* packaging changes: |
4 |
schoenebeck |
1212 |
- config.h is not going to be installed along with liblinuxsampler's |
5 |
|
|
API header files anymore |
6 |
schoenebeck |
1065 |
- only the API relevant header (and source) files will be exported to |
7 |
|
|
the Doxygen API documentation (explicitly listed in Doxyfile.in) |
8 |
schoenebeck |
1175 |
- added completely new XCode project files for Mac OSX which is now |
9 |
|
|
capable to execute our autoconf environment, thus no need anymore |
10 |
|
|
to maintain the compile time configuration file (osx/version.h) for |
11 |
|
|
OSX manually (patch by Toshi Nagata) |
12 |
schoenebeck |

* general changes: |
14 |
|
|
- replaced the old, confusing MIDI program change mechanism by a |
15 |
|
|
flexible MIDI instrument mapper which allows to map arbitrary |
16 |
schoenebeck |
973 |
(MIDI bank, MIDI program) pairs with arbitrary |
17 |
schoenebeck |
947 |
(engine type, instrument file, file index) triplets which will be |
18 |
|
|
loaded on the respective channel when such MIDI program change |
19 |
|
|
messages arrive, beside that, each entry allows to define a life-time |
20 |
|
|
strategy for the instrument, so the user can define whether the |
21 |
|
|
instrument should i.e. be permanently loaded (to be able to switch |
22 |
|
|
quickly among sounds) or i.e. loaded just on demand when the |
23 |
|
|
respective program change arrives (to safe RAM space), as well as a |
24 |
|
|
global volume factor for each entry, so the user can adjust the volume |
25 |
|
|
dynamic of his mapped instrument collection without having to modify |
26 |
schoenebeck |
973 |
the instrument files, also one can manage arbitrary amount of such |
27 |
|
|
MIDI instrument maps and assign each sampler channel individually |
28 |
|
|
a certain map, so that i.e. separation of normal instruments and |
29 |
|
|
drumkits is possible |
30 |
iliev |
1108 |
- new notification events for tracking changes to audio/MIDI devices, |
31 |
|
|
MIDI instrument maps, MIDI instruments, FX sends, global volume. |
32 |
schoenebeck |
990 |
- sampler was limited to load max. 200 instruments in the background |
33 |
|
|
due to a constant size RingBuffer FIFO which is now replaced by a |
34 |
|
|
dynamic (unlimited) size std::list FIFO |
35 |
schoenebeck |
1001 |
- added FX sends, these allow to route audio signals to arbitrary audio |
36 |
|
|
output channels for being processed by external effect processors |
37 |
|
|
(i.e. jack-rack), the send levels are controllable via arbitrary MIDI |
38 |
|
|
controllers |
39 |
schoenebeck |
1005 |
- global (sampler wide) volume can now be controlled at runtime |
40 |
iliev |
1130 |
- Implemented new, improved notification system |
41 |
schoenebeck |
1149 |
- fixed compilation errors regarding OSX |
42 |
|
|
(patch by Toshi Nagata) |
43 |
iliev |
1161 |
- implemented instruments database |
44 |
schoenebeck |
1212 |
- added highly experimental support for on-the-fly instrument editing |
45 |
|
|
within the sampler's process (by using instrument editor plugins), |
46 |
|
|
you'll notice the new "Registered instrument editors:" message on |
47 |
|
|
startup, added a new LSCP command "EDIT INSTRUMENT <sampler-channel>" |
48 |
|
|
to spawn a matching instrument editor for the instrument on the |
49 |
|
|
given sampler channel, the plugin path can be overridden at compile |
50 |
|
|
time with ./configure --enable-plugin-dir=/some/dir |
51 |
schoenebeck |
1221 |
- fixed several issues in fundamental "Thread" class: set scheduling |
52 |
|
|
policy and priority on thread level, set a minimum stack size for |
53 |
|
|
thread (TODO: a reasonable value yet to be tested), bugfix: non-RT |
54 |
|
|
threads simply inherited properties of starting thread instead of |
55 |
|
|
setting their own policy and priority |
56 |
schoenebeck |
1233 |
- minor fix in our automatic stack trace mechanism on crashes, the |
57 |
|
|
main process did not wait for the stack trace process to finish |
58 |
|
|
its output |
59 |
persson |
1248 |
- fixed some minor memory leaks |
60 |
schoenebeck |
947 |
|
61 |
|
|
* MIDI driver: |
62 |
|
|
- dispatch bank select (MSB and LSB) messages |
63 |
|
|
|
64 |
schoenebeck |
1049 |
* audio driver: |
65 |
|
|
- the ALSA audio output driver parameters now reflect the correct |
66 |
|
|
parameter value ranges for the respective selected sound card |
67 |
|
|
(patch by Till Wimmer, a bit fixed and extended) |
68 |
|
|
|
69 |
persson |
951 |
* Gigasampler format engine: |
70 |
|
|
- if a filter is used and EG2 finishes before EG1, let the voice |
71 |
|
|
die when EG2 has finished (this fixes a problem with clicks and |
72 |
|
|
voice starvation for some gigs) |
73 |
persson |
1038 |
- playback is no longer disabled during instrument loading |
74 |
|
|
- all notes playing on a channel that changes its instrument keep |
75 |
|
|
playing with the old instrument until they get a note off |
76 |
|
|
command |
77 |
persson |
1039 |
- EG fix: a release value of zero could cause noises or crash |
78 |
schoenebeck |
1041 |
- handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB) |
79 |
persson |
1046 |
- EG fine tuning: when attack is zero the EG starts at a level |
80 |
|
|
above max sustain level, which means that there is a decay phase |
81 |
|
|
even if sustain is 100% |
82 |
persson |
1147 |
- more EG fixes: the level could sometimes go below zero and cause |
83 |
|
|
noises or crashes |
84 |
schoenebeck |
1149 |
- minor fix of EGDecay (patch by Toshi Nagata) |
85 |
schoenebeck |
1181 |
- fixed compiler error when --enable-override-filter-type was |
86 |
|
|
supplied to the configure script (fixes #46) |
87 |
persson |
951 |
|
88 |
schoenebeck |
1244 |
* LSCP server: |
89 |
|
|
- fixed compile time error for old Bison versions |
90 |
|
|
(i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata) |
91 |
schoenebeck |
1245 |
- parser now supports extended ASCII character set |
92 |
|
|
(up to ASCII code 255, i.e. includes now umlauts and accents) |
93 |
|
|
- filename arguments in LSCP commands now allow to use escape |
94 |
|
|
sequences, that is directly literal as one of: \', \", \\, \n, \r, |
95 |
|
|
\f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII |
96 |
|
|
code value like \xf2) (fixes bug #24) |
97 |
schoenebeck |
1244 |

98 |
iliev |
959 |
* Bug fixes: |
99 |
|
|
- fixed crash occurring on certain LSCP scripts (Bug 39) |
100 |
persson |
1038 |
- another thread safety fix for lscp "load engine" and "set |
101 |
|
|
channel audio output device" |
102 |
iliev |
959 |
|
103 |
schoenebeck |

697 |
* packaging changes: |
109 |
capela |
868 |
- changed deprecated copyright attribute to license; added ldconfig |
110 |
|
|
to post-(un)install steps; added devel package for liblinuxsampler; |
111 |
|
|
to linuxsampler.spec (RPM) |
112 |
schoenebeck |
697 |
- install necessary development header files for allowing 3rd party |
113 |
|
|
applications to link against liblinuxsampler |
114 |
|
|
- liblinuxsampler's API documentation can be generated with 'make docs' |
115 |
|
|
(Doxygen required) |
116 |
schoenebeck |
715 |
- added benchmark to automatically detect the best triangle LFO |
117 |
|
|
implementation (currently either an integer math solution or a |
118 |
|
|
di-harmonic approximation), automatic detection can be overriden |
119 |
|
|
with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x |
120 |
|
|
configure script argument though (mandatory for cross-compilation) |
121 |
schoenebeck |
829 |
- do not automatically pick optimized gcc flags if the user already |
122 |
|
|
provided some on his own (as CXXFLAGS) |
123 |
schoenebeck |
849 |
- added compile time option to disable processing of All-Notes-Off MIDI |
124 |
|
|
messages |
125 |
schoenebeck |
852 |
- added compile time options to allow disabling the various audio and |
126 |
|
|
MIDI drivers |
127 |
schoenebeck |
909 |
- fixed automatic GCC CPU switch detection on PPC |
128 |

persson |
696 |
* Gigasampler format engine: |
131 |
schoenebeck |
738 |
- extensive synthesis optimization |
132 |
|
|
(reimplementation of EGs and LFO(s), removed synthesis parameter |
133 |
|
|
prerendering and the synthesis parameter matrix in general, splitting |
134 |
|
|
each audio fragment into subfragments now where each subfragment uses |
135 |
persson |
830 |
constant pitch and filter coefficients. The volume coefficient is |
136 |
|
|
linearly interpolated inside a subfragment, unless |
137 |
|
|
--disable-interpolate-volume is set.) |
138 |
persson |
696 |
- fine tuning of the EG modulation parameters |
139 |
persson |
729 |
- improved filter cutoff calculation by adding support for the |
140 |
|
|
following gig parameters: Cutoff freq (used when no cutoff |
141 |
|
|
controller is defined), Control invert, Minimum cutoff, Velocity |
142 |
persson |
791 |
curve and Velocity range. The keyboard tracking now scales |
143 |
|
|
cutoff frequency instead of resonance. |
144 |
persson |
877 |
- added support for gig parameter Resonance. |
145 |
schoenebeck |
775 |
- fixed bug in sysex handling (patch by Juan Linietsky) |
146 |
schoenebeck |
781 |
- added global volume attenuation of -9 dB (0.35f) to prevent clipping |
147 |
|
|
which can be overridden with --enable-global-attenuation |
148 |
persson |
783 |
- EG fixes: made the length of "attack hold" stage more |
149 |
|
|
accurate. Release stage can now start before attack stage |
150 |
persson |
797 |
ends. Cancel release didn't work when sustain was zero. Attack |
151 |
|
|
time now has a minimal value to prevent clicks. |
152 |
persson |
799 |
- fixed pitch changes larger than one octave |
153 |
schoenebeck |
829 |
- fixed EG3 (pitch envelope) synthesis which was neutral all the time |
154 |
|
|
- implemented portamento mode and solo mode (a.k.a 'mono mode'): |
155 |
|
|
all modes can be altered via standard GM messages, that is CC5 for |
156 |
|
|
altering portamento time, CC65 for enabling / disabling portamento |
157 |
|
|
mode, CC126 for enabling solo mode and CC127 for disabling solo mode |
158 |
persson |
832 |
- fine tuning of the curves for volume (CC7), pan (CC10 and gig |
159 |
|
|
parameter) and crossfade |
160 |
persson |
831 |
- added support for the "attenuation controller threshold" gig |
161 |
|
|
parameter |
162 |
persson |
832 |
- added smoothing of volume changes caused by control change |
163 |
|
|
messages |
164 |
persson |
865 |
- sample loop parameters are now taken from the DimensionRegion |
165 |
|
|
instead of the wave chunk |
166 |
|
|
- fixed keyswitching for v3 gigs with a number of keyswitch splits |
167 |
|
|
not equal to a power of two |
168 |
persson |
877 |
- reimplementation of the filter algorithm. The new filter is more |
169 |
|
|
accurate and supports all gig filter types, including bandreject |
170 |
|
|
and lowpass turbo. |
171 |
persson |
903 |
- real support for 24 bit samples - samples are not truncated to |
172 |
|
|
16 bits anymore |
173 |
|
|
- support for aftertouch (channel pressure, not polyphonic |
174 |
|
|
aftertouch) |
175 |
persson |
922 |
- LFO1 behaviour fixed (dampening from max volume instead of |
176 |
|
|
amplifying from 0) |
177 |
persson |
696 |
|
178 |
schoenebeck |
711 |
* LSCP server: |
179 |
|
|
- fixed application exit on broken pipe error (fixes bug #20) |
180 |
iliev |
793 |
- fixed the notification messages delay due to lack of |
181 |
|
|
network activity (fixes bug #26) |
182 |
schoenebeck |
826 |
- fixed parser bug which occured on space(s) within device parameters |
183 |
|
|
(e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'") |
184 |
schoenebeck |
711 |
|
185 |
schoenebeck |
838 |
* audio driver: |
186 |
|
|
- added aRts audio output driver (by no means RT safe) |
187 |
|
|
|
188 |
schoenebeck |
775 |
* MIDI driver: |
189 |
|
|
- fixed legacy sysex code which caused dispatching of MIDI SysEx |
190 |
|
|
messages several times instead of once |
191 |
schoenebeck |
906 |
- API extension for MIDI drivers which already supply exact time stamps |
192 |
|
|
for events (i.e. for offline rendering based MIDI drivers) |
193 |
persson |
922 |
- added checks for bad MIDI data |
194 |
schoenebeck |
775 |
|
195 |
schoenebeck |
900 |
* linuxsampler application: |
196 |
|
|
- show available sampler engine types on startup |
197 |
|
|
|
198 |
schoenebeck |
705 |
* general changes: |
199 |
|
|
- support for muting sampler channels and solo mode of the same, two new |
200 |
|
|
LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new |
201 |
|
|
fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were |
202 |
|
|
introduced for this, the behavior is the same like on a mixer console |
203 |
iliev |
716 |
(patch by Grigor Iliev, a bit adjusted). Also added configure option |
204 |
|
|
--enable-process-muted-channels which can be used to enable the |
205 |
|
|
processing of muted channels. |
206 |
iliev |
777 |
- support for sostenuto pedal |
207 |
iliev |
779 |
- support for monitoring the total number of active voices |
208 |
iliev |
778 |
(new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX, |
209 |
|
|
SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT) |
210 |
persson |
835 |
- fixed some memory management errors |
211 |
persson |
841 |
- fixed some concurrency problems that could lead to crashes when |
212 |
|
|
LSCP commands were executed |
213 |
schoenebeck |
925 |
- fixed crash when instrument loading failed previously on the same |
214 |
|
|
sampler channel (fixes bug #36) |

Version 0.3.3 (15 July 2005) |
217 |
schoenebeck |
686 |
|
218 |
|
|
* packaging changes: |
219 |
|
|
- fixed compilation with gcc 4.0 |
220 |
|
|
|
221 |
schoenebeck |
687 |
* Gigasampler format engine: |
222 |
|
|
- LFO preprocessing was performed even though the respective LFO was |
223 |
|
|
disabled by the instrument patch (minor efficiency fix) |
224 |
schoenebeck |
688 |
- if period time of chosen audio device is too small (< MIN_RELEASE_TIME) |
225 |
|
|
for volume ramp downs in the same fragment (needed for current voice |
226 |
|
|
stealing implementation) then simply inform the user with a warning |
227 |
|
|
about possible click sounds and reduce the volume ramp down |
228 |
|
|
appropriately instead of cancelling the audio device connection |

Version 0.3.2 (24 June 2005) |
231 |
schoenebeck |
609 |
|
232 |
|
|
* packaging changes: |
233 |
|
|
- updated autotools build files to compile on OS X |
234 |
|
|
(conditional compilation of CoreMIDI and MidiShare drivers) |
235 |
schoenebeck |
617 |
- hand-crafted assembly optimization code can be disabled with |
236 |
|
|
'./configure --disable-asm' (definitely not recommended) |
237 |
schoenebeck |
654 |
- fixed 'make dist' rule to include all necessary files |
238 |
|
|
- require automake (>= 1.5) for 'make -f Makefile.cvs' |
239 |
|
|
(due to 'dist-bzip2' automake option) |
240 |
schoenebeck |
649 |
|
241 |
|
|
* Gigasampler format engine: |
242 |
|
|
- support for the gig parameters for "release velocity response" curves |
243 |
|
|
- fine tuning of the EGADSR envelope |
244 |
|
|
- volume of release triggered samples now depends on note-on velocity, |
245 |
|
|
note length and gig parameter "release trigger decay" instead of |
246 |
|
|
note-off velocity. |
247 |
schoenebeck |
663 |
- revised voice stealing |
248 |
|
|
(fixes crash and endless loop caused by voice stealing) |
249 |
schoenebeck |
659 |
- don't reset scale tuning on instrument or audio output device change |
250 |
schoenebeck |
668 |
- handle key group conflicts right at the beginning of each fragment |
251 |
|
|
instead of when the respective voice is actually launched |
252 |
|
|
(fixes undefined behavior if stolen voices belonged to a key group - |
253 |
|
|
this case was followed by a "killed voice survived" error message) |
254 |
schoenebeck |
669 |
- fixed minor issue with null/silence samples |
255 |
|
|
(those stole voices even though they don't need a voice at all which |
256 |
|
|
resulted in "voice stealing didn't work out" messages) |
257 |
schoenebeck |
670 |
- don't reset volume, pan, pitch and MIDI controller values on |
258 |
|
|
instrument or audio output device change |

262 |
schoenebeck |
660 |
- fixed LSCP event "CHANNEL_INFO" notification |
263 |
schoenebeck |

(e.g. did not notify on volume changes or MIDI program change events) |
264 |
schoenebeck |
609 |
|
265 |
schoenebeck |
668 |
* linuxsampler application: |
266 |
