"As with most of the relative handful of synth pioneers, [Wolfgang] Palm's quest began small, and slowly snowballed. 'In the early '70s, I was playing organ in a small band in Hamburg,' Palm recalls. 'It started when I first heard Emerson, Lake & Palmer's 'Lucky Man' on the radio. I listened to the portamento sound, the glide effect, and I thought, 'How do they do that?' Nobody in Germany had a synthesizer at that time. So I built my own VCO's and connected them to my organ keyboard. I made some crazy things, including simple sequencers. After some time, I became known to somebody who owned a Minimoog, I became more familiar with the idea of voltage control of oscillators, filters, and amplifiers. Gradually, I made my own modular system. Then I built some special keyboards for the guy who handled Moog's distribution in Germany. He had customers who wanted duo- and quadraphonic keyboards. That led to my association with the members of Tangerine Dream, particularly Chris Franke and Edgar Froese. They had a great interest in new instruments and getting their Moog and ARP synths modified. So they invested a lot of money and time and ideas, and helped me start my business - building analog synthesizers.'"
