interesting stuff. I went experimenting some more, and made frames that contained 2 sines, and then put in 2, 3, 4, 5, and 6 square waves.
creates cool sounds where you have more freedom in playing different notes together, not just octaves etc.
I found one a few years ago for 10 euro's. And I'm in the process of modding it extensively. Trigger input. Programmable rhythms. Tone twisters. It's such an awesome machine to work with :)
