Thanks you everyone. Yesterday I've tried to play with my controler and its very cool to play with the delay for example (auto-oscillation, like with analog delays), and to have access to all parameters. It can be used without H9 control app. The EXP pedal control the Whammy (PitchFlex algo) : The sound is awesome.

Well, my H9 is ready to go on stage with me.

It could be cool that Eventide produce this, I will be so proud :).
