Another synth demo, this time with the Sequential Circuits Prophet~600 buddied up with its siblings. This synth was the very first instrument released with midi (with Dave Smith of Sequential being the "father of midi"). He was later awarded a Grammy for its invention along with Ikutaro Kakehashi of Roland. It was famously hooked up to a Roland Jupiter-6 at the Winter NAMM of 1983 to demonstrate that a universal protocol had been achieved. The Prophet~600 was the third of this iconic series to be released after the Prophet~5 (1978) and Prophet~10 (1980). With their eye on affordable poly synths such as the Kory Polysix and Roland Juno-60, Sequential looked to create a cutdown version of their earlier Prophets and the 600 was the result. Around 6,000 of them were made between 1983 - 1985.
