Version CVS HEAD (?) |
2 |
|
3 |
* audio driver: |
4 |
- removed the nonsense audio channel constraint (which was hard coded to |
5 |
max. 100 audio channels) for most audio drivers |
6 |
|
7 |
Version 0.5.1 (6 December 2007) |
8 |
|
9 |
* packaging changes: |
10 |
- added autoconf checks for pthread library |
11 |
- added autoconf check for pthread bug found on certain NPTL-enabled |
12 |
glibc versions (see Gentoo bug report #194076) |
13 |
- added autoconf checks for MS Windows |
14 |
|
15 |
* general changes: |
16 |
- bugfix: the thread used by an editor plugin didn't die when the |
17 |
editor closed |
18 |
- bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero |
19 |
out all the space. operator--() did not apply size_mask after |
20 |
decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in |
21 |
order to avoid problems with the _NonVolatileReader functions. |
22 |
- bugfix: Stream.h: added a missing divide by BytesPerSample in |
23 |
GetWriteSpace(). Since this function is currently only used in |
24 |
the stream's qsort() compare function, it didn't trigger any |
25 |
bugs. |
26 |
- Resampler.h, Synthesizer.h: cubic interpolation now works in |
27 |
24bit mode too. Faster method to read 24bit words on little |
28 |
endian machines (x86): replaced 3 byte reads + shifts with a 1 |
29 |
unaligned 32bit read and shift |
30 |
- experimental support for MS Windows (MIDI input via MME, AUDIO |
31 |
output via ASIO) |
32 |
- made handling of SIGINT signal (Ctrl-C) a bit more robust |
33 |
- support for monitoring the total number of active disk streams |
34 |
(new LSCP commands: GET TOTAL_STREAM_COUNT, |
35 |
SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT) |
36 |
|
37 |
* AUDIO driver: |
38 |
- added Windows ASIO low latency audio driver |
39 |
|
40 |
* MIDI driver: |
41 |
- added MME Windows MIDI driver |
42 |
|
43 |
* LSCP server: |
44 |
- added support for Windows style path / filenames, however with |
45 |
forward slash path separators instead of backslash |
46 |
(i.e. "C:/foo/bar.gig") |
47 |
- allow naughty liblscp to send non-string device parameters within |
48 |
apostrophes as well |
49 |
- added new LSCP commands: "GET FILE INSTRUMENTS <file>", |
50 |
"LIST FILE INSTRUMENTS <file>" and |
51 |
"GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations |
52 |
about an arbitrary instrument file on the system where the sampler is |
53 |
running on |
54 |
|
55 |
Version 0.5.0 (15 October 2007) |
56 |
|
57 |
* packaging changes: |
58 |
- config.h is not going to be installed along with liblinuxsampler's |
59 |
API header files anymore |
60 |
- only the API relevant header (and source) files will be exported to |
61 |
the Doxygen API documentation (explicitly listed in Doxyfile.in) |
62 |
- added completely new XCode project files for Mac OSX which is now |
63 |
capable to execute our autoconf environment, thus no need anymore |
64 |
to maintain the compile time configuration file (osx/version.h) for |
65 |
OSX manually (patch by Toshi Nagata) |
66 |
- fixed buggy boolean --enable-foo / --disable-foo configure script |
67 |
parameters |
68 |
- global.h now only covers global definitions that are needed for the |
69 |
C++ API header files, all implementation internal global definitions |
70 |
are now in global_private.h |
71 |
- atomic.h is not exposed to the C++ API anymore |
72 |
- no need to include config.h anymore for using LS's API header files |
73 |
- fixed warnings in API doc generation |
74 |
|
75 |
* general changes: |
76 |
- replaced the old, confusing MIDI program change mechanism by a |
77 |
flexible MIDI instrument mapper which allows to map arbitrary |
78 |
(MIDI bank, MIDI program) pairs with arbitrary |
79 |
(engine type, instrument file, file index) triplets which will be |
80 |
loaded on the respective channel when such MIDI program change |
81 |
messages arrive, beside that, each entry allows to define a life-time |
82 |
strategy for the instrument, so the user can define whether the |
83 |
instrument should i.e. be permanently loaded (to be able to switch |
84 |
quickly among sounds) or i.e. loaded just on demand when the |
85 |
respective program change arrives (to safe RAM space), as well as a |
86 |
global volume factor for each entry, so the user can adjust the volume |
87 |
dynamic of his mapped instrument collection without having to modify |
88 |
the instrument files, also one can manage arbitrary amount of such |
89 |
MIDI instrument maps and assign each sampler channel individually |
90 |
a certain map, so that i.e. separation of normal instruments and |
91 |
drumkits is possible |
92 |
- new notification events for tracking changes to audio/MIDI devices, |
93 |
MIDI instrument maps, MIDI instruments, FX sends, global volume. |
94 |
- sampler was limited to load max. 200 instruments in the background |
95 |
due to a constant size RingBuffer FIFO which is now replaced by a |
96 |
dynamic (unlimited) size std::list FIFO |
97 |
- added FX sends, these allow to route audio signals to arbitrary audio |
98 |
output channels for being processed by external effect processors |
99 |
(i.e. jack-rack), the send levels are controllable via arbitrary MIDI |
100 |
controllers |
101 |
- global (sampler wide) volume can now be controlled at runtime |
102 |
- Implemented new, improved notification system |
103 |
- fixed compilation errors regarding OSX |
104 |
(patch by Toshi Nagata) |
105 |
- implemented instruments database |
106 |
- added support for escape sequences to the instruments database |
107 |
- added highly experimental support for on-the-fly instrument editing |
108 |
within the sampler's process (by using instrument editor plugins), |
109 |
you'll notice the new "Registered instrument editors:" message on |
110 |
startup, added a new LSCP command: |
111 |
"EDIT CHANNEL INSTRUMENT <sampler-channel>" |
112 |
to spawn a matching instrument editor for the instrument on the |
113 |
given sampler channel, the plugin path can be overridden at compile |
114 |
time with ./configure --enable-plugin-dir=/some/dir |
115 |
- added experimental code for synchronizing instrument editors hosted |
116 |
in the sampler's process to safely edit instruments while playing |
117 |
without a crash (hopefully) by either suspending single regions |
118 |
wherever possible or if unavoidable whole engine(s) |
119 |
- fixed several issues in fundamental "Thread" class: set scheduling |
120 |
policy and priority on thread level, set a minimum stack size for |
121 |
thread (TODO: a reasonable value yet to be tested), bugfix: non-RT |
122 |
threads simply inherited properties of starting thread instead of |
123 |
setting their own policy and priority |
124 |
- minor fix in our automatic stack trace mechanism on crashes, the |
125 |
main process did not wait for the stack trace process to finish |
126 |
its output |
127 |
- fixed some minor memory leaks |
128 |
- reenabled assembly features support, at the moment only for |
129 |
enabling a fast denormal FPU mode (x86 platforms supporting SSE2) |
130 |
- minor assembly fix in x86 features detection (don't use the PIC |
131 |
register, to avoid relocations in the text segment at runtime) |
132 |
- POSIX callback functions of Thread.h are hidden |
133 |
|
134 |
* MIDI driver: |
135 |
- dispatch bank select (MSB and LSB) messages |
136 |
|
137 |
* audio driver: |
138 |
- the ALSA audio output driver parameters now reflect the correct |
139 |
parameter value ranges for the respective selected sound card |
140 |
(patch by Till Wimmer, a bit fixed and extended) |
141 |
|
142 |
* Gigasampler format engine: |
143 |
- if a filter is used and EG2 finishes before EG1, let the voice |
144 |
die when EG2 has finished (this fixes a problem with clicks and |
145 |
voice starvation for some gigs) |
146 |
- playback is no longer disabled during instrument loading |
147 |
- all notes playing on a channel that changes its instrument keep |
148 |
playing with the old instrument until they get a note off |
149 |
command |
150 |
- EG fix: a release value of zero could cause noises or crash |
151 |
- handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB) |
152 |
- EG fine tuning: when attack is zero the EG starts at a level |
153 |
above max sustain level, which means that there is a decay phase |
154 |
even if sustain is 100% |
155 |
- more EG fixes: the level could sometimes go below zero and cause |
156 |
noises or crashes |
157 |
- minor fix of EGDecay (patch by Toshi Nagata) |
158 |
- fixed compiler error when --enable-override-filter-type was |
159 |
supplied to the configure script (fixes #46) |
160 |
- disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS |
161 |
instead of a fix value |
162 |
- behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode), |
163 |
127 (solo mode) only kill voices if the respective mode really |
164 |
changed |
165 |
|
166 |
* LSCP server: |
167 |
- fixed compile time error for old Bison versions |
168 |
(i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata) |
169 |
- parser now supports extended ASCII character set |
170 |
(up to ASCII code 255, i.e. includes now umlauts and accents) |
171 |
- filename arguments in LSCP commands now allow to use escape |
172 |
sequences, that is directly literal as one of: \', \", \\, \n, \r, |
173 |
\f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII |
174 |
code value like \xf2) (fixes bug #24) |
175 |
- the following LSCP commands now also support escape sequences for at |
176 |
least one of their text-based parameters (i.e. name, description): |
177 |
"ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT", |
178 |
"SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND", |
179 |
"SET DB_INSTRUMENT_DIRECTORY NAME", |
180 |
"SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME", |
181 |
"SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS", |
182 |
"FIND DB_INSTRUMENT_DIRECTORIES" |
183 |
- returns verbose syntax errors (line and column where syntax error |
184 |
occured, the unexpected character and the actually expected, possible |
185 |
character(s), the latter only if less than 5 possibilities) |
186 |
- made sure that LSCP syntax is not affected by gigedit locale |
187 |
settings |
188 |
- bugfix regarding strings parameter lists: all comma separated lists |
189 |
of strings were treated as being one string containing commas |
190 |
(fixes #57) |
191 |
|
192 |
* Bug fixes: |
193 |
- fixed crash occurring on certain LSCP scripts (Bug 39) |
194 |
- another thread safety fix for lscp "load engine" and "set |
195 |
channel audio output device" |
196 |
- fixed a crash which occurs when reassigning the same engine |
197 |
on a sampler channel with connected MIDI device |
198 |
- fixed a crash which occurs when changing the number of ports of a MIDI |
199 |
device connected to a sampler channel to number less then or equal |
200 |
to the index of the port to which the sampler channel is connected. |
201 |
- The previous bindings were not been disconnected when altering |
202 |
the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for |
203 |
unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE). |
204 |
- The active stream/voice count statistic was incorrect. |
205 |
- notification events were not been sent for some sampler |
206 |
channel changes |
207 |
- added default min and max values to restrict the number of allowed |
208 |
audio output channels and MIDI input ports |
209 |
- the connection to the PCM interface is now closed when destroying |
210 |
an audio output device |
211 |
- files with slash in their path or filename could not be loaded |
212 |
|
213 |
* test cases: |
214 |
- updated and fixed (haven't been touched in a while) |
215 |
|
216 |
Version 0.4.0 (24 November 2006) |
217 |
|
218 |
* packaging changes: |
219 |
- changed deprecated copyright attribute to license; added ldconfig |
220 |
to post-(un)install steps; added devel package for liblinuxsampler; |
221 |
to linuxsampler.spec (RPM) |
222 |
- install necessary development header files for allowing 3rd party |
223 |
applications to link against liblinuxsampler |
224 |
- liblinuxsampler's API documentation can be generated with 'make docs' |
225 |
(Doxygen required) |
226 |
- added benchmark to automatically detect the best triangle LFO |
227 |
implementation (currently either an integer math solution or a |
228 |
di-harmonic approximation), automatic detection can be overriden |
229 |
with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x |
230 |
configure script argument though (mandatory for cross-compilation) |
231 |
- do not automatically pick optimized gcc flags if the user already |
232 |
provided some on his own (as CXXFLAGS) |
233 |
- added compile time option to disable processing of All-Notes-Off MIDI |
234 |
messages |
235 |
- added compile time options to allow disabling the various audio and |
236 |
MIDI drivers |
237 |
- fixed automatic GCC CPU switch detection on PPC |
238 |
(patch by Ebrahim Mayat) |
239 |
|
240 |
* Gigasampler format engine: |
241 |
- extensive synthesis optimization |
242 |
(reimplementation of EGs and LFO(s), removed synthesis parameter |
243 |
prerendering and the synthesis parameter matrix in general, splitting |
244 |
each audio fragment into subfragments now where each subfragment uses |
245 |
constant pitch and filter coefficients. The volume coefficient is |
246 |
linearly interpolated inside a subfragment, unless |
247 |
--disable-interpolate-volume is set.) |
248 |
- fine tuning of the EG modulation parameters |
249 |
- improved filter cutoff calculation by adding support for the |
250 |
following gig parameters: Cutoff freq (used when no cutoff |
251 |
controller is defined), Control invert, Minimum cutoff, Velocity |
252 |
curve and Velocity range. The keyboard tracking now scales |
253 |
cutoff frequency instead of resonance. |
254 |
- added support for gig parameter Resonance. |
255 |
- fixed bug in sysex handling (patch by Juan Linietsky) |
256 |
- added global volume attenuation of -9 dB (0.35f) to prevent clipping |
257 |
which can be overridden with --enable-global-attenuation |
258 |
- EG fixes: made the length of "attack hold" stage more |
259 |
accurate. Release stage can now start before attack stage |
260 |
ends. Cancel release didn't work when sustain was zero. Attack |
261 |
time now has a minimal value to prevent clicks. |
262 |
- fixed pitch changes larger than one octave |
263 |
- fixed EG3 (pitch envelope) synthesis which was neutral all the time |
264 |
- implemented portamento mode and solo mode (a.k.a 'mono mode'): |
265 |
all modes can be altered via standard GM messages, that is CC5 for |
266 |
altering portamento time, CC65 for enabling / disabling portamento |
267 |
mode, CC126 for enabling solo mode and CC127 for disabling solo mode |
268 |
- fine tuning of the curves for volume (CC7), pan (CC10 and gig |
269 |
parameter) and crossfade |
270 |
- added support for the "attenuation controller threshold" gig |
271 |
parameter |
272 |
- added smoothing of volume changes caused by control change |
273 |
messages |
274 |
- sample loop parameters are now taken from the DimensionRegion |
275 |
instead of the wave chunk |
276 |
- fixed keyswitching for v3 gigs with a number of keyswitch splits |
277 |
not equal to a power of two |
278 |
- reimplementation of the filter algorithm. The new filter is more |
279 |
accurate and supports all gig filter types, including bandreject |
280 |
and lowpass turbo. |
281 |
- real support for 24 bit samples - samples are not truncated to |
282 |
16 bits anymore |
283 |
- support for aftertouch (channel pressure, not polyphonic |
284 |
aftertouch) |
285 |
- LFO1 behaviour fixed (dampening from max volume instead of |
286 |
amplifying from 0) |
287 |
|
288 |
* LSCP server: |
289 |
- fixed application exit on broken pipe error (fixes bug #20) |
290 |
- fixed the notification messages delay due to lack of |
291 |
network activity (fixes bug #26) |
292 |
- fixed parser bug which occured on space(s) within device parameters |
293 |
(e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'") |
294 |
|
295 |
* audio driver: |
296 |
- added aRts audio output driver (by no means RT safe) |
297 |
|
298 |
* MIDI driver: |
299 |
- fixed legacy sysex code which caused dispatching of MIDI SysEx |
300 |
messages several times instead of once |
301 |
- API extension for MIDI drivers which already supply exact time stamps |
302 |
for events (i.e. for offline rendering based MIDI drivers) |
303 |
- added checks for bad MIDI data |
304 |
|
305 |
* linuxsampler application: |
306 |
- show available sampler engine types on startup |
307 |
|
308 |
* general changes: |
309 |
- support for muting sampler channels and solo mode of the same, two new |
310 |
LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new |
311 |
fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were |
312 |
introduced for this, the behavior is the same like on a mixer console |
313 |
(patch by Grigor Iliev, a bit adjusted). Also added configure option |
314 |
--enable-process-muted-channels which can be used to enable the |
315 |
processing of muted channels. |
316 |
- support for sostenuto pedal |
317 |
- support for monitoring the total number of active voices |
318 |
(new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX, |
319 |
SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT) |
320 |
- fixed some memory management errors |
321 |
- fixed some concurrency problems that could lead to crashes when |
322 |
LSCP commands were executed |
323 |
- fixed crash when instrument loading failed previously on the same |
324 |
sampler channel (fixes bug #36) |
325 |
|
326 |
Version 0.3.3 (15 July 2005) |
327 |
|
328 |
* packaging changes: |
329 |
- fixed compilation with gcc 4.0 |
330 |
|
331 |
* Gigasampler format engine: |
332 |
- LFO preprocessing was performed even though the respective LFO was |
333 |
disabled by the instrument patch (minor efficiency fix) |
334 |
- if period time of chosen audio device is too small (< MIN_RELEASE_TIME) |
335 |
for volume ramp downs in the same fragment (needed for current voice |
336 |
stealing implementation) then simply inform the user with a warning |
337 |
about possible click sounds and reduce the volume ramp down |
338 |
appropriately instead of cancelling the audio device connection |
339 |
|
340 |
Version 0.3.2 (24 June 2005) |
341 |
|
342 |
* packaging changes: |
343 |
- updated autotools build files to compile on OS X |
344 |
(conditional compilation of CoreMIDI and MidiShare drivers) |
345 |
- hand-crafted assembly optimization code can be disabled with |
346 |
'./configure --disable-asm' (definitely not recommended) |
347 |
- fixed 'make dist' rule to include all necessary files |
348 |
- require automake (>= 1.5) for 'make -f Makefile.cvs' |
349 |
(due to 'dist-bzip2' automake option) |
350 |
|
351 |
* Gigasampler format engine: |
352 |
- support for the gig parameters for "release velocity response" curves |
353 |
- fine tuning of the EGADSR envelope |
354 |
- volume of release triggered samples now depends on note-on velocity, |
355 |
note length and gig parameter "release trigger decay" instead of |
356 |
note-off velocity. |
357 |
- revised voice stealing |
358 |
(fixes crash and endless loop caused by voice stealing) |
359 |
- don't reset scale tuning on instrument or audio output device change |
360 |
- handle key group conflicts right at the beginning of each fragment |
361 |
instead of when the respective voice is actually launched |
362 |
(fixes undefined behavior if stolen voices belonged to a key group - |
363 |
this case was followed by a "killed voice survived" error message) |
364 |
- fixed minor issue with null/silence samples |
365 |
(those stole voices even though they don't need a voice at all which |
366 |
resulted in "voice stealing didn't work out" messages) |
367 |
- don't reset volume, pan, pitch and MIDI controller values on |
368 |
instrument or audio output device change |
369 |
|
370 |
* LSCP server: |
371 |
- fixed some crashes (patch by Grigor Iliev, fixes #19) |
372 |
- fixed LSCP event "CHANNEL_INFO" notification |
373 |
(e.g. did not notify on volume changes or MIDI program change events) |
374 |
|
375 |
* linuxsampler application: |
376 |
- added command line parameters --lscp-addr and --lscp-port to override |
377 |
default IP address and port of LSCP server |
378 |
|
379 |
Version 0.3.1 (24 May 2005) |
380 |
|
381 |
* initial release |
