I have located one just recently discussed on the RolandClan forums. It's for Cakewalk, but PowerTracks is able to convert it to its INI format. However, there are too many patches in it (>2000) for my version of PTPA (2012). You can download the original Cakewalk version at http://www.jp-80.com/fa/fa.html. It's not an official version, so the usual caveats apply.

Does anyone know if newer versions of PTPA allow more patches than 2000?
