You know your way with scales...I'm unfortunately not. OK, so I can make another midi switch but what do I have to do or to change this setting to get a major third in D:
https://ibb.co/3m9GrWy which adjustment are we talking about?
BTW, as you have noticed, this solo-part at the end is pretty fast... There must be absolutely no latency in sound going from switch #3 to switch #4...if it is already possible to achieve this during the fast part for only one note...!
