Build 3176 introduces MIDI Filter button and indicator for MIDI Route and Plugin slots.
The little indicator lights up green when there is one or more enabled MIDI Filters:

Hi Brad
I’m not seeing the indicator. I don’t think I’m using any kind of custom theme. What’s the trick?
Hello!
A little bit feature request here 
It would be great to add a transpose indicator (showing amount of transpose in halftones)
Am I alone? Anybody? 
kind regards, Alexander
Hi Alexander,
This could be done, but in general I tend to advise against using the MIDI filter transpose item. MIDI routes have there own transpose setting which is displayed in the MIDI route slot, behave better with state changes and can also be controlled by states.
ie: use this setting in preference to the MIDI Filter transpose item:
