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:
This is my current conclusion about a work around: (copied from a note to
Kim)
"Yes, it seems to work by turning the feedback knob slightly once during
each repeat of the original single cycle, for one times less than the
intended multiply. Then, doing the 'real' multiply. Lots of work, just
to get back to the original cycle! Oh well, at least in live
performance
cases where i need to build up the layers, then scale it back down to the
fundamental cycle (for working with dancers in this case) i think i can
use
this trick."
Thanks to Mathias and Kim,
Patty
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
