Okay, so let's back up a step or two. Since I don't know you, please don't be offended if the questions appear condescending. I'm really just trying to establish common context for the discussion.
- Are you aware that there is an AX-Edge voice editing utility that only runs on tablets and phones (Android or iPad)?
- Do you have any past synth programming experience?
If the answers to both of the above questions are "no," your chances are pretty slim, as the AX-Edge is not really set up to be easy to learn to program. In fact, it's one of the hardest synths to customize, which is probably why this section of the forum gets so little traffic.
The "Part" level -- simpler -- editing
may be accessible from the Edge's front panel with Menu, Arrow, and maybe a few other buttons. I'm not sure, because I always use an Android tablet to edit my Edge.
The "Tone" level -- deeper and more comprehensive -- is only available through the tablet/phone based external editor.
