Version CVS HEAD (?) |
2 |
|
3 |
* General changes: |
4 |
- Refactoring: moved the independent code from |
5 |
the Gigasampler format engine to base classes |
6 |
|
7 |
* Gigasampler format engine: |
8 |
- implemented the "round robin keyboard" dimension |
9 |
- fixed round robin and random dimensions for cases when number of |
10 |
dimension zones is not a power of two |
11 |
- made round robin use a counter for each region instead of each |
12 |
key |
13 |
|
14 |
* SFZ format engine |
15 |
- Initial implementation (not usable yet) |
16 |
|
17 |
* SoundFont format engine |
18 |
- Initial implementation (not usable yet) |
19 |
|
20 |
* Host plugins: |
21 |
- AU bugfix: failed to destroy its audio/MIDI devices |
22 |
- Listen to all interfaces on Mac OS X (INADDR_ANY) |
23 |
- VST bugfix: If the host called resume() before and after |
24 |
changing sample rate or block size, the number of channels was |
25 |
incorrectly set to two. This caused silence in Cubase 5. |
26 |
|
27 |
* MIDI driver: |
28 |
- ALSA MIDI driver supports now "NAME" device parameter, for overriding |
29 |
the ALSA sequencer client name |
30 |
|
31 |
* LSCP server: |
32 |
- added support for sending MIDI CC messages via LSCP command |
33 |
"SEND CHANNEL MIDI_DATA CC <sampler-chan> <ctrl> <val>" |
34 |
|
35 |
* Bug fixes: |
36 |
- Fixed crash which may occur when MIDI key + transpose is out of range |
37 |
|
38 |
Version 1.0.0 (31 July 2009) |
39 |
|
40 |
* packaging changes: |
41 |
- autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly, |
42 |
causing e.g. the libgig test to fail when |
43 |
"./configure --disable-jack-driver" was used |
44 |
(patch by Alexis Ballier) |
45 |
- fixed compilation with gcc 4.3 |
46 |
- fixes for building on OS X (thanks to Ebrahim Mayat for testing) |
47 |
- fixed configure so it detects x86_64 (#107) |
48 |
- fixes for building with newer MinGW versions |
49 |
- fix for building with bison 2.4 (#111) |
50 |
- fixed building with libgig installed in a non-standard directory |
51 |
- minor fix in configure for mmsystem.h detection on MinGW |
52 |
- Windows: look for editor plugins and Fantasia using base |
53 |
directory of liblinuxsampler dll (look in the same directory and one |
54 |
directory above) |
55 |
- configure script fix: removed unconditional use of SSE |
56 |
- fixed building with sqlite installed in a non-standard directory |
57 |
- when cross-compiling, don't try to create instruments.db |
58 |
- fix for new mingw-w64 version, which has usleep |
59 |
|
60 |
* general changes: |
61 |
- bugfix: on some POSIX systems instrument editor plugins refused to |
62 |
load as we used a non-portable Linux specific struct field |
63 |
(fixes bug #70, patch by Ronald Baljeu) |
64 |
- fixed endless loop which occured when loading an instrument editor |
65 |
plugin DLL on Windows systems failed |
66 |
- fixed memory leaks that occurred when liblinuxsampler was unloaded |
67 |
- optimized the SynchronizedConfig class so it doesn't wait |
68 |
unnecessarily long after an update |
69 |
- added support for notifying instrument editors on note-on / note-off |
70 |
events (e.g. to highlight the pressed keys on the virtual keyboard |
71 |
of gigedit) |
72 |
- added support for triggering notes by instrument editors (see above) |
73 |
- be verbose on DLL load errors (on Linux) |
74 |
- fixed di-harmonic triangle LFO implementation (this LFO implementation |
75 |
is only used by very few systems, most pick the int math |
76 |
implementation, which is usually faster) |
77 |
- fixes for audio drivers with varying buffer sizes |
78 |
- experimental support for running LinuxSampler as a DSSI, LV2 and |
79 |
VST plugin |
80 |
- notification events for stream/voice count statistics are now sent |
81 |
only when there are actual changes |
82 |
- added memory ordering constraints to improve stability on |
83 |
multi-core and multi-cpu systems |
84 |
- maximum voices and disk streams can now be altered at runtime |
85 |
- fixed CPU feature detection on x86_64 (maybe fixes #108) |
86 |
- automatic stacktrace mechanism is now turned off by default and can |
87 |
be switched on by command line option "--stacktrace" (the automatic |
88 |
stacktrace mechanism seems to be broken on most systems at the moment) |
89 |
- C++ API method InstrumentManager::LaunchInstrumentEditor() now returns |
90 |
a pointer to the launched InstrumentEditor object |
91 |
- added optional 3rd party user data parameter for following |
92 |
liblinuxsampler C++ API methods: InstrumentEditor::Main(), |
93 |
InstrumentEditor::Launch(), |
94 |
InstrumentManager::LaunchInstrumentEditor() |
95 |
- theoretical fix: made SynchronizedConfig follow C++0x memory |
96 |
model more strictly |
97 |
- fixes for using large audio device buffers |
98 |
- Windows: add the installation directory to the DLL search path |
99 |
when loading an editor plugin (solves problems with VST and |
100 |
gigedit on systems with other GTK versions installed) |
101 |
|
102 |
* audio driver: |
103 |
- removed the nonsense audio channel constraint (which was hard coded to |
104 |
max. 100 audio channels) for most audio drivers |
105 |
- JACK audio driver did not offer a device parameter "SAMPLERATE" as |
106 |
opposed to the LSCP specs |
107 |
- bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK) |
108 |
reflected the wrong value |
109 |
- fixed a memory management bug in ASIO driver |
110 |
- Makefile fix: JACK_CFLAGS wasn't used |
111 |
- JACK: use jack_client_open instead of the deprecated |
112 |
jack_client_new |
113 |
- added (experimental) CoreAudio driver |
114 |
- applied old fixes to the ASIO driver that were included in the |
115 |
previous binary release but accidentally never committed to CVS |
116 |
(fixes #117) |
117 |
- fixes for ASIO on mingw-w64 (iasio wrapper is not needed on |
118 |
win64) |
119 |
- VST: added support for sample rate and buffer size changes |
120 |
- VST: close editor (Fantasia) when the VST is removed |
121 |
- VST: avoid opening Fantasia more than once for each VST instance |
122 |
- VST: export main function as "main" on Linux too (fix for |
123 |
energyXT) |
124 |
- VST: changed number of output channels from one stereo to 16 |
125 |
stereo |
126 |
- added channel routing, fxsends and midi maps to the settings |
127 |
stored in the plugin state |
128 |
- performance optimization of AudioChannel::MixTo() and |
129 |
AudioChannel::CopyTo() methods using GCC vector exensions |
130 |
(if available) |
131 |
- ASIO fixes: avoid initializing the device twice, avoid throwing |
132 |
exception when getting parameters from a disconnected device |
133 |
|
134 |
* MIDI driver: |
135 |
- added JACK MIDI driver |
136 |
- dispatch bank select as ordinary CC as well, the user might seriously |
137 |
want to (mis)use it for some purpose ("fixed" in all current MIDI |
138 |
input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME) |
139 |
- bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME, |
140 |
CoreMidi or AU |
141 |
- fixed mingw-w64 compilation error in MME driver |
142 |
- made program change handling in MIDI thread real-time safe by |
143 |
moving the logic to a non-RT thread |
144 |
- fixed minor memory leak in ALSA driver |
145 |
|
146 |
* instruments database: |
147 |
- avoid time consuming samples scanning when adding instruments |
148 |
to the instruments database |
149 |
- added support for handling lost files in the instruments database |
150 |
- Implemented option for adding instruments in separate directories |
151 |
in the instruments database |
152 |
(patch by Chris Cherrett & Andrew Williams, a bit adjusted) |
153 |
- work-around for missing fnmatch function on Windows to make |
154 |
instrument database compilable |
155 |
- added instrument database support on Windows |
156 |
works with both standalone mode and VST plugin. |
157 |
the instruments DB file is located in |
158 |
%USERPROFILE%\.linuxsampler\instruments.db which allows different |
159 |
databases for each windows user |
160 |
if no DB is present it automatically creates the .linuxsampler subdir |
161 |
and then creates an empty DB |
162 |
- fixed recursive import, which was broken on Windows |
163 |
|
164 |
* Gigasampler format engine: |
165 |
- fixed a memory leak that could happen when a channel was deleted |
166 |
while notes were playing |
167 |
- made it possible to load an instrument even if the audio thread |
168 |
isn't running |
169 |
- added partial support for the "Controller Triggered" MIDI rule, |
170 |
enough for piano gigs with pedal noise samples |
171 |
- minor fix: only mark FX sends as being modified if really the |
172 |
respective FX send MIDI controller was used |
173 |
- added support for GM global device volume SysEx message |
174 |
(can be selected at compile time to either apply globally to the |
175 |
whole sampler [default] or only to the sampler channels that are |
176 |
connected to the respective MIDI input port the SysEx message arrived |
177 |
on) |
178 |
- bugfix: notes triggered at position 0 in the audio buffer were |
179 |
sometimes wrongly killed in the same buffer, causing no sound to |
180 |
be played |
181 |
- added support for chromatic / drumkit mode Roland GS Sysex message |
182 |
which is usally used to switch a part between chromatic sounds and |
183 |
drumkit sounds (as opposed to their common default setting of MIDI |
184 |
part 10 being a drumkit part and all other ones chromatic parts), in |
185 |
LS however one can switch between the first 16 MIDI instrument maps |
186 |
defined for the sampler |
187 |
- made it possible to create multiple sample channels even if the |
188 |
audio thread isn't running |
189 |
- fixed crash when removing channel with active voices (#116) |
190 |
- bugfix: on sample reference changes (instrument editor), only |
191 |
un-cache the respective sample if it's really not used by any |
192 |
sampler engine anymore |
193 |
- re-cache samples in case they were changed by an instrument editor, |
194 |
e.g. when a sample was added while playing (#82) |
195 |
- fixed hanging notes which occured when note-off event had the exact |
196 |
same time stamp as the voice's note-on event and occured both in the |
197 |
same audio fragment cycle (fixes bug #112) |
198 |
- added support for the "fine tune" and "pitch bend range" |
199 |
instrument-level gig parameters |
200 |
- fixed minor artifacts in pitch bend handling |
201 |
- added support for GS Reset SysEx message |
202 |
- allow gig files to use unlimited downward pitch shifting |
203 |
- added a limit check for upward pitch shifting |
204 |
- bugfix: sometimes, when playing a note twice fast, the second |
205 |
note was silent |
206 |
- fixed crash happening when a pitch bend event arrived at the |
207 |
same time a new instrument was loading |
208 |
|
209 |
* LSCP server: |
210 |
- added new LSCP event "CHANNEL_MIDI" which can be used by frontends to |
211 |
react on MIDI data arriving on certain sampler channels (so far only |
212 |
Note-On and Note-Off events are sent via this LSCP event) |
213 |
- added new LSCP event "DEVICE_MIDI" which can be used by frontends to |
214 |
react on MIDI data arriving on certain MIDI input devices (so far only |
215 |
Note-On and Note-Off events are sent via this LSCP event) |
216 |
- added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and |
217 |
SET DB_INSTRUMENT FILE_PATH |
218 |
- added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by |
219 |
frontends to send MIDI messages to specific sampler channel |
220 |
- added two additional fields to GET FILE INSTRUMENT INFO command - |
221 |
KEY_BINDINGS and KEYSWITCH_BINDINGS |
222 |
- bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications |
223 |
was incorrect |
224 |
- Optimized the retrieval of the MIDI instrument mappings |
225 |
- added new LSCP command "SET VOICES" to globally alter the maximum |
226 |
amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will |
227 |
be triggered respectively |
228 |
- added new LSCP command "SET STREAMS" to globally alter the maximum |
229 |
amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS" |
230 |
which will be triggered respectively |
231 |
- bugfix: retry if "select" returns EINTR (this fixes a crash when |
232 |
a gigedit file dialog is opened) |
233 |
- close all connections when LSCPServer is deleted |
234 |
- hard close of all sockets on exit |
235 |
- bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME |
236 |
driver |
237 |
|
238 |
* Bug fixes: |
239 |
- fixed a crash which occurs when removing a sampler channel waiting |
240 |
to start instrument loading after another channel |
241 |
- fixed a crash which occurs when removing a sampler channel with |
242 |
instrument loading in progress (bug #113) |
243 |
- fixed termination caused by uncaught exception when adding MIDI |
244 |
instrument with PERSISTENT load mode |
245 |
- fixed possible iterator invalidations when resetting the sampler |
246 |
- fixed memory leaks when issuing the following LSCP commands: |
247 |
GET AUDIO_OUTPUT_DRIVER INFO |
248 |
GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO |
249 |
GET MIDI_INPUT_DRIVER INFO |
250 |
GET MIDI_INPUT_DRIVER_PARAMETER INFO |
251 |
- fixed possible compilation error when sqlite is not present |
252 |
- fixed orphaned pointers when setting maximum voices limit (bug #118) |
253 |
- fixed crash when changing the audio output device of a sampler |
254 |
channel with loaded instrument and start playing notes |
255 |
- fixed endless loop in Engine::SuspendAll() (bug #120) |
256 |
- fixed a low-level atomic load function that was broken on 64-bit |
257 |
PowerPC, which probably could cause crashes on that platform |
258 |
- fixed a memory management error which could cause a crash when a |
259 |
plugin was unloaded |
260 |
- bugfix: two private structs had the same name, which could cause |
261 |
problems if the linker chose the wrong constructor |
262 |
- fixed low-level ConditionServer usage bug that caused lockups on |
263 |
Windows |
264 |
|
265 |
|
266 |
Version 0.5.1 (6 December 2007) |
267 |
|
268 |
* packaging changes: |
269 |
- added autoconf checks for pthread library |
270 |
- added autoconf check for pthread bug found on certain NPTL-enabled |
271 |
glibc versions (see Gentoo bug report #194076) |
272 |
- added autoconf checks for MS Windows |
273 |
|
274 |
* general changes: |
275 |
- bugfix: the thread used by an editor plugin didn't die when the |
276 |
editor closed |
277 |
- bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero |
278 |
out all the space. operator--() did not apply size_mask after |
279 |
decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in |
280 |
order to avoid problems with the _NonVolatileReader functions. |
281 |
- bugfix: Stream.h: added a missing divide by BytesPerSample in |
282 |
GetWriteSpace(). Since this function is currently only used in |
283 |
the stream's qsort() compare function, it didn't trigger any |
284 |
bugs. |
285 |
- Resampler.h, Synthesizer.h: cubic interpolation now works in |
286 |
24bit mode too. Faster method to read 24bit words on little |
287 |
endian machines (x86): replaced 3 byte reads + shifts with a 1 |
288 |
unaligned 32bit read and shift |
289 |
- experimental support for MS Windows (MIDI input via MME, AUDIO |
290 |
output via ASIO) |
291 |
- made handling of SIGINT signal (Ctrl-C) a bit more robust |
292 |
- support for monitoring the total number of active disk streams |
293 |
(new LSCP commands: GET TOTAL_STREAM_COUNT, |
294 |
SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT) |
295 |
|
296 |
* AUDIO driver: |
297 |
- added Windows ASIO low latency audio driver |
298 |
|
299 |
* MIDI driver: |
300 |
- added MME Windows MIDI driver |
301 |
|
302 |
* LSCP server: |
303 |
- added support for Windows style path / filenames, however with |
304 |
forward slash path separators instead of backslash |
305 |
(i.e. "C:/foo/bar.gig") |
306 |
- allow naughty liblscp to send non-string device parameters within |
307 |
apostrophes as well |
308 |
- added new LSCP commands: "GET FILE INSTRUMENTS <file>", |
309 |
"LIST FILE INSTRUMENTS <file>" and |
310 |
"GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations |
311 |
about an arbitrary instrument file on the system where the sampler is |
312 |
running on |
313 |
|
314 |
Version 0.5.0 (15 October 2007) |
315 |
|
316 |
* packaging changes: |
317 |
- config.h is not going to be installed along with liblinuxsampler's |
318 |
API header files anymore |
319 |
- only the API relevant header (and source) files will be exported to |
320 |
the Doxygen API documentation (explicitly listed in Doxyfile.in) |
321 |
- added completely new XCode project files for Mac OSX which is now |
322 |
capable to execute our autoconf environment, thus no need anymore |
323 |
to maintain the compile time configuration file (osx/version.h) for |
324 |
OSX manually (patch by Toshi Nagata) |
325 |
- fixed buggy boolean --enable-foo / --disable-foo configure script |
326 |
parameters |
327 |
- global.h now only covers global definitions that are needed for the |
328 |
C++ API header files, all implementation internal global definitions |
329 |
are now in global_private.h |
330 |
- atomic.h is not exposed to the C++ API anymore |
331 |
- no need to include config.h anymore for using LS's API header files |
332 |
- fixed warnings in API doc generation |
333 |
|
334 |
* general changes: |
335 |
- replaced the old, confusing MIDI program change mechanism by a |
336 |
flexible MIDI instrument mapper which allows to map arbitrary |
337 |
(MIDI bank, MIDI program) pairs with arbitrary |
338 |
(engine type, instrument file, file index) triplets which will be |
339 |
loaded on the respective channel when such MIDI program change |
340 |
messages arrive, beside that, each entry allows to define a life-time |
341 |
strategy for the instrument, so the user can define whether the |
342 |
instrument should i.e. be permanently loaded (to be able to switch |
343 |
quickly among sounds) or i.e. loaded just on demand when the |
344 |
respective program change arrives (to safe RAM space), as well as a |
345 |
global volume factor for each entry, so the user can adjust the volume |
346 |
dynamic of his mapped instrument collection without having to modify |
347 |
the instrument files, also one can manage arbitrary amount of such |
348 |
MIDI instrument maps and assign each sampler channel individually |
349 |
a certain map, so that i.e. separation of normal instruments and |
350 |
drumkits is possible |
351 |
- new notification events for tracking changes to audio/MIDI devices, |
352 |
MIDI instrument maps, MIDI instruments, FX sends, global volume. |
353 |
- sampler was limited to load max. 200 instruments in the background |
354 |
due to a constant size RingBuffer FIFO which is now replaced by a |
355 |
dynamic (unlimited) size std::list FIFO |
356 |
- added FX sends, these allow to route audio signals to arbitrary audio |
357 |
output channels for being processed by external effect processors |
358 |
(i.e. jack-rack), the send levels are controllable via arbitrary MIDI |
359 |
controllers |
360 |
- global (sampler wide) volume can now be controlled at runtime |
361 |
- Implemented new, improved notification system |
362 |
- fixed compilation errors regarding OSX |
363 |
(patch by Toshi Nagata) |
364 |
- implemented instruments database |
365 |
- added support for escape sequences to the instruments database |
366 |
- added highly experimental support for on-the-fly instrument editing |
367 |
within the sampler's process (by using instrument editor plugins), |
368 |
you'll notice the new "Registered instrument editors:" message on |
369 |
startup, added a new LSCP command: |
370 |
"EDIT CHANNEL INSTRUMENT <sampler-channel>" |
371 |
to spawn a matching instrument editor for the instrument on the |
372 |
given sampler channel, the plugin path can be overridden at compile |
373 |
time with ./configure --enable-plugin-dir=/some/dir |
374 |
- added experimental code for synchronizing instrument editors hosted |
375 |
in the sampler's process to safely edit instruments while playing |
376 |
without a crash (hopefully) by either suspending single regions |
377 |
wherever possible or if unavoidable whole engine(s) |
378 |
- fixed several issues in fundamental "Thread" class: set scheduling |
379 |
policy and priority on thread level, set a minimum stack size for |
380 |
thread (TODO: a reasonable value yet to be tested), bugfix: non-RT |
381 |
threads simply inherited properties of starting thread instead of |
382 |
setting their own policy and priority |
383 |
- minor fix in our automatic stack trace mechanism on crashes, the |
384 |
main process did not wait for the stack trace process to finish |
385 |
its output |
386 |
- fixed some minor memory leaks |
387 |
- reenabled assembly features support, at the moment only for |
388 |
enabling a fast denormal FPU mode (x86 platforms supporting SSE2) |
389 |
- minor assembly fix in x86 features detection (don't use the PIC |
390 |
register, to avoid relocations in the text segment at runtime) |
391 |
- POSIX callback functions of Thread.h are hidden |
392 |
|
393 |
* MIDI driver: |
394 |
- dispatch bank select (MSB and LSB) messages |
395 |
|
396 |
* audio driver: |
397 |
- the ALSA audio output driver parameters now reflect the correct |
398 |
parameter value ranges for the respective selected sound card |
399 |
(patch by Till Wimmer, a bit fixed and extended) |
400 |
|
401 |
* Gigasampler format engine: |
402 |
- if a filter is used and EG2 finishes before EG1, let the voice |
403 |
die when EG2 has finished (this fixes a problem with clicks and |
404 |
voice starvation for some gigs) |
405 |
- playback is no longer disabled during instrument loading |
406 |
- all notes playing on a channel that changes its instrument keep |
407 |
playing with the old instrument until they get a note off |
408 |
command |
409 |
- EG fix: a release value of zero could cause noises or crash |
410 |
- handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB) |
411 |
- EG fine tuning: when attack is zero the EG starts at a level |
412 |
above max sustain level, which means that there is a decay phase |
413 |
even if sustain is 100% |
414 |
- more EG fixes: the level could sometimes go below zero and cause |

noises or crashes |
416 |
- minor fix of EGDecay (patch by Toshi Nagata) |
417 |
- fixed compiler error when --enable-override-filter-type was |
418 |
supplied to the configure script (fixes #46) |
419 |
- disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS |
420 |
instead of a fix value |
421 |
- behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode), |
422 |
127 (solo mode) only kill voices if the respective mode really |
423 |
changed |
424 |
|
425 |
* LSCP server: |
426 |
- fixed compile time error for old Bison versions |
427 |
(i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata) |
428 |
- parser now supports extended ASCII character set |
429 |
(up to ASCII code 255, i.e. includes now umlauts and accents) |
430 |
- filename arguments in LSCP commands now allow to use escape |
431 |
sequences, that is directly literal as one of: \', \", \\, \n, \r, |
432 |
\f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII |
433 |
code value like \xf2) (fixes bug #24) |
434 |
- the following LSCP commands now also support escape sequences for at |
435 |
least one of their text-based parameters (i.e. name, description): |
436 |
"ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT", |
437 |
"SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND", |
438 |
"SET DB_INSTRUMENT_DIRECTORY NAME", |
439 |
"SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME", |
440 |
"SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS", |
441 |
"FIND DB_INSTRUMENT_DIRECTORIES" |
442 |
- returns verbose syntax errors (line and column where syntax error |
443 |
occured, the unexpected character and the actually expected, possible |
444 |
character(s), the latter only if less than 5 possibilities) |
445 |
- made sure that LSCP syntax is not affected by gigedit locale |
446 |
settings |
447 |
- bugfix regarding strings parameter lists: all comma separated lists |
448 |
of strings were treated as being one string containing commas |
449 |
(fixes #57) |
450 |
|
451 |
* Bug fixes: |
452 |
- fixed crash occurring on certain LSCP scripts (Bug 39) |
453 |
- another thread safety fix for lscp "load engine" and "set |
454 |
channel audio output device" |
455 |
- fixed a crash which occurs when reassigning the same engine |
456 |
on a sampler channel with connected MIDI device |
457 |
- fixed a crash which occurs when changing the number of ports of a MIDI |
458 |
device connected to a sampler channel to number less then or equal |
459 |
to the index of the port to which the sampler channel is connected. |
460 |
- The previous bindings were not been disconnected when altering |
461 |
the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for |
462 |
unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE). |
463 |
- The active stream/voice count statistic was incorrect. |
464 |
- notification events were not been sent for some sampler |
465 |
channel changes |
466 |
- added default min and max values to restrict the number of allowed |
467 |
audio output channels and MIDI input ports |
468 |
- the connection to the PCM interface is now closed when destroying |
469 |
an audio output device |
470 |
- files with slash in their path or filename could not be loaded |
471 |
|
472 |
* test cases: |
473 |
- updated and fixed (haven't been touched in a while) |
474 |
|
475 |
Version 0.4.0 (24 November 2006) |
476 |
|
477 |
* packaging changes: |
478 |
- changed deprecated copyright attribute to license; added ldconfig |
479 |
to post-(un)install steps; added devel package for liblinuxsampler; |
480 |
to linuxsampler.spec (RPM) |
481 |
- install necessary development header files for allowing 3rd party |
482 |
applications to link against liblinuxsampler |
483 |
- liblinuxsampler's API documentation can be generated with 'make docs' |
484 |
(Doxygen required) |
485 |
- added benchmark to automatically detect the best triangle LFO |
486 |
implementation (currently either an integer math solution or a |
487 |
di-harmonic approximation), automatic detection can be overriden |
488 |
with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x |
489 |
configure script argument though (mandatory for cross-compilation) |
490 |
- do not automatically pick optimized gcc flags if the user already |
491 |
provided some on his own (as CXXFLAGS) |
492 |
- added compile time option to disable processing of All-Notes-Off MIDI |
493 |
messages |
494 |
- added compile time options to allow disabling the various audio and |
495 |
MIDI drivers |
496 |
- fixed automatic GCC CPU switch detection on PPC |
497 |
(patch by Ebrahim Mayat) |
498 |
|
499 |
* Gigasampler format engine: |
500 |
- extensive synthesis optimization |
501 |
(reimplementation of EGs and LFO(s), removed synthesis parameter |
502 |
prerendering and the synthesis parameter matrix in general, splitting |
503 |
each audio fragment into subfragments now where each subfragment uses |
504 |
constant pitch and filter coefficients. The volume coefficient is |
505 |
linearly interpolated inside a subfragment, unless |
506 |
--disable-interpolate-volume is set.) |
507 |
- fine tuning of the EG modulation parameters |
508 |
- improved filter cutoff calculation by adding support for the |
509 |
following gig parameters: Cutoff freq (used when no cutoff |
510 |
controller is defined), Control invert, Minimum cutoff, Velocity |
511 |
curve and Velocity range. The keyboard tracking now scales |
512 |
cutoff frequency instead of resonance. |
513 |
- added support for gig parameter Resonance. |
514 |
- fixed bug in sysex handling (patch by Juan Linietsky) |
515 |
- added global volume attenuation of -9 dB (0.35f) to prevent clipping |
516 |
which can be overridden with --enable-global-attenuation |
517 |
- EG fixes: made the length of "attack hold" stage more |
518 |
accurate. Release stage can now start before attack stage |
519 |
ends. Cancel release didn't work when sustain was zero. Attack |
520 |
time now has a minimal value to prevent clicks. |
521 |
- fixed pitch changes larger than one octave |
522 |
- fixed EG3 (pitch envelope) synthesis which was neutral all the time |
523 |
- implemented portamento mode and solo mode (a.k.a 'mono mode'): |
524 |
all modes can be altered via standard GM messages, that is CC5 for |
525 |
altering portamento time, CC65 for enabling / disabling portamento |
526 |
mode, CC126 for enabling solo mode and CC127 for disabling solo mode |
527 |
- fine tuning of the curves for volume (CC7), pan (CC10 and gig |
528 |
parameter) and crossfade |
529 |
- added support for the "attenuation controller threshold" gig |
530 |
parameter |
531 |
- added smoothing of volume changes caused by control change |
532 |
messages |
533 |
- sample loop parameters are now taken from the DimensionRegion |
534 |
instead of the wave chunk |
535 |
- fixed keyswitching for v3 gigs with a number of keyswitch splits |
536 |
not equal to a power of two |
537 |
- reimplementation of the filter algorithm. The new filter is more |
538 |
accurate and supports all gig filter types, including bandreject |
539 |
and lowpass turbo. |
540 |
- real support for 24 bit samples - samples are not truncated to |
541 |
16 bits anymore |
542 |
- support for aftertouch (channel pressure, not polyphonic |
543 |
aftertouch) |
544 |
- LFO1 behaviour fixed (dampening from max volume instead of |
545 |
amplifying from 0) |
546 |
|
547 |
* LSCP server: |
548 |
- fixed application exit on broken pipe error (fixes bug #20) |
549 |
- fixed the notification messages delay due to lack of |
550 |
network activity (fixes bug #26) |
551 |
- fixed parser bug which occured on space(s) within device parameters |
552 |
(e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'") |
553 |
|
554 |
* audio driver: |
555 |
- added aRts audio output driver (by no means RT safe) |
556 |
|
557 |
* MIDI driver: |
558 |
- fixed legacy sysex code which caused dispatching of MIDI SysEx |
559 |
messages several times instead of once |
560 |
- API extension for MIDI drivers which already supply exact time stamps |
561 |
for events (i.e. for offline rendering based MIDI drivers) |
562 |
- added checks for bad MIDI data |
563 |
|
564 |
* linuxsampler application: |
565 |
- show available sampler engine types on startup |
566 |
|
567 |
* general changes: |
568 |
- support for muting sampler channels and solo mode of the same, two new |
569 |
LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new |
570 |
fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were |
571 |
introduced for this, the behavior is the same like on a mixer console |
572 |
(patch by Grigor Iliev, a bit adjusted). Also added configure option |
573 |
--enable-process-muted-channels which can be used to enable the |
574 |
processing of muted channels. |
575 |
- support for sostenuto pedal |
576 |
- support for monitoring the total number of active voices |
577 |
(new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX, |
578 |
SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT) |
579 |
- fixed some memory management errors |
580 |
- fixed some concurrency problems that could lead to crashes when |
581 |
LSCP commands were executed |
582 |
- fixed crash when instrument loading failed previously on the same |
583 |
sampler channel (fixes bug #36) |
584 |
|
585 |
Version 0.3.3 (15 July 2005) |
586 |
|
587 |
* packaging changes: |
588 |
- fixed compilation with gcc 4.0 |
589 |
|
590 |
* Gigasampler format engine: |
591 |
- LFO preprocessing was performed even though the respective LFO was |
592 |
disabled by the instrument patch (minor efficiency fix) |
593 |
- if period time of chosen audio device is too small (< MIN_RELEASE_TIME) |
594 |
for volume ramp downs in the same fragment (needed for current voice |
595 |
stealing implementation) then simply inform the user with a warning |
596 |
about possible click sounds and reduce the volume ramp down |
597 |
appropriately instead of cancelling the audio device connection |
598 |
|
599 |
Version 0.3.2 (24 June 2005) |
600 |
|
601 |
* packaging changes: |
602 |
- updated autotools build files to compile on OS X |
603 |
(conditional compilation of CoreMIDI and MidiShare drivers) |
604 |
- hand-crafted assembly optimization code can be disabled with |
605 |
'./configure --disable-asm' (definitely not recommended) |
606 |
- fixed 'make dist' rule to include all necessary files |
607 |
- require automake (>= 1.5) for 'make -f Makefile.cvs' |
608 |
(due to 'dist-bzip2' automake option) |
609 |
|
610 |
* Gigasampler format engine: |
611 |
- support for the gig parameters for "release velocity response" curves |
612 |
- fine tuning of the EGADSR envelope |
613 |
- volume of release triggered samples now depends on note-on velocity, |
614 |
note length and gig parameter "release trigger decay" instead of |
615 |
note-off velocity. |
616 |
- revised voice stealing |
617 |
(fixes crash and endless loop caused by voice stealing) |
618 |
- don't reset scale tuning on instrument or audio output device change |
619 |
- handle key group conflicts right at the beginning of each fragment |
620 |
instead of when the respective voice is actually launched |
621 |
(fixes undefined behavior if stolen voices belonged to a key group - |
622 |
this case was followed by a "killed voice survived" error message) |
623 |
- fixed minor issue with null/silence samples |
624 |
(those stole voices even though they don't need a voice at all which |
625 |
resulted in "voice stealing didn't work out" messages) |
626 |
- don't reset volume, pan, pitch and MIDI controller values on |
627 |
instrument or audio output device change |
628 |
|
629 |
* LSCP server: |
630 |
- fixed some crashes (patch by Grigor Iliev, fixes #19) |
631 |
- fixed LSCP event "CHANNEL_INFO" notification |
632 |
(e.g. did not notify on volume changes or MIDI program change events) |
633 |
|
634 |
* linuxsampler application: |
635 |
- added command line parameters --lscp-addr and --lscp-port to override |
636 |
default IP address and port of LSCP server |
637 |
|
638 |
Version 0.3.1 (24 May 2005) |
639 |
|
640 |
* initial release |
