* bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
  reflected the wrong value

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 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
16     reflected the wrong value
17 schoenebeck 1599
18 schoenebeck 1604 * instruments database:
19 iliev 1603 - avoid time consuming samples scanning when adding instruments
20     to the instruments database
21    
22 schoenebeck 1560 Version 0.5.1 (6 December 2007)
23 schoenebeck 1454
24     * packaging changes:
25     - added autoconf checks for pthread library
26     - added autoconf check for pthread bug found on certain NPTL-enabled
27     glibc versions (see Gentoo bug report #194076)
28 senoner 1502 - added autoconf checks for MS Windows
29 schoenebeck 1454
30 persson 1455 * general changes:
31     - bugfix: the thread used by an editor plugin didn't die when the
32     editor closed
33 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
34     out all the space. operator--() did not apply size_mask after
35     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
36     order to avoid problems with the _NonVolatileReader functions.
37     - bugfix: Stream.h: added a missing divide by BytesPerSample in
38     GetWriteSpace(). Since this function is currently only used in
39     the stream's qsort() compare function, it didn't trigger any
40     bugs.
41     - Resampler.h, Synthesizer.h: cubic interpolation now works in
42     24bit mode too. Faster method to read 24bit words on little
43     endian machines (x86): replaced 3 byte reads + shifts with a 1
44     unaligned 32bit read and shift
45     - experimental support for MS Windows (MIDI input via MME, AUDIO
46     output via ASIO)
47     - made handling of SIGINT signal (Ctrl-C) a bit more robust
48 iliev 1541 - support for monitoring the total number of active disk streams
49     (new LSCP commands: GET TOTAL_STREAM_COUNT,
50     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
51 persson 1455
52 senoner 1500 * AUDIO driver:
53 persson 1534 - added Windows ASIO low latency audio driver
54 senoner 1500
55 senoner 1485 * MIDI driver:
56 schoenebeck 1495 - added MME Windows MIDI driver
57 senoner 1485
58 schoenebeck 1471 * LSCP server:
59     - added support for Windows style path / filenames, however with
60     forward slash path separators instead of backslash
61     (i.e. "C:/foo/bar.gig")
62 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
63     apostrophes as well
64 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
65     "LIST FILE INSTRUMENTS <file>" and
66     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
67     about an arbitrary instrument file on the system where the sampler is
68     running on
69 schoenebeck 1471
70 schoenebeck 1424 Version 0.5.0 (15 October 2007)
71 schoenebeck 947
72 schoenebeck 1065 * packaging changes:
73 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
74     API header files anymore
75 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
76     the Doxygen API documentation (explicitly listed in Doxyfile.in)
77 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
78     capable to execute our autoconf environment, thus no need anymore
79     to maintain the compile time configuration file (osx/version.h) for
80     OSX manually (patch by Toshi Nagata)
81 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
82     parameters
83 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
84     C++ API header files, all implementation internal global definitions
85     are now in global_private.h
86     - atomic.h is not exposed to the C++ API anymore
87     - no need to include config.h anymore for using LS's API header files
88     - fixed warnings in API doc generation
89 schoenebeck 1065
90 schoenebeck 947 * general changes:
91     - replaced the old, confusing MIDI program change mechanism by a
92     flexible MIDI instrument mapper which allows to map arbitrary
93 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
94 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
95     loaded on the respective channel when such MIDI program change
96     messages arrive, beside that, each entry allows to define a life-time
97     strategy for the instrument, so the user can define whether the
98     instrument should i.e. be permanently loaded (to be able to switch
99     quickly among sounds) or i.e. loaded just on demand when the
100     respective program change arrives (to safe RAM space), as well as a
101     global volume factor for each entry, so the user can adjust the volume
102     dynamic of his mapped instrument collection without having to modify
103 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
104     MIDI instrument maps and assign each sampler channel individually
105     a certain map, so that i.e. separation of normal instruments and
106     drumkits is possible
107 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
108     MIDI instrument maps, MIDI instruments, FX sends, global volume.
109 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
110     due to a constant size RingBuffer FIFO which is now replaced by a
111     dynamic (unlimited) size std::list FIFO
112 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
113     output channels for being processed by external effect processors
114     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
115     controllers
116 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
117 iliev 1130 - Implemented new, improved notification system
118 schoenebeck 1149 - fixed compilation errors regarding OSX
119     (patch by Toshi Nagata)
120 iliev 1161 - implemented instruments database
121 iliev 1345 - added support for escape sequences to the instruments database
122 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
123     within the sampler's process (by using instrument editor plugins),
124     you'll notice the new "Registered instrument editors:" message on
125 schoenebeck 1407 startup, added a new LSCP command:
126     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
127 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
128     given sampler channel, the plugin path can be overridden at compile
129     time with ./configure --enable-plugin-dir=/some/dir
130 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
131     in the sampler's process to safely edit instruments while playing
132     without a crash (hopefully) by either suspending single regions
133     wherever possible or if unavoidable whole engine(s)
134 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
135     policy and priority on thread level, set a minimum stack size for
136     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
137     threads simply inherited properties of starting thread instead of
138     setting their own policy and priority
139 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
140     main process did not wait for the stack trace process to finish
141     its output
142 persson 1248 - fixed some minor memory leaks
143 schoenebeck 1259 - reenabled assembly features support, at the moment only for
144     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
145 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
146     register, to avoid relocations in the text segment at runtime)
147 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
148 schoenebeck 947
149     * MIDI driver:
150     - dispatch bank select (MSB and LSB) messages
151    
152 schoenebeck 1049 * audio driver:
153     - the ALSA audio output driver parameters now reflect the correct
154     parameter value ranges for the respective selected sound card
155     (patch by Till Wimmer, a bit fixed and extended)
156    
157 persson 951 * Gigasampler format engine:
158     - if a filter is used and EG2 finishes before EG1, let the voice
159     die when EG2 has finished (this fixes a problem with clicks and
160     voice starvation for some gigs)
161 persson 1038 - playback is no longer disabled during instrument loading
162     - all notes playing on a channel that changes its instrument keep
163     playing with the old instrument until they get a note off
164     command
165 persson 1039 - EG fix: a release value of zero could cause noises or crash
166 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
167 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
168     above max sustain level, which means that there is a decay phase
169     even if sustain is 100%
170 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
171     noises or crashes
172 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
173 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
174     supplied to the configure script (fixes #46)
175 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
176     instead of a fix value
177 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
178     127 (solo mode) only kill voices if the respective mode really
179     changed
180 persson 951
181 schoenebeck 1244 * LSCP server:
182     - fixed compile time error for old Bison versions
183     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
184 schoenebeck 1245 - parser now supports extended ASCII character set
185     (up to ASCII code 255, i.e. includes now umlauts and accents)
186     - filename arguments in LSCP commands now allow to use escape
187     sequences, that is directly literal as one of: \', \", \\, \n, \r,
188     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
189     code value like \xf2) (fixes bug #24)
190 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
191     least one of their text-based parameters (i.e. name, description):
192     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
193     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
194     "SET DB_INSTRUMENT_DIRECTORY NAME",
195     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
196     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
197     "FIND DB_INSTRUMENT_DIRECTORIES"
198 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
199     occured, the unexpected character and the actually expected, possible
200     character(s), the latter only if less than 5 possibilities)
201 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
202     settings
203 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
204     of strings were treated as being one string containing commas
205     (fixes #57)
206 schoenebeck 1244
207 iliev 959 * Bug fixes:
208     - fixed crash occurring on certain LSCP scripts (Bug 39)
209 persson 1038 - another thread safety fix for lscp "load engine" and "set
210     channel audio output device"
211 iliev 1283 - fixed a crash which occurs when reassigning the same engine
212     on a sampler channel with connected MIDI device
213 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
214     device connected to a sampler channel to number less then or equal
215     to the index of the port to which the sampler channel is connected.
216 iliev 1296 - The previous bindings were not been disconnected when altering
217     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
218     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
219 iliev 1297 - The active stream/voice count statistic was incorrect.
220 iliev 1298 - notification events were not been sent for some sampler
221     channel changes
222 iliev 1305 - added default min and max values to restrict the number of allowed
223     audio output channels and MIDI input ports
224 iliev 1306 - the connection to the PCM interface is now closed when destroying
225     an audio output device
226 schoenebeck 1332 - files with slash in their path or filename could not be loaded
227 iliev 959
228 schoenebeck 1221 * test cases:
229     - updated and fixed (haven't been touched in a while)
230    
231 schoenebeck 937 Version 0.4.0 (24 November 2006)
232 persson 696
233 schoenebeck 697 * packaging changes:
234 capela 868 - changed deprecated copyright attribute to license; added ldconfig
235     to post-(un)install steps; added devel package for liblinuxsampler;
236     to linuxsampler.spec (RPM)
237 schoenebeck 697 - install necessary development header files for allowing 3rd party
238     applications to link against liblinuxsampler
239     - liblinuxsampler's API documentation can be generated with 'make docs'
240     (Doxygen required)
241 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
242     implementation (currently either an integer math solution or a
243     di-harmonic approximation), automatic detection can be overriden
244     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
245     configure script argument though (mandatory for cross-compilation)
246 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
247     provided some on his own (as CXXFLAGS)
248 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
249     messages
250 schoenebeck 852 - added compile time options to allow disabling the various audio and
251     MIDI drivers
252 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
253     (patch by Ebrahim Mayat)
254 schoenebeck 697
255 persson 696 * Gigasampler format engine:
256 schoenebeck 738 - extensive synthesis optimization
257     (reimplementation of EGs and LFO(s), removed synthesis parameter
258     prerendering and the synthesis parameter matrix in general, splitting
259     each audio fragment into subfragments now where each subfragment uses
260 persson 830 constant pitch and filter coefficients. The volume coefficient is
261     linearly interpolated inside a subfragment, unless
262     --disable-interpolate-volume is set.)
263 persson 696 - fine tuning of the EG modulation parameters
264 persson 729 - improved filter cutoff calculation by adding support for the
265     following gig parameters: Cutoff freq (used when no cutoff
266     controller is defined), Control invert, Minimum cutoff, Velocity
267 persson 791 curve and Velocity range. The keyboard tracking now scales
268     cutoff frequency instead of resonance.
269 persson 877 - added support for gig parameter Resonance.
270 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
271 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
272     which can be overridden with --enable-global-attenuation
273 persson 783 - EG fixes: made the length of "attack hold" stage more
274     accurate. Release stage can now start before attack stage
275 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
276     time now has a minimal value to prevent clicks.
277 persson 799 - fixed pitch changes larger than one octave
278 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
279     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
280     all modes can be altered via standard GM messages, that is CC5 for
281     altering portamento time, CC65 for enabling / disabling portamento
282     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
283 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
284     parameter) and crossfade
285 persson 831 - added support for the "attenuation controller threshold" gig
286     parameter
287 persson 832 - added smoothing of volume changes caused by control change
288     messages
289 persson 865 - sample loop parameters are now taken from the DimensionRegion
290     instead of the wave chunk
291     - fixed keyswitching for v3 gigs with a number of keyswitch splits
292     not equal to a power of two
293 persson 877 - reimplementation of the filter algorithm. The new filter is more
294     accurate and supports all gig filter types, including bandreject
295     and lowpass turbo.
296 persson 903 - real support for 24 bit samples - samples are not truncated to
297     16 bits anymore
298     - support for aftertouch (channel pressure, not polyphonic
299     aftertouch)
300 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
301     amplifying from 0)
302 persson 696
303 schoenebeck 711 * LSCP server:
304     - fixed application exit on broken pipe error (fixes bug #20)
305 iliev 793 - fixed the notification messages delay due to lack of
306     network activity (fixes bug #26)
307 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
308     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
309 schoenebeck 711
310 schoenebeck 838 * audio driver:
311     - added aRts audio output driver (by no means RT safe)
312    
313 schoenebeck 775 * MIDI driver:
314     - fixed legacy sysex code which caused dispatching of MIDI SysEx
315     messages several times instead of once
316 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
317     for events (i.e. for offline rendering based MIDI drivers)
318 persson 922 - added checks for bad MIDI data
319 schoenebeck 775
320 schoenebeck 900 * linuxsampler application:
321     - show available sampler engine types on startup
322    
323 schoenebeck 705 * general changes:
324     - support for muting sampler channels and solo mode of the same, two new
325     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
326     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
327     introduced for this, the behavior is the same like on a mixer console
328 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
329     --enable-process-muted-channels which can be used to enable the
330     processing of muted channels.
331 iliev 777 - support for sostenuto pedal
332 iliev 779 - support for monitoring the total number of active voices
333 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
334     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
335 persson 835 - fixed some memory management errors
336 persson 841 - fixed some concurrency problems that could lead to crashes when
337     LSCP commands were executed
338 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
339     sampler channel (fixes bug #36)
340 schoenebeck 705
341 schoenebeck 692 Version 0.3.3 (15 July 2005)
342 schoenebeck 686
343     * packaging changes:
344     - fixed compilation with gcc 4.0
345    
346 schoenebeck 687 * Gigasampler format engine:
347     - LFO preprocessing was performed even though the respective LFO was
348     disabled by the instrument patch (minor efficiency fix)
349 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
350     for volume ramp downs in the same fragment (needed for current voice
351     stealing implementation) then simply inform the user with a warning
352     about possible click sounds and reduce the volume ramp down
353     appropriately instead of cancelling the audio device connection
354 schoenebeck 687
355 schoenebeck 677 Version 0.3.2 (24 June 2005)
356 schoenebeck 609
357     * packaging changes:
358     - updated autotools build files to compile on OS X
359     (conditional compilation of CoreMIDI and MidiShare drivers)
360 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
361     './configure --disable-asm' (definitely not recommended)
362 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
363     - require automake (>= 1.5) for 'make -f Makefile.cvs'
364     (due to 'dist-bzip2' automake option)
365 schoenebeck 649
366     * Gigasampler format engine:
367     - support for the gig parameters for "release velocity response" curves
368     - fine tuning of the EGADSR envelope
369     - volume of release triggered samples now depends on note-on velocity,
370     note length and gig parameter "release trigger decay" instead of
371     note-off velocity.
372 schoenebeck 663 - revised voice stealing
373     (fixes crash and endless loop caused by voice stealing)
374 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
375 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
376     instead of when the respective voice is actually launched
377     (fixes undefined behavior if stolen voices belonged to a key group -
378     this case was followed by a "killed voice survived" error message)
379 schoenebeck 669 - fixed minor issue with null/silence samples
380     (those stole voices even though they don't need a voice at all which
381     resulted in "voice stealing didn't work out" messages)
382 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
383     instrument or audio output device change
384 schoenebeck 654
385 schoenebeck 620 * LSCP server:
386 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
387 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
388 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
389 schoenebeck 609
390 schoenebeck 668 * linuxsampler application:
391     - added command line parameters --lscp-addr and --lscp-port to override
392     default IP address and port of LSCP server
393    
394 schoenebeck 579 Version 0.3.1 (24 May 2005)
395    
396     * initial release
