A big influence on Stevie Wonder: http://www.youtube.com/watch?v=wuaSzFf7yq0

"Synthesizers are so pervasive an element in popular music of all types today that it's easy to forget what a novelty they were only 25 years ago. TONTO is an acronym for "The Original New Timbral Orchestra": the world's first (and still the largest) multitimbral polyphonic analog synthesizer, designed and constructed by Malcolm Cecil. Its warm, rich timbres were particularly noteworthy and still cannot be recreated by the current breed of MIDI digital synthesizers and samplers.

TONTO began life as a series III Moog modular synthesizer. A second Moog III was added in 1971 and TONTO continued to expand with various custom built as well as standard modules (somewhat modified) from many synthesizer manufacturers including Serge with Moog-like panels, Oberheim, Arp 2500/2600, EMS, Roland, Yamaha, etc. In the mid 1990's TONTO resided at Mutato Muzika studios the headquarters of Mark Mothersbaugh and Devo which is the basis of the widespread rumour that Mark had aquired TONTO. Actually it has been in the private ownership of Malcolm Cecil since 1975 when Robert left the Head Band to persue his career as a producer. Currently TONTO is alive and well and resides in its own studio in upstate New York close to Woodstock. "
