I think most of the reproduction systems right now are using the solenoid idea. Yes indeed the solenoid is playing the key from the back, in a similar fashion to a finger pushing down on it in the front. This type of operation means that you can have a reproduction system without anything really interfering with the piano action itself. This makes it useable as both a "serious" instrument, and also as a "party favor" =OÞ Jonathan Finger RPT -----Original Message----- From: pianotech-bounces@ptg.org [mailto:pianotech-bounces@ptg.org] On Behalf Of Isaac OLEG Sent: Thursday, January 23, 2003 11:42 PM To: Pianotech Subject: RE: Key Leveling System Are the reproducers elements them solenoids , and do they play the keys from under the action ?
