I entered this contest where you could download a file of Yo-Yo Ma playing and add a part to it. The link will take you to my entry. I recorded it in Reaper, of course, using an OktavaMod MK012 through Firestudio 26x26. I used a crosstuned mandola to complement the low voice of the cello. Check it out.
