About

KR8

Features
Read full description

KR8-0 is a drum machine for live performance. It runs a step sequencer with 16 to 64 steps, four drum kits, per-channel mute and solo, per-channel volume, and a BPM range of 40 to 220. The audio engine runs on a dedicated thread separate from the UI, so the tempo holds regardless of what's happening on screen. Four kits are included. The default kit is synthesis-based: each sound is generated from mathematical waveforms and envelopes computed in real time, with no sample files involved. The three additional kits are sample-based, using recorded drum sounds loaded from audio files on the device. No internet connection is used at any point. No account is required. No data leaves the device.

Groove Destroyer isn't a gate, stutter, or glitch effect. Instead of chopping your audio into predictable patterns, it continuously reinterprets the groove underneath your music. Rhythms shift, accents evolve, filters dance, and movement emerges that feels alive instead of programmed. At the heart of Groove Destroyer is an intelligent groove engine that generates evolving rhythmic events while preserving the underlying pulse. Resonant filters, animated movement, saturation, and controlled instability combine to produce textures ranging from subtle motion to complete rhythmic mayhem. Use it on drums, percussion, synths, guitars, loops, vocals, or entire mixes whenever you want movement that sounds organic rather than mechanical. Whether you're adding a little instability or pushing a beat to the edge of collapse, Groove Destroyer creates grooves that never play exactly the same way twice.
