Notes are Cutting eachother out

[ELLIOTGRAVES]

I am playing two different patterns at the same time (one in track 2, the other in track 5) using the same piano sample in each pattern.
when I play the song, the overlapped patterns will cut each other out. For example, It will not allow me to play chords because only one note can play at a time. here is a sample. How can I fix it?
