Still Struggling with Quantizing HALP

This goes into the CV input of Intellijel Quac VCA. You can hear the aliasing best if you use a signal without a lot of high frequency content, like a sinewave bass or sawtooth wave with low pass filter rolling off all the highs. Use headphones.

Aliasing? From an envelope?
How shall that technically happen?

As I previously wrote, the only thing I could imagine is some sort of AM caused by early or late oscillation. I'd need a project file to check on a scope.

Have you tried with a different VCA?

Something to look into.

How could that possibly be aliasing?
Provide a project that shows this behaviour. That's better than this guess work and hearsay.

Kind regards,
You sound like a pretentious know it all. If you don't believe me or you don't have the blip in your envelopes than good for you. Please get out of my post and keep your unhelpful commentary to yourself.... 


Edit: here is thread from muffwiggler where Danjel from intellijel is quoted about aliasing in the 12bit envelopes used in Quadrax and how the solution was a software fix... so it does happen...

"Only a partial quantity of the first batch had 12bit DACs. The rest of the batch had 16bit and the next/subsequent batches will have 16bit as well.

The 12bit DACs actually worked great and you would be hard pressed to hear a difference between the 12bit and 16bit when used as envelopes/LFOs. They are clocked at 48Khz so it is very fast update rate.
The only issue was some aliasing due to quantization error noise that could be faintly heard in the 12bit version. This issue was mitigated with a software update that employed a special form of dithering."
