Hi, not sure if this is still helpful but I figured out how to do the bank changes easily in Logic Pro X using SysEx data with custom bank messages.
It's fairly easy if you know what to do.
You need the SysEx data for a bank change of the FB-01 which is F0 43 75 01 18 04 xx F7 (xx = 00 to 06 for the seven banks in the FB-01). (I have to say that this is thanks to the monitor function in the FB-01 plugin of Midiquest). Otherwise I wouldn't know what the bank change Sysex data for the FB-01 would have been.
Then convert this Hex Code into Decimals: 240 67 117 1 24 4 x 247 (x = 0 to 6)
Then go to "Define custom bank messages" in the Midi Environment of the Multi-Instrument (FB-01).
Delete all Control Bank messages.
Add a SysEx message. Paste the above decimal code. (the final 247 gets converted into EOX automatically).
Lather, rinse, repeat for all banks.
Done.
At the end it should look like this:
