Great tool!

A awesome plugin for depth and sound design

Really Stellar Plugin

I'd been struggling with creating long ambient stretches using a sample or short melody without making it sound too boring or inconsistent in density. Experimenting with delays and reverb via various VSTs combined is cool and all, but a little time consuming. I've only had this for about a week, but I've been able to create some pretty awesome ambient backdrops to my tracks in just a couple minutes. I really like how well it has streamlined something that would otherwise take me 10-30 minutes fooling around with. I love that it's all in one.

My only critique is that is doesn't play super nicely with reaper atm, and I have to close the VST window to resume editing, as it seems to freeze up the reaper gui. That said, I'm willing to workaround that for some awesome results.


I. AM. ABSOLUTELY. STUNNED. I've tried this plugin on multiple of my Songs a not one of them sounded bad or unnatural. 5/5 JUST PERFECT!

Really cool plugin 👌

This is really cool! Definitely feel the tension with that dark atmospheric vibe, when I use it for synths. Even tried it on guitar as well, and get some interesting character to the sound. I'll combine this with JST Heat, and I get aggressive unique sound to my mixes!
Alot of fun for making some videogame soundtracks!!
