If you’ve been around BPB for a while, you’ve likely heard the impact of some of Ewan Bristow’s weird and wonderful creations. His latest release is UZU, a frequency domain filter, inspired by Harmor’s Phaser.
Ewan is a Bristol-based (UK) developer who has given us freebies like EB-CatNip (frequency-shifting delay – Plugdata), EB-Diøne (sampler – Plugdata), and the more recent, LOCD (phase-lock distortion).
This time, Ewan is back with a new plugin that should delight FL Studio users and excite others who perhaps missed out on some Image-Line gems!
I mentioned recently that I hadn’t had much experience with FL Studio, but I always got the impression there was a loyal community behind it. It reminded me of how keyboardists were quite precious about Yamaha Motif presets back in the day, myself included.
Ewan’s latest plugin, UZU, is inspired by Harmor’s phaser; Harmor is an additive-subtractive synth by Image-Line (included in the All Plugins Edition of FL Studio).
The aim is to deliver what many consider an iconic sound, an effect that can be used freely anywhere.
UZU is available for purchase for $17 in AU, VST3, and CLAP formats, supporting macOS, Windows, and Linux.
In even better news, Ewan is making UZU available for free for 48 hours if and when he hits 10K followers on Twitter/X (he’s not too far, so get involved).
Although Harmor isn’t exclusive to FL Studio (it’s available for use in other DAWs), I feel it’s better known to FL Studio users and producers of certain electronic genres, but might be one of those hidden gems for others.
If, like me, you’re new to Harmor, it doesn’t take much effort to find people swearing that it features the best phaser ever (and others explaining how it isn’t really a phaser because it doesn’t take the traditional all-pass filter approach) – it’s interesting.
Ewan’s UZU is powered by spectral filtering, offering up to 8192 notches, to mimic the precision and control offered by Harmor’s unconventional phaser.
The first three dials on the intuitive interface are Width, Offset, and Depth; controlling the width of the spectral notches, the phase of the spectral filter generation, and interpolation between thin/thick notch sizes, respectively.
The last three dials are Speed, Mix, and Blur, and there are a couple of really interesting elements. You can create the obvious glitchy electro sequences or growls, and they sound fantastic, but with the Blur parameter pushed up, you can transform lackluster sounds into beautiful, spacey, chilled pads.
You can also multiply the effects of the Offset and Speed parameters 1X/5X.
UZU goes even further toward carving your sound with precision by allowing you to adjust the number of samples fed into the spectral engine and move between hertz and octave notch distribution.
There’s even a Keep Bass function, applying a 250Hz low-pass filter to ensure all your bass gets through.
UZU is a plugin with countless applications, and it should feel like Christmas has come early for Harmor fans.
Keep an eye on Ewan’s posts for updates on the possible 48-hour free-for-all, and go check out his YouTube when you have time.
Ewan has gone from strength to strength with recent releases, and it’s fantastic to see a very talented guy with creative ideas be so passionate about giving back to the bedroom producer community.
