Here's a new thread about this subject since I don't see any response from Kemper on the issue to another thread back from 2016.
I need to count in the songs for a band and was hoping I could use the Tap/tempo light on the remote or the profiler, as a tempo guide but it seems unsteady, the tap button is blinking irregulary. Are you, Kemper aware of this issue and can it be solved?
