Synth.getAttribute() not recognised

[d.healey]

I've just noticed that Synth.getAttribute() triggers a function not found error. Here's a little demo project

The Synth.getAttribute() method is working, but you need a getAttribute() method for connected modules, which was indeed missing. I added it for all module types.

BTW, it is a bit more efficient (and more compact) to write toggle behavior like this:

MidiMuter.setAttribute(0, 1.0 - MidiMuter.getAttribute(0));

because you'll get away without branching...
