Problems 8out MPC 2k classic

Sometimes when I load a ASP file my MPC sounds bad on every second aot of the 8 outboard. It ist a orgina ADO II fpr the MPC from Mutec. Has anyone a idea how I can repair it?

thx

i might be able to help you if you made a bit more sense...

The problem:
Sometimes when I load a .asp file every second out of my 8 out board sounds noisy. The stereo-out sounds normal.

When I reload or restart my MPC the failure could be away or not.

Thx
