Korg KPR-77 (1983)
The KPR-77 was Korg's answer to a price problem. In the early 1980s, a fully-featured programmable drum machine cost over $1,000. The KPR-77 was a programmable rhythm unit priced to undercut the competition by a wide margin. High Fidelity (March 1983, p.69) listed it at a suggested price of $569. That is roughly half the cost of a Roland TR-808 and a fraction of the Linn Drum's $2,995.
That same High Fidelity comparison chart shows where the KPR-77 sat in the market. It offered a snare, bass drum, two tom-toms, and a hi-hat. That is a noticeably leaner set of sounds than the TR-808 or Oberheim DMX has, but far more than the bare-bones Roland DR-55.
Period advertising from Modern Recording (February 1983, p.37) made the same pitch: full-featured programmability without the four-figure price tag, built on microcomputer technology borrowed from Korg's then-market-leading keyboards. The implication was that the KPR-77 gave you sequencing and programming that used to be reserved for expensive studio gear, in a package aimed at working musicians on a budget.
Beyond that positioning, the documented record is thin. The KPR-77 was one of several compact, affordable drum machines that appeared in the early 1980s as programmable rhythm units moved from high-end studios into the project-studio and home market. It does not appear to have reached the lasting cult status of its Roland contemporaries, and detailed technical documentation is scarce.
