Bendometer Playing System is a harmonica software that used the microphone to teach you how to play bends, overblows, and even songs in harmonica tab format.
The first screen you should see is a simulated harmonica with notation. As soon as this comes up, you should be able to start playing your harmonica. As you do, you will see notes "light up". The upper row (above the numbers) represents blow notes, whereas, the rows below the numbers represent the draw notes (or notes you breath in).
If you have trouble seeing notes, first try holding the microphone to the harmonica while playing (or quite close to the harmonica). This will help get more accurate note detection in any case. If you aren't seeing any response, you might try changing mixers.
The notes are in standard musical notation. The picture above shows the notes in the key of 'C' as this is the harmonica pictured. You can also see this in the "Harp Type" dialog window.
When you load a tab file one of the notes will become highlighted. Simply play the highlighted notes to play the tune. When you have to play the same note twice or more, it will highlight in red.
