An "Instant Access" Tap Tempo on my GCP

[MatthieuTelegraph]

Hey everyone !

I'd like to control the tempo of my delay pedals (a Flashback X4 & an Alter Ego X4 Vintage Echo) directly from my GCP with an Instant Access button. I've tried different things but didn't succeed. Any ideas ?

Thank you for your help, cheers from France !
