See the classic ADSR (Attack, Decay, Sustain, Release) curve. Click and drag the nodes. You can make a piano punchy or a pad swell over 20 seconds.
The trial version cripples loop functionality. The full version gives you precise loop start/end points, crossfade looping (eliminating clicks), and sustain loop mapping – critical for pads, strings, and any held note.

Yamaha voices are built from up to 8 or 16 Elements (oscillators). The Editor lets you:
Pirated versions exist but carry risks: malware, incomplete features, keyboard incompatibility, and no technical support. Yamaha actively discourages their use.
It is crucial to distinguish this tool from the Yamaha Expansion Manager. The Manager is used to install official Yamaha voice packs (like the "Euro Dance" or "Oriental" packs). The Expansion Voice Editor is for creating those packs.
Think of it as a hybrid between a sample editor and a synth programmer. The software allows you to:
