# The Heads-Up Display

Capo's speed and pitch controls are accessible in the Heads-Up Display (or, HUD for short) at the bottom-left of Capo's main window.

When the speed or pitch of a song has been modified in Capo, the small dot or 'light' next to the word SPEED or PITCH will light up as it indicates the value is "dirty", or "not true."

For example, when the light beside the SPEED button is lit, the speed setting is not at the "true" value of 1x. Similarly, when the light beside PITCH is lit, the pitch adjustment is not zero, and the song is not playing at its "true" pitch.

In the screenshot above, you know the SPEED is not true, because the SPEED light is lit (and the slider is obviously not at 0), but you know that the song is playing at its normal pitch, because the PITCH light is not lit.

These two small lights are very handy in Capo because you can tell at a glance whether the song playing is in its true speed or pitch. When you load a Capo document, and you want to resume learning a song for which you modified the pitch, you will know right away if the speed or pitch has been adjusting just by looking at the indicator lights.

Both the speed and pitch of a song can be adjusted using either the menu, your mouse, or your keyboard.
