Buzzing sound
-
I use Bias FX on my iPad and acces it through a Melaudio MIDI commander pedal. I have a usb that goes from the iPad to the pedal, and a second usb that goes to an audio interface. Very randomly I get a buzzing sound that distorts whichever setting I’m on. I never know when it will happen or why. When it happens I have to power the ipad off then on again. As I would like to use this setup in a live setting, does anyone know why it happens, and more importantly, how do I stop it from happening?
