I appreciate the different added nuance effects the SA2 button triggered buttons provide, but over my 4 hour afternoon time auditioning and playing Tyros3 live running thru & playing thru my song repetoire of many styles/genres, I felt I was able to achieve indivual instrumental nuances I needed by simply playing the SA2 voices alone (triggering unique instrument emulation via kb velocity & playing techique alone), without regard to the buttons. That to me is the amazing feature of playing SA voices. For live playing, I feel the SA2 buttons an optional thing, as I would probably reserve their use for critical studio work & recording, but that's just me.
