Using a Roland JV1010 in Cubase. Please help!

How do I use the 1010 “on its own”? I need a MIDI signal in order for it to output anything.

What I’ve been doing is recording a MIDI signal into an instrument track with my MIDI controller, then closing out Cubase and re-initializing the MIDI with JV1010 and changing the output of the recorded MIDI track to be that of the JV1010. This does not produce any sort of output.

If I were to use the microkorg as a MIDI controller WHILE using the JV1010, how would I set that up? MIDI OUT of microkorg to MIDI IN of JV1010. MIDI THRU of JV1010 to MIDI OUT of interface, MIDI OUT of JV1010 to MIDI IN of interface. Does that sound right?
