In 2001, Machida started to play improvised music by Steelpan with computer program Max/MSP. Machida has been invited to perform for music festivals like ISEA2004, Sónar Tokyo, MaerzMusik, etc. In 2004, Machida founded an experimental music label Amorfon. In 2009, Machida composed soundtracks for Van Cleef & Arpels exhibition. In 2017, Machida released "Music from the SYNTHI 100" with Constantin Papageorgiadis. This album was made by only EMS Synthi 100. Machida also organized "Japan-Macedonia exchange art exhibition" and some workshops for children.
As a visual artist, Machida has produced Photobatik like Photogram technique using photographic paper. Photograms are produced by partial exposure and development of the entire photosensitive surface. Photobatik is "whole exposure and partial development." Machida has expanded his technique to overexposure of the photographic paper followed by only fixing the image, resulting in a pink image.
