Version CVS HEAD (?) |
| 2 |
|
|
| 3 |
|
* packaging changes: |
| 4 |
|
- 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 |
|
|
| 10 |
|
* general changes: |
| 11 |
|
- bugfix: on some POSIX systems instrument editor plugins refused to |
| 12 |
|
load as we used a non-portable Linux specific struct field |
| 13 |
|
(fixes bug #70, patch by Ronald Baljeu) |
| 14 |
|
- fixed endless loop which occured when loading an instrument editor |
| 15 |
|
plugin DLL on Windows systems failed |
| 16 |
|
- fixed memory leaks that occurred when liblinuxsampler was unloaded |
| 17 |
|
- optimized the SynchronizedConfig class so it doesn't wait |
| 18 |
|
unnecessarily long after an update |
| 19 |
|
- added support for notifying instrument editors on note-on / note-off |
| 20 |
|
events (e.g. to highlight the pressed keys on the virtual keyboard |
| 21 |
|
of gigedit) |
| 22 |
|
- added support for triggering notes by instrument editors (see above) |
| 23 |
|
- be verbose on DLL load errors (on Linux) |
| 24 |
|
- fixed di-harmonic triangle LFO implementation (this LFO implementation |
| 25 |
|
is only used by very few systems, most pick the int math |
| 26 |
|
implementation, which is usually faster) |
| 27 |
|
- fixes for audio drivers with varying buffer sizes |
| 28 |
|
|
| 29 |
|
* audio driver: |
| 30 |
|
- removed the nonsense audio channel constraint (which was hard coded to |
| 31 |
|
max. 100 audio channels) for most audio drivers |
| 32 |
|
- JACK audio driver did not offer a device parameter "SAMPLERATE" as |
| 33 |
|
opposed to the LSCP specs |
| 34 |
|
- bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK) |
| 35 |
|
reflected the wrong value |
| 36 |
|
- fixed a memory management bug in ASIO driver |
| 37 |
|
- Makefile fix: JACK_CFLAGS wasn't used |
| 38 |
|
- JACK: use jack_client_open instead of thedeprecated |
| 39 |
|
jack_client_new |
| 40 |
|
|
| 41 |
|
* MIDI driver: |
| 42 |
|
- added JACK MIDI driver |
| 43 |
|
- dispatch bank select as ordinary CC as well, the user might seriously |
| 44 |
|
want to (mis)use it for some purpose ("fixed" in all current MIDI |
| 45 |
|
input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME) |
| 46 |
|
|
| 47 |
|
* instruments database: |
| 48 |
|
- avoid time consuming samples scanning when adding instruments |
| 49 |
|
to the instruments database |
| 50 |
|
- added support for handling lost files in the instruments database |
| 51 |
|
|
| 52 |
|
* Gigasampler format engine: |
| 53 |
|
- fixed a memory leak that could happen when a channel was deleted |
| 54 |
|
while notes were playing |
| 55 |
|
- made it possible to load an instrument even if the audio thread |
| 56 |
|
isn't running |
| 57 |
|
- added partial support for the "Controller Triggered" MIDI rule, |
| 58 |
|
enough for piano gigs with pedal noise samples |
| 59 |
|
- minor fix: only mark FX sends as being modified if really the |
| 60 |
|
respective FX send MIDI controller was used |
| 61 |
|
- added support for GM global device volume SysEx message |
| 62 |
|
(can be selected at compile time to either apply globally to the |
| 63 |
|
whole sampler [default] or only to the sampler channels that are |
| 64 |
|
connected to the respective MIDI input port the SysEx message arrived |
| 65 |
|
on) |
| 66 |
|
- bugfix: notes triggered at position 0 in the audio buffer were |
| 67 |
|
sometimes wrongly killed in the same buffer, causing no sound to |
| 68 |
|
be played |
| 69 |
|
- added support for chromatic / drumkit mode Roland GS Sysex message |
| 70 |
|
which is usally used to switch a part between chromatic sounds and |
| 71 |
|
drumkit sounds (as opposed to their common default setting of MIDI |
| 72 |
|
part 10 being a drumkit part and all other ones chromatic parts), in |
| 73 |
|
LS however one can switch between the first 16 MIDI instrument maps |
| 74 |
|
defined for the sampler |
| 75 |
|
|
| 76 |
|
* LSCP server: |
| 77 |
|
- added new LSCP event "CHANNEL_MIDI" which can be used by frontends to |
| 78 |
|
react on MIDI data arriving on certain sampler channels (so far only |
| 79 |
|
Note-On and Note-Off events are sent via this LSCP event) |
| 80 |
|
- added new LSCP event "DEVICE_MIDI" which can be used by frontends to |
| 81 |
|
react on MIDI data arriving on certain MIDI input devices (so far only |
| 82 |
|
Note-On and Note-Off events are sent via this LSCP event) |
| 83 |
|
- added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and |
| 84 |
|
SET DB_INSTRUMENT FILE_PATH |
| 85 |
|
- bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications |
| 86 |
|
was incorrect |
| 87 |
|
- Optimized the retrieval of the MIDI instrument mappings |
| 88 |
|
|
| 89 |
|
* Bug fixes: |
| 90 |
|
- fixed a crash which occurs when removing a sampler channel waiting |
| 91 |
|
to start instrument loading after another channel |
| 92 |
|
|
| 93 |
|
|
| 94 |
|
Version 0.5.1 (6 December 2007) |
| 95 |
|
|
| 96 |
|
* packaging changes: |
| 97 |
|
- added autoconf checks for pthread library |
| 98 |
|
- added autoconf check for pthread bug found on certain NPTL-enabled |
| 99 |
|
glibc versions (see Gentoo bug report #194076) |
| 100 |
|
- added autoconf checks for MS Windows |
| 101 |
|
|
| 102 |
|
* general changes: |
| 103 |
|
- bugfix: the thread used by an editor plugin didn't die when the |
| 104 |
|
editor closed |
| 105 |
|
- bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero |
| 106 |
|
out all the space. operator--() did not apply size_mask after |
| 107 |
|
decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in |
| 108 |
|
order to avoid problems with the _NonVolatileReader functions. |
| 109 |
|
- bugfix: Stream.h: added a missing divide by BytesPerSample in |
| 110 |
|
GetWriteSpace(). Since this function is currently only used in |
| 111 |
|
the stream's qsort() compare function, it didn't trigger any |
| 112 |
|
bugs. |
| 113 |
|
- Resampler.h, Synthesizer.h: cubic interpolation now works in |
| 114 |
|
24bit mode too. Faster method to read 24bit words on little |
| 115 |
|
endian machines (x86): replaced 3 byte reads + shifts with a 1 |
| 116 |
|
unaligned 32bit read and shift |
| 117 |
|
- experimental support for MS Windows (MIDI input via MME, AUDIO |
| 118 |
|
output via ASIO) |
| 119 |
|
- made handling of SIGINT signal (Ctrl-C) a bit more robust |
| 120 |
|
- support for monitoring the total number of active disk streams |
| 121 |
|
(new LSCP commands: GET TOTAL_STREAM_COUNT, |
| 122 |
|
SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT) |
| 123 |
|
|
| 124 |
|
* AUDIO driver: |
| 125 |
|
- added Windows ASIO low latency audio driver |
| 126 |
|
|
| 127 |
|
* MIDI driver: |
| 128 |
|
- added MME Windows MIDI driver |
| 129 |
|
|
| 130 |
|
* LSCP server: |
| 131 |
|
- added support for Windows style path / filenames, however with |
| 132 |
|
forward slash path separators instead of backslash |
| 133 |
|
(i.e. "C:/foo/bar.gig") |
| 134 |
|
- allow naughty liblscp to send non-string device parameters within |
| 135 |
|
apostrophes as well |
| 136 |
|
- added new LSCP commands: "GET FILE INSTRUMENTS <file>", |
| 137 |
|
"LIST FILE INSTRUMENTS <file>" and |
| 138 |
|
"GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations |
| 139 |
|
about an arbitrary instrument file on the system where the sampler is |
| 140 |
|
running on |
| 141 |
|
|
| 142 |
|
Version 0.5.0 (15 October 2007) |
| 143 |
|
|
| 144 |
|
* packaging changes: |
| 145 |
|
- config.h is not going to be installed along with liblinuxsampler's |
| 146 |
|
API header files anymore |
| 147 |
|
- only the API relevant header (and source) files will be exported to |
| 148 |
|
the Doxygen API documentation (explicitly listed in Doxyfile.in) |
| 149 |
|
- added completely new XCode project files for Mac OSX which is now |
| 150 |
|
capable to execute our autoconf environment, thus no need anymore |
| 151 |
|
to maintain the compile time configuration file (osx/version.h) for |
| 152 |
|
OSX manually (patch by Toshi Nagata) |
| 153 |
|
- fixed buggy boolean --enable-foo / --disable-foo configure script |
| 154 |
|
parameters |
| 155 |
|
- global.h now only covers global definitions that are needed for the |
| 156 |
|
C++ API header files, all implementation internal global definitions |
| 157 |
|
are now in global_private.h |
| 158 |
|
- atomic.h is not exposed to the C++ API anymore |
| 159 |
|
- no need to include config.h anymore for using LS's API header files |
| 160 |
|
- fixed warnings in API doc generation |
| 161 |
|
|
| 162 |
|
* general changes: |
| 163 |
|
- replaced the old, confusing MIDI program change mechanism by a |
| 164 |
|
flexible MIDI instrument mapper which allows to map arbitrary |
| 165 |
|
(MIDI bank, MIDI program) pairs with arbitrary |
| 166 |
|
(engine type, instrument file, file index) triplets which will be |
| 167 |
|
loaded on the respective channel when such MIDI program change |
| 168 |
|
messages arrive, beside that, each entry allows to define a life-time |
| 169 |
|
strategy for the instrument, so the user can define whether the |
| 170 |
|
instrument should i.e. be permanently loaded (to be able to switch |
| 171 |
|
quickly among sounds) or i.e. loaded just on demand when the |
| 172 |
|
respective program change arrives (to safe RAM space), as well as a |
| 173 |
|
global volume factor for each entry, so the user can adjust the volume |
| 174 |
|
dynamic of his mapped instrument collection without having to modify |
| 175 |
|
the instrument files, also one can manage arbitrary amount of such |
| 176 |
|
MIDI instrument maps and assign each sampler channel individually |
| 177 |
|
a certain map, so that i.e. separation of normal instruments and |
| 178 |
|
drumkits is possible |
| 179 |
|
- new notification events for tracking changes to audio/MIDI devices, |
| 180 |
|
MIDI instrument maps, MIDI instruments, FX sends, global volume. |
| 181 |
|
- sampler was limited to load max. 200 instruments in the background |
| 182 |
|
due to a constant size RingBuffer FIFO which is now replaced by a |
| 183 |
|
dynamic (unlimited) size std::list FIFO |
| 184 |
|
- added FX sends, these allow to route audio signals to arbitrary audio |
| 185 |
|
output channels for being processed by external effect processors |
| 186 |
|
(i.e. jack-rack), the send levels are controllable via arbitrary MIDI |
| 187 |
|
controllers |
| 188 |
|
- global (sampler wide) volume can now be controlled at runtime |
| 189 |
|
- Implemented new, improved notification system |
| 190 |
|
- fixed compilation errors regarding OSX |
| 191 |
|
(patch by Toshi Nagata) |
| 192 |
|
- implemented instruments database |
| 193 |
|
- added support for escape sequences to the instruments database |
| 194 |
|
- added highly experimental support for on-the-fly instrument editing |
| 195 |
|
within the sampler's process (by using instrument editor plugins), |
| 196 |
|
you'll notice the new "Registered instrument editors:" message on |
| 197 |
|
startup, added a new LSCP command: |
| 198 |
|
"EDIT CHANNEL INSTRUMENT <sampler-channel>" |
| 199 |
|
to spawn a matching instrument editor for the instrument on the |
| 200 |
|
given sampler channel, the plugin path can be overridden at compile |
| 201 |
|
time with ./configure --enable-plugin-dir=/some/dir |
| 202 |
|
- added experimental code for synchronizing instrument editors hosted |
| 203 |
|
in the sampler's process to safely edit instruments while playing |
| 204 |
|
without a crash (hopefully) by either suspending single regions |
| 205 |
|
wherever possible or if unavoidable whole engine(s) |
| 206 |
|
- fixed several issues in fundamental "Thread" class: set scheduling |
| 207 |
|
policy and priority on thread level, set a minimum stack size for |
| 208 |
|
thread (TODO: a reasonable value yet to be tested), bugfix: non-RT |
| 209 |
|
threads simply inherited properties of starting thread instead of |
| 210 |
|
setting their own policy and priority |
| 211 |
|
- minor fix in our automatic stack trace mechanism on crashes, the |
| 212 |
|
main process did not wait for the stack trace process to finish |
| 213 |
|
its output |
| 214 |
|
- fixed some minor memory leaks |
| 215 |
|
- reenabled assembly features support, at the moment only for |
| 216 |
|
enabling a fast denormal FPU mode (x86 platforms supporting SSE2) |
| 217 |
|
- minor assembly fix in x86 features detection (don't use the PIC |
| 218 |
|
register, to avoid relocations in the text segment at runtime) |
| 219 |
|
- POSIX callback functions of Thread.h are hidden |
| 220 |
|
|
| 221 |
|
* MIDI driver: |
| 222 |
|
- dispatch bank select (MSB and LSB) messages |
| 223 |
|
|
| 224 |
|
* audio driver: |
| 225 |
|
- the ALSA audio output driver parameters now reflect the correct |
| 226 |
|
parameter value ranges for the respective selected sound card |
| 227 |
|
(patch by Till Wimmer, a bit fixed and extended) |
| 228 |
|
|
| 229 |
|
* Gigasampler format engine: |
| 230 |
|
- if a filter is used and EG2 finishes before EG1, let the voice |
| 231 |
|
die when EG2 has finished (this fixes a problem with clicks and |
| 232 |
|
voice starvation for some gigs) |
| 233 |
|
- playback is no longer disabled during instrument loading |
| 234 |
|
- all notes playing on a channel that changes its instrument keep |
| 235 |
|
playing with the old instrument until they get a note off |
| 236 |
|
command |
| 237 |
|
- EG fix: a release value of zero could cause noises or crash |
| 238 |
|
- handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB) |
| 239 |
|
- EG fine tuning: when attack is zero the EG starts at a level |
| 240 |
|
above max sustain level, which means that there is a decay phase |
| 241 |
|
even if sustain is 100% |
| 242 |
|
- more EG fixes: the level could sometimes go below zero and cause |
| 243 |
|
noises or crashes |
| 244 |
|
- minor fix of EGDecay (patch by Toshi Nagata) |
| 245 |
|
- fixed compiler error when --enable-override-filter-type was |
| 246 |
|
supplied to the configure script (fixes #46) |
| 247 |
|
- disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS |
| 248 |
|
instead of a fix value |
| 249 |
|
- behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode), |
| 250 |
|
127 (solo mode) only kill voices if the respective mode really |
| 251 |
|
changed |
| 252 |
|
|
| 253 |
|
* LSCP server: |
| 254 |
|
- fixed compile time error for old Bison versions |
| 255 |
|
(i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata) |
| 256 |
|
- parser now supports extended ASCII character set |
| 257 |
|
(up to ASCII code 255, i.e. includes now umlauts and accents) |
| 258 |
|
- filename arguments in LSCP commands now allow to use escape |
| 259 |
|
sequences, that is directly literal as one of: \', \", \\, \n, \r, |
| 260 |
|
\f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII |
| 261 |
|
code value like \xf2) (fixes bug #24) |
| 262 |
|
- the following LSCP commands now also support escape sequences for at |
| 263 |
|
least one of their text-based parameters (i.e. name, description): |
| 264 |
|
"ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT", |
| 265 |
|
"SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND", |
| 266 |
|
"SET DB_INSTRUMENT_DIRECTORY NAME", |
| 267 |
|
"SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME", |
| 268 |
|
"SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS", |
| 269 |
|
"FIND DB_INSTRUMENT_DIRECTORIES" |
| 270 |
|
- returns verbose syntax errors (line and column where syntax error |
| 271 |
|
occured, the unexpected character and the actually expected, possible |
| 272 |
|
character(s), the latter only if less than 5 possibilities) |
| 273 |
|
- made sure that LSCP syntax is not affected by gigedit locale |
| 274 |
|
settings |
| 275 |
|
- bugfix regarding strings parameter lists: all comma separated lists |
| 276 |
|
of strings were treated as being one string containing commas |
| 277 |
|
(fixes #57) |
| 278 |
|
|
| 279 |
|
* Bug fixes: |
| 280 |
|
- fixed crash occurring on certain LSCP scripts (Bug 39) |
| 281 |
|
- another thread safety fix for lscp "load engine" and "set |
| 282 |
|
channel audio output device" |
| 283 |
|
- fixed a crash which occurs when reassigning the same engine |
| 284 |
|
on a sampler channel with connected MIDI device |
| 285 |
|
- fixed a crash which occurs when changing the number of ports of a MIDI |
| 286 |
|
device connected to a sampler channel to number less then or equal |
| 287 |
|
to the index of the port to which the sampler channel is connected. |
| 288 |
|
- The previous bindings were not been disconnected when altering |
| 289 |
|
the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for |
| 290 |
|
unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE). |
| 291 |
|
- The active stream/voice count statistic was incorrect. |
| 292 |
|
- notification events were not been sent for some sampler |
| 293 |
|
channel changes |
| 294 |
|
- added default min and max values to restrict the number of allowed |
| 295 |
|
audio output channels and MIDI input ports |
| 296 |
|
- the connection to the PCM interface is now closed when destroying |
| 297 |
|
an audio output device |
| 298 |
|
- files with slash in their path or filename could not be loaded |
| 299 |
|
|
| 300 |
|
* test cases: |
| 301 |
|
- updated and fixed (haven't been touched in a while) |
| 302 |
