​Ability to adjust FP via MD3 buttons or MD4 VDIN without accessing FP adjustment screen.

you could possibly replace the FP with an event counter (maybe with math inbetween) and link F1 and F2 to increase/decrease? 

David,

Thank you for your feedback. That's exactly what I am using now but wasn't sure if there is another way I did not consider.

Cheers,

Paul 

As David suggested, the ECNT channel is the way to go.
