Reply to Echo button turns on gater, not delay

Howdy,

Just purchased a second hand VCI100 SE (one that has been about in the DJTT community; previous owners Karlos Santos and the very courteous paulmac).

Anyhow, my echo button seems to be mapped to turn on the Gater effect, rather than delay. I know I can sort this out in the mapping, but I'm pretty new to this and was wondering if someone could tell me what I need to do so I don't ruin everything!

Thanks very much.
