Hi

I'm having trouble setting up midi to work as I would like it to work...

The set-up I have is fairly basic - an E-Mu X-Board 25 controller
keyboard, a MED and a PC running Windows XP and a Carillon 1 in 1 out
midi port.

Getting the keyboard and evolver working together is easy enough
(midi-out of the X-Board to MED's midi in) and I can get get my PC and
the MED working together (midi-in of MED to midi-out on the midi port
and vice-versa) but I can't figure out how to set it up so I can control
the MED from the X-Board and the PC at the same time?

Is it simply the case that I need a midi-port with more in and out-puts?
Or can I get it working via midi-ox or, or, or???

Any suggestions welcome!

Paul
