Probably an obvious trick, but it was fun to see you actually can turn a Cellz into a limited and somewhat goofy 16-step sequencer by having it "push" itself to the next row at the end of each 4-step sequence -- i.e. set it to the unquantized mode, tune CV2 to full (right) on the south-east cells and zero in every other cell, and finally patch CV2 out to the south-west ↙ input and a clock to the south-east ↘ input.
Unfortunately this doesn't work in chromatic mode, so it's not terribly useful - at best it's a way to modulate a parameter on a loop and have it return after playing around on the touch pad, in a sort of "we have Gliss at home" deal.
