What is the main purpose of the 'mix' function in EarSketch?

The mix function in EarSketch is primarily designed to control the volume levels of different tracks. This functionality is essential in music production because it allows for the balancing of sound across various elements of a composition. By adjusting volume levels, you can ensure that each instrument or audio sample is heard clearly and contributes effectively to the overall sound. This promotes a harmonious blend of different sounds, enabling the music to be both dynamic and cohesive.

Options relating to recording audio samples, arranging tracks, or adding effects like reverb serve different purposes in music production. Each of these functions plays a vital role in the creation of a track, but none are specific to the primary function of mixing, which is to adjust volume levels for optimal sound quality and balance.
