|
- autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly, |
| 5 |
|
causing e.g. the libgig test to fail when |
| 6 |
|
"./configure --disable-jack-driver" was used |
| 7 |
|
(patch by Alexis Ballier) |
| 8 |
|
- fixed compilation with gcc 4.3 |
| 9 |
|
- fixes for building on OS X (thanks to Ebrahim Mayat for testing) |
| 10 |
|
- fixed configure so it detects x86_64 (#107) |
| 11 |
|
- fixes for building with newer MinGW versions |
| 12 |
|
- fix for building with bison 2.4 (#111) |
| 13 |
|
- fixed building with libgig installed in a non-standard directory |
| 14 |
|
|
| 15 |
|
* general changes: |
| 16 |
|
- bugfix: on some POSIX systems instrument editor plugins refused to |
| 17 |
|
load as we used a non-portable Linux specific struct field |
| 18 |
|
(fixes bug #70, patch by Ronald Baljeu) |
| 19 |
|
- fixed endless loop which occured when loading an instrument editor |
| 20 |
|
plugin DLL on Windows systems failed |
| 21 |
|
- fixed memory leaks that occurred when liblinuxsampler was unloaded |
| 22 |
|
- optimized the SynchronizedConfig class so it doesn't wait |
| 23 |
|
unnecessarily long after an update |
| 24 |
|
- added support for notifying instrument editors on note-on / note-off |
| 25 |
|
events (e.g. to highlight the pressed keys on the virtual keyboard |
| 26 |
|
of gigedit) |
| 27 |
|
- added support for triggering notes by instrument editors (see above) |
| 28 |
|
- be verbose on DLL load errors (on Linux) |
| 29 |
|
- fixed di-harmonic triangle LFO implementation (this LFO implementation |
| 30 |
|
is only used by very few systems, most pick the int math |
| 31 |
|
implementation, which is usually faster) |
| 32 |
|
- fixes for audio drivers with varying buffer sizes |
| 33 |
|
- experimental support for running LinuxSampler as a DSSI, LV2 and |
| 34 |
|
VST plugin |
| 35 |
|
- notification events for stream/voice count statistics are now sent |
| 36 |
|
only when there are actual changes |
| 37 |
|
- added memory ordering constraints to improve stability on |
| 38 |
|
multi-core and multi-cpu systems |
| 39 |
|
- maximum voices and disk streams can now be altered at runtime |
| 40 |
|
- fixed CPU feature detection on x86_64 (maybe fixes #108) |
| 41 |
|
- automatic stacktrace mechanism is now turned off by default and can |
| 42 |
|
be switched on by command line option "--stacktrace" (the automatic |
| 43 |
|
stacktrace mechanism seems to be broken on most systems at the moment) |
| 44 |
|
- C++ API method InstrumentManager::LaunchInstrumentEditor() now returns |
| 45 |
|
a pointer to the launched InstrumentEditor object |
| 46 |
|
- added optional 3rd party user data parameter for following |
| 47 |
|
liblinuxsampler C++ API methods: InstrumentEditor::Main(), |
| 48 |
|
InstrumentEditor::Launch(), |
| 49 |
|
InstrumentManager::LaunchInstrumentEditor() |
| 50 |
|
- theoretical fix: made SynchronizedConfig follow C++0x memory |
| 51 |
|
model more strictly |
| 52 |
|
|
| 53 |
|
* audio driver: |
| 54 |
|
- removed the nonsense audio channel constraint (which was hard coded to |
| 55 |
|
max. 100 audio channels) for most audio drivers |
| 56 |
|
- JACK audio driver did not offer a device parameter "SAMPLERATE" as |
| 57 |
|
opposed to the LSCP specs |
| 58 |
|
- bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK) |
| 59 |
|
reflected the wrong value |
| 60 |
|
- fixed a memory management bug in ASIO driver |
| 61 |
|
- Makefile fix: JACK_CFLAGS wasn't used |
| 62 |
|
- JACK: use jack_client_open instead of the deprecated |
| 63 |
|
jack_client_new |
| 64 |
|
- added (experimental) CoreAudio driver |
| 65 |
|
- applied old fixes to the ASIO driver that were included in the |
| 66 |
|
previous binary release but accidentally never committed to CVS |
| 67 |
|
(fixes #117) |
| 68 |
|
- fixes for ASIO on mingw-w64 (iasio wrapper is not needed on |
| 69 |
|
win64) |
| 70 |
|
|
| 71 |
|
* MIDI driver: |
| 72 |
|
- added JACK MIDI driver |
| 73 |
|
- dispatch bank select as ordinary CC as well, the user might seriously |
| 74 |
|
want to (mis)use it for some purpose ("fixed" in all current MIDI |
| 75 |
|
input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME) |
| 76 |
|
- bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME, |
| 77 |
|
CoreMidi or AU |
| 78 |
|
- fixed mingw-w64 compilation error in MME driver |
| 79 |
|
|
| 80 |
|
* instruments database: |
| 81 |
|
- avoid time consuming samples scanning when adding instruments |
| 82 |
|
to the instruments database |
| 83 |
|
- added support for handling lost files in the instruments database |
| 84 |
|
- Implemented option for adding instruments in separate directories |
| 85 |
|
in the instruments database |
| 86 |
|
(patch by Chris Cherrett & Andrew Williams, a bit adjusted) |
| 87 |
|
|
| 88 |
|
* Gigasampler format engine: |
| 89 |
|
- fixed a memory leak that could happen when a channel was deleted |
| 90 |
|
while notes were playing |
| 91 |
|
- made it possible to load an instrument even if the audio thread |
| 92 |
|
isn't running |
| 93 |
|
- added partial support for the "Controller Triggered" MIDI rule, |
| 94 |
|
enough for piano gigs with pedal noise samples |
| 95 |
|
- minor fix: only mark FX sends as being modified if really the |
| 96 |
|
respective FX send MIDI controller was used |
| 97 |
|
- added support for GM global device volume SysEx message |
| 98 |
|
(can be selected at compile time to either apply globally to the |
| 99 |
|
whole sampler [default] or only to the sampler channels that are |
| 100 |
|
connected to the respective MIDI input port the SysEx message arrived |
| 101 |
|
on) |
| 102 |
|
- bugfix: notes triggered at position 0 in the audio buffer were |
| 103 |
|
sometimes wrongly killed in the same buffer, causing no sound to |
| 104 |
|
be played |
| 105 |
|
- added support for chromatic / drumkit mode Roland GS Sysex message |
| 106 |
|
which is usally used to switch a part between chromatic sounds and |
| 107 |
|
drumkit sounds (as opposed to their common default setting of MIDI |
| 108 |
|
part 10 being a drumkit part and all other ones chromatic parts), in |
| 109 |
|
LS however one can switch between the first 16 MIDI instrument maps |
| 110 |
|
defined for the sampler |
| 111 |
|
- made it possible to create multiple sample channels even if the |
| 112 |
|
audio thread isn't running |
| 113 |
|
- fixed crash when removing channel with active voices (#116) |
| 114 |
|
- bugfix: on sample reference changes (instrument editor), only |
| 115 |
|
un-cache the respective sample if it's really not used by any |
| 116 |
|
sampler engine anymore |
| 117 |
|
- re-cache samples in case they were changed by an instrument editor, |
| 118 |
|
e.g. when a sample was added while playing (#82) |
| 119 |
|
- fixed hanging notes which occured when note-off event had the exact |
| 120 |
|
same time stamp as the voice's note-on event and occured both in the |
| 121 |
|
same audio fragment cycle (fixes bug #112) |
| 122 |
|
- added support for the "fine tune" and "pitch bend range" |
| 123 |
|
instrument-level gig parameters |
| 124 |
|
- fixed minor artifacts in pitch bend handling |
| 125 |
|
- added support for GS Reset SysEx message |
| 126 |
|
- allow gig files to use unlimited downward pitch shifting |
| 127 |
|
- added a limit check for upward pitch shifting |
| 128 |
|
|
| 129 |
|
* LSCP server: |
| 130 |
|
- added new LSCP event "CHANNEL_MIDI" which can be used by frontends to |
| 131 |
|
react on MIDI data arriving on certain sampler channels (so far only |
| 132 |
|
Note-On and Note-Off events are sent via this LSCP event) |
| 133 |
|
- added new LSCP event "DEVICE_MIDI" which can be used by frontends to |
| 134 |
|
react on MIDI data arriving on certain MIDI input devices (so far only |
| 135 |
|
Note-On and Note-Off events are sent via this LSCP event) |
| 136 |
|
- added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and |
| 137 |
|
SET DB_INSTRUMENT FILE_PATH |
| 138 |
|
- added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by |
| 139 |
|
frontends to send MIDI messages to specific sampler channel |
| 140 |
|
- added two additional fields to GET FILE INSTRUMENT INFO command - |
| 141 |
|
KEY_BINDINGS and KEYSWITCH_BINDINGS |
| 142 |
|
- bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications |
| 143 |
|
was incorrect |
| 144 |
|
- Optimized the retrieval of the MIDI instrument mappings |
| 145 |
|
- added new LSCP command "SET VOICES" to globally alter the maximum |
| 146 |
|
amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will |
| 147 |
|
be triggered respectively |
| 148 |
|
- added new LSCP command "SET STREAMS" to globally alter the maximum |
| 149 |
|
amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS" |
| 150 |
|
which will be triggered respectively |
| 151 |
|
- bugfix: retry if "select" returns EINTR (this fixes a crash when |
| 152 |
|
a gigedit file dialog is opened) |
| 153 |
|
- close all connections when LSCPServer is deleted |
| 154 |
|
- hard close of all sockets on exit |
| 155 |
|
|
| 156 |
|
* Bug fixes: |
| 157 |
|
- fixed a crash which occurs when removing a sampler channel waiting |
| 158 |
|
to start instrument loading after another channel |
| 159 |
|
- fixed a crash which occurs when removing a sampler channel with |
| 160 |
|
instrument loading in progress (bug #113) |
| 161 |
|
- fixed termination caused by uncaught exception when adding MIDI |
| 162 |
|
instrument with PERSISTENT load mode |
| 163 |
|
- fixed possible iterator invalidations when resetting the sampler |
| 164 |
|
- fixed memory leaks when issuing the following LSCP commands: |
| 165 |
|
GET AUDIO_OUTPUT_DRIVER INFO |
| 166 |
|
GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO |
| 167 |
|
GET MIDI_INPUT_DRIVER INFO |
| 168 |
|
GET MIDI_INPUT_DRIVER_PARAMETER INFO |
| 169 |
|
- fixed possible compilation error when sqlite is not present |
| 170 |
|
- fixed orphaned pointers when setting maximum voices limit (bug #118) |
| 171 |
|
- fixed crash when changing the audio output device of a sampler |
| 172 |
|
channel with loaded instrument and start playing notes |
| 173 |
|
- fixed endless loop in Engine::SuspendAll() (bug #120) |
| 174 |
|
- fixed a low-level atomic load function that was broken on 64-bit |
| 175 |
|
PowerPC, which probably could cause crashes on that platform |
| 176 |
|
- fixed a memory management error which could cause a crash when a |
| 177 |
|
plugin was unloaded |
| 178 |
|
|
| 179 |
|
|
| 180 |
|
Version 0.5.1 (6 December 2007) |
| 181 |
|
|
| 182 |
|
* packaging changes: |
| 183 |
|
- added autoconf checks for pthread library |
| 184 |
|
- added autoconf check for pthread bug found on certain NPTL-enabled |
| 185 |
|
glibc versions (see Gentoo bug report #194076) |
| 186 |
|
- added autoconf checks for MS Windows |
| 187 |
|
|
| 188 |
|
* general changes: |
| 189 |
|
- bugfix: the thread used by an editor plugin didn't die when the |
| 190 |
|
editor closed |
| 191 |
|
- bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero |
| 192 |
|
out all the space. operator--() did not apply size_mask after |
| 193 |
|
decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in |
| 194 |
|
order to avoid problems with the _NonVolatileReader functions. |
| 195 |
|
- bugfix: Stream.h: added a missing divide by BytesPerSample in |
| 196 |
|
GetWriteSpace(). Since this function is currently only used in |
| 197 |
|
the stream's qsort() compare function, it didn't trigger any |
| 198 |
|
bugs. |
| 199 |
|
- Resampler.h, Synthesizer.h: cubic interpolation now works in |
| 200 |
|
24bit mode too. Faster method to read 24bit words on little |
| 201 |
|
endian machines (x86): replaced 3 byte reads + shifts with a 1 |
| 202 |
|
unaligned 32bit read and shift |
| 203 |
|
- experimental support for MS Windows (MIDI input via MME, AUDIO |
| 204 |
|
output via ASIO) |
| 205 |
|
- made handling of SIGINT signal (Ctrl-C) a bit more robust |
| 206 |
|
- support for monitoring the total number of active disk streams |
| 207 |
|
(new LSCP commands: GET TOTAL_STREAM_COUNT, |
| 208 |
|
SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT) |
| 209 |
|
|
| 210 |
|
* AUDIO driver: |
| 211 |
|
- added Windows ASIO low latency audio driver |
| 212 |
|
|
| 213 |
|
* MIDI driver: |
| 214 |
|
- added MME Windows MIDI driver |
| 215 |
|
|
| 216 |
|
* LSCP server: |
| 217 |
|
- added support for Windows style path / filenames, however with |
| 218 |
|
forward slash path separators instead of backslash |
| 219 |
|
(i.e. "C:/foo/bar.gig") |
| 220 |
|
- allow naughty liblscp to send non-string device parameters within |
| 221 |
|
apostrophes as well |
| 222 |
|
- added new LSCP commands: "GET FILE INSTRUMENTS <file>", |
| 223 |
|
"LIST FILE INSTRUMENTS <file>" and |
| 224 |
|
"GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations |
| 225 |
|
about an arbitrary instrument file on the system where the sampler is |
| 226 |
|
running on |
| 227 |
|
|
| 228 |
|
Version 0.5.0 (15 October 2007) |
| 229 |
|
|
| 230 |
|
* packaging changes: |
| 231 |
|
- config.h is not going to be installed along with liblinuxsampler's |
| 232 |
|
API header files anymore |
| 233 |
|
- only the API relevant header (and source) files will be exported to |
| 234 |
|
the Doxygen API documentation (explicitly listed in Doxyfile.in) |
| 235 |
|
- added completely new XCode project files for Mac OSX which is now |
| 236 |
|
capable to execute our autoconf environment, thus no need anymore |
| 237 |
|
to maintain the compile time configuration file (osx/version.h) for |
| 238 |
|
OSX manually (patch by Toshi Nagata) |
| 239 |
|
- fixed buggy boolean --enable-foo / --disable-foo configure script |
| 240 |
|
parameters |
| 241 |
|
- global.h now only covers global definitions that are needed for the |
| 242 |
|
C++ API header files, all implementation internal global definitions |
| 243 |
|
are now in global_private.h |
| 244 |
|
- atomic.h is not exposed to the C++ API anymore |
| 245 |
|
- no need to include config.h anymore for using LS's API header files |
| 246 |
|
- fixed warnings in API doc generation |
| 247 |
|
|
| 248 |
|
* general changes: |
| 249 |
|
- replaced the old, confusing MIDI program change mechanism by a |
| 250 |
|
flexible MIDI instrument mapper which allows to map arbitrary |
| 251 |
|
(MIDI bank, MIDI program) pairs with arbitrary |
| 252 |
|
(engine type, instrument file, file index) triplets which will be |
| 253 |
|
loaded on the respective channel when such MIDI program change |
| 254 |
|
messages arrive, beside that, each entry allows to define a life-time |
| 255 |
|
strategy for the instrument, so the user can define whether the |
| 256 |
|
instrument should i.e. be permanently loaded (to be able to switch |
| 257 |
|
quickly among sounds) or i.e. loaded just on demand when the |
| 258 |
|
respective program change arrives (to safe RAM space), as well as a |
| 259 |
|
global volume factor for each entry, so the user can adjust the volume |
| 260 |
|
dynamic of his mapped instrument collection without having to modify |
| 261 |
|
the instrument files, also one can manage arbitrary amount of such |
| 262 |
|
MIDI instrument maps and assign each sampler channel individually |
| 263 |
|
a certain map, so that i.e. separation of normal instruments and |
| 264 |
|
drumkits is possible |
| 265 |
|
- new notification events for tracking changes to audio/MIDI devices, |
| 266 |
|
MIDI instrument maps, MIDI instruments, FX sends, global volume. |
| 267 |
|
- sampler was limited to load max. 200 instruments in the background |
| 268 |
|
due to a constant size RingBuffer FIFO which is now replaced by a |
| 269 |
|
dynamic (unlimited) size std::list FIFO |
| 270 |
|
- added FX sends, these allow to route audio signals to arbitrary audio |
| 271 |
|
output channels for being processed by external effect processors |
| 272 |
|
(i.e. jack-rack), the send levels are controllable via arbitrary MIDI |
| 273 |
|
controllers |
| 274 |
|
- global (sampler wide) volume can now be controlled at runtime |
| 275 |
|
- Implemented new, improved notification system |
| 276 |
|
- fixed compilation errors regarding OSX |
| 277 |
|
(patch by Toshi Nagata) |
| 278 |
|
- implemented instruments database |
| 279 |
|
- added support for escape sequences to the instruments database |
| 280 |
|
- added highly experimental support for on-the-fly instrument editing |
| 281 |
|
within the sampler's process (by using instrument editor plugins), |
| 282 |
|
you'll notice the new "Registered instrument editors:" message on |
| 283 |
|
startup, added a new LSCP command: |
| 284 |
|
"EDIT CHANNEL INSTRUMENT <sampler-channel>" |
| 285 |
|
to spawn a matching instrument editor for the instrument on the |
| 286 |
|
given sampler channel, the plugin path can be overridden at compile |
| 287 |
|
time with ./configure --enable-plugin-dir=/some/dir |
| 288 |
|
- added experimental code for synchronizing instrument editors hosted |
| 289 |
|
in the sampler's process to safely edit instruments while playing |
| 290 |
|
without a crash (hopefully) by either suspending single regions |
| 291 |
|
wherever possible or if unavoidable whole engine(s) |
| 292 |
|
- fixed several issues in fundamental "Thread" class: set scheduling |
| 293 |
|
policy and priority on thread level, set a minimum stack size for |
| 294 |
|
thread (TODO: a reasonable value yet to be tested), bugfix: non-RT |
| 295 |
|
threads simply inherited properties of starting thread instead of |
| 296 |
|
setting their own policy and priority |
| 297 |
|
- minor fix in our automatic stack trace mechanism on crashes, the |
| 298 |
|
main process did not wait for the stack trace process to finish |
| 299 |
|
its output |
| 300 |
|
- fixed some minor memory leaks |
| 301 |
|
- reenabled assembly features support, at the moment only for |
| 302 |
|
enabling a fast denormal FPU mode (x86 platforms supporting SSE2) |
| 303 |
|
- minor assembly fix in x86 features detection (don't use the PIC |
| 304 |
|
register, to avoid relocations in the text segment at runtime) |
| 305 |
|
- POSIX callback functions of Thread.h are hidden |
| 306 |
|
|
| 307 |
|
* MIDI driver: |
| 308 |
|
- dispatch bank select (MSB and LSB) messages |
| 309 |
|
|
| 310 |
|
* audio driver: |
| 311 |
|
- the ALSA audio output driver parameters now reflect the correct |
| 312 |
|
parameter value ranges for the respective selected sound card |
| 313 |
|
(patch by Till Wimmer, a bit fixed and extended) |
| 314 |
|
|
| 315 |
|
* Gigasampler format engine: |
| 316 |
|
- if a filter is used and EG2 finishes before EG1, let the voice |
| 317 |
|
die when EG2 has finished (this fixes a problem with clicks and |
| 318 |
|
voice starvation for some gigs) |
| 319 |
|
- playback is no longer disabled during instrument loading |
| 320 |
|
- all notes playing on a channel that changes its instrument keep |
| 321 |
|
playing with the old instrument until they get a note off |
| 322 |
|
command |
| 323 |
|
- EG fix: a release value of zero could cause noises or crash |
| 324 |
|
- handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB) |
| 325 |
|
- EG fine tuning: when attack is zero the EG starts at a level |
| 326 |
|
above max sustain level, which means that there is a decay phase |
| 327 |
|
even if sustain is 100% |
| 328 |
|
- more EG fixes: the level could sometimes go below zero and cause |
| 329 |
|
noises or crashes |
| 330 |
|
- minor fix of EGDecay (patch by Toshi Nagata) |
| 331 |
|
- fixed compiler error when --enable-override-filter-type was |
| 332 |
|
supplied to the configure script (fixes #46) |
| 333 |
|
- disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS |
| 334 |
|
instead of a fix value |
| 335 |
|
- behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode), |
| 336 |
|
127 (solo mode) only kill voices if the respective mode really |
| 337 |
|
changed |
| 338 |
|
|
| 339 |
|
* LSCP server: |
| 340 |
|
- fixed compile time error for old Bison versions |
| 341 |
|
(i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata) |
| 342 |
|
- parser now supports extended ASCII character set |
| 343 |
|
(up to ASCII code 255, i.e. includes now umlauts and accents) |
| 344 |
|
- filename arguments in LSCP commands now allow to use escape |
| 345 |
|
sequences, that is directly literal as one of: \', \", \\, \n, \r, |
| 346 |
|
\f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII |
| 347 |
|
code value like \xf2) (fixes bug #24) |
| 348 |
|
- the following LSCP commands now also support escape sequences for at |
| 349 |
|
least one of their text-based parameters (i.e. name, description): |
| 350 |
|
"ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT", |
| 351 |
|
"SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND", |
| 352 |
|
"SET DB_INSTRUMENT_DIRECTORY NAME", |
| 353 |
|
"SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME", |
| 354 |
|
"SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS", |
| 355 |
|
"FIND DB_INSTRUMENT_DIRECTORIES" |
| 356 |
|
- returns verbose syntax errors (line and column where syntax error |
| 357 |
|
occured, the unexpected character and the actually expected, possible |
| 358 |
|
character(s), the latter only if less than 5 possibilities) |
| 359 |
|
- made sure that LSCP syntax is not affected by gigedit locale |
| 360 |
|
settings |
| 361 |
|
- bugfix regarding strings parameter lists: all comma separated lists |
| 362 |
|
of strings were treated as being one string containing commas |
| 363 |
|
(fixes #57) |
| 364 |
|
|
| 365 |
|
* Bug fixes: |
| 366 |
|
- fixed crash occurring on certain LSCP scripts (Bug 39) |
| 367 |
|
- another thread safety fix for lscp "load engine" and "set |
| 368 |
|
channel audio output device" |
| 369 |
|
- fixed a crash which occurs when reassigning the same engine |
| 370 |
|
on a sampler channel with connected MIDI device |
| 371 |
|
- fixed a crash which occurs when changing the number of ports of a MIDI |
| 372 |
|
device connected to a sampler channel to number less then or equal |
| 373 |
|
to the index of the port to which the sampler channel is connected. |
| 374 |
|
- The previous bindings were not been disconnected when altering |
| 375 |
|
the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for |
| 376 |
|
unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE). |
| 377 |
|
- The active stream/voice count statistic was incorrect. |
| 378 |
|
- notification events were not been sent for some sampler |
| 379 |
|
channel changes |
| 380 |
|
- added default min and max values to restrict the number of allowed |
| 381 |
|
audio output channels and MIDI input ports |
| 382 |
|
- the connection to the PCM interface is now closed when destroying |
| 383 |
|
an audio output device |
| 384 |
|
- files with slash in their path or filename could not be loaded |
| 385 |
|
|
| 386 |
|
* test cases: |
| 387 |
|
- updated and fixed (haven't been touched in a while) |
| 388 |
|
|
| 389 |
|
Version 0.4.0 (24 November 2006) |
| 390 |
|
|
| 391 |
|
* packaging changes: |
| 392 |
|
- changed deprecated copyright attribute to license; added ldconfig |
| 393 |
|
to post-(un)install steps; added devel package for liblinuxsampler; |
| 394 |
|
to linuxsampler.spec (RPM) |
| 395 |
|
- install necessary development header files for allowing 3rd party |
| 396 |
|
applications to link against liblinuxsampler |
| 397 |
|
- liblinuxsampler's API documentation can be generated with 'make docs' |
| 398 |
|
(Doxygen required) |
| 399 |
|
- added benchmark to automatically detect the best triangle LFO |
| 400 |
|
implementation (currently either an integer math solution or a |
| 401 |
|
di-harmonic approximation), automatic detection can be overriden |
| 402 |
|
with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x |
| 403 |
|
configure script argument though (mandatory for cross-compilation) |
| 404 |
|
- do not automatically pick optimized gcc flags if the user already |
| 405 |
|
provided some on his own (as CXXFLAGS) |
| 406 |
|
- added compile time option to disable processing of All-Notes-Off MIDI |
| 407 |
|
messages |
| 408 |
|
- added compile time options to allow disabling the various audio and |
| 409 |
|
MIDI drivers |
| 410 |
|
- fixed automatic GCC CPU switch detection on PPC |
| 411 |
|
(patch by Ebrahim Mayat) |
| 412 |
|
|
| 413 |
|
* Gigasampler format engine: |
| 414 |
|
- extensive synthesis optimization |
| 415 |
|
(reimplementation of EGs and LFO(s), removed synthesis parameter |
| 416 |
|
prerendering and the synthesis parameter matrix in general, splitting |
| 417 |
|
each audio fragment into subfragments now where each subfragment uses |
| 418 |
|
constant pitch and filter coefficients. The volume coefficient is |
| 419 |
|
linearly interpolated inside a subfragment, unless |
| 420 |
|
--disable-interpolate-volume is set.) |
| 421 |
|
- fine tuning of the EG modulation parameters |
| 422 |
|
- improved filter cutoff calculation by adding support for the |
| 423 |
|
following gig parameters: Cutoff freq (used when no cutoff |
| 424 |
|
controller is defined), Control invert, Minimum cutoff, Velocity |
| 425 |
|
curve and Velocity range. The keyboard tracking now scales |
| 426 |
|
cutoff frequency instead of resonance. |
| 427 |
|
- added support for gig parameter Resonance. |
| 428 |
|
- fixed bug in sysex handling (patch by Juan Linietsky) |
| 429 |
|
- added global volume attenuation of -9 dB (0.35f) to prevent clipping |
| 430 |
|
which can be overridden with --enable-global-attenuation |
| 431 |
|
- EG fixes: made the length of "attack hold" stage more |
| 432 |
|
accurate. Release stage can now start before attack stage |
| 433 |
|
ends. Cancel release didn't work when sustain was zero. Attack |
| 434 |
|
time now has a minimal value to prevent clicks. |
| 435 |
|
- fixed pitch changes larger than one octave |
| 436 |
|
- fixed EG3 (pitch envelope) synthesis which was neutral all the time |
| 437 |
|
- implemented portamento mode and solo mode (a.k.a 'mono mode'): |
| 438 |
|
all modes can be altered via standard GM messages, that is CC5 for |
| 439 |
|
altering portamento time, CC65 for enabling / disabling portamento |
| 440 |
|
mode, CC126 for enabling solo mode and CC127 for disabling solo mode |
| 441 |
|
- fine tuning of the curves for volume (CC7), pan (CC10 and gig |
| 442 |
|
parameter) and crossfade |
| 443 |
|
- added support for the "attenuation controller threshold" gig |
| 444 |
|
parameter |
| 445 |
|
- added smoothing of volume changes caused by control change |
| 446 |
|
messages |
| 447 |
|
- sample loop parameters are now taken from the DimensionRegion |
| 448 |
|
instead of the wave chunk |
| 449 |
|
- fixed keyswitching for v3 gigs with a number of keyswitch splits |
| 450 |
|
not equal to a power of two |
| 451 |
|
- reimplementation of the filter algorithm. The new filter is more |
| 452 |
|
accurate and supports all gig filter types, including bandreject |
| 453 |
|
and lowpass turbo. |
| 454 |
|
- real support for 24 bit samples - samples are not truncated to |
| 455 |
|
16 bits anymore |
| 456 |
|
- support for aftertouch (channel pressure, not polyphonic |
| 457 |
|
aftertouch) |
| 458 |
|
- LFO1 behaviour fixed (dampening from max volume instead of |
| 459 |
|
amplifying from 0) |
| 460 |
|
|
| 461 |
|
* LSCP server: |
| 462 |
|
- fixed application exit on broken pipe error (fixes bug #20) |
| 463 |
|
- fixed the notification messages delay due to lack of |
| 464 |
|
network activity (fixes bug #26) |
| 465 |
|
- fixed parser bug which occured on space(s) within device parameters |
| 466 |
|
(e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'") |
| 467 |
|
|
| 468 |
|
* audio driver: |
| 469 |
|
- added aRts audio output driver (by no means RT safe) |
| 470 |
|
|
| 471 |
|
* MIDI driver: |
| 472 |
|
- fixed legacy sysex code which caused dispatching of MIDI SysEx |
| 473 |
|
messages several times instead of once |
| 474 |
|
- API extension for MIDI drivers which already supply exact time stamps |
| 475 |
|
for events (i.e. for offline rendering based MIDI drivers) |
| 476 |
|
- added checks for bad MIDI data |
| 477 |
|
|
| 478 |
|
* linuxsampler application: |
| 479 |
|
- show available sampler engine types on startup |
| 480 |
|
|
| 481 |
|
* general changes: |
| 482 |
|
- support for muting sampler channels and solo mode of the same, two new |
| 483 |
|
LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new |
| 484 |
|
fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were |
| 485 |
|
introduced for this, the behavior is the same like on a mixer console |
| 486 |
|
(patch by Grigor Iliev, a bit adjusted). Also added configure option |
| 487 |
|
--enable-process-muted-channels which can be used to enable the |
| 488 |
|
processing of muted channels. |
| 489 |
|
- support for sostenuto pedal |
| 490 |
|
- support for monitoring the total number of active voices |
| 491 |
|
(new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX, |
| 492 |
|
SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT) |
| 493 |
|
- fixed some memory management errors |
| 494 |
|
- fixed some concurrency problems that could lead to crashes when |
| 495 |
|
LSCP commands were executed |
| 496 |
|
- fixed crash when instrument loading failed previously on the same |
| 497 |
|
sampler channel (fixes bug #36) |
| 498 |
|
|
| 499 |
|
Version 0.3.3 (15 July 2005) |
| 500 |
|
|
| 501 |
|
* packaging changes: |
| 502 |
|
- fixed compilation with gcc 4.0 |
| 503 |
|
|
| 504 |
|
* Gigasampler format engine: |
| 505 |
|
- LFO preprocessing was performed even though the respective LFO was |
| 506 |
|
disabled by the instrument patch (minor efficiency fix) |
| 507 |
|
- if period time of chosen audio device is too small (< MIN_RELEASE_TIME) |
| 508 |
|
for volume ramp downs in the same fragment (needed for current voice |
| 509 |
|
stealing implementation) then simply inform the user with a warning |
| 510 |
|
about possible click sounds and reduce the volume ramp down |
| 511 |
|
appropriately instead of cancelling the audio device connection |
| 512 |
|
|
| 513 |
|
Version 0.3.2 (24 June 2005) |
| 514 |
|
|
| 515 |
|
* packaging changes: |
| 516 |
- updated autotools build files to compile on OS X |

- hand-crafted assembly optimization code can be disabled with |
| 519 |
'./configure --disable-asm' (definitely not recommended) |
'./configure --disable-asm' (definitely not recommended) |
| 520 |
* support for the gig parameters for "release velocity response" |
- fixed 'make dist' rule to include all necessary files |
| 521 |
curves |
- require automake (>= 1.5) for 'make -f Makefile.cvs' |
| 522 |
* fine tuning of the EGADSR envelope |
(due to 'dist-bzip2' automake option) |
| 523 |
|
|
| 524 |
|
* Gigasampler format engine: |
| 525 |
|
- support for the gig parameters for "release velocity response" curves |
| 526 |
|
- fine tuning of the EGADSR envelope |
| 527 |
|
- volume of release triggered samples now depends on note-on velocity, |
| 528 |
|
note length and gig parameter "release trigger decay" instead of |
| 529 |
|
note-off velocity. |
| 530 |
|
- revised voice stealing |
| 531 |
|
(fixes crash and endless loop caused by voice stealing) |
| 532 |
|
- don't reset scale tuning on instrument or audio output device change |
| 533 |
|
- handle key group conflicts right at the beginning of each fragment |
| 534 |
|
instead of when the respective voice is actually launched |
| 535 |
|
(fixes undefined behavior if stolen voices belonged to a key group - |
| 536 |
|
this case was followed by a "killed voice survived" error message) |
| 537 |
|
- fixed minor issue with null/silence samples |
| 538 |
|
(those stole voices even though they don't need a voice at all which |
| 539 |
|
resulted in "voice stealing didn't work out" messages) |
| 540 |
|
- don't reset volume, pan, pitch and MIDI controller values on |
| 541 |
|
instrument or audio output device change |
| 542 |
|
|
| 543 |
|
* LSCP server: |
| 544 |
|
- fixed some crashes (patch by Grigor Iliev, fixes #19) |
| 545 |
|
- fixed LSCP event "CHANNEL_INFO" notification |
| 546 |
|
(e.g. did not notify on volume changes or MIDI program change events) |
| 547 |
|
|
| 548 |
|
* linuxsampler application: |
| 549 |
|
- added command line parameters --lscp-addr and --lscp-port to override |
| 550 |
|
default IP address and port of LSCP server |
| 551 |
