Hi Frank,

Many thanks for such a great tool. I watched your introduction video, and it is incredible what you have managed to achieve & learn in such a short space of time.

I was hoping I could be so humble as to request a further feature of PianoScope?

My use-case is this: I am not a piano-tuner, but I am someone who tunes his own piano, though with very little time to dedicate due to a busy work/family life. I try to catch 10-15 minutes here and there to tweak individual notes, but I very rarely have time to cover the whole keyboard range. Reading through this forum, I have seen others also describe the same experience & limitations I have.

What would really serve me well is to be able to quickly take a snapshot of the current tuning state (already possible via New Pitch Raise > Pre-Measure), and then be presented with a list of the notes sorted by absolute cent error. No fancy graphics or display needed, just a list. I could then re-tune the piano piecemeal with the time I have available.

I have seen it described here & elsewhere that a piano cannot be tuned in this way, but I would suggest otherwise, as I have been using the PianoScope tuning data files to achieve just this for the past few months.

Below is a screenshot of a program I have written that uses the tuning file to report back the cent error in a way that helps me target the most divergent notes.

(the listview shows each note and cent errors, sorted by absolute cent error. The graph shows absolute cent error and 1-cent marker/target line. The keyboard shows keys coloured green-yellow-red based on the magnitude of the cent error)

(note that I have my piano in Young 1799 temperament if the frequencies look a bit 'off')

It's clear from this display which notes need to be corrected, and I'm finding more frequently that most notes are within 1 cent error when I come to re-measure (depending on how hard the kids have been bashing the keys that week).

The downside to my own program is that I need to power up the laptop & copy tuning files across, which just adds to the time. It would be very handy to have a quick list to hand in the PianoScope app that lists the worst-to-best notes, along with cent error.

Many thanks again,
Andy
