In keeping any particular interval type at a constant beat rate... you automatically curve all other types for that interval... and ditto for other intervals and their types. Keeping a constant beat rate for the 12th (and I use the perfect 12th for ease right now and because it actually works pretty good), causes the different octave types to develope along very predictable lines... or curves as it were. And whats neat about it is that they seem to rather make these exact transitions quite smoothly, and well within what we otherwise expect from these kinds of octave stretching schemes. >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.

I remember years ago fooling around with a strobe tuner, didnt know what I was doing really, but my first tendancy was to use it much like I use Tunelab now.. manually referencing already tuned notes to get frequencies for notes to tune. >Also, since we're complaining about the limitations of the 490ST, doesn't >the Yamaha PT-100 have the same limitations?

Dont know anything about the PT 100 myself. Would be interested to hear more tho.. Cheers RicB > >Charles Richard Brekne RPT NPTF Griegakadamiet UiB
