Dear all,

I'm trying to change at k-time the starting point of the loop with the flooper2. With the instrument I'm using, the starting point (kloopstart) doesn't move as I would expect. He loops when kloopstart=0 and after that he just continues playing without looping - this means that the kloopend ist not set correctly.

Ok, I had a look at this. I think what happens is this. If loopstart is given a start time 
beyond the current position, the table would be played until that loop position is reached, 
then the loop starts from there. 

I tried for instance using this

 kloopstart randomh 10, 20, 2

and the loop starts at random positions,
but when it’s ahead, the table will be played
until that position is reached.

If you lower the frequency you will be able to check
this out.

kloopstart randomh 10, 20, 0.1
printk2 kloopstart

If the range of random is the whole file, the chances of having to wait until
the loop occurs are bigger.

OK, that's a good explanaition! Thanks for taking a look.
