Amplifier velocity tracking, represents how much the amplitude changes with incoming note velocity.
Volume changes with incoming velocity in a concave shape according to the following expression:
Amplitude(dB) = 20 log (127^2 / Velocity^2)
The amp_velcurve_N opcodes allow overriding the default velocity curve, and are useful for making more complex curves than amp_veltrack allows.
Allowed values are from -100 (which would make velocity 127 notes silent, and low-velocity notes loud) to 100, but for most practical purposes this paramter is generally set to either 0 or 100.
