Grandmother Tuning Trimpots?

[naturecol]

hey there,

manual does not show so I need to ask here: are there tuning trimpots inside the grandmother? - I need to adjust the pitch-in tracking of the oscillators, as they don't scale like my other analog synths (including moog ones). now what I am looking for is (hidden) trimpots like the mother32 has. also, the KB-Out is offset by a lot (650 cents abouts), seems to be tracking my other synths nice though, so I would need an offset trimpot for that.

please let me know

Did you ever figure this out?
My GM is drastically out of tune, even after running the calibration tool.
I know of the three trimpots in the back but I've never adjusted something like that before, not sure what tool to buy and how to safely adjust it.
