Prophet-5
The Prophet-5 is an analog synthesizer manufactured by the American company Sequential. It was designed by Dave Smith and John Bowen in 1977. It was the first polyphonic synthesizer with fully programmable memory.
Before the Prophet-5, synthesizers required users to adjust controls to change sounds, with no guarantee of exactly recreating a sound. Sequential used microprocessors to allow users to recall sounds instantly rather than having to recreate them manually. The Prophet-5 facilitated a move from synthesizers creating unpredictable sounds to producing "a standard package of familiar sounds".
The Prophet-5 became a market leader and was widely used in popular music and film soundtracks. In 1981, Sequential released a 10-voice, double-keyboard version, the Prophet-10. Sequential introduced new versions in 2020, and it has been emulated in software synthesizers and hardware. Sequential also released several further Prophet synthesizers, such as the Prophet '08.
The Prophet-5 was created in 1977 by the American engineers Dave Smith and John Bowen at Sequential Circuits. At the time, Smith had a full-time job working with microprocessors, a new technology. Smith conceived the idea of combining them with synthesizer chips to create a programmable synthesizer; this would allow users to save sounds to memory, rather than having to recreate them manually. He did not pursue the idea, assuming Moog or ARP would design the instrument first. When no instrument emerged, in early 1977, Smith quit his job to work full-time on the idea.
Initially, Smith and Bowen developed the Prophet-10, a synthesizer with ten voices of polyphony. However, it was unstable and quickly overheated, creating tuning problems. Smith and Bowen removed half the electronics, reducing the voices to five and creating the Prophet-5. Smith demonstrated the Prophet-5 at the NAMM Convention in January 1978 and shipped the first models later that year.
Three versions were built between 1978 and 1984. The first, Revision 1, was hand-assembled and produced quickly to generate initial revenue; only 182 were made. Revision 2 was mass-produced in quantities over 1,000; this model was more robust, added cassette patch storage, and replaced the koa wood casing with walnut. Revision 3 replaced the Solid State Music (SSM) chipset with Curtis (CEM) chips, necessitating a major redesign. According to Sound on Sound, Revision 3 "remained impressive and pleasant to play, but was slightly cold and featureless by comparison to earlier models". Almost 6,000 Revision 3 models were produced.
In 1981, Sequential Circuits released the Prophet-10, featuring 10 voices, 20 oscillators, and a double manual keyboard. Like the Prophet-5 Revision 3, it uses CEM chips. The first Prophet-10s used an Exatron Stringy Floppy drive for saving patches and storing sequencer data. Sequential later moved to a Braemar tape drive, which was more reliable and could store about four times as many sequencer events.
In 2020, Sequential released a new version, the Prophet-5 Rev4, with additional memory and features. They also released a new version of the Prophet-10, with the same external design as the Prophet-5.
