Just start asking questions....myself as well as the guys here on the forums are more than willing to help. One suggestion though is for you to read through your manual page by page. Experimenting with everything that the manual is teaching on your mpc as you read.....if you don't understand something in the manual post a question here in these forums for some help....like I said I am more than willing to help where I can.
Have fun and congratulations on your new mpc 500!!!1
