Hi! good question! I like your midi foot controller. I have four H9’s but haven’t put together a framework like yours to coordinate them. One suggestion I might have, that could have been taken care of with your pedal board, is the assignment of aux and performance switches for each of your H9’s. I see you have a pedal, and assume it’s configured as an expression pedal for one (or more) of the H9’s.
For now, mine are ‘setup’ with no preset configuration. I’m also not using them with only a guitar. For me, it’s a piece (or several pieces) of studio gear for any use. Although I have several rackmount eventides (H3000, GTR4000, H8000FW), the H9’s have that ‘simply accessible’ nature about them that make effects plug-n-play easy for a wide range of use cases.
