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. Sounds and rhythms The CR-78's built-in rhythm sounds were a further development of those available on the earlier Roland Rhythm 33, 55 and 77 machines. The analog percussion voices consist of bass drum, snare drum, rim shot, hi-hat, cymbal, maracas, claves, cowbell, high bongo, low bongo, low conga, tambourine, guiro, and "metallic beat" (an accent that could be overlaid on the hi-hat voice). The CR-78 also has an accent control that increases the loudness of certain steps in a pattern. There are four patterns named "Rock" and two named "Disco". Other patterns are named "Waltz", "Shuffle", "Slow Rock", "Swing", "Foxtrot", "Tango", "Boogie", "Enka", "Bossa Nova", "Samba", "Mambo", "Chacha", "Beguine" and "Rhumba". Each pattern is available in two variations, labeled "A" and "B". It is possible to select more than one rhythm at a time, and also mute drum sounds from a pattern using the balance knob and dedicated cancel buttons. The CR-78 has been used in songs including "In the Air Tonight" by Phil Collins, "I Can't Go for That (No Can Do)" by Daryl Hall & John Oates, "Mad World" by Tears For Fears, and in live performances by Radiohead.
