Reply to Instant delay - how?

Hi!

I've searched the community but has not found anything about how to do this.. I guess it is there somewhere but...

How do I map a button so instantly choose (in single effect mode) an effect, switch it ON, give it a dry/wet value and a effect value, with ONE button. I've tried so many different mappings now, but I can't get it to work!

I guess it's quite easy, but I need help =)
