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    
14      * Gigasampler format engine:
15        - extensive synthesis optimization
16          (reimplementation of EGs and LFO(s), removed synthesis parameter
17          prerendering and the synthesis parameter matrix in general, splitting
18          each audio fragment into subfragments now where each subfragment uses
19          constant synthesis parameters - that is volume, pitch and filter
20          coefficients)
21        - fine tuning of the EG modulation parameters
22        - improved filter cutoff calculation by adding support for the
23          following gig parameters: Cutoff freq (used when no cutoff
24          controller is defined), Control invert, Minimum cutoff, Velocity
25          curve and Velocity range. The keyboard tracking now also scales
26          cutoff frequency, not just resonance.
27        - fixed bug in sysex handling (patch by Juan Linietsky)
28    
29      * LSCP server:
30        - fixed application exit on broken pipe error (fixes bug #20)
31    
32      * MIDI driver:
33        - fixed legacy sysex code which caused dispatching of MIDI SysEx
34          messages several times instead of once
35    
36      * general changes:
37        - support for muting sampler channels and solo mode of the same, two new
38          LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
39          fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
40          introduced for this, the behavior is the same like on a mixer console
41          (patch by Grigor Iliev, a bit adjusted). Also added configure option
42          --enable-process-muted-channels which can be used to enable the
43          processing of muted channels.
44        - support for sostenuto pedal
45    
46    Version 0.3.3 (15 July 2005)
47    
48      * packaging changes:
49      - fixed compilation with gcc 4.0      - fixed compilation with gcc 4.0
50    
51      * Gigasampler format engine:
52        - LFO preprocessing was performed even though the respective LFO was
53          disabled by the instrument patch (minor efficiency fix)
54        - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
55          for volume ramp downs in the same fragment (needed for current voice
56          stealing implementation) then simply inform the user with a warning
57          about possible click sounds and reduce the volume ramp down
58          appropriately instead of cancelling the audio device connection
59
