purpose of "Feedback" (was RE: repeater question)

[PMimlitsch@aol.com]

First: many thanks for the responses/ clarifications regarding 
"Repeater's" 
feedback capabilities.  Although it looks like I'll still need to keep my 
multi looper set up (presently 2 DL4s, RDS8000, Vortex) the "Repeater" 
will 
fit in nicely and provide more options.  Waiting for the day when all this 
stuff can go on a notebook computer....

want to control it? >>

"Feedback" is basically the fade level of previous layers in a digital 
delay/ 
looper.  Control of this level lets you either freeze a loop (100% 
feedback) 
at its present state, let old layers fade as new layers are added (<100% 
feedback), or let the loop on one looper fade as you're adding stuff to a 
second looper.  Runing multi loopers and hop-scotching betwixt and between 
is 
the best way (at least my favorite way) to continually evolve textures/ 
themes etc.  One example that works effectively in a performance situation 
is 
to develope a real "pretty" ambient type texture on one machine, maybe do 
a 
little theme playing/ improv. over top, then start gradually building 
darker, 
more "violent"/ "frenzied", textures on another looper to the point that 
your 
original "mellow" texture (on machine 1) is now obscured.  After building 
things to a musical climax you then set machine 2 to gradually fade out 
and 
slowly, out of the aether, your original mellow loop appears.  Playing 
this 
"tension/release" game is what makes linear music interesting, especially 
in 
extended improvs. - paul
