727 PolyDistort + EQ
Eight stage distortion followed by equalization
PAUs: 2
PolyDistort + EQ is a distortion algorithm followed by equalization. The algorithm consists of an input
gain stage, and then eight cascaded distortion stages. Each stage is followed by a one pole LP Þlter. There
is also a one pole LP in front of the Þrst stage. After the distortion there is a 4 band EQ section: Bass, Treble,
and two Parametric Mids.
