Hi Andy, you are correct. Through the tempo menu, there are 6 sound options that include 2 drum kit kicks. They do a basic 1, 2, 3, 4 or subdivision of that.
My approach is quite different in where you can pluck your guitar strings, that triggers a kick/snare/hi-hat sound (by using synth + drum samples as impulse response). This allows you to do any beat/rhythm which I use in loops and jam against.
