6 Play the connected MIDI keyboard.
Make sure that your keyboard is transmitting over MIDI channel
1. (Refer to the owner's manual of that instrument if necessary.)
If you've carefully followed all instructions up to now, the "level
meter" bars in the display should move — and you should be
able to hear the sound of the MU100 as you play.
The "level meter" bars indicate the "level" (velocity) of the incom-
ing MIDI data.
These numbers indicate the four Parts of the Performance.
Go on to select other Performances in the same bank and play those
as well. To try out Performances in the other bank, return to step 4
