Xfade is shorthand for crossfading functionality (e.g., crossfading between two audio or control voltage signals). Crossfading is the process of gradually fading out one signal while simultaneously fading in another, resulting in a smooth transition between the two signals.
Xfade modules typically have two input jacks for the two signals to be crossfaded, a control voltage input jack, and an output jack for the crossfaded signal. The control voltage input is used to control the amount of crossfading between the two signals, allowing users to create smooth transitions or abrupt changes between the two signals.
