The transpose feature is there for a reason to use, especially if your a singer player or have a guest singer or duo etc,...It is essential for singers I always use it..great feature for modulations in live play also, only if its a one button push +/- I remember some arrangers needed two pushes +/- and that not good when you have to make a split second modulation change in a song live on stage, (which usually isn't on the charts for readers)...alternately a pedal can be used but, in no way is it faster or more accurate then a finger push imo.
