I've been doing this, since the early nineteen eighties, as a solo performer who sometimes engages the collaboration of other respected players/creators.
I used to play live, but now, I primarily work in studio productions with others as well as myself.
Klaus Schultze, Tangerine Dream, Pink Floyd, King Crimson, The Stranglers, Ray Lynch, Emereeson, Lake and Palmer, Genesis (early period), Gentle Giant, Peter Hammil, Van Der Graaf Generator, Popol Vuh, Kraftwerk, Kettle, Subotnik, Hugh Lecaine (inventor of the Electronic Sackbut- 1940'S) AND and a slew of others!
