Moving down again brings you to the Chord Type buttons. Acoustic players might prefer to opt for open chords, while electric git-fiddlers will likely want power chords to be shown.
The last control is used to switch between four different neck types for displaying your chord patterns. The default is no neck type, then there's what looks like rosewood, followed by lacquered maple, and natural maple. The box on the right is home to a Chord Finder. Selecting the chord name from the two boxes at the top results in the appropriate chord shape graphic appearing below (though this does appear to be limited to open chords only). A useful extension would be to allow users access to the neck diagram, to click on the strings where fingers need to be placed and be presented with the appropriate chord name. The bottom part of Riffstation is given over to playback control, with a metronome dial on the left to increase or decrease the presence of a timing click in the mix, and an overall volume knob on the right.
