Hope someone can help me with this. I set up some presets on my VARIAX CUSTOM 1 in MODEL Setting in workbench which had alternate tunings. Martin in Double Drop D, Gretch in Double Drop D, Banjo open G, Dobro open E, and a Firebird in open A. When I am connected directly into my DT 25 with a regular guitar cable my models come up with the alternate tunings like they are supposed to. When I connect my VARIAX through my HD 500 with the VARIAX Link Cable the models are there but the alternate tunings are gone. Could not find anything about this in the manuals.
