Above: Sequential Circuits Prophet-5, Remote Prophet, and Poly Sequencer c.1982. Below: period adverts for the Pro-One and Prophet 5. We have a slightly later Sequential Six-Trak at Gold Coast Recorders; it’s sorta SC’s Juno-106, and it’s one of the best deals in vintage analog synths – if you don’t mind the clumsy digital interface. I’ve never used a Prophet-5; they are extremely expensive these days. Anyone?
