So I was toying around with the tutorial lessons in the beta since I figured I'd try those out after all the updates out of curiosity, and when I got to Big Band, I had an issue with that trumpet Za Wardo thing. After the first time you're told to do it, the very next lesson I can't seem to do it. What happens is that he just whips out the trumpet and I'm unable to do anything and he just drops it. Even when I hold MP, it doesn't extend and let me perform any notes. I'm not sure if I'm the only one with this issue, but I'd figure I give a heads up for anyone who wants to confirm that its not just me.
