I purchased a 2nd hand Karma V2 Workstation with EXB-PCM08 board installed. The keyboard is working 100%, but the expansion don´t.
I tried to change the EXB from slot 2 to 1 and vice-versa. Nothing changed. The board is not working.
I perceived that EXB-PCM08 is not showed in Karma display when it´s turned on. When editing some program, the samples from EXB are not listed. So, I think this expansion board is damaged.

Anyone have some idea?
Thanks in advance!
