Small question for all you wise souls here on TM. I'm in a drum corps and I'm having to play extremely loud. My tone seems to be okay at these volumes, but the problem is there is a point when my sound just... cracks? I don't run out of air, but the sound just goes ka-put. How do I play at quadruple fortissimo+? I feel like I'm doing it wrong. And (I know this isn't the problem but might as well ask) could it possibly be a gear problem? Thanks.
