SynthDef(\aalto, { arg bus;
	ReplaceOut.ar(bus, VSTPlugin.ar(nil, 2, id: \aalto));

//when done, free the resources!
~aalto.close;

Question: does the file path to Aalto get specified in this code? Or is the path to Aalto implicitly defined somewhere else in the server runtime?

You can run VSTPlugin.search; to get a list of currently installed plugins and then use the name listed for the plugin in VSTPluginController with the .open command.
