 The Mellotron became more popular after the Beatles used it on several tracks. It was subsequently adopted by the Moody Blues, Genesis and King Crimson, and became a notable instrument in progressive rock. Later models such as the M400, the best selling model, dispensed with the accompaniments and some sound selection controls in order to be used by touring musicians. The instrument became less popular in the 1980s due to the introduction of polyphonic synthesizers and samplers, despite a number of high profile uses from Orchestral Manoeuvres in the Dark and XTC.
