The Air Traffic Controller mixes a Rainger FX optimum distortion circuit with a white noise 'hiss' generator, and sends the sound through a low pass filter. The cut-off frequency of the filter is controlled in three possible ways; by the envelope of the note (the volume), the pitch of the note, or in a random mode. This gives variations ranging from a biting edgy funk tone, to airy whisps of sound (hence the name), from fusiony solo-ing with 'synth tracking' to dense shoe-gazy walls of distortion, guitar / electronic-percussion morphing... It's a hugely flexible palette of sounds that's never been possible before.
