Thanks Frank,

That did help very much!

I have not used the tutorial so far to build my own sampler. But i  
found some way to figure out how the mentioned loop sampler works.
It does the job very well by now, in some point of view.

When i press a key (maybe "a") it sets the loop in point the actual  
play position and according to that the out point to lets say, 1/16th  
note behind that.
But it takes 1 time until the playhead reaches again the in point  
until the sample really starts looping. Maybe i should start building  
from scratch.

You were a great help! Thansk again
