Great feedback. I'm guessing you had real world experience with a flute, too? Trying to recreate an embouchure in VR is still the bugaboo, but as you guys have discovered, so is avoiding polyphony (only playing one note at a time, to honor the design). You're totally right, notes changing mid-blow is hard as heck (especially when each clip has an intro/outro), but its necessary to maintain the mechanic of 'airflow through valves makes sound'. Discovering I had combos of valve+blow that played NOTHING was a frustrating late discovery, but that was due to my attempts to parse the scale vs. the valve positions vs. the breath octave. (Two full closed notes in every octave with only one note with all three valves open? ARGH!) It's just not as simple as Switch(int, bool, bool, bool)...
I still want to do a post-Jam update, with some UI feedback on the notes we're playing. Should be able to do Taps at the very least... The only thing that would take your lil' Groovebox over the top would be what I cannot allow: Multiple notes at the same time (so both hands could play, but that's just wishlisting on an already cool thing)
Thanks for givin' it a toot!
