Don and I have recently traded a few posts about using a Ketron SD40 with his OAX800. Maybe you have been following along with some of the comments on other posts? He was able to solve his issue before I had time to get back to him. More to come on that in an upcoming post or two.
Along the way, he shared a picture of his setup. Sometime in the next week or so, I’m going to go through both the config he sent me for OAX and his Ketron and possibly put together a short video for folks that might be interested in doing the same thing. For now, check out his setup – Very Nice!
