Huh! sounds exactly like the keyboard implementation of my Jupiter 4.
I've got a feeling that many if not all of those functions are on a
separate board in my JP-4 as well, so perhaps they used the 184 design
to drive the JP-4, or vice versa.

The mod, by the way, for tapping into a JP-4 to either extract or insert
pitch CVs and Gates appears to be ridiculously simple. I think I posted
a link to the page before--

No, I've not done that to my JP-4, as I was happily able to scarf up an
MPU-101 recently. Now all I need is that -440 filter and second -300
osc. Er, and many other things too....
