Greetings to all in Kemper World!
Stage user here.
If the Tap button is assigned to an effect or stomp, it would be most helpful if the Tap LED would indicate on/off status.
That being said, the same request would also apply when assigning stomps/effects to the Looper and/or Tuner buttons.
I know this has been requested before, so my apologies for any redundancy.
But now, more than ever, with each addition of more effects/stomps, this is becoming more of an issue. And it will only continue to be exacerbated with each new update that includes any additional presets.
Caveat: This wasn't an issue for me UNTIL the latest release of Fuzzies! Now I'm addicted to using the Preamp Fuzz preset as a boost/od and needed a button to assign it to so I had to assigned it to the Tap button.
Damn you CK for making this ridiculously great machine even greater! 
Thank you for all you do!
