Make 2 clones of the instrument, then detune +/- each clone.

I have a better idea. How about you try making music where you split you high pitched instruments with you low ones?

I already did that with earlier/primitive versions of OS circa 2015. Be grateful to the devs that OS now allows you to clone instruments, among other improvements over the years. OS is free and they don't get paid working on it.
