Also, you can instantiate a controlport or xmlrpc server in your flowgraph and then send tuning commands their endpoints.
How you generate those tuning commands is up to you... I suppose someone who knows more about GUI programming than I do could come up with a touchscreen app that simulates a physical knob you can turn and emits various re-tuning events.
