My X7 has a parallel out that I use for the Key Input, which is ideal but not everyone has that option I guess. I don't use it in an effects loop, can't stand them, it isn't necessary. Also not suitable, I need my gate before two pedals on my board for various reasons, and I DI out to FoH from my board, loop will mainly be for guitarists using their head for gain.. But yes, its $$$!
