What does that mean?

My guess is that a "soft pot" is one of these:

If you use it as a regular pot (like, say, a volume control) you lose connection when you stop pressing on it.

I think you will need a "digital pot" The "soft pot" is an input to the Arduino and the "digital pot" allows the Arduino to control the volume. See: https://www.maximintegrated.com/en/design/technical-documents/tutorials/1/1828.html

Yes that is a soft pot I wanted it to hold last value when pressed until I press another spot
