hey j.g.!
make sure you have the detune knob turned down to zero, since it
detunes osc's 2 and 4. i tend to forget it from time to time.
it is normal that when the effects are on' that it is in tune, since
it syncs osc's 2,3 and 4 to osc 1 (single mode) or osc 2 to 1 and osc
4 to 3 (double mode) and therefor it's only osc 1 or osc 1 and 3 that
matter.
cheers!
