Question

I have a Presonus Audiobox USB interface. I can hear all audio through headphones in regards to youtube, music, etc. When I import instrumental ( I make hip-hop music, if that can help you visualize what I mean by importing instrumental/beat) I can not hear the beat even though it is clearly playing.

I don't know the specs of the computer.

Answer 1

I suspect that your imported file is not actually a .wav.  It may be a MIDI file.  If this is so, then you need to drop a virtual instrument like Impact on the track so the file and its notes can trigger Impact to generate your drum sounds.

Or...

You need to make sure the Studio One is set to use the proper device.  Your AudioBox.  Open the Preferences/Options and click the Auido Setup.  Make sure the Audio Device is set to the AudioBox.
