Thanks!
Yeah, it was just me. It took me a couple of tries - with a metronome
in my ear - to get them to line up okay; I don't know how anyone can
do that with, like, a multitude of parts. It was actually very
awkward. It was like hit-record-get-fingers-back-up-to-flute on beat
one, breathe on beat two, play on beat three. I'm not sure if there's
a more convenient way to do that, but it seems like there must be.
