In this video, electronic musician Laurie Anderson, discusses using the H910 Harmonizer. The original H910’s unique pitch change method introduced random ‘glitches’ into the audio and the word ‘glitch’ into the audio engineer’s vocabulary. Not surprisingly, artists found creative ways to use the glitch and, in fact, years later when the H949 was introduced with advanced de-glitching circuitry, some users were disappointed that the glitch was gone. In addition to the glitch, all of the quirkiness of the original H910 has been emulated in the new H910 Harmonizer Plug-in. The system clocks at the heart of the hardware design drifted and wobbled introducing a degree of randomness in the effect not found in later crystal-based, precise digital devices. This was evident in the way that the display would flicker between pitch ratio readings. The combination of glitch, randomness and analog signal path, especially when the feedback control was turned up, added an ‘organic’ feel to the sound and that feeling comes through in the plug-in.
