Actually, then you only need to put "Noise" in the mix section a bit down and the OSC 2 pot a bit down and everything would be nicely aligned.
Speaking of external input, there is space for one more button in the Modulation section and that could be "external in" modulation button.
Some more ideas: in "Voice Variation" section there is some perfect space for one more knob. How about "Drift"? A little randomisation of both oscillator's pitch?
Speaking of oscillators, there is enough space in the oscillator section for one more knob or a button. Maybe that could be a "DC Filter" button? Or even a knob, so we could fine tune its strength?
