HD500x Loop Memory Store and Multiple Loops?

[xguerra]

I own a POD HD500x.

 

My questions are:

 

1) How long does it usually store a loop in its memory before it deletes it?

2) Is it possible to start and stop multiple loop routines or individual layers?

 

Thanks!

stores it until you turn it off or engage the tuner.
