The Roland VP-330 is a paraphonic ten-band vocoder and string machine manufactured by Roland Corporation from 1979 to 1980. While there are several string machines and vocoders, a single device combining the two is rare, despite the advantage of paraphonic vocoding, and the VP-330's synthetic choir sounds are unique. Despite the VP-330's electronic string and choir sounds being less realistic than those of the tape-based Mellotron, touring musicians used it as a lighter and more robust alternative.
