Banton was born into a musical family, where his father played the piano and his mother regularly sang along to music on the radio. Two of his uncles were church organists. He first started playing the piano at the age of 4, beginning formal piano lessons at 7. He was equally influenced by the family classical record collection and by music heard on Radio Luxembourg. In his teens he studied classical piano & organ whilst attending Silcoates School in Yorkshire under Dr Percy G. Saunders, organist at Wakefield Cathedral, however he continued to enjoy both rock 'n' roll and classical music. After leaving school he trained as a television engineer with the BBC in Evesham, and subsequently in London, before joining Van der Graaf Generator in May 1968 when the group moved from Manchester to London. In performance with this group he played Farfisa and Hammond organs, adding a wide range of effects including phasing, tape echo, distortion and overdrive. From 1970 he took over the bass-player role within the group, using the organ foot pedals. He also played bass guitar on recordings. He modified his Hammond E112 organ to allow separate amplification, with different effects, of the output from the two keyboards and pedalboard, and he also devised a stereo reverb unit. In 1975 he began building a custom organ based on a Hammond but with added electronic oscillators to approximate a full pipe organ sound. Electronics, particularly the development of organs, have been a parallel interest since his early teens. Banton changed career at the end of 1976 and left Van der Graaf Generator to work on the development, design and installation of electronic church organs for the Makin Organs company in Oldham, Lancashire, where he became Technical Director. In 1992 he set up his own company The Organ Workshop at Lymm in Cheshire, and latterly in Evesham, Worcestershire. His organs use digitally generated waveforms to emulate the sound of pipe organ stops, and a recent speciality is combining digital organ stops within conventional wind-driven pipe organs, to create a larger hybrid instrument. His company have installed organs of all sizes both in the UK and abroad. Commencing in 2017, Banton has been developing a PC software project - HB3 - which further researches the real-time production of pipe-organ sounds by digital means. Since the reunion of Van der Graaf Generator in 2005 he has regularly contributed to concerts and recordings with former members, which continues as a trio with Peter Hammill and Guy Evans.
