Sorry, I should have been more clear. What I meant is that you don't need to do any editing of the preset files when going between the two – Width will take care of itself.
As far as exporting: Presets saved in H9 Control will not automatically appear in the iOS Files App. You'll have to export them as you normally do from within the H9 Control app. When you later import them into the Files app and place them in the "UltraTap" folder, they will appear in the UltraTap iOS app.
