Chord Progression MIDI Effect

Windows install help

Windows may ask before running a new installer.

ISOREK installers are signed, but Microsoft Defender SmartScreen can still show a warning while a new publisher and Azure-signed certificate build reputation in Microsoft's systems.

The installer is still protected by code signing. The warning mostly means ISOREK is new in the software market.

Prologue helps you create and use chord progressions in your music. It is meant to be the first thing you open when you start a new project: sketch the harmony quickly, then send it to different instruments and timbres. Use mood presets, chord symbols, timeline edits, JSON import, or AI-assisted prompts to move fast. Prologue makes extended chords easier to write, voice, and reuse, with Bass, Body, and optional Shimmer MIDI lanes for building parts from the same progression.

• ✦ Start a new project with harmony in place before you commit to sounds
• ✦ Create progressions from mood presets, chord-symbol text, timeline edits, JSON import, or AI-assisted prompts
• ✦ Send one progression to Bass, Body, and optional Shimmer lanes for different timbres
• ✦ Work with extended chords without manually programming every note
• ✦ Build song sections with independent progressions, progression lock, and local project save/load/delete
• ✦ Export full progressions, single chords, or individual arrangement layers as MIDI
