Michael,
I tried my SDX with standard piezo pads and all (ZI) channels work no
problem. I think the spec for the ZI input was something like +5v or -
15v (one was for position, other for intensity but I can't remember
which way round). Doesn't seem to have harmed my SDX either !
Phil.
PS welcome back Patrice :o)
