Archive of the former Yahoo!Groups mailing list: All about the Roland Jupiter-series

Hi, recently I noticed that each time I switch on my jup8 it enters
automatically the self test routine (which otherwise needs to be
initialized pressing both swiches 1,2 and 3 during boot-up).
The problem is that after two complete cycles it stops on the 3d led
and keeps flashing it. When I play the instrument thereafter it
seems that sometimes - but certainly not all the time - and not on
all patches, a middle key (I think the B one in the middle of the
keyboard) will not sound or will sound with very low level. Can any
folk give me an idea of what is going on inside the beast? What this
3d led flashing is trying to tell me? Thanks for any help guys.
