So I read this module has noise issues? Or was that a concrete batch?

I was planning to get one especially because it's stereo but now I'm not so sure.

There's a noise fix on the website:

I am taking commissions for synth builds. UK ONLY for now. DM for details :)

You can find my modular synth album here - enjoy!

No noise issue with mine bought 2 weeks ago. New firmware was flashed before I test it.
First tests

mine still has crazy high frequenzy noise issues :/
any ideas?
