ramping this idea up a notch:
With the combination of Helix/Variax, you can create a variety of tunings in the same patch (using "snapshots")

If you aren't a master at navigating a particular tuning, you can compensate by changing tunings with the foot controller as you play through the song. This is similar to using the pedals on a pedal steel to change chordal possibilities.

Each patch has 8 snapshots, so you could program 8 chord tunings into the same patch, and use the foot pedal to trigger them

You can program ANY tuning... doesn't have to be any standardized tuning.. so chords that are typically hard to achieve on a non-pedal steel (such as a suspended 4th) could be easily accomplished using this method
