Recording into CPU using acid 4.0

Im trying to record into my computer a beat I made or any other beat I made from my MPC1000 and I always hear a BUZZING noise how the hell do I get rid of it, my connections are good what could be the problem and any reccomendationds for programs to use to record from the MPC1000 to the CPU for the best sound quality. Thanks!!!

the buzzing you hear is most likely your cables or piss poor samples or sorry soundcard the list is endless sometimes if you jiggle the cable the right way it will stop, was the sound buzzing when you brought it in? using a noise gate can get rid of most buzz depending if its dry, meaning not a lot of effects like reverb which needs time to start up. a good software for recording your audio is protools cause thats all i know, but a few players on here mess with a lot of different gear hopfully they will chime in. also shitty cables will produce shitty results invest in a good set and forget it.
