Reply to APC40 send monitor state problem.

I want to reset my filter value with 1 button so I can press it once and the encoder LED is updated to the 'straight up' position. I have tried using Send Monitor State by assigning it to the same button as 'Filter Reset' (and also tried assigning the cc value +8 output to send monitor state) and neither work. Which is the correct way to do this? help!
