This 4 x 8 deck controls parameters in the Batch Fade window. I have mine set to avtivate when the Batch Fades window is open.
The left hand buttons are set to some common presets. Beware, when making your own, that some fade shapes are not available when Equal Power is selected. The last template option "Select Fade Length" will selected the length field you expect to type in.
The right hand buttons cycle through fade options.
