"The major drawback of the RMI was its total lack of touch sensitivity. I found this very restricting, especially since any bum-notes are played at full volume, no matter how lightly you brush against them. The other limitation was the width of the keyboard itself -- 68 notes, as opposed to the 88 on a real piano. I remember one incident at Drury Lane when I was playing the introduction to 'Firth of Fifth.' Because of the RMI's 68-note limitation I had to transpose one part of the introduction down an octave to fit it in. Well, there I was, everything was going really well, and I just got carried away. I forgot that I wasn't sitting at a piano, and ran out of notes. I stopped. Peter, Mike and Steve just looked at me in amazement."
