Jon Johnson Report post Posted April 13, 2017 The Roland CR-78 CompuRhythm is considered a classic analog rhythm machine as the first of its kind to use integrated circuits. An important development in the history of drum machines. This allowed for the introduction of a Programmer section, which provided 4 programmable memory locations for pattern storage. Now users could program and store their own drum patterns, as well as adjust tempo, accents, and fade ins and outs. Individual mute controls for each of the four voices were featured on the front panel, allowing the user to create breakdowns. View full drum machine Share this post Link to post Share on other sites
