that is a great idea! never thought about that...I use to external switches on the MFC, I have Midi CCs setup for these. Turn OFF both the "Midi RX Channel" and the "Midi RxProgramChange" on the MFC. I am connected to the Axe-FX using the ethernet cable.
On the Axe-FX, I am setup w/the default settings, except you need to turn on the "Midi Thru/Out" setting. I have a 5-pin midi cable connected from the Axe-II Midi Out/Thru connector to the Midi In on the Motif ES Rack box. Everything is set to Receive/Transmit on Midi channel 1.
All I can say is this works for controlling external gear from the MFC/Axe.
so you have the CAT cable to the Axe fx and a Midi cable to your Motif at the same time? And can you still use Axe Fx mode?
And control the other gear using the external switches? So pressing an external switch giving you 17 IA switches to control your Motif so the say? not sure if I really understand this correctly.
