Hi. I've been demoing the SS-11X and I'm encountering an issue with the convolution engines. I'm getting alias-like artifacts that are very obvious in the sound and not filtered by the cabinet rolloff. Please see the video. Unfortunately the sound did not record.
Thanks a lot for your post!
I've passed it on to devs. Here is what they answered (hope it makes sense, I am translating from Russian):
We were not able to reproduce the same high level of artifacts, as in your video.
Please try to eliminate clipping on the Voxengo input, to make sure it does not affect the sound.
At the end of the video we can see that the artifacts increase after using the Voxengo filter, this is definitely not the convolution engine issue.
Artifacts do exist there, yes, but on the level of -90...-95dB in relation to the main signal.
The reason is that it works with a single precision floating point. It allows to lessen the CPU load with long IRs. We decided it's an optimal solution at the moment.
Here are some videos from devs:
