Reply to Problem with Gater Effect discovered during show.... HELP!?

Hey everyone,

Last evening was my first show using my S4... I've had it for a while, but weekly performances are just now starting up for me.

While I was playing... I went to use the gater effect. I was using the 2 decks + 2 sample decks setup, and I had my A and B decks set to use the effects from both 1 and 2.

Ran into the following problem:

When I selected gater from my FX list, it automatically turned on and was maxed on all parameters of the effect... basically ULTRA-gatering my current song.

Luckily... it didn't sound too terrible... but I can't ever remember the effect doing this in the past when runnin through sets. Is this a setting that I somehow turned on or off?
