The KPR-77 was Korg's answer to the Roland TR-606 drum machine. Like the 606, the KPR-77 is an analog machine. Its sounds consist of bass, snare, two toms, open and closed hi-hats, accent and (switchable) cymbal/clap. Each drum sound's level can be individual mixed via the sliders. Holds up to 48 patterns (3 groups of 16) and two songs. A pattern can hold up to 32 steps. Made in Japan.
