The tutorial about and demonstration of the “Zeroscillator” (Voltage Modular) is online:
It´s epic! It´s 2 hours full of information and tips. It´s everything one can know about the Zeroscillator. It´s all you need to know about exponential FM, classic linear FM and through-zero FM, and makes you really understand these things.
It´s complete indeed.
