Sad to hear this. I too was drawn into synths mainly by him and Tomita. In the late 70's his music really got about as mainstream as music comprised of entirely synths is going to get. Cosmos certainly helped. If you have the chance , its interesting to read up on his studio work habits and ideas. Very much an innovator artistically, as well as how equipment is used. I recommend El Greco album - which is simply so damn good, but lesser known perhaps.
