I am a guitarist, and somewhat new to looping. In looking for tools to loop live, I am struck that most hardware loopers (e.g. EDP, Boomerang, RC-20, Gigaedelay) each have their limitations. And some great ones like Repeater have disappeared. In principle, a software based system could combine the "best of" various hadware setups such as sync to a MIDI tempo (like Repeater or EDP), have multiple loops simultaneously (repeater), operating like a delay where loops ca fade (boomerang).
