The Roland MC-8 MicroComposer by the Roland Corporation was introduced in early 1977 at a list price of US$4,795 (¥1,200,000 JPY). It was one of the earliest stand-alone microprocessor-driven CV/Gate music sequencers,[1][2] following EMS Sequencer 256 in 1971[3] and New England Digital's ABLE computer (microprocessor) in 1975.[4] Roland called the MC-8 a "computer music composer" and it was considered revolutionary at the time, introducing features such as a keypad to enter note information and 16 kilobytes of random access memory which allowed a maximum sequence length of 5200 notes, a huge step forward from the 8-16 step sequencers at the time.[1][5] It also allowed the user to allocate multiple pitch CVs to a single Gate channel, creating polyphonic parts within the overall sequence. Due to the high price, only 200 units were sold worldwide, but it represented a huge leap forward in music technology.[1][6]
