Thu Nov 15 23:35:45 2007 UTC (16 years, 4 months ago) by senoner
File size: 18379 byte(s)
* win32 port, work in progress:
* added MME MIDI Input driver
* Resampler.h, gig/Synthesizer.h:
* changed return type of getSample() from int to int32_t

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