Hello I have one Unitor-8 and one AMT-8 connected to my Mac like this: The Unitor is connected to the Mac Modem port, and the AMT-8 is connected to the Unitor-8 via the 9-pin RS-422 port. I need to buy a third interface (another AMT-8). How do I connect this to the other two? (The Mac printer serial port is connected to a MOTU MIDI express to interface with a HUI) Please advice... ___________________ Mikael C.
