If the velocity is a^x, with a a number like 1.1 and v a number between 0 and 255, I would agree. However, what I’ve seen is that 2 is twice as loud as 1 and 25

If the velocity is a^x, with a a number like 1.1 and v a number between 0 and 255, I would agree. However, what I’ve seen is that 2 is twice as loud as 1 and 256 twice as loud as 128. That means soft passages become discretized and uneven.
