[>]  Hi Roger,
The other modes are not fine... in Unison, you just can´t tell the
misbehaving voice from the 7 others, and in Poly 2 or Solo you are probably
not activating that buggy voice. 
The problem is very likely a tuning/calibration issue. Its quite hard for
one to give such advice without actually *hearing* what´s going on. I would
try to get a service manual and run the calibration procedures, but if you
are not quite used to calibrate such machines, the Jupiter is a bad place to
learn.... its a complex machine! Did you ever took a look inside the Jupiter
8?? It´s amazing!!

Good luck!
