"Freeze" would only affect the graph, not the parameters that are still
dynamic.

On/Off and Bypass would be parameters. I'm not sure i get the scenario you
describe, but "off" would be a switch at the front that doesn't do
anything with incoming data and does output a fixed zero while "bypass"
would act like a bridge, just feeding input to output (*1 if you like).

DAW would be a set of widgets, controls and views  "orchestrating" the
blocks. I know that's too much simplified still not completely crazy to
think about IMHO.
