Discussion about the Korg PolySix synthesizer

I don't mean to insult you, but if you're new to scopes then you
might not be aware that many have adjustable attenuation controls on X/Y
inputs, via either or both an analogue control or a multi-position
switch. It would be worth checking the scope's user manual for more
information if you haven't already done so. Then again, maybe it is just
poorly calibrated :) 

Cheers,
A.

gave me nothing at all.... no offset ... and pin 40 gave me a healthy dc
only offset.

and 2 on my scope dont agree at all and also dont agree with my dmm when
