The Vermona Perfourmer Mk II has impressed me for a couple of years, but I've never played one. There are precious few YouTube videos of it, and they're of rather poor audio quality. Nor have I found even one in which the instrument is extensively played from a keyboard.
A simple question: Does the instrument have a high-quality analog tone? Used in unison, can it produce a sawtooth lead type patch that could stand up to a Moog? Rich, warm, fat, and all that stuff?
