DL4 questions

[PMimlitsch@aol.com]

Can the Roland EV5 be used as the expression pedal or does the Line 6 ex. 
ped. have to be used?
Can 2 DL4s (or other) be run off a single power supply.  A while back 
someone 
on the list mentioned it was possible but I never got the full concensus 
of 
opinion as to whether it was safe for the machines or not. 
Is there an upgrade to the DL4.  I got one when they first came out and 
have 
heard hints about an upgrade to correct some problems in the first batch 
produced.  While I haven't experienced any "wierdness" from the one I've 
got 
I'll probably be adding another (or a Boomerang if I can ever find one) to 
a 
pedalboard/looping set up I'm working on and was just wondering if there 
would be a difference between the new and "old one.
Thanks - Paul
