What is the right order for tuning the strings?

If you are tuning a guitar, by default Roadie starts tuning the lowest note first. Place Roadie's peg connector on your instrument’s tuning peg starting with the lowest pitch note first. The string corresponding to the lowest note is the top string in the case of guitars, which is also the thickest string.

When the first string is in tune, Roadie will give you multiple cues to move on to the next string: it will beep, flash the indicator LED green, vibrate and display the next string on the screen.
