MonoDelay: a lo-fi delay and noise instrument (VST/AU)

Hey elektronauts,

I make plugins under the name drop_out audio, just me, and MonoDelay is the first one out the door. Figured this was the right room for it. The synth this was based on I got around the same time as my Analog Rytm. When I went producing in the box (+ Overbridge!) I missed this one the most. So it feels like going full circle building this and posting about it here.

Demo first, because you’ll trust your ears over my paragraph.

It started as a PT2399 obsession (the echo chip in a stack of cheap delay pedals, and the toy synth this was based on) and turned into this. Three things I left in on purpose instead of engineering out:

  1. The sample rate sags as delay time goes up, the way the real chip does. Repeats get darker and grittier the longer they run. A SNEX node handles the dynamic ceiling inside the feedback loop.
  2. Tight headroom. Push the feedback into the MS-20 style filter peak and it pushes back, same as hardware would.
  3. A usable noise floor. It’s a source, not a defect. Drive it into self-oscillation and the thing turns into a drone and noise instrument.

It ships as both an effect and a playable instrument off one engine, with a ribbon keyboard on the VSTi side, so it sits on a send as a delay or runs as a noise voice next to your gear.

VST3 on Windows, AU and VST3 on Mac (Apple Silicon native). Built in HISE. There’s a 14-day full trial with nothing locked off if you want to throw it at a track first: dropout-audio.com. It’s 39 EUR for now if you end up keeping it.

Mostly I’d love your ears on it. Happy to get into the DSP if anyone wants. Tear it apart.

I’m a huge fan of the source of your inspiration and the audio in your demo video sounds very convincing to me, great work!

If I buy the auv3 should it run on both my mac and ipad?

Thanks for the kind words!

And sorry, no iOS support as of now and tbh it’s quite a side quest to get it there. I’ll take note of your interest in it though and if interest increases I might reconsider. :sunglasses:

Oops, I skim-read the text and my brain wanted to read auv3!

I use auv3’s a lot personally, but I have no idea if the market is large enough to justify porting it. It’s also nice when an iOS auv3 plugins can also run on my Mac because it feels like a lot of added value.

Is the filter post delay or in the feedback path?

It’s inside the feedback path, making it possible to resonate the feedback. :sunglasses:
