The scaling on my week-old m15 seems to be messed up.  I tune it to a C and the octaves above and below are out of tune.  I've tried it with two different CV keyboards so I'm pretty sure it the oscillator.  Before today I was using it for wacked-out, clanorous FM stuff so it has probably been like this since it arrived from Analogue Haven.

How do I correct this?

Thanks,

Bryan

Sounds like you need to recalibrate the 1V/oct setting.  Being a triangle core, thus not 
having to worry about high freq compensation settings, it's quite easy to do.  The 
proecdure is outlined here:

Nothing lasts forever, you should make it a point to caibrate on a monthly basis.

Hope this helps,
