I want to generate a midi track then play in the web audio. But I don't know how to change the instrument or sound type with the current web site instructions. Very thankful hope.

Hi! Thanks for asking!
There is a special midi message that changes the instrument/sound.
See https://jazz-soft.net/doc/JZZ/jzzmidi.html#program
