The iConnectMIDI4+ ‘host port’ will support any class compliant MIDI device. If the MIDI interface does not require a special driver from MOTU, you should be good using the ‘host port’. Just keep in mind that the iConnectMIDI4+ is actually hosting the device, so you would not be able to use any integrated software or editor MOTU may have for the interface - since the hardware will not show as physically being connected to the computer.
