//At the moment the currentl alg. belows won't allow you to transpose a scale
//if ANY note will be transposed to above 119. Also, when transposing the note
//you select will be the lowest note. However in the old software it was possible
//to transpose notational arrangements so that the bottom set of notes would all
//equal 0 or the top sets would all equal 119, meaning you could have more choice
//over where the arrangment starts and ends. Do we want that here? If so, the below
//code will need to be changed to how it was before (most of it has just been
//commented out.
//Get the 'root note'.
//Should the root note be the note of the first select pad (selectedPads[0]).
//Or should it be the lowest note?
//Below is the code to find the lowest note.
