The Disklavier pianos they were using are built with optic sensors that record when a piano key or foot pedal is pressed and how fast they are moving up and down. The piano measures 1,024 levels of sensitivity for each key and 256 levels for each pedal, said Kirk Davis, a Yamaha Corp. district manager for higher education who attended the masterclass. The data from the piano being played is turned into code and sent to Yamaha’s main server in Japan, he said. Disklavier pianos connect to one another through the server, and the exact performance on one piano is reproduced on the other.
“I can hear exactly what’s coming out of the instrument. It provides more information than an audio recording because I can see it,” Sennet said.
