* bugfix: on some POSIX systems instrument editor plugins refused to
  load as we used a non-portable Linux specific struct field
  (fixes bug #70, patch by Ronald Baljeu)

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