Noisy in lower frequencies for basic waves

Noisy in lower frequencies for basic waves

I feel like I've heard this noise in other p12 demos on youtube so perhaps others are experiencing it too? Here's a recording of a basic pulse wave with a filter cutoff set to 54 (4 pole).

I hear the noise using sawtooth and even sine waves. Is this normal? Reminds me of the old digital synths - the lower the note, the more noise you'd get.

Here's a patch to demonstrate. I tried calibrating the filters to no avail.

Hi,

Hope this helps,

Thanks Martin - your clip definitely sounds more like it!

FWIW I spoke with DSI support and it looks like my board will need to be replaced/repaired.
