I have a Roland XP-80 and I'm trying to figure out the sequencer. I started off recording a real time drum track in rhythm mode, but when I tried to switch instruments to record a melody the drums that I recorded changed to the new sound I selected.

I read the manual and saw that I need to start recording in perfomance mode, but I'm not sure. Can someone here give me a simple step by step on how to real time record a drum track then switch to another instrument and record that so both instruments record and playback with their own sound? Thanks.
