ELP's record deal provided funds for Emerson to buy his own [[Moog modular synthesiser]] from the US, which was a preset model that had fewer leads and punch cards to call up certain patches.<ref name=OTT84/> He used the patch that Vickers provided, which contained six distinctive Moog sounds and became the foundation of ELP's sound.<ref name="Analog Days" /> It was a temperamental device, with the oscillators often going out of tune with temperature change.<ref name="Analog Days" /> Emerson was the first artist to tour with a Moog synthesiser. His "Monster Moog", built from numerous modules, weighed {{convert|550|lbs|kg}}, stood {{convert|10|ft|m|0}} tall and took four roadies to move. Even with its unpredictability, it became an indispensable component of not only ELP's concerts, but also Emerson's own.<ref>{{citation|last=Bernstein|first=David|newspaper=The New York Times|title=A Comeback for Another Classic Rocker: The Moog Synthesizer|date=29 September 2004}} "Mr. Emerson's towering, 10-foot-tall, 550-pound ''Monster Moog,'' as he called it, was an indispensable part of the group's concerts, even though it was often unreliable and difficult to play."</ref> His use of the Moog was so critical to the development of new Moog models that he was given prototypes, such as the Constellation, which he took on one tour,<ref name="Analog Days" /> and the Apollo, which had its début on "[[And did those feet in ancient time|Jerusalem]]" on ''[[Brain Salad Surgery]]'' (1973).<ref>{{cite web |url=http://ultimateclassicrock.com/elp-brain-salad-surgery/ |title=40 Years Ago: Emerson, Lake & Palmer Release 'Brain Salad Surgery'|last1=DeRiso |first1=Nick |date=19 November 2013 |website=ultimateclassicrock.com |publisher=[[Townsquare Media|Ultimate Classic Rock]] |access-date=13 March 2016 |url-status=live |archive-url=https://web.archive.org/web/20150123080410/http://ultimateclassicrock.com/elp-brain-salad-surgery |archive-date=23 January 2015 }}</ref> As synthesiser technology evolved, Emerson went on to use a variety of other synthesisers, including the [[Minimoog]], [[Yamaha GX-1]], and several models by [[Korg]].
