Sub 37 Request: Duophonic Arpeggiator

I would love to see an arpeggiator mode for the Sub 37 that uses the duophonic capability.

Even something simple such as this example with 4 notes:

1st beat: Notes 1 and 2
2nd beat: Notes 2 and 3
3rd beat: Notes 3 and 4
4th beat: Notes 4 and 1

What do you all think? Good idea? Any chance of this happening?

Please tell me it will have TAP TEMPO!

I like the idea of having a duophonic arpeggiator! Good suggestion.
