The Echo Nest Remix API [1] comes with a demo, enToMIDI [2] by Brian Whitman [3], which attempts to transcribe any audio file using only Remix's audio analysis data, and spits out a MIDI file. The purpose of the EN audio analysis data is to provide a summary of the music, not to do the source separation necessary for an accurate transcription. This means the resulting MIDI file usually doesn't sound much like the input.

MIDI Digester is a very small script [4] that runs audio through enToMIDI, plays back the resulting MIDI using Quicktime and its built in piano synthesizer, records the audio with sox [5], then repeats the process as many times as you want. Each repetition strips away more of the original musical material and accumulates the sound of enToMIDI.

This demo "digests" a 7.66 second excerpt of the traditional bluegrass tune "The Groundhog" played by the same Quicktime piano synthesizer.

Apart

/ n/// n (nacht und nebel)

_headphones are highly recommended_

for orkest de ereprijs

a sustained chord from Wagner’s Das Rheingold, drum fills that hint at no wave, guitar and bass riffs that are interrupted by volume pedal changes, a Nazi Proclamation, tabloid article and operatic text:

the deconstruction of different muses to their bare roots, interrupted and juxtaposed between one another, original meaning of content has been deconstructed and built anew. they influence, collide, and react with one another. their original identities have been changed from the outside. they are amplified, transposed and cut until they have become only ghosts of their original identity, their original context, their original meaning.

/ n/// n {or wagner no wave tabloid magazine music} (2013)

Nothing repeated
never never never
 
The title is a poem by Gregory Abels. 

I showed this piece to Mike Perdue and he wrote this:

This is a sick twisted lava lamp.
Fava beans in a swamp.
Stick stirring     damn

Nothing Repeated Never Never Never
