REHEAT

A writing tool that happens to make sound

Basslines that write themselves. Pick a groove, hit new line, then take the MIDI and play it with whatever bass you already own. The synth is there so you can hear what you are getting — it is not the point.

The REHEAT panel — four gauges, a step grid, throttle levers and the transport.

What it does

It writes, you keep the MIDI

Every line can be dragged straight out onto a track. That is the whole idea — REHEAT decides the notes, your own bass makes the sound.

Ten genre grooves

Acid, hip hop, house, tech house, trance, techno, drum & bass, dub, disco and electro. Each one brings its own tempo, length and relationship with the kick.

Chords underneath, not just a scale

The generator moves through a real progression — root on the change, chord tones on the beats, passing notes between, and a chromatic lean into the turnaround.

A riff, not a random walk

One bar is composed as a cell and then played against each chord, so the line repeats and becomes a hook instead of wandering.

Locks to your kick

Feed the plugin your drum bus and it follows the beat, correcting its phase without ever restarting the pattern.

Any time signature

It is a writing tool, so it is not stuck in 4/4 — it follows the host's meter or takes one you choose.
