yes he is a FM freak, I thing he has never used an analogue synth, I remember when I was a rookie and tried to imitate his FM leads with my top notch analogues,until I realised it was impossible an discovered later fm ,I couldn´t belivev in the analogue hyoe era that those sounds were coming from those cheap yamaha synths..

I learn several yeras ago that he was using too a Korg 707,another fm synth,regis got an yamaha tg 33 too.
