    The roman player listens to an incoming note signal and then only really pays attention to the velocity, duration, and scale data.
    The actual note played depends on a symbol off the scale, whether a note or a chord.

    As such, a ScalePlayer makes the most sense to have higher up in the chain.

    r = RomanPlayer(symbols=["I 2 3 4 IV 2 3 4 iii"])
