MM stands for “mini-mo”. It means the sound setup of the Yamaha MM8 is made based on the typical MOTIF XS series of Yamaha’s pro-level instruments.

The Yamaha MM8 sounds live and smooth. The Master EQ and a variety of other quality effects generate these real sounds. Unlike other models, these sounds are categorized for easy searching.
