Tokøta from Mastering.com walks through Logic Pro's Learn Assignment feature (Command-L), showing how to map any knob or fader on a MIDI controller directly to a plugin parameter.
Click a control like filter cutoff, hit the shortcut, then move a knob on your controller. Logic picks up the input and links it instantly, no menus or CC numbers required.
The same process assigns volume, panning, or any other parameter, giving you several knobs controlling different elements at once. Moving them while the track plays lets you record those tweaks as automation in real time.
This turns mixing into a tactile, performative act rather than a mouse-driven task, useful both for shaping a track in the studio and for controlling parameters live on stage.
