I have wanted to learn how to "see" sound since I was a teenager listening to Isao Tomita, Patrick Moraz, Larry Fast, Pascal, Jeane Michael Moore, Morton Subotnick, Keith Emerson, Rick Wakeman, & countless others who mystified & inspired me. No matter how hard I worked I could never make the kind of money required to even touch a MOOG, Sequential Circuts, Waldorf, Hammond, Rhoads, or anything even approaching their likes. Now finally in my sunset of time on Earth ignoring arthritis & other annoying & irratating distractions I am learning to SYNTHESIZE! (I can hear Todd Rungren in the background). I am beyond excited . . . I am sublime . . . Walter/Wendy can you hear me? Some dreams are ETERNAL! This unit is incredible! But it is more tool than toy to learn how to synthesize NOT to reinforce your music - What it offers is not the technogically advanced soundscape available today but rather like having an instructor teach you the language & operations involved in learning to fly. Although this magnificent machine will get you airborne it is a Cessna single prop NOT an F-16. For myself this is PRICELESS, just floating above the clouds taking my time. If you are not a pianist & want to immediately jump into a jet for musical background reinforcement then my suggestion is the Novation line. I am a guitarist but deeply cherish the craftwork of GODS like Isao Tomita so I bought the Novation Bass Station a decade ago & love it but it is very forgiving to someone like myself. Now I am learning properly "How to SEE sound" & I must thank KORG from the depths of my soul for this magnificent learning tool -
