Osculatrix is a tremolo with ideas above its station. With modulated filters, delays, a bit of saturation. Like its predecessors, it is cryptic and opinionated, and it goes from subtle colouration to total destruction at the twist of a knob. Osculatrix is an AUv3 effect plugin. It does nothing on its own. Use it in GarageBand, AUM or your favourite audio application. Osculatrix does not want your money and it doesn't want your data. It is 100% free. No ads, no in-app purchases, no subscriptions, no surveillance, no nag screens.
