volume of release triggered samples now depends on note-on velocity,
368     note length and gig parameter "release trigger decay" instead of
369     note-off velocity.
370 schoenebeck 663 - revised voice stealing
371     (fixes crash and endless loop caused by voice stealing)
372 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
373 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
374     instead of when the respective voice is actually launched
375     (fixes undefined behavior if stolen voices belonged to a key group -
376     this case was followed by a "killed voice survived" error message)
377 schoenebeck 669 - fixed minor issue with null/silence samples
378     (those stole voices even though they don't need a voice at all which
379     resulted in "voice stealing didn't work out" messages)
380 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
381     instrument or audio output device change
382 schoenebeck 654
383 schoenebeck 620 * LSCP server:
384 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
385 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
386 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
387 schoenebeck 609
388 schoenebeck 668 * linuxsampler application:
389     - added command line parameters --lscp-addr and --lscp-port to override
390     default IP address and port of LSCP server
391    
392 schoenebeck 579 Version 0.3.1 (24 May 2005)
393    
394     * initial release
