File size: 18469 byte(s)
* LSCP: allow naughty liblscp to send non-string device parameters
  within apostrophes as well

1 schoenebeck 1454 Version CVS HEAD (?)
2    
3     * packaging changes:
4     - added autoconf checks for pthread library
5     - added autoconf check for pthread bug found on certain NPTL-enabled
6     glibc versions (see Gentoo bug report #194076)
7    
8 persson 1455 * general changes:
9     - bugfix: the thread used by an editor plugin didn't die when the
10     editor closed
11 senoner 1479 - bugfix: Ringbuffer.h:
12     fill_write_space_with_null() did not zero out all the space
13     operator--() did not apply size_mask after decrementing the read_ptr
14 schoenebeck 1495 DEFAULT_WRAP_ELEMENTS set to 0 in order to avoid problems with
15 senoner 1479 the _NonVolatileReader functions.
16 senoner 1485 - bugfix: Stream.h: added a missing divide by BytesPerSample in GetWriteSpace()
17     since this function is currently only used in the stream's
18     qsort() compare function, it didn't trigger any bugs
19     Resampler.h, Synthesizer.h:
20     cubic interpolation now works in 24bit mode too
21     faster method to read 24bit words on little endian machines (x86):
22 schoenebeck 1495 replaced 3 byte reads + shifts with a 1 unaligned 32bit read and shift
23 persson 1455
24 senoner 1485 * MIDI driver:
25 schoenebeck 1495 - added MME Windows MIDI driver
26 senoner 1485
27 schoenebeck 1471 * LSCP server:
28     - added support for Windows style path / filenames, however with
29     forward slash path separators instead of backslash
30     (i.e. "C:/foo/bar.gig")
31 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
32     apostrophes as well
33 schoenebeck 1471
34 schoenebeck 1424 Version 0.5.0 (15 October 2007)
35 schoenebeck 947
36 schoenebeck 1065 * packaging changes:
37 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
38     API header files anymore
39 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
40     the Doxygen API documentation (explicitly listed in Doxyfile.in)
41 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
42     capable to execute our autoconf environment, thus no need anymore
43     to maintain the compile time configuration file (osx/version.h) for
44     OSX manually (patch by Toshi Nagata)
45 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
46     parameters
47 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
48     C++ API header files, all implementation internal global definitions
49     are now in global_private.h
50     - atomic.h is not exposed to the C++ API anymore
51     - no need to include config.h anymore for using LS's API header files
52     - fixed warnings in API doc generation
53 schoenebeck 1065
54 schoenebeck 947 * general changes:
55     - replaced the old, confusing MIDI program change mechanism by a
56     flexible MIDI instrument mapper which allows to map arbitrary
57 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
58 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
59     loaded on the respective channel when such MIDI program change
60     messages arrive, beside that, each entry allows to define a life-time
61     strategy for the instrument, so the user can define whether the
62     instrument should i.e. be permanently loaded (to be able to switch
63     quickly among sounds) or i.e. loaded just on demand when the
64     respective program change arrives (to safe RAM space), as well as a
65     global volume factor for each entry, so the user can adjust the volume
66     dynamic of his mapped instrument collection without having to modify
67 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
68     MIDI instrument maps and assign each sampler channel individually
69     a certain map, so that i.e. separation of normal instruments and
70     drumkits is possible
71 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
72     MIDI instrument maps, MIDI instruments, FX sends, global volume.
73 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
74     due to a constant size RingBuffer FIFO which is now replaced by a
75     dynamic (unlimited) size std::list FIFO
76 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
77     output channels for being processed by external effect processors
78     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
79     controllers
80 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
81 iliev 1130 - Implemented new, improved notification system
82 schoenebeck 1149 - fixed compilation errors regarding OSX
83     (patch by Toshi Nagata)
84 iliev 1161 - implemented instruments database
85 iliev 1345 - added support for escape sequences to the instruments database
86 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
87     within the sampler's process (by using instrument editor plugins),
88     you'll notice the new "Registered instrument editors:" message on
89 schoenebeck 1407 startup, added a new LSCP command:
90     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
91 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
92     given sampler channel, the plugin path can be overridden at compile
93     time with ./configure --enable-plugin-dir=/some/dir
94 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
95     in the sampler's process to safely edit instruments while playing
96     without a crash (hopefully) by either suspending single regions
97     wherever possible or if unavoidable whole engine(s)
98 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
99     policy and priority on thread level, set a minimum stack size for
100     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
101     threads simply inherited properties of starting thread instead of
102     setting their own policy and priority
103 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
104     main process did not wait for the stack trace process to finish
105     its output
106 persson 1248 - fixed some minor memory leaks
107 schoenebeck 1259 - reenabled assembly features support, at the moment only for
108     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
109 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
110     register, to avoid relocations in the text segment at runtime)
111 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
112 schoenebeck 947
113     * MIDI driver:
114     - dispatch bank select (MSB and LSB) messages
115    
116 schoenebeck 1049 * audio driver:
117     - the ALSA audio output driver parameters now reflect the correct
118     parameter value ranges for the respective selected sound card
119     (patch by Till Wimmer, a bit fixed and extended)
120    
121 persson 951 * Gigasampler format engine:
122     - if a filter is used and EG2 finishes before EG1, let the voice
123     die when EG2 has finished (this fixes a problem with clicks and
124     voice starvation for some gigs)
125 persson 1038 - playback is no longer disabled during instrument loading
126     - all notes playing on a channel that changes its instrument keep
127     playing with the old instrument until they get a note off
128     command
129 persson 1039 - EG fix: a release value of zero could cause noises or crash
130 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
131 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
132     above max sustain level, which means that there is a decay phase
133     even if sustain is 100%
134 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
135     noises or crashes
136 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
137 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
138     supplied to the configure script (fixes #46)
139 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
140     instead of a fix value
141 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
142     127 (solo mode) only kill voices if the respective mode really
143     changed
144 persson 951
145 schoenebeck 1244 * LSCP server:
146     - fixed compile time error for old Bison versions
147     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
148 schoenebeck 1245 - parser now supports extended ASCII character set
149     (up to ASCII code 255, i.e. includes now umlauts and accents)
150     - filename arguments in LSCP commands now allow to use escape
151     sequences, that is directly literal as one of: \', \", \\, \n, \r,
152     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
153     code value like \xf2) (fixes bug #24)
154 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
155     least one of their text-based parameters (i.e. name, description):
156     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
157     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
158     "SET DB_INSTRUMENT_DIRECTORY NAME",
159     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
160     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
161     "FIND DB_INSTRUMENT_DIRECTORIES"
162 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
163     occured, the unexpected character and the actually expected, possible
164     character(s), the latter only if less than 5 possibilities)
165 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
166     settings
167 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
168     of strings were treated as being one string containing commas
169     (fixes #57)
170 schoenebeck 1244
171 iliev 959 * Bug fixes:
172     - fixed crash occurring on certain LSCP scripts (Bug 39)
173 persson 1038 - another thread safety fix for lscp "load engine" and "set
174     channel audio output device"
175 iliev 1283 - fixed a crash which occurs when reassigning the same engine
176     on a sampler channel with connected MIDI device
177 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
178     device connected to a sampler channel to number less then or equal
179     to the index of the port to which the sampler channel is connected.
180 iliev 1296 - The previous bindings were not been disconnected when altering
181     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
182     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
183 iliev 1297 - The active stream/voice count statistic was incorrect.
184 iliev 1298 - notification events were not been sent for some sampler
185     channel changes
186 iliev 1305 - added default min and max values to restrict the number of allowed
187     audio output channels and MIDI input ports
188 iliev 1306 - the connection to the PCM interface is now closed when destroying
189     an audio output device
190 schoenebeck 1332 - files with slash in their path or filename could not be loaded
191 iliev 959
192 schoenebeck 1221 * test cases:
193     - updated and fixed (haven't been touched in a while)
194    
195 schoenebeck 937 Version 0.4.0 (24 November 2006)
196 persson 696
197 schoenebeck 697 * packaging changes:
198 capela 868 - changed deprecated copyright attribute to license; added ldconfig
199     to post-(un)install steps; added devel package for liblinuxsampler;
200     to linuxsampler.spec (RPM)
201 schoenebeck 697 - install necessary development header files for allowing 3rd party
202     applications to link against liblinuxsampler
203     - liblinuxsampler's API documentation can be generated with 'make docs'
204     (Doxygen required)
205 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
206     implementation (currently either an integer math solution or a
207     di-harmonic approximation), automatic detection can be overriden
208     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
209     configure script argument though (mandatory for cross-compilation)
210 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
211     provided some on his own (as CXXFLAGS)
212 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
213     messages
214 schoenebeck 852 - added compile time options to allow disabling the various audio and
215     MIDI drivers
216 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
217     (patch by Ebrahim Mayat)
218 schoenebeck 697
219 persson 696 * Gigasampler format engine:
220 schoenebeck 738 - extensive synthesis optimization
221     (reimplementation of EGs and LFO(s), removed synthesis parameter
222     prerendering and the synthesis parameter matrix in general, splitting
223     each audio fragment into subfragments now where each subfragment uses
224 persson 830 constant pitch and filter coefficients. The volume coefficient is
225     linearly interpolated inside a subfragment, unless
226     --disable-interpolate-volume is set.)
227 persson 696 - fine tuning of the EG modulation parameters
228 persson 729 - improved filter cutoff calculation by adding support for the
229     following gig parameters: Cutoff freq (used when no cutoff
230     controller is defined), Control invert, Minimum cutoff, Velocity
231 persson 791 curve and Velocity range. The keyboard tracking now scales
232     cutoff frequency instead of resonance.
233 persson 877 - added support for gig parameter Resonance.
234 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
235 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
236     which can be overridden with --enable-global-attenuation
237 persson 783 - EG fixes: made the length of "attack hold" stage more
238     accurate. Release stage can now start before attack stage
239 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
240     time now has a minimal value to prevent clicks.
241 persson 799 - fixed pitch changes larger than one octave
242 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
243     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
244     all modes can be altered via standard GM messages, that is CC5 for
245     altering portamento time, CC65 for enabling / disabling portamento
246     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
247 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
248     parameter) and crossfade
249 persson 831 - added support for the "attenuation controller threshold" gig
250     parameter
251 persson 832 - added smoothing of volume changes caused by control change
252     messages
253 persson 865 - sample loop parameters are now taken from the DimensionRegion
254     instead of the wave chunk
255     - fixed keyswitching for v3 gigs with a number of keyswitch splits
256     not equal to a power of two
257 persson 877 - reimplementation of the filter algorithm. The new filter is more
258     accurate and supports all gig filter types, including bandreject
259     and lowpass turbo.
260 persson 903 - real support for 24 bit samples - samples are not truncated to
261     16 bits anymore
262     - support for aftertouch (channel pressure, not polyphonic
263     aftertouch)
264 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
265     amplifying from 0)
266 persson 696
267 schoenebeck 711 * LSCP server:
268     - fixed application exit on broken pipe error (fixes bug #20)
269 iliev 793 - fixed the notification messages delay due to lack of
270     network activity (fixes bug #26)
271 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
272     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
273 schoenebeck 711
274 schoenebeck 838 * audio driver:
275     - added aRts audio output driver (by no means RT safe)
276    
277 schoenebeck 775 * MIDI driver:
278     - fixed legacy sysex code which caused dispatching of MIDI SysEx
279     messages several times instead of once
280 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
281     for events (i.e. for offline rendering based MIDI drivers)
282 persson 922 - added checks for bad MIDI data
283 schoenebeck 775
284 schoenebeck 900 * linuxsampler application:
285     - show available sampler engine types on startup
286    
287 schoenebeck 705 * general changes:
288     - support for muting sampler channels and solo mode of the same, two new
289     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
290     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
291     introduced for this, the behavior is the same like on a mixer console
292 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
293     --enable-process-muted-channels which can be used to enable the
294     processing of muted channels.
295 iliev 777 - support for sostenuto pedal
296 iliev 779 - support for monitoring the total number of active voices
297 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
298     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
299 persson 835 - fixed some memory management errors
300 persson 841 - fixed some concurrency problems that could lead to crashes when
301     LSCP commands were executed
302 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
303     sampler channel (fixes bug #36)
304 schoenebeck 705
305 schoenebeck 692 Version 0.3.3 (15 July 2005)
306 schoenebeck 686
307     * packaging changes:
308     - fixed compilation with gcc 4.0
309    
310 schoenebeck 687 * Gigasampler format engine:
311     - LFO preprocessing was performed even though the respective LFO was
312     disabled by the instrument patch (minor efficiency fix)
313 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
314     for volume ramp downs in the same fragment (needed for current voice
315     stealing implementation) then simply inform the user with a warning
316     about possible click sounds and reduce the volume ramp down
317     appropriately instead of cancelling the audio device connection
318 schoenebeck 687
319 schoenebeck 677 Version 0.3.2 (24 June 2005)
320 schoenebeck 609
321     * packaging changes:
322     - updated autotools build files to compile on OS X
323     (conditional compilation of CoreMIDI and MidiShare drivers)
324 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
325     './configure --disable-asm' (definitely not recommended)
326 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
327     - require automake (>= 1.5) for 'make -f Makefile.cvs'
328     (due to 'dist-bzip2' automake option)
329 schoenebeck 649
330     * Gigasampler format engine:
331     - support for the gig parameters for "release velocity response" curves
332     - fine tuning of the EGADSR envelope
333     - volume of release triggered samples now depends on note-on velocity,
334     note length and gig parameter "release trigger decay" instead of
335     note-off velocity.
336 schoenebeck 663 - revised voice stealing
337     (fixes crash and endless loop caused by voice stealing)
338 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
339 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
340     instead of when the respective voice is actually launched
341     (fixes undefined behavior if stolen voices belonged to a key group -
342     this case was followed by a "killed voice survived" error message)
343 schoenebeck 669 - fixed minor issue with null/silence samples
344     (those stole voices even though they don't need a voice at all which
345     resulted in "voice stealing didn't work out" messages)
346 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
347     instrument or audio output device change
348 schoenebeck 654
349 schoenebeck 620 * LSCP server:
350 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
351 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
352 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
353 schoenebeck 609
354 schoenebeck 668 * linuxsampler application:
355     - added command line parameters --lscp-addr and --lscp-port to override
356     default IP address and port of LSCP server
357    
358 schoenebeck 579 Version 0.3.1 (24 May 2005)
359    
360     * initial release
