Assigning Soft Rotaries and Key Function.

Hi, I’m on the SQ7 which has the Soft Rotaries. I’ve managed to assign the Soft Rotaries as channel volume control using “Send Level Fader”. My question is how do I assign the Soft Key below the Soft Rotary as a MUTE button. I assume you’ll need to use the Key Function but the only choices on Key Function are Assign and Unassign.

Thank you for your help.

OK, I worked it out, I had to use Main Level Fader and not Send Level Fader. DOH!!!
