Indeed it is a great module and came with my Doepfer A100 Basic System 1 to get me started on modular. That and Quadrax are solid contenders to Maths. Since I already have a Make Noise 0-coast that has Slope/Contour which is like a mini-Maths, I wanted some variety. Befaco Rampage and Frap Tools Falistri also look like interesting variations on the Serge/Buchla complex function generator as well. Eurorack has infinite choices compared to the limits of other systems. But it all points back to the big three of modular: Moog, Serge, and Buchla. If I was filthy rich, I would just get a Moog System 15, Buchla Skylab or the classic modules, and Serge setups. But I'd need 50-100k for Serge/Buchla/Moog systems compared to 20k of Eurorack.
