Single Status Update
First, my apologies if I interpreted your original post the other day as anything but genuine frustration with getting Helix to work... sometimes it's hard to distinguish those who are really looking for help, from those intent on stirring the pot. So again, my apologies.
You mentioned above about warming up the tones and attack... lowering the input impedance (found in the input block) may help with that. I used to do that quite a lot with the 500X, not as much with Helix, but I have a couple of patches where it helps. Lowering it too much gives a kinda "dead" sound, and sometimes it won't play nicely with certain FX, but its worth a try.
Hope that helps.
