Sinusoidal Sine-Fight: Metamyther Gets Weird with Unfiltered Audio’s Run Rhythm

If you thought sine waves were only for tame LFO wobbles, think again. Metamyther kicks things off by introducing Sinusoidal Run Rhythm – a plugin that ditches the grid and smashes together multiple sine waves to cook up modulation patterns that border on the unhinged. The brainchild of composer Stefan Kreber’s fresh theory of rhythm, this plugin isn’t here to polish your hi-hats; it wants to inject movement and unpredictability into every parameter you dare to modulate.

The result? Instead of another square-pushing step sequencer, SRR uses rhythmic wave interference to create evolving, clocked (or unclocked, if you’re feeling brave) pulses that can get subtle or absolutely bonkers. It’s a proper weapon for those who crave anti-static tracks, and Metamyther’s intro makes it clear: this isn’t your gran’s envelope follower.

Straight into the meat of it, Metamyther shows off SRR’s main panel – and it’s all about piling up partials. Each sine wave (partial) adds its own chaos to the mix, letting you sculpt everything from smooth undulations to angular, syncopated nonsense. The master rate and phase controls are your launchpad: speed it up, slow it down, phase-shift until the waveform looks like a rave bunker light show. No maths degree required – just twist and listen.

There’s also a global depth dial if you want to tame things, plus modulation for amp, filter, and panning – each ready to go from whisper to full-on toaster-fight. Filter types include familiar Unfiltered Audio flavours (dark LP, gnarly comb, and more), so you can sweep, crunch or widen your sounds at will. It’s dangerously easy to get lost patching wild curves, but that’s half the fun, isn’t it?

Just as you think you’ve tamed those sine waves, Metamyther throws on the sample and hold – turning your fluid LFOs into abrupt, stepped shapes. It’s like swapping a smooth operator for a stuttering robot, and thanks to the morph control, you can dial in just how jagged you want things. Slide the morph to taste – from clicky square waves to more rounded, musical patterns.

SRR doesn’t stop there; you can further carve up your modulation shapes using sliders that tweak the curve behaviour, pushing things even deeper into glitchy territory or smoothing it all out for subtle movement. Want a strobing tremolo or a digitised gate? Easy. This section’s a goldmine for anyone bored of vanilla mod sources.

Now here’s where it gets properly spicy: Metamyther jumps over to SRR’s MIDI version, letting those wild sine concoctions break free and modulate other plugins anywhere in your DAW. Setting this up is a breeze in Ableton – just route SRR MIDI to your target synth, pick a CC (mod wheel’s a favourite), and let the madness begin. Suddenly, you’re not just modulating one track; you’re waging a modulation war across your whole project.

The demo with Newfangled Audio’s Generate shows how SRR can animate even the most static patches in seconds. If you’ve ever wanted your entire mix to breathe and convulse in sync with a single, unruly source, this is your ticket. It’s a feature that turns SRR from a mere plugin into a full-on modulation nerve centre.
