That's pretty much what I was thinking of as a rough start. One tricky thing is when you want to switch from 6:3 octaves to something else, at some point in the piano. You'd have to do it smoothly somehow. And I'm curious how to reconcile the info from more than one test note if there are conflicts. By the way, back to the discussion of the Peterson, you CAN tune a custom stretch with a Peterson 490ST based on the inharmonicity in a particular piano. You just have to do it manually. Every octave or so you can calculate how much that octave should be stretched, and then spread that stretch evenly throughout all 12 notes. Also, since we're complaining about the limitations of the 490ST, doesn't the Yamaha PT-100 have the same limitations? It's my understanding that it has presets for various Yamaha pianos. Since Yamaha is known to be fairly consistent in their manufacturing, it's probably a good ETD for tuning Yamaha pianos. Charles
