L-Ringmod

“Open Source Ableton Live Plugin that lets you frequency- and ring-modulate your input by side-chain channels or internal modulation oscillators. Features five different algorithms including FFT based relative FM. In order to user other channels as modulation source you’ll need to pan your carrier/input beforehand and then pick “Left -> Right” or “Right -> Left”. For this case there’s the possibility to offset and shift your sidechain’s frequency. Produces metallic soundeffects far beyond Live’s Erosion FM or Live’s Samplers Ring Modulation. Free Download, requires M4L.”
