Control device and keyboard instrument

A control device comprising:

• a first transmission unit configured to transmit first performance data including contents of playing a first keyboard instrument at a first communication base to a second communication base;
• a first receiving unit configured to receive second performance data from the second communication base;
• and
• a first generation unit configured to generate a first drive signal and a second drive signal to produce sounds in accordance with the second performance data and output the first drive signal and the second drive signal to a sound generation device at the first communication base,
• wherein the second performance data includes a first measurement signal and a second measurement signal indicating a vibration of a soundboard of a second keyboard instrument at the second communication base, and
• wherein the first generation unit is configured to reduce crosstalk components in the first measurement signal and the second measurement signal, respectively, to generate the first drive signal and the second drive signal.

A keyboard instrument comprising:

• a key;
• a soundboard;
• the control device, the control device comprising:
• a first transmission unit configured to transmit first performance data including contents of playing a keyboard instrument at a first communication base to a second communication base;
• a first receiving unit configured to second performance data from the second communication base;
• and
• a first generation unit configured to a drive signal to produce a sound in accordance with the second performance data and output the drive signal to a sound generation device at the first communication base,
• wherein at least one of the first performance data and the second performance data includes a key position signal indicating a key press amount on the keyboard instrument;
• and
• a sound generation device generating a sound based on the drive signal at the first communication base,
• wherein the sound generation device includes a vibration exciter connected to a speaker or the soundboard, and
• wherein the drive signal includes a first drive signal for driving the key to reproduce the key press amount in accordance with the key position signal.
