PREMIUM WORKFLOW

Built like an instrument, not a calculator.

Orbit View

Pulse, riff cycle and bar realignment shown as rotating musical timelines.

Grid View

16th-note guitar-first sequencer with chugs, ghosts, upstrokes and accents.

Target Realign

Choose where the riff returns to the one. CHUG-GRID generates the cycle.

Roll 3-6 rhythmic values and generate polymetric loops instantly.

Preset Library

Save riffs locally, reload ideas instantly and share playable riff links.

Export Tools

Download MIDI or MusicXML loops for DAWs, notation apps and guitar workflows.

REALIGNMENT ENGINE

Generate riffs that leave the barline and land back clean.

Choose a meter, bar target and style engine. CHUG-GRID builds playable picking grids, then shows the cycle against the bar.
