This shows again how easy it is to switch from the original FX guitar RealTrack to the Direct Input version adding a VST FX like Amplitube.
You don't need to regenerate the track in a DI version giving you different riffs, this will change instantly keeping the same riffs.
You can't do this with a consolidated rendered wav file from Biab.
