What is a MUI file?
An MUI file is a user instrument file used by Myriad musical notation software products such as Harmony Assistant. It stores sounds for a variety of instruments such as piano, strings, woodwinds, brass. MUI files are used for generating realistic sounds.
There are many default instruments that come with Harmony Assistant. The instruments consist of a recording of an instrument playing a specific note and parameters to tell the program how it should be played. The MUI file allows users to create instruments other than the default ones by editing an instrument and selecting "Save predefined instrument" in the "Action" contextual menu. The user can also define the parameters of the instruments such as the note range, sound attack rate, decay, volume release, and loop release.
