Hey all,

Just released SWRL and SWRL Lite from FRCTL Audio (some of you might know me from GRN, the granular plugin).

Image

SWRL (Swirl) is a "movement effect". It runs 6 different DSP processes in parallel and blends them together into one combined texture. The idea came from wanting to have a single plugin that could "bring life" to stale sounds. Like GRN I wanted to make it easy and fun to use and experiment with.

The 6 "characters" are:

Drift — pitch wobble and chorus, kind of like tape drift
Wash — reverb and diffusion
Orbit — spatial circular panning
Flutter — fast tremolo and stereo flicker
Pulse — tempo-synced rhythmic gating and pumping
Heat — warm saturation

SWRL Lite is free and has two knobs: Amount (how much effect) and Mix (dry/wet). That's literally it. Throw it on something, turn the knob and done + cool visualizer of course.

The full version has individual control over each character's amount, plus adjustable rate, stereo width, crossover filters, output filters, autogain, meters, spectrum analyzer.

Available as VST3, AU, and CLAP on Windows, Mac (universal binary, signed and notarized), and Linux (You know I got you).

Happy to answer any questions. Would love to hear how people use it if you give it a try.

Also here's a quick video I made of what the effects sound like!

Just got an email about SWRL 1.2.
Every character in SWRL now has more than one voicing. Right-click a knob to pick one. Heat can run as a tube, tape, a transistor or a wavefolder. Wash can be a tight room, a bright plate, or a big dark cathedral. The other four have their own sets. Same six knobs, a lot more range.

Also new in 1.2.0:

- A stereo imager to watch your stereo field while you dial.
- 19 new presets, 85 in total.
- A resizable window, and a Chaos control that sets how far the random button goes (Right click the random button to open the slider).

All of these new knob settings are great. FRCTL plugins always have super musical settings.

If something is too dry and obvious sounding, I can find a way to make it melt into the track and sit right and sound interesting with SWRL.

I honestly didn't think I would use this plugin as much as I do.
