Hi Tim and all,<br>
<br>
although this idea is inspired by circuit-bending, I was not planning
on following the usual Casio "poke and hope" method of circuit
exploration. Rather I am talking about taking a known modulation
bus which operates within a 0V to +5V range, and inserting a body
contact so that I can load down/mess with the shape of the signal it
carries. Perhaps connecting the body contact to the mod bus via a
100K resistor would suffice?<br>
