I was just playing around with workbench and HD edit and I thought of something I think would be a cool idea.
Add HD500(X)/JTV functionality of assigning controls to certain positions of the JTV's pickup selector.
For example you could assign a distortion box to the bridge position of the JTV patch. When you switch from the neck pickup to the bridge pickup it automatically would turn on the distortion box.
There are countless more examples you could use with this functionality, but I think this explains it.
If anyone thinks it's a useful idea here's the link to the ideascale page.
