Same basic concept as the VC Clock Divider patch but with an audio rate signal.
Square wave --> Maths Ch. 1 & Ch. 4 Trig in
Ch. 1 EOR out --> VCA 1 signal in
Ch. 2 EOC out --> VCA 2 signal in
VCA 1 & 2 out --> monitors
Adjusting the Rise time (either manually or with voltage) changes the division amount
