I am trying to recreate a chiptune song and for the bass i just need to be able to get just one note lower, so please add another ocatave to the lower end of the piano roll scale.

you could always just transpose the song up one and your problem would be solved.

It just doesn't sound the same as the original then. It is no solution.
