# Compress MIDI velocity in Reaper
I prefer using the MIDI Velocity Scaler/Compressor JS effect, since it's nondestructive.
Alternatively, highlight all notes, right-click a note, and select Event properties. In the velocity box, enter `*.5` or `/2` to apply 2:1 compression.[^1]
In the case of drums, you can right-click the key that corresponds with the drum that needs to be compressed.[^1]
