I also posted this in the thread all about this problem. I'm starting this new thread for greater visibility.
I may have found a "fix" for this problem. It seems to be related to this new "feature" regarding how the KSP "samples" the Tap Tempo button.
Go into the Utility Menu on the KSP. Scroll all the way down to Misc and open that. Scroll down to Step Listen and enter that.
Turn OFF Step Listen. Save and exit the menu system.
This appears to have fixed the problem for me. Does it work for you?
