Why CHUG-GRID works for metal MIDI riffs

Most riff generators focus on notes first. CHUG-GRID starts with rhythm: chugs, ghost notes, upstrokes, accents, groupings and realignment. That makes it useful for guitarists, drummers and producers who write around pulse, displacement and odd meters.

You can generate a riff, edit the grid, listen to the pattern, save presets, copy a playable link, then export MIDI or MusicXML. The result is not a finished song; it is a strong rhythmic sketch that helps you get moving.
