doesn’t have to be used like that. with a midi interface you can set up a tactile midi controller and map the controls that work better that way in the apps that allow it (faderfoxes here)…and sequence it from the OT. i have mine set up on a swan neck attached to the crane stand that my OT sits on…this way the iPad becomes a very powerful partner / feeder indeed for the OT …plus I can use the lemur app with kraftf’s template to control stuff more comfortably on the OT.
