Tony,
the mind behind Steely Dan is a guy called Donald Fagen, who later left the group and pursued his own career as a solist. His album "The night fly" is still considered a reference to test an hi-fi system; he is a real maniac about sound quality; I once read an interview where he said that he hated synthesizers (all of them) because they are never in pitch, meaning that even when a sound is in pitch in one octave, it goes out of pitch in the other octaves (lower or higher). That's why in his record you can usually hear only acoustic instruments or the Rhodes piano, where you have to tune each note individually.
