SID clocking - 1 cycle

v2 | voice 2 in |
v3 | voice 3 in |
Implements reSIDfp::Filter.
void reSIDfp::Filter6581::setFilterCurve | ( | double | curvePosition | ) |
Set filter curve type based on single parameter.
curvePosition | 0 .. 1, where 0 sets center frequency high ("light") and 1 sets it low ("dark") |
|
virtual |
Switch to new distortion curve.
Implements reSIDfp::Filter.

Mixing configuration modified (offsets change)
Implements reSIDfp::Filter.

Resonance tuned by ear, based on a few observations:
Implements reSIDfp::Filter.
