MAJOR CONFUSION WITH EXTERNAL INSTRUMENTS

48 year old dinosaur here…
Your post is indeed a bit confusing…
I don’t have much gear that classifies as classic synths, but my Alesis D4 and Quasimidi Quasar (and my old Roland W-30 that I don’t really use anymore) only have Midi, no USB. I use my old eMagic Unitor8 Midi interface to “control” them.
But I don’t understand why you have a Nektar controller, when you don’t want to use a controller?? :confused:
