I'm just starting to play with GPO. One of the first things I tried was to make a clarinet line that was "expressive". I'm trying to do this with a melody where there are lots of long held notes. My instinctual reaction is to want to bring in vibrato on the sustained notes. But I can't figure out how to do that.
Is vibrato not idiomatically correct for a clarinet? How does one keep whole notes (and longer) from sounding static or boring? Moving the expression slider around a bit didn't seem to help as much as I'd have hoped, but perhaps that's the only option I have? Or am I missing a clarinet vibrato option somewhere?
