Patch script for Roland E-A7

Hi Guys , I currently purchased the E-A7 Arranger made by Roland and i try to use it as a midi
I was looking on the midi device in Cubase and unfortunately there is no installation , or else couldn’t find any on any forums , very frustrating , I understand it is something that can be added , if someone has a template I will be more than grateful to be able to use it , I saw a guide on YouTube on how to create one but that’s is very overwhelming as i got only few hours to create music in a few days
thank you
