ES2 MIDI Mono Mode (MPE) in Logic Pro for iPad
ES2 provides additional parameters that determine the way it responds to incoming MIDI Polyphonic Expression (MPE) data.

MIDI Mono Mode (MPE) parameters
MIDI Mono Mode pop-up menu: Choose Off, On (Common Base Channel 1), or On (Common Base Channel 16).
In either mode, each voice receives on a different MIDI channel. Per-voice channels support pitchbend, aftertouch, mod wheel, and Ctrl A-F assignment messages. See Set ES2 controller assignments. Controllers and MIDI messages sent on the base channel affect all voices.
Pitch Bend Ran(ge) knob: Set a value from 0 to 96.
The chosen pitch bend range affects individual note pitchbend messages received on all but the assigned Common Base Channel. The default is 48 semitones, which is compatible with the GarageBand for iOS keyboard in pitch mode. When using a MIDI guitar, 24 semitones is the preferable setting because most guitar to MIDI converters use this range by default.
