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.

Features
Read full description

No sequence. No play button needed. An instrument that keeps going without you programming anything. Two generative engines invent phrases endlessly inside the scale and chord you choose. What you shape is not a song — it is a way of sounding. Move a control and the sound changes shape without ever stopping. Density, contour, filter, tape movement. It is built so that nothing you touch can break it. And you can play it. On the key pad or from a MIDI keyboard, right on top of the stream it is generating. What you play can be captured into the looper. Now your own sound can go in too. Record a bar into SAMPLE, the fifth machine, and chopping it up and rearranging it is the app's job. ■ Generate • Two independent arpeggio engines (waveform, filter, envelope, effects) • Eight arpeggio types, chord progressions, ten time signatures • BASS — a bass machine of its own (STEP / COMPLEXITY / OMIT / PATTERN) • Drum machine • Six LFOs, XY pad, performance FX ■ Slice (SAMPLE) • Record one bar from a mic or line input, with count-in and click • Record the app itself (ARP A / ARP B / drums), and overdub onto it • Load audio files — and the audio from a video file • Up to 32 slices, ordered by the same rules as the arps: direction, reverse, octave, probability, groove • STRETCH (on by default) — change tempo without changing pitch • Its own filter, envelope and delay / reverb sends ■ Play • On-screen key pad — always in scale • MIDI keyboard input (damper pedal, pitch bend, standard control changes) • One-bar looper that records how hard you played ■ Sound • Piano — three velocity layers, stereo, damper release • Electric piano — harmonics shift with how hard you strike • Kalimba, handpan and chime — struck metal, measured from the real instruments and synthesised • Waveforms (sine / triangle / saw / square) plus an acid filter • Delay, reverb, Glitch, Granular, overdrive • DRIFT / FLUTTER — tape movement on the synth voices and the live input alike • Concert pitch A=415–444 Hz ■ Connect • AUv3 plug-in — as an instrument and as an effect • Ableton Link, MIDI Clock, MIDI out • External audio input (line / microphone) • WAV recording and export One-time purchase.
