4. OPERATION

4.1. Master Controls

These controls are always active, and they're not sent out or received over MIDI.
• Master Volume - The synthesizer itself will not distort with the level all
the way up; the control is only to avoid overloading the next step in the
chain (mixer, audio interface, amp...).
• Phones - The headphone level is independent of the Master Volume.
• Fine Tune - Global tuning ± 1 semitone from the knob's center detent.

4.2. Utility Commands

Pressing Panel plus another button invokes the following "hidden" commands.
• Panel + Kbd Track - Auto-tunes the instrument. Because voltages drift
over time - which is part of the character of analog synths - it's
necessary to tune the instrument occasionally, more frequently while
it's first warming up.
