The SYNC I+II is labelled confusingly.
The 'I+II' is closer to the black waveform rocker than the SYNC button, in line with the labels of the bottom parameters, implying that the bottom waveform black rocker relates to channels 'I+II'
V2 had 'SYNC' and 'I+II' very close to the button.
Move 'I+II' closer to the button it refers to, away from the rocker, or just remove ''I+II' altogether, and label it like the 'Link' button.
And, not so importantly, just a visual element... Channel II 'MIDI SYNC' label is way down below every other label, for no reason. You have so much room above it, button and label can be raised up.
