Actually uses the newer Expander with USB-C for the F8R, purely so it can be configured on the computer, or on the rare occaision, be used to control the computer in some way.
Midi directly connected between F8R and ES-9, configured for standalone mode, channels 1-8 volume input gain.
Looking at modifying setup to use the KIWI so I can add "Pan" to the setup, bigger case required.....
