since you already have marbles, try creating some short looping sequences with deja vu and use that to control params on the BS. If you use the same clock for both you can get a lot of variation in your sequences. just by way of example, i currently use a Marbles and an XAOC Moskwa II (with expander). I send the Moskwa clock out to marbles, and then the X outs back to Moskwa to manipulate transposition, random amount, overall pitch range, etc.
