Op-z sequencing Model cycles

Hallo there!
I am an happy owner of model cycles… really a fantastic machine! But I decided to use op-z as a sequencer.
My problem is that on cycles each track has a different midi channel and I would like to use it with only one midi channel that goes on the keyboard of the op z to create rhythmic variations and scales with the master track (who own the op-z knows what I’m talking about )
In fact, it could be done by lowering it by a few octaves in one track but op-z cannot go down that much (on my keystep I did it)
How can i solve? In this way I would also save 6 tracks on the op z and i can dedicate one track only to the model cycles … thanks in advance!
