I have a list of frequency numbers and onsets coming out of Bach, in the following format:

The full list is 100 elements including parentheses.

I have made a list of gradually increasing onsets (so instead of 500, we get 100, 200, 300, and so on).

I would like to substitute every third element of the list with the list on the right hand side of the patch (so the first two instances of 500 become 130, 195, and so on).

I'm really terrible at list processing these days, please help!
