Has anyone had problems playing iTunes back on their mixer ? I have always used iTunes through the through FireWire to ch 17 & 18 but it only plays back through ch . 1 & 2. Capture and Logic Pro does play through ch 17 & 18. I have never had a problem with this before I upgraded to Maverick. I also have a problem with iPad remote shutting down. I hope someone can help me. I've talked with Apple tech support and have tried everything.
