I think this mod might help me quite a bit, especially if I can get it to 
synch
only on the "beat 1" red LED flashes and not the "beat 2,3 &4" green LED
flashes. I pretty much always record the long loop over some integer 
number of
repetitions of the red LED flashes.

When you did this, did the EDP respond to both red and green flashes or 
just red
flashes? If it responds to both, it might be possible to get it to respond 
only
to the red ones by putting a diode in series with it, right? If this is a 
two
color LED whose color is determined by the direction of the current.

I have some loops that are in 3/4, 5/4 and 7/4, and for these, the red 
LED's
line up with beat 1, but the green ones are in the wrong place. So I would 
be
better off with red-only.

I wonder if you could "OR" two RC-20s' synch signals together by mixing 
them
with a resistance mixer. If I did that then I could use prerecorded loops 
from
either RC-20 and still get synch.

Very cool idea!
