Uh, while I think it&#x27;s perfectly reasonable to like using a Gameboy for music tinkering, that whole &quot;immediacy&quot; thing you cite about composition process is essentially what got solved with Propellerhead&#x27;s Figure. I&#x27;ve had it since the first version and it&#x27;s grown into my personal, portable drum&#x2F;bass&#x2F;synth sketchpad and recommend it to anybody serious about composing on the go. Just because you don&#x27;t know what&#x27;s out there doesn&#x27;t mean it&#x27;s not out there, for what it&#x27;s worth.
