Wierd Oscillator Problem with Sylenth1

I was looking at a pure saw in Sylenth1 through a spectrum analyzer, and the notes C3 and above have some part of the very high end cut off. Once you press B2 or anything lower you get those high end frequencies back.
I was comparing it to Twin 2, and Twin doesn't seem to do this. |

Is it something really obvious that you can hear? or do you just notice it in the analyser?
If it's the later I wouldn't worry to much about it. It might just be part of the character of the synth. |

| Might be an anti aliasing filter kicking in. Or you could be running into the top end of the sample rate. |

most likely this |

| It's in the 15k-18k range, but I always thought it sounded a bit "dull." |

| its done on purpose to reduce cpu, so those frequencies are taken away |

Ooo, ok. Thx. |

how so ? It would need to filter out those frequencies which would require cpu cycles. Seems the aliasing issue would be more the case ? Again not sure as I don't use it. |

No its not filtering, it it were a filter you would see a falloff, and there is no, the harmonics just stop. So its being band limited, so it has to calculate less harmonics, or its using some other method that I dont know of. But lennard said himself its there to reduce cpu, Im just saying what he says :) |

I remember reading that. btw, if you up the sample rate it doesn't get cut off. So there, problem solved... |
