Applies to: Xio
Go into the x-gator/arp menu (bottom row, coloured blue). Press the button twice to access 'arp' (rather than x-gator). You can just scroll up until it says 'ARP Notes'. The arpeggiator will only play internally if this is set to 'INT'. If it is set to 'EXT', it will only send out midi notes externally, which you can then record in your sequencer or use to trigger an external device, but it will not produce sound on the synth. If this is set to 'I+E', it will produce sound on the synth internally and send midi notes externally.
