x0xb0x is tuned down 10 half-notes

Post by roxxx303 »

Hi

my x0xb0x is not in tune anymore all of a sudden (The "TUNE"-knob is centered!).
C is 10 half-note-steps deeper than C. :(
With the "TUNE"-knob I can turn it 8 half-note-steps higher, but it's still 2 half-notes deeper than C!

What has happened and what can I do?

Thanks!

ignoring that it's off, check if the C on the next octave is twice the frequency or not
and check if the 5.333V line hasn't drifted away

The upper C is exactly tuned one octave up!
I cannot measure voltage, I am a total noob!

But I think there must be a trimmer to adjust the master pitch of the x0x,
so that the centered "tune"-knob creates a C again when pressing a C-note-button!

Please help! :cry:
