Creating trance and techno music on piano

Me and my friend we're thinking about doing song arrangements together of the songs from a game called blinx since no one else has. Like this music here: BLinx: Everwinter I've seen a few people who do things kind of like that on an acoustic piano but the problem is that I don't know how to create that fast repetitious accompaniment Riff in the background and we will need to. I'm sure it's based off of a chord but I'm not sure how you create that pattern from the chord.

Bass octaves and major 7's and inversions in a rythmic pattern.

Just a thought.

If you listen closely it's the same pattern play'd over and over again on different pitches. Make a theme, a easy repetive one, then make a basspattern that's even less complicated. Merge them together and run the theme up and down the piano. Lets pretend the theme is C-D-F-A-G, you can play this starting at the middle C, then you probably wanna jump to the C above or the next, to make depth you wanna add some notes in there so you dont jump 2 octaves right away, but climb your way up to octaves again. There you can also make a patter, B-A-C-B-D-C-E-D, somethign like that.

Bass = easy basspattern or and arp
Theme = A short melody
Merger = a pattern climbing or falling down octaves in between the themes.

That's the most basic trance/techno. It's usually very repetive.
