Most people I've heard that tried the DeepMind say that it's an OK synth, but that there is nothing about it that triggers them to really want one... I've not tried one myself, but it's just what I hear people who tried it say... if there is a bit of the "Behringer Placebo Effect" involved I cannot say.... but still... the pricepoint is it's strongest point still, plus the built in FX section.
For me there is no use for the Behringer... neither any of the analog DSI synths... my Prophet 12's oscillators and the semi-modular approach is much more versatile than say, a REV2... the only thing it offers is the analog oscillators, and FX section in my opinion. Sure it has a different sound, but I can do with the P12.
My next synth will be the Novation PEAK, simply because it offers something unique, and with flexible oscillators... I'll probably not buy another DSI product until they come out with a sampling synthesizer hybrid (if).
