I like the way in which PianoScope seems to be taking shape as a teaching tool. I appreciate Ed Sutton‘s comments on this in the Piano World forums. I am repeating here something I said that lies buried in a thread he started a few days ago.
“You've got me going Ed! Now I want a new feature in the program -- a pitch raise mode where the tone generator produces not the final pitch for the tuning, but rather the pitch raise target, together with a persistent on-screen mute button to use for tuning unisons-as-you-go.
Also, for major pitch raises, I would value the ability to set a preliminary tuning curve with a smaller number of samples, such that I could bring half a dozen or so strings up to pitch on an instrument that needs a particularly large pitch raise, and create a tuning curve based on them. I do understand that increasing the loading of the soundboard also contributes to inharmonicity change, but this still might take me closer to where I need to be when I proceed to taking a full inharmonicity measurement in preparation for fine tuning.“
I am working with any eager aspiring tuner, and would like to do what I can to minimize early reliance on a visual source. He is most likely to be starting out with pianos that need pitch adjustments before any meaningful work on temperament setting can take place. The tone generating feature of this program could be a game changer in this situation.
