I only have one Maths...maybe soon two. While I don't have the money to shell out for a whole rack of Maths, man would I want to play with such a thing. Could probably have 2-4 at audio rates (I suppose 2 if you don't have a mixer), and the rest LFOs and LFOs modulating other LFOs. I dunno...give me the rack and I'll give you some patches
