[sdiy] Electric Druid NoteDiv Chips

[Elaine Klopke]

I'll try doing the ANDing with a logic gate when I get home and see if I get the same result. My ears could just be weird.

They're set up to run on their internal clocks because I am fond of imperfection and colour and freerunning notes is a thing I enjoy. But seriously peeps, if you're even thinking about starting a top octave style synth/organ/thingy project get these. They're worth every penny.
