Hello

I just purchased an H90 as well as an H9. I would like to control the H9 with the H90 control app on my ipad.  Is this possible? and if so would I just use patch cords (stereo to stereo) the h9 into the H90 and then add it to the H90 control app?  Or would I have to route it in like a non-eventide pedal…?  thanx      –  looking for a You Tube vide demonstrating this  thanx again
