Playback on the piano roll

[DanjaHandz]

Heyy, whenever I try to play my music through the piano roll it'll only play if I start at the beginning. Sometime I like to play it in the middle of the track so then I can perfect the beats to the middle of the song. Is there any way I can play the music just from where I want it to begin, instead of having to listen to it the whole way through?
Please help
Thank you
