Reply to Looking for QUICK answer. Leaving in an hour for gig!

Most likely simple, but I'm a bit confused looking at the mappings. I'm using 3.6 (?) mappings, and I want my "echo" button on my VCI-100SE to be .. well ECHO again... it's currently mapped to Gater. Just looking for the option in the settings to change it from Gater to ECHO and I can't seem to sort it out.. I love to hold the ECHO and hit the platter for that echo out effect.

Quick help? Thanks in advance
