Well, that much I know. But there is more to it, and I want to find out EXACTLY how it is working, which was elusive. For instance, when I set a pitch step event, at one point the pitch was changing at ANOTHER step. Other steps can be affected if they are within a certain range. And as I posted, I was very confused about how step events affected the midi channel. Even being confused by how they are working they are cool – but I’d like to use them more predictably.
