Hello Pulse,
Today I`m were first time with my XDJ-RX2 on event. I read forum every day and was worried that this problem can occur. I do not have another option except RX2. And magic, XDJ-RX2 froze. =(
Luckily I had second PC running audio from show and I can fast switch to It (additional mixer).
So I used my RX2 as MIDI all event, no USB or another staff. Left Deck was playing, I add next song to Right deck, press play and raise Right Deck volume UP and it hanged.
Is there any info regarding problem solving?
