After setting the time signature to 3/4, I entered a G chord into bar 238 and a D chord into bar 245. I didn't enter any other chords anywhere else. Then I selected "Select and generate a RealTrack" from the menu and picked #856 (12 string acoustic guitar). When RB was finished generating the track, I clicked on bar 235 in the Chords window and clicked on the Play button. I could definitely hear a chord change at bar 241---most likely to the C chord.
