I have been watching pitch shifter technology for the last four decades, waiting for something that musically transposes my sound many octaves without a delay that makes it unplayable, and without shifting artifacts that make it sound unnatural. That pitch shifter never came, even the best studio units are unusable as a real world musical instrument. So, I invented the Chromavoder. It is a revelation. Not just a pitch shifter, it is a harmony instrument in itself, using sound that comes from the player. It is demanding on a wind or fretless instrument player, requiring precise intonation. Playing it has sharpened my skills. It is a great tool for musical performance and for music education.
