Mastering.com's Logic Pro walkthrough shows how routing the Modulator's LFO to a Tremolo plugin's depth parameter turns a static sound into rhythmic, swishing stereo movement.
Dialing in the offset lets you control how gentle or aggressive the auto-pan feels, moving left to right in time with your track.
Collapsing the phase down to zero flips the same modulation into a mono pumping effect instead of stereo panning, using one routing setup for two distinct results.
The bigger takeaway: LFO and envelope routing to plugin parameters can push stock sounds into something that fits your own emotional and sonic direction, well beyond the preset.
