Version CVS HEAD (?) |
2 |
|
3 |
* general changes: |
4 |
- bugfix: on some POSIX systems instrument editor plugins refused to |
5 |
load as we used a non-portable Linux specific struct field |
6 |
(fixes bug #70, patch by Ronald Baljeu) |
7 |
|
8 |
* audio driver: |
9 |
- removed the nonsense audio channel constraint (which was hard coded to |
10 |
max. 100 audio channels) for most audio drivers |
11 |
|
12 |
Version 0.5.1 (6 December 2007) |
13 |
|
14 |
* packaging changes: |
15 |
- added autoconf checks for pthread library |
16 |
- added autoconf check for pthread bug found on certain NPTL-enabled |
17 |
glibc versions (see Gentoo bug report #194076) |
18 |
- added autoconf checks for MS Windows |
19 |
|
20 |
* general changes: |
21 |
- bugfix: the thread used by an editor plugin didn't die when the |
22 |
editor closed |
23 |
- bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero |
24 |
out all the space. operator--() did not apply size_mask after |
25 |
decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in |
26 |
order to avoid problems with the _NonVolatileReader functions. |
27 |
- bugfix: Stream.h: added a missing divide by BytesPerSample in |
28 |
GetWriteSpace(). Since this function is currently only used in |
29 |
the stream's qsort() compare function, it didn't trigger any |
30 |
bugs. |
31 |
- Resampler.h, Synthesizer.h: cubic interpolation now works in |
32 |
24bit mode too. Faster method to read 24bit words on little |
33 |
endian machines (x86): replaced 3 byte reads + shifts with a 1 |
34 |
unaligned 32bit read and shift |
35 |
- experimental support for MS Windows (MIDI input via MME, AUDIO |
36 |
output via ASIO) |
37 |
- made handling of SIGINT signal (Ctrl-C) a bit more robust |
38 |
- support for monitoring the total number of active disk streams |
39 |
(new LSCP commands: GET TOTAL_STREAM_COUNT, |
40 |
SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT) |
41 |
|
42 |
* AUDIO driver: |
43 |
- added Windows ASIO low latency audio driver |
44 |
|
45 |
* MIDI driver: |
46 |
- added MME Windows MIDI driver |
47 |
|
48 |
* LSCP server: |
49 |
- added support for Windows style path / filenames, however with |
50 |
forward slash path separators instead of backslash |
51 |
(i.e. "C:/foo/bar.gig") |
52 |
- allow naughty liblscp to send non-string device parameters within |
53 |
apostrophes as well |
54 |
- added new LSCP commands: "GET FILE INSTRUMENTS <file>", |
55 |
"LIST FILE INSTRUMENTS <file>" and |
56 |
"GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations |
57 |
about an arbitrary instrument file on the system where the sampler is |
58 |
running on |
59 |
|
60 |
Version 0.5.0 (15 October 2007) |
61 |
|
62 |
* packaging changes: |
63 |
- config.h is not going to be installed along with liblinuxsampler's |
64 |
API header files anymore |
65 |
- only the API relevant header (and source) files will be exported to |
66 |
the Doxygen API documentation (explicitly listed in Doxyfile.in) |
67 |
- added completely new XCode project files for Mac OSX which is now |
68 |
capable to execute our autoconf environment, thus no need anymore |
69 |
to maintain the compile time configuration file (osx/version.h) for |
70 |
OSX manually (patch by Toshi Nagata) |
71 |
- fixed buggy boolean --enable-foo / --disable-foo configure script |
72 |
parameters |
73 |
- global.h now only covers global definitions that are needed for the |
74 |
C++ API header files, all implementation internal global definitions |
75 |
are now in global_private.h |
76 |
- atomic.h is not exposed to the C++ API anymore |
77 |
- no need to include config.h anymore for using LS's API header files |
78 |
- fixed warnings in API doc generation |
79 |
|
80 |
* general changes: |
81 |
- replaced the old, confusing MIDI program change mechanism by a |
82 |
flexible MIDI instrument mapper which allows to map arbitrary |
83 |
(MIDI bank, MIDI program) pairs with arbitrary |
84 |
(engine type, instrument file, file index) triplets which will be |
85 |
loaded on the respective channel when such MIDI program change |
86 |
messages arrive, beside that, each entry allows to define a life-time |
87 |
strategy for the instrument, so the user can define whether the |
88 |
instrument should i.e. be permanently loaded (to be able to switch |
89 |
quickly among sounds) or i.e. loaded just on demand when the |
90 |
respective program change arrives (to safe RAM space), as well as a |
91 |
global volume factor for each entry, so the user can adjust the volume |
92 |
dynamic of his mapped instrument collection without having to modify |
93 |
the instrument files, also one can manage arbitrary amount of such |
94 |
MIDI instrument maps and assign each sampler channel individually |
95 |
a certain map, so that i.e. separation of normal instruments and |
96 |
drumkits is possible |
97 |
- new notification events for tracking changes to audio/MIDI devices, |
98 |
MIDI instrument maps, MIDI instruments, FX sends, global volume. |
99 |
- sampler was limited to load max. 200 instruments in the background |
100 |
due to a constant size RingBuffer FIFO which is now replaced by a |
101 |
dynamic (unlimited) size std::list FIFO |
102 |
- added FX sends, these allow to route audio signals to arbitrary audio |
103 |
output channels for being processed by external effect processors |
104 |
(i.e. jack-rack), the send levels are controllable via arbitrary MIDI |
105 |
controllers |
106 |
- global (sampler wide) volume can now be controlled at runtime |
107 |
- Implemented new, improved notification system |
108 |
- fixed compilation errors regarding OSX |
109 |
(patch by Toshi Nagata) |
110 |
- implemented instruments database |
111 |
- added support for escape sequences to the instruments database |
112 |
- added highly experimental support for on-the-fly instrument editing |
113 |
within the sampler's process (by using instrument editor plugins), |
114 |
you'll notice the new "Registered instrument editors:" message on |
115 |
startup, added a new LSCP command: |
116 |
"EDIT CHANNEL INSTRUMENT <sampler-channel>" |
117 |
to spawn a matching instrument editor for the instrument on the |
118 |
given sampler channel, the plugin path can be overridden at compile |
119 |
time with ./configure --enable-plugin-dir=/some/dir |
120 |
- added experimental code for synchronizing instrument editors hosted |
121 |
in the sampler's process to safely edit instruments while playing |
122 |
without a crash (hopefully) by either suspending single regions |
123 |
wherever possible or if unavoidable whole engine(s) |
124 |
- fixed several issues in fundamental "Thread" class: set scheduling |
125 |
policy and priority on thread level, set a minimum stack size for |
126 |
thread (TODO: a reasonable value yet to be tested), bugfix: non-RT |
127 |
threads simply inherited properties of starting thread instead of |
128 |
setting their own policy and priority |
129 |
- minor fix in our automatic stack trace mechanism on crashes, the |
130 |
main process did not wait for the stack trace process to finish |
131 |
its output |
132 |
- fixed some minor memory leaks |
133 |
- reenabled assembly features support, at the moment only for |
134 |
enabling a fast denormal FPU mode (x86 platforms supporting SSE2) |
135 |
- minor assembly fix in x86 features detection (don't use the PIC |
136 |
register, to avoid relocations in the text segment at runtime) |
137 |
- POSIX callback functions of Thread.h are hidden |
138 |
|
139 |
* MIDI driver: |
140 |
- dispatch bank select (MSB and LSB) messages |
141 |
|
142 |
* audio driver: |
143 |
- the ALSA audio output driver parameters now reflect the correct |
144 |
parameter value ranges for the respective selected sound card |
145 |
(patch by Till Wimmer, a bit fixed and extended) |
146 |
|
147 |
* Gigasampler format engine: |
148 |
- if a filter is used and EG2 finishes before EG1, let the voice |
149 |
die when EG2 has finished (this fixes a problem with clicks and |
150 |
voice starvation for some gigs) |
151 |
- playback is no longer disabled during instrument loading |
152 |
- all notes playing on a channel that changes its instrument keep |
153 |
playing with the old instrument until they get a note off |
154 |
command |
155 |
- EG fix: a release value of zero could cause noises or crash |
156 |
- handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB) |
157 |
- EG fine tuning: when attack is zero the EG starts at a level |
158 |
above max sustain level, which means that there is a decay phase |
159 |
even if sustain is 100% |
160 |
- more EG fixes: the level could sometimes go below zero and cause |
161 |
noises or crashes |
162 |
- minor fix of EGDecay (patch by Toshi Nagata) |
163 |
- fixed compiler error when --enable-override-filter-type was |
164 |
supplied to the configure script (fixes #46) |
165 |
- disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS |
166 |
instead of a fix value |
167 |
- behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode), |
168 |
127 (solo mode) only kill voices if the respective mode really |
169 |
changed |
170 |
|
171 |
* LSCP server: |
172 |
- fixed compile time error for old Bison versions |
173 |
(i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata) |
174 |
- parser now supports extended ASCII character set |
175 |
(up to ASCII code 255, i.e. includes now umlauts and accents) |
176 |
- filename arguments in LSCP commands now allow to use escape |
177 |
sequences, that is directly literal as one of: \', \", \\, \n, \r, |
178 |
\f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII |
179 |
code value like \xf2) (fixes bug #24) |
180 |
- the following LSCP commands now also support escape sequences for at |
181 |
least one of their text-based parameters (i.e. name, description): |
182 |
"ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT", |
183 |
"SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND", |
184 |
"SET DB_INSTRUMENT_DIRECTORY NAME", |
185 |
"SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME", |
186 |
"SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS", |
187 |
"FIND DB_INSTRUMENT_DIRECTORIES" |
188 |
- returns verbose syntax errors (line and column where syntax error |
189 |
occured, the unexpected character and the actually expected, possible |
190 |
character(s), the latter only if less than 5 possibilities) |
191 |
- made sure that LSCP syntax is not affected by gigedit locale |
192 |
settings |
193 |
- bugfix regarding strings parameter lists: all comma separated lists |
194 |
of strings were treated as being one string containing commas |
195 |
(fixes #57) |
196 |
|
197 |
* Bug fixes: |
198 |
- fixed crash occurring on certain LSCP scripts (Bug 39) |
199 |
- another thread safety fix for lscp "load engine" and "set |
200 |
channel audio output device" |
201 |
- fixed a crash which occurs when reassigning the same engine |
202 |
on a sampler channel with connected MIDI device |
203 |
- fixed a crash which occurs when changing the number of ports of a MIDI |
204 |
device connected to a sampler channel to number less then or equal |
205 |
to the index of the port to which the sampler channel is connected. |
206 |
- The previous bindings were not been disconnected when altering |
207 |
the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for |
208 |
unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE). |
209 |
- The active stream/voice count statistic was incorrect. |
210 |
- notification events were not been sent for some sampler |
211 |
channel changes |
212 |
- added default min and max values to restrict the number of allowed |
213 |
audio output channels and MIDI input ports |
214 |
- the connection to the PCM interface is now closed when destroying |
215 |
an audio output device |
216 |
- files with slash in their path or filename could not be loaded |
217 |
|
218 |
* test cases: |
219 |
- updated and fixed (haven't been touched in a while) |
220 |
|
221 |
Version 0.4.0 (24 November 2006) |
222 |
|
223 |
* packaging changes: |
224 |
- changed deprecated copyright attribute to license; added ldconfig |
225 |
to post-(un)install steps; added devel package for liblinuxsampler; |
226 |
to linuxsampler.spec (RPM) |
227 |
- install necessary development header files for allowing 3rd party |
228 |
applications to link against liblinuxsampler |
229 |
- liblinuxsampler's API documentation can be generated with 'make docs' |
230 |
(Doxygen required) |
231 |
- added benchmark to automatically detect the best triangle LFO |
232 |
implementation (currently either an integer math solution or a |
233 |
di-harmonic approximation), automatic detection can be overriden |
234 |
with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x |
235 |
configure script argument though (mandatory for cross-compilation) |
236 |
- do not automatically pick optimized gcc flags if the user already |
237 |
provided some on his own (as CXXFLAGS) |
238 |
- added compile time option to disable processing of All-Notes-Off MIDI |
239 |
messages |
240 |
- added compile time options to allow disabling the various audio and |
241 |
MIDI drivers |
242 |
- fixed automatic GCC CPU switch detection on PPC |
243 |
(patch by Ebrahim Mayat) |
244 |
|
245 |
* Gigasampler format engine: |
246 |
- extensive synthesis optimization |
247 |
(reimplementation of EGs and LFO(s), removed synthesis parameter |
248 |
prerendering and the synthesis parameter matrix in general, splitting |
249 |
each audio fragment into subfragments now where each subfragment uses |
250 |
constant pitch and filter coefficients. The volume coefficient is |
251 |
linearly interpolated inside a subfragment, unless |
252 |
--disable-interpolate-volume is set.) |
253 |
- fine tuning of the EG modulation parameters |
254 |
- improved filter cutoff calculation by adding support for the |
255 |
following gig parameters: Cutoff freq (used when no cutoff |
256 |
controller is defined), Control invert, Minimum cutoff, Velocity |
257 |
curve and Velocity range. The keyboard tracking now scales |
258 |
cutoff frequency instead of resonance. |
259 |
- added support for gig parameter Resonance. |
260 |
- fixed bug in sysex handling (patch by Juan Linietsky) |
261 |
- added global volume attenuation of -9 dB (0.35f) to prevent clipping |
262 |
which can be overridden with --enable-global-attenuation |
263 |
- EG fixes: made the length of "attack hold" stage more |
264 |
accurate. Release stage can now start before attack stage |
265 |
ends. Cancel release didn't work when sustain was zero. Attack |
266 |
time now has a minimal value to prevent clicks. |
267 |
- fixed pitch changes larger than one octave |
268 |
- fixed EG3 (pitch envelope) synthesis which was neutral all the time |
269 |
- implemented portamento mode and solo mode (a.k.a 'mono mode'): |
270 |
all modes can be altered via standard GM messages, that is CC5 for |
271 |
altering portamento time, CC65 for enabling / disabling portamento |
272 |
mode, CC126 for enabling solo mode and CC127 for disabling solo mode |
273 |
- fine tuning of the curves for volume (CC7), pan (CC10 and gig |
274 |
parameter) and crossfade |
275 |
- added support for the "attenuation controller threshold" gig |
276 |
parameter |
277 |
- added smoothing of volume changes caused by control change |
278 |
messages |
279 |
- sample loop parameters are now taken from the DimensionRegion |
280 |
instead of the wave chunk |
281 |
- fixed keyswitching for v3 gigs with a number of keyswitch splits |
282 |
not equal to a power of two |
283 |
- reimplementation of the filter algorithm. The new filter is more |
284 |
accurate and supports all gig filter types, including bandreject |
285 |
and lowpass turbo. |
286 |
- real support for 24 bit samples - samples are not truncated to |
287 |
16 bits anymore |
288 |
- support for aftertouch (channel pressure, not polyphonic |
289 |
aftertouch) |
290 |
- LFO1 behaviour fixed (dampening from max volume instead of |
291 |
amplifying from 0) |
292 |
|
293 |
* LSCP server: |
294 |
- fixed application exit on broken pipe error (fixes bug #20) |
295 |
- fixed the notification messages delay due to lack of |
296 |
network activity (fixes bug #26) |
297 |
- fixed parser bug which occured on space(s) within device parameters |
298 |
(e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'") |
299 |
|
300 |
* audio driver: |
301 |
- added aRts audio output driver (by no means RT safe) |
302 |
|
303 |
* MIDI driver: |
304 |
- fixed legacy sysex code which caused dispatching of MIDI SysEx |
305 |
messages several times instead of once |
306 |
- API extension for MIDI drivers which already supply exact time stamps |
307 |
for events (i.e. for offline rendering based MIDI drivers) |
308 |
- added checks for bad MIDI data |
309 |
|
310 |
* linuxsampler application: |
311 |
- show available sampler engine types on startup |
312 |
|
313 |
* general changes: |
314 |
- support for muting sampler channels and solo mode of the same, two new |
315 |
LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new |
316 |
fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were |
317 |
introduced for this, the behavior is the same like on a mixer console |
318 |
(patch by Grigor Iliev, a bit adjusted). Also added configure option |
319 |
--enable-process-muted-channels which can be used to enable the |
320 |
processing of muted channels. |
321 |
- support for sostenuto pedal |
322 |
- support for monitoring the total number of active voices |
323 |
(new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX, |
324 |
SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT) |
325 |
- fixed some memory management errors |
326 |
- fixed some concurrency problems that could lead to crashes when |
327 |
LSCP commands were executed |
328 |
- fixed crash when instrument loading failed previously on the same |
329 |
sampler channel (fixes bug #36) |
330 |
|
331 |
Version 0.3.3 (15 July 2005) |
332 |
|
333 |
* packaging changes: |
334 |
- fixed compilation with gcc 4.0 |
335 |
|
336 |
* Gigasampler format engine: |
337 |
- LFO preprocessing was performed even though the respective LFO was |
338 |
disabled by the instrument patch (minor efficiency fix) |
339 |
- if period time of chosen audio device is too small (< MIN_RELEASE_TIME) |
340 |
for volume ramp downs in the same fragment (needed for current voice |
341 |
stealing implementation) then simply inform the user with a warning |
342 |
about possible click sounds and reduce the volume ramp down |
343 |
appropriately instead of cancelling the audio device connection |
344 |
|
345 |
Version 0.3.2 (24 June 2005) |
346 |
|
347 |
* packaging changes: |
348 |
- updated autotools build files to compile on OS X |
349 |
(conditional compilation of CoreMIDI and MidiShare drivers) |
350 |
- hand-crafted assembly optimization code can be disabled with |
351 |
'./configure --disable-asm' (definitely not recommended) |
352 |
- fixed 'make dist' rule to include all necessary files |
353 |
- require automake (>= 1.5) for 'make -f Makefile.cvs' |
354 |
(due to 'dist-bzip2' automake option) |
355 |
|
356 |
* Gigasampler format engine: |
357 |
- support for the gig parameters for "release velocity response" curves |
358 |
- fine tuning of the EGADSR envelope |
359 |
- volume of release triggered samples now depends on note-on velocity, |
360 |
note length and gig parameter "release trigger decay" instead of |
361 |
note-off velocity. |
362 |
- revised voice stealing |
363 |
(fixes crash and endless loop caused by voice stealing) |
364 |
- don't reset scale tuning on instrument or audio output device change |
365 |
- handle key group conflicts right at the beginning of each fragment |
366 |
instead of when the respective voice is actually launched |
367 |
(fixes undefined behavior if stolen voices belonged to a key group - |
368 |
this case was followed by a "killed voice survived" error message) |
369 |
- fixed minor issue with null/silence samples |
370 |
(those stole voices even though they don't need a voice at all which |
371 |
resulted in "voice stealing didn't work out" messages) |
372 |
- don't reset volume, pan, pitch and MIDI controller values on |
373 |
instrument or audio output device change |
374 |
|
375 |
* LSCP server: |
376 |
- fixed some crashes (patch by Grigor Iliev, fixes #19) |
377 |
- fixed LSCP event "CHANNEL_INFO" notification |
378 |
(e.g. did not notify on volume changes or MIDI program change events) |
379 |
|
380 |
* linuxsampler application: |
381 |
- added command line parameters --lscp-addr and --lscp-port to override |
382 |
default IP address and port of LSCP server |
383 |
|
384 |
Version 0.3.1 (24 May 2005) |
385 |
|
386 |
* initial release |
