I feel like I'm out of my depth with the Ketron SD2. I picked one up and have it connected and working. But, I don't know what I can do with it. I like some of the sounds I get from it, but others bother me. A case in point, I would like a good tuba sound, but what I get from it is a staccato rendition that is most unpleasant. Is there something I should be doing to get a more appropriate tuba sound out of it?
