Generate Shepard Tone with Retrologue 2

Hi,

Does anyone know how to create a Shepard Tone with Retrologue 2?

I am watching this video: https://www.youtube.com/watch?v=DxXlv4r1bgo

The issue I am having is that now sure how to set up the LFOs ( specifically one-shot/single cycle waveform for LFO types!)

Any help would be greatly appreciated.
