The eight numbered buttons labeled “1~8” are the Part Selection buttons for each of Stylus RMX’s 8 Parts. These buttons let you choose which Part you are currently editing. The active Part is highlighted in Blue.
The eight small Play buttons under the Part Selection buttons are the Part Play buttons. Press these buttons to start and stop a groove on a particular Part.
NOTE: The Part play buttons only work with the Groove Elements feature.
The eight lights above the Part Selection Buttons are the MIDI Indicator lights. Each light flashes when RMX receives MIDI on its respective Part.
