Hey there! This is just a code test, really, and a filler project. I was playing around with the Noteblocks, and realised that there is no damper pedal, or any effect like that - or at least not one I know of. (For those of you that don't know, on pianos there are damper pedals that makes the previous note you played last longer, and it sort of links the notes together.) So after experimenting a bit, I figured it out - it's not really complicated at all.
