Back, and Feed

"Back, and Feed" is a project created entirely using Max. In the first section of the piece four samples of an A440 tuning fork are recorded live (picking up various degrees of accidental noise in the room), then played back at varying pitches on a keyboard. The keyboard plays one of the four samples at the pitch selected. For the end of the first and entire second section of the piece, feedback is created using a microphone pointed directly at a speaker, and the input channel is filtered by a tuned band-pass filter and a resonant delay. Up to three feedback lines are used simultaneously, and the lines are tuned by selecting a pitch on the keyboard. The third section uses a long (30 second) delay, while the sound is feed back via an outboard mixer with an eq in the feedback loop. A Moog mf-104m is used throughout. The visuals are created by manipulating videos in Jitter, which is controlled by an APC 40 midi controller.
