It's been a while but as far as I remember this could be accessed by scheduler and UI threads.

I know this is existing code, but do we really need dynamic here?

I think this was dynamic since it was originally intended to be applicable to different types of input nodes, not just sliders. In the next line, it uses the Value property, which isn't defined on the NodeModel class, but which is the common base class for all nodes (input nodes in this case).

so it sounds like you don't need dynamic you need to use the common base class or an interface etc?

I think using the dlr has significant performance implications.

I guess we could introduce a new interface with a single Value member.

I actually think that @twastvedt wanted a similar interface for accessing input nodes in player without referencing the actual NodeModel types.
