I am a musician and circuit bender and have an SK1 an SK5 and an SK8 which I bought from the US (because I liked the artwork on them) and a very plain SK1 which I bent myself. I have been using a modified SK1 since 1982 (external CV trigger to the chord sequencer) and it appears on a lot of my work with other artists. My brother Adam (Adamski) still owns it.
All sound very different and I use them extensively in most things I work on, Duran Duran, The Dandy Warhols to name but two.
As a musician, I am moving away from purely experimental music (Flashback Generator) and incorporating the sounds into more conventional songs.
