not really easy

Hi .
I try to make a sample player which special markers function.
First when i click on play, sample start to play at the begining of it lengh
when it meets the first marker (0), it's doing nothing, when it meet the second (1) it return to the first (0) until i click on a play or continue
button (2 possibilities).
if i play on the next button, it goes directly on the marker one and make a loop between the (1) and (2)
if i click on continue button, it does nothing but when it meet the next marker it doesn't make a loop and go to the following marker.
it works like the old sequencer.
last option that i'd like, choose which marker make a loop.
