My Prophet 5 Rev 4, 2022 model experiences the following problem: When I hit Tune then the instrument tunes all the oscillators perfectly, but not to 440Hz. The tuning randomly is off so far that I either have to turn the master tune knob all the way to the left and next tuning cycle all the eay to the right. Having the tuning knob in center position never gives me 440Hz tuning.
Does anyone experience this? And is there a fix?

Is one of the non-standard tuning tables selected in the globals menu perhaps? Set it back to equal temperament.
If that’s not it. You could try clearing the tuning calibration tables (record+tune) and repopulating them by hitting “tune” every time it needs it.

Also check that the latest firmware is installed. It is always posted in the first thread of this forum.
