   • Repeat
     Tells Musical Scales to keep playing the selected scales.
     
     
   • Use C Key
     Tells Musical Scales to display the key signature in the key of C. When this check box is not checked Musical Scales tries to find the best key signature that fits the scale.
     
     
   • Base Clef
     Tells Musical Scales to display the notes in the Bass Clef. Notes are displayed in the Treble Clef when this check box is not checked.
     
     
   • Metronome
     Tells Musical Scales to play 4 notes before each scale to prepare you for the tempo. This is useful if you are playing along or singing along with the scale.
     
     
   • Add Delay
     Tells Musical Scales to delay starting the scale for 4 beats. This is useful when you want to play along with an instrument. It will take a few seconds to prepare your hands to play after you press the start button, so if you check the Add Delay check box, Musical Scales will give you a few beat counts so you can get ready to play. Unchecking Add Delay will also cause the Metronome check box to be unchecked.
