When integrating your Live PA setup with Ableton Live, the Allen & Heath XONE:4D controller is one of the best choices. It has an amazing array of MIDI-mappable knobs, faders, dials and buttons. We had upgraded from the XONE:3D and it has been worth every dollar spent. High quality sound comes at a premium, and Allen & Heath have that conquered. Would love to try some of the new mixers they have made as well. Wouldn't mind getting our hands on a studio mixer too. Great company.
