Tempo-synced gain switching adds rhythmic emphasis a compressor cannot
Some balance goals need the track’s gain switched between levels in a regular tempo-locked pattern rather than compressed. With the song aligned to the grid you can mult the part to separate tracks, drive a MIDI-triggered gate from a metronomic pattern, or use a tempo-synced gate/chop/tremolo to, for example, lift off-beats or gate out in-between sounds — rhythmic control a level-dependent compressor cannot provide.
Examples
To emphasise a rhythm guitar’s off-beats without wrecking sustains, a MIDI-driven gate opened only on the off-beat notes raises those chords while a Range control keeps the on-beats present.
Assessment
Describe a use of tempo-triggered gain changes and the session setup it requires.
