Reply to MIDI Cutout on VCI-300

The last few gigs I've had trouble with my previously great VCI-300 (w/Traktor). Seemingly at random (although once it was with a pretty heavy bass drop), I lose all MIDI control, often accompanied with a quick burst of static or the lights blinking. The music keeps playing, which is the strange part, since I'd assume that any trouble would take out the internal sound card as well.

I've ordered the AC adapter for it, in hopes that it'll alleviate the problem, but definitely no guarantee there - has anyone experienced this before? Any ideas what may be causing it or solutions?

Thanks DJs
