How do I connect a knob to a CC controller using code?

@CatABC You can use the on controller callback to get the incoming value of the CC and then set the knob's value.

@d-healey Thanks a lot for the tip, I succeeded， Treat you to watermelon, even though it's just an Emoji，But I really mean it.

	local number = Message.getControllerNumber();
	
	    if (number == 1) { 
	    
		   local ccValue = Message.getControllerValue();
		   Console.print(ccValue);
		    
	       local inputValue = ccValue / 127;
 
	       Console.print(inputValue);
	       
	       knb1.setValue(inputValue);
	       
	      
	    }

@CatABC If you want the knob to represent the actual MIDI values and not a normalized value you can set the "min", "max" and "stepSize" of the knob to reflect that:

knb1.set("min", 0);
knb1.set("max", 127);
knb1.set("stepSize", 1);

If you do that you would just get rid of of the "inputValue" variable and use the "ccValue" directly to set the knob value.

@VirtualVirgin Cool, thanks for your suggestion, it's very useful
