In order to make sure Harmony Improvisator works in your music production setting we offer a free demo version of the plugin for Windows and Intel Mac. The version's functionality is limited in that

• The main key cannot be changed, but instead is fixed to Db
• Harmonic patterns cannot be saved, neither as MIDI file nor in the Harmony Improvisator specific HARM format
• Chord progressions cannot be loaded
• The plugin only sends out one of the four chord voices as MIDI data
