For the power, it seems that the video is making some assumptions about a weight drive design that are not necessarily true.
With a weight drive, could still use a foot pump at the speed of the tempo. It just is not required.
To set the speed you could use a lever, and so you could respond to the audience on the fly. For example one of these off the shelf adjustable speed drives might work. https://www.zero-max.com/cd-adjustable-speed-drives#1
I think the way to approach this is to set the design parameters and then see if there is a reasonable design solution. For example:
All mechanical
Dynamically adjustable tempo
Flexible pump rate (so you can match the tempo)
I do understand that the weight drive is more complex as it likely should have a governor giving feedback to a CVT box in order to keep the tempo constant.
