Ensemble Voice is an amazing new feature that reproduces true "divisi" playing in a section. In the past, a Voice like Brass Quartet would use a sample of four players, which sounded great. However, if you played two notes you'd get eight players, which could sound great but isn't the most realistic. Tyros5 Ensemble Voices always get the same number of players because Tyros5 has the musical knowledge of a professional music arranger. Play two notes with a Brass Quartet Ensemble Voice, and Tyros5 will send the trumpets to the top notes and the trombones to the lower notes; it's an incredibly realistic sound.Ensemble Voices also utilize parameters which enliven the performance to reproduce the subtle variations in timing heard in a real ensemble. This provides an authentic sound that sounds as if a group of actual performers were playing and allows you to enjoy playing like an instrumental quartet with ease.
