MiniSalt

Hey guys, I'm a new user studying music production at university, currently in the process of doing my dissertation and practical project. While I am aware of several ways to lock the midi being played in either via external keyboard or entered into the piano roll manually to a specific key, I was wondering if there was any way of doing this with the Scripter plugin? The reason for this is that I intend to create a series of scripts using key locking features, for users intending to create electronic dance music genres that can aid to their creativity in some way. For those who are not so good at music theory they may not know what keys are, or even how to chose the right one for the type of track they are working on, research shows that for Dubstep and Trap, F Minor seems to be a very popular key, whereas G# Major is quite unpopular. Obviously this is not always the case however. The other side to this is to not include what keys or specifically in some cases custom keys and notes are being used and that no matter what is played, in theory it should work for that genre. That way they can just load up the script and give it a go. I've seen in a few places that you can transpose from the note being played, up or down in pitch by a certain number of semitones, or even add extra notes in the same way. BUT, is there a way for example to change a black not to the nearest white note, to effectively create a C Major scale lock? And then from this make other scale/key locks like F Minor, where entering an E would instead play the nearest correct note, in this case an F or an E flat? Thanks in advance!
