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 replaces note-by-note chord programming with a hands-on harmony workflow. Sketch progressions quickly, then send them 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
