Nice work!

Map your pads

Select a lane, then hit the pad on your kit you want mapped to it. GM-standard kits usually work without mapping.

Latency calibration

Your kit, USB, and audio output all add a little delay. Press Start, then hit any pad (or drum key) exactly on each click — about a dozen hits. The measured delay is subtracted from your timing so judgements are fair.
