RD-8 sync to Keystep

first time posting on Reddit, forgive the cluelessness. I'm trying to get my RD-8 be the master clock to the Arturia Keystep, which controls the KARP2600m. Something is happening but having trouble getting the PPQ to be what I want, and also the drum machine playing in 4/4 seems to be sending a signal every 6 and 1/16 beats!
