The band found it difficult to use electronic instruments and techniques collaboratively; according to Yorke, "We had to develop ways of going off into corners and build things on whatever sequencer, synthesiser or piece of machinery we would bring to the equation and then integrate that into the way we would normally work." They experimented with electronic instruments including modular synthesisers and the ondes Martenot, an early electronic instrument similar to a theremin, and used software such as Pro Tools and Cubase to edit and manipulate their recordings.
