Lord transplanted the internals of an RMI into a Hammond organ and allowed it to be triggered from the Hammond's manuals. Banks later said he used the RMI as it was the best possible onstage alternative to a piano at the time, but disliked the lack of touch sensitivity and fewer notes than a grand piano. Owing to a lack of polyphonic synthesizers, he ran the RMI through effects pedals in order to create new sounds. The RMI was used for live renditions of songs that had a piano on the studio version, such as "Firth of Fifth" and "The Lamb Lies Down on Broadway". He eventually replaced the RMI with a Yamaha CP70.
