As informed by Peto, the looper feature is exclusive to Remote and cannot be accessed by other users, as per this link:
http://www.kemper-amps.com/remote
Since the looper is inside the Kemper, couldn't all users have access to it? If not the reverse and half time buttons, at least the start/stop functions? Shouldn't this be a simple case of sending the appropriate CC numbers? If not, couldn't these features be mapped to CC numbers so that every user can access them?
Hoping for a favourable response to this request.
