CompuRhythm CR-78 is a drum machine launched in 1978. Although primitive by later standards, the CR-78 represented an important advance in drum machine technology at the time, in particular by allowing users to program and store their own drum patterns.

The CR-78's front panel allows the user to customize the preset rhythms by altering the volume balance between bass and treble sounds, canceling some sounds altogether, and adding "metallic beat" (three filtered square waves that create a distinctive chime timbre). Many of the preset rhythms have a memorable character, and the ability to manipulate them further made the CR-78 a versatile instrument. No digital control of tempo is provided on the front panel, with only an analog knob for tempo control. However, the CR-78 accepts an external V-trig clock, allowing a

. Roland also produced a simpler drum machine, the CompuRhythm CR-68. This was essentially the same as the CR-78, but without programmable patterns or the ability to fade drum sounds in and out. A large cabinet version, the CompuRhythm CR-800, with capabilities between the CR-68 and CR-78, was also produced. At the same time Roland also sold the TR-66, a smaller unit that offered fewer preset rhythms and no programmability.
