Hi Ben,
I saw your keyboard on 8 bit keys and got inspired, I have big love of synthesised audio, and would like to get a copy of your keyboard schematics, so I can have a go at building the keyboard, but seeing as I have a little more time on my hands, I will be going a few extra steps.
But if I could get a copy of your schematics and notes that would be great. It will also allow me to use my 3d printer for a bit of creativity
Many Thanks
Paul
