I've been pulling my hair out trying to figure out why I can't get any modulation FX to side chain into a vocal channel. I can load up any reverb no problem into the FX1. As soon as I try Flange/Chorus/Phaser, I get nothing. Routing looks correct, meters are moving its receiving signal. There seems to be something inherently different about Modulation FX that I'm missing. Sorry if this is the wrong place to post, and I'm a bit of a beginner
