I have a Juno-G (another Roland) that recently acquired the dreaded LCD screen death. Luckily I can still control all functions from the computer (via USB) once the Juno-G boots, so it's still servicable until I get it to the repair shop (covered under warranty once I find the receipt).. actually I can do some things much easier from the computer, now that I've started using it that way; the attached memory cards seem much more flexible now.
Anyway, I know what you mean by "if I had to give all but ONE HW synth I'd keep the ..." comment. I'll probably use the computer to control the Juno-G for a while before giving it up for repair. I'll miss it (let alone the hassle of driving down to Detroit to drop it off and pick it up a few weeks later).
Maybe I can just tell the wife it died and I need a new synth.

Thanks for donating the patchmap!
