• Is the USB cable connected correctly?
• Are the volume settings of the tone generator, playback device, and
application program set to the appropriate levels?
• Have you selected an appropriate port in the sequence software?
• Check whether the MIDI IN/OUT setting in the Utility mode corresponds to
the terminal/cable actually used (USB or MIDI) (see MOTIF-RACK Owner’s
Manual page 61).
Playback response is delayed.
