This script allows you to convert a specific MIDI note into another one, this is really useful if you want to change the key switches of an instrument, but the instrument can’t do it by itself. You can want this in order to have a better control of your key switches, because sometimes is really difficult notice which one is a real note or a key switch, in some cases, developers set key switches near to real notes, and this can affect your workflow a lot, especially if you don’t use a MIDI controller.
