Hey guys, I'm trying to mess around with the loop recorder on my s4. I'm currently using DJTT's S4 Mapping and I found that when I'm switching the record source from Main to AUX, it doesn't record anything. (no sound coming out even when I routed the input aux to ch D) I restored to default S4 mapping and now, it seems to be recording from AUX just fine, but NO effects are being recorded. I need help! I was hoping to be able to record vocals with effects using the DJTT S4 Mapping in the AUX mode on the loop recorder. Main works just fine, but I don't wanna record all the decks that are playing :/
