I meant that the FB LEDS did strange stuff during record.

FB LED comes on green much quicker than the Inp.
..but FB LED doesn't go Red on Record ever.

Hope that puts your mind at rest:-)

Also if you Record a silent loop, and then go into Overdub the Feedback 
LED will light during sound input.

I reckon Matthias wanted to see the overload in the loop as he was putting 
on a new layer to the loop, then he could undo and the distortion could be 
erased, but that's pure guesswork on my part. 
Maybe it's just that place where the signal for the LED is taken on the 
circuit gets the input to the loop, which is the FB plus the edp input.

Matthias or Kim could probably say exactly what's going on here.

As both LEDS do what they're supposed to, and this seems to be a normal 
part of EDP operation you certainly don't want to send your edp away for 
this. 

The difference in response makes sense, the 2 LEDS perform different 
functions.
