Microtonal notes

i have a unique feature request, if its not already possible in the program,
im using gp10 with gk-3 pickup and cubase,

i want to play on my guitar arabic maqams

which some require nots that are quarter tone above or below the normal notes

i thought it would be nice if for example it would be possible to make for a way for example: on string 2, when note E is detected , make it quarter tone higher.
expanded super option: make it raise it only when monophonic nots plays and not chords

well i know , this is far from the purpose of midi guitar ,but its a real unique one that can make normal guitar play a new world of scales

if you know how to do it already → please tell me
thank you

What do you mean by “string 2,” the B string? If LUA scripting works (which I’m not sure it does), you could write a script that raises the E4 on the B string by a quarter note when no other notes are played simultaneously. I strongly suspect you’re using a VST plugin in Cubase. Which instrument are you using? Kontakt, for example, offers a built-in LUA scripting option that you could use to do the same thing as described above.
