Is this true also regarding the tuning of oscillators? I'm an inflexible precisionist with such things.
I think a master tune knob would be a great addition to the P6. Master tune on the P6 is a menu dive and button increment/decrement action. I find it easier to turn a knob and use my ears to listen for the beats where pushing a button you kind of lose that.
Other than that, it works the same as the P5. Ocs 1 and 2 tuning knobs are incremental (1/2 steps) with Osc 2 having a fine tune. This limits your detuning to Osc 1 being perfect and Osc 2 being either plus or minus. To balance the 2 Osc's you need to detune the Master Tune, which is a menu dive (ex. Master tune -01 cents and then a plus fine tune adjust on Osc 2).
My biggest issue with this is that while in the menu other functions are disabled. So you end up diving, coming back out to tweak Osc 2 and then re-diving, etc.
So the detune without menu diving works nice but to stay at A440 you need to get your scuba gear on
