Music synchronized light modulator

A system comprising:

• a host controller;
• one or more strings of light, each string of light comprising at least one LED light;
• and
• an effects modulator operatively connected to the host controller and to the one or more strings of light, the effects modulator comprising:
• a microcontroller, and
• an inverter configured to supply a voltage across each of the one or more strings of light, the inverter comprising a high side driver circuit and one or more low side driver circuits operatively connected to the high side driver circuit, each of the one or more low side driver circuits operatively connected to one of the one or more strings of light,
• wherein the microcontroller is configured to receive one or more control signals from the host controller and control the one or more strings of light via the inverter in accordance with the one or more control signals so as to alternate a polarity of the voltage for each of the one or more strings of light between a positive polarity and a negative polarity during operation of the one or more strings of light.
