Time-Lag Accumulator

leave a comment »

For a while, I’ve been meaning to recreate the ‘Time Lag Accumulator’ used by Brian Eno and Robert Fripp on their early ambient music.  The setup was simple – two tape decks with a single loop of tape, guitar feeding in one.  The output of the second deck was fed back and mixed with more guitar.  A very simple delay, 3-5 seconds in length.

This was pretty easy to do using Ableton Live and 10 ‘Simple Delay’ plugins, although this is cumbersome:

I included to inputs to the loop – a microphone feed (from guitar, mic, whatever) and a MIDI instrument channel.  The MIDI instrument is fun to play with, but I’d love to connect the Rhodes once I’ve finished cleaning it up…
