Why are my oscillators out of tune?

Over time, Grandmother’s analog oscillators may need to be recalibrated. To do this, enter Global Edit Mode by holding the SHIFT and HARD SYNC buttons down for one second. Then hold down all three buttons on the Left Hand Controller and press the lowest note on the keyboard to start Oscillator Calibration.

NOTE: This process can take a while, so never do it just before a gig.
