Typically, 3rd parties (or Yamaha) will also release a promo pack which includes older samples no longer available. This is where, for example, Inspiration In A Flash helped bridge the gap as well (original Motif piano samples).

Has anyone succeeded in moving all the way through this process and converted ES voice to Montage performances? I would be very interested--there were several amazing voices I used in a film score back then, and I would love to see if they can live on in the Montage for a current project. Thanks!
