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.
