Here are videos I think people here may appreciate. They feature the SoCal Keyboard Orchestra in Southern California, a group of older seniors performing together on Yamaha Tyros4 keyboards, and directed by Marco Mendez, featuring him on piano as well. The performance doesn’t utilize Tyros 4 auto accompaniment, but showcases the awesome Tyros 4 orchestral sounds.
And the link to one more that cannot be displayed here:
