Re: Undo Problem in Loop IV?

["pboss _" <pattyboss@hotmail.com>]

Mathias,
    Thanks for the response, i'll experiment some more with all of this.   
i 
AM using the unit differently that i was when i had loop-III in it).   
here's some comments from me to kim flint, which includes a question that 
you may have thoughts on:

Kim,
   "...... The most interesting thing, is the fact that, " The Echoplex 
considers it a change to the loop anytime Feedback is less than 100%, so 
it 
saves the altered version of the loop to new memory"  I never knew this 
even 
after combing the manual.   WOW.   big point.
   I think that what has thrown me is that the UNDO button is not 
available 
after doing a multiply of 4 cycles, subsequent to a first-recording of a 
short cycle, in order to get back to the original first short single cycle.
   In other words, even thought the very first cycle SHOULD be in memory 
(without overdubs), along with the 4 cycles of copied / multiplied 
material, 
the UNDO button is only lit during the first cycle and does not give me an 
opportunity to go back to that first single cycle, which for my new 
applications (unlike my uses while i used loop III v.5) is important to be 
able to do.
   If i press UNDO during that first cycle it erases all of the new 
overdub 
except the material added during the first cycle.  After i do a long 
press, 
it is not available again at all, in order to get back to the one, 
original 
single cycle.
  Do you agree that that first cycle should be available (based on memory 
installed, of course) using UNDO, and that it is not available?
  At this point, this is more of an academic question, because i think 
that 
a short use of overdub before attempting any multiplies will work for me i 
hope."   (or i can use your suggestion, Mathias below)

No, its not a bug, but when you use Multiply immediately (without doing 
some 
Overdub or FB reduction) after Record, you get a problem really.

Just imagine how the sound is kept in memory:
You have one cycle recorded and we keep coping that to another cycle, 
ready 
to register eventual changes. As long as you dont do anything more, we 
just 
alternate between those two copies.
Now you do Multiply, which copies one of those cycles (depends on when you 
press Multiply exactly) 4 times with your new overdubs. So you have 5 or 6 
cycles in the memory now.
Now you want undo all overdubs. But we dont have 4 subsequent cycles 
without 
overdubs in the memory!

So the solution is:
Multiply by 1 (press Multiply twice in a row) at the beginning of the 4 
cycles
Then press Undo to get rid of the overdub on that cycle
