YLE Elävä Arkisto features some videoclips of DIMI, perhaps one of the first digital synthesizers in the world, which was designed in 1970 by Finnish electronic music pioneer Erkki Kurenniemi. Also part of the DIMI series was the "video organ" DIMI-O, guided with a video camera, which converted the real-time movements of performers into sounds and music. In an English-language demonstration film dancer Riitta Vainio shows off the possibilities of DIMI-O in 1971. DIMI-S (a.k.a. The Sexophone) registered through electrodes attached to performer's skin any emotional changes in him or her.
