First CV Audio From 2A03

I needed a break from working on the new Pokey.synth code, so I took this afternoon to get the DE0-Nano input board (mentioned in the previous post) working with an audio channel on the NES. Today’s wave: the triangle.

This is a Make Noise Maths plus a little knob twiddling feeding the triangle wave pitch of the 2A03. It’s not following the volt per octave standard yet, but it’s smooth and responsive like a modular synth oscillator should be.
