The interface is Alesis IO2 and the keyboard is a M-Audio Prokeys 88.
As well as the interface having I/O Midi, the Prokeys can also do Midi over USB.
Neither seem to work.
The IO2 is setup in the Midi device manager as standard GM Voices.
The Midi port for the IO2 shows as Activer in the Port Setup screen.
The Device Driver is the standard Windows Midi.
Still I cannot see the device as an option in the output for the midi track.
