Okay Synthesizer has released Okay Distortion, a free distortion plugin with six layered engines in a single reorderable signal chain.

I’m all for fun and creative distortion plugins (check out our free BPB Dirty Filter if you like this kind of stuff), so I’m always looking forward to testing another one.

The cool thing here is that this one wasn’t even planned as a standalone product originally. The distortion engine was built inside Okay Synthesizer’s Bingo Drum Machine, where it apparently became one of the most talked-about features.

Thankfully, the developer eventually pulled it out, gave it its own signal chain, and released it for free so all of us could have fun with it. And that’s more than Okay with me!

The six engines are bitcrusher, sample rate reducer, wavefolder, feedback, soft/hard clipper, and a pedal module. Each one has its own mix knob for parallel blending, and there’s a global dry/wet for the entire chain.

The killer feature is that you can drag the modules into any order, which completely changes the character of the output. Running the wavefolder before the clipper, for example, sounds very different from running it after.

The wavefolder uses the same code as in Okay Synthesizer’s awesome Bingo Drum Machine plugin. It takes signal peaks and folds them back into the waveform instead of clipping them, generating harmonics that standard saturation or clipping won’t produce.

The bitcrusher and sample rate reducer are more straightforward. It’s the typical bitcrushing setup for adding grit and lo-fi degradation to your audio.

The pedal module is a smooth blend between two analog circuit emulations. A Boss DS-1 sits at one end of the knob, a ProCo RAT at the other, with a tone control that works like a filter. Both sound pretty aggressive, and blending between them gives you a range of drive tones.

The feedback module is also fun for sound design. It takes the output of the entire signal chain, delays it slightly, and feeds it back into the input.

The gain slider controls how much signal is fed back, and a separate control adjusts the delay line length, which also affects the feedback. At low gain, it adds a bit of weight, but it can quickly become unpredictable as you push the gain (and that’s not a bad thing).

The soft/hard clipper rounds things off or smashes them flat, depending on where you set it. Both stages sit in the same module, so you can blend between gentle saturation and hard limiting within the chain.

I also like that there’s a built-in color picker that lets you change the entire plugin interface to whatever color you like. And it’s a super lightweight interface overall. I love the clean design.

Okay Distortion is available in VST3 and AU formats for macOS (Universal Binary) and Windows.
