For ease of carrying and setup, it would be awesome to have a full Kemper in a footpedal only format. This can then be carried in a bag, placed on the floor, cable it to powered speaker or direct and bam, you are done. No other device needed... No extra footpedal, no other device, nothing. Kemper footpedal to FOH and you are done.
Many of us do not have big rigs or play large venues. Would be great to have simple footpedal only kemper...
