Better way to call methods for gsp without defining Renderer type == Speaker

[haku5hu]

When I call stuff on the granular sample player outside of the setupAudio I get errors unless I put it in if(renderer.type == type.speaker).

Is there a better way to think about this or can this if statement be hidden? It's inconsistent because I don't need to define the type for doing light stuff

Note this is all on the simulator.
