Nice! Is the uScale mainly for the TM? Might be better to get a Disting then. Disting has a TM-algorithm with built in quantization and can do like 70 other things too.

I'm not sure what the Maths is for since you don't have much CV to mix in this rack? Envelopes and LFOs? If that's the case then there are other, less hp-consuming options.
