Keyboard Instrument.

I was stuck by the idea that there are no perfect ratios when tuning a piano. For instance, if you play a song on a piano, it will sound better in the middle register. I wanted to be able to fine tune the keys on the fly. So I made this little ap in Max/MSP.

Since it is so old, it only runs on OS9. So if you download it, you need an older Mac to run it.
