@d-healey Perfect, thank you very much!

@lijas90 I think this thread could help you

@lijas90 You need to add a generic script reference for the EQ then bypass it in the button callback

const var ParametriqEQ1 = Synth.getEffect("Parametriq EQ1"); const var Button1 = Content.getComponent("Button1"); inline function onButton1Control(component, value) { ParametriqEQ1.setBypassed(value); }; Content.getComponent("Button1").setControlCallback(onButton1Control);

@Lindon Thanks!

@d-healey Thank you so much! I finally got it to work, I’d been trying for quite a while😅
