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.
