I really want to know how i can make a sound. Im using FL Studio and I hope I can make this sound one time. The sound it is about:

Please search on YouTube:
Mij niet eens gezien | 00:4 01:07 |
Know No Better | 01:05 01:20 |
One Night Stand | 01:13 01:26 |

Its like the sound of a mixed voice, or some type of flute ( I really dont know what is sounds like). So does anybody knot how i can make this sound? It would help me a lot, because it would finish my song.

I hope somebody can help me,

Thank you!
