OSC 2 Tune

The SYSTEM-1's second oscillator is capable of both fine and course detuning. The tune knob fluctuates between +1/-1 semitone, however here is a way to achieve course tuning capability. 

Make it Course! 

By holding down the RING and SYNC button simultaneously and turning the SCATTER TYPE dial, you can adjust the course tuning of the second oscillator. The UP/DOWN buttons indicate whether you are above or below the current octave. Conveniently, this setting is saved with the preset.
