Cells!

Cells! is an add-on for Renoise 2.8 that turns the cross-platform audio tracker into an real-time performance tool. It supports the triggering of audio loops and samples, complete with per track ‘DJ-style’ effects (bass kill, filter etc.) all quantized in time to the current tempo. It supports multiple outputs to separate the main playback output and cue output. Emphasis is strongly upon the live performance aspects.

Device "step by step (oh baby) simple sequencer" (or swapper...)
With both a live and a write mode, and random features!
