Well if the Looperlative doesn't have an Undo then I guess I don't 
want it, so the point's moot.  But plowing on with the geek speak:

With a 24bit/48khz sampling, this gives
- about 932 seconds mono
- or 466 sec stereo
- or 58 sec per stereo track if you use all the 8.

466 seconds is less than 8 minutes, total.  So I guess I don't 
understand where the  "10 minutes per track" came from.  Could 
someone please clarify this for me?

Going back to Undos, per the "Undo" section in the EDP manual, each 
time you do an overdub, the entire loop is copied to a new section of 
memory, if one is available.   That's assuming that there's no memory 
fragmentation which would mean you would have even less memory to work 

Looking at a standard 32-bar AABA song format with two beats to the 
bar and each beat at 80 bpm, one track takes 64 beats/tune divided by 
80 bpm equals 48 seconds.    Let's say "one minute" just to make the 
calculations easier, especially since, as I've said, my loops on 
their own tend to be about 100 seconds long.

It's typical in a live situation for my band to play a song for 10 
minutes. Sometimes we go for 20 minutes.  What I'm using the EDP for 
is to make a duo or a trio sound much bigger than it is.  I assume 
that people like it because we get paid for it.

So if I lay down a riff over two bars, tweak it some and then 
multiply it over the tune that's one minute plus the length of the 
riff including overdubs.  A two-bar riff may be quite complex and 
require 4 or 5 overdubs which takes the equivalent of memory of 
easily half a minute, maybe as much as a minute  The second time 
through I add some structure.  That's three minutes gone.  Now I 
start adding some melodic fragments on the turnaround or chord stabs: 
four minutes.  Now I do a LoopCopy to save this to another loop so I 
can go back to it: five minutes. Now I do a solo overdub: six 
minutes.  Now I double my solo and put down a harmony part: seven 
minutes.  Now I LoopCopy to another loop to save it: eight 
minutes.  If I want to do anything else, I screw up my undo and I 
need the undo in case  the latest bit doesn't work.I still have three 
to thirteen minutes left to go. But I do have two cool LoopCopies I 
can go back to.

"Ah but you didn't use your LoopCopies", you say.  Well, not 
yet.  But I might want to do a breakdown, I might be saving a loop or 
two to guard against mistakes.  I'm a band member, not a soloist, I 
don't have as much freedom to move as a lot of solo loopers.

Now don't get me wrong, I love my EDP.  But the EDP's Undo limitation 
and the lack of Undo in Looperlative are a serious consideration for 
me.  Storage is cheap, give me more storage.
