Free Plugin: Sonimus’s DelaySon

Good news for music producers and sound designers – Sonimus has dropped DelaySon, a free analog-style tape delay plugin for macOS and Windows.

If you’ve been around long enough, you might remember Sonimus from their SonEQ days. That plugin set a high bar for free tools, and DelaySon feels like a return to that same spirit.

DelaySon focuses on tape-style delay with warm modulation and tone-shaping. It’s not reinventing the wheel, but it nails the essentials with character and ease of use.

The interface is clean and dark, with sections for Color, Time, and Delay. You can switch between tempo sync or manual timing, push modulation for that wow-and-flutter feel, and shape your echoes from bright to dark.

The Color section includes a low-cut filter to clean up muddy repeats, while the Delay module gives you feedback that can run into self-oscillation, stereo offset for width, and Drive for extra saturation.

It shines on classic slapback delays for vocals and guitars, rhythmic echoes on synths and drums, or even pushing into experimental feedback and modulation-heavy sound design.

DelaySon runs on macOS and Windows in VST2.4, VST3, AU, and AAX formats, with full Apple Silicon support. You’ll need to drop your email on the Sonimus site to grab it for free.

Final thoughts: DelaySon doesn’t try to be everything—it just does tape delay really well. Whether you want subtle depth or wild psychedelic repeats, it’s a solid free plugin worth adding to your toolkit.
