MIDI Control:

Off

—

When On, the synth will respond to MIDI

controllers, including Pitch Wheel, Mod Wheel, Pedal, Volume.

MIDI Sysex:

MID

USB

—

When set to MIDI (

MID

) it will receive and

transmit them using the MIDI ports/cables When set to USB it will

receive and transmit them using the USB port/cable. MIDI SysEx

messages are used when sending and receiving a variety of data includ-

ing, programs, alternative tunings, system updates, and more.

MIDI Out:

MID

USB

—

Sets the port by which MIDI data will be transmit-

ted (MIDI or USB)..
