I have the FCB with EurekaProm and not sure that it will work as the FCB basically is now a dedicated controller for the KPA. You could probably replace the EurekaProm with the stock Eprom and then program it to run into the Motu and then send midi info to the KPA. I could be totally offbase and if so would like to hear from others as well.
I really don't want to remove the EurekaPROM because I love it and everything is programmed for me through it. I'll research a little more and kinda figure it out. But thank you so much for replying so quickly. Have a great day and God bless,
Craig
