Pattern Mutator Free

Changelog

A concise public record of improvements and fixes for the free, local-first MIDI idea generator.

  1. Current release

    v0.5.0

    Keep your musical idea intact while developing and exporting it.

    • Mutation now develops the current notes with a dedicated amount control. At 0%, the pattern stays unchanged.
    • Prevent mutation timing collisions and use the same repeated-note articulation in the piano roll, playback, and MIDI export.
    • Automatically recover the current draft, harmony, locks, editor settings, and undo/redo history after reloading.
    • Regenerate a bar within its stored harmonic progression while preserving neighboring bars and locked values.
    • Keep the pitch viewport inside the selected register, including after deleting every note.

  2. v0.4.0

    A more reliable composition workflow, now named Pattern Mutator Free.

    • Mutation locks preserve the original notes without dropping or duplicating locked values, including during bar regeneration.
    • Keep every generated pitch inside the selected scale and register.
    • Export tempo, 4/4 time signature, and the full selected bar length in MIDI files.
    • Navigate and edit all 32 bars, with full-length audition and a playhead that follows the visible bars.
    • Add pitch labels, bar numbers, live note movement and resize feedback, and a more compact mobile layout.
    • Build patterns around a consistent chord progression, repeated motifs, and controlled phrase endings.
    • Restore a pattern's musical settings with undo and redo.

  3. v0.3.0

    Expanded the free composition workflow with faster direction, editing, and auditioning.

    • Added five Quick Starters and a Low, Mid, or High register control.
    • Added undo, redo, and reset controls for piano-roll editing.
    • Added selectable audition sounds, a moving playhead, and loop playback.
    • Added selected-bar regeneration, keeping every other bar in the pattern intact.

  4. v0.2.2

    Added free Rhythm Feel controls for quicker musical direction.

    • Generate straight, syncopated, half-time, driving, and sparse patterns.
    • Include the selected feel in the current-pattern summary and Surprise Me results.

  5. v0.2.1

    Renamed the free browser tool to Pattern Mutator Lite.

    • Clarified that this is the focused, single-pattern MIDI workflow.
    • Kept every existing tool and changelog URL unchanged for bookmarked links.

  6. v0.2.0

    Added a basic free piano roll so generated ideas can be finished before export.

    • Click an empty grid cell to add a scale-safe MIDI note.
    • Drag notes to move them, resize from the right edge, adjust selected velocity, and delete selected notes.
    • Kept direct editing and single-clip MIDI export free.

  7. v0.1.1

    Added a dedicated public changelog directly from the Pattern Mutator Lite footer.

    • Made the current version and release history easy to find from the tool.
    • Added a searchable changelog route for future feature notes and fixes.

  8. v0.1.0

    First public draft of Pattern Mutator Lite.

    • Generated scale-aware melodies, basslines, chord patterns, and arpeggios.
    • Added 1–32 bar pattern lengths, controlled mutation locks, browser audition, and Standard MIDI export.
    • Kept generation and export entirely local in the browser.
