Re: multiple concurrent loops

[Chris Chovit <cho@newdream.net>]

You can only do this with one echoplex, if you layer the multiple loops on
top of each other.  The total loop length would have to be the lowest
common multiple of the individual loop lengths.  However, then you can't
use different feedback settings for the different loops.  Of course, this
is easy (and expensive!) with multiple Echoplexi.
