Rick When you measure the current pitches when preparing a pitch-raise, you have to make a compromise between the time it takes to measure the notes and the precision of the pitch measurement: The more notes you record the better pianoscope can predict the plate movement. In principle you can measure any amount or pattern of notes you want. Traditionally, I suggested to play the notes of the A minor triad. But for unevenly out-of-tune pianos, it can make sense to measure more notes, like with minor thirds or major seconds. When the piano is more than 50 cents flat, pianoscope cannot perform automatic note detection. To save you work from having to manually select every note you want to record on the on-screen keyboard, I now provide these default patterns with which pianoscope prompts you to play notes.
If you before used to start a pitch-raise via the inharmonicity measurement of the full scale, not much changes. It is mainly meant for having a good way to start a coarse tuning in the pitch-raise function with a choice of multiple note patterns. Does this make sense?
