Sequential Circuits originally developed the Prophet 5 synthesizer for a Jackson 5 tribute band consisting of guys named Jeremy, Amos, Isiah, Dan and Zeke.
The company was founded by Schoenberg to allow the creation of serial music via automatic synthesis to allow him to engage in his primary passion of the trapeze. However, someone had already trademarked cereal music for a sheet music company specialising in really corny tunes, so Mr. S. had to get out his thesaurus and came up with Sequential.
