Tuning calibration?

[Æsc]

My OSC 1 TUNE (master tune) knob is about 40 cents flat at noon. There is no good visual indicator for when the knob is in tune (A440)—this being slightly to the right of noon. How can the master tune be re-calibrated? I’ve gone through multiple power cycles and also have had the power on for hours at a time, and the synth has been in a stable climate for 5 days.

To run this Tuning Procedure, you must upgrade to firmware v1.0.7

SETTINGS -> CONFIG(PGM 16) -> PAGE TO 4(64) -> PGM 14
Wait for tuning to complete. Approx. 14 seconds.

Hi EnjoyRC! Thanks for this. I did not see this procedure in the manual. FWIW, I did it twice and it does not fix the issue. My guess is this tunes the oscillators to themselves. Noon on OSC 1 TUNE (global tune) is still around 40 cents flat.

Anyone else experiencing this issue?

N.B. I have discovered that the OSC 1 TUNE param saves with the patch. So if I am editing with the “default” position of noon on the knob, the patch will save and recall ~40 cents flat. (Now I check with the tuner before saving. Or I retune and resave previously saved patches.) This might seem like a HUGE drag if I have to go through this every time I design a patch, but mercifully the INIT patch loads at A440. So as long as I don’t ever touch that OSC 1 TUNE knob…

same here, and it's not limited to the tune knob on my unit - which is why i started a thread of my own before finding yours.

on mine, it's actually worse on the osc2 freq and osc mod amount knobs.

this clearly seems to be a knob calibration issue, so the tuning procedure won't help here.

i've created a support ticket with inmusic about this and would encourage anybody experiencing similar issues to do the same.

hopefully, they will add a panel calibration procedure to the messenger (if it isn't already there, just undocumented) like the ones available for sub37 or muse...
