I use a IP8 as an extension for my C1500 (when traveling and compact size is must).
What bothers me is the fact, that the IP8 doesn’t act like a “real” fader, meaning it doesn’t follow the mix. I often need to do monitor from FoH in the same situation and therefore use MIX (send on faders) a lot, but with IP8 this doesn’t work.
So a “real” channel fader mode for IP8 would be nice.
