Just when I was about to permanently boat anchor my HD500 due to it's non musical distortion modeling issues, reading the threads it appears that you can use the 500 as a foot controller. Just want to confirm that this is indeed the case? I assume you connect it via the midi connections and tweak the buttons from there? Any way, I paid $399 for the 500 with a $100 off coupon, and it looks like a good stand alone midi foot controller is near that price anyway, so am excited by this potential solution. Woo Hoo!
