No Noise pot and no banks BCD

I bought a Voyager from ebay and after the excitement of it arriving plugged it in and the noise pot was not warking at all , and there was no banks BCD the os was 3.4 , i plugged midi leads in to load os again and then noise came on permanently when keys were pressed the noise volume pot did not respond at all. On trying to reinstall 3.4 in the correct order BACD the voyager would always ask for bank D after bank B , so i’ve sent it back to the guy i bought it froms tech , but i’m worried can anyone shed some light on this ?

If the Voyager was a pre hardware 3-x one, it does only feature on sound bank. No matter what OS you use.

I would rather load in a patch that is from a source you can trust to see if maybe there is some wild pot mapping or other strange programming things going on in the Voyager that cause it to work different from what you think it should be like.
