Hi,
OB6 shows strange behavior: its pitch is one full note below my other instruments, so playing a C on my OB6 translates to a C# on my other instruments. I tried to run through all OB6 settings, (most obvious one being tuning table at norm and Master Tune at -01) rebuilding calibration data, checked, VCO freq, yet problem persists. I don't know if I am missing something obvious or is it a serious problem?
