cmc qc midi activity spiking

So they missed a chance here.

I know that my beloved old Kawai K4 - I use that nowadays only as a keyboard, but no more producing sounds -
emits all the time MIDI active sensing - that drove me crazy, when I wrote my own MIDI processing software
but I never saw that in Cubase - since Cubase 1.0 on my ATARI ST.

Why is it so difficult to put a filter into the driver?
