“This auction is for an Roland MPU. This unit cosmetically seems to be in good condition other than the normal signs of use. I am not a music guy and I have no idea how this works. I am assuming it needs to be hooked into an amp or something?? I do not have the proper cord to test it. The cord in the photo is included. This item was found at an estate sale and I know very little about it. It is being sold used and as-is just how I found it. ” Link
