A named control for modulating multiple parameters, with an optional MIDI CC binding.
A macro’s own value is itself a modulation target: assign an LFO, another macro, or any other source to it like any other parameter, including self- or cross-macro modulation.
Mixer Mode has a separate, fixed set: 4 macro knobs per deck, each with its own independent MIDI CC binding. These are scoped to their deck rather than to the patch, don’t grow, and aren’t modulation targets.
