website = US patent|5315057iMUSE (Interactive MUsic Streaming Engine) is a
game engine developed in the early 1990s by composersMichael Land andPeter McConnell while working atLucasArts . The idea behind iMUSE is to synchronize music with the visual action in avideo game so that the audio continuously matches the on-screen events and transitions from one musical theme to another are done seamlessly. The iMUSE system ispatent ed under US patent|5315057 by LucasArts, and was added to the fifth version of theSCUMM game engine in1991 .iMUSE was developed out of Michael Land's frustration for the audio system used by LucasArts while composing "
The Secret of Monkey Island ". His goal was to create a system which would enable the composer to set the mood via music according to the events of the game. The project was much more daring than he had imagined. He then brought in an old friend,Peter McConnell to collaborate on creating the system which they later patented together. The first game to use the iMUSE system was "" and it has been used in allLucasArts adventure games since. It has also been used for some non-adventure LucasArts titles, including the entireX-Wing computer game series (excluding and the windows ports of and ).Occurrences
A typical example of iMUSE at work is heard in the
cemetery scene in "Monkey Island 2": creepy music is heard while the protagonist is standing outside the cemetery gates. When he enters, the music subtly cross-fades to a variation of the same theme, picking up from the point in the melody where the previous one left. The same kind of transition is heard again once the character zooms in on acoffin . A slightly different use of iMUSE is present in the swamp scene, where the music starts out with a simple flute melody but as the protagonist proceeds deeper into the swamp, new instruments are gradually introduced to join the flute.Yet another good example of the iMUSE system is at the very beginning of Monkey Island 2 where Guybrush finds himself in Woodtick, the small harbor on Scabb Island. Whenever Guybrush walks into a boat, a new variation of the Woodtick theme plays. The beauty of iMUSE is evident when Guybrush then walks out again - the music smoothly fades out to the basic theme. Even if Guybrush walks out in the middle of a melody, iMUSE finds a way to end the melody quickly and then proceeds going into the basic theme again.
In the space combat title "", the iMUSE engine mixes the soundtrack based on the mission events in real-time from themes loosely based on
John Williams ' scores for the Star Wars movies. When a mission starts, for instance, a tranquil stand-by theme is often heard. If a Rebellion craft enters the area, this theme is interrupted for a brief Rebellion theme. Likewise, when Imperial crafts enter, the first cue ofThe Imperial March is heard and at this point, with imminent combat, more fast-paced themes are introduced.In "
Sam & Max Hit the Road ", entering Sam's DeSoto parked at the outside the pair's office triggers a transition to a faster melody as the car speeds off. This is an example of iMUSE's ability to form a smooth bridge between two dissimilar pieces at an arbitrary point in time.See also
