re: vss list, I think we are about there, I am going with the doubled values after seeing the single value mode flake out in a metro, and we need to add in the constant "mechanical delay" too if/when we have the double pulse sorted out and then look at the fuel parameter. But we are close.
re: piezo, those are amazing and cheap little things. I use 'em as part of diy midi drum pads too. I should give that a shot
