I’ve got a Pioneer DDJ-SX that’s been having audio drop outs one fader 2 that are confirmed to be fader related. In the interim my work around is playing on lines 3 and 4. Audibly this works fine, but visually those faders don’t send visuals. 1) does ME work in 4 deck mode or 2) can visual lines 1 and 2 be touted to get a signal from 3 and 4 Thanks!
