Set Rate around +8dB and OUT around -8dB.

Lower ratio values produce a more natural sound, while higher values intensify the compression effect.

KNEE adjustment is crucial: hard knee creates a steep curve to the peak, pushing the groove forward; soft knee creates a gentler curve, pulling the groove back.

*Example
Adjust the relationship between kick drum, snare, and bass using KNEE instead of volume, or match claps and piano with exaggerated soft knee against forward-pushing hard knee vocals so that increasing the volume of the latter doesn't bury the vocals.

During recording, when converting kinetic energy to electrical energy, the reverse-polarity transient is attenuated compared to the kinetic energy source.
Therefore, when converting back to kinetic energy through speakers, the transients lost during recording need to be reformed.
With upward expansion, it's easy to control decay using HOLD and RELEASE values.
By deriving the note value in milliseconds from the track's BPM and applying it to each parameter of the expander or compressor, you can easily perform high-level mix processing that is both electrically and musically rational, with more freedom than sidechain compression.

Glue Comp is used in bus and mix master processing for each part to literally add "glue" and cohesion to the sound.

Since the emphasis is on unifying overall behavior with larger note value waves, longer note releases are preferable compared to individual tracks.

Since it's basically blended with dry/wet, you can set ATTACK fast and reduction deep.

Check if the desired behavior is achieved while exaggerating pumping at 100% WET, then blend with DRY.

Sound cohesion can be easily controlled with blend ratio and knee curve.

While the approach of unifying everything with large note waves keeps individual tracks at 8th or 16th note values, and since RELEASE value is fundamentally the core of that track's wave (groove), if kick and snare are set to 8th notes, hi-hats and tambourines can have RELEASE set to 16th note values to emphasize the 16th note wave.

By setting RELEASE based on what note value expression the part being processed is responsible for in the arrangement, you can perform processing more closely tied to the music itself.

Also, since you can confirm the effect just by changing the RELEASE value, it's overwhelmingly easier to set and compare than operating compressors by feel.

For drums like kick and snare where there's significant lag between the strike and resonance, this same technique can substantially supplement the sustain and reaction expression of kick and snare that are difficult to capture and express.

These processes are also very effective in preventing situations where exaggerated upward expansion processing would create unnatural dynamics.
