how do I get this effect to ‘notch’?
If you are talking about the native Para EQ in AA, then select V or inverted V shape and use only one band., then use the Q to expand/contract the range by dragging the node and using the handlebars.
I have one band selected. Where do I select the v or inverted v from?
If you need more visual control, head over to FabFilter Pro Q2
How’s that working for you @David
