Welcome 
If you are looking to use the 40h as 64 independent triggers, check out the 64 fingers app. This is designed for this purpose. This may or may not be available on monome.org as it is an older app.
Have you downloaded max runtime, and tried connecting the 40h? Check out https://monome.org/docs/ for installing the relevant software and test.
Perhaps someone more knowledge than me could confirm if the 40h requires monomeserial?
