MOTM

Although this sounds like a cool idea, I don't know if the unit would
work in the manner you describe it. The CV monitor used a 1/4" plug, a
resistor and an LED. It works because a voltage there is voltage present
at the jack to power the LED. If you were to remove the resistor and
replace the LED with a photocell I don't think the photocell would
generate voltage to control an module. If I recall correctly, a
photocell acts a variable resistor, in order for this circuit to work
you would need a source voltage for it to do anything. I wonder if a
solar cell would produce the effect you are looking for? It would be
very interesting under stage lighting since a solar cell responds
differently to varying intensities and colors of lights. You'd probably
have to deal with a portamento effect on the response though figuring
the FM controls on the modules don't draw enough current to drain the
cell instantly. -Nate ( the other one)
