Do you know how to get this type of lead sound?

Can you give me some guidance on how to get the kind of lead sound heard in Oxia - Domino?:

Do you think it's layers of different single note sequences / chord stabs / arp's etc?

Do you have any idea what the midi notes look like and whether it's multiple patterns playing etc?
