I'm not sure if it is still produced but the Dudley breath control uses two
tubes, left, right & both for forward. Suck does the reverse.
Having thought for a second, this probably means you need some logic to
convert it to the signals that the DX needs or perhaps the Wisedx or the
click & go could cope. Does anyone know ?
