Also Vinny, I've said this in another post but in your case- for your RT's jazz composition, let ALL of what happens just happen. Give full control over to what generates [or regenerates] from your chart. If it doesn't or can't match what's in your head, go with the flow of what's happening anyway. There is some control over RT's, as has been mentioned. But let your bass notes and fills go and work with what's generating from your chart. It's not only liberating, but I'm finding there's performances in there that out-write what I had in mind. And it'll save some frustration too. Let the guys play your chart *their* way. With jazz especially, RT's are raising my eyebrows a bit! LOL!
