I have used synthesizers since the 1970s. I have owned very few of them, but I have been fortunate enough to borrow gear - lots of gear! - from others, and have over the years used many famous synthesizers. I started with a TEAC 4-track reel-to-reel tape recorder, a multimoog and the Yamaha DX7II early on, and over the last years I have bought some more gear and instruments. And I have finally been able to build my own large, modular analog synthesizer together with Erik Stormer - the WintherStormer modular.
