being another old 8bit computer junkie, i can only agree with the other reviews :-)
one thing id like to add is that even if you take the "c 64-soundalike" concept out of the consideration, this thing really really sounds good. the oscillators have a very fat, almost rude and aggressive quality to them. cuts through in the mix like hell. so, whether you want a c 64 SID clone or just a good sounding synth with character, this is a true winner.
i even think the user interface is OK, but the one thing id really like to see would be virtual knobs in addition to the parameter readouts. shift dragging numbers is even less intuitive than turning virtual knobs with a mouse, so theres room for improvement here :-)
but other than that, this synth is perfect :-)
