Unless we're stopping, then MSD doesn't play the 4th repetition. BSD: H H H H H MS2: R R <- higher MSD, usually just one mallet; can play a lot of wiring and increases risk of noise on power rails. Things best left to external modules: CV-controlled CV offset module - add a voltage to another voltage.
