I agree more even:
As said before, the point where looping really started for me.
The Plex uses a 256 step value and filters it almost evey sample so you can
smothly and quickly change it. I strongly suggest a pedal.
In longer loops you maybe want to grow only a part of it:
For example: Open +Overdub+ and reduce Feedback while opening the volume
pedal so the sound you hear from the Loop will be replaced next time around
by the one you fade in now. Not very difficult to imagine how it will
Then as your note fades, you open Feedback again and have a phase of the
loop as it was before.
+Replace+ is a function we have for this, but is to hard for most
aplications because it chops off/on. With the FB pedal, you do it more
creative and smooth.
Sometimes in long loops (like 25sec) I start increasing the dynamics every
turn around, rather taking back one part and then crescendo in to the full
As it does not make sense to infinitally increase the content of the
memory, we reduce automatically the FB a little while +Overdub+ is on. This
prevents from the worst noises when somebody forgets +Overdub+ on.
When you reduce FeedBack, **reduce loop time, too!**
(Million times executed experience - how it works for me):
Most music (and stories in general) has its static phase (contemplation,
solo) and its dynamic phases (walking, discovering).
Obviously, FB open is for the static and reduced for the dynamic phase.
Since in the static phase you have time, you will multiply and increase
loop time to make the loop more interesting, maybe less obvious.
Then, when you enter a dynamic phase, its a drag, because changes take to
long, or take a too radical reduction of FB which cuts the flow.
So you reduce FB little, but also reduce loop time! If the loop is rather
an educated one with a harmony sequence, built with +Multiply+, you will
aply +Multiply+ by 1 or 2 when the basic harmony comes back. The loop stays
on this base, maybe 4 or 8 times shorter, which gives you the chance to
change it gradually and then build (use +Multiply+ again) a new harmony
If the loop is rather of the anarchistic/ambient kind, you can reduce it
with +Unrounded Multiply+, which is called by the RECORD following the
MULTIPLY key. This way you can cut out any bit, as short as you want, mayb
+Unrounded Multiply+ 2 or 3 times in a row, to really chop up the worm
before the part with the heart grows again with more heads even... urgh,

I did not try this and do not even feel like, right now. Just thinking:
I think you will use this external FB path only every now and then, and
keep the loop going with its internal FB. So once you set up the mixer
conection with the Looper feeding the effect and the effect feeding the
looper, you can use the +Replace+ function to switch to the external FB
With +Overdub+ it will grow, which might be usefull sometimes in such a
To load the loop, you would have to disconect the effect, either with its
+bypass+ function (if it mutes the effect) or by closing the effects
channel or Aux knob.
