Each track contains five sends, located in the Effects And Sends panel in the Audio Mixer. Sends are often used to route a track’s signal to a submix track for effects processing. The submix can return the processed signal to the mix by routing it to the master track, or it can route the signal to another submix. A send includes a level knob that controls the ratio of the send track volume to the submix volume. This value is called the wet/dry ratio, with “wet” referring to the effects‑processed submix signal and “dry” referring to the signal from the send track. A wet/dry ratio of 100% indicates that the wet signal is output at full strength. The submix volume affects the wet signal, and the send track’s volume affects the dry signal.

A send can be applied pre‑fader or post‑fader, and the outcome is that the track audio is sent either before or after the track’s volume fader is applied. With a pre‑fader send, adjusting the track fader doesn’t affect the output level from the send. A post‑fader send maintains the wet/dry ratio, fading the wet and dry signals simultaneously as you adjust the send track’s volume.
