ES M offers three additional parameters that you access by clicking the disclosure triangle at the lower left of the interface.
Extended parameters
Pos. Bender Range: Set the upward pitch bend range in semitone steps. This lets you use the pitch bend controller of your keyboard to bend the ES M pitch.
Neg. Bender Range: The default Neg. Bender Range value is Pos PB (positive pitch bend). In essence, this means that only positive pitch bend is available. Set the downward pitch bend range in semitone steps by up to 2 octaves (a value of 24).
Tune: Tune the instrument in cents. One cent is 1/100th of a semitone.
