Low triangle voice!!

[Steven Maietta]

I just got a Yamaha CS-01(all analog) and it is really cool except for the
fact that the triangle voice is at a really low level compared to the rest
of the wave shapes.  I know that this isn't right, so are there any ideas
concerning this that come to mind quickly?  I'm gonna open it up and snoop
around, but I thought I would let you all give it a go with suggestions.
Thanks!!
