I haven't gotten a reply from eventide support yet but I did do a little experiment. I made my own midi cable that splits the midi signal from my efx out to the three factor pedals (no daisy chaining, no midi thru). Works fine and clears up latency issues and dropped midi messages. So, that thru box from midisolutions is most likely just the ticket. Or you can hack up a cable like I did and see if that works for you.
