More likely a buggy firmware of your USB audio device :)
From the driver implementation POV, both audio and MIDI devices are
handled by individual endpoints, hence they shouldn't conflict.
Or another possibility would be some USB host side issue like the
bandwidth. But it's a MIDI stream that is very low data rate, so this
sounds also unlikely...
