With ELP, Emerson added the Moog synthesiser behind the C-3 with the keyboard and [[ribbon controller]] stacked on the top of the organ.<ref name=kegear /> The ribbon controller allowed Emerson to vary pitch, volume or timbre of the output from the Moog by moving his finger up and down the length of a touch-sensitive strip. It also could be used as a phallic symbol, and outfitted with a small rocket launcher, it quickly became a feature of the act.<ref name=cateforis /> He continued to divide his keyboard setup into two banks so that he could play between them with his body in view.<ref name=cateforis /> When the ultra-compact Moog [[Minimoog]] first appeared it was placed where needed, such as on top of the grand piano. A [[Hohner]] [[clavinet]] L, with reversed black and white keys, was also part of Emerson's keyboard rig. Although it could be heard on numerous album pieces, according to Emerson, it was only used for one song, "[[Nut Rocker]]" in concert.<ref name=reid />

During the ''Brain Salad Surgery'' tour of 1974, Emerson's keyboard setup included the Hammond C-3 organ, run through multiple [[Leslie speaker]]s driven by HiWatt guitar amplifiers, the Moog 3C modular synthesiser (modified by addition of various modules and an [[oscilloscope]]) with ribbon controller, a [[Steinway & Sons|Steinway]] concert grand piano with a Minimoog synthesiser on top of it, an upright acoustic-electric piano that was used for honky-tonk piano sounds, a Hohner Clavinet and another Minimoog synthesiser. Emerson also used a prototype polyphonic synthesiser produced by Moog, which was the test bed for the Moog [[Polymoog]] polyphonic synthesiser. The original synthesiser setup as envisioned by Moog was called the Constellation, and consisted of three instruments – the polyphonic synthesiser, called the Apollo, a monophonic lead synthesiser called the Lyra, and a bass-pedal synthesiser, called the [[Moog Taurus|Taurus]], but Emerson never used the Taurus.<ref name=kegear />
