Reply to audio4 and midifighter problems

had a few problems toevening when i was trying to get all my gear working together.

basically, i had my audio4 routed into a djm600 (only using two channels) and then had my x1 and midifighter hooked up.

when i was playing i track, i would go to cue jump on the midifighter, but sometimes the audio from that channel would just stop. no lights or owt on the audio4 channel i was using for cue jumping. the other channel would keep playing no problem at all. wierd eh?

ive had wifi and most apps turned off.

any help guys?
