All that you say is true, but there's also sense in finishing the job, in making an instrument that provides what are, for many of us, only standard practical necessities. After all, the OB-6 is not a complex creature. It offers just the basics. So, finish with the basics. Dave did it with the Prophet 12. Why not do it again with an instrument that is so very different in sonic character?
Anyways, I hope DSI produces some full-sized analog instrument in the next year or so. Maybe the replacement for the Prophet '08?
