Logic: Cascaded Emagic Unitor 8 or AMT 8 interfaces may not be recognized
In setups where there is more than one Emagic Unitor 8 or AMT 8 MIDI interface, sometimes only the ports for the first unit are recognized by the system.
When you power up multiple Emagic MIDI interfaces, be sure to power up the unit connected to your computer last. If all the units are not recognized when you power up, make sure all the units are turned on, and then power cycle the first unit.
