Modify number of measures per line
This is the second downloaded version (untouched by me), of the invention where I am trying to change the number of measures per staff without success. There is something that I am missing in the two explanation I received from Marc. Per his suggestion, I have downloaded the file of Bach's Invention #13. I would like to be able to increase or decrease the number of measures per line. I consider myself still a novice so I need fairly detailed instructions.
Thank you in advance.
