I am getting sound distortion after using it about 1/2hr or so. I am running the latest firmware and i am running Yosemite 10.10.3 on my mac. Not high sierra. Just purchased this controller so need some help.
Have you contacted Tech support yet?
Are you using Serato? It this just a new controller (i.e. have you worked with this laptop with this DJ software before with different hardware?)?. Does it always do it and always after about 30mins?
Distortion that gradually starts and increases can be connected to buffers filling up and such. And, bar hardware failure in the controller, is usually connected to things like latency. Playing around with those settings might help matters.
