Very basic - I have not experimented so as to obtain a pleasing sound. Note the axiom for the second voice is slightly longer this gives a difference between the scores for the two voices. the .abc notation version generated can be copied. For simplicity of the demo they share the same audio effects. The piano voice doesn’t much like reverb!! To see the sliders you need to scroll the player window. As with some other demos you can save the script or you can save a link with the script encoded ready to play when it is activated. Available on GitHub for developers.
