I bought the EX for the same reason and could not be happier. It took me a minute to figure things out, but you want to be looking at the manual for the Disting mk4. There are several quantizers available. I believe H3 is the one I stuck with before getting addicted to the Chord Engine. Keep in mind, the EX allows you to run two mk4 algorithms at the same time or one of the EX specific “single” algorithms. Hope this helps.
