Looks promising

UPDATE: It crashed Reason on first usage (R13 on Win 11). I ran again and no dramas. The difference I was aware of was that first time I resized the GUI.
It is on ok thing, but I never understand how these days echo modulation is missing or a half-implemented afterthought.5 secs seems generous but simply makes the knob too coarse for the section that matters (in Seconds mode - BPM Sync being for babies hihi). Spring is pretty nice. Ultimately tho, not a keeper as between The Echo (Reason stock Delay) and my own VST like 2020 Modulating Delay to 4-lines Later, this doesn't bring me anything particularly different. To be fair, I would be surprised if it did.

I have many delays myself, some that I got because of the features, some because of the sound. I guess this one falls more towards the "sound" side of the equation for me. (And because it's free.)
A well-behaved signature.

Linux version is working nicely. Nothing startingly new with the delay but sounds nice esp. with the drift. Really like the reverb which makes it a keeper for me, not exactly subtle but something about the spring character does it for me.
And native choices on Linux are always welcome.

Been testing it a bit those last days, the delay section is cool, but I like very much the set of features in the spring reverb section, it's rare even with commercial products to be able to "sound design" a spring reverb sound like here, very nice plug-in even more since it's free

Yeah, I just gave it a quick try, and the spring reverb is what got my attention. I generally don't like spring reverbs, but this one is pretty neat with all of the control options.

Excellent freebie, thanks for pointing it out.
The GUI vaguely reminds me of the free Ambience reverb by one of the Smart Electronix guys from many moons ago.

I couldn't get it to run on my Reaper/Windows 10 setup - it kept crashing. I contacted the developer via Github and he has now fixed the issue.
I agree that the Spring reverb is different and highly customizable. Nice tool.
