By using a third party module it is possible to avoid using a PatchMemory Float Out3 module in the LED2 control. It can be replaced with a QTN_Float2GUIFloat, to convert from DSP Floating Point to GUI Floating Point.
By setting Input 2 to a value of 10 V the LED will “Illuminate” at 5 V on the Signal In plug.
Note: If you set the Input 2 plug to 0 the LED will always be “On” (You cannot divide by zero, so the module will not provide a valid output.
Note: If you want to provide a quick and easy “Clipping detection” LED, then Set Input 2 to 1V, and change the Response plug on the Volts to Float module to “Clip Detect”. This will provide a fast method of clipping detection.
By adding another Divide module connected to Input 2 of the original Divide module, and setting this new module with an Input2 value of 2V we can then provide a second input with which to set the voltage at which the LED “Illuminates”.
Colour changing LED.
We can also add another similar input chain to give control over the LED colour. If the Input2 of the divide is set to 10 this will allow an input voltage of 0 V to 10 V to control the colour of the LED. If you want to colour change in response to a variable voltage I would suggest setting the Response of the Volts to Float to at least 20 Hz to avoid the colour change looking “stepped”. You can see this in action by connecting up a slow running oscillator, but don’t forget that this will give a -5 V to +5 V voltage swing, so you’ll need to ad a 5 V offset to the colour plug to get the correct range.
