i think the dsp thing would be too much, way over my head anyway. anyone with a bit of patience would get a microprocessor, of the basic stamp/atmel64 type, up and running and clocking away happily in a few hours.
dsp in assembler language is heavy stuff, and i think the number of those interested would be too small to make it commercially viable for doepfer, but perhaps this is just my own biased view.
i see two groups for whom the much simpler version would be interesting. obviously those who are up for programming, but also users interested in what other people make available. anyone out there looking for a clock divider that resets to all outputs high (the opposite of the a160), for example, wouldn't have to wait long, that'd be my first.
and then the charles babbage memorial analytical engine, maybe :)
