StepStrum Lite

Turn chords into natural strummed and chord-note patterns.

A free MIDI strumming plugin for turning held chords into realistic, tempo-synced MIDI patterns with upward and downward strums plus Low, Mid-Low, Mid-High, and High chord notes.

StepStrum Lite interface.

What StepStrum Lite lets you do

Sketch natural strummed and chord-note MIDI parts quickly, using chord-relative note selection and any instrument that responds to MIDI.

  • Turn chords into strummed MIDI

    Play a chord and hear a tempo-synced strummed pattern immediately.

  • Shape the strum

    Adjust timing, swing, gate, humanize, and velocity response from one place.

  • Build pattern slots

    Create and switch between up to eight rhythmic ideas.

  • Mix strums and chord notes

    Build patterns with Up and Down strums or select Low, Mid-Low, Mid-High, and High notes from the chord you are holding. The selected positions follow your harmony as you change chords.

  • Sketch faster

    Create guitar-style rhythm parts without drawing every MIDI note by hand.

Core controls

Nine controls let you shape how your strums feel, from timing and groove to velocity and retrigger behavior.

Spread
how wide the strum is in time
Gate
how long notes are held
Swing
groove and rhythmic feel
Humanize
natural timing variation
Velocity Mode
how dynamics are applied
Time Division
rhythmic grid resolution
Chord Window
how played notes form chords
Restart Mode
how patterns retrigger
Latch
sustain playback without holding notes

Upgrade to Pro

Lite includes all six playable step types. Pro adds MIDI pattern keyswitching and per-step velocity, gate, and trigger probability for $39 USD.

  • MIDI pattern keyswitching. Assign pattern slots to MIDI notes for real-time variations, fills, and changes.
  • Per-step velocity lane. Draw dynamics across the pattern one step at a time.
  • Per-step gate lane. Set how long each note holds, individually per step.
  • Per-step trigger probability lane. Control when each step fires to add natural variation.
  • Pro expansion packs. Use additional Pro content when available.
