Hey guys, I just bought a MPC 500 in a good condition. But I have one problem: I cant use the params button. I know that I have to go into the Sequence to change the sequence length for example. But no matter what I do, nothing works. I also updated the OS but it is still not working. Is there something I am doing wrong? Or do I have to reinstall the OS (if that is the case, how does that work?)?
