Touch-Sensitive Organ Based on an Electrostatic Coupling Device
Hugh Le Caine · The Journal of the Acoustical Society of America · 1955
A device for coupling generators to sound systems in electric musical instruments is described, particularly in connection with its use in a touch-sensitive keyboard. The construction of such a keyboard is shown to be quite straightforward. Many well-known types of generators and any timbre control system may be used. The musical value of a touch-sensitive action is difficult to assess, but the writer is impressed favorably.
