Computer controlled feedback and ensemble
Feedback is a musical gift that keeps on giving: turn up the microphone and let acoustics do the rest. I fell in love with feedback as a teenager seeking inexpensive routes to electronic music in a time before laptops and affordable synthesizers, and it returns to my repertoire with the periodicity of a comet (see Roll, Pitch and Yaw on Saturday’s program). The half-dozen microphones in Long Fetch switch from speaker to speaker as soon as they start to feed back, producing pitches that vary with the distance between each mike and its current speaker. These musical patterns respond to sounds in the room, both ambient and performed.
