"auto" accompaniment (bass, drums etc.) - 1 man band home setup

yes that’s clear, but as an absolute beginner I am not sure which of the equipment is used / how it’s done
(OK I see the drum pad, but could someone give me more details - which equipment and what needs to be setup).
Haven’t listed my equipment, but I have an old Roland E20 synthesizer, electric/acoustic guitar, electric guitar, Yamaha
MG10 mixer, Zoom UAC-8 converter + Cubase LE in case that makes a difference.
