Tony Rolando really knocked it out of the park with the Maths design, actually. The Maths is ridiculously capable as a modulation source or, since it descends from the Serge DUSG, you could even use it as an oscillator. It turns up all over the place, almost like a standard device, because it's VERY difficult to overtax it in terms of complexity...despite it being deceptively simple to use. 20 hp of lightning in a bottle!
