Asio Time Overload issue using Korg padKontrol

I am using my Korg padKontrol connected to my PC through the USB port to play Superior Drummer 2.0.

When I play the padKontrol, the “midi In Activity” indicator is high and the “Asio Time Overload” indicator is lighting. I only have 4 audio tracks running and no plugins or hardware inserts, and when the padKontrol is not being used nothing is overloading. So, I don’t know why the padKontrol is causing an overload.

Is this a Cubase fix or a padKontrol fix? The padKontrol manual didn’t address ASIO overloads. So, I thought I’d ask here.

Thanks to anybody with useful information.
