Hi there, I'm getting major tuning issues with my KIWI-3P. The synth was calibrated towards the end of last year so am wondering if it's something to do with how the midi is functioning.

JX-3P DCO's are well known to be very stable which is why is so confusing. 

For example if I hold C it plays an F. I've tased without the PE attached and have done a factory reset and it's still out of tune.

If anyone has experience with this issue, any help would be greatly appreciated!

Thanks

J
