@Goodflow said in Can someone explain front-end macros to me?:

I think you can put constant modulators in the Macro Slots, assign those constant values to be controlled by corresponding user knobs (visible or not), named “Macro 1,2,3,etc”, and make those user knobs ispluginparameter=true. Then your external modulator can control the values feeding the constant modulators.

That might work, I'll give it a try, thanks. I'm not sure I need to use constant modulators though - or a modulation container at all.
