Use busing to apply parallel compression
Enhance dynamics for compressed drum tracks
Compression can help give a bigger drum sound, but reduces dynamics. Mixing an uncompressed version of the drums in with the compressed sound can help restore punch.
Assign a Send from the drum’s audio track to a bus (e.g., Bus 1–2).
Select Track > New and specify a stereo Aux Input track (assuming the drums are stereo).
Assign the Aux Input’s input path selector to Bus 1–2.
Insert the desired compressor in one of the Aux Input track’s inserts.
Click on the drum Audio Track’s Send to Bus 1–2. The Send window opens; click on Pre so the bus level isn’t influenced by the drum track’s level.
Adjust the Send fader and Aux return fader for the desired balance of compressed drum sound with the dry drum sound from the audio track.
¦ Step 6: Sometimes it works better to set the compressed drum level first, then bring up the dry drum track to add dynamics.
