Sinusoidal Run Rhythm: Unfiltered Audio generates microtemporal groove in plugin

The problem this plugin solves

DnB groove isn't just about quantized timing or global swing. What sets a breathing break apart from a flat one is microtiming—subtle variations in the amplitude of each transient, the modulation of every attack. Until now, this was done manually: volume automation, sculpted sidechain, layered samples. Sinusoidal Run Rhythm by Unfiltered Audio offers a direct mathematical approach.

What the plugin does

The principle: Sinusoidal Run Rhythm takes any incoming signal and generates a groove pattern from microtemporal grids—sinusoidal oscillations that modulate the sound’s amplitude in sync with the BPM. The result: an algorithmic groove, not drawn by hand.

Developed in collaboration with composer Steffen Krebber, the plugin exposes several real-time modulation axes:

• Binaural shift – left/right differentiation of modulation to create spatial movement
• Panning – the groove generates a moving stereo image
• Cutoff frequency modulation (LP/HP/BP) – the filter follows the rhythmic pattern, not just the volume
• Multi-instance synchronization – multiple instances in the same project sync up, creating coherent groove patterns across tracks

A MIDI version is also available for triggering and external real-time control.

Why it matters for DnB production

Microtemporal processing is exactly what gives DnB sub-bass its texture, layered breaks their depth, and mid-range elements their "breathing" feel beneath the kick. Applying Sinusoidal Run Rhythm to a break loop that’s too rigid or a bassline lacking movement can introduce that organic grain without redrawing every automation.

Multi-instance synchronization is the most compelling feature: if the bass groove and break groove are mathematically linked, the result fits together effortlessly—where a traditional sidechain would require fine-tuning.
