Any ideas on what is happening in this Dataline video

I love this old but great jam by Dataline. Any ideas what he did to the bass at [25:19] to create such move movement?

The MS 20 is doing a ring mod patch (instant movement between oscillators) pitch and gate data is sent from the A4, and it appears he is using CV to modulate the 2 MS 20 filters. Then a simple octave up arp.

So probably A4 LFOs to MS20 hp/lp filter cutoff.

Many thanks. I might try it on an AK patch using its own LFOs.
