Hey @Hawkeye,
Figured it out thanks to your advice! I have an echo going from my Launchpad pro -> Norns. As you pointed out in (c) this is because I have a router turned on that passes Input 1 (my launchpad) out to the Norns. The clock signal being sent from the Loopa to the Launchpad is passing through and sent again to the Norns, and when the clock output for Norns is turned on I'm seeing the multiplication.
Thanks for the help!
