To Bob's extreme disappointment we weren't allowed to touch the pianos. We could hear a recorded performance of it though.
A rare electroacoustic piano! Pickups amplify the strings.
This piano was owned and played by Franz Liszt. The strings are hit from above.
A very large accordion. Full sized accordions have 120 buttons on the bass. This one has 280. Bob's mouth was watering; Carla's ears were bleeding.
The Orchestron is capable of 128 voice polyphony, with independent channels for cymbal, drum, and triangle.
