not at all! It is one of the easiest things to do with the echoplex, but
also one of the most powerful and musically interesting. And what you are
doing with "dividing" the loop is often overlooked. That is also an
extremely useful technique. Thanks for the nice explanation.

Another very useful function of multiply is in combination with Record. If
you have multiply going, and press Record, the loop length will be
redefined at that point. So you could take a loop and cut out a shorter
chunk, making that the loop, by pressing Multiply and then Record before
you reach one loop time. Or you could make it longer by leaving multiply on
past one loop period (or more) and pressing Record, getting the whole loop
plus some arbitrary amount as the new loop.

Multiply-Record and Dividing are great when you work with long loops and
use feedback to evolve the loop. Letting feedback act on a long loop takes
forever, so you turn feedback down a bit and shorten the loop with multiply
or multiply-record. Then with overdub on you can quickly change the
character of the loop, and then turn feedback up again, and maybe multiply
it out into a longer loop again.

no, multiply in real time is unique to the echoplex. You could do it with
hard disk recording, but nowhere near as easily. Once you try, it seems so
completely natural and obvious. I don't think I could live without a
feature like this, and neither could Matthias, obviously!
