    I have a Macbook Pro Retina Late 2013 and a Stanton SCS.4DJ setup to use as a midi controller. Since I had this Mac I had noticed that when ever I plug the Mac into an outlet my touch sensitive platters stop working and when I have it disconnected from the power it starts working again. You would think that replacing the USB cable might fix it but it does not. What do you think this could be? Thank you.

    Is the DJ midi controller powered by the USB port or does it have a separate power supply?
