I recently purchased a MOTIF XF with the intention to upgrade the piano patches using the 1gb and 512 mb flash cards that came with it. I know that most piano sample libraries for the unit are "old" they were released some 7-10 years ago, still I believe it should be possible to make the MOTIF sound fairly up to date as far as pianos are concerned. Is there a sample library that you would recommend for live performances? I typically play with smaller jazz ensembles and a good Yamaha or Steinway D grand piano sample set is probably what I am looking for.
