A CSV file is supposed to be a matrix with the columns presenting a vector. Each row mustr be on a line, with numbers separated by spaces. A dialog is presented with the columns found and you may select the vectors you need. A vector is one-dimensional. Keep in mind that you assemble the pitch and duration aspects on the clip. Do not try to create a vector from CSV with more than one dimension.
As a matter of fact I am overhauling the CSV aspect of Compose! by request of another user. If you let me know eactly what you want I might accomodate you. The version I am working with has CSV made easier. It has been somewhat tested. I might release this version if you think you need it.

I am not sure I understand this. Could you describe exactly what you did and *what* you were trying to accomplish?

You are very welcome
