Wouldn't putting a diode in series with the input block a negative voltage??

I think a relay might be too slow.

Speaking of slow, I tried thinking about this last night and nothing
happened.  Then when I woke up this morning I had an idea that maybe
someone could test:


1)  Switch the 820 on (Bypass off)
2)  Take a CV output (not a gate or trigger) from a Kenton converter
    and plug it into the 820 Bypass jack.
3)  Send it 0, what does the LED do??
4)  Send it +5V (127), what does the LED do??


I think that it should work the way I want without modifying the 820 at all.
