File size: 19377 byte(s)
* removed the nonsense audio channel constraint (which was hard coded to
  max. 100 audio channels) for most audio drivers

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