i think the easiest way would be to create your own key, by utilizing the same feature as utility skills. example, say i want to flat my E, click on the arrow on top of the note and choose the note you want to play. so if i want to play in the key of C minor, i would change first note to C second to D , etc. could be the easier way to do it, since you wouldnt need that much of a UI change and everyone could play in the key they wanted. instead of changing octaves, let it be another key you customize. so, first set would be, for the sake of illustration, key of C minor, second would be…B flat major…that would be my idea, i think it could work, what do you guys think?
