It's true, the lack of PWM on the Model D could be a deal-breaker. But if you've got other synthesizers that have PWM, it's not such a problem. Plus, the minor improvements made to this rendition of the Minimoog - especially the second LFO - made it even better than the original, which is saying a lot. It was a very attractive instrument.
These disappointments repeatedly make me wish DSI would solve the problem once and for all by creating an all-new VCO mono synth (And don't tell me it's unrealistic for this reason and that reason; I'm dreaming, okay?). No, not a Toraiz with a keyboard, nor a Prophet 6 in mono mode, but a new design, unrelated to the other DSI pieces, but still with classic DSI architecture and warm chunky voltage controlled oscillators.
THE big mono synth of mono synths to clean the clocks of all others.
Otherwise, I vote for the Rev2 as the mono synth of the year.
