Update: I have this all worked out at this point. I used a volume pedal that is on for rhythm guitar tone and it has the volume set a few Db lower than normal, assigned it to a foot switch along with my delay and noise gate so that the volume pedal turns off when I hit the switch, which causes the volume to go back up to 100%, the noise gate turns off, and the delay turns on. I still switch between patches when I go to clean and back to dirty due to not having enough effect blocks to accommodate both tones within 1 patch.. Now I need to change my MIDI events so that instead of changing patches for the lead tone, the events activate the foot switch. Joy!
