It comes with 10 Voice Banks and 66 Styles, so each virtual vocalist has a few variations, in which he or she can perform. These Banks and Styles are named to help identify and specify vocal character.

All Styles can be used in Solo, Dual or Poly mode, which increases possibilities for the user.
Another great VM1 feature is automatic phrasing and breathin. VM1 has phrase Volume and Pitch envelopes and inserts noises in pauses, which animates the voices considerably.

VM1 has an advanced system of patch parameters: every VM1 Style is a set of 7 patches, and their parameters are used for calculating the current patch on the base of musical context: Velocities, Note Numbers and music Intervals. Due to the morphing of patch parameters" the sound very sensitive to musician's play or to a MIDI score. Phrasing and insertion of noises add sufficient liveliness of the sampled synthesis. We call this approach "Context Dependent Expressive Synthesis.

The interface is very simple, so musicians are freed from technical details, and have wide possibilities for manipulating the sound.
