Start from

Hear both. Play it and listen until you could clap the combined rhythm.
Drop one. Mute pulse A or B and play the missing part yourself: tap it, or pick it on a muted string. The circle still flashes, so you can see whether you're with it.
Fade it out. Set "Fade out" on the pulse you're playing. It gets quieter every few cycles until you're carrying it alone.
Speed up. Start slow and let it add a few bpm every few cycles.
Switch hands. Swap the pulses and do it all again.
