I have to agree about the Peak. Seems like a nice synth but the demos always sounded a bit flat and boring to me. The OB-6, on the other hand, stood out as something special in demos and it puts a smile on my face every time I play it.
Digitone is the same. I knew I wanted that sound from the first demo I heard and it does not disappoint in person.
My point is, trust your gut when you have a strong response to a sound. There’s a better chance you’ll end up with an instrument you love when it “talks to you” through the sounds it makes than when you get caught up in features and theoretical capabilities.
