Just when you thought that Hendry was good for nothing but being a
stooge....

I have in my hands the service manual for the Juno 60 (6 with memory).
The key transpose switch is listed as follows:

Switch SUT11A-1 (13129321)  that is a momentary switch.
The colored button on top actually has a separate number:
016H036 gets you the white one (that's the color of my key transpose
button).

Now, concerning the original question, the DCOs are CPU controlled as it
looks to me.  However, the VCFs do appear to be actually voltage controlled
to me.  Looks like IC47 (14051B) is the VCF Demux.  I am not real sharp on
this stuff, but this thing is full of Mux and DeMux.  Most of the voltages
seem to available at those points (at least this is how the Juno 60 works. 
I think the Juno 6 is identical except it has no patch memory and has no
digital interface (DCB).

anyway, next xmas question: 
after spending an alarming portion (ie more than zero ;-)
of my time down the back of 19" racks, i came to another
interesting conclusion - it would be dead simple to hotwire
my Juno Six to send & recieve gate & CV information
anyone any hot tips before i spend \ufffd20 on a badly 
photocopied service manual..?

I wish I had some hot tips here! Many years ago a friend loaned
me her Juno 6, and I still have it, in fact i was just poking around
inside it a few days ago trying in vain to fix a broken switch 
(the KEY TRANSPOSE button). I didn't look at the feasibility
of CV outputs and I see why you might think it would be easy
(if the VCFs really are voltage controlled), but I'm wondering 
what you're thinking about given the polyphonic nature of the
keyboard. So please post to the list (or at least me) anything
you figure out regarding this -- and if your manual has the part
number for those Alps buttons, I'd really like to know since
that would make ordering a bit easier I'd hope.
