(10 One potentiometer for internal clock signal (possibly external). Commonly called a "Baby 8", so called because it's a simple implementation. Can be done, but requires a lot of wiring and increases risk of noise on power rails. Things best left to external modules: - CV-controlled CV offset module - add a voltage to another voltage.
