GoGuitar with an external guitar interface

  • I use an electric guitar with an iRig HD 2 connected to my iPad which works great for stuff like JamUp, BiasFx, etc.

    However when using GoGuitar it seems as if the signal from the iRig is not detected, and as far as I can tell the internal microphone on the iPad is being used, which is not ideal for how I'm using the app (quietly on the couch with headphones on without disturbing others).

    Am I missing a setting somewhere, or are external interfaces not supported?
