FCB1010 - MOTU Express 128 - Gmajor 2

[J Bucks]

Hello I did this connetion

Computer MIDI Out -> FCB1010 MIDI In, FCB1010 MIDI Out -> G-Major MIDI in

But I would like to pass all the connections goinG IN and OUT from FCB1010 and Gmajor using the MOTU Express 128.

Could someone advice how to do the MIDI Cable connection?

Thank you so much!
