This is actually very impressive! so what made you want to start this project, anyhow? it seems like a rather large undertaking. I can see this being immensely helpful for anyone starting out, or artists that don't want to get too involved in electronics. Overall it seems like a very solid project, but needs a few tweaks and improvements/expansions (no plain resistors on the parts list?). If you can keep developing it, I'd be very excited to see where it can go.
