Keylay Is A FREE Ping-Pong Delay Effect By Baby Audio


Keys Magazine offers Keylay, a freeware stereo ping-pong delay plugin developed by Baby Audio.

Baby Audio developed Keylay exclusively for Keys Magazine, and it’s available in AU, VST, and AAX formats for macOS and Windows.

If Keylay looks familiar, it’s because it’s a clone of Baby Comeback, which is a stripped-down version of Baby Audio’s Comeback Kid.

Baby Comeback was developed in conjunction with Computer Music Magazine and is also free to download. So, what’s different about Keylay?

On the surface, it has a new skin and color scheme with the Keys Magazine logo. Beyond that, it comes with 4 exclusive presets put together by Keys Magazine editor Carl-Phillip Schmeller.

This free version features the same delay engine and audio ducker that you’ll find in the Comeback Kid plugin. Essentially, it delivers the same quality while having a slightly smaller feature set.

If we go through the GUI from left to right, we start with four different flavors; Wide, Long Tail, Psy Delay, and Dub.

Wide expands the stereo image slightly and has a modern sound. Next up is Long Tail, which does exactly as the name suggests. Psy Delay adds some movement on the tails and could be good for synth strings or pads. Lastly, we have Dub, which gives the tails more of a sweeping feel.

The Baby Comeback plugin, mentioned above, has four different flavors/presets, so there’s no harm in grabbing both if you feel like comparing them.

Everything else is straightforward; the delay section controls time, feedback, note-type (straight, dotted, etc), and a ping pong function. There is a free note setting that allows you to set delay times that aren’t synced to the host.

The output section is where you’ll find the ducker, which is great if you are working on a kick or even vocals and don’t want delay overkill.

Baby Audio has gone for individual dry and wet output knobs rather than a single dry/wet mix. That wraps it up, it’s easy to use, good quality, and it’s free!

Baby Audio has also released the free Baby Audio x nu.wav sample pack. The free sample pack includes 100MB of versatile loops created by the nu.wav sound design house in NYC. All loops were created using Baby Audio plugins for all processing.

  2. Hey James, no one seemed to tell about this here, so I am telling. This is a cool new filter plugin from a developer on Patreon – . This thing is high quality and the GUI looks amazing. But FL Studio and Bitwig users are facing issues with this plugin as the plugin is not taking any input, though it’s working fine in Cakewalk, Waveform and Reaper as far as I can tell.

      Hey In A Week, we’re working on an article about this freebie. It will go live today! Thanks for your support. :)

    • Fixed buffer size (in wrapper settings) is often a fix for various issues in FL Studio. Maybe worth trying.

      • Hi Christian H,
        I tried to to do this, but the plugin doesn’t seem to work in FL at all. Many users are are also saying that it doesn’t work in Bitwig too. Anyways, I have Cakewalk and Waveform, and the plugin works fine in them, so no issues. I do hope the developers fix this in the next release.

        • use the baby comeback is free too and almost the same.I love that one and works nicely in my fl studio.

    I don’t understand…
    Is it the same plugin as Baby Comeback ?
    Because it’s not the same function’s names (long tail, psy delay…).
    And your link does not work, it’s Baby audio website (Freebies section), but no Keylay…
