If I calculate when they ' re closer , the benefit of the EM drive us further reduced <| sep |> If you get an interface with enough inputs it ' s pretty easy . For every instrument outboard effect you have you can create a new track in ableton and select the corresponding output channel from your interface as the input for that track . If you want to midi control the instruments from ableton instead of playing them live just add an external instrument devicein ableton instrument section to the tracks you want to control . Then in the external instrument device select the place you want to send your midi to , and the corresponding output from your mixer in the audio from section . Of course to send midi you will need to get an interface that has midi out , or get a separate Usb to midi controller . I got a 1 x 1 usb to midi for like $ 20 .
