samplers_Start[i] = Synth.getChildSynth("Names")

For a Round Robin change I wanted to make I realised I needed the samplers as get.Sampler() references so I can do .setActiveGroup()
But then I realised that my Sampler bypassing function wasn't working anymore:
It works again if I change it back to Synth.getChildSynth() instead, but I don't understand why this is this way....

// REFERENCES
const s_Child = Synth.getChildSynth("Sampler1");
const s_Synth = Synth.getSampler("Sampler1");

// --- Using setBypassed
s_Child.setBypassed(1); 	// Works
//s_Synth.setBypassed(1);  	// Doesnt work

// Set Active Group
//s_Child.enableRoundRobin(0); 	// Doesnt work
//s_Child.setActiveGroup(1); 	// Doesnt work

s_Synth.enableRoundRobin(0); 	// Works
s_Synth.setActiveGroup(1);		// Works

for(i = 0; i < 20; i++)
{
	Console.print(s_Child.getAttributeId(i)); 	// Works
	Console.print(s_Synth.getAttributeId(i)); 	// Works
}

I think I have some general confusion in this area and I sometimes don't know whether to look for a API method or a documentation Property, or when to do .getAttributes().
