This little devil is really cool. Virtually no learning curve. The concept of Simple Concept is quite brilliant IMHO. The TWEAK dice work just right... that is, they don't take you miles away from the current pre, yet serve up a totally relevant alternative. The algorithm seems to understand what I want. The factory presets are just right. Be careful though... you might spend a good deal of time having a blast with this synth before you realize how long you've been at it. A truly fascinating little hybrid virtual synth!!!!.
