RME-HDSP9632 - EXP MIDI I/O ??

Does any one know if theres a expansion Card for more midi ins/outs.
My problem is that i have a control surface(mackie-Control) and a keyboard (Yamaha-Motif)
And this PCI Card Only Offers 1/1 out midi interface but i need 2 does any one have suggestions
Has any one got any ideas so i can run both midi i/o into the card.
Would a midi merger work ?? (Midisolutions) any one got one????

If any one can shine some light on this . thanks in advance.
cheers
