Lotus Sound Releases FREE ADM Delay Plugin


Lotus Sound has released the ADM, or Analog Delay Machine, a free delay plugin for Windows and macOS.

And we’re back with yet another delay plugin!

ADM is different from your typical free delays and packs four independent lines into a single plugin interface. The sound of the delay is quite lovely, and I did find myself enjoying the atmosphere it brings to things.

The manual seems to be curiously absent, and there isn’t really a usage guide. Thankfully, I took the liberty of forcing this thing to do weird stuff so I could figure out what does what.

The interface is divided into two distinct sections. The leftmost section has four delays, numbered accordingly. This is where your delay controls reside. I couldn’t see a way to force it into free running, so you’re stuck with time-synced delay taps.

They’ve got a good bit of range, however. You can readily slap it from 1/128 to 1/2 with ease. Each of these seems to also be stereo delays, from what my ears could infer.

The rightmost section is where the actual controls come into play. You’ve got a feedback knob, the one you know and love at this point.

I found the range on this to be a little fuzzy, as I could barely tell what was happening at, say, 20-30%, but 60-70% sounded about normal to my ears. This is coupled with a filter, which is a curious control. At 0%, it makes the delay lines fairly clean.

At 100%, however, you get wonderful atmospheres, which I guess is modulation or a diffusion network coming into play. You’ll want to leave it at 100% if you’re after some lush sounds.

This is capped off with a dry/wet knob. I did find that 30% was my sweet spot for insert effects. I typically don’t run delays as a send so I can have different tap lengths for different materials.

That said, it sounds wonderful.

ADM is available for Windows and Mac computers. Supported plugin formats are VST, VST3, and AU. I couldn’t seem to get the VST to function on my Windows machine, but the VST3 works just fine on my Mac and Windows computers.

  1. Well, there’s five plugins on the website, including the ADM and it says they’re all free (no mention of a limited time offer, so you may want to look into that).

      – Yeah, looks to be the case. The “number of downloads” number could just be how many times these were downloaded so far.

    • And all of them are excellent, super plugins
      for audio production, for my taste and needs,
      thank you so much creating them, thank you!
