This is likely a dumb question, but is it possible to use plug ins on an external midi track? I have been using soft synths for years and now would like some analog hardware synths. If I connect the synth through usb, will I be able to eq/compress/effect the synth with plug ins? I don't know if usb controls midi only, midi and audio, I'm completely in the dark. If I connect the synths through usb will I still need some kind of audio interface for sound to go through? Also how well integrated is the automation capabilities of Logic Pro X and hardware synthesizers? I am considering the Novation Bass Station 2 and Arturia Microbrute and thinking how awesome it would be to record those knob twists. I have Logic Pro X 10.1, haven't updated to 10.1.1 yet. Thanks.
