Thanks psarkissian. What you suggest retunes both of the strings (in the 12 string model). For reference I think of the twelve strings as Ee Aa Dd Gg BB EE. I'm looking to retune just one of those paired strings. In this case Dd (with the small d being the 12 high octave) to Dg (with the small g being the higher 5th of the D).
Am I missing something in Workbench HD that lets you split the tuning of paired strings in the 12 string model?
Many thanks in advance.
I love my Variax
