Version CVS HEAD (?) |
2 |
|
3 |
* packaging changes: |
4 |
- install necessary development header files for allowing 3rd party |
5 |
applications to link against liblinuxsampler |
6 |
- liblinuxsampler's API documentation can be generated with 'make docs' |
7 |
(Doxygen required) |
8 |
- added benchmark to automatically detect the best triangle LFO |
9 |
implementation (currently either an integer math solution or a |
10 |
di-harmonic approximation), automatic detection can be overriden |
11 |
with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x |
12 |
configure script argument though (mandatory for cross-compilation) |
13 |
- do not automatically pick optimized gcc flags if the user already |
14 |
provided some on his own (as CXXFLAGS) |
15 |
|
16 |
* Gigasampler format engine: |
17 |
- extensive synthesis optimization |
18 |
(reimplementation of EGs and LFO(s), removed synthesis parameter |
19 |
prerendering and the synthesis parameter matrix in general, splitting |
20 |
each audio fragment into subfragments now where each subfragment uses |
21 |
constant pitch and filter coefficients. The volume coefficient is |
22 |
linearly interpolated inside a subfragment, unless |
23 |
--disable-interpolate-volume is set.) |
24 |
- fine tuning of the EG modulation parameters |
25 |
- improved filter cutoff calculation by adding support for the |
26 |
following gig parameters: Cutoff freq (used when no cutoff |
27 |
controller is defined), Control invert, Minimum cutoff, Velocity |
28 |
curve and Velocity range. The keyboard tracking now scales |
29 |
cutoff frequency instead of resonance. |
30 |
- filter fine tuning: calculation of cutoff frequency and |
31 |
bandwidth improved. Removed use of "BasicBPFilter". Changed |
32 |
bandpass filter from constant peak to constant skirt. Added |
33 |
support for gig parameter Resonance. |
34 |
- fixed bug in sysex handling (patch by Juan Linietsky) |
35 |
- added global volume attenuation of -9 dB (0.35f) to prevent clipping |
36 |
which can be overridden with --enable-global-attenuation |
37 |
- EG fixes: made the length of "attack hold" stage more |
38 |
accurate. Release stage can now start before attack stage |
39 |
ends. Cancel release didn't work when sustain was zero. Attack |
40 |
time now has a minimal value to prevent clicks. |
41 |
- fixed pitch changes larger than one octave |
42 |
- fixed EG3 (pitch envelope) synthesis which was neutral all the time |
43 |
- implemented portamento mode and solo mode (a.k.a 'mono mode'): |
44 |
all modes can be altered via standard GM messages, that is CC5 for |
45 |
altering portamento time, CC65 for enabling / disabling portamento |
46 |
mode, CC126 for enabling solo mode and CC127 for disabling solo mode |
47 |
- fine tuning of the curves for volume (CC7), pan (CC10 and gig |
48 |
parameter) and crossfade |
49 |
- added support for the "attenuation controller threshold" gig |
50 |
parameter |
51 |
- added smoothing of volume changes caused by control change |
52 |
messages |
53 |
|
54 |
* LSCP server: |
55 |
- fixed application exit on broken pipe error (fixes bug #20) |
56 |
- fixed the notification messages delay due to lack of |
57 |
network activity (fixes bug #26) |
58 |
- fixed parser bug which occured on space(s) within device parameters |
59 |
(e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'") |
60 |
|
61 |
* audio driver: |
62 |
- added aRts audio output driver (by no means RT safe) |
63 |
|
64 |
* MIDI driver: |
65 |
- fixed legacy sysex code which caused dispatching of MIDI SysEx |
66 |
messages several times instead of once |
67 |
|
68 |
* general changes: |
69 |
- support for muting sampler channels and solo mode of the same, two new |
70 |
LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new |
71 |
fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were |
72 |
introduced for this, the behavior is the same like on a mixer console |
73 |
(patch by Grigor Iliev, a bit adjusted). Also added configure option |
74 |
--enable-process-muted-channels which can be used to enable the |
75 |
processing of muted channels. |
76 |
- support for sostenuto pedal |
77 |
- support for monitoring the total number of active voices |
78 |
(new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX, |
79 |
SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT) |
80 |
- fixed some memory management errors |
81 |
|
82 |
Version 0.3.3 (15 July 2005) |
83 |
|
84 |
* packaging changes: |
85 |
- fixed compilation with gcc 4.0 |
86 |
|
87 |
* Gigasampler format engine: |
88 |
- LFO preprocessing was performed even though the respective LFO was |
89 |
disabled by the instrument patch (minor efficiency fix) |
90 |
- if period time of chosen audio device is too small (< MIN_RELEASE_TIME) |
91 |
for volume ramp downs in the same fragment (needed for current voice |
92 |
stealing implementation) then simply inform the user with a warning |
93 |
about possible click sounds and reduce the volume ramp down |
94 |
appropriately instead of cancelling the audio device connection |
95 |
|
96 |
Version 0.3.2 (24 June 2005) |
97 |
|
98 |
* packaging changes: |
99 |
- updated autotools build files to compile on OS X |
100 |
(conditional compilation of CoreMIDI and MidiShare drivers) |
101 |
- hand-crafted assembly optimization code can be disabled with |
102 |
'./configure --disable-asm' (definitely not recommended) |
103 |
- fixed 'make dist' rule to include all necessary files |
104 |
- require automake (>= 1.5) for 'make -f Makefile.cvs' |
105 |
(due to 'dist-bzip2' automake option) |
106 |
|
107 |
* Gigasampler format engine: |
108 |
- support for the gig parameters for "release velocity response" curves |
109 |
- fine tuning of the EGADSR envelope |
110 |
- volume of release triggered samples now depends on note-on velocity, |
111 |
note length and gig parameter "release trigger decay" instead of |
112 |
note-off velocity. |
113 |
- revised voice stealing |
114 |
(fixes crash and endless loop caused by voice stealing) |
115 |
- don't reset scale tuning on instrument or audio output device change |
116 |
- handle key group conflicts right at the beginning of each fragment |
117 |
instead of when the respective voice is actually launched |
118 |
(fixes undefined behavior if stolen voices belonged to a key group - |
119 |
this case was followed by a "killed voice survived" error message) |
120 |
- fixed minor issue with null/silence samples |
121 |
(those stole voices even though they don't need a voice at all which |
122 |
resulted in "voice stealing didn't work out" messages) |
123 |
- don't reset volume, pan, pitch and MIDI controller values on |
124 |
instrument or audio output device change |
125 |
|
126 |
* LSCP server: |
127 |
- fixed some crashes (patch by Grigor Iliev, fixes #19) |
128 |
- fixed LSCP event "CHANNEL_INFO" notification |
129 |
(e.g. did not notify on volume changes or MIDI program change events) |
130 |
|
131 |
* linuxsampler application: |
132 |
- added command line parameters --lscp-addr and --lscp-port to override |
133 |
default IP address and port of LSCP server |
134 |
|
135 |
Version 0.3.1 (24 May 2005) |
136 |
|
137 |
* initial release |
