These controls simulate what a DJ manages every transition. The harmonic compatibility indicator (centre) reflects whether the two loaded keys work together — 8A and 9B are a tension zone: technically compatible, but with an edge. On Open Decks, challenges are designed around exactly these decisions — without requiring any hardware.
