Help with sample method?

Im trying to get my setup to run samples from the turntable to the MPC Ren but dont know the configuration. theres no recognition on mpc software. Been using audacity to go from aup to mp3. looking for more efficient aka direct ways of doing this. Im familiar with FL studio but still cannot get the sample directly. Any suggestions?

If your turntable is running through a USB interface (or via an interface and into the computer using USB), then you should be able to select it in the MPC software under Preferences/Audio
