Ok, I've decided to dust off my HD500 and use this as my pedal and effects board thru the effects loop of my amp using the 4CM. I haven't gotten that far yet, I just got the HD5 out again, literally dusted off the cobwebs and updated all the drivers, patches, etc. I then created a few new programs after the "firewall" thingie (effects section of the amp), selected FX Loop, then say Reverb, Chorus, whatever. I added a Wah in this area, and the pedal functions fine, I can sweep up and down and see it move in the programming. However I try this as a Volume pedal and I get no movement, no sweep. I did the Vol Pedal re-calibration following I think it was Dave (or Steve's?) video instructions on YouTube, got that straight, tried again, still no Volume pedal. When I try a pre-built model from say the Best of HD500 the Vol Pedal works fine, and I move them into the effects loop section and it works fine. But when I try to insert into a program I get nothing... So, sorry for what maybe a very basic question but I thought I'd ask and perhaps save myself a lot of troubleshooting grief...
