Yes exporting equal length samples from a DAW is not exactly rocket science if you align them vertically

Yes but be aware that multimic samples must have the exact same sample length, so you can‘t throw in arbitrary samples and abuse the multimic system as generic mixing device.

No, polyphonic mode is supposed to be polyphonic - all voices are rendered independently. If you can reproduce your issue, I'll take a look.

Oh that thing is broken since ages

Have you tried using your greenish slider colour for the highlighted keys? The blue is a bit distracting.

But sleak design.

Are you sure you don't set it to monophonic mode? Polyphonic is the 3x3 dot icon, Monophonic is the big circle symbol.

Ah, that's just the print function. If there are no digits, it will print an integer. If you need a certain amount of digits, use Engine.doubleToString():

Console.print(Engine.doubleToString(2.0, 2));

It works for Knobs:

const var Knob1 = Content.getComponent("Knob1");

Knob1.setRange(-12, 1, 0.1);
Knob1.set("saveInPreset", false);
Knob1.setValue(-2.0);

Console.print("Range: " + Knob1.getValue()); // -2
Console.print("Normalized: " + Knob1.getValueNormalized()); // 0.33

Haven't checked the other controls

I think it's a mistake in the API doc - it's created automatically by using the inheritance hierarchy of the C++ classes and this one might slipped in to the wrong place. Content.setPropertiesFromJSON() is definitely the go-to option.

However, the missing link might be a method like Control.getName() so you can call it without having to store the String name somewhere.
