LEO and Roland TR-808
Lewis is most famous for having created an early integrated sound controller for analog synthesizers, which he named Live Electronic Orchestra (LEO), 10 years prior to MIDI. Lewis designed LEO in 1974 and completed it in 1977 by linking various synthesizers to work together in live performance, limited at the time to mostly studio production. As of 2018, LEO is housed in NAMM's Museum of Making Music located in Carlsbad, California.
The various instruments of LEO include
- Hammond Concorde
- (4) Oberheim Expander Module (SEM)
- ARP Pro-soloist
- (2) ARP 2600's
- Roland Jupiter 4
- Roland Promars
- Roland Space Echo
- Roland Digital Chorus
- Roland VP-330 vocoder
- Roland TR-808
- Hammond X-66 pedestal
- Pascetta Polyphonic Keyboard
- Roland 8 channel mixer
For over 10 years, Lewis collaborated with Ikutaro Kakehashi on rhythm units including the FR-7L, CR-68, CR-78 and the Roland TR-808, a drum machine that allowed musicians to program and create their own drum beats. He also contributed to the rise in popularity of other synthesizers such as the Yamaha DX7.
