A map from [0-1] to an arbitrary range, specified using low/mid/high values. Pulled out from some Signalsmith Audio internal code.

vMin = min;
double k = (mid - min)/(max - mid);
vTopFactor = max*k - min;
vBottomFactor = k - 1;

A FAUST-based drum and percussion synth with three components: band-limited noise through a feedback delay, noise and FM
// NOTE: as-is, this does NOT work correctly with faust2lv2, since it does not support MIDI input via the "key" parameter.
// It does work with the FAUST web IDE and Faust Live, though.
