- Space play / pause both
- ← → nudge the fader
- M surprise mashup
- S sync deck B to A
- T master tempo
- QWER deck A drums / bass / vocal / inst
- UIOP deck B drums / bass / vocal / inst
Copying the blend link saves both decks, the fader, which parts are muted and
master tempo, so whoever opens it lands on exactly the mix you left.
