In this video, Roy Hendrickson (Frank Sinatra, Miles Davis, Ariana Grande) compares the original H910 hardware unit to the H910 Harmonizer® plug-in. The H910 Harmonizer® was the world’s first digital effects processor. With its unique combinations of pitch shifting, modulation, and delay, the H910 has made its way onto countless ground-breaking work by artists from AC/DC to David Bowie to Frank Zappa. Simply put, nothing sounds quite like it. The original H910 was a 100% software-free analog and digital processor that predated the earliest practical ADC or DSP chips by several years. It used simple digital logic gates and some of the earliest RAM memory chips but was, in large measure, an analog beast. A custom analog-to-digital converter, compounding, filtering and analog feedback combined to give the unit a distinctive sound which this plug-in faithfully re-creates.
