I saw that this morning. A very interesting design, love the apparent simplicity of Ray's designs
The audio samples sound tasty! Ray always has some kick ass stuff. I'm intrigued. Trying to find a suitable DIP8 rail to rail opamp which is common and accessible.

Ray was suggesting the TL972. It's $1, but I can only find it at Mouser. I'm going to try the TLC2272.
Cool. Ray does use quite a lot of rail to rail opamps. I have some tlc2272 kicking around I'll give it a go.
