Music Machine 17 is based on Bach's Prelude 2 from Book 1 of Forty-eight Preludes and Fugues.
It has four options for performance.
One shot - this will play all 38 bars of the original work once only but in a random order.
Looped - this will play any of the first 24 bars of the original work and will run indefinitely until stopped by the user.
One shot with ending - this will play the first 24 bars of the original work once only and finish with bars 25 - 38 from the original.
Original - this plays the piece as it was written.
