ok So I have an MC 6000MKII, MC 4000, and an MCX8000. When I use the MKII if I have a loop set, I can hold the shift and the pitch bend (+ or -) and it will jump to the next segment of the song with the loop. (I'm really trying to find a better way to describe it) If I have a 4 sec loop from say 2:30-2:34 and hold shift and the + sign it will play a loop from 2:34-2:38. How do I do that on my MCX and 4000? BTW using Serato
