This is a great app.
But the tuning vibrato trick needs a little tweaking- it likes to play out of tune, there needs to be a bigger sweet spot for the pitch center.
Please please please make the pitches transposable to Bb, C D Eb and piccolo A & Bb!
This app would be so much better for practicing if it had that feature.
For the piccolo trumpet there are four valves and slightly different fingerings.
Have you experimented with "lead" trumpet notes? What If you hit high c maybe the "smear" trick would take it up to the altissimo range?
