Help: Y cabling a JPMM to a Focusrite Solo

I’m sure everybody and their mother have already asked this specific question but I haven’t been able to find a clear answer while sifting through the web. So , what exactly happens when I plug a JPMM to a single input with a Y cable.

Does the piezo suck?
Can I not blend them?
Should I just go with a single cable into stereo?
Is there any combination I am missing that would work the best?
Should I get a Scarlett with 2 inputs instead? How the hell does that even work in DAWs?

There are no music man sellers let alone players in my town so I’m very confused before I actually purchase one.
