So it’s an Ableton issue? The NC is just a core compliant device and won’t/shouldn’t make your DAW crash. Have you reached out to support@neuraldsp.com?
I guess it’s Ableton + Nano issue. I’ve reached Neural support and I don’t think there’s easy solution.
Anyway for me as a customer it’s disappointment when I have to write to Neural and Ableton support because main functionality of device is not working.
