I have A guitar hooked up to a presonus audiobox then usb out from audiobox to iPad Pro via lightning cable.
Everything works fine. I can get MG2 to work alone, with AU plugins, midi out to audio bus etc etc etc.
BUT, semi randomly I get a loud static (like a tv trying to time to a non existent channel). It only lasts for a second, and seems to occur around every five minutes.
There are no loose or cheep wires/cables in the setup. The guitar works totally normally with other applications (real amps, DAWs, etc).
Has anyone seen this behavior?
