Skip Step Sequencer Logic

Hi all,

I'm attempting to replicate the Make Noise Rene sequencer in Max and I'm struggling with a logic problem. The Rene takes multiple inputs, but the main inputs revolve around an X and a Y trigger to move the sequencer along in either the X or Y... you can turn off steps by touching any of the 4x4 knobs and it 'skips' the sequence.

To simplify, if i have 4 toggles and a bang, let's say X X 0 X where X is a 1 on toggle and 0 is a 0 on toggle; each time i bang i want to move my count forward ie: 1, 2, 4, 1, 2 ,4 along the 4 step X direction... and then output what beat i am on (1,2,3 or 4). How can i create a logic to track this variable to track this change? I could expand this to the x then y (then z!) if i could figure this out.. thank you!
