Version 0.5.0 (15 October 2007) |
| 24 |
|
|
| 25 |
|
* packaging changes: |
| 26 |
|
- config.h is not going to be installed along with liblinuxsampler's |
| 27 |
|
API header files anymore |
| 28 |
|
- only the API relevant header (and source) files will be exported to |
| 29 |
|
the Doxygen API documentation (explicitly listed in Doxyfile.in) |
| 30 |
|
- added completely new XCode project files for Mac OSX which is now |
| 31 |
|
capable to execute our autoconf environment, thus no need anymore |
| 32 |
|
to maintain the compile time configuration file (osx/version.h) for |
| 33 |
|
OSX manually (patch by Toshi Nagata) |
| 34 |
|
- fixed buggy boolean --enable-foo / --disable-foo configure script |
| 35 |
|
parameters |
| 36 |
|
- global.h now only covers global definitions that are needed for the |
| 37 |
|
C++ API header files, all implementation internal global definitions |
| 38 |
|
are now in global_private.h |
| 39 |
|
- atomic.h is not exposed to the C++ API anymore |
| 40 |
|
- no need to include config.h anymore for using LS's API header files |
| 41 |
|
- fixed warnings in API doc generation |
| 42 |
|
|
| 43 |
|
* general changes: |
| 44 |
|
- replaced the old, confusing MIDI program change mechanism by a |
| 45 |
|
flexible MIDI instrument mapper which allows to map arbitrary |
| 46 |
|
(MIDI bank, MIDI program) pairs with arbitrary |
| 47 |
|
(engine type, instrument file, file index) triplets which will be |
| 48 |
|
loaded on the respective channel when such MIDI program change |
| 49 |
|
messages arrive, beside that, each entry allows to define a life-time |
| 50 |
|
strategy for the instrument, so the user can define whether the |
| 51 |
|
instrument should i.e. be permanently loaded (to be able to switch |
| 52 |
|
quickly among sounds) or i.e. loaded just on demand when the |
| 53 |
|
respective program change arrives (to safe RAM space), as well as a |
| 54 |
|
global volume factor for each entry, so the user can adjust the volume |
| 55 |
|
dynamic of his mapped instrument collection without having to modify |
| 56 |
|
the instrument files, also one can manage arbitrary amount of such |
| 57 |
|
MIDI instrument maps and assign each sampler channel individually |
| 58 |
|
a certain map, so that i.e. separation of normal instruments and |
| 59 |
|
drumkits is possible |
| 60 |
|
- new notification events for tracking changes to audio/MIDI devices, |
| 61 |
|
MIDI instrument maps, MIDI instruments, FX sends, global volume. |
| 62 |
|
- sampler was limited to load max. 200 instruments in the background |
| 63 |
|
due to a constant size RingBuffer FIFO which is now replaced by a |
| 64 |
|
dynamic (unlimited) size std::list FIFO |
| 65 |
|
- added FX sends, these allow to route audio signals to arbitrary audio |
| 66 |
|
output channels for being processed by external effect processors |
| 67 |
|
(i.e. jack-rack), the send levels are controllable via arbitrary MIDI |
| 68 |
|
controllers |
| 69 |
|
- global (sampler wide) volume can now be controlled at runtime |
| 70 |
|
- Implemented new, improved notification system |
| 71 |
|
- fixed compilation errors regarding OSX |
| 72 |
|
(patch by Toshi Nagata) |
| 73 |
|
- implemented instruments database |
| 74 |
|
- added support for escape sequences to the instruments database |
| 75 |
|
- added highly experimental support for on-the-fly instrument editing |
| 76 |
|
within the sampler's process (by using instrument editor plugins), |
| 77 |
|
you'll notice the new "Registered instrument editors:" message on |
| 78 |
|
startup, added a new LSCP command: |
| 79 |
|
"EDIT CHANNEL INSTRUMENT <sampler-channel>" |
| 80 |
|
to spawn a matching instrument editor for the instrument on the |
| 81 |
|
given sampler channel, the plugin path can be overridden at compile |
| 82 |
|
time with ./configure --enable-plugin-dir=/some/dir |
| 83 |
|
- added experimental code for synchronizing instrument editors hosted |
| 84 |
|
in the sampler's process to safely edit instruments while playing |
| 85 |
|
without a crash (hopefully) by either suspending single regions |
| 86 |
|
wherever possible or if unavoidable whole engine(s) |
| 87 |
|
- fixed several issues in fundamental "Thread" class: set scheduling |
| 88 |
|
policy and priority on thread level, set a minimum stack size for |
| 89 |
|
thread (TODO: a reasonable value yet to be tested), bugfix: non-RT |
| 90 |
|
threads simply inherited properties of starting thread instead of |
| 91 |
|
setting their own policy and priority |
| 92 |
|
- minor fix in our automatic stack trace mechanism on crashes, the |
| 93 |
|
main process did not wait for the stack trace process to finish |
| 94 |
|
its output |
| 95 |
|
- fixed some minor memory leaks |
| 96 |
|
- reenabled assembly features support, at the moment only for |
| 97 |
|
enabling a fast denormal FPU mode (x86 platforms supporting SSE2) |
| 98 |
|
- minor assembly fix in x86 features detection (don't use the PIC |
| 99 |
|
register, to avoid relocations in the text segment at runtime) |
| 100 |
|
- POSIX callback functions of Thread.h are hidden |
| 101 |
|
|
| 102 |
|
* MIDI driver: |
| 103 |
|
- dispatch bank select (MSB and LSB) messages |
| 104 |
|
|
| 105 |
|
* audio driver: |
| 106 |
|
- the ALSA audio output driver parameters now reflect the correct |
| 107 |
|
parameter value ranges for the respective selected sound card |
| 108 |
|
(patch by Till Wimmer, a bit fixed and extended) |
| 109 |
|
|
| 110 |
|
* Gigasampler format engine: |
| 111 |
|
- if a filter is used and EG2 finishes before EG1, let the voice |
| 112 |
|
die when EG2 has finished (this fixes a problem with clicks and |
| 113 |
|
voice starvation for some gigs) |
| 114 |
|
- playback is no longer disabled during instrument loading |
| 115 |
|
- all notes playing on a channel that changes its instrument keep |
| 116 |
|
playing with the old instrument until they get a note off |
| 117 |
|
command |
| 118 |
|
- EG fix: a release value of zero could cause noises or crash |
| 119 |
|
- handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB) |
| 120 |
|
- EG fine tuning: when attack is zero the EG starts at a level |
| 121 |
|
above max sustain level, which means that there is a decay phase |
| 122 |
|
even if sustain is 100% |
| 123 |
|
- more EG fixes: the level could sometimes go below zero and cause |
| 124 |
|
noises or crashes |
| 125 |
|
- minor fix of EGDecay (patch by Toshi Nagata) |
| 126 |
|
- fixed compiler error when --enable-override-filter-type was |
| 127 |
|
supplied to the configure script (fixes #46) |
| 128 |
|
- disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS |
| 129 |
|
instead of a fix value |
| 130 |
|
- behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode), |
| 131 |
|
127 (solo mode) only kill voices if the respective mode really |
| 132 |
|
changed |
| 133 |
|
|
| 134 |
|
* LSCP server: |
| 135 |
|
- fixed compile time error for old Bison versions |
| 136 |
|
(i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata) |
| 137 |
|
- parser now supports extended ASCII character set |
| 138 |
|
(up to ASCII code 255, i.e. includes now umlauts and accents) |
| 139 |
|
- filename arguments in LSCP commands now allow to use escape |
| 140 |
|
sequences, that is directly literal as one of: \', \", \\, \n, \r, |
| 141 |
|
\f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII |
| 142 |
|
code value like \xf2) (fixes bug #24) |
| 143 |
|
- the following LSCP commands now also support escape sequences for at |
| 144 |
|
least one of their text-based parameters (i.e. name, description): |
| 145 |
|
"ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT", |
| 146 |
|
"SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND", |
| 147 |
|
"SET DB_INSTRUMENT_DIRECTORY NAME", |
| 148 |
|
"SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME", |
| 149 |
|
"SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS", |
| 150 |
|
"FIND DB_INSTRUMENT_DIRECTORIES" |
| 151 |
|
- returns verbose syntax errors (line and column where syntax error |
| 152 |
|
occured, the unexpected character and the actually expected, possible |
| 153 |
|
character(s), the latter only if less than 5 possibilities) |
| 154 |
|
- made sure that LSCP syntax is not affected by gigedit locale |
| 155 |
|
settings |
| 156 |
|
- bugfix regarding strings parameter lists: all comma separated lists |
| 157 |
|
of strings were treated as being one string containing commas |
| 158 |
|
(fixes #57) |
| 159 |
|
|
| 160 |
|
* Bug fixes: |
| 161 |
|
- fixed crash occurring on certain LSCP scripts (Bug 39) |
| 162 |
|
- another thread safety fix for lscp "load engine" and "set |
| 163 |
|
channel audio output device" |
| 164 |
|
- fixed a crash which occurs when reassigning the same engine |
| 165 |
|
on a sampler channel with connected MIDI device |
| 166 |
|
- fixed a crash which occurs when changing the number of ports of a MIDI |
| 167 |
|
device connected to a sampler channel to number less then or equal |
| 168 |
|
to the index of the port to which the sampler channel is connected. |
| 169 |
|
- The previous bindings were not been disconnected when altering |
| 170 |
|
the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for |
| 171 |
|
unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE). |
| 172 |
|
- The active stream/voice count statistic was incorrect. |
| 173 |
|
- notification events were not been sent for some sampler |
| 174 |
|
channel changes |
| 175 |
|
- added default min and max values to restrict the number of allowed |
| 176 |
|
audio output channels and MIDI input ports |
| 177 |
|
- the connection to the PCM interface is now closed when destroying |
| 178 |
|
an audio output device |
| 179 |
|
- files with slash in their path or filename could not be loaded |
| 180 |
|
|
| 181 |
|
* test cases: |
| 182 |
|
- updated and fixed (haven't been touched in a while) |
| 183 |
|
|
| 184 |
|
Version 0.4.0 (24 November 2006) |
| 185 |
|
|
| 186 |
|
* packaging changes: |
| 187 |
|
- changed deprecated copyright attribute to license; added ldconfig |
| 188 |
|
to post-(un)install steps; added devel package for liblinuxsampler; |
| 189 |
|
to linuxsampler.spec (RPM) |
| 190 |
|
- install necessary development header files for allowing 3rd party |
| 191 |
|
applications to link against liblinuxsampler |
| 192 |
|
- liblinuxsampler's API documentation can be generated with 'make docs' |
| 193 |
|
(Doxygen required) |
| 194 |
|
- added benchmark to automatically detect the best triangle LFO |
| 195 |
|
implementation (currently either an integer math solution or a |
| 196 |
|
di-harmonic approximation), automatic detection can be overriden |
| 197 |
|
with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x |
| 198 |
|
configure script argument though (mandatory for cross-compilation) |
| 199 |
|
- do not automatically pick optimized gcc flags if the user already |
| 200 |
|
provided some on his own (as CXXFLAGS) |
| 201 |
|
- added compile time option to disable processing of All-Notes-Off MIDI |
| 202 |
|
messages |
| 203 |
|
- added compile time options to allow disabling the various audio and |
| 204 |
|
MIDI drivers |
| 205 |
|
- fixed automatic GCC CPU switch detection on PPC |
| 206 |
|
(patch by Ebrahim Mayat) |
| 207 |
|
|
| 208 |
|
* Gigasampler format engine: |
| 209 |
|
- extensive synthesis optimization |
| 210 |
|
(reimplementation of EGs and LFO(s), removed synthesis parameter |
| 211 |
|
prerendering and the synthesis parameter matrix in general, splitting |
| 212 |
|
each audio fragment into subfragments now where each subfragment uses |
| 213 |
|
constant pitch and filter coefficients. The volume coefficient is |
| 214 |
|
linearly interpolated inside a subfragment, unless |
| 215 |
|
--disable-interpolate-volume is set.) |
| 216 |
|
- fine tuning of the EG modulation parameters |
| 217 |
|
- improved filter cutoff calculation by adding support for the |
| 218 |
|
following gig parameters: Cutoff freq (used when no cutoff |
| 219 |
|
controller is defined), Control invert, Minimum cutoff, Velocity |
| 220 |
|
curve and Velocity range. The keyboard tracking now scales |
| 221 |
|
cutoff frequency instead of resonance. |
| 222 |
|
- added support for gig parameter Resonance. |
| 223 |
|
- fixed bug in sysex handling (patch by Juan Linietsky) |
| 224 |
|
- added global volume attenuation of -9 dB (0.35f) to prevent clipping |
| 225 |
|
which can be overridden with --enable-global-attenuation |
| 226 |
|
- EG fixes: made the length of "attack hold" stage more |
| 227 |
|
accurate. Release stage can now start before attack stage |
| 228 |
|
ends. Cancel release didn't work when sustain was zero. Attack |
| 229 |
|
time now has a minimal value to prevent clicks. |
| 230 |
|
- fixed pitch changes larger than one octave |
| 231 |
|
- fixed EG3 (pitch envelope) synthesis which was neutral all the time |
| 232 |
|
- implemented portamento mode and solo mode (a.k.a 'mono mode'): |
| 233 |
|
all modes can be altered via standard GM messages, that is CC5 for |
| 234 |
|
altering portamento time, CC65 for enabling / disabling portamento |
| 235 |
|
mode, CC126 for enabling solo mode and CC127 for disabling solo mode |
| 236 |
|
- fine tuning of the curves for volume (CC7), pan (CC10 and gig |
| 237 |
|
parameter) and crossfade |
| 238 |
|
- added support for the "attenuation controller threshold" gig |
| 239 |
|
parameter |
| 240 |
|
- added smoothing of volume changes caused by control change |
| 241 |
|
messages |
| 242 |
|
- sample loop parameters are now taken from the DimensionRegion |
| 243 |
|
instead of the wave chunk |
| 244 |
|
- fixed keyswitching for v3 gigs with a number of keyswitch splits |
| 245 |
|
not equal to a power of two |
| 246 |
|
- reimplementation of the filter algorithm. The new filter is more |
| 247 |
|
accurate and supports all gig filter types, including bandreject |
| 248 |
|
and lowpass turbo. |
| 249 |
|
- real support for 24 bit samples - samples are not truncated to |
| 250 |
|
16 bits anymore |
| 251 |
|
- support for aftertouch (channel pressure, not polyphonic |
| 252 |
|
aftertouch) |
| 253 |
|
- LFO1 behaviour fixed (dampening from max volume instead of |
| 254 |
|
amplifying from 0) |
| 255 |
|
|
| 256 |
|
* LSCP server: |
| 257 |
|
- fixed application exit on broken pipe error (fixes bug #20) |
| 258 |
|
- fixed the notification messages delay due to lack of |
| 259 |
|
network activity (fixes bug #26) |
| 260 |
|
- fixed parser bug which occured on space(s) within device parameters |
| 261 |
|
(e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'") |
| 262 |
|
|
| 263 |
|
* audio driver: |
| 264 |
|
- added aRts audio output driver (by no means RT safe) |
| 265 |
|
|
| 266 |
|
* MIDI driver: |
| 267 |
|
- fixed legacy sysex code which caused dispatching of MIDI SysEx |
| 268 |
|
messages several times instead of once |
| 269 |
|
- API extension for MIDI drivers which already supply exact time stamps |
| 270 |
|
for events (i.e. for offline rendering based MIDI drivers) |
| 271 |
|
- added checks for bad MIDI data |
| 272 |
|
|
| 273 |
|
* linuxsampler application: |
| 274 |
|
- show available sampler engine types on startup |
| 275 |
|
|
| 276 |
|
* general changes: |
| 277 |
|
- support for muting sampler channels and solo mode of the same, two new |
| 278 |
|
LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new |
| 279 |
|
fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were |
| 280 |
|
introduced for this, the behavior is the same like on a mixer console |
| 281 |
|
(patch by Grigor Iliev, a bit adjusted). Also added configure option |
| 282 |
|
--enable-process-muted-channels which can be used to enable the |
| 283 |
|
processing of muted channels. |
| 284 |
|
- support for sostenuto pedal |
| 285 |
|
- support for monitoring the total number of active voices |
| 286 |
|
(new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX, |
| 287 |
|
SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT) |
| 288 |
|
- fixed some memory management errors |
| 289 |
|
- fixed some concurrency problems that could lead to crashes when |
| 290 |
|
LSCP commands were executed |
| 291 |
|
- fixed crash when instrument loading failed previously on the same |
| 292 |
|
sampler channel (fixes bug #36) |
| 293 |
|
|

|
* Gigasampler format engine: |
| 300 |
|
- LFO preprocessing was performed even though the respective LFO was |
| 301 |
|
disabled by the instrument patch (minor efficiency fix) |
| 302 |
|
- if period time of chosen audio device is too small (< MIN_RELEASE_TIME) |
| 303 |
|
for volume ramp downs in the same fragment (needed for current voice |
| 304 |
|
stealing implementation) then simply inform the user with a warning |
| 305 |
|
about possible click sounds and reduce the volume ramp down |
| 306 |
|
appropriately instead of cancelling the audio device connection |
| 307 |
