This kit was built a few years back and was the 2nd project I’ve built from scratch. It’s a basic oscillator circuit with eight notes that are individually tunable. It is monophonic but pressing down multiple buttons will effect the pitch of the others because the resistance gets summed. I decided to used large arcade style buttons so you could rapidly tap on them for a percussive effect but it turns out to really shine as a bass square wave synth.

This was is an easy project and great for a beginning project. It was really more about learning about building and finishing the case and making sure it was usable and very “playable”.

Assembly complete, time to close it up and hear what it can do.
