Script – Key Range Transpose
This script allows you to transpose a certain range of notes into another one, moving them some semitones up or down. It is really useful if you want to transpose an instrument to another octave, or If you want to transpose a certain range of key switches.
It has a menu in which you can select how many ranges you want (you can select from 0 to 6).
Then, you can define the ranges, and the semitones amount in order to transpose them.
