Bit of a long shot but I'm struggling with this one

I Bought a D-Thing+ Eurorack module to control my Moog DFAM. Works a treat. Was hoping to be able to control the D-Thing+ from Reason. I'm connecting from Reason via an Expert Sleepers ES-10. From Reason I'm using a RoboticBean CV to Audio RE to send gates/CV from (for example) a Matrix, out via the ES-10 and into the D-Thing+. This works fine for triggering. So, I can sync from Reason's transport - hit play in Reason, the DFAM plays long at the same tempo. So far, so good. But I'm struggling with the triggering of individual steps of the DFAM. I'm basically trying to set up in Reason what the guy in the video below is doing from a Korg Sequener. Not having much luck so far and struggling to work this one out. Best I've got is some more or less random triggering of DFAM steps from a Matrix. But it wasn't very 'controlled'
