Question about preset 204

Hello every one

I have question about preset 204
This sound is cool , but I want to hear every single note clearly , but I can't...

When I press the keyboard , I found out some note clear but some note were drop out , it sound like Osc wave shape , and I try everything on the front panel , but nothing change

I noticed someone have the same issue on preset 878 , I've read that , and my sync button is off

Can someone explain this to me?
Sorry for my poor English
