Saving Pitch Raise Data

Tom Dowell

Is there any way to save the pitch raise data of how much each string deviates from the tuning curve? It seems it would be helpful for diagnosing humidity/structural issues, of the same areas are going flat/sharp, and being able to show that to the customer.

I looked through the help files and didn’t find any reference. Even just being able to export as a csv file might be helpful on often tuned pianos or pianos in extreme environments. Thank you!

There is currently no way of exporting the pitch raise data from pianoscope to csv.

But if you just want to show the measurements to the customer, you can simply re-open the pitch raise measurements panel at any time. It shows the cents offsets from your last pitch raise.

If you really want to get your hands on the raw data, you can open the pianoscope document in a text editor and take a look at the "overpull" section. It contains the first partial frequencies from the pitch raise measurements. To get the cents offset from the tuning curve you would need to implement some calculation in Excel to compare it to the target frequencies in the "tuning" section. The data in the tuning document is in JSON format. Excel is able to directly import JSON data, but I have no experience with this feature.

I see. Thank you!

I take screenshots and save them to an album. It would be great if Pianoscope had a function that allows the image to be assigned to the tune file and the instrument. Name-date.image in the directory of the tune file.
