[Harp-L] RE: TurboHarp develpment bench - ELX

For the multiple channel ouput flavor of the ELX might this optical
method of sensing the reed vibration partially eliminate the need for
valves on the chromatic harp?

Valves might not be needed at all in a chromatic ELX harp if there was
one channel of output per reed.
