It looks like a little kids keyboard in 2nd grade music class. Its not. This project ranges all 128 General MIDI instruments! And you can turn flats on and off. Press the green flag to start, then rock away. The "flat 7th" button makes the "B" sprite into "Bb" or whatever its transposed to. The "flat third and sixth" buton turns the "E" and "A" sprites into "Eb" and "Ab". To play a basic chord progression: Play C-E-G-C. Set flat third and fifth to on. (If playing a 6m7 chord, make sure to turn flat 7th on.) Transpose down to -3. Play C-E-G-C (Or C-E-G-B for 6m7 chords.) Set flats to off (key to major) Transpose down to -7. Play C-E-G-C. Transpose up to -5. Set flat 7th to on. Play C-E-G-B Turn transpose to 0. Turn flats off. Play C-E-G-C. Congratulations.
