I noticed tonight that the knobs show Vocal / High, Harm / Mid, Drums / Low usually.
They have now started showing %ages when adjusted as well but sometimes you’ll see a %age and twiddle the knob again and it goes back to showing the words!
It doesn’t matter where on the knob you set it so it’s not linked to 0 / centre, it’s just all over the place.
I’ve uploaded a few pics taken within seconds of each other that hopefully show what I mean.
No major issues with operability but seems to be a bug nonetheless.
Quick edit - forgot to say iPad Pro 11” (1st gen) and using on-screen controls with no midi device attached at the time.
