Having owned a microbrute and only having on knob to tune the synth, the three different tuning knobs is going to be part of my learning curve. I sort of wish the fine tune knobs for both VCOs had a notch to mark the exact middle of the knobs throw so I didn't have to be so diligent about tuning them independently after getting global tuning straightened out. Maybe a firmware update could change the knob behavior (linear/exponential) to improve tuning - Just a thought.
