When in Motif mode, as you press the Next Motif button, the lights will blink back a color. This is to help identify what section of the Motif menu you’re in. The pattern sequence starts at the beginning of the spectrum at the color red and loops around the color spectrum.
This helps you to identify a specific pattern’s location in the sequence. You can press Next Motif quickly until you see the color associated with the part of the sequence you’re looking for, then more slowly advance to the particular pattern you want. You can use the Stop Back button to navigate backwards in the sequence.
