Sun Nov 25 17:47:46 2007 UTC (16 years, 4 months ago) by schoenebeck
File size: 18939 byte(s)
* LSCP: added new LSCP commands: "GET FILE INSTRUMENTS <file>",
  "LIST FILE INSTRUMENTS <file>" and
  "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
  about an arbitrary instrument file on the system where the sampler is
  running on (LSCP specs yet to be updated!)
* bumped version to 0.5.0.1cvs
* bumped LSCP compliance to LSCP version 1.3

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 senoner 1502 - added autoconf checks for MS Windows
8 schoenebeck 1454
9 persson 1455 * general changes:
10     - bugfix: the thread used by an editor plugin didn't die when the
11     editor closed
12 senoner 1479 - bugfix: Ringbuffer.h:
13     fill_write_space_with_null() did not zero out all the space
14     operator--() did not apply size_mask after decrementing the read_ptr
15 schoenebeck 1495 DEFAULT_WRAP_ELEMENTS set to 0 in order to avoid problems with
16 senoner 1479 the _NonVolatileReader functions.
17 senoner 1485 - bugfix: Stream.h: added a missing divide by BytesPerSample in GetWriteSpace()
18     since this function is currently only used in the stream's
19     qsort() compare function, it didn't trigger any bugs
20     Resampler.h, Synthesizer.h:
21     cubic interpolation now works in 24bit mode too
22     faster method to read 24bit words on little endian machines (x86):
23 schoenebeck 1495 replaced 3 byte reads + shifts with a 1 unaligned 32bit read and shift
24 senoner 1502 Experimental support for MS Windows (MIDI input via MME, AUDIO output via ASIO)
25 persson 1455
26 senoner 1500 * AUDIO driver:
27     - added Windows ASIO low latency audio driver
28    
29 senoner 1485 * MIDI driver:
30 schoenebeck 1495 - added MME Windows MIDI driver
31 senoner 1485
32 schoenebeck 1471 * LSCP server:
33     - added support for Windows style path / filenames, however with
34     forward slash path separators instead of backslash
35     (i.e. "C:/foo/bar.gig")
36 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
37     apostrophes as well
38 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
39     "LIST FILE INSTRUMENTS <file>" and
40     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
41     about an arbitrary instrument file on the system where the sampler is
42     running on
43 schoenebeck 1471
44 schoenebeck 1424 Version 0.5.0 (15 October 2007)
45 schoenebeck 947
46 schoenebeck 1065 * packaging changes:
47 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
48     API header files anymore
49 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
50     the Doxygen API documentation (explicitly listed in Doxyfile.in)
51 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
52     capable to execute our autoconf environment, thus no need anymore
53     to maintain the compile time configuration file (osx/version.h) for
54     OSX manually (patch by Toshi Nagata)
55 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
56     parameters
57 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
58     C++ API header files, all implementation internal global definitions
59     are now in global_private.h
60     - atomic.h is not exposed to the C++ API anymore
61     - no need to include config.h anymore for using LS's API header files
62     - fixed warnings in API doc generation
63 schoenebeck 1065
64 schoenebeck 947 * general changes:
65     - replaced the old, confusing MIDI program change mechanism by a
66     flexible MIDI instrument mapper which allows to map arbitrary
67 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
68 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
69     loaded on the respective channel when such MIDI program change
70     messages arrive, beside that, each entry allows to define a life-time
71     strategy for the instrument, so the user can define whether the
72     instrument should i.e. be permanently loaded (to be able to switch
73     quickly among sounds) or i.e. loaded just on demand when the
74     respective program change arrives (to safe RAM space), as well as a
75     global volume factor for each entry, so the user can adjust the volume
76     dynamic of his mapped instrument collection without having to modify
77 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
78     MIDI instrument maps and assign each sampler channel individually
79     a certain map, so that i.e. separation of normal instruments and
80     drumkits is possible
81 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
82     MIDI instrument maps, MIDI instruments, FX sends, global volume.
83 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
84     due to a constant size RingBuffer FIFO which is now replaced by a
85     dynamic (unlimited) size std::list FIFO
86 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
87     output channels for being processed by external effect processors
88     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
89     controllers
90 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
91 iliev 1130 - Implemented new, improved notification system
92 schoenebeck 1149 - fixed compilation errors regarding OSX
93     (patch by Toshi Nagata)
94 iliev 1161 - implemented instruments database
95 iliev 1345 - added support for escape sequences to the instruments database
96 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
97     within the sampler's process (by using instrument editor plugins),
98     you'll notice the new "Registered instrument editors:" message on
99 schoenebeck 1407 startup, added a new LSCP command:
100     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
101 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
102     given sampler channel, the plugin path can be overridden at compile
103     time with ./configure --enable-plugin-dir=/some/dir
104 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
105     in the sampler's process to safely edit instruments while playing
106     without a crash (hopefully) by either suspending single regions
107     wherever possible or if unavoidable whole engine(s)
108 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
109     policy and priority on thread level, set a minimum stack size for
110     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
111     threads simply inherited properties of starting thread instead of
112     setting their own policy and priority
113 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
114     main process did not wait for the stack trace process to finish
115     its output
116 persson 1248 - fixed some minor memory leaks
117 schoenebeck 1259 - reenabled assembly features support, at the moment only for
118     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
119 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
120     register, to avoid relocations in the text segment at runtime)
121 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
122 schoenebeck 947
123     * MIDI driver:
124     - dispatch bank select (MSB and LSB) messages
125    
126 schoenebeck 1049 * audio driver:
127     - the ALSA audio output driver parameters now reflect the correct
128     parameter value ranges for the respective selected sound card
129     (patch by Till Wimmer, a bit fixed and extended)
130    
131 persson 951 * Gigasampler format engine:
132     - if a filter is used and EG2 finishes before EG1, let the voice
133     die when EG2 has finished (this fixes a problem with clicks and
134     voice starvation for some gigs)
135 persson 1038 - playback is no longer disabled during instrument loading
136     - all notes playing on a channel that changes its instrument keep
137     playing with the old instrument until they get a note off
138     command
139 persson 1039 - EG fix: a release value of zero could cause noises or crash
140 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
141 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
142     above max sustain level, which means that there is a decay phase
143     even if sustain is 100%
144 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
145     noises or crashes
146 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
147 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
148     supplied to the configure script (fixes #46)
149 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
150     instead of a fix value
151 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
152     127 (solo mode) only kill voices if the respective mode really
153     changed
154 persson 951
155 schoenebeck 1244 * LSCP server:
156     - fixed compile time error for old Bison versions
157     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
158 schoenebeck 1245 - parser now supports extended ASCII character set
159     (up to ASCII code 255, i.e. includes now umlauts and accents)
160     - filename arguments in LSCP commands now allow to use escape
161     sequences, that is directly literal as one of: \', \", \\, \n, \r,
162     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
163     code value like \xf2) (fixes bug #24)
164 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
165     least one of their text-based parameters (i.e. name, description):
166     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
167     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
168     "SET DB_INSTRUMENT_DIRECTORY NAME",
169     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
170     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
171     "FIND DB_INSTRUMENT_DIRECTORIES"
172 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
173     occured, the unexpected character and the actually expected, possible
174     character(s), the latter only if less than 5 possibilities)
175 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
176     settings
177 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
178     of strings were treated as being one string containing commas
179     (fixes #57)
180 schoenebeck 1244
181 iliev 959 * Bug fixes:
182     - fixed crash occurring on certain LSCP scripts (Bug 39)
183 persson 1038 - another thread safety fix for lscp "load engine" and "set
184     channel audio output device"
185 iliev 1283 - fixed a crash which occurs when reassigning the same engine
186     on a sampler channel with connected MIDI device
187 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
188     device connected to a sampler channel to number less then or equal
189     to the index of the port to which the sampler channel is connected.
190 iliev 1296 - The previous bindings were not been disconnected when altering
191     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
192     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
193 iliev 1297 - The active stream/voice count statistic was incorrect.
194 iliev 1298 - notification events were not been sent for some sampler
195     channel changes
196 iliev 1305 - added default min and max values to restrict the number of allowed
197     audio output channels and MIDI input ports
198 iliev 1306 - the connection to the PCM interface is now closed when destroying
199     an audio output device
200 schoenebeck 1332 - files with slash in their path or filename could not be loaded
201 iliev 959
202 schoenebeck 1221 * test cases:
203     - updated and fixed (haven't been touched in a while)
204    
205 schoenebeck 937 Version 0.4.0 (24 November 2006)
206 persson 696
207 schoenebeck 697 * packaging changes:
208 capela 868 - changed deprecated copyright attribute to license; added ldconfig
209     to post-(un)install steps; added devel package for liblinuxsampler;
210     to linuxsampler.spec (RPM)
211 schoenebeck 697 - install necessary development header files for allowing 3rd party
212     applications to link against liblinuxsampler
213     - liblinuxsampler's API documentation can be generated with 'make docs'
214     (Doxygen required)
215 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
216     implementation (currently either an integer math solution or a
217     di-harmonic approximation), automatic detection can be overriden
218     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
219     configure script argument though (mandatory for cross-compilation)
220 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
221     provided some on his own (as CXXFLAGS)
222 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
223     messages
224 schoenebeck 852 - added compile time options to allow disabling the various audio and
225     MIDI drivers
226 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
227     (patch by Ebrahim Mayat)
228 schoenebeck 697
229 persson 696 * Gigasampler format engine:
230 schoenebeck 738 - extensive synthesis optimization
231     (reimplementation of EGs and LFO(s), removed synthesis parameter
232     prerendering and the synthesis parameter matrix in general, splitting
233     each audio fragment into subfragments now where each subfragment uses
234 persson 830 constant pitch and filter coefficients. The volume coefficient is
235     linearly interpolated inside a subfragment, unless
236     --disable-interpolate-volume is set.)
237 persson 696 - fine tuning of the EG modulation parameters
238 persson 729 - improved filter cutoff calculation by adding support for the
239     following gig parameters: Cutoff freq (used when no cutoff
240     controller is defined), Control invert, Minimum cutoff, Velocity
241 persson 791 curve and Velocity range. The keyboard tracking now scales
242     cutoff frequency instead of resonance.
243 persson 877 - added support for gig parameter Resonance.
244 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
245 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
246     which can be overridden with --enable-global-attenuation
247 persson 783 - EG fixes: made the length of "attack hold" stage more
248     accurate. Release stage can now start before attack stage
249 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
250     time now has a minimal value to prevent clicks.
251 persson 799 - fixed pitch changes larger than one octave
252 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
253     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
254     all modes can be altered via standard GM messages, that is CC5 for
255     altering portamento time, CC65 for enabling / disabling portamento
256     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
257 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
258     parameter) and crossfade
259 persson 831 - added support for the "attenuation controller threshold" gig
260     parameter
261 persson 832 - added smoothing of volume changes caused by control change
262     messages
263 persson 865 - sample loop parameters are now taken from the DimensionRegion
264     instead of the wave chunk
265     - fixed keyswitching for v3 gigs with a number of keyswitch splits
266     not equal to a power of two
267 persson 877 - reimplementation of the filter algorithm. The new filter is more
268     accurate and supports all gig filter types, including bandreject
269     and lowpass turbo.
270 persson 903 - real support for 24 bit samples - samples are not truncated to
271     16 bits anymore
272     - support for aftertouch (channel pressure, not polyphonic
273     aftertouch)
274 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
275     amplifying from 0)
276 persson 696
277 schoenebeck 711 * LSCP server:
278     - fixed application exit on broken pipe error (fixes bug #20)
279 iliev 793 - fixed the notification messages delay due to lack of
280     network activity (fixes bug #26)
281 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
282     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
283 schoenebeck 711
284 schoenebeck 838 * audio driver:
285     - added aRts audio output driver (by no means RT safe)
286    
287 schoenebeck 775 * MIDI driver:
288     - fixed legacy sysex code which caused dispatching of MIDI SysEx
289     messages several times instead of once
290 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
291     for events (i.e. for offline rendering based MIDI drivers)
292 persson 922 - added checks for bad MIDI data
293 schoenebeck 775
294 schoenebeck 900 * linuxsampler application:
295     - show available sampler engine types on startup
296    
297 schoenebeck 705 * general changes:
298     - support for muting sampler channels and solo mode of the same, two new
299     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
300     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
301     introduced for this, the behavior is the same like on a mixer console
302 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
303     --enable-process-muted-channels which can be used to enable the
304     processing of muted channels.
305 iliev 777 - support for sostenuto pedal
306 iliev 779 - support for monitoring the total number of active voices
307 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
308     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
309 persson 835 - fixed some memory management errors
310 persson 841 - fixed some concurrency problems that could lead to crashes when
311     LSCP commands were executed
312 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
313     sampler channel (fixes bug #36)
314 schoenebeck 705
315 schoenebeck 692 Version 0.3.3 (15 July 2005)
316 schoenebeck 686
317     * packaging changes:
318     - fixed compilation with gcc 4.0
319    
320 schoenebeck 687 * Gigasampler format engine:
321     - LFO preprocessing was performed even though the respective LFO was
322     disabled by the instrument patch (minor efficiency fix)
323 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
324     for volume ramp downs in the same fragment (needed for current voice
325     stealing implementation) then simply inform the user with a warning
326     about possible click sounds and reduce the volume ramp down
327     appropriately instead of cancelling the audio device connection
328 schoenebeck 687
329 schoenebeck 677 Version 0.3.2 (24 June 2005)
330 schoenebeck 609
331     * packaging changes:
332     - updated autotools build files to compile on OS X
333     (conditional compilation of CoreMIDI and MidiShare drivers)
334 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
335     './configure --disable-asm' (definitely not recommended)
336 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
337     - require automake (>= 1.5) for 'make -f Makefile.cvs'
338     (due to 'dist-bzip2' automake option)
339 schoenebeck 649
340     * Gigasampler format engine:
341     - support for the gig parameters for "release velocity response" curves
342     - fine tuning of the EGADSR envelope
343     - volume of release triggered samples now depends on note-on velocity,
344     note length and gig parameter "release trigger decay" instead of
345     note-off velocity.
346 schoenebeck 663 - revised voice stealing
347     (fixes crash and endless loop caused by voice stealing)
348 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
349 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
350     instead of when the respective voice is actually launched
351     (fixes undefined behavior if stolen voices belonged to a key group -
352     this case was followed by a "killed voice survived" error message)
353 schoenebeck 669 - fixed minor issue with null/silence samples
354     (those stole voices even though they don't need a voice at all which
355     resulted in "voice stealing didn't work out" messages)
356 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
357     instrument or audio output device change
358 schoenebeck 654
359 schoenebeck 620 * LSCP server:
360 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
361 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
362 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
363 schoenebeck 609
364 schoenebeck 668 * linuxsampler application:
365     - added command line parameters --lscp-addr and --lscp-port to override
366     default IP address and port of LSCP server
367    
368 schoenebeck 579 Version 0.3.1 (24 May 2005)
369    
370     * initial release
