This feature will play MIDI, so make sure that your MIDI Setup is working. To test this, within Band-in-a-Box, go to the Pianos tab in the top right (don't see it? Hit CTRL T to see the full BB screen)

Click on any of the pianos and you should hear something - if you don't, go to Options | MIDI/Audio Drivers setup and check your MIDI Output - if you do not have any output selected, you won't hear the Chord Builder (this happened to me too).

If you are using ASIO instead of MME, the important thing is to have ASIO Always On checked. If the driver wasn't selected, you wouldn't have sound at all, but if that box is unchecked, you would only have sound if the song is playing, so MIDI Thru would stop working as soon as you stop playback (added with Edit - thanks Kent!)

To change the instrument, within the Mixer, go to Patches and change the instrument for the "Thru" channel. If you do not see "Thru", you will have to click on the [THRU+] button (lower right of the mixer).

If the problem continues, please let us know!
