Re: sample based looping vs. delay looping

["Scott McGregor Moore" <scott@dreamstate.to>]

The "overdub on an empty loop" method
is a good workaround for almost any looper
to avoid loop-point artifacts on droney/floaty material.

I have a Gibson echoplex and I just acquired an electrix repeater.   One 
of my primary goals in looping is to create multitimbral
sustained ambient drones.  the echoplex does this very nicely with no pops 
or other artifacts that occur as you record over the
start point of your loop.   I was hoping to get a more versatile (and 
stereo) version of this same ability in the repeater.
Unfortunately, this was not to be. After some experimentation, I 
discovered that on overdub, as a drone or sustained note was
recorded over the start point, there was a distinct artifact (a popping 
sound sometimes, an amplitude inconsistency others).  I
finally decided that this was because the echoplex is based on a delay 
architecture rather than a sampler/recorder architecture like
the repeater. I think what is happening in the repeater is that on overdub 
the sample is actually mixed and resampled with each pass
rather than the more traditional method of creating an infinite delay loop.
