the mini midi breakout module (only 2hp) has multiple i/o (3 of each iirc) so can be used by both the es9 and the disting simulatneously, you just need the right ribbon cables and the right midi adapters
otherwise you could make custom cables to connect midi cables to idc conndectors... but the module solution above is probably a lot easier and cheaper!

Utility modules are the dull polish that makes the shiny modules actually shine!!!
