Akai MPC 61 noise

I'm trying to figure out why my noise level is so high(hiss, clicks, white noise etc.) when I track out from the main out puts and when I export to a thumb drive. I haven't been able to get a clean pure sound yet,and when I master the beat it only heightened the noise.Any body knows what's happening?

Got any cues enabled on audio tracks or in the sampler? Better to silence them after.

I don't think so, I'll check and see... thanks for the reply Ultros!!
