hi diki...
i just tried holding it...nada...
the switches i have are all damper pedal units for keyboards.
and i have one that switches polarity...
i tried that one in both polarity positions...nada.
all 3 of these damper pedals work fine with the keyboards...
so i know they are not broken.
thanks for the responses...
i'll look at the TC site and look into the different types of switches that are available. The manual doesn't specify much.
