So, if you had just announced a new product dedicated to doing a particular function, would you then go implement that on another product that was never intended to have that function? Doesn't make sense business wise to implement polyphonic sequencing even with reduced polyphony when a product is being released dedicated to that particular function.
You probably disagree, but I'm doubtful you are going to convince them they would benefit from adding poly-sequencing to the BSP.
