Strumming from Sequences via Komplusion

Question came up "How can you add a strum function to Robotic bean sequences that would strum the chord that you choose? Say for instance, you have a Sequences with 1/4 resolution, 4 different chords you only want to affect the second and fourth chord, leaving only the 1st and third chords unaffected, but yet still play." this is the solution that I came up with.
