The Montage's sound library is built on the Yamaha's proprietary AWM2 (Advanced Waveform Memory) technology, which allows for the creation of incredibly detailed and nuanced sounds. The instrument comes with a vast range of built-in sounds, from stunning piano and string samples to cutting-edge electronic and synth sounds.

Sites like yamahamusicians are excellent for finding links to free user-made packs and discussing the legitimacy of third-party sellers.

Owners of Montage or MODX hardware can download premium libraries like Chick's Mark V and KA-Pro CS80 for free from the Yamaha MusicSoft store or the Yamaha USA download pages.
