Bend Range- Globally sets the pitch bending range of the entire instrument from 0 to 12 half-steps. It may seem silly that there's a 0 setting, but it's useful if you'd like to use a MIDI controller pitch bender and the Pitch Bend CV out jack to control a parameter other than pitch. In this way, the pitch of notes is unaffected.
Master Tune- Tunes the entire instrument down or up by 100 cents. Useful for jamming with the tuning-impaired (or a piano).
