Make USB audio available as an FX loop.

    I use Roxsyn guitar synth and midi guitar 2.0 apps on iPad when noodling at home. I would really love to use them live but turnong them on and off during performance is a bit tricky. It would be great if the USB audio feature could be added to the FX Loop as this would allow me to put guitar synths/midi devices and playback from iPad audio into a footswitchable format.

    until something like this is implemented you might try a cheap Bluetooth controller for the iPad. I believe you can pick something up like the chocolate mmWave for 30ish bucks. I use an irig blue board for this purpose and just mute the output of the synth with the controller and bring it in and out when I want to.
