reference tone A=0 instead of C=0 possible?

[fbs789]

Hello, I’m looking for a way to create a custom tuning with A=0.

Unfortunately, I can’t find a way to set a note other than C=0/1200 as the reference point.
(Historical tunings are usually specified relative to either A or C. I prefer A - and if I just want to raise or lower the C for testing purposes, I’d have to change all 11 other values...)

If this really isn’t currently possible, I’d be delighted if a corresponding modification could be made!

Best regards,
Bernie

Hi, not sure if I underestand correctly, but if I do, it is as simple as changing the key note. So, you define you tuning in C, but when finally selecting it to use it, choose the key note to A. See the attached video.

Alternatively, you can of your course change all 11 notes, right. But when done, you can copy it when changing the tuning.

Or you can import a text file and prepare tunings somewhere else. Just export a tuning to see how it looks ...
