Vortex Sound Research

I have a keystep with a volca keys and everytime I hit play on the keystep it starts the sequencer on my keys. I read that I needed to change the transport mode in the midi control center from “MIDI CC” to “MMC” but nothing seems to have changed. Anyone have any luck figuring this one out? I heard another solution is some kind of box that filters out certain kinds of messages. Any help is greatly appreciated! ?
