Just wanted to post voice programming information for two example Genos Live! voices. "Live" in Yamaha-speak means "These acoustic instrument sounds were sampled in stereo, to produce a truly authentic, rich sound -- full of atmosphere and ambience."
SeattleSpiccato has three elements and each element has its own stereo waveform. An incoming MIDI note triggers one or more elements according to its MIDI note number and velocity. In this voice, element #2 is always triggered since it is spread across the entire note range [C-2:G8] and velocity range [1:127]. Element 0 is triggered if the incoming velocity is in the range [1:89]. Element 1 is triggered if the incoming velocity is in the range [90:127].
So, a MIDI note always triggers two elements -- that's two "voices of polyphony." Since Genos (SWP70) elements are stereo and the waveforms are stereo, it's only two "voices of polyphony."

Allegro is an old legacy voice which is a layer of two stereo instruments. It's waveforms are mono. Elements 0 and 1 are a pair and are panned hard left (-1) and right (1). Elements 2 and 3 are a pair and are panned hard left and right.
An incoming MIDI note triggers all four elements because all elements are spread across the entire keyboard [C-2:G8] and the full velocity range [1:127]. The Allegro voice consumes four "voices of polyphony" for each MIDI note! Genos still has a lot of these old legacy voices.
Hope these examples help out. The discussion can get pretty abstract. :-)
All the best -- pj
