Once it is in YEM, you can send it to your keyboard, generate an install file (PPI format), copy voices to your own custom pack and even edit the voices themselves. The PPF file must first be loaded into YEM. The expansion pack is in YEM project file format, sometimes called a “PPF file” because of its file extension. I’ve done as much testing as I can in YEM. (I’m happy with the S950, thanks.) In response to requests, however, I have produced a new YEM-compatible expansion pack. Why “alpha test?” At this time, I do not have access to a YEM-compatible workstation in order to do my own testing. The list of YEM-compatible arrangers include the Tyros5, PSR-S670, PSR-S770 and PSR-S970 workstations. That’s all changed! I’m pleased to announce the alpha test version of the Jazz Scat voices expansion pack for YEM-compatible Yamaha arranger workstations. Up to now, Tyros5 users have not been able to load and use the original Jazz Scat voices expansion pack.

The new approach to expansion pack development and use is embodied in the Yamaha Expansion Manager, or “YEM” for short. With the Tyros5, Yamaha took a different direction and format for expansion packs. The original Jazz Scat voices expansion pack for the Yamaha PSR-S950 arranger workstation remains a popular part of the site.
