My advice is that you do exactly that, put the combo on stand by, at least while you wait for an answer from somebody who can actually help you.
Something I would do too is to create/edit the patch, let's say "without the amp", and by that I mean using just the modelling, and when you're happy
with the overall sound of the patch, being less likely to have to move blocks, plug the HD to the amp and tweak further
I have to remember that this community is made up of musician that apply these tools in many differert ways. Im a bit old school in plug it in and play. I gotta hear to know if it works. I dont use any other vehicle for monitoring. Even if you did it would not translate to live sound. That is by application for my setup. Well the amp,,,, she is not so inexpensive so I will be carefull... just more getting use to the new way of producing my minds sound!
Thanx for you time
