The VOICES parameter determines the number of simultaneous notes (also called polyphony) that are playable in a single Part. Omnisphere is capable of up to 64 voices of polyphony per part, and the VOICES selector determines the maximum number of voices that the Patch will have available.
The higher the number of voices that the Patch has, the more CPU power it will use, so this is a very important parameter in Omnisphere. The best approach is to set it only to the maximum number of notes that are needed for the given musical application.
The factory Patches have all been set conservatively, but if more polyphony is needed, you can increase the number of voices.
NOTE: Voices applies to all sounding notes, not just the ones that are currently being played. This is important to consider when playing sounds with longer release times. If you have let go of a note, but the tail is still sounding, it counts as a voice.
This function raises or lowers the overall pitch by transposing the Patch in 12-semitone (octave) increments. There is a total range of five Octaves.
Range -2 to +2 octaves
