"The Roland CR-78 CompuRhythm, a classic analog Rhythm Machine and the first to use a microprocessor to allow programming of own patterns. It has 34 built in preset rhythm patterns and offers 14 drum tones. The CR-78 allows to combine 2 rhythms. Also you can cancel bassdrum, snare, cymbal, cowbell / claves. A little mixer allows adding guiro, cymbal and metal beat. With 11 variation effects and the ability to adjust tempo, accents and fade in/outs, the CR-78 is still capable of producing a wide variety of rhythms.

The Roland WS-1 programmer was designed to program the CR-78, but you can also use a Korg MS-20 or even a simple footswitch. You can program 2 bar patterns one voice at a time and up to 4 voices can be simultaneously played. Each of the four voices can be independently muted from the front-panel. Patterns can also be set to fade-in/out. The CR-78 has external trigger using 24ppq V-Trig clock pulse.

You don’t need a TS-1 write switch to program the CR-78. Any CV converter will do as long as it has a clock out. Instructions for programming are found here: http://www.submodern.com/slowburn/?p=608 (he uses a Korg ER-1 but its much easier using a computer)."
