Reviews and questions about the entry-level MPC500
By schrottgolem Thu Dec 01, 2016 9:36 pm
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?)?

Seems like your tact switch died.

Try Deoxit D5 first, if that doesn´t help you´ll have to solder in a new tact switch. Both methods require you to open the MPC up.
