Cooking your delays?

[Andreas Wetterberg <awetterberg@post.cybercity.dk>]

I like leaving my tape delays, pedals, delay  and looping plugins 
running for a long time, for instance while I'm having dinner and 
whatnot. When I return, there's often distorted loveliness waiting for 
me in the cans.

Do you do that as well? Any tips?

Andreas.
