Inside the Expansion Manager:

Yamaha Expansion Manager (YEM) is the official tool for creating and managing custom expansion packs for Yamaha arranger keyboards, synthesizers, and digital workstations (e.g., PSR-SX series, Genos, Montage, MODX).

After installing the pack to your keyboard, manually assign VCM (Virtual Circuitry Modeling) effects to your custom voices. This Yamaha proprietary technology raises the perceived quality to near “extra quality” standards.

The "Export to Instrument" function is the core utility. In v2.8.1, the file verification process is more rigorous.
