Cherry Audio Forums

Hi,

Just saw this section of the forum for the first time. There was a discussion many months ago over here in another section about the aliasing problem with examples:

viewtopic.php?p=11196#p11196

Wondering if it's an easy bug that can be fixed. Thanks.

Bump. I really wish the aliasing problem on the CP3 would get fixed.

Only in the REV 1 case, with high-pitched oscillator, can aliasing clearly be seen. So there's definitely a case for internal oversampling in the CP3 module when switched to REV 1 mode. Whether x2 oversampling would fix it, or it needs to go higher still, I don't know.

The direct output of the ...

I said I had CP3's ("Rev 1"), not CP3A's ("Rev 2"). I'm aware of the quirks of this discrete transistor module, I also know that it does not behave like this in the analog realm.


This is because you have two high-bandwidth oscillators beating against one another and fed through a distorting ...

OK.

if you don't have the software you can download a free demo version if you don't believe me...lol. This was just one quick obvious example, there are plenty more anyone could come up with.

I have no stake in this and I haven't got the first clue with respect to the issue. Also I am sure that ...

Just to show a simple example of what's happening, here is an audio file and screenshot of a simple patch. Once I start to detune the oscillators in this example, you can REALLY hear the obvious aliasing.


Thanks for creating and uploading the file and screenshot.

I honestly think that you're ...

Would be great to have a huge Moog System 55 vst with 4x oversampling based on the terrific VM 900 collection.

Don,t you agree?


I haven't found VM900 to suffer much from aliasing. Is it a significant problem for you?


It has been a huge issue for me. And once you hear it, you can't ...

The Rackmode FS does not include separate up/down outputs like the VM900 version does, just a mixed output. Which is disappointing, because I the separate outputs panned hard left/right for stereo imaging.
