This PSR-E273 website is not Yamaha approved. Nor does Yamaha, or any of its known affiliates, have any influence on what goes on here. Since most of what is contained in the official PSR-E273 manual is misleading, misguided, harmful to the creativity of the keyboard's user or just plain out and out wrong.
Thus, the intent is to go far beyond the mere use and maintenance of Yamaha's legendary PSR-E273 61-key keyboard. Because the PSR-E273 as a learning instrument has virtually no boundaries.
