Hi I want to record audio on ableton from hardware synths and racks, like motif rack, I also have sy85 synthesized and planning to buy more synth racks, what audio interface to buy? Already I have old mbox, but i want to upgrade, I thinking to buy Focusrite saffire 6USB, will do the job? Or I need something with more in/outs, saffire and mixer wil work? To connect my racks, sy85 and electric guitar? What's best stuff to buy? My budged £600 for audio interface/ mixer
