Oxia - Sun Step - Getting that bass sound and correct midi pattern

Hi all,

I was wondering if someone could help me. I would like to know how to create the bass sound and also which midi/pattern notes to use when creating a similar bass sound to that of the one in Oxia’s Sun Step track. I can create most of other bass sounds apart from this. I have spent hours trying to re-create it but no luck as yet!! I have noticed there are many tracks using this particular style at the moment.Here is a Youtube link of the track -

My preference would be to use the Sylenth as its the one synth I am familiar with.

Can anyone advise me please?

Thanks in advance for your help
