The G: make compression move with the part
Use attack, release and detector filtering to give drums, keys or a mix group a deliberate dynamic shape.

Give the compressor one clear job
The G suits group compression when several elements need a shared dynamic movement, or an individual part whose attack and body need a different relationship. It is useful on a drum group, a rhythmic keyboard part or a balanced mix group. Begin by deciding whether you want to retain the initial hit, pull the body forward or make repeated events breathe together.
Choose a loop containing different accents. Four identical hits do not reveal what happens when a fill, a louder snare or a bass note arrives. Keep a bypass reference at a similar level so you can judge the changed envelope.
Understand timing and level in the path
Ratio offers 2:1, 4:1 and 10:1. Attack offers 0.1, 0.3, 1, 3, 10 and 30 ms; Release offers 0.1, 0.3, 0.6 and 1.2 seconds plus Auto. These are discrete choices. A setting between printed choices is not an extra hidden timing option.
The sidechain filter changes the detector rather than cutting bass from the programme. Classic and Fat Berry provide different colour behaviour. Make Up raises the wet path before its colour stage, while Output is a cleaner final level adjustment after Mix. That distinction matters when comparing gain changes.
Workflow one: a drum group that keeps its first hit
Use a passage with kick, snare, cymbals and a fill. Leave enough room around the loop to hear recovery.
- Begin at 2:1 or 4:1 and choose a slower Attack option so the front of the hit remains available.
- Lower Threshold until the stronger events create useful gain movement. Hear the quieter hits between them.
- Choose Release or Auto by how the group returns before the next important beat.
- Raise the detector filter only if low-frequency events are making the entire group react more than you want.
- Match the final level with Output and compare the groove.
The aim is a connected movement, not a prescribed amount of meter activity. If the fill seems to collapse or the cymbal tail swells after every kick, reduce the pressure or reconsider the recovery. Keep the detector filter's role clear: it changes what prompts compression, while the whole signal still receives the gain change.
Workflow two: give a keyboard part more body
A short piano or electric-piano figure can have a pronounced front edge followed by a quieter body. Compression can change that relationship without rewriting the performance.
- Choose a phrase with soft and hard notes. Use a faster Attack option if the leading edge needs restraint.
- Find a Threshold that lets the quieter playing retain its character while controlling the stronger accents.
- Compare Classic and Fat Berry at similar apparent level, including sustained notes where colour is easier to distinguish.
- If the fully processed sound is too flattened, use Mix to restore some direct articulation.
Revisit Make Up after the envelope works. Because it precedes colour, adding it can change more than the final loudness. Use Output for the last comparison trim rather than chasing equal level with a control that also changes the wet path's operating point.
A creative use: parallel movement beneath a sparse beat
Use the plugin's Mix or a host parallel route to combine a more obviously compressed drum layer with the direct part. A stronger ratio and faster attack can create a sustained undercurrent while the direct signal keeps the main hit. Bring the compressed contribution in from quiet.
Hear the spaces as carefully as the hits. Room sound and cymbal spill may become the dominant result before the drum body gains much. A parallel layer is useful when its movement complements the groove, not merely because it sounds dramatic alone.
Commit the timing, then the colour
Once the rhythm feels right, compare the colour choice and final level again. Check a different song section before keeping the setting: a detector filter that helps a dense chorus may respond differently when the kick drops out.
The G is most useful when you can point to the changed relationship between attack, body and recovery. Preserve that intention when saving the session rather than treating a particular ratio or release as a universal preset.
