Every time I've been working on a project for a while, I start throwing out the FX from the mixers and I put them in a MultiFX rack, so I have more midi remote CC# available.
Now as long as the FX are inside the mixer, it's quite obvious which track they belong to. It get's harder once the MultiFX is outside the mixer. Imagine, 10 MultiFx racks, nameless in the Livebar and project. I have to search sometimes which belongs where. Some text insert space on a MultiFx would be nice, so we could copy the channel name in there.
