3    * packaging changes:    * 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) and pan (CC10 and gig
48          parameter)
49        - added support for the "attenuation controller threshold" gig
50          parameter
51    
52      * LSCP server:
53        - fixed application exit on broken pipe error (fixes bug #20)
54        - fixed the notification messages delay due to lack of
55          network activity (fixes bug #26)
56        - fixed parser bug which occured on space(s) within device parameters
57          (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
58    
59      * MIDI driver:
60        - fixed legacy sysex code which caused dispatching of MIDI SysEx
61          messages several times instead of once
62    
63      * general changes:
64        - support for muting sampler channels and solo mode of the same, two new
65          LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
66          fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
67          introduced for this, the behavior is the same like on a mixer console
68          (patch by Grigor Iliev, a bit adjusted). Also added configure option
69          --enable-process-muted-channels which can be used to enable the
70          processing of muted channels.
71        - support for sostenuto pedal
72        - support for monitoring the total number of active voices
73          (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
74          SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
75    
76    Version 0.3.3 (15 July 2005)
77    
78      * packaging changes:
79      - fixed compilation with gcc 4.0      - fixed compilation with gcc 4.0
