I use a Creative MIDI interface (looks very similar to the Roland) with Norns and it works fine. In order to get it connected to the DAW on my computer, I need to plug the Creative into another MIDI interface that has the female 5-pin DIN connectors. But if you have a synth with the 5-pin inputs, it should work fine by itself.
Make sure you using the right 5-pin connector. I was confused by which is input and which is output, which made me think it wasn’t working at first.
