Connecting Roland MC303 Groovebox to Logic Pro (Mac OSX)

Hello Toolians,

After somehow misplacing it for about 12 years I found my old Roland MC-303 Groovebox up in my parents loft - awesome!! Really want to hook it up to Logic Pro but really struggling to find a youtube video of how to do it. The new Audio Midi Setup thing in Utilities does not appear to recognise the connection - I have a MIDI IN/OUT to USB connection - it flashes orange when I plug it in which I assume means it is working okay.

Any help would be appreciated as I cannot wait to twiddle some knobs...

Cheers
