That weird mode switching circuit and the hybrid sub-circuit modules make the whole thing kind of confusing, at least the way it's drawn in the service manual. It doesn't help that the filter chips are just shown as black boxes, with no graphical depiction of internal functionality or pin function. I need to take the time sometime to draw it out in a more straightforward, logical, signal-flow depicting manner.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>I bought a brand new Jupiter 6 in 1982 because it was the only synth out of the ones I was looking at that had MIDI. Somehow, I sensed that the whole MIDI thing might be kind of important, although I wasn't quite sure why -- not yet, at least. It was a lot of money at the time -- more than $2000US -- and I was not rich, so it was a really big decision. The other contenders for me at the time were: OB-8, Prophet V, and Jupiter 8. Yes, yes, I know. I made the wrong choice. Mea culpa. I made up for it by replacing it with an MKS-80 Super Jupiter in 1984. I loved the MKS-80, but I missed the JP-6 bandpass and highpass filters, nevertheless. There's probably an Aesop Fable in there, somewhere.
