(Per-voice DACs, that is.) Nope. In the DOC-based synths there was a single DAC for all control voltages and the DOC built-in DAC for all audio channels. Anything with a DOC chip (Mirage, ESQ and SQ range, and their sampled electric piano) had real CEM analogue filters. > > It depends on the software involved.

It's only because I spend *hours* listening to single notes from digital oscillators sweeping up and down trying to catch little bits of aliasing that I notice, to be entirely honest.
