Can't figure out external MIDI instruments at all!

I recently purchased a guitar/bass, Moog Sub Phatty 25, and a Korg Minilogue XD. I’m dying to try them out but I just can’t figure out how to get them to work in Cubase. My interface is a Focusrite Scarlett 2i4. I’ve downloaded the Scarlett drivers and set it as my default sound device. I tried following some guides on adding external instruments with the MIDI device manager but nothing seems to work.

I’ve been able to get an input signal on key press, so I think Cubase is receiving the MIDI signal. I was using a quarter inch cable from the audio out port on the synth, into the front port of the Scarlett. I’m just not getting any sound. I apologize for my complete lack of knowledge here this is all new to me. Any help would be greatly appreciated!

Hi and welcome,

Here you can see the basic connection. Just be aware Devices menu has changed to Studio and VST Connections has changed to Audio Connections.

And here you can find “How to Utilize External MIDI Instruments in Cubase” video.
