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)
