RFM_LO-1

Back in the 70/80's of the last century it was pretty common to have a light organ connected to the speaker output, to get flashing lights for a specific part of the frequency spectrum... I wanted to recreate such a device, while also giving the added option of outputting the filtered signal... And as Request For Music's first published module, you can get it for free! Rejoice/relive the 70/80's and get those flashing bulbs...
