The X-Air series of mixers contains a handy Amp-sim FX plugin. It's a great option as a backup, for a guest player, or just when you're traveling light. However there's no easy way to adjust the settings or switch channels without going through the full mixing software. X Air-Guitar turns the X-Air amp sim into a 4 channel amp, controllable from your iPhone (or iPad), with support for bluetooth pedals (such as the M-Vave Chocolate, Airturn or PageFlip pedals) to switch channels. The app is not affiliated with Behringer in any way
