FKFX Influx is an instant "Sonic Retox" engine. The resonator module (FLUX) goes thru a Low Pass and a Tube distortion. Flux resonator Note and Dry/Wet have their dedicated editors.

FKFX Influx lets you create new grooves from your current input. Selecting "WET ONLY" will output only the transformed part of the signal.

FKFX Influx comes with 82 Factory preset, plus 128 Extra preset you can get for free directly from Heat Audio facebook (link in preset list), so 210 presets.

I've thrown quite some weird stuff at this thing and it harmonized it with this unique distorting-ish approach. the aesthetic of the sound is actually something that i had in mind for quite some time but i couldn't reach for it with my other plugins. this plugin has some sort of texture that reminds me of old doors that start to make noise when you open or close them slowly. that sounds kinda bad, but i mean it in a good way, a really great way in fact.

I feel like a mad scientist when I use this thing! Insane visuals, never seen anything like it in an audio plugin. I'll be spending a lot of time playing around with this one.

@choomaque: have you already contacted the developer? I experienced a severe memory problem on my machine (with Obvious Filter), I contacted the dev and he fixed the problem within a day. I'm sure he'll do the same for you if possibile.

Support seems really quick and friendly to me. If you haven't aldready, drop him a line. I hope it helps.

I like Influx and Obvious Filter very much, actually. Cheers.

It works perfectly to me in FL Studio, and i love it. It gives extra sustance to drumloops or drums patterns in a glitchy creative way. I have been asking to something like this since years when KVRDC just began.

Have a good day.

I use the newest version of FL and use Windows 10. It works great and is a really cool plugin.

The Dry/Wet control only adds wet signal to the dry. It doesn't mix between the two. Is that the intended behaviour? (Running on Mac/Logic).

10 July 2021 at 4:00pm

Yes, the Dry/Wet knob is actually "Dry/Wet Max" as written, it will only adjust the final dry/wet, which is the is the curve itself (on which you can turn off all dry with "wet only" button).

OK, thanks for the info.
