Abstract:

In this session a Yamaha Disklavier Grand Piano computer based performance reproduction system will be demonstrated. The instrument incorporates optical sensing devices which monitor onset of key motion and hammer velocity. This information is recorded and then used to drive electromagnetic plungers to activate the piano keys in a dynamic performance reproduction on the original instrument. Computer control permits editing as well as transposition and other technical modifications. The computer connection also enables the use of the instrument as a MIDI input or output device. The demonstration will include reproduction of a number of performance examples by noted artists. The demonstration will take approximately 25 minutes. It will be repeated on Wednesday at 8:30 A.M. The instrument will also be available, by arrangement, for small group hands-on evaluations.
