In fact you can just look at the snippet at
https://lsr.di.unimi.it/LSR/Item?id=848 I've set mine up slightly differently, with letters between the lines, but the principle is the same. But as you see from this snippet, you have to enter the notes and values for the tablature stave, and the note durations again (with appropriate "silent" notes) for the rhythm stave. And both these staves have to be created independently and put together at the end.
I want to know if you can do this without having to enter the rhythm durations and stave separately - the information in "myNotes" in the snippet contains all the information needed. I'm hoping for a solution where all you need to enter is "myNotes", and then both the tablature staff and the rhythm staff would be created in one go.
Thank you again.
