Check your Gain switch on the front of the mpc next to the record gain knob, make sure the switch in the back is set to line input in you are using a audio mixer instead of your record player directly in and disconneect and reconnect just the audio in on your 4k and the audio outputs on your mixer just to double check if you f up most likely. And lastly look at your users manaul to check the proper way to hook up your studio.

Each time I change I triple check everything most likely you are getting feedback cuz you f up.

Happens to all of us time to time.
