I have purchased a Moss Exp board from our supplier in South-Africa for my Triton. He has sent me a Moss board for a Trinity. My question is "Is the Trinity Moss board compatible with the Triton or does the Triton uses its own dedicated Moss board?"

I'm not sure that you may find the answer to your question here on that problem you have.

You should e-mail Korg USA.
