|
10 |
Version 1.0.0 (31 July 2009) |
11 |
|
12 |
* packaging changes: |
13 |
- autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly, |
14 |
causing e.g. the libgig test to fail when |
15 |
"./configure --disable-jack-driver" was used |
16 |
(patch by Alexis Ballier) |
17 |
- fixed compilation with gcc 4.3 |
18 |
- fixes for building on OS X (thanks to Ebrahim Mayat for testing) |
19 |
- fixed configure so it detects x86_64 (#107) |
20 |
- fixes for building with newer MinGW versions |
21 |
- fix for building with bison 2.4 (#111) |
22 |
- fixed building with libgig installed in a non-standard directory |
23 |
- minor fix in configure for mmsystem.h detection on MinGW |
24 |
- Windows: look for editor plugins and Fantasia using base |
25 |
directory of liblinuxsampler dll (look in the same directory and one |
26 |
directory above) |
27 |
- configure script fix: removed unconditional use of SSE |
28 |
- fixed building with sqlite installed in a non-standard directory |
29 |
- when cross-compiling, don't try to create instruments.db |
30 |
- fix for new mingw-w64 version, which has usleep |
31 |
|
32 |
* general changes: |
33 |
- bugfix: on some POSIX systems instrument editor plugins refused to |
34 |
load as we used a non-portable Linux specific struct field |
35 |
(fixes bug #70, patch by Ronald Baljeu) |
36 |
- fixed endless loop which occured when loading an instrument editor |
37 |
plugin DLL on Windows systems failed |
38 |
- fixed memory leaks that occurred when liblinuxsampler was unloaded |
39 |
- optimized the SynchronizedConfig class so it doesn't wait |
40 |
unnecessarily long after an update |
41 |
- added support for notifying instrument editors on note-on / note-off |
42 |
events (e.g. to highlight the pressed keys on the virtual keyboard |
43 |
of gigedit) |
44 |
- added support for triggering notes by instrument editors (see above) |
45 |
- be verbose on DLL load errors (on Linux) |
46 |
- fixed di-harmonic triangle LFO implementation (this LFO implementation |
47 |
is only used by very few systems, most pick the int math |
48 |
implementation, which is usually faster) |
49 |
- fixes for audio drivers with varying buffer sizes |
50 |
- experimental support for running LinuxSampler as a DSSI, LV2 and |
51 |
VST plugin |
52 |
- notification events for stream/voice count statistics are now sent |
53 |
only when there are actual changes |
54 |
- added memory ordering constraints to improve stability on |
55 |
multi-core and multi-cpu systems |
56 |
- maximum voices and disk streams can now be altered at runtime |
57 |
- fixed CPU feature detection on x86_64 (maybe fixes #108) |
58 |
- automatic stacktrace mechanism is now turned off by default and can |
59 |
be switched on by command line option "--stacktrace" (the automatic |
60 |
stacktrace mechanism seems to be broken on most systems at the moment) |
61 |
- C++ API method InstrumentManager::LaunchInstrumentEditor() now returns |
62 |
a pointer to the launched InstrumentEditor object |
63 |
- added optional 3rd party user data parameter for following |
64 |
liblinuxsampler C++ API methods: InstrumentEditor::Main(), |
65 |
InstrumentEditor::Launch(), |
66 |
InstrumentManager::LaunchInstrumentEditor() |
67 |
- theoretical fix: made SynchronizedConfig follow C++0x memory |
68 |
model more strictly |
69 |
- fixes for using large audio device buffers |
70 |
- Windows: add the installation directory to the DLL search path |
71 |
when loading an editor plugin (solves problems with VST and |
72 |
gigedit on systems with other GTK versions installed) |
73 |
|
74 |
* audio driver: |
75 |
- removed the nonsense audio channel constraint (which was hard coded to |
76 |
max. 100 audio channels) for most audio drivers |
77 |
- JACK audio driver did not offer a device parameter "SAMPLERATE" as |
78 |
opposed to the LSCP specs |
79 |
- bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK) |
80 |
reflected the wrong value |
81 |
- fixed a memory management bug in ASIO driver |
82 |
- Makefile fix: JACK_CFLAGS wasn't used |
83 |
- JACK: use jack_client_open instead of the deprecated |
84 |
jack_client_new |
85 |
- added (experimental) CoreAudio driver |
86 |
- applied old fixes to the ASIO driver that were included in the |
87 |
previous binary release but accidentally never committed to CVS |
88 |
(fixes #117) |
89 |
- fixes for ASIO on mingw-w64 (iasio wrapper is not needed on |
90 |
win64) |
91 |
- VST: added support for sample rate and buffer size changes |
92 |
- VST: close editor (Fantasia) when the VST is removed |
93 |
- VST: avoid opening Fantasia more than once for each VST instance |
94 |
- VST: export main function as "main" on Linux too (fix for |
95 |
energyXT) |
96 |
- VST: changed number of output channels from one stereo to 16 |
97 |
stereo |
98 |
- added channel routing, fxsends and midi maps to the settings |
99 |
stored in the plugin state |
100 |
- performance optimization of AudioChannel::MixTo() and |
101 |
AudioChannel::CopyTo() methods using GCC vector exensions |
102 |
(if available) |
103 |
- ASIO fixes: avoid initializing the device twice, avoid throwing |
104 |
exception when getting parameters from a disconnected device |
105 |
|
106 |
* MIDI driver: |
107 |
- added JACK MIDI driver |
108 |
- dispatch bank select as ordinary CC as well, the user might seriously |
109 |
want to (mis)use it for some purpose ("fixed" in all current MIDI |
110 |
input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME) |
111 |
- bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME, |
112 |
CoreMidi or AU |
113 |
- fixed mingw-w64 compilation error in MME driver |
114 |
- made program change handling in MIDI thread real-time safe by |
115 |
moving the logic to a non-RT thread |
116 |
- fixed minor memory leak in ALSA driver |
117 |
|
118 |
* instruments database: |
119 |
- avoid time consuming samples scanning when adding instruments |
120 |
to the instruments database |
121 |
- added support for handling lost files in the instruments database |
122 |
- Implemented option for adding instruments in separate directories |
123 |
in the instruments database |
124 |
(patch by Chris Cherrett & Andrew Williams, a bit adjusted) |
125 |
- work-around for missing fnmatch function on Windows to make |
126 |
instrument database compilable |
127 |
- added instrument database support on Windows |
128 |
works with both standalone mode and VST plugin. |
129 |
the instruments DB file is located in |
130 |
%USERPROFILE%\.linuxsampler\instruments.db which allows different |
131 |
databases for each windows user |
132 |
if no DB is present it automatically creates the .linuxsampler subdir |
133 |
and then creates an empty DB |
134 |
- fixed recursive import, which was broken on Windows |
135 |
|
136 |
* Gigasampler format engine: |
137 |
- fixed a memory leak that could happen when a channel was deleted |
138 |
while notes were playing |
139 |
- made it possible to load an instrument even if the audio thread |
140 |
isn't running |
141 |
- added partial support for the "Controller Triggered" MIDI rule, |
142 |
enough for piano gigs with pedal noise samples |
143 |
- minor fix: only mark FX sends as being modified if really the |
144 |
respective FX send MIDI controller was used |
145 |
- added support for GM global device volume SysEx message |
146 |
(can be selected at compile time to either apply globally to the |
147 |
whole sampler [default] or only to the sampler channels that are |
148 |
connected to the respective MIDI input port the SysEx message arrived |
149 |
on) |
150 |
- bugfix: notes triggered at position 0 in the audio buffer were |
151 |
sometimes wrongly killed in the same buffer, causing no sound to |
152 |
be played |
153 |
- added support for chromatic / drumkit mode Roland GS Sysex message |
154 |
which is usally used to switch a part between chromatic sounds and |
155 |
drumkit sounds (as opposed to their common default setting of MIDI |
156 |
part 10 being a drumkit part and all other ones chromatic parts), in |
157 |
LS however one can switch between the first 16 MIDI instrument maps |
158 |
defined for the sampler |
159 |
- made it possible to create multiple sample channels even if the |
160 |
audio thread isn't running |
161 |
- fixed crash when removing channel with active voices (#116) |
162 |
- bugfix: on sample reference changes (instrument editor), only |
163 |
un-cache the respective sample if it's really not used by any |
164 |
sampler engine anymore |
165 |
- re-cache samples in case they were changed by an instrument editor, |
166 |
e.g. when a sample was added while playing (#82) |
167 |
- fixed hanging notes which occured when note-off event had the exact |
168 |
same time stamp as the voice's note-on event and occured both in the |
169 |
same audio fragment cycle (fixes bug #112) |
170 |
- added support for the "fine tune" and "pitch bend range" |
171 |
instrument-level gig parameters |
172 |
- fixed minor artifacts in pitch bend handling |
173 |
- added support for GS Reset SysEx message |
174 |
- allow gig files to use unlimited downward pitch shifting |
175 |
- added a limit check for upward pitch shifting |
176 |
- bugfix: sometimes, when playing a note twice fast, the second |
177 |
note was silent |
178 |
- fixed crash happening when a pitch bend event arrived at the |
179 |
same time a new instrument was loading |
180 |
|
181 |
* LSCP server: |
182 |
- added new LSCP event "CHANNEL_MIDI" which can be used by frontends to |
183 |
react on MIDI data arriving on certain sampler channels (so far only |
184 |
Note-On and Note-Off events are sent via this LSCP event) |
185 |
- added new LSCP event "DEVICE_MIDI" which can be used by frontends to |
186 |
react on MIDI data arriving on certain MIDI input devices (so far only |
187 |
Note-On and Note-Off events are sent via this LSCP event) |
188 |
- added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and |
189 |
SET DB_INSTRUMENT FILE_PATH |
190 |
- added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by |
191 |
frontends to send MIDI messages to specific sampler channel |
192 |
- added two additional fields to GET FILE INSTRUMENT INFO command - |
193 |
KEY_BINDINGS and KEYSWITCH_BINDINGS |
194 |
- bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications |
195 |
was incorrect |
196 |
- Optimized the retrieval of the MIDI instrument mappings |
197 |
- added new LSCP command "SET VOICES" to globally alter the maximum |
198 |
amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will |
199 |
be triggered respectively |
200 |
- added new LSCP command "SET STREAMS" to globally alter the maximum |
201 |
amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS" |
202 |
which will be triggered respectively |
203 |
- bugfix: retry if "select" returns EINTR (this fixes a crash when |
204 |
a gigedit file dialog is opened) |
205 |
- close all connections when LSCPServer is deleted |
206 |
- hard close of all sockets on exit |
207 |
- bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME |
208 |
driver |
209 |
|
210 |
* Bug fixes: |
211 |
- fixed a crash which occurs when removing a sampler channel waiting |
212 |
to start instrument loading after another channel |
213 |
- fixed a crash which occurs when removing a sampler channel with |
214 |
instrument loading in progress (bug #113) |
215 |
- fixed termination caused by uncaught exception when adding MIDI |
216 |
instrument with PERSISTENT load mode |
217 |
- fixed possible iterator invalidations when resetting the sampler |
218 |
- fixed memory leaks when issuing the following LSCP commands: |
219 |
GET AUDIO_OUTPUT_DRIVER INFO |
220 |
GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO |
221 |
GET MIDI_INPUT_DRIVER INFO |
222 |
GET MIDI_INPUT_DRIVER_PARAMETER INFO |
223 |
- fixed possible compilation error when sqlite is not present |
224 |
- fixed orphaned pointers when setting maximum voices limit (bug #118) |
225 |
- fixed crash when changing the audio output device of a sampler |
226 |
channel with loaded instrument and start playing notes |
227 |
- fixed endless loop in Engine::SuspendAll() (bug #120) |
228 |
- fixed a low-level atomic load function that was broken on 64-bit |
229 |
PowerPC, which probably could cause crashes on that platform |
230 |
- fixed a memory management error which could cause a crash when a |
231 |
plugin was unloaded |
232 |
- bugfix: two private structs had the same name, which could cause |
233 |
problems if the linker chose the wrong constructor |
234 |
- fixed low-level ConditionServer usage bug that caused lockups on |
235 |
Windows |
236 |
|
237 |
|
238 |
Version 0.5.1 (6 December 2007) |
239 |
|
240 |
* packaging changes: |
241 |
- added autoconf checks for pthread library |
242 |
- added autoconf check for pthread bug found on certain NPTL-enabled |
243 |
glibc versions (see Gentoo bug report #194076) |
244 |
- added autoconf checks for MS Windows |
245 |
|
246 |
* general changes: |
247 |
- bugfix: the thread used by an editor plugin didn't die when the |
248 |
editor closed |
249 |
- bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero |
250 |
out all the space. operator--() did not apply size_mask after |
251 |
decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in |
252 |
order to avoid problems with the _NonVolatileReader functions. |
253 |
- bugfix: Stream.h: added a missing divide by BytesPerSample in |
254 |
GetWriteSpace(). Since this function is currently only used in |
255 |
the stream's qsort() compare function, it didn't trigger any |
256 |
bugs. |
257 |
- Resampler.h, Synthesizer.h: cubic interpolation now works in |
258 |
24bit mode too. Faster method to read 24bit words on little |
259 |
endian machines (x86): replaced 3 byte reads + shifts with a 1 |
260 |
unaligned 32bit read and shift |
261 |
- experimental support for MS Windows (MIDI input via MME, AUDIO |
262 |
output via ASIO) |
263 |
- made handling of SIGINT signal (Ctrl-C) a bit more robust |
264 |
- support for monitoring the total number of active disk streams |
265 |
(new LSCP commands: GET TOTAL_STREAM_COUNT, |
266 |
SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT) |
267 |
|
268 |
* AUDIO driver: |
269 |
- added Windows ASIO low latency audio driver |
270 |
|
271 |
* MIDI driver: |
272 |
- added MME Windows MIDI driver |
273 |
|
274 |
* LSCP server: |
275 |
- added support for Windows style path / filenames, however with |
276 |
forward slash path separators instead of backslash |
277 |
(i.e. "C:/foo/bar.gig") |
278 |
- allow naughty liblscp to send non-string device parameters within |
279 |
apostrophes as well |
280 |
- added new LSCP commands: "GET FILE INSTRUMENTS <file>", |
281 |
"LIST FILE INSTRUMENTS <file>" and |
282 |
"GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations |
283 |
about an arbitrary instrument file on the system where the sampler is |
284 |
running on |
285 |
|
286 |
Version 0.5.0 (15 October 2007) |
287 |
|
288 |
* packaging changes: |
289 |
- config.h is not going to be installed along with liblinuxsampler's |
290 |
API header files anymore |
291 |
- only the API relevant header (and source) files will be exported to |
292 |
the Doxygen API documentation (explicitly listed in Doxyfile.in) |
293 |
- added completely new XCode project files for Mac OSX which is now |
294 |
capable to execute our autoconf environment, thus no need anymore |
295 |
to maintain the compile time configuration file (osx/version.h) for |
296 |
OSX manually (patch by Toshi Nagata) |
297 |
- fixed buggy boolean --enable-foo / --disable-foo configure script |
298 |
parameters |
299 |
- global.h now only covers global definitions that are needed for the |
300 |
C++ API header files, all implementation internal global definitions |
301 |
are now in global_private.h |
302 |
- atomic.h is not exposed to the C++ API anymore |
303 |
- no need to include config.h anymore for using LS's API header files |
304 |
- fixed warnings in API doc generation |
305 |
|
306 |
* general changes: |
307 |
- replaced the old, confusing MIDI program change mechanism by a |
308 |
flexible MIDI instrument mapper which allows to map arbitrary |
309 |
(MIDI bank, MIDI program) pairs with arbitrary |
310 |
(engine type, instrument file, file index) triplets which will be |
311 |
loaded on the respective channel when such MIDI program change |
312 |
messages arrive, beside that, each entry allows to define a life-time |
313 |
strategy for the instrument, so the user can define whether the |
314 |
instrument should i.e. be permanently loaded (to be able to switch |
315 |
quickly among sounds) or i.e. loaded just on demand when the |
316 |
respective program change arrives (to safe RAM space), as well as a |
317 |
global volume factor for each entry, so the user can adjust the volume |
318 |
dynamic of his mapped instrument collection without having to modify |
319 |
the instrument files, also one can manage arbitrary amount of such |
320 |
MIDI instrument maps and assign each sampler channel individually |
321 |
a certain map, so that i.e. separation of normal instruments and |
322 |
drumkits is possible |
323 |
- new notification events for tracking changes to audio/MIDI devices, |
324 |
MIDI instrument maps, MIDI instruments, FX sends, global volume. |
325 |
- sampler was limited to load max. 200 instruments in the background |
326 |
due to a constant size RingBuffer FIFO which is now replaced by a |
327 |
dynamic (unlimited) size std::list FIFO |
328 |
- added FX sends, these allow to route audio signals to arbitrary audio |
329 |
output channels for being processed by external effect processors |
330 |
(i.e. jack-rack), the send levels are controllable via arbitrary MIDI |
331 |
controllers |
332 |
- global (sampler wide) volume can now be controlled at runtime |
333 |
- Implemented new, improved notification system |
334 |
- fixed compilation errors regarding OSX |
335 |
(patch by Toshi Nagata) |
336 |
- implemented instruments database |
337 |
- added support for escape sequences to the instruments database |
338 |
- added highly experimental support for on-the-fly instrument editing |
339 |
within the sampler's process (by using instrument editor plugins), |
340 |
you'll notice the new "Registered instrument editors:" message on |
341 |
startup, added a new LSCP command: |
342 |
"EDIT CHANNEL INSTRUMENT <sampler-channel>" |
343 |
to spawn a matching instrument editor for the instrument on the |
344 |
given sampler channel, the plugin path can be overridden at compile |
345 |
time with ./configure --enable-plugin-dir=/some/dir |
346 |
- added experimental code for synchronizing instrument editors hosted |
347 |
in the sampler's process to safely edit instruments while playing |
348 |
without a crash (hopefully) by either suspending single regions |
349 |
wherever possible or if unavoidable whole engine(s) |
350 |
- fixed several issues in fundamental "Thread" class: set scheduling |
351 |
policy and priority on thread level, set a minimum stack size for |
352 |
thread (TODO: a reasonable value yet to be tested), bugfix: non-RT |
353 |
threads simply inherited properties of starting thread instead of |
354 |
setting their own policy and priority |
355 |
- minor fix in our automatic stack trace mechanism on crashes, the |
356 |
main process did not wait for the stack trace process to finish |
357 |
its output |
358 |
- fixed some minor memory leaks |
359 |
- reenabled assembly features support, at the moment only for |
360 |
enabling a fast denormal FPU mode (x86 platforms supporting SSE2) |
361 |
- minor assembly fix in x86 features detection (don't use the PIC |
362 |
register, to avoid relocations in the text segment at runtime) |
363 |
- POSIX callback functions of Thread.h are hidden |
364 |
|
365 |
* MIDI driver: |
366 |
- dispatch bank select (MSB and LSB) messages |
367 |
|
368 |
* audio driver: |
369 |
- the ALSA audio output driver parameters now reflect the correct |
370 |
parameter value ranges for the respective selected sound card |
371 |
(patch by Till Wimmer, a bit fixed and extended) |
372 |
|
373 |
* Gigasampler format engine: |
374 |
- if a filter is used and EG2 finishes before EG1, let the voice |
375 |
die when EG2 has finished (this fixes a problem with clicks and |
376 |
voice starvation for some gigs) |
377 |
- playback is no longer disabled during instrument loading |
378 |
- all notes playing on a channel that changes its instrument keep |
379 |
playing with the old instrument until they get a note off |
380 |
command |
381 |
- EG fix: a release value of zero could cause noises or crash |
382 |
- handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB) |
383 |
- EG fine tuning: when attack is zero the EG starts at a level |
384 |
above max sustain level, which means that there is a decay phase |
385 |
even if sustain is 100% |
386 |
- more EG fixes: the level could sometimes go below zero and cause |
387 |
noises or crashes |
388 |
- minor fix of EGDecay (patch by Toshi Nagata) |
389 |
- fixed compiler error when --enable-override-filter-type was |
390 |
supplied to the configure script (fixes #46) |
391 |
- disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS |
392 |
instead of a fix value |
393 |
- behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode), |
394 |
127 (solo mode) only kill voices if the respective mode really |
395 |
changed |
396 |
|
397 |
* LSCP server: |
398 |
- fixed compile time error for old Bison versions |
399 |
(i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata) |
400 |
- parser now supports extended ASCII character set |
401 |
(up to ASCII code 255, i.e. includes now umlauts and accents) |
402 |
- filename arguments in LSCP commands now allow to use escape |
403 |
sequences, that is directly literal as one of: \', \", \\, \n, \r, |
404 |
\f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII |
405 |
code value like \xf2) (fixes bug #24) |
406 |
- the following LSCP commands now also support escape sequences for at |
407 |

414 |
- returns verbose syntax errors (line and column where syntax error |
415 |
occured, the unexpected character and the actually expected, possible |
416 |
character(s), the latter only if less than 5 possibilities) |
417 |
- made sure that LSCP syntax is not affected by gigedit locale |
418 |
settings |
419 |
- bugfix regarding strings parameter lists: all comma separated lists |
420 |
of strings were treated as being one string containing commas |
421 |
(fixes #57) |
422 |
|
423 |
* Bug fixes: |
424 |
- fixed crash occurring on certain LSCP scripts (Bug 39) |
425 |
- another thread safety fix for lscp "load engine" and "set |
426 |
channel audio output device" |
427 |
- fixed a crash which occurs when reassigning the same engine |
428 |
on a sampler channel with connected MIDI device |
429 |
- fixed a crash which occurs when changing the number of ports of a MIDI |
430 |
device connected to a sampler channel to number less then or equal |
431 |
to the index of the port to which the sampler channel is connected. |
432 |
- The previous bindings were not been disconnected when altering |
433 |
the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for |
434 |
unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE). |
435 |
- The active stream/voice count statistic was incorrect. |
436 |
- notification events were not been sent for some sampler |
437 |
channel changes |
438 |
- added default min and max values to restrict the number of allowed |
439 |
audio output channels and MIDI input ports |
440 |
- the connection to the PCM interface is now closed when destroying |
441 |
an audio output device |
442 |
- files with slash in their path or filename could not be loaded |
443 |
|
444 |
* test cases: |
445 |
- updated and fixed (haven't been touched in a while) |
446 |
|
447 |
Version 0.4.0 (24 November 2006) |
448 |
|
449 |
* packaging changes: |
450 |
- changed deprecated copyright attribute to license; added ldconfig |
451 |
to post-(un)install steps; added devel package for liblinuxsampler; |
452 |
to linuxsampler.spec (RPM) |
453 |
- install necessary development header files for allowing 3rd party |
454 |
applications to link against liblinuxsampler |
455 |
- liblinuxsampler's API documentation can be generated with 'make docs' |
456 |
(Doxygen required) |
457 |
- added benchmark to automatically detect the best triangle LFO |
458 |
implementation (currently either an integer math solution or a |
459 |
di-harmonic approximation), automatic detection can be overriden |
460 |
with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x |
461 |
configure script argument though (mandatory for cross-compilation) |
462 |
- do not automatically pick optimized gcc flags if the user already |
463 |
provided some on his own (as CXXFLAGS) |
464 |
- added compile time option to disable processing of All-Notes-Off MIDI |
465 |
messages |
466 |
- added compile time options to allow disabling the various audio and |
467 |
MIDI drivers |
468 |
- fixed automatic GCC CPU switch detection on PPC |
469 |
(patch by Ebrahim Mayat) |
470 |
|
471 |
* Gigasampler format engine: |
472 |
- extensive synthesis optimization |
473 |
(reimplementation of EGs and LFO(s), removed synthesis parameter |
474 |
prerendering and the synthesis parameter matrix in general, splitting |
475 |
each audio fragment into subfragments now where each subfragment uses |
476 |
constant pitch and filter coefficients. The volume coefficient is |
477 |
linearly interpolated inside a subfragment, unless |
478 |
--disable-interpolate-volume is set.) |
479 |
- fine tuning of the EG modulation parameters |
480 |
- improved filter cutoff calculation by adding support for the |
481 |
following gig parameters: Cutoff freq (used when no cutoff |
482 |
controller is defined), Control invert, Minimum cutoff, Velocity |
483 |
curve and Velocity range. The keyboard tracking now scales |
484 |
cutoff frequency instead of resonance. |
485 |
- added support for gig parameter Resonance. |
486 |
- fixed bug in sysex handling (patch by Juan Linietsky) |
487 |
- added global volume attenuation of -9 dB (0.35f) to prevent clipping |
488 |
which can be overridden with --enable-global-attenuation |
489 |
- EG fixes: made the length of "attack hold" stage more |
490 |
accurate. Release stage can now start before attack stage |
491 |
ends. Cancel release didn't work when sustain was zero. Attack |
492 |
time now has a minimal value to prevent clicks. |
493 |
- fixed pitch changes larger than one octave |
494 |
- fixed EG3 (pitch envelope) synthesis which was neutral all the time |
495 |
- implemented portamento mode and solo mode (a.k.a 'mono mode'): |
496 |
all modes can be altered via standard GM messages, that is CC5 for |
497 |
altering portamento time, CC65 for enabling / disabling portamento |
498 |
mode, CC126 for enabling solo mode and CC127 for disabling solo mode |
499 |
- fine tuning of the curves for volume (CC7), pan (CC10 and gig |
500 |
parameter) and crossfade |
501 |
- added support for the "attenuation controller threshold" gig |
502 |
parameter |
503 |
- added smoothing of volume changes caused by control change |
504 |
messages |
505 |
- sample loop parameters are now taken from the DimensionRegion |
506 |
instead of the wave chunk |
507 |
- fixed keyswitching for v3 gigs with a number of keyswitch splits |
508 |
not equal to a power of two |
509 |
- reimplementation of the filter algorithm. The new filter is more |
510 |
accurate and supports all gig filter types, including bandreject |
511 |
and lowpass turbo. |
512 |
- real support for 24 bit samples - samples are not truncated to |
513 |
16 bits anymore |
514 |
- support for aftertouch (channel pressure, not polyphonic |
515 |
aftertouch) |
516 |
- LFO1 behaviour fixed (dampening from max volume instead of |
517 |
amplifying from 0) |
518 |
|
519 |
* LSCP server: |
520 |
- fixed application exit on broken pipe error (fixes bug #20) |
521 |
- fixed the notification messages delay due to lack of |
522 |
network activity (fixes bug #26) |
523 |
- fixed parser bug which occured on space(s) within device parameters |
524 |
(e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'") |
525 |
|
526 |
* audio driver: |
527 |
- added aRts audio output driver (by no means RT safe) |
528 |
|
529 |
* MIDI driver: |
530 |
- fixed legacy sysex code which caused dispatching of MIDI SysEx |
531 |
messages several times instead of once |
532 |
- API extension for MIDI drivers which already supply exact time stamps |
533 |
for events (i.e. for offline rendering based MIDI drivers) |
534 |
- added checks for bad MIDI data |
535 |
|
536 |
* linuxsampler application: |
537 |
- show available sampler engine types on startup |
538 |
|
539 |
* general changes: |
540 |
- support for muting sampler channels and solo mode of the same, two new |
541 |
LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new |
542 |
fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were |
543 |
introduced for this, the behavior is the same like on a mixer console |
544 |
(patch by Grigor Iliev, a bit adjusted). Also added configure option |
545 |
--enable-process-muted-channels which can be used to enable the |
546 |
processing of muted channels. |
547 |
- support for sostenuto pedal |
548 |
- support for monitoring the total number of active voices |
549 |
(new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX, |
550 |
SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT) |
551 |
- fixed some memory management errors |
552 |
- fixed some concurrency problems that could lead to crashes when |
553 |
LSCP commands were executed |
554 |
- fixed crash when instrument loading failed previously on the same |
555 |
sampler channel (fixes bug #36) |
556 |
|
557 |
Version 0.3.3 (15 July 2005) |
558 |
|
559 |
* packaging changes: |
560 |
- fixed compilation with gcc 4.0 |
561 |
|
562 |
* Gigasampler format engine: |
563 |
- LFO preprocessing was performed even though the respective LFO was |
564 |
disabled by the instrument patch (minor efficiency fix) |
565 |
- if period time of chosen audio device is too small (< MIN_RELEASE_TIME) |
566 |
for volume ramp downs in the same fragment (needed for current voice |
567 |
stealing implementation) then simply inform the user with a warning |
568 |
about possible click sounds and reduce the volume ramp down |
569 |
appropriately instead of cancelling the audio device connection |
570 |
|
571 |
Version 0.3.2 (24 June 2005) |
572 |
|
573 |
* packaging changes: |
574 |
- updated autotools build files to compile on OS X |
575 |
(conditional compilation of CoreMIDI and MidiShare drivers) |
576 |
- hand-crafted assembly optimization code can be disabled with |
577 |
'./configure --disable-asm' (definitely not recommended) |
578 |
- fixed 'make dist' rule to include all necessary files |
579 |
- require automake (>= 1.5) for 'make -f Makefile.cvs' |
580 |
(due to 'dist-bzip2' automake option) |
581 |
|
582 |
* Gigasampler format engine: |
583 |
- support for the gig parameters for "release velocity response" curves |
584 |
- fine tuning of the EGADSR envelope |
585 |
- volume of release triggered samples now depends on note-on velocity, |
586 |
note length and gig parameter "release trigger decay" instead of |
587 |
note-off velocity. |
588 |
- revised voice stealing |
589 |
(fixes crash and endless loop caused by voice stealing) |
590 |
- don't reset scale tuning on instrument or audio output device change |
591 |
- handle key group conflicts right at the beginning of each fragment |
592 |
instead of when the respective voice is actually launched |
593 |
(fixes undefined behavior if stolen voices belonged to a key group - |
594 |
this case was followed by a "killed voice survived" error message) |
595 |
- fixed minor issue with null/silence samples |
596 |
(those stole voices even though they don't need a voice at all which |
597 |
resulted in "voice stealing didn't work out" messages) |
598 |
- don't reset volume, pan, pitch and MIDI controller values on |
599 |
instrument or audio output device change |
600 |
|
601 |
* LSCP server: |
602 |
- fixed some crashes (patch by Grigor Iliev, fixes #19) |
603 |
- fixed LSCP event "CHANNEL_INFO" notification |
604 |
(e.g. did not notify on volume changes or MIDI program change events) |
605 |
|
606 |
* linuxsampler application: |
607 |
- added command line parameters --lscp-addr and --lscp-port to override |
608 |
default IP address and port of LSCP server |
609 |
|
610 |
Version 0.3.1 (24 May 2005) |
611 |
|
612 |
* initial release |
