I read this before purchasing the unit.
'The AMPLIFi v2.1 firmware update turns AMPLIFi 150, 75 and FX100 into powerful class-compliant USB interfaces for Mac, PC and iOS*, making them ideal for use with GarageBand®, Cubase®, Pro Tools®, Logic®, Ableton® Live, Cakewalk® and other pro recording platforms. All AMPLIFi owners can now record with the same exact amp and effect tones they’ve downloaded from the cloud or created themselves.'
Does this not mean that it works as a stand alone USB interface?
