Expression Out?

Hi - just wondering … if the expression jacks on the MC6 are now able to send Midi out.
Is there a reason they can’t be used as Expression outs on a future firmware update?
So one could act as an Exp In & the other as Exp Out.

This would allow for the use of a single expression pedal to be used as a midi on the way in and still be able to be sending expression msg for a non midi pedal with exp…

Does this make sense?

Is there a physical hardware limitation preventing this in a future update?
Thanks

unfortunately it can’t be used as an expression out because it requires a different set of electronic components for that

thanks for the extra info James!
