Bridge and wound string parameters

OldMike

I noticed that Pianoscope only asks for the breaks between bridges and wound-plain strings when starting a pitch raise, and not when doing a regular tuning. Am I missing something? The few other ETDs I’ve used all require this info before any tuning, because of the discontinuities in inharmonicity there. I was puzzled when I saw this… It does such a great job of accurately tuning; how does it tune without this information?

With pianoscope you sample all the notes so that the app can acoustically record the actual inharmonicities. By this it does not have to make any assumptions because it can make precise measurements.
During a pitch raise it has to predict the movement of the soundboard of which it needs the positions of the bridges and struts.
