Here's a score I prepared for a user the other day, an excerpt from one already published on CPDL. I'm not fond of the Mensurstrich notation myself, but I'm posting the score here in case anyone else finds it useful too.
For anyone wondering, this is the 2nd part of Magnus es tu Domine transposed a minor third higher. The piece is variously attributed to Finck or Hellinck but appears to be accepted by the Stanford Josquin Research Project.
