Place chords on the fretboard. Sketch guitar parts with strumming patterns. FretMachine is a guitar chord and strumming sequencer for musicians, producers, songwriters, and DAW users. Unlike traditional tab-based workflows, FretMachine provides a more intuitive way to create guitar parts. Place chords on a fretboard-style interface, create strumming patterns in the rhythm sequencer, and arrange your ideas on the timeline. When you place notes on the fretboard, FretMachine analyzes the shape in real time and shows you the chord name. You can also choose chords directly from the chord library and quickly build chord progressions. Once your chords are ready, create strumming patterns on the rhythm grid, arrange them on the timeline, and export your ideas as MIDI files for further production in your DAW. KEY FEATURES • Strum-Based Sequencing Create guitar ideas around chords and strumming rhythms instead of entering notes one by one. • Pattern-Based Sequencer Arrange strumming and rhythm patterns freely on the timeline to structure your song ideas. • Chord Library Supports Basic Triads, 7th chords, tension chords such as 9th/11th/13th, sus/add chords, Altered chords, and a variety of guitar voicings. • Reverse Chord Finder Place notes on the fretboard and see the chord name analyzed in real time. • Fretboard Input Enter and sequence chord shapes while viewing a visual guitar fretboard interface. • Rhythm & Strumming Pattern Editor Design strumming rhythms on a grid using downstrokes and upstrokes. • MIDI Export Export completed guitar parts as MIDI files and bring them into your DAW. FretMachine helps you quickly build guitar-focused ideas, from chord sketches to pattern-based song drafts.
