Here are accent output voltages for the available velocity configuration options.
from the manual...
There are currently four velocity map options.
Option 1 has a higher minimum voltage, rising linearly to the maximum voltage output.
Option 2 has a lower minimum voltage rising to a lower maximum.
Option 3 is similar to option 1, with a slightly reduced maximum voltage, to suit the lower possible voltage range with a Euro-rack 12V supply.
