In a recent interview with Sound On Sound magazine, legendary UK producer 'Martin Rushent' tells the story of a serendipitous moment during the recording of the Human League's number one hit 'Don't You Want Me'.
Martin tells how he was programming a synth line on a Roland 800. During playback the sequencer messed up and played the line half a beat late with the track.
Both Rushent and his assistant Callis loved it. The 'mistake' made it into the final track.
So why not try different quantize values or random sounds when recording, you never know what you might discover!
