How To Make Ducking Delays In Logic Pro

From a mixing standpoint, ducking your delays makes a lot of sense. If you need the level of your delays (the wet signal) to be softer when the source (the dry signal) is present, then sidechaining the delay is the answer.

Here’s a way to set up ducking delays, and to make them behave a bit more organically in Logic Pro. Once you have this set up, you’ll see that using this concept opens up a world of creative possibilities, without using any automation.

Setting Up Ducking Delays In Logic Pro

  • Put a 100% wet delay plugin on a bus so you can send to it.
  • Insert a compressor right after your delay plugin.
  • Choose your source track as the compressor’s sidechain.

You’ll have some tweaking to do yourself, but now your source track is controlling the volume of your delay signal, which really helps keeping focus on your vocals, or any sound for that matter.

Let’s take this concept a bit further:

Audio 1 sends to Bus 1, where delays are ducked by Audio 1 with Compressor. Audio 1 sends to Bus 3, where reverb is ducked by Bus 2 with Compressor (that’s why Bus 1 has output Bus 2, so I can reuse that signal for sidechaining).

So now, when there’s a vocal, there will be reverb. When there’s silence, delay. Options are endless here, once you have this set up it’s easy to change your effects. A delay plugin that has an auxiliary input option for ducking is PSP 85, it’s the only one I’ve seen sofar that offers this. Also, there’s a freebie ducking delay available for download at the Mdsp @ Smartelectronix website.

If you know of any other delay plugins that have a sidechaining feature, drop me a line in the comments!
