I acquired a DGX-640 for one of my optional classes that introduce computer-aided design and micro-fabrication principles to educational technologists. The course goals include learning some technology (computerized embroidery, 3D printing and music education technology. Then, we also address a variety of educational issues related to design with computers, learning with computers and computer-controlled devices and learning through computers.

This page summarizes a few features of this piano and should at some point include information of interest to educators.

After a few minutes of exploring the instrument, we believe it to be a good buy in that price category (800 CHF). More later. - Daniel K. Schneider 15:27, 1 October 2011 (CEST). The reason we acquired this piano is to explore how people could learn about music and piano playing using its various assistive technologies.
