Yes midi note would be helpful as would being able to route midi THROUGH to the midi OUT port. Having both midi through and midi out can be helpful but it can also be a pain. I understand that the THROUGH is probably hardwired to the IN but the data should be able to be processed and re-routed via software. If the IN data can be interpreted by the Axe FX 3 so that the Axe can respond to commands it should be able to be sent to the OUT.
