The standard tape set offered in the M400 was A. Flute; B. Violins; and C. 'Cello. The cellist was a colorful old fellow named Reginald Kirby who was also a player on a number of Beatles recordings ("Eleanor Rigby" for one). The first five notes of this bank are recordings of an upright bass. It seems that when asked to tune his wonderful 'cello down to cover the lower notes of the 'tron key range, ol' Reggie refused, stating that it would damage his instrument. Eric Robinson then called in a bassist to play these notes, thus the dramatic timbre change. This was another of Robert Fripp's favorite sounds for middle period King Crimson music.
