You probably have a blown ADSR generator chip. It's a custom Roland
To be sure if this chip is really fried, you'll have to measure the
voltage in its output pin, and check if it's acting as expected (0 to +10v,
according to the envelope shape). If it´s OK, you´ll have to follow the
signal path until find out what´s wrong. I think it´s only possible with
schems at hand... you know, Jupiters are complex machines.
