The unit had casters and rolled up to the keyboard. It operated from a cassette tape to activate push rods covered with felt. A few adjustments for height and a clamp under the keybed to hold the unit in place and you had instant piano playing. While there were many students around to do play-in their session usually lasted only a few hours a day. I was satisfied with the vorsetzer. Perhaps there are some of these machines languishing in someone's basement waiting for a garage sale. A few ads may be more productive than building one from scratch. Or, just tune the piano twice a day for a month. Joel -- Joel A.
