iMUSE (Interactive MUsic Streaming Engine) is an interactive music system (responsible for smooth transitions between themes, triggered by player's actions) developed by Michael Land and Peter McConnell for LucasArts. Initially a MIDI sequencer, its later incarnations used digital audio formats.

While it's easy to name the titles from its MIDI days, I have problem deciding if the latter ones are still the same engine. Yet the credits claim so. Another problem are the games with little-to-none music interactivity. RolaPL (talk) 03:40, March 4, 2013 (UTC)
